Full textAbstract:
Introduction
Radiologic Technologists exposed to continuous low dose radiation may have an increased risk for spontaneous abortions. Although the federally mandated radiation dose limit to the developing fetus of an occupational worker is 5mSv, well below the documented threshold of 100mSv, some studies have suggested an increased risk for spontaneous abortions in occupationally exposed females. The effects of exposure to low levels of radiation are difficult to discern from the usual occurrence and are limited in the literature because of the large sample size needed to achieve statistical power. This study contains data from 152,439 self-reported pregnancies and possesses the appropriate sample size to assess the risk of spontaneous abortions incident to radiologic technologists who maintain fetal radiation dose levels within federal guidelines.
Methods
This non-experimental retrospective designed study uses data from the United States Radiologic Technologist Study (USRTS). The USRTS began in 1982 as a joint effort between the American Registry of Radiologic Technologists (ARRT),UniversityofMinnesotaand the National Cancer Institute to study the radiation effects from low-dose occupational exposure. This longitudinal study follows more than 90,000 current and former technologists through periodic surveys and contains a sufficient sample size to overcome statistical power concerns.
The provided data included the order and outcome of each self-reported pregnancy as well as the year of each live birth. The data were therefore manipulated to provide a likely gestational interval for both a reported live birth and spontaneous abortion. After calculating the spontaneous abortion rate for the final sample, a binary logistic regression was performed to determine if levels of estimated fetal radiation dose are associated with predicting the odds of a reported spontaneous abortion. A linear regression analysis was then performed to assess the relationship between the calculated odds ratios of a reported spontaneous abortion as a function of estimated fetal radiation dose, specifically to determine the significance of the linear relationship
Results
The overall spontaneous abortion incidence to the cohort reporting at least one live birth or spontaneous abortion was 14.8%, lower than the reported national incidence of 15-20%. Using up to 1mSv as the reference fetal radiation dose category, the odds ratios of a spontaneous abortion for 1-2mSv, 2-3mSv, 3-4mSv and 4-5mSv were calculated as 1.57, 1.82, 2.11 and 2.15 respectively. This increase in odds was linear with estimated fetal radiation dose as demonstrated by the significant regression equation (F=29.93, p = .01) and an R2 of 0.9089.
Conclusions
By demonstrating an increased risk at levels of radiation as low as natural background, and further demonstrating the risk increases linearly with radiation dose, the Linear Non-Threshold Theory appears to be the more likely risk model for predicting spontaneous abortions in lieu of the belief that a 100mSv threshold must first be exceeded for a radiation induced spontaneous abortion to occur. Application of this model demonstrates the risk of a spontaneous abortion is twice as likely in occupational workers whose fetal radiation doses are closer to the maximum allowable limit of 5mSv compared with those who maintain fetal radiation doses below 1mSv.

Haynes, Kelli Welch. "The Importance of Professional Values From Radiologic Technologists' Perspective." Thesis, University of Louisiana at Monroe, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10749823.
Full textAbstract:
Research on professional values in radiologic technologists’ is practically nonexistent. Though learning professional values is important, professional values have not been identified and articulated by the radiologic technology profession. The purpose of this study was to determine radiologic technologists’ perception of professional values and determine if radiologic technologists feel it is important to articulate professional values. No original research study evaluating the perception of professional values of practicing radiologic technologists was identified. The purposeful, convenience sample of 716 American Society of Radiologic Technologists (ASRT) members represented a cross sectional view of radiologic technologists. The Radiologic Technologists’ Perceptions of Professional Values Scale (RTPPVS), adapted from the Professionalism in Physical Therapy Core Values Self-Assessment developed by the American Physical Therapy Association, was used to collect quantitative data regarding the importance of professional values from a radiologic technologists’ perspective. Results indicate that professional values are important to radiologic technologists.
The RTPPVS revealed that radiologic technologists perceive the seven professional values, accountability, altruism, compassion/caring, excellence, integrity, professional duty, social responsibility, as important. Overall, altruism indicators were chosen as the most important professional value and social responsibility was chosen as the least important professional value. A sample of American Society of Radiologic Technologists members perceive it is important for the profession to explicitly articulate professional values.
This research did not demonstrate a statistically significant difference among the demographic characteristics. There were no differences in perceived importance of professional values based on gender, age, state of residency, education level, years of experience, or job title. Implications for practice indicate a need for the profession to adopt and articulate professional values.

Full textAbstract:
Medical radiation is estimated to contribute to over 200,000 deaths annually. Recent increases in the use of radiation-producing medical imaging examinations have led to increasing cumulative radiation dose to the general public. Multiple measures have been taken to address this alarming trend, including physician education, technologist education on dose reduction, and equipment-facilitated dose reduction techniques. Shield use can reduce the primary beam by up to 95%. Medical imaging technologists are the primary individuals responsible for applying shielding during an examination. Currently, literature shows that technologists are not shielding individuals as often as they should.
After pilot testing, medical imaging technologists were recruited via email to participate in a national cross-sectional survey in September 2017. The survey contained items related to technologists’ demographics, shielding behaviors, and attitudes and beliefs measured at four social-ecological levels – intrapersonal, interpersonal, organizational, and community.
The American Registry of Radiologic Technologists (ARRT) provided a list of technologists’ email addresses from their directory. One thousand six-hundred and sixty-one email notifications were sent out in the summer of 2017. Of those, 218 technologists (13%) completed the survey.
Among technologists who considered their primary modality to be computed tomography (CT), organizational level factors were a positive significant predictor of shielding behavior. None of the four levels were significant in predicting shielding behavior among diagnostic radiological technologists (x-ray). Individual factors were significantly correlated to shielding behavior among radiologic technologists in the intrapersonal, organizational, and community levels. Study results indicated that interventions implemented at the organizational level may be most effective in increasing shield use among CT technologists. Additional research is needed to better understand factors affecting shield use among medical imaging technologists.

Full textAbstract:
This research was conducted to obtain information regarding the feasibility of using non-medical personnel to obtain measurements of radiologic total lung capacity (TLC). Operators from each of four groups (general undergraduates, nursing students, medical students, radiologists) differing in the amount of medical training and/or experience reading x-rays, performed each of two tasks. The first task was the measurement of radiologic TLC for a set of twenty x-rays. The second task consisted of tracing the outline of the anatomical structures that must be identified in the execution of the radiologic TLC measurement task. Data from the radiologic TLC measurement task were used to identify possible group differences in the reliability and validity of the measures. The reliability analyses were performed within the framework of Generalizability Theory. While the results are not conclusive, due to small sample sizes, the analyses suggest that group differences in reliability of the measures, if they exist, are small. The concurrent validity of the measures was assessed by obtaining, for each experience level, the correlation between the group mean radiologic TLC for a film set and the TLC for that patient, obtained from a body plethysmograph. Only small differences in the group correlation coefficients were observed. A liberal test of these differences indicated they were not statistically significant. Additionally, two experience level by film sets ANOVAs were performed to determine possible group differences in how well the actual magnitudes of the radiologic TLC measures approximated those obtained with the body plethysmograph. These analyses indicated that the magnitude of the differences between radiologic and plethysmographic TLC measures were smaller for the undergraduates than for the nursing students and radiologists. Lastly, a number of analyses of the anatomical structure tracings were performed. Few interpretable group differences were found.

Full textAbstract:
Radiologic technologists who transition into the role of clinical instructor are usually expert practitioners but may lack knowledge of best practices regarding student instruction and evaluation. The purpose of this phenomenological qualitative study was to investigate how CIs experience the transition from practitioner to educator and what knowledge or education of best practices of instruction and evaluation they bring to the position. This study consisted of interviews with radiography CIs from one associate degree radiography program in the southeastern part of the United States. While some CIs felt prepared to transition into the CI role, none of them had previously had education regarding instruction. They were provided support as they transitioned, but little formal orientation or training. The results of this study should challenge radiography programs to implement or strengthen current orientation programs for new CIs who are critical to student success.

Full textAbstract:
The purpose of this modified replication study is to examine the relationship between the stress levels and the wellness practices of U.S. radiologic technology program directors and to determine if correlations exist between wellness practices and stress levels of the group. Additionally, relaxation activities and the feelings, characteristics, and symptoms associated with stress were considered. The design of the study was ex post facto correlational. The population of the study was U.S. radiologic technology program directors working in JRCERT accredited programs. The electronic instrument was distributed to 635 program directors through e-mail, with 424 (66.7%) usable returns. Significant associations were found between the management of stress and the balance of wellness practices for the RT program directors. It was concluded that while program directors showed significant control in stressful events and issues, continued efforts are needed to promote wellness practices into their busy lives.

Full textAbstract:
Of the many toxic chemicals released into the Hanford vadose zone over the decades of nuclear weapons production, uranium has emerged as a contaminant of significant interest. The ammonia gas injection remediation method has been identified as a promising approach towards mitigating the risks to the ecosystem by limiting the mobility of the radionuclide in the vadose zone. The remediation method was replicated using synthetic porewater solutions with a range of constituent concentrations equal to that of the Hanford 200 Area vadose zone. The uranium-bearing products of the remediation method were characterized using kinetic phosphorescence analysis for aqueous uranium, scanning electron microscopy with energy dispersive spectroscopy and electron microprobe for imaging and elemental analysis, and a sequential extraction procedure modified for the sample precipitates. Evaluation revealed that the resultant uranium-bearing solids likely took the form of uranium-silicates and uranium carbonates, with the latter being precipitated primarily in mid-to-high bicarbonate samples.

Full textAbstract:
The liver is one of the largest organs within the human body and it handles many vital tasks such as nutrient processing, toxin removal, and synthesis of important proteins. The number of people suffering from chronic liver disease is on the rise, likely due to the present ‘western’ lifestyle. As disease develops in the liver there are pathophysiological manifestations within the liver parenchyma that are both common and important to monitor. These manifestations include inflammation, fatty infiltration (steatosis), excessive scar tissue formation (fibrosis and cirrhosis), and iron loading. Importantly, as the disease progresses there is concurrent loss of liver function. Furthermore, postoperative liver function insufficiency is an important concern when planning surgical treatment of the liver, because it is associated with both morbidity and mortality. Liver function can also be hampered due to drug-induced injuries, an important aspect to consider in drug-development. Currently, an invasive liver needle biopsy is required to determine the aetiology and to stage or grade the pathophysiological manifestations. There are important limitations with the biopsy, which include, risk of serious complications, mortality, morbidity, inter- and intra-observer variability, sampling error, and sampling variability. Cleary, it would be beneficial to be able investigate the pathophysiological manifestations accurately, non-invasively, and on regional level. Current available laboratory liver function blood panels are typically insufficient and often only indicate damage at a late stage. Thus, it would be beneficial to have access to biomarkers that are both sensitive and responds to early changes in liver function in both clinical settings and for the pharmaceutical industry and regulatory agencies. The main aim of this thesis was to develop and evaluate methods that can be used for a ‘non-invasive liver biopsy’ using magnetic resonance (MR). We also aimed to develop sensitive methods for measure liver function based on gadoxetate-enhanced MR imaging (MRI). The presented work is primarily based on a prospective study on c. 100 patients suffering from chronic liver disease of varying aetiologies recruited due to elevated liver enzyme levels, without clear signs of decompensated cirrhosis. Our results show that the commonly used liver fat cut-off for diagnosing steatosis should be lowered from 5% to 3% when using MR proton-density fat fraction (PDFF). We also show that MR elastography (MRE) is superior in staging fibrosis. Finally we presented a framework for quantifying liver function based on gadoxetate-enhanced MRI. The method is based on clinical images and a clinical approved contrast agent (gadoxetate). The framework consists of; state-of the-art image reconstruction and correction methods, a mathematical model, and a precise model parametrization method. The model was developed and validated on healthy subjects. Thereafter the model was found applicable on the chronic liver disease cohort as well as validated using gadoxetate levels in biopsy samples and blood samples. The liver function parameters correlated with clinical markers for liver function and liver fibrosis (used as a surrogate marker for liver function). In summary, it should be possible to perform a non-invasive liver biopsy using: MRI-PDFF for liver fat and iron loading, MRE for liver fibrosis and possibly also inflammation, and measure liver function using the presented framework for analysing gadoxetate-enhanced MRI. With the exception of an MREtransducer no additional hardware is required on the MR scanner. The liver function method is likely to be useful both in a clinical setting and in pharmaceutical trials.

This study aims to investigate the risk of Work-Related Musculoskeletal Disorders（WMSDs）among medical radiological technologists in their operations, as well as applying ergonomic intervention strategies to improve their quality of work life. The Nordic Musculoskeletal Questionnaire (NMQ) was be used to obtain the prevalence of musculoskeletal disorders, A total of 20 responses were received,with the response rate of 100%. The results indicated that 85.1% of the sample consciously perceivemusculoskeletal discomfort.The most uncomfortable body parts were the lower back (55.0%), neck (45.0%), shoulder (30.0%), hand and wrist (30.0%). The results of Chi-Square analysis showed that there existed significant correlations between the prevalence of musculoskeletal disorders and the Age, BMI, fregrenly ofstay-up, fregrenly of smoking, experience of wrrent positionand overall work experience. The results of the MSDs checklist analysis revealed that hand and wrist, back and neck werewith higher risk of musculoskeletal disorders.The results of the BRIEF checklist analysis revealed that neck, shoulder, back and elbow were with high risk.OWAS identified 14.8% of operations into AC2 and 7.4% of operations into AC3, which required corrective actions soon or immediately.The results of the QEC checklist analysis revealed that back, neck, shoulder and arm (81.8% for extremely-high or high) required ergonomics intervention to reduce the exposure levels.In terms of consistercy with NMQ, OWAS outperformed MSDs, BRIEF and QEC.In other words, OWAS can be replaced by NMQ, which saves time for the evaluation with other analysis tools. The potential reasons for musculoskeletal discomfort in medical radiological technologists were awkward working posture and repetitive work, including transferringpatients, helping the patient get to the right position, carrying cassettes with one hand, lifting the patient and positioning cassette underneath him or her at the same time, adjusting the X-ray tube and consoleoperation.It is recommended that medical radiologic technologists should have adequate recognition of the risks they are exposing themselves to.In addition, better manpower planning, improvement of standard operation procedures,and redesign of tools and workstations are needed to help reduce musculoskeletal disorders among medical radiologic technologists.

M.Tech. (Radiography)Knowledge and skills are related to time and become obsolete if no effort is made to update them on an ongoing basis. Continuous Professional Development (CPD) is, therefore, the effort of committed professional practitioners to maintain and broaden the knowledge and skills related to their profession, following completion of formal training. The legal obligation of healthcare professional practitioners is to provide a high standard of care and act in the best interest of patients. To achieve this, radiographers must maintain and strive to improve their professional knowledge and competence. The main aim of this study was thus to assess the diagnostic radiographers‟ CPD participation in Kenya. The study was empirical in nature and therefore relied heavily on perceptions, experiences and observations. Mail questionnaires were sent to 250 radiographers working in Kenya during the time of the study. Self- addressed and stamped envelopes accompanied the questionnaires for ease of reply. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 14.0 and the results were presented in frequency and percentage tables. Cross tabulations were employed to demonstrate and test relationships between variables. Results revealed that a large number (69%) of diagnostic radiographers in Kenya are not participating in CPD due to various barriers. The study, therefore, recommended that CPD for radiographers should be declared compulsory and penalties are introduced for non-adherence to CPD requirements. This could encourage radiographers to keep up to date with modern techniques. The SORK should provide a legal framework for CPD and legitimize the organization and implementation of CPD structures...

People in Taiwan are afraid of radiation injury partially due to distorted radiation knowledge and mis-information. Radiological technologists are routinely exposed to radiation in their work. Radiation technologists should be well-educated in radiation safety. The purpose of the research is to understand the radiation safety knowledge of radiological technologists and the factors that influence this information. The results from this study will offer information for administrative authorities and further research. In this study, it was assumed that higher-educated radiological technologists with recent employment would have better radiation safety knowledge. A radiation safety knowledge questionnaire was adopted from the radiological technologist board examinations. This questionnaire contained a basic radiation knowledge profile. The pilot study sampled 30 radiological technologists from two pre-medical centers. The radiological technologists working at the department of diagnostic radiology, radiation oncology and nuclear medicine in four domestic medical centers were collected by random sampling. The relationship between the radiation safety knowledge of radiological technologists and the factors, including gender, education level, working place and career period were analyzed. A total of 144 radiological technologists completed the questionnaire through a one-to-one survey method. The results indicate a significant difference and correlation between radiation safety knowledge, education level and duration of employment. Radiological technologists with a college level education showed better knowledge than those with a junior college level education significantly. The radiation safety knowledge of longer employment was significantly worse. Other variables, such as gender and different department, were not significantly different in radiation safety knowledge. This study indicates that adequate formal education and continual training in radiation safety knowledge is necessary for radiological technologists. On-the-job training is recommended strongly for radiological technologists in order to avoid occupational radiation injury and decrease the potential of injury for patients.

Used as a reference for future continuing education activities, In order to plan a course that will be of interest to all practicing Radiological Technologists and further study in related fields. The purpose of this study is as follows: 1. Understand the content need of the Radiologic Technologists continuing education curriculum. 2. understand the design requirements of continuing education curriculum for Radiologic Technologists. 3. Exploring the differences in the demand for continuing education courses among Radiologic Technologists with different personal background factors. This research method adopts the questionnaire survey method, and the use of the tool is a questionnaire survey conducted by the researcher's self-edited " Radiologic Technologists continuing education curriculum demand questionnaire". The questionnaire was issued in order to use the opportunity of the annual meeting of theRadiologic Technologists associations of the counties and cities. After contacting the local trade unionists, I will go to the scene to issue and collect the questionnaires and entrust a large hospital staff to issue and collect the questionnaires from the hospital. A total of 334 questionnaires were sent out, 301 questionnaires were returned, and 11 invalid questionnaires were deleted. In order to focus on the southern region, 3 questionnaires except Kaohsiung City, Tainan City and Pingtung County were deleted, and 287 valid questionnaires were obtained. The effective questionnaire rate was 85.93%. After the questionnaire was compiled and analyzed, the following conclusions were obtained: 1.For the content requirements section, most Radiological Technologists are in need of continuing education courses, and judge and plan continuing education courses for the needs of the common and professional courses required by Radiological Technologists. 2.In the course planning mode of the course content, radiation protection courses and Computed Tomography courses are acceptable to most people, regardless of the unit type, the initial and advanced courses, and the series of course modes. In the future, relevant courses can be used to plan the course with the above results. 3.In the course design needs survey, the requirements of the current Radiological Technologists for course design, such as the characteristics of the lecturer, the time of the lecture, the place arrangement and the mode of the course, can be used as reference for the relevant courses. 4.According to the investigation of the difference analysis of the needs of continuing education courses with different background factors, we can understand that under different background factors, the needs of Radiological Technologists for the curriculum are different. In the future, relevant courses can be used to plan the course with the above results.To design a continuing education program for Radiological Technologists in a variety of contexts.

Full textAbstract:
Text in EnglishThe contribution of general diagnostic imaging in the diagnosis and clinical management of patients in rural hospitals of South Africa is enormous. To provide high quality diagnostic imaging services for specific contexts requires radiographers who have up-to-date skills and expertise. Thus, rural radiographers require, over and above traditional radiographic expertise, additional competencies which are unique to rural practice. To date, however, little is known about additional core competencies and skills needed by radiographers working in rural areas. Previous studies have focused more attention primarily on other rural health professionals such as doctors and nurses. The aim of this mixed methods study was to investigate and identify additional core competencies required by radiographers working in rural district hospitals of KZN in order to propose a CPD strategy aimed at rural radiographers. An exploratory sequential design was utilised. There were seven participants in the qualitative phase of the study. In the quantitative phase a convenient sample of 109 respondents was surveyed using a structured questionnaire. Three major themes and seven categories emerged from Phase I of the study. These themes and categories were then used to develop a data collection instrument for Phase II of the study. Collectively, the findings of this mixed methods research revealed that there were a number of additional core competencies such as, but not limited to, teamwork, ability to do basic obstetric ultrasound scans, leadership, management, attitude and behaviours, and reporting on plain x-ray films, all of which are required by rural radiographers. Supporting evidence from the study indicated that the majority of these competencies were either partially or not at all covered in the audited curriculum. The study further revealed that the audited curriculum and the scope of radiography in its current form appear to focus attention on minimum competencies that do not promote the expansion and extension of the role of radiographers in rural areas. The study results also revealed a number of challenges faced by rural radiographers.

Objectives: Due to occupational exposure to radiation, the risk of radiation-associated diseases among radiological technologists was concerned. Despite the expertise in radioprotection, radiological technologists are still likely to have long-term exposure of low dose radiation which might cause significant health impact. Cancers are the leading cause of death in Taiwan. The study investigated the incidence risk of cancers among radiological technologists compared to that of the general population and further explored the related factors on the incidence risk of cancers. Method: This was a retrospective cohort study and the data were derived from the National Health Insurance Research Database. The registry for medical personnel was access to identify radiological technologists. Claim data from 1998-2010 were used for subsequent analysis in this study. There were 1,792 individuals registered as a radiological technologist before 2000. To minimize selection bias, the comparison group was selected from general population after 1:10 propensity score matching yielding 17,920 individuals from the general population. We used the Cox proportional hazards model to analyze the incidence risk of cancers among radiological technologists compared to the general population and to identify the related factors. Incidence risk of specific cancers among radiological technologists compared to the general population was also analyzed. Results: In this study, there were 43 radiological technologists with cancer identified (2.40%) compared to 372 cases in the general population (2.08%). Relative risk of cancer among the radiological technologists compared to the general population was 1.24 (95% CI 0.90~1.70). Relative risk of cancer for male compared to female was 0.60 (95% CI 0.29~1.24). Incidence risk of cancers increased with age and peaked in those aged 65 and older in which relative risk was 10.29. Among the comorbidities, those with a history of hepatitis B had a highest risk of cancers. Besides, pulmonary tuberculosis, thyroid diseases, hepatitis C and chronic renal diseases were also identified as risk factors for cancers. The overall incidence of cancers per 100,000 person-year is higher for radiological technologists than the general population. Specifically, radiological technologists had higher incidences per 100,000 person-year of thyroid, liver, breast, colon, gastric, ovarian, lung cancers and non-Hodgkin’s lymphoma. The incidence risk of leukemia of radiological technologists was not significant different comparing to the general population. Conclusion: In this study, we found, although not statistical significant, a relative risk of 1.24 of the overall incidence risk of cancers among radiological technologists compared to the general population. We found radiological technologists had significant higher incidence per 100,000 person-year than that of the general population regarding overall and several specific cancers including thyroid cancer. This study revealed the possibility of increased incidence risk of cancers. Ongoing attention to the integrity and quality of radioprotection is mandatory.

Medical lawsuits always make medical practitioners, including radiological technologists, face expensive compensation and crime liability. After the research review domestic and foreign researches, we find that there has been no discussion about the causes for medical lawsuits against radiological technologists until 2015. On the premise of the situation mentioned above the research crossed the boundaries of two fields in Medical Radiation and Law to discourse this issue. The research analyzed civil and criminal verdicts since January 1, 1996 to April 30, 2015 from the legal database website of Taiwan Judicial Yuan, and expects to learn about the grounds of medical lawsuits against radiological technologists for promoting the positive relation between medical practitioners and patients.

The medical linear accelerator is generally used to treat cancer in the radiation oncology department in the hospitals. The principle of medical linear accelerator is to generate high-energy X-rays by accelerated high-energy electrons striking high-atomic metal targets. And then these high-energy X-rays were used to treat cancer. Besides the Photoelectric effect, Compton Effect and Pair Production interactions, photonuclear reaction also has a certain probability to occur when the high-energy photon interacts with the metal structure in the treatment head of modern medical linear accelerator. In addition to the photon and electron beams, high-energy medical linear accelerator also generates a small amount of neutron radiation; the generated probability increased with the increased of the nominal voltage of the accelerator. These neutrons will cause metal activation in accelerator treatment head and then emitted gamma radiation, in addition to causing extra dose to the patient, it can also cause the medical radiation technologist received radiation dose while he assisting the patient in setting the position. In this study, two high-energy (10 MV) photon beams of medical linear accelerators were used to evaluate the daily treatment of patients. Referring to the daily radiotherapy procedure of the radiological technologist, and actually exposed through a medical linear accelerator. A survey meter (Atomtex AT1121 scintillation detector) was used to detect and record activation of radiation at different locations in different heights. The radiological technologist received activation radiation dose for treated patients had been estimated with two different types of medical linear accelerators, and assessed whether the dose received by the staff exceeds the official annual regulation or not. For radiation protection personnel in the department using the high-energy radiation therapy facilities, radiation doses in the treatment room due to metal activation of the treatment head have been recognized in this study, and also illustrated the caused occupational exposure and effect level to workers. Through the principle of as low as reasonably achievable, it was recommended that the radiological technologists should carefully arrange the daily radiotherapy procedure . After measurement and estimation, the radiation dose received by the radiological technologists for entering the treatment room to assist the patient in setting the position was approximately 0.234 mSv (Varian trilogy) and 0.115 mSv (Elekta precise) per year, which was within the annual dose limit. Results of this study are provided as a reference to the related radiotherapy department using high-energy linear accelerators.

M.Tech. (Radiography)Systematic implementation of a quality control (QC) programme is crucial for any diagnostic radiology department if consistent optimal equipment performance, quality images, accurate diagnosis and quality services at optimum radiation dose and costs are to be assured. This highlighted the necessity for the Tanzania Atomic Energy Commission (TAEC) to establish a training programme to enable radiographers to implement a QC programme and associated QC measures in their departments. Most radiographers have been trained on the QC programme, however, the level of QC implementation by the radiographers is not established. The aim of this study was to investigate the extent to which the QC programme and associated QC measures are being implemented by radiographers in conventional diagnostic radiography units, in Tanzania. A quantitative cross-sectional study design, using a questionnaire, was conducted on a sample of radiographers who have been trained on the QC programme, and who were practicing in hospitals within Tanzania. The study found that implementation of the QC programme and associated QC measures was poor. Most QC measures were not being performed and that only a few tests were being performed but not consistently. Furthermore, there were no records and procedures available for the QC programme. The challenges identified were negligence by the radiographers, lack of standardized test tools, lack of hospital managerial support, lack of enforcement and lack of motivation and coordination. Multifactor interventions by the TAEC, Ministry of Health and Social Welfare, radiographers and the hospital management teams are needed to improve the implementation of the QC programme.

After enforcing the code of Radiological Technologists, the Radiological Technologist’s specialty is authentically affirmed. For those who devote themselves in the health-care-field, besides incessantly ameliorating professional ability, it needs more emphasis and cultivation from health-care field. Because training an expert radiological technologist consumes a good deal of time, it is valuable to probe into which condition causes resignation and inadaptability of technologists. Therefore this research, in personal character, working pressure and organizational commitment three aspects, will demonstrate the influence degree in resignation inclination. And this research will also reveal the relationship between them. I sincerely expect that the conclusion will be a reference in health-care-field for administering and educating radiological technologists. In this research there are total 800 questionnaires: 435 efficacious questionnaires and 365 inefficacious ones. After analyzing we have following conclusion: 1.Personal character has an extremely apparent influence for working pressure, organizational commitment and resignation inclination. Especially neuroticism, the sub-structure of personality, affects working pressure and resignation inclination more intensively; another sub-structure, conscientiousness affects more in organizational commitment. 2.Working pressure has greatly obviously interrelation for resignation inclination. Especially the individual mental and environmental pressures, the sub-structure of working pressure has more obvious influence in resignation inclination. 3.Organizational commitment has extraordinarily distinct correlation for working pressure and resignation inclination. Especially the value commitment, the sub-structure of organizational commitment, influences more in working pressure and resignation inclination. Radiological Technologists’personal character not only causes working pressure, and further results in resignation inclination. Furthermore, the stress of radiological technologists to organizational commitment also has mutuality for partial personal character.

M.Tech. (Radiography)Conventional film and paper based radiology departments have been replaced by information technology at a rapid rate internationally. The leading technology is the Picture Archiving and Communication Systems (PACS) and Radiology Information System (RIS). The necessity to follow global trends has become more apparent in Africa. Simultaneously, Gauteng has now reached a stage where PACS and RIS have been widely implemented. It has been recommended that radiographers must be prepared for the change in expectations and levels of accountability required when PACS and RIS are adopted into the radiology department. The research question that arises is: What are the experiences of radiographers using PACS and RIS in Gauteng, South Africa? The aim and objectives of this explanatory sequential study was to explore and describe the experiences of radiographers using PACS and RIS in Gauteng, South Africa and to develop guidelines to facilitate the job satisfaction of radiographers in a PACS and RIS-driven radiology department. The study employed an explanatory sequential mixed methods design. The explanatory design is a two-phased mixed methods design. The study began with the first, quantitative phase in which the researcher collected data from the six participating diagnostic radiology practices in the form of questionnaires. For the second phase the researcher interviewed information-rich radiographers who participated in the first phase of the data collection in focus groups. The findings, of this study, indicate that the participants in this study experience PACS and RIS in a positive manner, but that strategies could be put into place to further enhance their experience. Guidelines for facilitating job satisfaction of radiographers in a PACS and RIS-driven radiology department are suggested

Full textAbstract:
Inledning: Att utbilda röntgensjuksköterskestudenter att ta bilder med i första hand konventionell röntgen har alltid varit svårt då man har varit hänvisad till fantomer eller rollspel på grund av strålningen. Med utvecklingen av VR uppkommer dock frågan om det kan bidra som komplement till utbildningen. Syfte: Syftet med uppsatsen var att beskriva om VR kan användas i röntgensjuksköterskeutbildningen. Metod: Studien utfördes som en allmän litteraturöversikt där en kvalitativ och nio kvantitativa vetenskapliga artiklar ingick i analysen efter sökningar i 3 databaser. Resultat: Det mesta pekade på att VR kan vara ett bra komplement i röntgensjuksköterskeutbildningen då studenterna uppvisade större säkerhet i positionering och ökat självförtroende vid bildtagning. Dock upplevdes inlärningskurvan av VR som tidskrävande och behov av mer forskning inom området finns. Resultatet visade även att utbildningsanordnaren måste anpassa och utveckla hur de lär ut. Slutsats: Många studenter är efter avslutade studier osäkra på röntgenbildtagning när de kommer till sin första arbetsplats. Kan användandet av VR i röntgensjuksköterskeutbildningen leda till en högre nivå av självsäkerhet och potentiellt ökad kunskap om positionering får det anses vara fördelaktigt.Introduction: Teaching radiography students to be able to take good quality x-ray images has always been a problem since they have been referred to phantoms or roleplay given the radiation. With the development of VR, the question has been raised if that could serve as a complement. Aim: The purpose of this study was to describe if VR could be used during radiography education. Method: The study was conducted as a literature review where one qualitative and nine quantitative scientific articles were analysed after searching 3 databases. Result: Most findings point to that VR might be a good compliment to regular radiography education since the students exhibit improved patient positioning and enhanced self-confidence while taking x-ray images. The learning curve with VR was however deemed as somewhat time consuming and more research seems necessary. The result also shows that the provider of the education must adapt and develop the way they teach. Conclusion: Many students feel insecure about x-ray imaging upon starting at their first place of work. If the use of VR in radiography education might raise the level of self-confidence as well as potentially increase the knowledge of positioning it might be considered beneficial.

Full textAbstract:
Contexte : Les premières implantations PACS (Picture Archiving and Communication System) remontent aux années 80. Le rehaussement récent du PACS au sein d’un centre hospitalier universitaire a permis d’étudier
l’introduction d’innovations dans une technologie mature.
Objectif : Dans un premier temps, effectuer une revue de la littérature sur les études évaluant la perceptions des utilisateurs de l’implantation des PACS. Deuxièmement, évaluer dans une étude de cas si le niveau d’alignement entre les tâches et la technologie prédit l’utilisation et la perception des bénéfices.
Méthodes : Il y a eu une revue systématique de la littérature afin d’identifier les études sur la perception des utilisateurs du PACS. Une adaptation du modèle TTF (Task-Technology-Fit) développé par Goodhue (1995) a servi de base théorique pour l’étude de cas effectuée par questionnaire auto-administré.
Résultats : Les modèles recensés dans la revue systématique sont mieux adaptés à des nouvelles implantions PACS qu’à des systèmes matures en évolution. Il y a une corrélation significative entre le niveau de l’alignement, tel que perçu par les utilisateurs, et la perception des bénéfices nets, ainsi que l’utilisation de la technologie. L’étude a démontré un écart entre la perception des utilisateurs et celle des développeurs interviewés.
Conclusions : Cette étude supporte la validité du concept alignement tâche-technologie dans l’analyse d’un rehaussement PACS. Il est important de maintenir une interaction soutenue entre développeurs et utilisateurs, qui va audelà de la phase initiale de développement.Context: The first PACS deployments date to the early 1980’s. The recent upgrade of PACS in a university teaching hospital has offered the opportunity to study the introduction of innovations in a mature technology. Objective: First, to conduct a literature review of studies evaluating user perceptions following deployment of PACS. Second, to evaluate in a case study if task-technology fit predicts utilisation and perceived benefits. Methods: A systematic review of the literature was conducted to identify studies evaluating user perceptions. An adaptation of the Task-Technology-Fit model developed by Goodhue (1995) served as a theoretical basis for the case study conducted with an auto-administered survey. Results: The models used in the studies identified in the review are more suited for initial deployments of PACS, rather than mature systems in a state of continuous evolution. There is a significant correlation between the level of task-technology fit and the users’ perception of net benefits, as well as use. The study also revealed a divide between the perception of users and that of developers involved in product evolution. Conclusion: The findings validate the use of task-technology fit to study a PACS upgrade. It is important to maintain a continuous interaction between users and developers beyond the early phases of product development.
