Full textBackground: The radiographers’ competences in the field of radiation protection is essential in ensuring a high standard of patient and staff safety. Several studies have examined various aspects effecting the radiographers’ knowledge and need for further training. Aim: The aim of this study was to investigate how radiographers from two hospitals experienced their knowledge of radiation safety, access to protective equipment and the need for further training. Method: The study was conducted as a qualitative semi-structured interview study with ten radiographers participating. The analysis for the study was done in the form of a qualitative content analysis using a deductive form. Results: The study found a difference between the radiographers’ knowledge in radiation safety and how radiation safety routines were performed. Although most initially estimated their knowledge to be good or sufficient, there were some differences, based on which hospital the radiographers’ worked at. When it came to basic safety equipment there where differences noted between the hospitals, both in terms of access and availability. The availability of continued education varied significantly between the two hospitals. Conclusion: The ability of radiographers to work patient-safe, from a radiation protection standpoint, is linked to their knowledge of radiation safety and the workplace's access to radiation protection equipment. The study showed differences between the two radiography departments that were examined. Differences were noted mainly in terms of access to continued radiation safety education, the availability of radiation protection equipment and the use of protective equipment in daily work.

Full textBackground: Research shows that children are more sensitive to ionizing radiation than adults. X-ray imaging may not be performed unnecessarily and its necessity must exceed the risks. It is important to optimize the imaging and as far as possible minimize the radiation dose without affecting the diagnostic performance negatively. Research shows that even low doses of radiation can cause DNA damage and ultimately induce cancer. Objective: The aim of this paper was to describe methods that optimize the x-ray examination and reduce radiation doses to children in conventional radiography. Method: A literature study whose results are based on 14 scientific articles found in the databases PubMed and CINAHL and manual searches. Results: There were several methods that optimize the x-ray examination and reduce the radiation doses to children in conventional radiography. These methods concern approaches in the examination room, parameters, filtering and new technology. Conclusion: Radiographers’ with knowledge of optimization have good opportunities to lower radiation doses in x-ray examinations of children in conventional radiography.

Full textIntroduction: In health care, methods have been developed whereby the medical staff uses ionizing radiation, so-called X-ray technology. This type of ionizing radiation used in various X-ray machines is produced artificially. Cells in the process of dividing and cells that are developing quickly are more sensitive to radiation than fully developed cells. As a developing fetus has more cell division than younger people, adults and elderly, it is more sensitive to ionizing radiation. Examining pregnant women is a greater challenge for radiographers, having to take radiosensitive fetuses into account. A licensed radiology nurse is responsible for safe and secure care. Patient safety is one of the greatest responsibilities of the radiology nurse, striving for the best diagnostic image quality with the lowest possible radiation dose. Purpose: The purpose of this literature review was to compile an overview of which factors affect the radiation dosage transferred to the fetus, which radiation doses the fetus recives and the effects hereof, when using ionizing radiation in a radiology department. Method: The study was performed as a literature review. Eight scientific articles were reviewed, analyzed and the results were presented in categories. Results: Different factors affecting the radiation dose transferred to a fetus were identified. Fetal development stage, the fetal position, the pregnant woman's size and technical settings were the factors that were important to consider because they affect the radiation dose. Conclusion: By having knowledge of the factors affecting the radiation dose impacting the fetus the radiology nurse is able to work with focus on the patients safety and mediate security to the patient.

Full textThis report presents the development of a measurement device for field congruence measurement between light and x-ray field at conventional radiography equipment. The project resulted in a prototype which uses CCD-line sensors to measure light intensity and determine field edges. In a sensor set one sensor is exposed through a hole in the protective casing while the second sensor is incased and covered with a thin screen of fluorescent material. The prototype is a stand-alone, battery powered unit with an interface were a TFT-screen and buttons is used to navigate in menus. The prototype calculate the congruence within <1mm certainty (theoretically lower). All components are mounted in a 3D printed casing. This work has been executed as a project on behalf of the County Council of Värmland, who provided with support and x-ray equipment for test measurements. The project includes PCB-construction, 3D-design in CAD, electronics construction and software development in the programing language C.

Full textPurpose: To compare the patient's total radiation dose and the examination time from the methods conventional radiography and fluoroscopy during the examination congested knees with osteoarthritis issue. Method: Data was collected by handing a dose protocol in which the radiographers in the radiology department were asked to write down the doses of radiation and the examination time. Data was collected over a period of four weeks in a medium-sized hospital in Sweden. The data collection was compared by one-tail test where a Mann-Whitney U-test was performed with a significant level of five percent to see if the null hypothesis (no difference in the radiation dose or time) was obtained. Results: The study's null hypothesis regarding radiation doses was rejected due to that an average of 444.37 mGycm² (fluoroscopy) and 212.24 mGycm² (conventional radiography) was obtained. The study’s null hypothesis regarding the examination times had an average of 5.08 minutes (fluoroscopy) and 8.48 minutes (conventional radiography). As significant levels of both factors was less than 0.001 the alternative hypothesis was retained due to a difference between the modalities. Conclusion: The study results showed that conventional radiography is the most appropriate method to use regarding radiation dose rate while fluoroscopy is best suited in terms of time. Witch method is most appropriate to use as a standard depends on various factors such as radiation dose, examination time, image quality and ergonomics. Therefore further studies is suggested to compile which method is best to use for all these factors.

Full textABSTRACT Key words: pediatric radiography, access to information, radiographer, Convention on the Rights of the Child Background: It is challenging for radiographers to inform pediatric patients based on the guidelines of the Convention on the Rights of the Child (CRC), Swedish law since 2020. Purpose: The purpose was to find out what radiographers from two hospitals considered to be important information and conditions for providing it to pediatric patients undergoing x-ray examinations. The aim was also to investigate whether the radiographers carry knowledge of the CRC and its significance regarding child radiographs as well as to compare the perception of radiographers from hospital A and B on what information is of importance. Method: An empirical quantitative survey study was made.The sample included radiographers experienced in performing x-ray examinations of children. In total 35 surveys were analyzed. Results: Information about general radiation safety and why the patient should keep still was considered most important. The main conditions for providing information were considered to be a prepared lab, prepared parents and paying attention to the child. The majority replied that radiology clinics did not offer a child-friendly environment. The radiographers broadly agree that they are aware of the CRC’s guidelines and that these are of great importance in x-ray examinations. No significant difference was shown between the hospitals. Conclusion: Respondents agreed that informing pediatric patients about radiation safety and the importance of being still is most important. Radiology clinics were not considered to have a well-adapted environment. Radiographers’ knowledge of the CRC needs to be constantly updated.
