Full textAbstract:
Image quality in chest radiography is an important, but complex, subject. The complicated anatomy of the chest, as well as the various ways that chest disease may manifest itself, require careful consideration of radiographic technique. The manner in which human observers deal with the complexity of chest images adds further dimensions to image analysis that are not found in other radiography examinations. This report describes many issues that are related to the quality of chest radiographic images. In so doing, it relies upon the very extensive literature on this topic, a topic that has been one of the most thoroughly studied in all of radiography. Strategies that are generally agreed to improve the quality of chest radiographs are described, as are approaches to the assessment of image quality.

Abstract Digital radiography systems can reduce radiation dose, this capability was harnessed to explore dose and image quality (IQ) optimisation strategies. Entrance surface dose (ESD), effective dose (ED) and organ doses were determined by the indirect method for patients undergoing pelvic anteroposterior X-ray examinations with computed radiography systems. The IQ of patients’ radiographs was assessed in terms of signal-to-noise ratio (SNR). An anthropomorphic phantom was exposed with varying tube potential (kVp), tube current-time product (mAs), and focus-to-detector distance (FDD) to determine phantom-entrance dose for the optimisation studies. SNR of each phantom radiograph was determined. Patients’ mean ESD of 2.38 ± 0.60 mGy, ED of 0.25 ± 0.07 mSv and SNR of 8.5 ± 2.2 were obtained. After optimisation, entrance dose was reduced by 29.2% with 5 cm increment in FDD, and 5 kVp reduction in tube potential. kVp and/or mAs reduction with an increment in FDD reduced entrance dose without adversely compromising radiographic-IQ.

Background: Intraoral radiographs are essential diagnostic tools in dentistry. Ensuring their quality is crucial for accurate diagnosis and treatment planning. This study compared the quality of radiographs produced by undergraduate dental students and qualified dental assistants to identify common errors and assess improvements following feedback and interventions. Methods: This retrospective, observational study compared the quality of digital bitewing and periapical radiographs taken by students and assistants across two audit cycles, with feedback provided between cycles. The radiographs were assessed using a modified quality assessment scale based on the Faculty of General Dental Practice (FGDP, UK) guidelines. Data were collected from the radiology imaging software, and a total of 100 intraoral digital radiographs were analyzed for each group in both cycles. Results: Initially, radiographs from both groups had issues, primarily positioning errors. After providing feedback and additional training, significant improvements were observed from Cycle 1 to Cycle 2. Dental assistants had a higher percentage of acceptable periapical radiographs, while students excelled in bitewing radiographs. Both groups demonstrated marked improvements, reflecting the effectiveness of the interventions. Conclusions: Continuous training, feedback, and quality assurance measures are vital for improving radiograph quality. A multifaceted approach, including updated equipment and adherence to quality control protocols, can significantly enhance patient care. The study highlights the importance of regular calibration and training for dental professionals to maintain high standards in radiographic practices. Further research is recommended to identify additional strategies for improving radiographic quality.

Full textAbstract:
Mastery of interpretation of radiographic images is a contributing factor in correct diagnosis of conditions affecting the dentoalveolar apparatus. It is therefore essential that students’ perfect these skills while studying for their degrees. Once they embark upon their professional careers outside of the university setting, it is expected that the theoretical knowledge and clinical experience accumulated during the course of their studies will have led to improved diagnostic performance. Objective: The objective of this study was to evaluate diagnoses made using intraoral radiographs by undergraduate students at a School of Dentistry in the South of Brazil, before and after their introduction to clinical practice. Materials and methods: Diagnoses made during the second (T0) and fourth (T1) years of the undergraduate course in dentistry using interproximal and periapical radiographs were analyzed. Descriptive statistics were calculated and the McNemar test was used to compare answers at T0 and T1. Results: Fifteen students answered questionnaires at both T0 and T1. The overall percentage of correct answers was 70.5% at T0 and 61.6% at T1, with a significant difference (p = 0.024). Discussion: This study highlights the need for educational strategies that improve diagnostic competence during undergraduate clinical activities, since radiographic examinations are essential in all areas of dentistry. Conclusions: Therefore, it was concluded that the rate of correct diagnosis of dentoalveolar disorders by intraoral radiography decreased significantly after the initial years of clinical training.

Full textAbstract:
IntroductionAll pulmonary tuberculosis (PTB) cases are presumed to be infectious to some degree. This spectrum of infectiousness is independently described by both the acid-fast bacilli smear and radiographic findings. Smear-positive patients with chest radiographic findings that are typical for adult-type PTB are believed to be most infectious.HypothesisCharacterisation of the presumed most infectious PTB case is possible by reference to readily available clinical features and laboratory results.MethodsRetrospective cohort study of adult, culture-positive PTB cases (151 smear-positive; 162 smear-negative) diagnosed between 1 January 2013 and 30 April 2017 in Canada. We describe cases according to demographic, clinical and laboratory features. We use multivariable multinomial logistic regression to estimate the relative risk ratio (RRR) with 95% CI of features associated with an outcome of smear-positive PTB, characterised by ‘typical’ chest radiograph findings.ResultsBeing Canadian-born, symptomatic, having a subacute duration of symptoms and broad-spectrum antibiotic prescriptions were all more commonly associated with smear-positive than smear-negative disease (36% vs 20%; 95% vs 63%; 88% vs 54%; and 59% vs 28%, respectively). After combining smear status and radiographic features, we show that smear-positive patients with typical chest radiographs were younger, had a longer duration of symptoms (RRR 2.41; 95% CI 1.01 to 5.74 and 2.93; 95% CI 1.20 to 7.11, respectively) and were less likely to be foreign-born, or have a moderate to high-risk factor for reactivation (RRR 0.40; 95% CI 0.17 to 0.92 and 0.18; 95% CI 0.04 to 0.71, respectively) compared with smear-negative patients with atypical chest radiograph findings.ConclusionA clear picture of the presumed most infectious PTB case emerges from available historical and laboratory information; vigilance for this presentation by front-line providers will support elimination strategies aimed at reducing transmission.

The aim of this study is twofold. First, to assess the level of agreement between radiographic damage and functional disability in older people with osteoarthritis. And second, to assess the role of coping skills and sensory pain parameters as sources of disagreement between these variables. To achieve this objective we assess, in a sample of 104 older people with osteoarthritis, the following variables: functional capacity, radiographic damage, pain coping strategies, pain intensity, pain frequency and pain duration. The results show a non-linear relationship between radiographic damage and functional disability, modified by the levels of the two variables. There was maximum agreement between low levels of radiographic damage and of functional impairment, whilst agreement decreased for moderate and high levels of radiographic damage. Certain coping strategies may help to explain this disparity.

Full textAbstract:
Feline hypertrophic cardiomyopathy (HCM) is a common heart disease affecting 10–15% of all cats. Cats with HCM exhibit breathing difficulties, lethargy, and heart murmur; furthermore, feline HCM can also result in sudden death. Among various methods and indices, radiography and ultrasound are the gold standards in the diagnosis of feline HCM. However, only 75% accuracy has been achieved using radiography alone. Therefore, we trained five residual architectures (ResNet50V2, ResNet152, InceptionResNetV2, MobileNetV2, and Xception) using 231 ventrodorsal radiographic images of cats (143 HCM and 88 normal) and investigated the optimal architecture for diagnosing feline HCM through radiography. To ensure the generalizability of the data, the x-ray images were obtained from 5 independent institutions. In addition, 42 images were used in the test. The test data were divided into two; 22 radiographic images were used in prediction analysis and 20 radiographic images of cats were used in the evaluation of the peeking phenomenon and the voting strategy. As a result, all models showed > 90% accuracy; Resnet50V2: 95.45%; Resnet152: 95.45; InceptionResNetV2: 95.45%; MobileNetV2: 95.45% and Xception: 95.45. In addition, two voting strategies were applied to the five CNN models; softmax and majority voting. As a result, the softmax voting strategy achieved 95% accuracy in combined test data. Our findings demonstrate that an automated deep-learning system using a residual architecture can assist veterinary radiologists in screening HCM.

ObjectiveOccupations involving greater physical activity may increase risk for knee osteoarthritis (OA). Existing studies have not evaluated work-related physical activity before OA onset. Hence, we aimed to evaluate the association between work-related physical activity and knee OA incidence.MethodsWe performed a person-based longitudinal study using Osteoarthritis Initiative (OAI) data among people who volunteered or worked for pay without baseline radiographic knee OA or knee pain. Bilateral knee radiographs were obtained at baseline and annual follow-ups. We defined radiographic OA as Kellgren-Lawrence grade ≥2. Questions from the Physical Activity Scale for the Elderly at baseline and annual OAI visits provided information about work-related physical activity level and hours. We performed logistic regression with work-related physical activity level (mainly sitting, standing and some walking, walking while handling some materials) and hours as predictors. The outcome was incident person-based radiographic OA within the ensuing 12 months, over 48 months.ResultsAmong 951 participants (2819 observations), higher work-related physical activity levels had greater adjusted ORs for incident radiographic OA (people with jobs with standing and some walking: 1.11 (0.60–2.08), and walking while handling some materials: 1.90 (1.03–3.52), when compared with those with mainly sitting work-related activity). There was no association between number of hours worked and incident radiographic OA.ConclusionsPeople performing work that require walking while handling some materials have greater odds of incident knee OA than those with jobs mostly involving sitting. Strategies are needed to mitigate risk factors predisposing them to radiographic OA.

Radiography of pregnant patients poses significant challenges to radiographers due to the need to balance diagnostic requirements with the safety of the developing foetus. This article explores the challenges faced by radiographers when conducting radiographic procedures on pregnant women and their foetus and discusses strategies employed to minimize radiation exposure. Key challenges include the risk of foetal radiation exposure, timing of examination, proper positioning of the patient and patient anxiety. Strategies such as radiation shielding, collimation, low-dose techniques and alternative imaging modalities are crucial for minimizing radiation exposure while obtaining diagnostic information. Clear communication between radiographers and patient is essential to ensure the safety and well-being of both the mother and the foetus during radiographic procedure. Radiographers knows the dangers of radiation exposure to fetal health. Now days, diagnostic imaging of pregnant women is increasing. X-ray risks depending on the gestational age of the pregnancy, and other potential health effects. In addition, ethical issues have been considered by improving overall communication to minimize unnecessary radiation exposure to pregnant women and fetuses.

College students experience high levels of stress, especially those in health care programs. The purpose of this study was to determine what factors contribute to Tennessee radiography student stress levels and the methods by which they cope with stress. Additionally, do demographic factors affect radiography student stress levels? The research was conducted February 4 to March 30, 2016. A survey was distributed to students in a radiography program at two and four year colleges in Tennessee. Participants were asked questions on factors that influence their stress levels, coping strategies, and health issues experienced in the past year. Descriptive statistics, independent samples t-test, and Pearson correlations were used to determine what factors influenced student stress levels, the most effective coping strategies, and if demographics affected student stress levels. This analysis revealed that school causes students the most stress, while taking a break was the most used stress coping strategy.

Present and future demonstrator designs were used to demonstrate the quality assurance of welds. The NDT methods tested on prototype demonstrator parts are: visual inspection, radius gauges, throat size gauge, liquid-penetrant testing, magnetic particle testing and ultrasonics with pulse echo and phased array. The other methods like eddy current, time of flight diffraction, radiography, impression test, macro test and infrared thermographs are currently being analyzed along with their inspection costs. The control plans for present and future designs with corresponding present and future NDT methods are suggested to minimize a shift in process. Magnetic particle testing revealed a lack of fusion and cracks for fillet welds, whereas ultrasonic pulse echo and phased array identified an internal lack of fusion, inner pores/slag inclusions on butt welds. Ultrasonic PAUT & TOFD could be used for accurate defect identification and thermography for online identification of lack of penetration, depth of penetration and weld parameters.<br>Weight reduction by improved weld quality (WIQ)

Full textAbstract:
The purpose of this study was primarily to explore the conceptualization of critical thinking development in radiologic science students by radiography program directors. Seven research questions framed three overriding themes including 1) perceived definition of and skills associated with critical thinking; 2) effectiveness and utilization of teaching strategies for the development of critical thinking; and 3) appropriateness and utilization of specific assessment measures for documenting critical thinking development. The population for this study included program directors for all JRCERT accredited radiography programs in the United States. Questionnaires were distributed via Survey Monkey©, a commercial on-line survey tool to 620 programs. A forty-seven percent (n = 295) response rate was achieved and included good representation from each of the three recognized program levels (AS, BS and certificate). Statistical analyses performed on the collected data included descriptive analyses (median, mean and standard deviation) to ascertain overall perceptions of the definition of critical thinking; levels of agreement regarding the effectiveness of listed teaching strategies and assessment measures; and the degree of utilization of the same teaching strategies and assessment measures. Chi squared analyses were conducted to identify differences within each of these themes between various program levels and/or between program directors with various levels of educational preparation as defined by the highest degree earned. Results showed that program directors had a broad and somewhat ambiguous perception of the definition of critical thinking, which included many related cognitive processes that were not always classified as attributes of critical thinking according to the literature, but were consistent with definitions and attributes identified as critical thinking by other allied health professions. These common attributes included creative thinking, decision making, problem solving and clinical reasoning as well as other high-order thinking activities such as reflection, judging and reasoning deductively and inductively. Statistically significant differences were identified for some items based on program level and for one item based on program director highest degree. There was general agreement regarding the appropriateness of specific teaching strategies also supported by the literature with the exception of on-line discussions and portfolios. The most highly used teaching strategies reported were not completely congruent with the literature and included traditional lectures with in-class discussions and high-order multiple choice test items. Significant differences between program levels were identified for only two items. The most highly used assessment measures included clinical competency results, employer surveys, image critique performance, specific course assignments, student surveys and ARRT exam results. Only one variable showed significant differences between programs at various academic levels.<br>Ed.D.<br>Department of Educational and Human Sciences<br>Education<br>Education EdD

No<br>Errors in the interpretation of diagnostic images in the emergency department are a persistent problem internationally. To address this issue, a number of risk reduction strategies have been suggested but only radiographer abnormality detection schemes (RADS) have been widely implemented in the UK. This study considers the variation in RADS operation and communication in light of technological advances and changes in service operation.
A postal survey of all NHS hospitals operating either an Emergency Department or Minor Injury Unit and a diagnostic imaging (radiology) department (n = 510) was undertaken between July and August 2011. The questionnaire was designed to elicit information on emergency service provision and details of RADS.
325 questionnaires were returned (n = 325/510; 63.7%). The majority of sites (n = 288/325; 88.6%) operated a RADS with the majority (n = 227/288; 78.8%) employing a visual ‘flagging’ system as the only method of communication although symbols used were inconsistent and contradictory across sites. 61 sites communicated radiographer findings through a written proforma (paper or electronic) but this was run in conjunction with a flagging system at 50 sites. The majority of sites did not have guidance on the scope or operation of the ‘flagging’ or written communication system in use.
RADS is an established clinical intervention to reduce errors in diagnostic image interpretation within the emergency setting. The lack of standardisation in communication processes and practices alongside the rapid adoption of technology has increased the potential for error and miscommunication.

M.Tech. (Diagnostic Radiography)<br>Radiology is a profession in crisis and worldwide statistics support this statement. By addressing the shortage of radiologists, this crisis could be alleviated. One possible solution is to train qualified radiographers in South Africa (SA) to adequately apply pattern recognition (PR) criteria to the appendicular skeletal system, a gap already identified by Williams, (2006, 2009). This training gap has been investigated on postgraduate level by means of two studies performed by Williams (2006:14) and Williams (2009:15). However, no studies could be found indicating that the gap in training has been investigated and addressed at undergraduate level. The aim of this study is therefore to compare the PR skills among 3rd year radiography students at UJ and CUT on plain radiographs of the skeletal system. Competency will be indicated by test results of 70% and above. The study will take the form of a sequential design within a mixed method approach. Since the researcher aims to utilize a combination of quantitative and qualitative data collection methods and aspires to elaborate on initial findings, this approach is deemed appropriate Results of this study were adequately supported by statistical analysis to conclude that the participants representing the two Universities were statistically similar allowing generalization of results to the population of undergraduate 3rd year radiography students in South Africa. The majority of participants (91.2%) have access to pathology radiographs compared to 72.1% with access to relevant textbooks with most participants utilizing available resources for study purposes. All lecturers are approachable by the participants and all identified PR teaching strategies are effective to a selected degree; Research revealed that South African undergraduate diagnostic radiography students are not able to accurately apply PR criteria at the end of their third year. There is therefore a need for more in-depth PR training in the South African undergraduate diagnostic radiography curriculum.

Full textAbstract:
Invasive fungal infections on haemato-oncology wards present a major challenge. Patients at risk for invasive fungal infection usually have a compromised immune system due to bone marrow failure caused by underlying disease, prolonged neutropenia after intensive chemotherapy, or immunosuppression after haematopoietic stem cell transplantation to avoid graft-versus-host disease. Three major entities—invasive candidiasis, invasive aspergillosis, and mucormycosis—account for the majority of fungal infections. Here, we describe specific host and therapeutic factors predisposing to invasive fungal infection in the haemato-oncology setting. Clinical presentation is highly variable and dependent on the underlying pathogen, organ involvement, and site of infection. Diagnosis is mainly based on radiographic imaging combined with microbiological and histopathological work-up. Various prophylaxis and treatment strategies have been developed, and the evidence for these is discussed.

AbstractThe treatment of locoregionally advanced squamous cell carcinoma of the head and neck (LA-HNSCC) is reviewed, highlighting the milestones in systemic therapy in that setting, with focus on the role of induction chemotherapy (ICT). The road to what is now considered the standard ICT regimen, i.e. the TPF (docetaxel/cisplatin/5-FU) regimen is described, and the differences between the European and the American TPF are discussed. The article describes the respective roles of ICT for larynx preservation, for treatment intensification, its role in patients with borderline resectable or unresectable oral cavity cancer, its role as a selection tool for radiotherapy dose de-escalation in patients with oropharyngeal squamous cell cancer (OPSCC) and its potential future role in strategies aiming at synchronous oligometastatic disease.ICT has an established role for organ preservation in advanced laryngeal and hypopharyngeal cancer and the TPF regimen has been validated in that setting. This approach is presently being compared in a randomized controlled trial to concurrent chemoradiotherapy (CCRT), which in many parts of the world is considered the standard organ preservation procedure. There remains uncertainty about the benefit of the sequential approach of ICT followed by CCRT, despite the fact that ICT significantly reduces the occurrence of distant metastases. It is advised that future studies should include patients who have the highest risk to develop distant metastases, in particular patients with low neck nodes and matted nodes. Moreover, further studies in patients with HPV-associated OPSCC at risk for distant failure (T4 or N3 disease) should be considered for that also. These approaches still need to be confirmed in adequately sized randomized controlled trials. Outside clinical trials, the utility of ICT is restricted to uniquely pragmatic clinical scenarios, such as unavoidable delay in radiation or in the situation that RT is not tolerated or feasible. This can happen when there is severe pain from advanced disease or there is impending airway compromise or neurologic dysfunction that necessitates rapid initiation of treatment. In all those circumstances whether within the context of trials or outside trials, it is imperative that the present backbone of ICT, the TPF regimen, is being administered by experienced oncologists, familiar with the necessary protocols and supportive care requirements to ensure patient safety and maximize adherence throughout the treatment.Future areas of research are the role of ICT in strategies whereby ICT is combined with upfront metastases-directed treatments and the usefulness of targeted agents or immune checkpoint inhibitors in the induction setting. Studies in that direction have already started. Finally, the application of radiographic, proteomic and genomic biomarkers will get attention to further define prognostic groups and guide treatment selection with greater precision.

AbstractImportance: Wrong-level spine surgery (WLSS), a medical error in which a surgeon operates at an unintended vertebral level, is considered a “never event.” However, it continues to be a problem in spine surgery today despite the implementation of preventive measures such as the Universal Protocol. The consequences of this event are severe for both the afflicted patient and the treating physician and may result not only in physical harm but also in costly medicolegal proceedings.Observations: While WLSS incidence varies with the patient population and practice setting, large studies generally report rates below 1%. Given the ubiquity of spine surgery, this remains a concerning number. Risk factors for WLSS can be categorized into three domains: patient factors, imaging issues, and technical issues. Awareness of risk factors allows surgeons to plan for difficulties in level localization. Many techniques for preventing WLSS have been developed, including invasive preoperative marking strategies. Intraoperative radiography or fluoroscopy is necessary but not sufficient for WLSS prevention, in that many errors occur after imaging. The evidence for prevention methods remains of low quality, necessitating future prospective comparison studies.Conclusions and relevance: Consensus has been reached in professional societies: All spine surgeons should implement WLSS prevention protocols. We assess the reported techniques for safer surgery and emphasize one crucial time-out element: the time-out for level localization (TOLL). Addressing WLSS as a problem specific to spine surgery, we show that by using specially tailored prevention strategies, such measures will allow WLSS to become a true never event.

Full textAbstract:
The diagnosis of vertical root fractures (VRFs) is a challenge for dental surgeons because of the similarity of clinical signs with other pathologies. It involves both clinical and radiological examination. Common signs of VRFs are deep localized periodontal pocket, gingival swelling, tenderness to percussion, and radiographic bone loss. The fracture line would be difficult to identify, so an analysis of clinical and radiological data would be required. The use of conservative approaches to avoid tooth extraction is cited in the literature. However, extraction is often unavoidable. The early diagnosis is important because it may avoid unnecessary treatment and excessive bone loss. The aim of this work is to provide more knowledge about the signs and symptoms of vertical root fractures with illustrations by clinical cases.

Breast pain, also known as mastalgia, is one of the most common clinical issues women bring to the surgical outpatient department. The epidemiological, pathological, and radiological aspects are used to obtain a complete view of mastalgia. Most patients expressed concern about cancer rather than debilitating pain that would interfere with their everyday activities. The therapy of patients with mastalgia requires high-quality radiographic and pathology services. Reassurance and appropriate medical and surgical treatment for the source of breast pain can help to reduce morbidity and improve the disease's outcome. In this chapter, the investigation of several current therapies and yoga therapy are discussed for cyclical mastalgia (CM). The research also looked into the impact of current therapies on psychological outcomes. The results indicated that the biochemical clinical trial is effective with side effects, and the primrose oil and seed treatment is ineffective. To handle mastalgia sufferers, integrated yoga therapy provides a high-quality trial.

Full textAbstract:
Abstract There is a complex network of ~800 miles (1280 km) of above ground pipelines in one of the largest oil fields on the North Slope of Alaska. This infrastructure has been in operation for nearly three decades, transporting crude oil, water and gas. The vast majority of the piping network is insulated with polyurethane foam over bare steel, and is therefore susceptible to corrosion under insulation (CUI). The sheer magnitude of the number of locations susceptible to CUI poses integrity management challenges that call for a better understanding of damage onset and progression rates as well as underlying causes. Radiographic testing, visual inspection, and refurbishment data were analyzed for ~73 miles (117 km) of pipelines where complete external corrosion inspection histories were available. The analysis showed that the accumulated damage distribution over time could be fit to Weibull curves, which appear to correlate with the total number of CUI repairs and refurbishments that need to be done each year. The Weibull curves generated were employed to predict the number of CUI susceptible locations that would need repair or refurbishment each year for all 800 miles of pipelines in the field. The model can be further used as input to risk assessments to support maintenance strategies, and as background rationale for budgeting and manpower optimization for inspection, repair and refurbishment activities.

An OLF document was compiled during 1990’s and the visual inspection part of the document was used in the ISO 14692, part 4 [12] with requirements and defect criteria. Additional parts on ultrasonic and radiographic examination have been included in the Norwegian standard Norsok M-622 [1]. However, we would like to publish the full version of this document and make it available in the public domain. Some of the methods described is well developed, while others still would require research efforts to make the techniques practical useful. For practical use, the visual examination with failure description, acceptance criteria and corrective actions are most developed. Further, radiography has been useful in several projects in assessing the quality of adhesive joints. The ultrasonic testing is expected to become better to use as the equipments and methods are developing. Every reasonable effort has been made to ensure that this publication is based on the author’s best knowledge.

Full textAbstract:
In orthopedics research, assessment of fracture healing progress is vital for evaluating treatment strategies and drug effects. Currently, biomechanical testing represents the ‘gold standard’ for determining the extent of healing, with the parameters of stiffness and strength most often reported. Unfortunately, such testing requires destructive examination of samples, which allows healing to be checked at only one time-point per animal. Thus, evaluation of healing requires large sample sizes to achieve statistical power. In contrast, longitudinal studies of individual animals allows for self-comparison, which is more reliable, and can be used to evaluate bone healing as time elapses. Recently, longitudinal radiographic assessment of bone healing in rats, using parameters such the level of bone mineralization, morphological changes, and distribution of the mineralized bone, has been reported. However, the ability to quantify the biomechanical properties of healing bones based on longitudinal radiographic images provides an tremendous opportunity to increase the value of such studies.

Abstract For a safe, reliable and efficient operation of facilities, knowledge and information of the condition and integrity of the assets are essential. Therefore, assets must be inspected on a regular base, preferably with non-destructive methods. Many of such methods are known in the industry (e.g. radiographic, magnetic, ultrasonic testing etc.), however their application is often restricted and the resulting data from the inspection is not adequate and/or sufficient for the asset integrity management. Due to advances in ultrasonic hardware and sensor technology, a novel approach for non-destructive testing based on ultrasonic imaging, IWEX, has been introduced. With this approach, an ultrasonic ‘fingerprint’ called a Full Matrix Capture (FMC) data set, can be measured. With the FMC data set representative 2D and 3D images from the interior of metal components (e.g. welds) can be re-constructed. For the inspection of such components, real time scans can be made in order to reveal possible flaws. The IWEX technology has already successfully been applied for the inspection of girth welds in newly constructed pipelines ([1], [2]). Furthermore, the method has recently been recognized by international codes and standards (ISO [3], ASME [4]), which opens the door for both new construction and in-service inspection applications in industrial facilities. In this paper, we will present the principles of ultrasonic imaging with the IWEX method. An example will be presented of an actual use case, concerning the inspection of welds in stainless steel pipes in an industrial facility. The welds contained cracks which were in some cases detectable with radiography, but height sizing was not possible. With the IWEX method, the cracks could reliably be detected, and it was possible to determine the crack heights. The height sizing accuracy was confirmed with known artificial targets in a representative reference block. Based on the accurate sizing results, it was possible to perform a fitness for service analysis which allowed a safe continuation of production in the facility. The use case of the IWEX method illustrates how this new technology facilitates improved maintenance strategies for the industry by enabling the possibility to obtain sufficient and accurate information during inspection. As a next steppingstone the 2D and 3D images can be stored digitally such that they can be used to monitor and predict the condition of the asset over time using novel analyses concepts such as pattern recognition by neural networks.

Full textAbstract:
The ability to detect a normal from aberrant bone healing cascade during the acute fracture fixation period (1–3 weeks post trauma) is critically important to insure a favorable clinical outcome for many complex fracture cases. Radiographic evaluations do not have the inherent fidelity to make qualitative predictions during the acute healing phase. Early detection of an atypical healing profile would allow for revision strategies to be employed without the need for expensive and undesirable follow-up surgeries. In an effort to address the critical need to diagnose the course of bone fracture healing in the vitally important early healing phase, our research group has developed a radio frequency (RF) strain sensor that takes advantages of the recent advances in meta-materials and micro-electo-mechanical systems (MEMS) technology. Our MEMS sensor is biocompatible (bioMEMS), inductively powered and monitors the surface strains on implanted hardware [1, 2]. Another novel feature of this new sensor is that it does not require an internal-external physical connection to sense and transmit in vivo biological data. The essence of the sensor’s design is that straining the integrated RF bioMEMS circuit results in a shift in its resonant frequency (ResF). Through telemetric detection of this ResF shift, it is possible to longitudinally monitor the temporal changes in hardware strain. It is well understood that that as proper fracture healing progresses (i.e. increasingly stable tissue(s) stabilizing the fracture sight) that the load/strain born by orthopaedic implant diminishes. Therefore, telemetric measurements of our bioMEMS system (i.e. hardware load/strain) provide direct insight into the degree of fracture stabilization and healing.

Abstract The COVID-19 pandemic has profoundly disrupted educational systems globally, compelling rapid adaptation to maintain continuous learning. Radiography education, heavily reliant on practical training and clinical experience, faced unique challenges during this period. This paper aims to analyze the impact of the pandemic on radiography education, focusing on major changes, challenges, and innovations introduced. The objective is to examine how digital technologies like online learning platforms, virtual reality (VR), augmented reality (AR), and gamification have been utilized to address these challenges. A narrative literature review was conducted using articles from PubMed and Google Scholar, with keywords related to radiography education and COVID-19. Results indicate that while online learning and digital tools provided essential continuity, they also introduced challenges such as digital divide, screen fatigue, and reduced student engagement. Innovative teaching methods like flipped classrooms and screencast feedback have demonstrated potential in improving learning outcomes. The study highlights the necessity for ongoing professional development for educators and suggests adopting a hybrid learning model as a future direction. This review underscores the resilience and adaptability of radiography education during the pandemic and proposes strategies to enhance educational quality in a post-pandemic era. Key words: COVID-19, education, radiography.
