“…This leads us to question whether student radiographers (and perhaps qualified staff) are wholly examining all dependent features on a digital system. There has been acknowledgement that radiographers may be striving for aesthetically pleasing images in digital radiography, 27 thus with little attention to the EI value, this strengthens previous assertions that aesthetics of discerning image quality remains superior over optimal exposure delivery. If transferable in other contexts it raises an important issue for clinical and academic practitioners whereby alternate pedagogical and andragogical tools and assessments may be needed in order to ensure that students appreciate and reflect on the EI in clinical situations.…”

“…This is a reminder that diagnostic radiography remains both an art and science, where subjectivity is central to the practice development of student radiographers. 27 Students aim to 'do well' and keep doses 'as low as reasonably achievable', yet they identify and witness complacencies when supervised. This may be important to understand further as it would seem that the development of 'bad habits' amongst clinical supervisors may creep into everyday practices.…”

Investigating perceptions of ‘dose creep’ amongst student radiographers: A grounded theory study

Introduction:The dose creep phenomenon is now a widely recognized concept in diagnostic radiography in light of recent technological advancements transnationally. However, this still remains underexplored amongst radiography students preparing to enter the radiography profession. In response, this study explores the perceptions of dose creep amongst undergraduate student radiographers. Methods: The methodological approach utilized in this research study was grounded theory. The qualitative approach aimed to uncover findings from a higher education institution in Australia. Six students were recruited and took part in semi-structured interviews. This enabled the exploration of previously uncovered data, leading to the construction of original theory within the clinical and academic environment. The data analysis employed was constant comparative analysis (CCA). Results: A number of insights emerged from the qualitative data set. For instance, the radiography students understanding of the term 'dose creep' and decision making leading to dose creep in the clinical environment is captured. This is further supported with assessment of image evaluation determining appropriate exposure factor selection and future impact upon graduation as diagnostic radiographers. The findings identify some important learning needs and actions for both clinical and academic settings which may help foster good use of X-ray exposures. Conclusion:This paper concludes by affirming some challenges surrounding optimal exposure selection and the known phenomenon, dose creep. Further, this study identifies the importance of learning and teaching in the clinical environment whereby learned behaviour leads to suboptimum practices. Implications for practice: This study advances the existing evidence base by providing a unique lens into the knowledge and understanding of dose creep amongst radiography students in both academic and clinical contexts. It is anticipated this paper will help practitioners and educators better understand potential instances of dose creep within the clinical environment.

“…An observational study from the United Kingdom found that radiographers collimated/cropped images at the post-processing stage with collimation/cropping ranging from 1 cm to 5 cm. 39 Increasing the irradiated area outside the area of interest contributes to radiation dose and impedes image quality. 40 A contrast in responses from a participant's "yes" P6 to radiation protection practices being evident to an upset and emotional participant's story elucidates the spectrum of radiation protection practices in South Africa: "So you see, I have seen something just here that really upset me actually ….…”

Introduction: Radiation protection is multifarious, and consequently, a radiographers' application of radiation protection is multifaceted. Studies have shown varying radiation protection practices among radiographers. The first quantitative phase of this explanatory, sequential mixed-method study used the theory of planned behaviour to explore South African radiographers' radiation protection behaviour. Overall, South African radiographers' attitudes to radiation protection, subjective norm, perceived behavioural control, and radiation protection intention was high. This second phase of the study aimed to explore the reasons for South African radiographers' radiation protection practices. Methods: This study used an exploratory and descriptive qualitative approach. Data was collected through 13 in-depth semi-structured telephone interviews. Thematic analysis was used in order to uncover original phenomena. Data saturation was achieved and the study adhered to trustworthiness and ethical measures. Results: Thematic analysis identified two themes. The participants had the appropriate radiation protection knowledge, but radiation protection compliance remained a personal choice. Impediments such as feeling rushed during imaging of trauma and challenging patients, patients knowledge of radiation protection, resources, imaging referrals, inadequate training when transitioning from analogue to digital radiography and managerial support contributed to radiation protection compliance. Strategies such as further education, research and a change in mindset were suggested to further foster radiation protection compliance. Conclusion: Even though participants' knowledge of radiation protection aligned with the legislated guidelines, limited internalising of the knowledge resulted in compliance being a personal choice. Participants reflected on their insouciant attitude and observed a similar attitude in their radiographer colleagues. Patient and work-related impediments were identified to contribute to radiation protection compliance. Strategies to further foster compliance were suggested. Implications for practice: Understanding the reasons for radiographers' choice in radiation protection will allow the development of strategies that foster optimum application of radiation protection practises. Developing a radiation protection culture that enhances personal compliance supported by education and evidence should be considered.

“…Thus, if the prescribed hygiene measures are not adhered to, the ASM can act therefore as a superspreader. Since hygienically cleaning the ASM after each use significantly affects the workflow, digital side markers (DSM) could therefore act as an alternative 13 . While DSM were already in common use, they were only considered recently during the COVID-19 pandemic as good practice.…”

An important quality criterion for radiographs is the correct anatomical side marking. A deep neural network is evaluated to predict the correct anatomical side in radiographs of the knee acquired in anterior–posterior direction. In this retrospective study, a ResNet-34 network was trained on 2892 radiographs from 2540 patients to predict the anatomical side of knees in radiographs. The network was evaluated in an internal validation cohort of 932 radiographs of 816 patients and in an external validation cohort of 490 radiographs from 462 patients. The network showed an accuracy of 99.8% and 99.9% on the internal and external validation cohort, respectively, which is comparable to the accuracy of radiographers. Anatomical side in radiographs of the knee in anterior–posterior direction can be deduced from radiographs with high accuracy using deep learning.
