Digital radiographers: Dose creep and the next generation

Research output: ThesisHonours Thesis


Dose creep is a well-documented phenomenon that has been recognised throughout the evolution of imaging technologies. It is important to consider the impact the next generation of radiographers will have on this phenomenon. Aims: The aim of this research was to gain information about student radiographers’ understanding of ‘dose creep’. Specifically, gathering insights into the educational and practical experiences influencing the manipulation of exposures using DR technology in general radiography.
Methods: Data collection was completed with the use of semi-structured interviews encompassing a qualitative Grounded Theory approach, which entails the disciplined inquiry of personal views and experiences of individuals amidst their social environment/s. It incorporated a systematic approach that allows theories to develop directly driven by data. This approach enhanced research surrounding the topic of dose creep, by giving an in-depth interpretation of perceptions within the student population, in what previously has largely been explored through positivistic paradigms.
Results: The results state that students are aware of the importance of radiation exposure to patients, however have limited knowledge on the phenomenon of dose creep and the manipulation of exposure parameters on digital systems. Conclusion: This study identifies students’ lack of evidence based knowledge and practice surrounding the manipulation of exposure parameters in DR in the general x-ray department. It also concludes that students are more worried about repeat images adding to patient’s radiation exposure than excess dose on non-repeated images.
Recommendations: further study into the process of manipulating exposures and the monitoring of exposure indices in the clinical setting would be advantageous.
