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.
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).
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.
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.
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.
随着近年来国际上技术的进步，剂量递增现象现在已经成为诊断放射学中一个广泛认可的概念。然而，对于准备进入放射科专业的放射学学生来说，这一现象仍然研究不足。有鉴于此，本研究探讨了本科放射技师对剂量递增现象的看法。
本研究采用扎根理论的方法。这种定性方法旨在揭示澳大利亚一所高等教育机构的发现。招募了 6 名学生参加半结构化访谈。这使我们能够探索以前未被发现的数据，从而在临床和学术环境中构建原始理论。采用的数据分析是恒定比较分析（CCA）。
从定性数据集得出了一些见解。例如，放射技师对“剂量递增”一词的理解以及在临床环境中导致剂量递增的决策都被记录下来。这进一步得到了图像评估的支持，以确定适当的曝光因素选择，并对毕业后作为诊断放射技师的未来影响。研究结果确定了临床和学术环境中都需要满足的一些重要学习需求和行动，这可能有助于培养良好的 X 射线使用。
本文通过肯定围绕最佳曝光选择和已知现象“剂量递增”的一些挑战，得出结论。此外，本研究还确定了在临床环境中学习和教学的重要性，因为所学的行为会导致次优的实践。
本研究通过在学术和临床背景下为放射技师学生对剂量递增的知识和理解提供独特的视角，扩展了现有证据基础。预计本文将帮助从业者和教育者更好地理解临床环境中潜在的剂量递增实例。
