Reflective practice guidance
The guidance below is provided to support reflection at different time points, providing you with questions to aid you to reflect for this training activity. They are provided for guidance and should not be considered as a mandatory checklist. Trainees should not be expected to provide answers to each of the guidance questions listed.
Before action
- What are the intended outcomes of the training activity?
- How will you ensure you can effectively analyse the relationship between patient radiation dose and the resulting image quality for the specific clinical task you have chosen?
- In what ways will this activity help you identify specific opportunities to optimise imaging protocols so that patient dose is reduced without compromising diagnostic image quality?
- What do you anticipate you will learn from the experience?
- What are the key parameters influencing patient dose in x-ray imaging that you need to consider most carefully for this specific task?
- How will you evaluate the various technical factors contributing to diagnostic image quality, such as spatial resolution, contrast, and noise, during your review?
- What specific principles and techniques of dose optimisation do you anticipate learning and applying through this activity?
- How will you develop the professional skill of balancing the competing demands of maintaining the lowest possible radiation dose versus the need for high-quality diagnostic images for this clinical indication?
- What actions will you take in preparation for the experience?
- How will you structure your discussion with your Training Officer to ensure you have a clear and comprehensive understanding of the specific imaging task you will be reviewing?
- Which specific literature, research papers, and national guidelines on dose optimisation for this particular imaging task will you review to ensure your work is evidence-based?
- What are the typical dose levels and image quality requirements for this specific examination, and how will you use them as benchmarks for your recommendations?
- How do you feel about your role in contributing to radiation protection and the direct improvement of clinical image quality?
- Does acknowledging any feelings of uncertainty regarding the balance of dose versus quality help you focus your preparation on the specific technical parameters you need to master?
In action
- What specific imaging task are you currently focusing on?
- What are the clinical requirements for image quality for this task?
- How are you analysing the available data on patient dose and image quality for this task? What parameters are you examining?
- What potential optimisation strategies are you considering, and what is your rationale for these?
- Which aspects of this review process feel more familiar based on your understanding of patient dosimetry and image quality, and which require more critical evaluation and synthesis of information?
- How effectively are you able to link the patient dose data to the achieved image quality for this specific task?
- What challenges are you encountering in identifying potential trade-offs between dose and image quality or in determining the optimal balance?
- What are you learning about the practical application of optimisation principles in diagnostic radiology?
- How does this activity connect to your understanding of patient dose audits and the principles of radiation protection?
- Are there alternative optimisation approaches you should consider based on best practice or national guidelines?
- Do you need to gather additional data or consult with experienced colleagues to inform your recommendations?
- Are your recommendations practical and implementable within the clinical setting, considering the available equipment and protocols?
On action
- What specific imaging task was considered?
- What data on patient dose and image quality was reviewed?
- What were the current dose levels and image quality parameters for the selected task?
- What potential areas for optimisation were identified?
- What specific recommendations were made to optimise the balance between patient dose and image quality?
- What factors were considered when formulating these recommendations?
- What did you learn about how to assess patient dose and image quality for a specific imaging task?

- What did you learn about how to formulate evidence-based recommendations for dose reduction while maintaining diagnostic image quality.
- How will you approach future optimisation tasks?
- What data will you need to collect and analyse?
- How will you ensure that your recommendations are practical and effective?
Beyond action
- Have you reviewed patient dose and image quality for other imaging tasks since this training activity?
- How has your approach to identifying optimisation opportunities evolved?
- Consider the specific imaging task you reviewed. Have you revisited the data or the recommendations you made in light of subsequent learning or changes in protocols?
- Have you discussed optimisation strategies with radiographers or radiologists in other contexts (e.g., optimisation meetings)?
- Did these discussions provide further insights?
- How has this activity enhanced your understanding of the relationship between patient dose and image quality and the principles of optimisation?
- Have you been able to apply your knowledge of optimisation strategies to other imaging protocols or clinical situations?
- Consider how this experience has influenced your awareness of the importance of balancing diagnostic information with radiation dose.
- Identify how your skills in reviewing patient dose and image quality and making optimisation recommendations will be crucial for ensuring best practice in radiation protection in your future role.
