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
- Consider specific insights you hope to gain regarding the practical implementation of quality assurance in medical imaging.
- Think about your current knowledge of MRI and hybrid-modality scanner performance metrics.
- Anticipate learning about the materials and design considerations for effective quality assurance phantoms.
- Consider the challenges and practicalities of designing a functional and relevant phantom.
- Discuss the specific scanner type (MRI or hybrid) and the aspects of quality assessment to focus on with your training officer.
- Research existing literature and guidelines on quality assurance phantoms for medical imaging.
- Investigate the properties of different materials that can be used in phantom construction.
- Consider the practical aspects of manufacturing and using the designed phantom.
- Reflect on your current understanding of quality assurance procedures in medical imaging.
In action
- Pay attention to your actions. How are you approaching the research and design of the phantom? Why are you doing it this way?
- What decisions are you making as you select the materials, dimensions, and features of the phantom based on the quality assessment parameters?
- What aspects of understanding the principles of quality assessment and phantom design feel intuitive, and what requires more conscious effort?
- How effective are your actions in researching relevant quality assessment parameters and designing a suitable phantom?
- What challenges are you facing in balancing the requirements for different quality tests or considering the practical aspects of phantom construction?
- What can you learn about the principles and practicalities of quality assessment in MRI or hybrid-modality imaging as it unfolds?
- How does this activity connect to your knowledge of image quality metrics and scanner performance?
- Are there alternative designs or materials you could be considering for the phantom?
- What support or guidance might you need in this moment to understand specific quality assessment requirements or fabrication techniques?
- Are you systematically considering the different aspects of scanner performance that the phantom should assess?
On action
- What existing MRI or hybrid-modality phantoms are used for quality assessment?
- What parameters or image quality characteristics are these phantoms designed to evaluate?
- What considerations did you take into account when designing your phantom (e.g., materials, dimensions, features)?
- What did you learn about the principles of quality assessment in MRI or hybrid imaging?
- How did this research and design process enhance your understanding of the requirements for effective quality control phantoms?
- What challenges did you encounter in the design process?
- How will this knowledge inform your understanding of quality assurance procedures in your future practice?
- What further learning could you undertake in the area of medical imaging quality assurance?
- What support or resources might you need to further develop your understanding in this area?
Beyond action
- Reflect on the process of researching and designing your quality assessment phantom. What were the key considerations and challenges you encountered?
- Have you had the opportunity to use or see phantoms being used for quality assessment of MRI or hybrid scanners? How did the design principles you considered compare to those of existing phantoms?
- Consider if your understanding of MRI physics and quality assurance procedures has evolved, and how this might influence your phantom design if you were to undertake this task again.
- Has this activity deepened your understanding of the principles and importance of quality assessment in MRI and hybrid imaging?
- Has your knowledge of the physical parameters that need to be assessed (e.g., spatial resolution, signal-to-noise ratio) been enhanced by the design process?
- How will a thorough understanding of the requirements for quality assessment phantoms be valuable in future roles involving quality assurance management or research and development of imaging technology?
- What further research into advanced phantom designs or specific quality assessment methodologies would you be interested in undertaking?
