Training activity information

Details

Process image data and generate a treatment plan for a patient having undergone a 4DCT scan

Type

Developmental training activity (DTA)

Evidence requirements

Evidence the activity has been undertaken by the trainee​.

Reflection on the activity at one or more time points after the event including learning from the activity and/or areas of the trainees practice for development.

An action plan to implement learning and/or to address skills or knowledge gaps identified.

Considerations

  • 4DCT scan parameters and patient considerations
  • ICT considerations
  • Advantages and limitations compared to 3DCT generated treatment plans
  • Local protocol, for handling and interpreting 4D CT data (e.g. intensity projection, visualisation, outlining and dose calculation)
  • Geometric and dosimetric uncertainties
  • Individualised treatment planning, including patient tolerance and suitability for treatment
  • Patient centred care and support
  • Value of different motion management approaches
  • Clinical appropriateness of the treatment plan
  • Image modality and registration considerations

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 principles of 4DCT?
  • How is this data used in treatment planning?
  • What are the relevant treatment planning system tools and protocols?
  • What challenges might you face in image processing or plan generation?
  • How do you feel about generating a treatment plan using this data?

In action

  • What steps are you taking to segment the target volume and organs at risk across the respiratory phases?
  • How are you accounting for motion in the treatment planning process?
  • What initial planning strategies are you considering?
  • Which aspects of 4DCT processing and planning require careful attention to detail?
  • Are you able to accurately segment the relevant structures across all phases of the 4DCT?
  • Is the treatment planning system effectively incorporating the motion information?
  • Are the initial plan parameters (e.g., beam angles, dose distribution) looking reasonable?
  • If you encounter challenges with image registration or target volume definition due to motion, what alternative techniques or strategies are you considering?
  • Are you consulting with colleagues experienced in 4DCT planning? Are you adjusting the planning objectives to account for motion uncertainties?

On action

  • What were the steps involved in processing the 4DCT data? How was motion incorporated into the treatment planning process? What planning techniques and tools were used? What were the challenges in generating a plan that accounted for motion?
  • What did you learn about your skills in image processing techniques specific to 4DCT, your ability to utilise treatment planning software effectively, and your understanding of how motion management influences treatment planning? Are there specific software functions or image analysis techniques you need to explore further?
  • How will this improve your skills in processing 4DCT data and generating treatment plans for patients with motion? How will this enhance your understanding of the challenges and solutions in motion management? What further training or experience would be valuable in advanced treatment planning techniques?

Beyond action

  • Revisiting your reflections, how has your understanding of 4DCT and its role in treatment planning changed over time?
  • How has this experience of generating a treatment plan using 4DCT data influenced your approach to other treatment planning tasks, particularly for patients with respiratory motion?
  • Can you identify specific skills developed during this activity (e.g., image processing, contouring) that you have applied in other areas of your training?
  • How has this experience since contributed to your ability to optimise treatment plans for patients requiring advanced imaging techniques?
