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
- Role of physics support in clinical situations
- Professionalism and behaviour with patients
- Effective communication with the multidisciplinary team
- Patient suitability for treatment
- Physics of electron interactions
- Use of margins in electron treatments
- Choice of energy and plan design
- Principles of manual dose calculations
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 common clinical applications of electron beam therapy?
- How does the choice of electron energy and applicator size affect penetration and dose distribution for different anatomical sites?
- What methods are used for patient dose calculations in electron therapy?
- What patient and treatment-related information is required to provide informed advice and perform accurate dose calculations?
- What guidelines or protocols are available for electron treatment planning and delivery?
- What factors might complicate the selection of appropriate electron beam parameters?
In action
- As you assess the patient’s anatomy, are you visualising the expected electron beam range and isodose curves?
- How are you selecting the appropriate electron energy to treat the target volume effectively while sparing deeper tissues?
- When determining treatment delivery parameters, are you considering factors like skin contour irregularities and the need for bolus?
- Are you applying any correction factors in your dose calculations?
- When advising on electron treatments, are you clearly communicating the rationale behind your choices to the team?
- Are you aware of the potential for skin reactions or other electron-specific side effects?
On action
- What anatomical sites were you advising on for electron treatments? What factors did you consider when determining suitable electron energies and applicator sizes? How did you account for patient geometry and tissue inhomogeneities in your recommendations and dose calculations?
- What are the typical clinical indications for electron treatments at various anatomical sites? How does the finite range of electron beams make them suitable for treating superficial targets while sparing deeper tissues? What are important considerations for electron treatment planning and delivery, such as skin contour irregularities and the use of bolus? How did you communicate your advice and the rationale behind your recommendations to the multidisciplinary team?
- How will you enhance your understanding of electron beam physics and their clinical applications? What further practice will you undertake in selecting appropriate electron energies and performing accurate dose calculations? How will you ensure you provide comprehensive and clinically relevant advice on electron treatments in the future?
Beyond action
- Reflecting on your experience advising on electron treatments, have you revisited your initial understanding of electron beam characteristics and their clinical application?
- How has this training activity since influenced your approach to understanding and advising on the use of electron beams in different clinical situations?
- How has your knowledge of electron treatments and dose calculations since contributed to your ability to provide specialist advice on superficial radiotherapy and participate in treatment planning?
