Summary
Accurate target volume delineation is crucial for conformal radiotherapy. This presentation covers challenges in defining gross tumor (GTV) and clinical target volumes (CTV), referencing ICRU 62 guidelines and inter-observer variability.
Area of Science:
- Medical Physics
- Radiation Oncology
- Radiotherapy Planning
Context:
- Accurate target volume delineation is a critical step in conformal radiotherapy planning.
- Variability in defining gross tumor volume (GTV) and clinical target volume (CTV) poses challenges.
- The International Commission on Radiation Units and Measurements (ICRU) Report 62 provides recommendations for target volume representation.
Purpose:
- To discuss the main difficulties encountered in evaluating GTV and CTV.
- To present the key recommendations for target volume representation based on ICRU 62.
- To highlight observed differences in inter-observer volume comparisons.
Summary:
- This presentation addresses the complexities of target volume delineation in conformal radiotherapy.
- It explores challenges in defining GTV and CTV, referencing ICRU 62 guidelines.
