Summary
This study details the creation of specialized breast and chest wall phantoms for radiotherapy audits. These phantoms ensure accurate treatment planning and dose assessment in clinical settings.
Area of Science:
- Medical Physics
- Radiotherapy
- Medical Imaging
Background:
- Radiotherapy planning requires accurate phantoms for quality assurance.
- The START trial necessitates specific phantoms for breast and chest wall treatments.
Purpose of the Study:
- To design and construct specialized breast and chest wall phantoms for the START trial.
- To evaluate the accuracy of radiotherapy planning and dose assessment through phantom audits.
Main Methods:
- Development of two-dimensional phantoms for initial audit visits.
- Construction of a water-filled three-dimensional phantom for off-axis dosimetry.
- Creation of a phantom to assess dose at field junctions.
Main Results:
- Four phantoms were manufactured, including 2D and 3D designs.
- Phantoms facilitate assessment of planning accuracy and dose distribution.
- The phantoms are integral to the START trial's audit process.
Conclusions:
- The designed phantoms address complex radiotherapy planning and dosimetry challenges.
- These phantoms are crucial for ensuring accurate and safe radiotherapy delivery.
- The manufacturing process supports the development of essential quality assurance tools.
