IMRT patient QA
Test IMRT plan delivery versus TPS calculation in the treatment gantry position:
- Replace patient 3D model with water phantom and calculate dose distribution per field separately
- Calculate verification plan using YOUR CLINICAL dose calculation algorithm
- DICOM export dose plane at dmax as a reference matrix
- Deliver the IMRT plan normal way while acquiring integrated image for each field
- Compare calculated versus acquired dose matrices using Epiqa
Example of some evaluation tools
- Profiles comparison
- Point evaluation – dose difference, gamma
- Results histogram and statistics
- Flexible definition of local or global gamma criteria
- Results can be printed in a protocol
