Artemis for VMAT

Artemis for VMAT QA supports analysis of any VMAT dose distribution calculation and its delivery, in particular for pre-treatment QA.

It compares acquired EPID integrated image over the whole arc with the calculated dose distribution using dose to water conversion. Reference dose matrix is calculated to water phantom at any depth using the same calculation algorithm as for patient plan and resetting all calculated segments to zero gantry angle. VMAT is delivered under normal treatment conditions while acquiring integrated image. Analysis workspace supports dose difference, gamma analysis using user selectable ROI.

Module Artemis offers functionality to verify machine performance (Clinac and MLC) and patient plan QA:
