Hera for IMRT QA
Hera for IMRT QA is designed to compare the calculation and delivery of sliding window or step-and-shoot IMRT fields, in particular for pre-treatment QA.
It includes comparison of the acquired Portal Vision integrated images with the calculated IMRT fields 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. Each field is delivered while acquiring integrated image at the treatment gantry angle. Analysis workspace supports dose difference, gamma analysis using user selectable ROI.
