Deep Learning for MR-only radiotherapy treatment workflow

Post-operative stereotactic radiotherapy to the resection cavity is standard of care for patients that underwent neurosurgery for brain cancer. Current image-guided radiotherapy requires acquisition of MR scans that allow manual delineation of tumor target and organs at risk (OARs), and thereafter, acquisition of a CT scan for radiotherapy dose planning and patient position verification at the linear accelerator during treatment. In this project we will develop image analysis algorithms to allow fast delineation of tumor target and OARs. Moreover, we will develop algorithms for the synthesis of CT scan to allow MR-only MRI workflow for radiotherapy interventions shortly after neurosurgical procedures.
