Execute planning for intracavitary and interstitial brachytherapy procedures. Supervise, perform, or assist in the process of producing moulds, casts, and other immobilization devices for accurate treatment delivery. Use imaging modalities such as CT scans alone or in combination with MRI or PET scans to create conventional or IMRT treatment plans that enable us to give higher doses of radiation to a tumor while lowering the doses to the sensitive structures around it. Perform calculations for the accurate delivery of the Radiation Oncologist's prescribed dose, document pertinent information in the patient record, and verify the mathematical accuracy of all calculations using a system established by the Medical Physicist. Perform or assist in the application of specific methods of radiation measurement as directed by the Medical Physicist. Provide technical and physics support to the Medical Physicist; this support could be in radiation protection, qualitative machine calibrations, and quality assurance of the radiation oncology equipment. Assist in the clinical education of radiation oncology residents, radiation therapy students, or medical dosimetry students. Understand the technical aspects of radiation oncology and medical physics to meticulously derive computerized treatment plans and communicate these aspects to the Radiation Oncologist for plan approval and to the Radiation Therapist for plan implementation. Perform routine duties independent of supervision, consulting with the Radiation Oncologist and Medical Physicist as required. Interpret and execute treatment plans as defined in relevant treatment protocols. Work Schedule: Mon - Fri, 8:00am to 4:30pm. Telework: Ad-hoc. Virtual: This is not a virtual position.
