Medical Physics Assistant

Job Summary:

The Radiation Oncology Physics Section at the University of Wisconsin-Madison School of Medicine and Public Health, Department of Human Oncology, is seeking a Medical Physics Assistant (MPA) to engage in radiation oncology physics activities. The Radiation Oncology Physics section currently employs 24 physicists, 6 medical physics residents, and 2 MPAs across the enterprise. The successful candidate will assist with quality assurance measurements on external beam treatment delivery systems, CT and MR imaging systems, and brachytherapy equipment. They will develop automated reports and dashboards to aggregate quality assurance results and assist with the integration of computational tools into clinical and research workflows. They will assist data curation and management to support clinical research and trials activities.

The MPA shall function as an extender to the medical physics group within the Department, with supervision requirements and a scope of work aligned with guidelines established by the American Association of Physicists in Medicine (AAPM) Medical Physics Practice Guidelines Report 10a and AAPM Policy AP-131-A. Medical physics tasks performed by the MPA shall be reviewed and co-signed by a Qualified Medical Physicist.

The primary location for MPA activities will occur at the UW Health University Hospital location. The UW Health University campus currently includes a Viewray MRidian Linac with daily online adaptive radiation therapy, three Varian TrueBeams (one STx), an AccuRay Tomotherapy HDA, and two Elekta Flexitron Remote Afterloaders. We offer a broad range of special procedures, including SRS/SBRT, TBI, TSE, and brachytherapy for a wide range of treatment sites (e.g. GYN, breast, prostate) with MRI-guided planning and BodyTom CT for image verification. Advanced simulation capabilities are routinely integrated into clinical practice including Siemens dual-energy computed tomography and 1.5 T GE MR-simulator units. Automated planning/scripting is employed via robust use of RayStation coupled with MIM.

Additional support activities may be expected UW Health Eastpark Medical Center location, which is part of our dual-hub model located on Madison's east side. The 469,000 square foot state-of-the-art facility opened in October, 2024, initially offering photon treatments with two Varian TrueBeams, a Varian Edge, and an Elekta Flexitron Remote Afterloader coupled with Siemens multi-energy CT on rails, as well as dedicated CT and MR simulators. While beyond the scope of the present job description, proton therapy via a Hitachi gantry room and fixed beam room with first-of-kind upright patient positioning system will be offered at the Eastpark location later in 2026.
