Medical Radiation Physicist, M.S. (Certified)



US-OR-GRESHAM

Job ID: 25-41829
Type: Regular Full-Time
Mount Hood Medical Center campus

Overview

Legacy Health System, which operates three radiation oncology facilities in Portland, Oregon, and Vancouver, Washington, has an opening for a full time, board certified, Radiation Oncology Medical Physicist to backfill for a retirement. The primary focus will be on external beam treatments at the single LINAC facility at Mount Hood Medical Center in Gresham Oregon but will also include participation in programs at the downtown Portland and Salmon Creek facilities both of which are within 20 miles of Mount Hood Medical Center. The preferred candidate will have experience with all facets of an external beam facility including LINAC, CT, and surface guidance, and a history of collaboration with dosimetrists, therapists, and physicians. Currently, equipment that is common to all sites incudes: Raystation TPS v11b, 4D GE CT and Elekta IGRT LINAC. The Salmon Creek facility also provides SGRT via Vision RT. The downtown Portland facility has active programs in Gamma Knife radiosurgery (120 patients/year), high and low dose rate brachytherapy (125 patients/year), IORT and Eye Plaque. The external beam practices involve the extensive use of VMAT and SBRT, and patients frequently receive combined therapies with brachytherapy and Gamma Knife SRS. This position will primarily work in an unsupervised capacity. The physicist will join a team, which currently includes four physicists, six physicians and four dosimetrists. Each satellite facility has a primary physicist, and the remaining physicists are based at the downtown facility. All physicists assist each other at the different worksites, providing cross-cover as required, and there is an opportunity to support and receive Gamma Knife and HDR specific training and credentialling. This position offers opportunities and professional challenges associated with innovative and procedure focused practices, with the feel of a community based medical center, access to the vibrant city of Portland and the amazing outdoors of the Pacific Northwest's mountains and coast. The Medical Physicist is responsible for computations, measurements and communication as necessary to ensure accurate delivery of radiation therapy treatments as prescribed by the Radiation Oncologist. A Medical Physicist must fully understand the operations, qualities and necessary safety requirements of all treatment and treatment planning equipment. Legacy Mount Hood Medical Center is East County's full-service hospital, always expanding to meet the community's growing needs and offering an award-winning patient experience delivered with a personal touch. We offer advanced imaging, a modern emergency department, a welcoming family birth center, surgical services, intensive care, cancer care, gastroenterology and more.
