Our Program

Dr Charles Thomas and Dr Nima Nabavizadeh

The Radiation Oncology Residency Program at OHSU is located in the Department of Radiation Medicine, occupying the fourth floor of Kohler Pavilion on the Marquam Hill campus. The department serves the entire campus including Doernbecher Pediatric Hospital, the VA Portland Health Care System and the Center for Health and Healing

The mission of the program is to cultivate outstanding radiation oncologists equipped with the knowledge and skills to build productive and fulfilling careers as clinicians, educators, researchers and advocates. Training is provided by a combination of supervised clinical experiences, seminars, lectures and research assignments designed to expand the trainee’s clinical skills and to provide a broad scientific basis for growth.  The trainee’s rotation to various segments of the program follow a pattern of progressively increasing responsibility throughout the four year post internship training. We also offer core curriculum instruction in radiation biology and physics. Clinical rotations will lead to experience with pediatric, thoracic, gastrointestinal, genitourinary, lymphoma, head and neck, soft tissue, breast and central nervous system malignancies.

The department utilizes over 17,000 square feet of space and is staffed by 14 full-time radiation oncologists, 13 full-time physicists and a full complement of clinical personnel including radiation therapists and dosimetrists.  Two Elekta Versa HD linear accelerators, a Varian TrueBeam linear accelerator, and a Tomotherapy HD unit are used to provide external beam electron and photon radiotherapy.  Image guidance consists of onboard-imagers at all LINACs with both kV-kV, cone beam CT and MVCT capabilities. Calypso radio frequency beacon localization, BrainLab ExacTrac fluoroscopy and optical guidance imaging is utilized as part of a full service image guidance program. We have a Philips Brilliance BigBore CT scanner with respiratory gating capabilities for 4D CT based simulation. We also have available a 4D PET CT scanner with in our department that can be utilized for biologic functional treatment planning.  External beam treatment systems consists of Eclipse, Pinnacle, Monaco and BrainLab Iplan system. These systems are used for CT-based 3D treatment planning, inverse modulated radiation therapy (IMRT), volumetric-modulated arc radiotherapy (VMAT), dynamic conformal arc therapy, stereotactic body radiotherapy, Linac-based radiosurgery, total body irradiation and total skin electron-beam therapy. The department uses high-dose rate (HDR) Iridium-192 for the majority of its brachytherapy needs. Radioactive Iodine-125 seeds and Iridium-192 are ordered for individual cases as needed.  We have an active I-125 eye plaque brachytherapy program for choroidal melanomas with the Casey Eye Institute.  We have a interstitial brachytherapy program which includes therapy for prostate cancer, soft tissue sarcoma and even for lung cancers.

We strive to provide training in a diverse, inclusive, collegial educational environment where each resident's wellbeing and professional development are among our utmost priorities and in alignment with the University's mission of healing, teaching and discovery.
