Therapeutic Medical Physics Residency

About the Program:

The Therapeutic Medical Physics Residency program at the Department of Radiation Medicine in LLUMC offers clinical training in a broad range of categories. The medical physics residency is a 2 year program designed for individuals with a MS or a PhD from a CAMPEP accredited Medical Physics Graduate program.  The objective of a medical physics residency training program is to educate and train medical physicists to a level of competency sufficient for independent, professional practice in their specified subfield of medical physics.

5 PhD Physicists
4 MS Physicists
6 Dosimetrists
8 Radiation Oncologists


 We have 4 linear accelerators, a dedicated CT scanner, a PET-CTunit, a patient immobilization facility, a device manufacturing facility, and a physics/dosimetry lab. MRI center and nuclear medicine facilities are in the immediate vicinity of our department. Loma Linda is also home to world’s first hospital based Proton therapy center, with three isocentric gantries, two fixed beam-lines, and a research room with three additional fixed beam-lines. We also offer Radiation therapy at satellite facilities in Highland Springs,CA (about 25 miles from LLUMC) and Murrieta,CA ( about 40 miles from LLUMC). Both these facilities have one LINAC each.

We treat many types of cancers with both x-rays and protons. We perform 3D-CRT, IMRT, SRS, SBRT, TBI, and ocular treatments. We also offer LDR Brachytherapy and Sr-90 ophthalmic treatment for Pterygium. In addition, we have signed an agreement with Long Beach Memorial Medical Center, under which the Physics residents will spend a two- 6 week clinical rotation there to receive clinical training in Tomotherapy and HDR procedures.

In addition to residency program in medical physics, we also have a residency program in radiation oncology, a radiation therapy technology program and a medical dosimetry program.

Application and Review Process:

Interested Applicants must apply through the Medical Physics Residency Application Program (MP-RAP) and register with the Medical Physics Residency Matching Program (MedPhys Match).  All applications will be considered by an admission committee. The applicants will be evaluated initially based on the submitted application material. The top ranking candidates will be invited for an on-site interview. Following the on-site interview, a rank list will be prepared and submitted to the MedPhys Match for matching.
