Physics Residency Program: Resources

Faculty and Staff

The faculty of the Radiation Oncology Physics Residency Program represents the foundation and strength of our Program. All of our faculty have appointments at Washington University and provide clinical support to the Barnes-Jewish Hospital radiation oncology clinic. The faculty has a broad teaching expertise and access to a wealth of clinical physics equipment and training resources.

The faculty and staff interact regularly through (1) physics faculty meetings, (2) seminars, (3) case conferences, (4) quarterly departmental faculty meetings, (5) hospital or medical school committee meetings, (6) Physics Residency Committee meetings, and (7) annual retreats of the Department’s faculty.

The faculty‑resident interactions occur at (1) clinical physics rotations, (2) classroom environment, (3) seminars, (4) private appointments to discuss the designated comprehensions, clinical rotation, or personal problems, and (5) social activities (Division parties, etc.). In addition to the routine meetings, the residents also have access to the Program Director and Division Director to discuss sensitive personal or training problems. We feel there is relatively open communications between residents, faculty, Program Director, and the Division Director.

For an estimated Program capacity of 6 residents and a planned 12 radiation oncology physics faculty, our resident to faculty ratio is approximately 1:2.

The typical financial burdens of a physics resident based on actual data provided by the residents are as follows:


Resident A

Resident B




Car Insurance



Health Insurance


















Resident Funding

Effective July 1, 2014, the following funding levels are in effect for physics residents:

•  1st year Physics Resident:         $48,000

•  2nd year Physics Resident:        $49,200

In addition to direct compensation, physics residents are afforded benefits consistent with other hospital employees including medical and dental insurance, paid vacation and holiday benefits (3 weeks), 5 paid meeting and/or interview days in their second year, sick pay benefits, and disability insurance.  The expense of these benefits varies and is shared between the physics resident and Barnes-Jewish Hospital.
The residents are funded up to $1,200 so each attends a national meeting in their second year.  At the beginning of the second year, the resident receives a book allowance of $500 to be spent within 90 days.

Resident Offices, Classrooms, and Conference Rooms

The Physics Residency Program provides office space for each resident in the program. The Resident Office, for medical and physics residents, is currently located in Siteman Cancer Center’s Radiation Oncology Department.  The room is allocated for the capacity for 6 physics residents.  Residents are provided a cubicle including a desk, file cabinet and bookcase, computer terminal connected to LAN, telephone access, and standard office supplies. Residents have access to departmental copying equipment. The Physics residents are also provided with a library account for electronic access to journals and journal searches (Medline, OVID).

Ample space is available for resident advisory meetings, didactic lectures, exams, seminars, and oral examinations. Three meeting rooms/classrooms are in the department.  They each contain whiteboards, LCD video projectors, and computer or computer connections for LCD projection.  Additional conference rooms are available in the SCC if needed.

Clinical Facilities, Laboratories, and Shops

The residents have access to a myriad of laboratory and shop facilities including: (1) a dosimetry instrumentation lab in the physics research area; (2) a brachytherapy lab in the Brachytherapy Suite; and (3) other research labs and offices in the Clinical Science Research Building.  Residents submit work orders to a campus machine shop as required.  In all, the availability of dosimetry and clinical treatment areas and equipment is more than adequate to serve the needs of the residency training program.  Procedures are in place that (1) allow the resident reasonable access time to clinical equipment, (2) provide residents sufficient training and technical support to ensure safe and proper use of equipment, and (3) to ensure equipment is left in the proper state for clinical use.

Treatment planning and external beam delivery equipment utilized in the training program include 7 Varian (incl. 2 Trilogy units and 2 True Beam), Gamma Knife planning and delivery, a therapeutic x-ray unit, 2 Philips Brilliance CT-simulators (16-slice-large and 64-slice-small “bore”), a 3.2T MRI simulator capable of HiFu, 26 Pinnacle TP workstations, and Varian Eclipse workstations.  We have the world’s 1st compact, single room proton machine from Mevion Medical Systems.  Testing began clinical start up in December of 2013.  In addition we began treatment with the world’s first combination real-time MRI and IMRT system from ViewRay.  The founder and Chief Scientific Officer is a former resident.  Specialized equipment and features include the DMLC-IMRT delivery, linac and Gamma Knife stereotactic radio-surgery/therapy, and image guidance provided by on-board x-ray imaging, portal photon imaging, video surface imaging, internal transponders for tracking, and kV-CT systems.  Clinical rotations are also provided within our HDR, LDR, prostate seed, and radiopharmaceutical program, including image guided interstitial, intracavitary and surface implant planning and delivery.
