Physics Residency Program

Radiation Oncology Physics Residency

Training for the CAMPEP-accredited Physics Residency Program involves full participation of the physics resident in the clinical and research components of radiation oncology physics. Residents are trained under the supervision of experienced radiation oncology physicists. Areas of training include dosimetry, treatment planning, treatment aid design and fabrication, brachytherapy, radiation safety, radiation machine calibration, imaging, special procedures, and quality assurance. Throughout the training rotations, opportunities are available in various areas of research.

The knowledge obtained from participating in the Physics Residency Program will prepare the resident for certification in the specialty of Therapeutic Radiological Physics by the American Board of Radiology. The skills acquired from the hands-on training will prepare the resident for a career as a clinical radiation oncology physicist capable of independent practice.

Physics Section Overview

The Medical Physics Section of the Department of Radiation Oncology at the Medical College of Wisconsin consists of 17 physicists, 10 dosimetrists, 8 postdoctoral research fellows, 4 physics residents and other supporting staff. X. Allen Li, PhD, is the Chief Physicist. The physics faculty, staff and residents are employees of the Medical College of Wisconsin while the dosimetrists are employed by Froedtert Health.

Clinical activities performed by the Physics Section include machine QA and treatment planning as well as development, implementation, and support for specific procedures such as imaging, image-guided RT (IGRT), intensity modulated RT (IMRT), stereotactic body RT (SBRT), 4D/gated RT, brachytherapy, and TomoTherapy. Research activities include developing strategies and tools for adaptive RT, biological/functional image-guided RT, RT outcome modeling, biologically based treatment planning, and strategies to manage respiratory motion.
