The Radiological Physics Division

The Radiological Physics Division (RPD) was initially established in July 2002 as the Division of Medical Imaging Physics (DMIP) with the recruitment of Benjamin Tsui and his 14 associates — in 2018, George Sgouros became director of the division.  It was rebranded as the Radiological Physics Division to expand its mission beyond imaging so that all of radiological physics, including radionuclide therapy is encompassed.

Mission Statements

  • Conduct state-of-the-art research in medical imaging physics, especially in the areas of nuclear medicine, including PET and SPECT, and X-ray imaging, including CT.
  • Establish a graduate degree program in medical imaging physics within the Department of Radiology and Radiological Science.
  • Provide physics education to residents, fellows and technologists.
  • Provide clinical physics support to various clinical divisions of the Department of Radiology and Radiological Science.      

Our Research

Education Programs

Master’s in Medical Physics

The program is designed for full-time students who wish to pursue a career as a medical physicist either as a researcher, as a certified clinical professional, or in industry. The program will require successful completion of a minimum of 38 credits for Master’s degree and completion of a research thesis (in conjunction with one or more of the faculty). Full-time master’s students will complete the program in two years.

Prospective Postdocs

The Division employs a number of postdoctoral fellows working on research projects funded by research grants and contracts. Most of the research projects require significant technical skills and knowledge in physics, mathematics, computer science, radiobiology, dosimetry, engineering and/or medical physics. Excellent English language and communication skills are also essential. Applicants with previous skills directly related to the research projects of interest are strongly preferred.

Postdoctoral Fellowship applicants should contact the division faculty staff directly for availability in his/her lab. Previous postdoctoral fellows have gone on to careers in academia, clinical medical physics, and industry.
