Medical Physicists work within a team consisting of radiation oncologists, nurses, radiation therapists and dosimetrists to deliver safe and effective radiation treatment for cancer care.  Medical Physicist duties are listed below.


Medical Physics Team at JCC

Treatment Planning

Treatment objectives devised by the radiation oncologist are implemented into a treatment plan by the dosimetrist and Medical Physicist.  The former uses well established planning principles to construct and model an optimized plan in the treatment planning computer.  A Medical Physicist collaborates with the dosimetrist and reviews the final plan to ensure the accuracy of dose calculations and that the plan satisfies the prescribed treatment objectives.

Quality Assurance
Medical Physicists and Physics Assistants work to measure and characterize the performance of imaging, treatment and dose monitoring systems.  This includes the critical task of ensuring the accurate and reliable performance of the linear accelerator treatment machines.  Thus the Medical Physicist is responsible for both the design of a treatment plan and the accurate delivery of the plan.

Radiation safety
A Medical Physicist serves as the Radiation Safety Officer at many cancer centres.  This person and his/her designates are responsible for the safe use of all radioactive devices.  This includes the design of radiation bunkers, acquisition of operating licenses and ensuring compliance with all applicable regulations.

New treatment systems and techniques are developed to improve patient care.  In addition, basic science research is performed to better understand fundamental Biophysics principles.

Medical Physicists participate in the Medical Physics residency program.  They are also active in the training of radiation oncologists, radiologists and radiation therapists.
