Role of the Medical Physicist in CyberKnife Treatment

In the process of treatment planning, medical physicists play a key role at CyberKnife Center of Chicago, working closely with other members of the treatment team to support imaging, treatment planning and quality assurance testing of our CyberKnife® technology and its components.

Our physics team is responsible for the development of a customized treatment plan to deliver the radiation dose prescribed by each patient’s treating radiation oncologist. The physicist works with the Radiation Oncologist to determine the angles and intensities of the CyberKnife’s radiation beams that will be delivered during treatment using the technology’s treatment planning system.

This process directs the radiation dose precisely to the three-dimensional shape of the tumor being treated, minimizing radiation exposure to surrounding healthy tissue. When treating areas near critical anatomy or structures, such as the spinal cord, sparing normal tissue is particularly important.
