  • Review the protocol patient's treatment charts, extract pertinent data, enter data into the computerized patient database and compare the results of the patient's treatment with the protocol requirements. Write a description of any deviation to be included in the evaluation summary.
  • Calculate the radiation doses in points specified by the protocols and review the results for compliance.
  • Consult with physicists and dosimetrists at participating hospitals concerning these dose calculations in order to resolve discrepancies.  This analysis may concern the numerical calculations, quality assurance procedures, treatment planning methods, radiation beam parameters, etc.
  • Extract data and compiles reports from the QARC database and/or from patients' treatments records to answer research questions or to assist in the development of optimal treatments for new protocols.

  • May review new protocols in development and contribute to improvement in the writing of the dosimetry of these protocols and new model protocols.
  • Perform other duties as required.





  • Bachelor's degree in physics or mathematics, graduation from a dosimetry program, or completion of a Radiation Therapist program (RTT) with some experience in dosimetry.
  • 1-2 years of experience in radiotherapy treatment planning, some of which may be replaced by work experience as a radiation therapist.
  • Basic knowledge of radiation treatment planning.
