Position Summary:

The dosimetrist is responsible for translation of prescribed doses of radiation used in treatment of cancer patients into precise, safe and accurate plans. In collaboration with medical physicists and radiation oncologists, he/she participates in conceiving and optimizing the treatment plan, and is available for consultation with the radiation therapists during execution of the treatments.


  • Assist in simulations and tumor localization using specified imaging devices including, but not limited to CT, MRI, and PET.
  • Supervise, perform, or assist in the planning and implementation of the fabrication of compensation filters, custom shields, wedges, and other beam modifying devices.
  • Perform and assist in the planning and implementation of the production of moulds, casts, and other immobilization devices.
  • Import patient image studies and localization markers for treatment planning as specified by the radiation oncologist.
  • Identify and contour normal and dose-limiting structures by utilizing images from one or more data sets. Assumes proficiency in image registration with various image data sets to include CT, MRI and PET.
  • Actively discusses the design of the treatment plan with the radiation oncologist and medical physicist.
  • Design a treatment plan by means of computer and/or manual computation with optimal beam geometry to deliver a prescribed radiation dose and spare critical structures in accordance with the Radiation Oncologist's prescription.
  • Perform calculations for the accurate delivery of the Radiation Oncologist’s prescribed dose, document all pertinent information in the patient record, and verify the mathematical accuracy of the calculations using a system established by the Medical Physicist.
  • Create and transfer reference images and localization markers for portal verification and treatment delivery to include DRRs, CBCTs and other IGRT methods, as specified.
  • Communicate with the radiation therapist(s) and assume an advisory role in the implementation of the treatment plan including: the correct use of immobilization devices, compensators, wedges, field arrangement, and other treatment or imaging parameters.
  • Operates and performs quality assurance, under the direction of the Medical Physicist, on the treatment planning computer system(s).
  • Perform or assist in the application of specific methods of patient and/or beam dosimetry as directed by the Medical Physicist.
  • Under the direction of a Medical Physicist, assist in brachytherapy procedures by performing treatment planning and dose calculations. May also perform or assist in the receiving, loading, and shipping of radioactive materials.
  • Utilize radiation monitoring devices to measure radioactivity and perform assays.
  • Teach applied aspects of medical dosimetry to students, radiation therapists and residents.
  • Participate in clinical research for the development and implementation of new techniques.
  • Participate in quality improvement processes.
  • Participates in the implementation of new clinical programs in the department as assigned by the Lead Dosimetrist and/or the Clinical Manager of Medical Physics and Dosimetry and/or the Director of Medical Physics.
  • Participates in clinical conferences and teaching as assigned by the Lead Dosimetrist and/or the Clinical Manager of Medical Physics and Dosimetry and/or the Director of Medical Physics.


Bachelor's Degree (preferably in Radiation Therapy Technology or equivalent) or Associates degree in Radiation Therapy Technology in addition to graduation from a Medical Dosimetry JRCERT accredited program of at least 12 months and Board certification as a Medical Dosimetrist preferred (CMD) or eligible to sit for the Medical Dosimetry Certification Board (MDCB) Examination and pass exam within the guidelines as outlined in the MDCB Certification Handbook. Participate in continuing education as required by the MDCB or an equivalent combination of education and/or experience.

  • Knowledgeable in the areas of anatomy, physiology, clinical oncology, radiobiology, radiation physics, and radiation safety.
  • Expertise in the technical aspects of radiation oncology and medical physics to develop optimal treatment plans.
  • Knowledgeable in health care informatics-including the resources, devices and methods to acquire, store and retrieve data. Tools include computers as well as clinical guidelines, current medical terminology, information and communication systems.
  • Possess good communication and interpersonal skills to facilitate the exchange of information with patients, family members, the radiation oncology treatment team as well as outside entities.
  • Has high level critical thinking and problem solving skills.
  • Works independently, but in collaboration with the Radiation Oncologist and Medical Physicist.
  • Has working knowledge of radiation safety principles and practices.
  • Has the ability to interpret criteria and develop treatment plans as defined by relevant treatment protocols.
