The Medical Dosimetrist determines how much radiation is delivered to a tumor site. Under the supervision of a medical physicist, the Medical Dosimetrist calculates and generates radiation dose
Distributions in accordance with the treatment plan developed by the radiation oncologist; and uses
Knowledge of physics, anatomy and radiobiology to design optimal treatments that apply an effective dose to the targeted area while sparing normal tissue that surrounds the treatment site.
NATURE AND SCOPE:
Interacts with staff, physicians, patients and their families, other healthcare providers, Hospital and University officials, and the public.
Designs a treatment plan by means of computer and/or manual computation that will deliver a prescribed radiation dose and field placement technique in accordance with the Radiation Oncologist’s prescription to a defined tumor volume.
Consider dose-limiting structures in the design of treatment plans and documents dose in accordance with the Radiation Oncologist’s prescription.
Coordinates treatment simulations and tumor localization on dedicated devices, including CT, MRI, and
PET when indicated, for radiation oncology treatment planning.
Performs, or assists in the planning of the fabrication of compensation filters, custom shields, wedges, and other beam modifying devices.
Performs, or assists in the planning of the production of moulds, casts, and other immobilization devices.
Oversees therapists staff in the implementation of the treatment plan including the correct use of immobilization devices, compensators, wedges, field arrangement, and other treatment variables.
Performs calculations for the accurate delivery of the Radiation Oncologist’s prescribed dose, documents all pertinent information in the patient record, and verifies the mathematical accuracy of all calculations using a system established by the Medical Physicist.
Provides physics and technical support to the Medical Physicist, in radiation protection, qualitative machine calibrations, and quality assurance of the radiation oncology equipment.
Oversees, performs, or assists in the application of specific methods of dosimetry including ion chamber, Thermoluminescent (TLD), or film measurement as directed by the Medical Physicist.
