Provision Center for Proton Therapy – Medical Dosimetrist I
The Medical Dosimetrist I is responsible for designing a treatment plan and carrying out calculations with mathematical accuracy for the delivery of radiation treatment based on the radiation oncologist’s prescribed course of radiation therapy. This treatment plan takes into consideration tumor pathology, tumor volume and inherent dose-limiting structures surrounding the tumor. The treatment plan and radiation field placement techniques are constructed utilizing sophisticated computer equipment and technology. The medical dosimetrist, along with the radiation oncologist and medical physicist, will work to construct a treatment plan that will meet the prescription written by the oncologist, ensuring that the patient will not lose important healthy organ function and that the radiation delivered will not affect healthy surrounding tissue. These treatment plans not only include the use of radiation, but also, in many cases, involve the use of radioactive elements during interstitial brachytherapy procedures. Once the treatment plan is complete, the medical dosimetrist will work closely with the radiation therapists in the implementation of the prescribed plan.
- Design a treatment plan by means of computer and/or manual computation with optimal beam geometry (dose-volume constraints, dose calculations) to deliver a prescribed radiation dose and spare critical structures in accordance with the radiation oncologist’s prescription.
- Identify and contour normal and dose-limiting structures by utilizing images from one or more data sets (fusion and registration, contouring/segmentation). Assumes proficiency in image registration with various image data sets to include CT, MRI and PET.
- Create and transfer reference images and localization markers for portal verification and treatment delivery to include DRRs, CBCTs and other IGRT methods, as specified (review of final treatment plan).
- Supervise, perform or assist in simulations and tumor localization using specified imaging modalities 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.
- Supervise, perform or assist in the planning and implementation of the production of molds, casts and other immobilization devices.
- 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.
- Perform calculations for the accurate delivery of the prescribed dose, document all pertinent information in the patient record and verify the mathematical accuracy of all calculations by an approved method; monitor accuracy of delivery (ports, dose, etc.).
- Provide assistance and technical support to the medical physicist in radiation safety and protection, qualitative machine calibrations, quality assurance of treatment plans and radiation oncology equipment (equipment, software and systems acceptance testing, maintenance and commissioning).
- Operate and perform quality assurance, under the direction of the medical physicist, on the treatment planning computer(s) (equipment, software and systems acceptance testing, maintenance and commissioning).
- Supervise, perform or assist in the application of specific methods of patient and/or beam dosimetry as directed by the medical physicist; special procedures (SRS, SBRT, HDR, etc.).
- Teach applied aspects of medical dosimetry to students, radiation therapists and residents.
- Bachelors of Science in a physical or biological science or registered radiation therapy technologist.
- Eligible to become certified by the MDCB
- Flexibility to handle multiple tasks and deadlines.
- Proven time management skills.
- Knowledgeable in the areas of anatomy, physiology, clinical oncology, radiobiology, radiation physics, and radiation safety.
- Possess good communication and interpersonal skills to facilitate the exchange of information with patients, family members, and 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.
- Knowledgeable in using RaySearch, XIO, Monoco, Focal, and MOSAIQ
- Has basic to intermediate knowledge of Microsoft Office Suite
