  1. General Summary

Under direct supervision, the student worker participating in the UMMC Dosimetrist Training program learns to perform treatment planning by calculating computerized isodose plans for radiation oncology patients.  Upon completion of the training, students will be technically competent and knowledgeable about the concepts related to medical dosimetry and able to actively participate in the development of various treatment plans as an entry level medical dosimetrist.   This position is a full time position employed in Radiation Oncology for an eighteen month (August through July) period.

Principal Responsibilities and Tasks

The following statements are intended to describe the general nature and level of work being performed by people assigned to this classification.  They are not to be construed as an exhaustive list of all job duties performed by personnel so classified.


  1. Learn to compute dose distributions and generate isodose curves for external beam radiation therapy and brachytherapy in accordance with departmental procedures and generally accepted dosimetry practices.
    1. Consults with Radiation Oncologists, Physicists and Senior/Staff Dosimetrists to generate optimal treatment plans for external beam radiation therapy and brachytherapy using different treatment planning computers
    2. Learn to calculate treatment machine settings including field arrangements and shapes (dose to be delivered from machine to patient); documents calculations and records treatment data in therapy chart.
    3. Learn to perform verification checks and applies quality assurance procedures to ensure accuracy of dose calculations.  Evaluates patient charts to ensure that the treatment plan reflects the prescriptions, the documentation is complete and the dose calculations are accurate.  Reports to dosimetrists, physicists and physicians on dose errors and changes in treatment parameters.
