Radiation Oncology Dosimetrist, Hybrid

Job Description
General Summary 
Under general supervision, provides comprehensive treatment planning by calculating computerized isodose plans for radiation oncology patients. 
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. 
Computes dose distributions and generates isodose curves for external beam radiation therapy and brachytherapy in accordance with departmental procedures and generally accepted dosimetry practices. 
Consults with Radiation Oncologists, Physicists and Senior Dosimetrists to generate optimal treatment plans for external beam radiation therapy and brachytherapy using different treatment planning computers.  Incorporates anatomical information from computer tomography, magnetic resonance imaging, radiographs, ultrasound, etc. to minimize dose to normal structures and maximize dose to treatment targets identified by physicians. 
Calculates 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. 
Performs 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 physicist and physician on dose errors and changes in treatment parameters. 
Assists in complex simulation and fabrication of custom treatment devices.
