Degree Offered

Master of Science in medical dosimetry

A medical dosimetrist is a key member of the radiation oncology team who works closely with physicians, physicists, and other members of the radiation oncology team to implement each treatment plan. The medical dosimetrist uses computer software to design and accurately calculate a radiation treatment plan based on the radiation oncologist's prescription, being cognizant of normal tissues and critical structures in the treatment vicinity. The medical dosimetrist maintains a delicate balance between delivering the prescription the physician has written, while ensuring the patient will not lose important healthy organ function. The medical dosimetrist also provides assistance and support to solve diverse physical and technical problems that arise in the clinical environment. Through knowledge of radiation oncology treatment machines and application of principles of physics, anatomy and radiobiology, the dosimetrist generates radiation therapy treatment plans.

Application Procedures

Admission to the medical dosimetry program is competitive and requires completion of a bachelor's degree prior to admission. Application can be made through the GVSU graduate admission website at Initial review of applications for fall begins February 1. The program continues to accept applications that meet the admissions requirements until the start of the program in August.

Interpersonal skills, communication skills, responsibility, and professionalism, among others, are identified as being crucial for success in the profession. Advancement in skill and behavior applicable to such abilities is expected during the professional curriculum. Clinical evaluation includes measurement of affective skills which must continually be met through the clinical advising program for students to continue in clinical education courses. Failure to achieve adequate progress in the clinical advising program will result in a failing grade being issued for that course. All students in the program are expected to comply with the ethical principles that embody the practice of medicine and the medical dosimetry profession. Community service is also expected as are professional scholarship achievements while enrolled in the program.

A criminal background check and a drug screening is required prior to admission into the program.
