Master of Science in Medical Dosimetry

The Master of Science in Medical Dosimetry (MSMD) at Suffolk University combines coursework and hands-on clinical training that will prepare you for an entry level dosimetry position.

Medical dosimetrists are integral members of the radiation oncology team who create computerized treatment plans and perform dose calculations for patients undergoing radiation therapy. As “architects” of radiation therapy, they design plans to deliver a curative dose to tumors while limiting exposure to nearby healthy organs.

At Suffolk, you will learn from expert board-certified dosimetrists and physicists at top Boston hospitals who provide didactic and clinical instruction. Our competency-based clinical curriculum incorporates the latest planning techniques including 3D, IMRT, VMAT, brachytherapy, and stereotactic. Students also have the unique experience of a 3-week rotation in proton treatment planning. You will be prepared to be a clinically competent professional who can communicate effectively, think critically, and engage in evidence-based practice.

Supervised clinical rotations are completed at our affiliates including

  • Massachusetts General Hospital (MGH)
  • Brigham and Women’s Hospital (BWH)
  • MGH at Newton Wellesley Hospital
  • Dana-Farber/Brigham and Women’s Cancer Center at Milford Regional Medical Center
  • MGH North Shore Cancer Center
  • Beth Israel-Lahey Health
  • Rhode Island Hospital
  • South Shore Hospital

The variety of clinical sites ensures exposure to working in multiple settings including a major academic center as well as a smaller community setting. Every student also gains experience using the two major treatment planning systems which are Eclipse and RayStation.

Upon graduation, you will be eligible to apply to sit for the certification exam offered by the Medical Dosimetrist Certification Board. At this time, there are no licensure requirements for Medical Dosimetrists in any state or the District of Columbia.

The mission of the Medical Dosimetry program is to provide students with a rigorous and comprehensive education in the discipline. Students will receive instruction from a multifaceted faculty and in diverse clinical settings in New England. Our students will use the most advanced technologies to develop exceptional clinical skills and research experiences that will prepare them for entry level positions. Graduates of our program will think critically, communicate effectively, and appreciate the importance of continued education in maintaining their competence.

The MS in Medical Dosimetry program (MSMD) is a full-time program and includes one summer semester of a required academic internship in a clinical setting.

Most students who complete the MSMD program have no prior coursework in radiation therapy or medical dosimetry. Students who do not possess a background in radiation therapy complete the MSMD program in 21 months and begin their first semester in September.

Students possessing a Bachelor of Science in Radiation Therapy may complete the program in 17 months and begin their first semester in January.

Admission Requirements

A background in radiation therapy is not required. Most of our accepted students have undergraduate degrees in physics, biology, chemistry, pre-med, and health sciences. We have also accepted career changers with backgrounds such as marketing and environmental science. All applicants must meet the following minimum requirements:
  • Bachelor’s degree
  • 3.0 cumulative GPA

Completion of the following pre-requisite courses with a grade of C or higher:

  • Calculus I
  • Physics I & II with labs
  • Biology
  • Anatomy & Physiology I & II with labs

Shadow Experience

All applicants must complete a clinical shadow experience before the corresponding application deadline, however it is recommended that applicants complete a shadow in advance as soon as they identify an interest in applying to the program. This will require at least 4 hours of your time and consists of observing a certified Medical Dosimetrist at work to assure your suitability for the career you are pursuing.

Applicants are encouraged to complete the shadow experience at a nearby medical institution of their choice by contacting the Radiation Oncology Department and requesting a Medical Dosimetry shadow.

The following information will need to be provided in the admissions application form so we can request feedback about the shadow:

  • Name of individual(s) with whom you shadowed

If you need assistance scheduling a shadow, the Suffolk Medical Dosimetry Program can also arrange it for you at one of our local hospital affiliates in Boston. Please be advised that as of 3/11/2020, our clinical partners have advised us that we are not able to set up on-site shadow experiences until further notice. If you are interested in Medical Dosimetry, and are unable to secure a shadow at a site near you, we can schedule you for a 2 hour virtual demonstration to meet shadow requirement purposes.

Clinical Information

Clinical rotations begin in the spring semester of the first year of the program. Students are advised that they may be required to participate in a few quality assurance procedures that are typically completed in the evenings.

The clinical schedule is:

  • Year 1
    Spring: Tuesday & Thursday — 8 a.m. - 4:30 p.m.
    Summer: Monday & Friday — 8 a.m. - 4:30 p.m.
    OR Monday - Thursday — 7 a.m. - 5:30 p.m.*
    *This 4-day, 10-hour summer option is not offered at all clinical sites
  • Year 2
    Fall & Spring: Monday, Wednesday, & Friday — 8 a.m. - 4:30 p.m.

Several of our clinical affiliates utilize a hybrid work model where dosimetrists work remotely for a few days each week. Students complete their clinical rotations in person under supervision of dosimetrists who are also on site, but there may be occasions where instruction is provided remotely via videoconferencing. During the full-time summer practicum and at the discretion of the clinical site, students may be able to complete remote clinical education not to exceed 50% of the required clinical hours in any given week.

Students are required to provide their own transportation when assigned to clinical sites that are not easily accessible via public transportation.

This applies to MGH North Shore Cancer Center, Dana-Farber/Brigham and Women’s Cancer Center at Milford Regional Medical Center, and Rhode Island Hospital.

All students are required to comply with various requirements of our clinical affiliates in order to be cleared to start clinical rotations. This includes submitting information required for background checks such as the Criminal Offender Record Information (CORI) and providing proof of required immunizations.

Students are also required to obtain a flu shot and a TB/PPD test at their own expense based on the schedule determined by their clinical site.

A Professional Liability Insurance policy will be provided through Suffolk University that covers students during clinical rotations.

Students enrolling in Fall 2022 and later will be required to obtain CPR certification at their own cost. This will be required prior to the start of clinical rotations and must remain current for the duration of all rotations.

"Walking into the program I was nervous and uncertain. Now I am positive that I will graduate as an accomplished Medical Dosimetrist. My coursework gave me a strong grasp of the fundamentals, which set me up for success in our clinical rotations. It is because of this thorough preparation that I was able to not only observe, but work in tandem with physicians, physicists and dosimetrists to design optimal radiation treatment plans."

Daniel Miller, MSMD ‘21

Suffolk has become my home, and my cohort has become a family. The small cohort size has allowed me to work directly with the program faculty as well as my peers. Our professors create a welcoming environment which encourages us to ask questions and collaborate. Through my experience in the program, my classes, and my clinical rotations at multiple sites, I’ve expanded my network and found a job prior to graduation.
