Medical Dosimetrist (Senior/Staff)

Boston Medical Center•Boston, MA

1d•Onsite

About The Position

The Senior Medical Dosimetrist designs comprehensive, highly complex radiation treatment plans for patients undergoing radiation therapy, serving as a critical member of the radiation oncology clinical team. Operating under the general supervision of the Chief of Physics, this role executes clinical duties in strict compliance with established Standard Operating Procedures (SOPs) and Massachusetts Department of Public Health (DPH) regulations. Beyond individual patient assignments, this position exerts a departmental impact by distributing work assignments among the dosimetry team, driving the strategic optimization and restructuring of dosimetry workflows, and delivering daily clinical training and mentorship to lower-level staff, residents, and students.

Requirements

Hold a Bachelor's Degree in addition to certification requirement below. Or equivalent combination of education and experience.
Senior position requires more than 5 years active clinical experience as a medical dosimetrist.
Staff positions could be considered for individuals with more than 1 year of clinical experience or requirement to graduate from JRCERT accredited dosimetry program
(Active) Certified Medical Dosimetrist by MDCB. For staff positions, a board-eligible status by MDCB will also be considered.
Knowledge of radiation biology, dose fractionation, early/late tissue effects, and normal tissue tolerances.
Knowledge of radiation safety standards and the clinical compliance guidelines enforced by the Massachusetts Department of Public Health (DPH).
Knowledge of bony and soft-tissue cross-sectional anatomy sufficient for precise structure identification and plan assessment.
Skill in utilizing advanced computer software platforms to execute rigid/deformable image fusions and generate complex 3D and 4D treatment plans.
Skill in applying algebraic and trigonometric formulations alongside strong three-dimensional spatial visualization capabilities
Ability to operate with absolute accuracy under strict clinical Standard Operating Procedures (SOPs) without unauthorized deviation.
Ability to synthesize complex technical data and communicate plan variables, positioning instructions, and parameters clearly to physicians, physicists, and radiation therapists.

Responsibilities

Designs, generates, and documents complex computerized and manual radiation treatment plans (including 3DCRT, IMRT, VMAT, SRS/SBRT, and Brachytherapy) to deliver prescribed radiation doses to defined tumor volumes while minimizing exposure to normal, dose-limiting critical structures.
Manages the operational distribution of clinical work assignments among dosimetry team members and leads initiatives aimed at evaluating and restructuring internal dosimetry processes and procedures.
Identifies, isolates, and contours normal and critical anatomical structures across multiple modalities—including CT, MRI, PET, and ultrasound—and executes rigid or deformable image fusions to ensure precise target localization.
Conducts daily hands-on clinical training, technical onboarding, and competency assessments for medical dosimetry students, residents, lower-level staff, and visiting physicians on complex planning methodologies.
Performs and verifies the mathematical accuracy of monitor unit and timer setting dose calculations utilizing manual software systems, ensuring complete data integrity within the electronic patient record prior to physicist review.
Coordinates treatment simulations and tumor localization on dedicated imaging equipment, and consults directly with therapists, physicists, and physicians to design optimal patient positioning and custom immobilization devices (e.g., molds, casts, compensation filters).
Executes routine quality assurance checks on patient treatment plans to guarantee approved delivery parameters, and manages the exhaustive documentation, data collection, and submission requirements for patients enrolled in clinical trials and research protocols.
Audits and executes accurate technical documentation required for billing, coding, and regulatory reimbursement compliance relative to the submitted procedure codes.
