Job Description

We are looking for a full-time, board-certified Medical Dosimetrist to become a part of our team at the Cancer Center associated with our organization. The selected candidate will collaborate with a local group consisting of two physicists, another dosimetrist, and two radiation oncologists, providing care to patients using Varian TrueBeam and IX linear accelerators, all supported by an integrated ARIA/Eclipse system. Treatment modalities at our facility include 3DCRT, IMRT, VMAT, SBRT, respiratory gating, and deep inspiration breath hold techniques. This role is backed by a larger network of over 30 dosimetrists across our organization, offering a competitive salary and comprehensive benefits. Our location is in a picturesque suburb south of Pittsburgh, with convenient access to parks, dining, shopping, and some of the finest school districts in Pennsylvania.


Job Overview:

The medical dosimetrist will be tasked with creating clinically effective treatment plans for patients undergoing radiation therapy, working closely with radiation oncologists, radiation therapy technologists, and medical physicists. Responsibilities include engaging in CT simulations, planning radiation treatments, ensuring quality management for radiation oncology patients, and maintaining communication with the clinical team throughout the treatment planning and implementation phases.


Key Responsibilities:

  • Support the radiation therapy technologist (RTT) during the treatment simulation process, including the use of necessary ancillary treatment devices, patient immobilization methods, and positioning techniques for both simulation and treatment. Assist in the creation of these ancillary devices.
  • Accurately contour and delineate normal critical structures and expanded planning structures using various imaging modalities.
  • Conduct rigid and deformable image registration for multi-modality image sets.
  • Utilize principles of radiation physics in treatment planning, including but not limited to: 2D treatment planning, 3D conformal treatment planning, intensity-modulated radiation therapy (IMRT), 4D treatment planning, volumetric modulated arc therapy (VMAT), stereotactic radiosurgery (SRS), stereotactic body radiation therapy (SBRT), and brachytherapy planning.
  • Apply knowledge of radiobiology regarding dose tolerances, time dose fractionation calculations, hypofractionation, BED, and EQD2 calculations, among other applications in the radiation therapy process.
  • Perform accurate radiation dose calculations, both manually and via computer, considering the effects of beam modifying devices, irregular fields, gaps for adjacent fields, and off-axis calculations.
  • Engage in special treatment procedures, including but not limited to total body irradiation (TBI), total skin electron irradiation (TSEI), and intra-operative radiation therapy (IORT).
  • Assist with quality assurance tasks as directed by a qualified medical physicist.
  • Conduct or assist with patient-specific radiation measurements using devices such as diodes, optically stimulated luminescent dosimeters (OSLD), ion chambers, thermo-luminescent dosimeters (TLD), or film measurements as instructed by the medical physicist.
  • Support high dose rate (HDR) and low dose rate (LDR) brachytherapy procedures, including patient setup, simulation, and treatment planning.
  • Participate in quality management in line with departmental policies, national guidelines, and accreditation standards.
  • Perform routine chart checks according to departmental protocols.
  • Engage in charge capture and documentation for billing in accordance with departmental policies.
  • Contribute to clinical research aimed at developing and implementing new techniques in radiation therapy.
  • Participate in educational initiatives by providing training and instruction to new staff members, physician residents, physicist residents, RTT trainees, and medical dosimetrist trainees.
  • Foster a supportive and caring environment for patients, visitors, medical staff, and colleagues.
  • Carry out miscellaneous job-related tasks as assigned by supervising medical physicists.
  • Uphold high ethical standards in interactions with patients, students, trainees, and colleagues.
  • Assist in acquiring patient data through computer-generated datasets from medical imaging devices such as CT, PET, MR, or through manual methods like physical measurements and wire contours, integrating this data into treatment plans and calculations.
  • Ensure accurate transfer of patient and treatment plan information to clinical systems, including record and verify systems, imaging guidance systems, surface guidance systems, treatment delivery systems, and electronic medical records.
  • Maintain a strong commitment to accuracy, attention to detail, and safety, employing critical thinking skills in radiation treatment planning, plan evaluation, and resolving equipment issues and treatment discrepancies.
  • Create clinically optimal treatment plans using knowledge of anatomy and physiology, radiation biology and oncology, radiation safety and protection, mathematics, radiation therapy techniques, physics, and technology. Communicate effectively with the radiation oncologist during the planning process and collaborate with the medical physicist and radiation therapy technologists for plan execution.

Qualifications:

  • A bachelor’s degree is preferred.
  • Completion of a Medical Dosimetry educational program accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT).
  • Certification from the Medical Dosimetrist Certification Board (MDCB) is required.
  • Board-eligible candidates must achieve board certification within two attempts during the first two consecutive years of employment.

Licensure, Certifications, and Clearances:

Certification as a Medical Dosimetrist (CMD) or board eligibility is required. Candidates must maintain sufficient continuing education credits to uphold certification. CPR certification is mandatory based on AHA standards, including both a theoretical and practical skills demonstration within 30 days of hire. Candidates should have a solid overall performance rating in annual reviews and demonstrate proficiency in radiation treatment planning for both simple and complex cases.

  • Basic Life Support (BLS) or Cardiopulmonary Resuscitation (CPR)
  • Certified Dosimetrist

Our organization is an Equal Opportunity Employer/Disability/Veteran.
