Therapy Medical Physicist (Adaptive Radiation Therapy)

Mary Bird Perkins Cancer Center•Baton Rouge, LA

5d•Onsite

About The Position

Mary Bird Perkins Cancer Center is seeking a Therapy Medical Physicist to join its Baton Rouge team as it launches CBCT-guided online adaptive radiation therapy across its C-arm linac fleet. This is a full-scope clinical therapy physics role in a busy, multi-site cancer program, working with a team of approximately fifteen physicists and residents and a modern Elekta fleet. The physicist will share responsibility for treatment planning quality, machine and patient-specific quality assurance, SRS and SBRT, motion-managed treatments, regulatory and accreditation compliance, and acceptance and commissioning of new technology across the network. The role will help build the C-arm adaptive radiotherapy program, including commissioning the Elekta ONE Online adaptive platform, validating auto-segmentation and synthetic-CT dose accuracy, developing policies and procedures, and working as an adaptor at the console. The physicist will also support adaptive workflows on the Elekta Unity MR-linac. The balance between adaptive work and broader clinical service will be shaped around the physicist’s interests and program needs. Additional opportunities include leading research, mentoring residents in the CAMPEP-accredited Medical Physics Residency Program, contributing to graduate education in partnership with LSU, and participating in the in-house Physics DevOps software development program. The role is open to experienced adaptive physicists and strong recent graduates of CAMPEP-accredited residencies, with scope to support an early-career physicist.

Requirements

M.S. or Ph.D. in Medical Physics from a CAMPEP-accredited program, or a Ph.D. in Physics with equivalent medical physics training.
Completion of a CAMPEP-accredited residency in Therapeutic Medical Physics.
ABR certification in Therapeutic Medical Physics, or board-eligible with a clear path to certification.
Eligibility for licensure as a Medical Physicist in the State of Louisiana.
Sound, timely clinical judgment under real-time conditions.
Exceptional analytical, communication, and problem-solving skills.
Ability to work effectively both independently and collaboratively with therapists, dosimetrists, and physicians.
Passion for continuous learning and clinical excellence.

Nice To Haves

Online adaptive experience, particularly with Elekta ONE/Unity, Varian Ethos, or equivalent; experience as an adaptor at the console is of particular interest.
Proficiency with Monaco or comparable treatment planning systems.
SRS/SBRT experience.
Experience with multi-site clinical operations and regulatory compliance.
Scripting or software development experience, particularly in Python.

Responsibilities

Serve as physicist-adaptor in online adaptive workflows on C-arm linacs and the Unity MR-linac, reviewing and editing auto-generated contours, overseeing on-table re-optimization, evaluating and selecting plans, independently verifying dose, and clearing verification imaging before beam-on.
Lead acceptance testing, commissioning, and clinical release of adaptive planning and delivery systems, including validation of deformable registration, site-specific auto-segmentation models, and CBCT/synthetic-CT dose calculation accuracy.
Develop and maintain adaptive-specific quality assurance, including end-to-end testing, periodic QA of the adaptive chain, and independent monitor unit verification methodology for adapted plans consistent with AAPM TG-219.
Perform and oversee routine and non-routine linac QA, patient-specific QA, and annual regulatory testing across the treatment fleet.
Provide physics support for SRS, SBRT, and hypofractionated treatments, including motion management and DIBH workflows.
Oversee treatment planning quality in Monaco, including plan review, complexity surveillance, and secondary dose calculation.
Conduct risk analysis and process mapping for new workflows using FMEA methodology per AAPM TG-100.
Ensure compliance with applicable regulatory and accreditation standards, including Louisiana state regulations, ACR/ASTRO APEx, TJC, and NRC requirements, and support institutional accountability for technical and regulatory performance.
Contribute to technology evaluation, selection, and installation as the department continues its capital investment cycle.
Train and mentor therapists, dosimetrists, and physician colleagues on adaptive workflows and new technology.
Participate in the departmental after-hours and weekend physics call rotation.
Pursue research in adaptive radiotherapy, dose accumulation, plan complexity, and treatment automation.
Mentor medical physics residents in the CAMPEP-accredited consortium program and guide research projects toward publication-ready standards.
Contribute to graduate education through teaching, curriculum development, or course direction in partnership with LSU.
Contribute to Physics DevOps, the in-house software development program producing clinical and administrative tools.
Engage with the medical physics community through AAPM, ASTRO, professional society service, and conference participation.
Pursue continuous professional development to maintain certification and licensure.
