cancer patients. This role supports all clinical, technical, and
quality assurance activities related to radiation-producing
equipment, treatment planning, and radiation safety. The physicist
collaborates closely with radiation oncologists, dosimetrists,
therapists, and engineers to maintain the highest standards of
patient care and safety. Key Responsibilities Ensure accurate and
safe delivery of prescribed photon and proton therapy treatments in
accordance with physician intent and departmental standards.
Provide clinical physics support for simulation, setup, and
treatment delivery, verifying immobilization, imaging, and patient
positioning for complex modalities (IMRT, VMAT, SRS, SBRT,
brachytherapy, and proton therapy). Collaborate with dosimetrists
and physicians to develop, optimize, and review treatment plans,
including pencil beam scanning, adaptive therapy, and advanced
photon techniques. Perform independent dose calculations, monitor
unit verifications, and chart checks to maintain treatment accuracy
and quality compliance. Participate in adaptive workflows,
including deformable registration, dose reconstruction, and plan
adaptation. Conduct acceptance testing, commissioning, calibration,
and routine QA of Linac, proton systems, CT simulators, and
associated imaging/dosimetry equipment per AAPM/IAEA standards.
Maintain comprehensive QA programs and documentation to ensure
consistent performance and regulatory compliance (ACR, NRC, FDA,
The Joint Commission). Troubleshoot and resolve equipment or
software issues in collaboration with vendors and service
engineers. Support brachytherapy operations, including source
