Adaptability in a fast-paced clinical environment

Responsibilities

Treatment Planning & Dosimetry: Develop and calculate complex radiation treatment plans using 3D, IMRT, VMAT, SBRT, SRS, brachytherapy, or other advanced planning modalities.
Utilize treatment planning systems (TPS) to simulate and optimize dose distribution while protecting surrounding critical structures.
Perform dose calculations and verify accuracy using established physics and clinical protocols.
Prepare devices such as blocks, compensators, immobilization tools, or custom bolus materials as needed.
Collaboration & Clinical Support: Work closely with Radiation Oncologists to interpret prescriptions and translate them into clinically sound treatment plans.
Partner with Medical Physicists on quality assurance (QA), equipment calibration, and plan validation.
Provide technical guidance to Radiation Therapists during treatment setup and delivery.
Quality Assurance & Compliance: Participate in chart checks, plan reviews, and departmental QA processes.
Ensure all treatment plans meet national guidelines, safety protocols, and accreditation standards.
Maintain accurate documentation in the oncology EMR and treatment planning systems.
Technology & Systems Management: Operate and maintain familiarity with imaging systems (CT simulation, MRI fusion, PET/CT) used for treatment planning.
Assist with system updates, testing, and troubleshooting of planning software and radiation delivery platforms.
Patient Care & Safety: Support simulation workflows by assisting with imaging acquisition and patient positioning as needed.
Ensure patient safety by applying ALARA principles and adhering to regulatory requirements.
