Core Responsibilities

Primary Functions

Accurately interpret and execute the radiation treatment plan as prescribed and documented by the radiation oncology team, ensuring all parameters are precisely followed.
Operate highly complex linear accelerators and related equipment to deliver concentrated doses of radiation to a patient's tumor, minimizing exposure to healthy tissue.
Perform daily, monthly, and annual quality assurance (QA) procedures on treatment machines and imaging devices to ensure they are functioning within strict safety and performance tolerance levels.
Position patients with exceptional accuracy for each treatment session using advanced imaging systems (e.g., CBCT, kV/MV imaging) and custom immobilization devices.
Maintain meticulous and legally compliant electronic medical records for each patient, documenting treatment doses, machine settings, imaging verification, and any observed patient reactions.
Educate patients and their families on the radiation therapy process, what to expect during treatment, and potential side effects, offering clear explanations and emotional support.
Monitor the patient's physical and psychological well-being before, during, and after treatment, reporting any changes, side effects, or concerns to the nursing staff and radiation oncologist immediately.
Practice and enforce all radiation safety protocols (ALARA - As Low As Reasonably Achievable) to protect the patient, yourself, and the public from unnecessary radiation exposure.
Create and utilize custom immobilization devices, such as thermoplastic masks or vacuum-lock bags, to ensure patient stability and treatment reproducibility.
Perform complex treatment delivery techniques including Intensity-Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT), Stereotactic Radiosurgery (SRS), and Stereotactic Body Radiation Therapy (SBRT).
Collaborate effectively and professionally within a multidisciplinary team, including radiation oncologists, medical physicists, dosimetrists, and oncology nurses, to ensure coordinated patient care.
Perform status checks on patients undergoing therapy, assessing for treatment-related reactions and providing appropriate recommendations for care as per departmental protocol.
Manage the daily treatment schedule to optimize patient flow and machine time, accommodating emergent cases and patient needs while maintaining an efficient workflow.
Demonstrate a high level of critical thinking and problem-solving skills to troubleshoot equipment issues or resolve patient setup discrepancies in real-time.
Participate in patient chart rounds and departmental meetings, providing valuable input on patient progress, treatment delivery, and quality improvement initiatives.

Secondary Functions

Assist in the clinical instruction and mentorship of radiation therapy students, providing guidance on technical skills, patient care, and professional conduct.
Contribute to the development and implementation of new departmental policies, procedures, and quality improvement projects aimed at enhancing patient safety and care.
Maintain a clean, organized, and well-stocked treatment environment, including ordering and managing inventory for clinical supplies.
Participate in continuing education and professional development activities to stay current with new technologies, treatment techniques, and best practices in radiation oncology.
Assist medical physicists with data collection for commissioning new equipment or implementing new treatment modalities.
