Who outlines the plan to administer the desired dosage to the treatment area?

• A. Nurse
• B. Radiation Oncologist
• C. Radiation Therapist
• D. Medical Physicist and Dosimetrist

Answer: (D)

The plan for delivering the prescribed dose to the treatment area is created and refined by the Medical Physicist and Dosimetrist. They translate the physician’s prescription and the patient’s imaging into a detailed dose distribution, selecting beam arrangements, energies, collimation, wedges, and any modulation to shape the dose so the target area receives the intended amount while minimizing exposure to surrounding healthy tissue. The dosimetrist builds the actual plan based on imaging and treatment goals, and the medical physicist verifies the calculations, performs quality checks, and ensures the plan can be delivered safely on the treatment machine. The radiation oncologist provides the prescription and defines target volumes, while the radiation therapist delivers the treatment according to the plan.
