Use a variety of machines to test and monitor heart patients.
Measures and calculates radiation dose and develops optimum arrangement of radiation fields and exposures to treat patient: Studies prescription, x rays showing area to be treated, and requirements for dose calculation. Selects beam energy, optimum multiple beam arrangement, beam modifying devices, and other factors, using computer, manuals, and guides. Develops several possible treatment arrangements that meet physician’s criteria and submits arrangements for selection by physician. Measures and calculates prescribed radiation dose based upon field sizes, depth of tumor, treatment unit, beam modifying devices, and other information, using manuals, guides, and computer. Calculates and records daily prescribed radiation dose. Explains treatment plan to RADIATION-THERAPY TECHNOLOGISTS 078.361-034. May operate x-ray equipment to obtain diagnostic x ray of patient in treatment position. May simulate treatment procedure to assist in planning treatment.
