TELETHERAPY AND GAMMA STEREOTACTIC COMPUTER SYSTEMS

A licensee must perform acceptance testing on the treatment planning system of teletherapy and gamma stereotactic computer systems according to published protocols accepted by nationally recognized bodies. At a minimum, the acceptance testing must include, as applicable, verification of: A. the source-specific input parameters required by the dose calculation algorithm; B. the accuracy of dose, dwell time, and treatment time calculations at representative points; C. the accuracy of isodose plots and graphic displays; D. the accuracy of the software used to determine sealed source positions from radiographic images; and E. the accuracy of electronic transfer of the treatment delivery parameters to the treatment delivery unit from the treatment planning system.
