NAC459.5936. Electronic brachytherapy devices: Acceptance test; comparison of position indicators; evaluation and approval of parameters for treatment.

     1. Where applicable, an authorized medical physicist for electronic brachytherapy shall perform an acceptance test on the treatment planning system of computer systems used for therapy, using a published protocol which is accepted by a nationally recognized body. The acceptance test must verify, as applicable:

     (a) The input parameters for a source which are 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 source positions from images; and

     (e) If the treatment planning system is different from the treatment delivery system, the accuracy of electronic transfer of the treatment delivery parameters to the treatment delivery unit from the treatment planning system.

     2. The position indicators in an applicator must be compared to the actual position of the source or planned dwell positions as appropriate at the time of commissioning.

     3. Before each regimen for patient treatment, the parameters for the treatment must be evaluated and approved by the authorized user and the authorized medical physicist for electronic brachytherapy for accuracy through means which are independent of those that were used for the determination of the parameters.
