Brachytherapy treatment planning commissioning: effect of the election of proper bibliography and finite size of TG-43 input data on standard treatments.

ABSTRACT: The aim of this work is to evaluate the performance of a commercial brachytherapy treatment planning system (TPS) with TG-43 Vendors Input Data (VID), analyze possible discrepancies with respect to a proper reference source and its implications for standard treatments, and judge the effectiveness of certain widespread recommended quality controls to find potential errors related with the interpolations of TG-43 VID tables. The TPS evaluated was a BrachyVision 8.6 loaded with TG-43 VID for a VariSource high-dose-rate 192Ir source (Vs2000). The reference data chosen were the TG-43 data published in the literature. In the first step, we compared TG-43 VID with respect to the chosen reference data. Next, we used percent dose-rate differences in a point array matrix to compare the outcomes of t
