The aim of this study is to calculate the JO-IMRT dose distributions based on the AAPM TG-119 usingMonte Carlo (MC) simulation and Prowess Panther treatment planning system (TPS) (Panther, ProwessInc., Chico, CA). JO-IMRT dose distributions of AAPM TG-119 were calculated by the TPS and wererecalculated by MC simulation. The DVHs and 3D gamma index using global methods implemented inthe PTW-VeriSoft with 3%/3 mm were used for evaluation. JO-IMRT dose distributions calculated by TPSand MC were matched the TG-119 goals. The gamma index passing rates with 3%/3 mm were 98.7% formulti-target, 96.0% for mock prostate, 95.4% for mock head-and-neck, and 96.6% for C-shape. The dose inthe planning target volumes (PTV) for TPS was larger than that for the MC. The relative dose differencesin D99 between TPS and MC for multi-target are 1.52%, 0.17% and 1.40%, for the center, superior andinferior, respectively. The differences in D95 are 0.16% for C-shape; and 0.06% for mock prostate. Mockhead-and-neck difference is 0.40% in D99. In contrast, the organ curve for TPS tended to be smaller thanMC values. JO-IMRT dose distributions for the AAPM TG-119 calculated by the TPS agreed well with theMC.
