A general-purpose Monte Carlo particle transport code based on inverse transform sampling for radiotherapy dose calculation

摘要

Depth dose curves (top row) and lateral profiles at different depths (bottom row) of the 15 MeV photon (left column) and electron (right column) 10 × 10 cm parallel beams in a 30×30×30 cm water phantom. PTM results are shown in red lines while EGSnrc results are shown in blue lines. Absolute differences of depth doses are shown in yellow lines (top row) with y-axis on the right. The same color-style applies for all the other figures. The standard deviations of MC simulations (<0.2%) are too small to be visible, hence not shown in this and all the other figures.
