Figure 2From: Monte Carlo vs. Pencil Beam based optimization of stereotactic lung IMRTVerification of dose engines - γ -plots. γ-plots of the dose distributions measured with film and calculated with MC and fsPB for all tumour sizes for 6 MV (upper set) and 15 MV (lower set). The acceptance criteria for the γ comparisons was set to 3%/3 mm. The tumour outlines are marked by black circles.Back to article page
