Table 2 Agreement between the 2D dose distributions as measured with film and calculated with MC and fsPB for the 3%/3 mm and 2%/2 mm γ acceptance criteria; the acceptance (in %) is listed for the whole region (all), the tumour region (tumour) and the region outside the tumour (lung) and for all tumour sizes.
From: Monte Carlo vs. Pencil Beam based optimization of stereotactic lung IMRT
