Table 1 Systematic differences between the dose distributions estimated with PENELOPE and pDPM for the photon test cases included in this work

From: DPM as a radiation transport engine for PRIMO

Test case α [%] Δ[%] α[%] Δ[%]
Described in section Photon transport in a multi-layer phantom     
(all voxels) 14.2 -5.0 17.0 0.2
(in the air layer) 97.0 -5.3 0 0
(excluding the air layer) 32.1 -0.2 20.4 0.2
Described in “Photon transport in a MLC” section 26.0 -0.4 13.3 0.3
Head&Neck 32.4 -0.8 17.8 0.7
Lung 36.6 -0.8 11.7 0.5
Brain 30.5 -0.6 7.0 0.7
Prostate 28.1 -0.4 18.2 0.4
  1. They are expressed as the percentage of voxels α with a systematic deviation Δ given in percentage of the maximum dose
