(c) Gamma histogram generated for the same plan using a different 3D dosimeter (Delta4) showing the 94.7% passing rate and (d) absolute dose profiles in the Delta4 illustrating meas < calc over the entire high dose region. (e) TPS dose distribution and (F) 3D MGDR reconstructed dose vs TPS dose for a sagittal plane through the high dose region, showing the clear bias of meas < calc as the shaded region.

Figure Lengend Snippet: Dose verification of the AP field for the prostate case. The left panel shows the dose distribution (isodose lines) calculated by the KonRad TPS together with the ones measured with the MapCheck device. The right panel shows the vertical profile of the dose distribution. The measured dose points are shown as yellow circles, the calculated dose profile as a solid line. For this field 202 out of 205 points passed the 3%/3mm acceptance criteria.

Article Snippet: The verification plans were generated and the beams from each plan were delivered individually on the MapCheck device using a Siemens Primus linear accelerator.
