Fig. 3From: Monitoring of mechanical errors and their dosimetric impact throughout the course of non-coplanar continuous volumetric-modulated arc therapyAccumulated DVHs for the skull base tumor patient with the largest dosimetric error (patient 1) are shown. The solid, dashed and dotted lines are the DVHs for the planned, accumulated and largest error dose distributions, respectively. Abbreviation: DVHs = dose volume histograms; CTV = clinical target volumeBack to article page
