Accuracy and limitations
•
Factors affecting DVH accuracy:
– Accuracy to which VOI is delineated (Main contribution)
– Dose bin size
– Distance Map voxel size
– Sampling method and sampling resolution
– Shape of VOI
– Dose Calculation Algorithm (difference in modelling
heterogenities, penumbra…)
– Dose voxel size
