Why Is Accuracy So Important?

• OAR delineation has significant impact on dose calculation and plan quality in dosimetry

• IMRT and VMAT are inverse planning techniques and as such are driven by volumes  Target and OAR relationship

• Accurate imaging ensures: 

Decrease in interobserver variability

DVH calculation

 

Greater confidence in predicting toxicity

 “reduction in inter- and intra-observer variability and therefore unambiguous reporting of possible dose-volume effect relationships” (van der Water, 2009)
