Why Is Accuracy So Important?

• Consistency and uniformity  Within the department  Prospective data collection 

Analysis of local practice and impact on patients



Within the context of clinical trials  Compliance with trial specifications  Allows for collections of data and comparison of outcomes and toxicity at a larger international scale

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