Are gamma passing rate and dose–volume histogram QA metrics correlated?
Purpose The quality of a measured distribution of dose delivered against its corresponding
radiotherapy plan is routinely assessed by gamma index (GI) and dose–volume histogram …

Statistical approach to the selection of the tolerances for distance to agreement improves the quality control of the dose delivery in radiotherapy
In the study, a local approach to setting reference tolerance values for the distance-to-
agreement (DTA) component of the gamma index is proposed. The reference tolerance …
