DVH Metric Value

**Semantic type:** Conceptual Entity

**Definition:** The value of the dose-volume histogram (DVH) metric. This includes the Time Repair Weighting Factor value used. For example, if the dose was 50.2 EQD2Gy, but the institution reported using a Time Repair Weighting Factor equal to 0.5 because the dose was delivered 2 years previously, then the value reported would be 25.1 . As a result, both component and cumulative values reflect the Time Repair Weighting Factor values used, and the value reported reflects the dose the clinician believes reflects the current biological damage.
