Dose volume histogram

A dose volume histogram, or DVH, is a quick way to graphically show how much radiation dose a structure (like the heart) receives as part of radiation treatment. It shows how much dose is received by a percentage of the structure. It can give several important pieces of information, such as the maximum dose, minimum dose, or how much dose is received by 50% of the structure. However, it is important to know that a DVH does not give information about the location of dose, such as where the maximum dose is located in a structure.
