1. A method of defining a new region of interest for an existing region of interest using a dose volume histogram, the method comprising using a computer to carry out the steps of:
- generating a dose volume histogram of radiation dose for a pre-existing region of interest;
selecting a subset of the dose volume histogram; and
defining a new region of interest that corresponds to the selected subset of the dose volume histogram.

Abstract
A system and method of defining a new region of interest for an existing region of interest using a dose volume histogram. The method includes the acts of generating a dose volume histogram of radiation dose for a pre-existing region of interest, selecting a subset of the dose volume histogram, and defining a new region of interest that corresponds to the selected subset of the dose volume histogram.
