System and method for shape based retrieval of prior patients for automation and quality control of radiation therapy treatment plans

Abstract

A system and method for determining at least one new treatment plan for at least one new patient, comprising: providing at least one representation of the at least one new patient's at least one organ at risk relative to at least one target; searching for at least one prior treatment plan for at least one prior patient with at least one similar representation; and reviewing the at least one prior treatment plan for the at least one prior patient in order to determine whether the at least one new treatment plan can be improved based on information in the at least one prior treatment plan.

1 . A method for determining at least one similar treatment plan, comprising:
 providing, utilizing at least one overlap volume histogram (OVH) module on at least one computer, at least one representation of at least one new patient's at least one organ at risk relative to at least one target;   determining, utilizing at least one matching module on the at least one computer, at least one prior treatment plan for at least one prior patient with at least one similar representation.
