Abstract

The invention provides a method and system for adapting a radiation therapy treatment plan based on a biological model. The method includes the acts of preparing a treatment plan for a patient, acquiring images of the patient, performing deformable registration of the images, acquiring data relating to a radiation dose delivered to the patient, applying a biological model relating the radiation dose delivered and a patient effect, and adapting the radiation therapy treatment plan based on the deformable registration and the biological model.

Description

technical field [0001] This application claims priority to U.S. Provisional Patent Application No. 60 / 701,580, entitled "SYSTEM ANDMETHOD FOR FEEDBACK GUIDED QUALITY ASSURANCE ANDADAPTATIONS TO RADIATION THERAPY TREATMENT," filed July 22, 2005, the entire contents of which are incorporated by reference in this. Background technique [0002] Over the past few decades, improvements in computer and networking technology, radiation therapy treatment planning software, and medical imaging equipment (CT, MRI, US, and PET) have been incorporated into radiation therapy practice. These improvements have spurred the development of image-guided radiation therapy ("IGRT"). IGRT is radiation therapy that uses cross-sectional images of a patient's internal anatomy to better target radiation doses to tumors while reducing radiation exposure to healthy organs. Controlling the radiation dose delivered to a tumor with intensity modulated radiation therapy (IMRT) involves changing the size, ...
