METHOD OF ACCOUNTING FOR TUMOR MOTION IN RADIOTHERAPY TREATMENT

摘要

A method and apparatus accounting for tumor motion during radiation therapy is provided. The method allows for radiation therapy treatments based on updated radiation therapy plans. For each fractionate radiation treatment that results in an updated radiation treatment, radiation treatment images are acquired, automatically segmented, and then subject to deformable registration to develop updated contours and an updated radiation therapy plan. The apparatus (1) includes a processing unit (3) that is connected to an imaging apparatus (5) that takes an image (6) of object (9) and a radiation apparatus (7) that radiates object (9) .
