SYSTEMS AND METHODS FOR GENERATING ADAPTIVE RADIATION THERAPY PLAN

A method may include obtaining a first image related to one or more target objects generated by a first scan. The method may also include obtaining a first radiation therapy plan for treating the one or more target objects. The method may also include obtaining a second image related to the one or more target objects generated by a second scan. The second scan may be performed later than the first scan. The method may also include determining, based on the first radiation therapy plan, the first image, and the second image, a target radiation therapy plan to treat the one or more target objects. The target radiation therapy plan may be the first radiation therapy plan or a second radiation therapy plan associated with the second image, wherein at least a portion of the determining the target radiation therapy plan may be performed in parallel.
