1. A method for generating an adaptive radiation therapy plan, implemented on a machine having one or more processors and one or more storage devices, the method comprising:
obtaining a first image related to one or more target objects generated by a first scan;
obtaining a first radiation therapy plan for treating the one or more target objects, the first radiation therapy plan being associated with the first image;
obtaining a second image related to the one or more target objects generated by a second scan, the second scan being performed later than the first scan; and
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 being the first radiation therapy plan or a second radiation therapy plan associated with the second image, wherein determining the target radiation therapy plan includes at least one of the following processes:
a process for performing an operation for determining one or more regions of interest (ROIs) in the second image and an operation for determining an accumulated dose in the second image in parallel;
a process for performing an operation for estimating a first dose distribution in the second image based on the first radiation therapy plan in parallel with the operation for determining the one or more ROIs in the second image;
a process for performing an operation for automatically determining one or more second ROIs in the second image in parallel with at least one of an operation for receiving a first instruction for modifying or accepting one or more first ROIs that are automatically determined in the second image and an operation for processing the one or more first ROIs based on the first instruction;
a process for performing an operation for determining whether to generate the second radiation therapy plan or continue using the first radiation therapy plan to treat the one or more target objects in parallel with an operation for generating the second radiation therapy plan; or
a process for performing an operation for generating the second radiation therapy plan in parallel with at least one of an operation for receiving an instruction for modifying or accepting one or more eighth automatically determined ROIs and an operation for processing the one or more eighth automatically determined ROIs based on the instruction for modifying or accepting the one or more eighth automatically determined ROIs.
