1. A method for Adaptive Radiation Therapy (ART) based on plan library invoking, comprising:
acquiring a medical image of the day and a target plan library of a target patient, wherein the target plan library comprises a plurality of groups of images of the target patient and a radiation therapy plan corresponding to each set of images; and
determining the radiation therapy plan corresponding to the target patient according to the medical image of the day and the target plan library;
wherein the acquiring a medical image of the day and a target plan library of a target patient comprises:
determining whether there is an offline plan library corresponding to the target patient, wherein the offline plan library comprises a plurality of groups of images of the target patient and a radiation therapy plan corresponding to each set of images;
when there is the offline plan library corresponding to the target patient, performing image registration on the medical image of the day and the plurality of groups of images in the offline plan library to obtain a deformation field; and
when a deformation quantity of the deformation field is less than a preset threshold I, using the offline plan library as the target plan library, or updating the radiation therapy plan of the offline plan library according to the deformation quantity to obtain the target plan library.
