Abstract: The disclosure relates to a system and method for adapt a treatment plan. The method may include: obtaining an initial treatment plan of a region of interest, wherein the initial treatment plan includes a first initial treatment fraction and a second initial treatment fraction; causing a radiation treatment device to deliver the first initial treatment fraction; obtaining a treatment record related to the first initial treatment fraction; and generating an updated second treatment fraction based on the second initial treatment fraction and the treatment record.

Abstract: This present disclosure provides methods and systems processing a three-dimensional image. The method may include: generating a three-dimensional medical image of a target object based on medical imaging data of the target object, and displaying the three-dimensional medical image in a three-dimensional space; obtaining one or more processing instructions of a user; and generating a target medical model by contouring, in the three-dimensional space, based on the one or more processing instructions, the three-dimensional medical image. The three-dimensional medical image may be generated based on medical imaging data of the target object. The target medical model may include three-dimensional contour information.

Abstract: A system for data synchronization is provided. The system may include a workstation, a user terminal, and a storage device that is accessible to the user terminal and the workstation. The workstation may be configured to generate an identifier relating to a subject. The identifier may point to a data address in the storage device that stores data relating to the subject. The user terminal may be configured to acquire image data of the subject from the data address based on the identifier, receive a user input with respect to the image data of the subject, and update the image data stored in the data address based on the user input.
