1. A method for determining a target region of interest (ROI) for image registration, implemented on a computing device having at least one processor and at least one non-transitory storage medium, the method comprising:
obtaining a target image of a subject including a target portion of the subject;
obtaining feature information related to movements of one or more feature portions of the subject, the feature information related to a movement of a feature portion of the one or more feature portions including at least one of a moving range related to the feature portion or whether the movement of the feature portion affects a position of the target portion of the subject;
identifying, from the one or more feature portions, one or more reference portions of the subject based on the feature information of the one or more feature portions, wherein a position of the target portion of the subject is unrelated to a movement of the one or more reference portions; and
determining, in the target image, the target ROI based on a portion of the feature information corresponding to the one or more reference portions, wherein the target ROI does not include a pixel or voxel associated with the one or more reference portions.
