Claim 0:
1. A system for positioning a region of interest (ROI) of an object, comprising:
at least one storage device including a set of instructions; and
at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is directed to perform operations including:
obtaining an initial image of the object acquired by performing a preliminary scan on the object using an imaging device;
obtaining geometric information of the ROI in the initial image, the geometric information of the ROI includes a size and a shape of the ROI; and
obtaining an image of the object that is acquired by performing, using the imaging device, a tracker scan on the object to monitor a concentration of a contrast agent in the ROI;
obtaining feature information of the ROI in the object based on the image, the feature information of the ROI including imaging parameter information associated with the ROI, the imaging parameter information corresponding to the concentration of the contrast agent; and
determining position information of the ROI in the image using a positioning model based on the geometric information of the ROI in the initial image and the feature information of the ROI.
