Claim 17:
18. A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
obtaining an initial image of an object acquired by performing a preliminary scan on the object using an imaging device;
obtaining geometric information of a region of interest (ROI) of the object in the initial image, the geometric information of the ROI including a size and shape of the ROI;
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.
