1. A method for radiological imaging, the method comprising: receiving a series of two-dimensional radiological images that form a three-dimensional radiological image, wherein the three-dimensional radiological image includes a first body part, a second body part, and a functional portion, and wherein the functional portion spans across each of the at least two body parts; identifying a plurality of sub-portions in a corresponding plurality of the two-dimensional radiological images in each of the first body part and the second body part; grouping the plurality of sub-portions into the functional portion; and displaying on a display the functional portion, wherein image data corresponding to the first body part is generated from a first radiological procedure and wherein image data corresponding to the second body part is generated from a second radiological procedure.
