Abstract

A method of generating images of a portion of a body includes introducing a contrast agent into the body, generating a first set of image data using radiation at a first energy level after the contrast agent is introduced into the body, generating a second set of image data using radiation at a second energy level after the contrast agent is introduced into the body, and creating a volumetric composite image using the first and the second sets of image data.
