1. A method for removing contrast enhanced regions from acquired dual energy contrast-enhanced CT images, the steps comprising: a) segmenting the acquired dual energy CT images into high and low energy contrast images and contrast complement images; b) performing a dual energy subtraction of the high and low energy contrast images to yield a dual energy subtraction image, wherein a null signal is produced by the contrast agent; c) producing a subject localizer mask from the dual energy subtraction image identifying pixel locations of a subject; d) multiplying an acquired image by the subject localizer mask to produce an image of the subject; and e) combining the image of the subject with a contrast complement image.
