ABSTRACT:
Projection measurements are made at different parts of the X-ray energy spectrum. These measurements are processed to obtain image data with the soft tissue component eliminated. The processed image data is obtained before and after the administration of a contrast agent. The two sets of processed image data are combined to obtain an isolated image of the contrast agent which is immune to motion of soft tissue.
