Abstract
A system and method includes reception of first two-dimensional projection images of a patient volume, each of the first two-dimensional projection images having been acquired from substantially a respective one of a plurality of projection angles during presence of at least a portion of contrast medium in arteries within the patient volume, reception of second two-dimensional projection images of the patient volume, each of the second two-dimensional projection images having been acquired from substantially a respective one of the plurality of projection angles during presence of at least a portion of the contrast medium in veins within the patient volume, generation, for each of the plurality of projection angles, of a composite two-dimensional image based on one of the first two-dimensional projection images acquired from substantially the projection angle and one of the second two-dimensional projection images acquired from substantially the projection angle, generation of a three-dimensional image based on the generated composite two-dimensional images, and display of an image based on the three-dimensional image.
