Abstract
To produce a black body angiographic image representation of a subject (), an imaging scanner () acquires imaging data that includes black blood vascular contrast. A reconstruction processor () reconstructs a gray scale image representation () from the imaging data. A post-acquisition processor () transforms () the image representation () into a pre-processed image representation (). The processor () assigns () each image element into one of a plurality of classes including a black class corresponding to imaged vascular structures, bone, and air, and a gray class corresponding to other non-vascular tissues. The processor () averages () intensities of the image elements of the gray class to obtain a mean gray intensity value (), and replaces () the values of image elements comprising non-vascular structures of the black class with the mean gray intensity value.
