A method of x-ray fluoroscopy images a region of interest at distinct first and second imaging projection angles using digital subtraction x-ray fluoroscopic imaging with a fiducial marker board positioned in a field of view containing the region of interest to produce first and second sets of images. Image segmentation information is determined to identify an anatomical feature in the region of interest imaged in the first set of images and the second set of images. The region of interest is then imaged using x-ray fluoroscopic imaging, again with the fiducial marker board positioned in a third field of view containing the region of interest, but without digital subtraction, to produce a third set of images. A virtual image of the anatomical feature is projected onto the third set of images, computed from the image segmentation information and from a predetermined geometric relationship of markers within the fiducial marker board.
