Summary form only given. A synchrotron-based medical imaging facility has been built at the National Synchrotron Light Source. It will allow imaging of the coronary arteries using a venous instead of an arterial injection of contrast agent. Two monochromatic fan X-ray beams (at energies around the iodine K edge) are used to take sets of images. The system is described and results with five patients are presented. possible system upgrades to improve image contrast and spatial resolution and to decrease the image acquisition time have been considered. >
