Abstract

It has been demonstrated previously (see E. L. Ritman and A. A. Bove, in State of the Art in Quantitative Coronary Arteriography, pp. 67-78, 1986) that coronary artery anatomy can be visualized using high-speed, volume-scanning X-ray CT (computed tomography). In the current study it is demonstrates that local image reconstruction (i.e., the reconstruction kernel is approximately 2 + mm long), as distinct from more conventional global image reconstruction (i.e, 200 + mm kernel length), has the advantage of reducing the need for operator interactive image processing. In addition, the local reconstruction algorithm eliminates the need for recording the X-ray projection data over the full transaxial extent of the thorax because it requires only the X-ray attenuation data over the region of the heart. This latter aspect reduces the dynamic range requirements for the sensors and could reduce total x-ray exposure.
