Visualization of Coronary Arteries from Intravenous AngiogramsUnder most circumstances, the coronary arteries are not satisfactorily visualized in intravenous angiograms. The objective of this study is to develop computer image enhancement methods that will improve the quality of the latent coronary images to a degree sufficient to detect an obstructive lesion. Such a technique, if successful, could be used as a first step alternative to conventional coronary angiography for individuals with ambiguous noninvasive cardiac tests. The determination of no lesion from the intravenous procedure would relieve the need for the conventional angiogram, while verification of an obstructive lesion could be followed by a conventional angiogram. The nature of the imaging problem and a description of the methods and initial processing results are described in this paper.
