Noninvasive Detection and Quantification of Atherosclerotic Lesions in Peripheral and Coronary Arteries

摘要

This report describes an analysis and evaluation of methods for digital subtraction angiography with the ultimate goal of imaging coronary arteries. Evaluation of subtraction methods, spatial resolution requirements and optimum detection and quantization of vessel stenosis are included in this study. A new subtraction method using dual energy for in vivo vascular imaging is described.
