Geometric feature-based multimodal image registration of contrast-enhancedcardiac CT with gated myocardial perfusion SPECT

摘要

Purpose:Cardiac computed tomography (CT) and single photon emission computed tomography (SPECT) provide clinically complementary information in the diagnosis of coronary artery disease (CAD). Fused anatomical and physiological data acquired sequentially on separate scanners can be coregistered to accurately diagnose CAD in specific coronary vessels.
