![]() The right ventricle closes the loop by pumping the blood to the lung for oxygenation, which then flows back to the left atrium. The left ventricle (LV) pumps blood to the systemic circulation through the aorta, and deoxygenated blood returns to the right atrium. The human heart is a complex organ in terms of both two atria, and two ventricles on the left and right side. Substantially, feedback from cardiologists have confirmed the practical utility of integrating these features for the purpose of computer-aided diagnosis of ischemic heart disease. The following visual information is presented: (1) Anatomy from CT imaging: geometric modeling and visualization of cardiac anatomy, including four heart chambers, left and right ventricular outflow tracts, and coronary arteries (2) Function from CT imaging: motion modeling, strain calculation, and visualization of four heart chambers (3) Physiology from CT imaging: quantification and visualization of myocardial perfusion and contextual integration with coronary artery anatomy (4) Physiology from computer simulation: computation and visualization of hemodynamics (e.g., coronary blood velocity, pressure, shear stress, and fluid forces on the vessel wall). We introduce a new computer-aided diagnosis framework, which allows for comprehensive modeling and visualization of cardiac anatomy and physiology from CT imaging data and computer simulations, with a primary focus on ischemic heart disease. ![]() The current tools are not adequately integrated to visualize anatomic and physiologic data from a complete yet focused perspective. However, it remains challenging to gain useful information from the large amount of high-dimensional diverse data. CT imaging and computer simulations provide valuable and complementary data for this purpose. In clinical cardiology, both anatomy and physiology are needed to diagnose cardiac pathologies.
