One of the critical components for effective cardiac computed tomography (CT) application is a fully integrated and optimized image visualization, postprocessing, and analysis tool. Study of native axial images is not enough to assess all cardiac structures, especially coronary arteries (Fig. 1). Postprocessing is critical to visualize the arterial system and heart chambers. Specific tools have been designed and are still under development. They require a powerful postprocessing workstation. A complete study of coronary arteries needs to follow a systematic protocol including various postprocessing tools.
