| Sumario: | Cardiac computed tomography (CT) and its main clinical application, coronary CT angiography, have made major progress during the past years. Advances were driven by progress in CT hardware technology and CT image reconstruction and processing software. Technical innovations have successfully been used to lower the radiation exposure of coronary CT angiography and to improve image quality, especially in challenging situations, such as individuals with high heart rates or severe calcification. Some of the most important recent contributions have been the development of area detectors, dual-source CT, and the introduction of iterative reconstruction algorithms.
