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.
心脏计算机断层扫描（CT）及其主要临床应用——冠状动脉 CT 血管造影，在过去几年中取得了重大进展。这得益于 CT 硬件技术、CT 图像重建和处理软件的进步。技术创新成功降低了冠状动脉 CT 血管造影的辐射剂量，并提高了图像质量，尤其是在高心率或严重钙化等具有挑战性的情况下。最近的一些重要进展包括：面探测器的发展、双源 CT 以及迭代重建算法的引入。
