Since 1958, catheter angiography has assumed the role of gold standard for vascular imaging, despite the invasive nature of the procedure. Less invasive techniques for vascular imaging, such as computed tomographic angiography (CTA), have been developed and have matured in conjunction with developments in catheter arteriography. In a few cases, such as imaging, the aorta and the pulmonary arteries, CTA has supplanted catheter angiography as the gold standard. The expanding role of CTA emphasizes the need for deep, broad-based understanding of physical principles. This review describes CT hardware and associated software for angiography. The fundamentals of CTA physics are complemented with several clinical examples.
自1958年以来，尽管导管血管造影术具有侵入性，但它一直是血管成像的金标准。血管成像的侵入性较小的技术，如计算机断层血管造影（CTA），已随着导管动脉造影术的发展而得到开发并成熟。在少数情况下，如对主动脉和肺动脉进行成像时，CTA已取代导管血管造影术成为金标准。CTA作用的不断扩大凸显了深入、全面理解物理原理的必要性。本综述描述了用于血管造影的CT硬件及相关软件。CTA物理基础辅以若干临床实例。
