70年代初,电子计算机装备的体层摄影(Computerized tomography x-Ray,简称 x 线 CT 成象)新技术问世。70年代后期,由于门控技术、超快速摄影技术、放射性核素显象和 CT 技术的结合,x 线 CT 成象越来越多地用于心血管疾病诊断。本文主要介绍该项技术在心血管疾病诊断中的应用进展。一、x 线 CT 成象技术的进展和 x 线摄片一样,电子计算机装备的体 The early 70s, the electronic computer equipment tomography (Computerized tomography x-Ray, referred to as x-ray CT imaging) new technology come out. In the late 1970s, x-ray computed tomography was increasingly used in the diagnosis of cardiovascular disease due to the combination of gating techniques, ultra-fast photographic techniques, radionuclide imaging, and CT techniques. This article describes the application of this technology in the diagnosis of cardiovascular disease. First, the progress of x-ray CT imaging technology and x-ray film, the body of electronic computer equipment
