双源螺旋CT在心脏冠状动脉成像中的应用研究

Evaluation of Coronary Artery Visualization by Dual Source Computed Tomography

双源CT(DSCT)是CT发展进程中涌现出的一项最新技术。它是由成90°安装在机架上的两套球管及与其相对应的探测器阵列组成。这一新颖设计赋予DSCT与其他普通机型无法比拟的极高的时间、空间分辨率,使其可以胜任其他机型难以完成的全心率心脏冠状动脉成像。它的出现使CT技术在心血管疾病的检查中临床适应证更宽,诊断更加准确,应用前景十分广阔。

Dual source computed tomography is the nwest technology in the CT developing procedure. It is equipped with two X-ray tube and corresponding detector,which mounted onto the rotating gantry with an angle offset of 90°. This novelty design ensures DSCT obtains more excellent time and spitial resolution , which make it competent for coronary artery visualization at all heart rate. Emergende of DSCT made CT coronary artery visualization easier and more robust, it has abrilliant practical future.
