电子束CT扫描机电子束CT扫描机 CT设备的类型之一。通过电子枪发射电子束产生旋转X线源进行扫描的CT设备。于80年代中期设计,也称为电影CT(cine CT)、超(高)速CT(ultrafast CT,UFCT)或第五代CT机,为主要用于心脏检查、兼可用于一般检查目的的全身CT设备。这种设备用电子枪和钨靶环取代了机械性旋转的X线管,不存在热负荷限度问题。最快扫描速度达0.05秒,因此又被称为超(高)速CT。基本工作原理是:电子枪发射电子束经聚焦线圈和偏转线圈聚焦、转向后投射于机架内4排钨靶环上,产生旋转发射的X线束进行层面扫描,机架内固定排列成环形(210°)的集成闪烁晶体二极管探测器阵列接收透射的X线光子,再经数据采集系统数字化和快速原始数据平均器处理等过程,最终产生断层层面重建影像。这种设备具有两种基本扫描操作方式:①单层面高分辨方式,使用单靶环一次获取一幅3~10mm层厚、512×512矩阵图像,扫描速度0.1~0.2秒,重建速度5秒,用于头、体一般检查。连续进床式扫描可进行体积方式扫描即螺旋扫描,具有三维成像(3D-CT)、CT血管成像(CTA)等功能,可进行冠状动脉小钙斑的检查。②多层面方式,4个靶环连续扫描而不进床,每环同时获两个层面,速度0.05秒,共获8层10mm层厚图像,可重复扫描。又分为流动方式和电影方式,前者用于观察血管、组织内对比剂灌注、扩散的动态变化及血流量等方面的研究,后者可用于心脏结构和功能、关节运动、气道功能等多方面的研究。
