多层螺旋CT(多层螺旋CT、多层螺旋CT)代表了CT技术的突破。它将CT从一种横断面技术转变为一种真正的3D成像方式，允许任意切面以及出色的数据体3D显示。多层CT扫描仪提供了极大的性能提升，可用于缩短扫描时间、减少断层准直或大幅增加扫描长度。下面的文章将提供多层螺旋CT扫描原理的概述。它描述了各种探测器系统，并介绍了最重要的采集和重建参数。本文描述了如何利用多层螺旋CT的3D能力重建多平面重建，同时将辐射暴露保持在最低限度。(C)2002爱思唯尔科学爱尔兰有限公司。保留所有权利。
Multidetector CT (MDCT, multislice CT, multidetector-row CT, multisection CT) represents a breakthrough in CT technology. It has transformed CT from an transaxial cross-sectional technique into a true 3D imaging modality that allows for arbitrary cut planes as well as excellent 3D displays of the data volume. Multislice CT scanners provide a huge gain in performance that can be used to reduce scan time, to reduce section collimation, or to increase scan length substantially. The following article will provide an overview of the principles of multislice CT scanning. It describes the various detector systems and gives an introduction to the most important acquisition and reconstruction parameters. The article describes how reconstruction of thick multiplanar reformations can be used to take advantage of the 3D capabilities of multislice CT while keep radiation exposure to a minimum.
