Abstract

The introduction of spiral and more specifically multidetector CT scanners has provided unique opportunities in the field of CT angiography. It has also stressed the need of a basic knowledge of post-processing 3D imaging techniques to obtain maximum information of the CT data set. Aim of this article is to give a basic review of technical issues concerning CT angiography, with special attention to 3D imaging techniques such as surface shaded display (SSD), maximum intensity projection (MIP) and volume rendering (VR).

摘要

螺旋CT扫描仪，尤其是多排探测器CT扫描仪的引入，为CT血管造影领域带来了独特的机遇。这也凸显了掌握后处理三维成像技术基础知识的必要性，以便从CT数据集中获取最大信息量。本文旨在对CT血管造影的技术问题进行基础综述，特别关注表面阴影显示（SSD）、最大密度投影（MIP）和容积再现（VR）等三维成像技术。
