Review for the study of image reconstruction algorithms in Voluming CT

摘要: 体积CT是继断层CT发展而来的一种高新技术。它具有获取投影数据的速度快、X射线利用率高、成象结果空间分辨率各向同性等优点,因而将成为用于医学影象诊断、工业无损检测等领域的更为有效的手段之一。本文对体积CT技术的发展历史、主要特点、算法分类及未来发展等进行了系统地回顾、分析和展望。

Abstract: Voluming CT which is studied later than cross-sectional CT belongs to the field of high-new technology. Compared to cross-sectional CT, it has a lot of advantages, such as the rate of obtaining projections, X-ray utilization ratio and the isotropy of the spatial resolution and density resolution in 3D object. Voluming CT will became one of the more effective methods in medical imaging and industrial nondestructive test. In this paper we introduce the history, the principal characteristics, the algorithmic classifies and the future prospects of the Voluming CT.
