当前图像重建研究中的几个热点

Research Highlight of Image Reconstruction Today

在当前的图像处理研究中，图像重建是一个热点，其中研究方向又可归结为以下几个方面：（１）利用时频约束去除重建前和重建后的噪声。（２）运动器官的断层像重建研究。（３）不完全投影数据下的重建。（４）直接体积重建及三维显示。（５）非Ｘ 线ＣＴ 的研究。（６）并行计算ＣＴ 的研究。本文对这几方面作了简要的概述。

In today's image processing researches, image reconstruction is a highlight. It includes the following several aspects:(1) reducing noise before reconstruction or after reconstruction under time frequency constraints;(2) researches for reconstruction of motion organ;(3)image reconstruction from incomplete projection data; (4) direct volume reconstruction and 3 D image rendering; (5) researches for non X ray CT; (6) researches for parallel processing system of CT. In this paper, an introduction to these aspects is given.
