同位素扫描医学图象的三维重建

The 3-D Reconstruction of Medical Radioisotope-scan Images

本文提出了一个图象处理系统,通过同位素扫描仪器获得的人体正、侧投影图象,实现人体器官的三维图象重建。文中介绍了改进的最小费用流算法实现图象重建的原理,以及实际处理中正、侧面图象配准等问题的处理方法。

This paper presents an image processing system for the 3-D reconstruction of medicalradioisotope-scan organ images from their two orthogonal projections. A new minimum cost network flow ap-proach is described for the reconstruction Also, some problems in actual situation, such as the registraion betweenthe front and side- view projections, are discussed here.
