    • The present invention is intended to provide an image reconstruction method based on an iterative reconstruction technique and characterized by a short image reconstruction time, a small memory capacity, and high image quality. The image reconstruction method comprises the steps of: constructing a system model that has a plurality of concentric rings each segmented into a plurality of sectors; constructing a system matrix associated with one view, by using some of all the sectors constituting the system model, the some of all sectors being located on respective projection lines concerning the one view; creating a system matrix associated with another view, by transforming the system matrix associated with the one view; reconstructing an image through iterative reconstruction by using the system matrix and projection data; and transforming the image into an image composed of rectangular pixels.
    • 本发明旨在提供一种基于迭代重建技术的图像重建方法,其特征在于短图像重建时间,小存储容量和高图像质量。 图像重建方法包括以下步骤:构建具有多个同心环的系统模型,每个同心环分成多个扇区; 通过使用构成系统模型的所有扇区中的一些构造与一个视图相关联的系统矩阵,所有扇区中的一些位于关于一个视图的相应投影线上; 通过转换与一个视图相关联的系统矩阵来创建与另一个视图相关联的系统矩阵; 通过使用系统矩阵和投影数据通过迭代重建来重建图像; 并将图像变换为由矩形像素构成的图像。
