Abstract

A simulation study of the EM algorithm for image reconstruction in PET is discussed. Recently a method to stop the iterations before the image quality starts to deteriorate has been proposed by G. Kontaxakis and G. Tzanakos (IEEE Nucl. Sci. Symp., 1992). Here, a further study of the method is presented in an effort to apply the stopping rule to individual elements or groups of elements of the image vector.<>

进一步研究了EM算法的停止规则

对PET图像重建中的EM算法进行了仿真研究。最近，一种在图像质量开始恶化之前停止迭代的方法被G. Kontaxakis和G. Tzanakos (IEEE核)提出。科学。计算机协会。, 1992)。本文提出了对该方法的进一步研究，试图将停止规则应用于图像矢量的单个元素或元素组。
