Abstract
(EN)
A method for reconstructing list mode data comprises: reconstructing all list mode data of a list mode data set (30, 160) to generate a first reconstructed image (32, 62); selecting a sub-set of the list mode data set; and reconstructing the sub-set of the list mode data set to generate an enhanced reconstructed image (84, 86). An image generation system comprises: a reconstruction module (24) configured to perform a standard reconstruction of a list mode data set to generate a standard reconstructed image (32, 62); and a re-reconstruction module (24, 70, 80, 82, 150, 152, 154) configured to perform a reconstruction other than the standard reconstruction of at least a portion of the list mode data set to generate an enhanced reconstructed image (84, 86).

一种用于重建列表模式数据的方法,包括:重建列表模式数据集(30、160)的全部的列表模式数据以生成第一重建图像(32、62);选择所述列表模式数据集的子集;以及重建所述列表模式数据集的子集以生成增强的重建图像(84、86)。一种图像生成系统,包括:重建模块(24),其被配置成执行列表模式数据集的标准重建以生成标准的重建图像(32、62);以及再重建模块(24、70、80、82、150、152、154),其被配置成对所述列表模式数据集的至少部分执行除所述标准重建之外的重建以生成增强的重建图像(84、86)。
