摘要/Abstract

摘要： 提出一种自动检测心脏门控图像左心室边缘的算法. 该算法依据核医学心脏门控图像灰度分布的特点, 采用模糊增强的方法增强图像的左心室区域, 利用增强后的图像实现左心室边缘自动检测. 该算法对于左右心室分得不开的核医学心脏门控图像也能正确检测出左心室的边缘.

关键词: 图像检测, 模糊增强, 边缘检测

Abstract: A fuzzy-based automatic boundary detection algorithm for cardiac left ventricular (LV) of nuclear medical images is described.The proposed method is a fuzzy-base approach in which the images are enhanced with fuzzy algorithm according to the gray distribution of gated cardiac images of nuclear medicine.Then the boundary of LV are detected automatically by using the enhanced images.The algorithm is effective even if the left ventricular and right ventricular of the gated cardiac images are not apart from each other very well.

Key words: image detection, fuzzy enhancement, boundary detection
