基于模糊的核医学心脏门控图像左心室边缘自动检测

A Fuzzy Based Automatic Cardiac LV Boundary Detection of Nuclear Medical Images

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 .

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.
