Shape-based MRI data segmentation in the presence of intensity inhomogeneities using level sets
收藏 引用
International Congress Series 2004年 第C期1268卷 213-218页
作者: Hassan, Hossam Farag, Aly A. Electrical and Computer Engineering Computer Vision and Image Processing Laboratory University of Louisville Louisville KY 40292 403 Lutz Hall Building Universit United States
Magnetic resonance imaging (MRI) intensity inhomogeneities can be attributed to imperfections in the RF coils or some problems associated with the acquisition sequences. The result is a slowly varying shading artifact... 详细信息
