| 摘 要： | 提出了一种从核磁共振图像中自动分割大脑结构的方法。根据大脑解剖学知识构造了灰度信息、相对距离信息和相对方向信息等模型，并组合成一个模糊专家系统。为了提高分割结果的精确性，各模型信息被模糊化并经过数据融合以得到高的分割精度，对多组大脑核磁共振图像进行分割的实验结果证明了该算法具有良好的分割效果。

| Abstract: | An automated method for segmentation of subcortical s tr uctures in MR head scans was presented. Features extracted from the images, name ly, intensities of the structures and relative distances and directions, were pr ocessed in a fuzzy framework. To overcome the imprecision and uncertainty, the f eatures were made fuzzy and fused together to maximize the detection accuracy. E xperiments on an ensemble of MR head scans show that this approach is effective. |
