一种基于最短路径思想的交互式MR图像壳核分割方法

o accurately segment putamen with weak edge of basal ganglia region in brain MR images, a shortest path based interactive segmentation method is proposed in this paper. Considering anatomical features of putamen, the cost function of the method uses weight coefficients in sub regions and orientations, and the shortest path search region is restrained, so that the weak edge of putamen can be identified effectively which solved the problem of Live-wire in detecting edge of putamen. Great deals of experiments demonstrate that proposed method can realize fast segment with accuracy and robustness for putamen.
