Left ventricle(LV) segmentation is a prerequisite step of evaluation of LV structure and function, which plays an important role in the diagnosis and treatment of cardiovascular diseases. In this paper, we propose a method to segment endocardium and epicardium of LV using convolution neural network combined with active contour model and tensor voting. A fully convolution neural network (FCN) named...
A novel approach based on graph matching for myocardial motion estimation using cine MRI is presented in this paper. The dissimilarity measure between nodes and that between edges are defined to construct a cost function to measure the dissimilarity between two graphs. The sparsity constraint and affine constraint are introduced into the cost function. The alternating direction method of multipliers...
