Semi-Automatic 4D Fuzzy Connectedness Segmentation of Heart Ventricles in Cine MRI.

The volumes of the left and right cardiac ventricles are important indexes for several cardiovascular diseases. In this paper, a semiautomatic algorithm based on 4D fuzzy connectedness is proposed for segmenting the cardiac ventricles in arbitrarily oriented cardiac cine MR images. The segmentation of the left ventricle was evaluated using 45 short axis images and a visual assessment of right ventricle segmentation was performed.
