  • Abstract
    In diffusion tensor magnetic resonance imaging (DT-MRI), each voxel is assigned a tensor that describes local water diffusion. In this study, the eigenvectors and eigenvalues of the diffusion tensor D are analyzed based on stack linked list algorithm. The aim of the study is to develop a reliable and rapid tractography algorithm. In our sample, 60 diffusion weighted human brain images and a null image namely the T2 image creating a set of intensity images of size 256 times 256 times 60 times 30 have been examined. The eigensystem of D is calculated in every pixel, apparent diffusion coefficient ADC is represented with respect to D. The idea of the proposed method is to accomplish the fiber pathway by starting from a single, selected node taking every node in other words all the information of the eigensystem of the whole brain into account. Developing a reliable and rapid fiber tracking algorithm for the clinical use regarding to the verified results is the future study of the work in progress.
