Tri-Linear Regulation of Diffusion Tensor Field for WM Fiber Tracking

Abstract:

In this paper we present a method for regulating diffusion tensor magnetic resonance (DT-MRI) data. The method is divided in two steps. First, decomposed diffusion tensor and found out the tensors whose eigenvalue was non-positive. The second step was to apply tri-linear interpolation to regularize the diffusion tensor field. We show that the process is a convenient framework to regulate DT-MR data. Both steps are illustrated on real diffusion tensor magnetic resonance data.
