Tensor Field Regularisation for DT-MR Images
نویسندگان
چکیده
We present here a method to regularise diffusion tensor magnetic resonance images. The scheme is divided in two steps: a restoration of the principal diffusion direction (PDD) field, and a regularisation of the eigenvalue maps. The first step is based on a recent variational approach to restore direction maps, and the second step consists of an anisotropic diffusion scheme driven by the restored tensor. Results from experiments on both simulated and real data are shown.

Diffusion-tensor image registration
In this chapter, we introduce the problem of registering diffusion tensor magnetic resonance (DT-MR) images. The registration task for these images is made challenging by the orientational information they contain, which is affected by the registration transformation. This information about orientation and other aspects of the diffusion tensor are exploited in the development of similarity meas...
متن کاملEfficient Tracking of MR Tensor Fields Using a Multilayer Neural Network
In this paper, a recently developed fiber tracking algorithm to be used with diffusion tensor (DT) fields acquired via magnetic resonance imaging (MRI) is improved and applied to real brain DT-MR images. The method performs satisfactorily in regions where branching and crossing fibers exist and offers the capability of reporting a probability value for the computed tracts. This certainty figure...
متن کاملComparison between fourth and second order DT-MR image segmentations
A second order tensor is usually used to describe the diffusion of water for each voxel within a Diffusion Tensor Magnetic Resonance (DT-MR) images. However, a second order tensor approximation fails to accurately represent complex local tissue structures such as crossing fibers. Therefore, higher order tensors are used to represent more complex diffusivity profiles. In this work we examine and...

INTRODUCTION Diffusion tensor MRI (DT-MRI) provides a discrete representation of the diffusion tensor field ofwater in living tissues. A graphical means to display the diffusion tensor field, '[\]is to construct diffusion ellipsoid maps or images (1). Moreover, from the diffusion tensor field, one can infer the fiber-tract direction field in some anisotropic tissues (1). 1n white matter and ske...
متن کاملA Fuzzy, Nonparametric Segmentation Framework for DTI and MRI Analysis
This paper presents a novel statistical fuzzy-segmentation method for diffusion tensor (DT) images and magnetic resonance (MR) images. Typical fuzzy-segmentation schemes, e.g. those based on fuzzyC-means (FCM), incorporate Gaussian class models which are inherently biased towards ellipsoidal clusters. Fiber bundles in DT images, however, comprise tensors that can inherently lie on more-complex ...
