Iterative Reconstruction in Diffusion Tensor Tomography Using Total Variation Regularization on Reconstructed Eigenvalue and Tensor Component Images
نویسندگان
چکیده
The regularized iterative reconstruction of the tensor field in diffusion tensor tomography magnetic resonance imaging was investigated. The total variation constraints on eigenvalue and tensor component images of the diffusion tensor were explored. A computer generated phantom was used to simulate the diffusion tensor in a cardiac MRI study in which the diffusion model depended upon the fiber structure of the myocardium. Computer simulations verify that the regularized methods provide improved reconstruction of the tensor principal directions. A reconstruction from experimentally acquired data is also presented. .

متن کاملTensor Based Second Order Variational Model for Image Reconstruction
Second order total variation (SOTV) models have advantages for image reconstruction over their first order counterparts including their ability to remove the staircase artefact in the reconstructed image, but they tend to blur the reconstructed image. To overcome this drawback, we introduce a new Tensor Weighted Second Order (TWSO) model for image reconstruction. Specifically, we develop a nove...
