  • Bruker format support.
  • Small change in median filtering.
  • Minor bug fixes.
  • Linux version.

DKE 2.5.1 (December 27, 2012)

  • The length of user-defined gradiant sets was not recognized properly.

DKE (September 24, 2012)

  • Vista read-only issue fixed.

DKE Modules

The DKE Fiber Tractography (FT) Module performs white matter FT using the DKI approximation of the diffusion orientation distribution function (dODF). This module uses the diffusion and kurtosis tensors from DKE and should be run with DKE version 2.6 or later. 

DKE requires the installation of the MATLAB Compiler Runtime 2012a (MCR)

Example Dataset

If you don't have a DKI dataset, you can download the example dataset from our DKE project on NITRC. The DKI files are in DICOM and NIfTI format. You can also download parametric maps and tensors output from DKE.
