Simulated dMRI images and ground truth of random fiber phantoms in various configurations

This archive contains simulated dMRI images of random fiber phantoms in various configurations created with Fiberfox and other tools available in MITK Diffusion (http://mitk.org/wiki/DiffusionImaging). RandomFibers_Example.png illustrates one of the random fiber configurations used for these phantoms.

If you are using any of these datasets or the tools used to generate them, please don't forget to cite the dataset itself as well as other relevant publications.

Each subfolder contains the following elements:
The simulated dMRI image with b-values and gradient directions: dwi.nii.gz, dwi.bvals, dwi.bvecs
The fibers used for simulation: AllBundles.fib (binary vtk format)
parameters.ffp: Fiberfox simulation parameters
parameters.ffp.bvals: b-value file for Fiberfox simulation
parameters.ffp.bvecs: gradient vector file for Fiberfox simulation
parameters.ffp_VOLUME1.nii.gz: fiber compartment volume fraction map for Fiberfox simulation
The logfile detailing all steps of the generation process of the respective phantom: LOGFILE.json

bundles: folder containing the individual fiber bundles (binary vtk format .fib)
centroids: folder containing the centerlines of each bundle
masks: folder containing the binary envelope of each bundle
peaks: folder containing the principal fiber direction image (peaks) of each bundle
