dMRI FiberCup simulations Ground truth fibers of the replicated FiberCup dataset

pneher@stage.nitrcce.org (Peter Neher) — Wed, 01 Apr 2015 7:49:00 GMT

This package contains the ground truth fibers of the replicated FiberCup dataset. The ground truth fibers are provided in TrackVis (.trk) and VTK (.vtk, .fib) file format.

Note that the fibers are in the space of the original FiberCup file. To match the simulated FiberCup datasets, the fibers have to be mirrored sagitally and coronally (possible e.g. using MITK Diffusion).

dMRI FiberCup simulations Fiberfox replications of the FiberCup datasets

pneher@stage.nitrcce.org (Peter Neher) — Thu, 08 Aug 2013 10:01:00 GMT

This archive contains a series of synthetic diffusion weighted images with a structure similar to the well-known FiberCup phantom. A description of the individual files can be found below. All files have been created with the Fiberfox tool that is included in MITK Diffusion. MITK Diffusion is available as free download on
http://www.nitrc.org/projects/mitk-diffusion/
and
http://www.mitk.org/DiffusionImaging

For a detailed reference of Fiberfox, the file creation and usage please refer to: ******* publication currently in review ********
