Brain MRI simulations of 99 subjects

This archive contains simulated MRI images (T1, T2, dMRI) of 99 healthy subjects as well as corresponding reference fiber tracts used for the MRI simulation. The archive is primarily intended for the training and validation of fiber tractography methods but is well suited for many other tasks in the area o diffusion-weighted MRI image processing.

The simulation was performed using the Fiberfox dMRI simulation tool included in MITK Diffusion. Fiberfox uses reference fiber tracts and volume fraction maps as input to simulate the actual k-space acquisition. This enables highly realistic looking image contrasts and artifacts. The reference data was created on the basis of 99 unrelated subjects from the HCP young adult dataset.
