We present an interactive graphical tool, Fiberfox, to generate arbitrary fiber configurations and corresponding diffusion weighted images (DWI). The intuitive user interface allows for the generation of any number of straight, bended, crossing, kissing, twisting and fanning fiber bundles, simply by placing 3D-ROIs used as waypoints for the synthetic fibers. From these fibers, a DWI is calculated applying a user defined number of gradient directions, b-value, SNR, image size and spacing. Fiberfox is implemented in the open source medical imaging interaction toolkit (MITK) and will also be available as free download included in the next release of MITK Diffusion.
