The FiberCup diffusion phantom, designed to mimic a coronal cross-section of the human brain, was developed for quantitative evaluation of multi-fiber diffusion models and tractography algorithms. The data available, however, is insufficient to allow comparison against all diffusion-weighted MRI methods, such as Diffusion Spectrum Imaging. We outline development of an accurate and flexible q-Space simulation of the FiberCup phantom, and illustrate its versatility by synthesizing data and processing it according to Diffusion Tensor Imaging, Diffusion Spectrum Imaging, Constrained Spherical Deconvolution and analytical Q-Ball Imaging methods. Results of tractography are presented.
