Create realistic Diffusion MRI Phantom

Phantomαs is an open-source library written in C/Python designed to create realistic phantoms in structural and diffusion magnetic resonance imaging (MRI). An early version of Phantomαs was used to create the testing and training data of the 2nd HARDI Reconstruction Challenge, organized at ISBI 2013.
