Rigid DIFFUSION PHANTOM: Acquisition and simulation

Diffusion tensor imaging has already been a popular imaging modality for clinical researches. However, to setup an imaging protocol is not straightforward. This problem is critical issue for multi-center studies. We developed anisotropy phantoms and examined the feasibility of using water-filled arrays of channeled silicon plates. Various channel sizes were tested to optimize the diffusion and anisotropy properties. We succeeded in producing a phantom with high anisotropy (FA = 0.8). However, a reason of high axial diffusivity needs further investigations.
