An Osage Orange As A Diffusion Imaging Phantom For The Evaluation Of Slice-Accelerated Diffusion Imaging Sequence

The evaluation of sequence and its parameters for the diffusion tensor imaging is difficult because of the physiology noise and the lack of a proper diffusion phantom. Available phantoms are structured to provide the proton signal outside the tube, which is opposite to the neuronal fiber. The magnetic susceptibility of the tubes in the phantom induces a directional variation of the MR signal. Osage orange is a fruit with columns running from the center core to the surface. Each column was found to provide anisotropic diffusion. Therefore, it was used as a diffusion phantom to evaluate the slice-accelerated diffusion sequence.
