Based on a recently published theoretical framework, we investigate experimentally, the relationship between phase images and white matter fiber orientation with respect to the orientation of the magnetic field of the MR scanner system. A volunteer was scanned in four different positions with respect to the external magnetic field. Phase information was plotted against the different fiber orientation settings and we found that the obtained correlation reflects at least in parts the proposed theoretical dependency.
