Abstract

Imaging Mueller polarimetry (IMP) was used in reflection geometry and large field of view configuration for the in-plane visualization of brain fiber tracts by exploring the anisotropy of the refractive index of healthy brain white matter. Our initial studies demonstrated that IMP successfully detects in-plane orientation of fiber tracts on a flat surface of the excised brain specimens. This work, performed ex-vivo on complete fresh calf brains proves the potential of IMP as a technique suitable to detect both presence and orientation of brain fiber tracts in the adverse conditions of complex surface topography and presence of blood.
