Comparison of Fiber and Sheet Inclination Angles Estimated Using DTMRI vs Those Estimated by Anatomical Reconstruction

A) Map of primary eigenvector inclination angle obtained from DTMRI for one slice in a fixed rabbit heart.  B) Fiber inclination angle map obtained from the histological reconstruction of Nielsen et al for one section of a dog heart.  C)  Map of tertiary eigenvector inclination angle obtained from DTMRI for the same slice as in A.  D) Map of the inclination angles of the laminae normals obtained from the Nielsen et al reconstruction for the same slice as in B.
