The tractography of myofibers in three dimensions. Our quantification and tractography algorithms enable the reconstruction of fiber structure in myocardium tissues. Results are compared with OCT image in (a) ventricular septum of Heart I (Media 1 ^{(3.3MB, MP4)} ) (b) left atrium of Heart II (Media 2 ^{(3MB, MP4)} ) (c) left ventricle of Heart III (Media 3 ^{(2.3MB, MP4)} ) in a volume of 2 mm × 2mm × 1mm underneath the surface. The fiber structures are also shown along with fiber OCT image in en face plane. The reconstructed fibers match the streamline in original OCT data in (d) ventricular septum (Media 4 ^{(2.5MB, MP4)} ) (e) left atrium (Media 5 ^{(2MB, MP4)} ) (f) left ventricle (Media 6 ^{(1.6MB, MP4)} ).
