摘要: The development of systems physiology is hampered by the limited ability to relate tissue structure and function in intact organs vivo or vitro. Here, we show application a bimodal biopho- tonic imaging approach that employs optical coherence tomography fluorescent investigate structure-function relation- ship at level heart. Reconstruction cardiac excita- tion was depth penetration 2m min atrial tissue, 1m ventricular myo- cardium. subcellular resolution clearly demonstrated microscopic fiber orientation governs pattern wave propagation functionally characterized rabbit si- noatrial atrioventricular nodal preparations revealed struc- tural heterogeneities contributing arrhythmias. combination this biophotonic with his- tology and/or immunohistochemistry can span multiple scales res- olution for investigation molecular structural determi- nants physiology. © 2008 Society Photo-Optical Instrumentation
