APPLICATION STUDY OF BIOMECHANICAL ESTIMATOR USING OPTICAL COHERENCE STRAINGRAPHY TO ATHEROSCLEROSIS

摘要

The authors have developed Optical Coherence Straingra-phy (OCS) as a visualizing technique of tissue strain distribution, by means of deformation of speckle pattern obtained by Optical Coherence Tomography. In this study, ex vivo OCS imaging experiment was carried out using atherosclerotic plaques of WHHL rabbit, compared with simulated results of histologically image-based FEM. Consequently, strain pattern obtained by OCS has qualitative agreement with simulated results. Therefore, it was confirmed that OCS could diagnose biomechanical properties of atherosclerotic plaque tomographically.
