Compression Elastography and Endoscopic Optical Coherence Tomography for Biomechanical Properties Evaluation of Cerebral Arteries Walls with Aneurysm and Their Phantoms

摘要

A new method for obtaining information about the stress-related properties of the cerebral vessel walls in vivo is described. The method is based on compression elastography and endoscopic optical coherence tomography. A pulse wave is used as a deforming force with a minimal risk of the vessel wall rupture under investigation. Evaluation of the object's deformation is made using test points displacement. New approaches to multilayered tissue like phantoms of blood vessels construction and studies of pulsating flows of biological fluids in them are described. Experimental results of stress-related properties evaluation of the blood vessel walls are presented using tissue like phantoms.
