Non-Invasive Optical Imaging for Measuring Pulse and Arterial Elasticity in the Brain

摘要

An optical imaging system and a method for generating a report regarding elasticity of arteries in the brain of a subject under test. Light output from the light source of the imaging system non-invasively illuminates at least one blood vessel or region of interest in the brain and, upon the interaction with the vessel, is registered with an optical detector to obtain a shape parameter of a hemodynamic pulse in the vessel. The shape parameter is further correlated to an elasticity parameter of the blood vessel(s) feeding the brain region of interest and presented in a form of report that may be a two- or a three-dimensional image of the parameter across the tested region of the brain.
