A METHOD AND SYSTEM FOR VISUALIZATION OF CARDIOVASCULAR PULSATION WAVES

摘要

A method for visualization of cardiovascular pulsation waves. A living body is illuminated with light penetrating through a skin of the body for interacting via absorption and/or scattering with a vascular system of the living body. Light reflected from the living body is collected in a focused frame into an image capturing device. A series of frames is captured by the image capturing unit. The frames of the series of frames are multiplied by a reference function synchronized with a periodical physiological process of the body. A correlation image is formed by summarizing respective pixels over the frames of the series of frames to the reference function. An output image representing dynamics of blood-pulsation waves in the living body is calculated from the correlation images as function of the phase of the periodical physiological process of the body. Also a system for application of the method.
