AUTOMATED EVALUATION OF ARTERIAL STIFFNESS FOR A NON-INVASIVE SCREENING

摘要

This invention relates to medical monitoring and analysis, and more particularly to automated evaluation of arterial stiffness for non-invasive cardiovascular screening. The system tracks and measures motion of carotid artery in the human body using ultrasound based mechanism. Once position of the carotid artery is detected, a wall motion correlation check mechanism is used to measure motion of the artery wall echoes from one frame to another and to ensure that the artery wall motion only is continuously tracked and measured for cardiovascular screening. Further, using values of certain parameters measured during the ultrasound tracking, arterial compliance is measured. Further, from the arterial compliance parameter, arterial stiffness and other associated heart diseases are identified.
