The present invention is to provide a cerebrovascular analyzer which enables to early diagnose various cerebrovascular refractory diseases as well as a cerebral thrombosis by analyzing the cerebrovascular system biodynamically on the basis of the basic data such as an electrocardiogram signal, a phonocardiogram signal, a plethysmogram signal, and an ultrasonic Doppler signal to obtain the biodynamic property and the blood flow property of the cerebrovascular blood vessel branches and by calculating the elastic coefficient, the compliance, the resistance, and the blood flow volume of each blood vessel branch in cerebrovascular system.

La présente invention concerne un système d'analyse cérébrovasculaire permettant un diagnostic précoce de diverses maladies cérébrovasculaires incurables, telles que la thrombose cérébrale, par mesure d'un coefficient élastique, de la souplesse des vaisseaux sanguins, de la résistance du flux sanguin et du flux sanguin dans chaque ramification cérébrovasculaire. La mesure est réalisée par analyse biomécanique des vaisseaux sanguins dans le cerveau au moyen d'un électrocardiogramme, d'un phonocardiogramme, d'un électro-encéphalogramme, d'une onde d'impulsion et d'un signal de doppler à ultrasons en tant que données de base afin de mesurer des propriétés biomécaniques et des propriétés de flux sanguins des vaisseaux sanguins dans le cerveau en vue du diagnostic de maladies cérébrovasculaires.
