[Potentials of ultrasonic methods for assessing the hemodynamic characteristics of the cardiocerebrovascular system]

This paper reviews ultrasonic methods used at present to evaluate hemodynamic parameters of different organs and velocity characteristics of circulating blood. The ultrasonic methods make it possible not only to diagnose different vascular lesions but also to investigate the effects of unusual environmental parameters on the human body. The paper give a classification of the existing and advanced procedures based on ultrasonic location when applied to determine hemodynamic characteristics of the cardiocerebrovascular system. The paper presents a description of ultrasonic methods used in studying the heart (velocity characteristics of the circulation of cardioelements), brain (pulse oscillations of vessel blood filling in the cranial cavity), and large arteries (blood filling and blood flow velocity.
