CAROTID ARTERIES ASSESSMENT BY ANALYZING RADIOFREQUENCY COMPONENT OF ULTRASOUND SIGNAL

Penza State University, Penza, Russian Federation

An important problem of contemporary cardiology is diagnosis of cardiovascular diseases at the preclinical stage. The vessels are one of the main target organs affected with cardiovascular diseases. Establishing the arterial wall lesion and its rigidity is essential for the practice of medicine, with which purpose ultrasound investigation is used. Modern technology of radio frequency analysis (echotracking) helps to track the movement of the walls of major arteries. There are two software applications: to measure the thickness of the intima−media complex and to determine vascular stiffness (usually of the carotid arteries). High accuracy, independence from the operator, the ability to monitor reliability of the measurements are important advantages of the new method. Echotracking is also used successfully to determine the effectiveness of the drugs administered. Active introduction of a new noninvasive ultrasound investigation of the common carotid artery with echotracking based on radio−frequency analysis of the movement of the major vessel walls during the passage of the pulse wave will contribute to successful diagnosis and treatment of cardiovascular diseases, reduction of morbidity and mortality.

Key words: echo−tracking, arterial stiffness, carotid arteries, atherosclerosis.
