A Real-Time High-Resolution Ultrasonic Arterial Imaging System
Atherosclerosis is one of the major diseases affecting the health of people throughout the world. Detection of atherosclerotic lesions by invasive techniques presents serious hazards to patients, while current noninvasive techniques often do not yield accurate diagnosis. There is an urgent need for instrumentation that will provide safe, noninvasive, and accurate diagnosis of this disease. Since July 1973, the Mayo Foundation and Stanford Research Institute have been involved in a joint effort to develop high-resolution ultrasonic imaging techniques for clinical application to the diagnosis of human cardiovascular diseases. A first generation, real-time ultrasonic arterial imaging system for the simultaneous visualization of vessel anatomy and blood flow in the carotid and femoral arteries has been developed at SRI for clinical evaluation at the Mayo Foundation. This instrument incorporates both B-scan and Doppler measurement modalities.
