Abstract
A relatively simple, flexible, and economical system is reported for processing biological signals which contain frequencies in the audio range. The microprocessor-based system has been tested successfully on ultrasonic scattered signals from blood and urine to provide diagnostic information in real-time. Measurements were obtained for average velocity, standard deviation of velocity (indicative of laminar and turbulent flow), relative flow rate, and relative cross-sectional area as functions of time. Comparison of these measures at various locations along a vessel, and at various times in the life of a patient, could help to detect stenotic zones and physiological changes associated with disease.Keywords
