ABSTRACT:
Blood flow measurements are obtained by determining changes in time varying textural patterns of reflected ultrasonic waves from the blood flow at a predetermined position in a blood vessel. Electrical signals generated in response to reflected ultrasonic waves from moving blood cells are autocorrelated to indicate changes in the textural patterns.
