Abstract:
A fuzzy tracking method of binary-state image for ultrasonic temp measurement includes emitting ultrasonic pulses from the probe of ultrasonic temp measurer to tissue of human body, receiving the ultrasonic echo, binary processing to each echo frame to obtain its binary-state image, using track window for navigation track to the image to obtain the accumulated time shift, curve fitting, and differentiation to obtain local time shift. Its advantages are high precision and less calculations.
