Summary:Based on the pulse-coded transmitting and wide-band receiving system, this paper describes A research of phase inversion technique to extract high-frequency ultrasonic tissue harmonic information by making use of wide-band ultrasonic transducer on frequency of 20 MHz, 35 MHz and 50 MHz. The results indicate that adopting the method in this paper is with better fundamental frequency inhibition and at the same time can increase the amplitude of second harmonic information effectively. This method is superior to that traditoncal one by using RF filter to extract tissue harmonic information.
