| Abstract: | The thrombus formation is a serious complication in the development of artificial heart,so it is of great importance to detect the thrombus efficiently within the artificial heart.It is feasible to adopt the method of Ultrasonic Doppler for thrombus detection.This paper elaborates the principle,approaches of the thrombus detection system using Ultrasonic Doppler,including designing of the ultrasonic probe,Transmitter/Receive circuit,data processing and col-lecting system,and then through careful analysis of the thrombus signals by short-time Fourier analysis（STFT）,the mimicking thrombus is detected. |
