Abstract: According to the basic principle of ultrasound stimulated vibro-acoustography,an experiment system of vibro-acoustogram has been designed and constructed.The system consists of four parts: high-frequency signal generator,ultrasound emitting and transmitting part,low-frequency signal processing part and computer processing & controlling part.The experimental result indicates that the vibro-acoustogram of rigid body inside the soft tissue or tissue phantom can be obtained by the system.So the system will give some help to the study of vibro-acoustography in tissue.Furthermore,the imaging quality of the system may be improved by using the hydrophone with higher sensitivity and the confocal transducer with better resolution.
