Abstract
A novel ultrasonic imaging system using impulse ultrasound is described. The properties of transient sound field of a concave transducer were examined in the experiments. Imaging was done based on findings of the transient field using a printed electronic circuit board, DIP type IC as a solid sample and pork meat including muscle and fat as a soft tissue sample. As the results of impulse ultrasound imaging, a spatial resolution of 0.3 mm were revealed and the speckle-free image which differ from the usual pulse imaging can be obtained. Moreover, imaging of the inner parts as well as the surface of the object can be made by adjusting the focal point to a appropriate position.
