摘要：

One possible method of ultrasonic diffraction tomography is described. No special transmitter and receiver are required. Only the masks with a narrow slit which attach the transmitter and the receiver are needed to realize a line source and a line receiver, respectively. They are scanned simultaneously to collect data. The theory of the image reconstruction is derived. The feasibility of the method is demonstrated by simulations as well as the experiment.
