An experimental ultrasonic three-dimensional (3D) imaging system for high-speed data acquisition has been developed. A sequence of 3D images of moving objects is reconstructed for each transmission of pulses modulated by Walsh functions. Then, the dynamic structure of the objects is extracted from the image sequence. In this paper, we discuss a motion-compensated image reconstruction method for improving the quality of the image sequence. The computer simulation for the motion compensation image reconstruction was carried out. In the experiment of dynamic imaging using the developed system, an improvement in contrast was obtained by the motion compensation with the Doppler shift detection method.
