Dynamic ultrasound three-dimensional (3D) imaging using coded transmission is described. 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 the relationship of the system performance to the parameters of the transmitting code such as duration time, repetition period, and total transmission length. A Doppler shift estimation and motion compensated image reconstruction method is described. The computer simulation for the motion compensation image reconstruction was carried out. Ultrasound 3D stroboscopic photography was demonstrated by a preliminary experiment utilizing the evaluation system in a 3D medical diagnostic scanner which has 32 transmitters and 32 receivers.
