Abstract :
Dynamic ultrasound 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 velocity estimation and motion compensated image reconstruction method.
