Abstract
Multi-mode ultrasonic images are formed by processing the ultrasonic echoes from a single transmit pulse in parallel to display both tissue and motion. In a preferred embodiment short transmit bursts are employed to produce echo ensembles for tissue motion imaging. At least one sequence of echoes of the ensemble is also B mode processed for display of tissue structure. Preferably both the B mode and motion processing are performed in parallel. A substantially constant pulse repetition frequency reduces artifact development when imaging in the two modes from the same transmit pulse.
