Abstract
Methods for contrast-enhanced ultrasound imaging that implement coded multi-pulses in each of two or more different transmission events are described. Data acquired in response to the two different transmission events are decoded and combined. In some embodiments, the coded multi-pulses include two or more consecutive Hadamard encoded ultrasound pulses. In other embodiments, multiplane wave pulses can be used. Such multiplane wave pulses can be coded using Hadamard encoding, as one example. In addition, the multiplane wave pulses can be further coded using amplitude modulation, pulse inversion, or pulse inversion amplitude modulation techniques.
