Abstract

Provided herein are Pulse-Inversion (PI) sequences that provide for fundamental frequency suppression in nonlinear imaging applications. In an embodiment, a weighting scheme is applied to the received echo pulses resulting from transmit pulses of alternating polarity to reduce the effect of transducer motion. In an embodiment, a three-pulse weighting scheme is applied to a PI sequence. In other embodiments, different combinations of the three-pulse weighting scheme are applied to a PI sequence.
