Abstract
A medical diagnostic ultrasound imaging method fires a sequence of pulses into a body and then receives, beamforms, weights and sums the resulting echo signals to suppress first order echoes. The sequence of pulses includes at least two pulses that differ in amplitude and phase. In one form, no two pulses of the sequence have the same amplitude and opposite phase. In another form, only linear echoes are suppressed. In a third form, second and third order echoes are preserved while linear echoes are suppressed.
