Abstract:
1. A method of transducer excitation in a medical ultrasound imaging system having a waveform generator and a transducer, the method comprising the steps of: (a) generating by the waveform generator an excitation waveform signal with three base waveforms (A, B, C), each of which is a unipolar pulses, wherein the waveform signal represents a gated, stepped approximation of a Gaussian envelope multiplied by a cosine carrier signal, with said three base waveforms satisfying the relationships of: voltage-time product of positive (A+B)=negative C, where C comprises two pulses having the same duration; t (b) selecting a carrier frequency signal, F (c) applying the excitation waveform signal to the transducer.
