Abstract:
An ultrasound-imaging system, comprising:means for identifying the impulse response of a transmit channel of the ultrasound-imaging system; means for selecting a desired transmit channel signal spectrum, the transmit channel signal spectrum defined by an envelope and a transmit center frequency; means for determining an excitation signal that when applied in the transmit channel produces the selected transmit channel signal spectrum; means for applying the excitation signal; means for receiving a reflected excitation signal centered about a harmonic of the transmit center frequency; means for selecting a desired receive channel filter function to apply to the reflected excitation signal; means for identifying the impulse response of a receive channel of the ultrasound-imaging system; and means for formulating a receive channel filter responsive to the desired filter function and the receive channel impulse response.
