OPTIMIZATION OF EXCITATION WAVEFORM FOR NONLINEAR TRANSMIT-RECEIVE SYSTEMS

摘要

A process for optimizing the excitation waveform that is delivered to a transmitter (103) that, together with a receiver (105), form part of a nonlinear transmission and reception system. The process may include delivering a transmission test signal to the transmitter (201), generating a receive test signal from the receiver that is a nonlinear function of the transmission test signal (203), developing a nonlinear model of the nonlinear function (205), and determining an optimum excitation signal based on the model (207). An application to ultrasonic imaging for breast mammography is also disclosed.
