Abstract
Method and device for performing ultrasonic imaging on a region of interest are disclosed. The method comprises: emitting a first ultrasonic pulse and receiving a first ultrasonic echo signal; emitting a second ultrasonic pulse and receiving a second ultrasonic echo signal; emitting a third ultrasonic pulse and receiving a third ultrasonic echo signal; extracting echo signal components from the first ultrasonic echo signal, the second ultrasonic echo signal and the third ultrasonic echo signal; and producing an ultrasonic image of the region of interest according to the echo signal component; wherein, amplitude weighting of the third ultrasonic pulse is equal to the sum of amplitude weightings of the first ultrasonic pulse and the second ultrasonic pulse in magnitude. The method processes and modulates the plurality of ultrasonic echo signals, so as to separate nonlinear components and linear components in the ultrasonic echo signals.
