Abstract
An ultrasound imaging apparatus includes a transmitter which transmits an ultrasound pulse to a subject, a receiver which receives ultrasound coming from the subject, and a signal processor to process a received signal at the receiver and generate image data. The receiver has a predetermined reception band, and the ultrasound pulse transmitted by the transmitter has one frequency band with a frequency peak. Each of an upper limit frequency and a lower limit frequency of the one frequency band is set to be values which make a low frequency harmonic component and a high frequency harmonic component produced by the ultrasound pulse be within the reception band. The signal processor generates image data by using a nonlinear component of at least one of the low frequency and high frequency harmonic component received by the receiver.
