Abstract
Provided is a technique that implements harmonic imaging in an ultrasound diagnostic apparatus, being unaffected by the voltage-dependent distortion and nonlinear characteristics of the transmit system in the ultrasound diagnostic apparatus that incorporates the transmit amplifier, the ultrasound probe, and the like, facilitating adjustment of the transmit voltage, and achieving a frame rate substantially equivalent to that of the conventional PI method. In the amplitude modulation method that synthesizes the transmit acoustic fields, thereby eliminating a basic wave component of an acoustic wave and creating an image from nonlinear component echoes being extracted, one transmit and receive out of plural transmits and receptions to obtain one scanning line also serves as the transmit and receive for obtaining other scanning line. The echo signals obtained by the shared transmit and receive are used to form the receive beams respectively on both the scanning lines that share the transmit and receive.
