PROBLEM TO BE SOLVED: To image a CHI component only without executing processing for discriminating a THI component and a CHI component in a reception signal of an ultrasonic wave.SOLUTION: In an ultrasonic image diagnostic apparatus, a transmission part generates a driving signal so that both a frequency component S12 of a low frequency harmonic wave and a frequency component S13 of a secondary harmonic wave generated by non-linear propagation property of a tissue when a transmission ultrasonic wave propagates through the tissue of a subject are out of an imaging frequency band S2, a reception part receives an ultrasonic wave reflected in the subject and acquires a reception signal, and an image generation part generates a CHI image as an ultrasonic image based on the reception signal.SELECTED DRAWING: Figure 4 |
