Abstract: A push wave transmission unit transmits a push wave to a biological tissue of a subject. A tracking wave transmission/reception unit transmits a tracking wave to the biological tissue and receives a reflected ultrasound wave reflected by the biological tissue. An elasticity analysis unit measures a propagation velocity of a shear wave generated in the biological tissue by the push wave and measures an elastic property of the biological tissue based on the propagation velocity, and measures the propagation velocity of the shear wave based on a measurement signal obtained by the reflected ultrasound wave received by the tracking wave transmission/reception unit. A controller determines whether to re-measure the elastic property according to an unnecessary component included in the measurement signal. When determining to re-measure the elastic property, the ultrasound diagnostic apparatus re-measures the elastic property by changing an acoustic property of the push wave according to the unnecessary component.
