摘要： Disclosed is an ultrasound diagnosis device for creating an ultrasound image with a high contrast-to-tissue ratio. Said device sends a transmission pulse to the subject, uses an ultrasound probe to receive echoes reflected from an ultrasound contrast agent injected into the subject, and forms an image. The transmission pulse is sent such that nonlinear interactions between the constituent frequency components of said transmission pulse, as a result of the acoustic nonlinearity of the subject, do not produce sum and difference components in the frequency sensitivity range of the ultrasonic probe as the transmission pulse propagates across the subject.

摘要： When multiple tissues having differing speeds of sound are intermixed in the viewing field of a measured subject such as a living body, the invention measures hardness, such as modulus of elasticity or viscosity, with high precision. As a means for detecting heterogeneity of sound speed in the tissues of a subject, a displacement-generating transmission beam is applied from a displacement generating beam-generating device (13) of a displacement-generating unit (10) on an ultrasound probe (1) to irradiate a focused ultrasonic wave into the living tissue and generate a shear wave. From the displacement-time waveforms of multiple positions of the shear wave detected using the displacement detection transmission beam-generating device (22) and the displacement detection received beam-computing device (23) of a displacement-detecting unit (20), at least two pieces of information, such as the integrated value and the maximum amplitude value, are obtained. On the basis of the two pieces of information, a heterogeneity-detecting device (26) of the displacement-detecting unit (20) detects the physical magnitude associated with the heterogeneity in sound speed arising from the tissue structure and displays same on a display (5).
