摘要： In ultrasonic imaging, a physically consistent value of blood flow velocity is measured in the vicinity of body tissues. The ultrasound imaging apparatus comprises a shape extraction part for recognizing shape data of biological tissues by using echo signals reflected from a test subject irradiated with ultrasonic waves, a flow velocity distribution acquisition part for detecting blood flow velocities in the vicinity of the tissues from the echo signals, and a velocity determination part for extracting velocity information desired by a tester (objective velocity information). The velocity determination part sets a model of the objective blood flow, and determines a velocity of actually measured velocity distribution consistent with velocity distribution estimated from the model.

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).

摘要： Even when electroacoustic conversion elements with high nonlinearity are employed, a nonlinear imaging is carried out with extracting more nonlinear components. An ultrasonic wave beam is transmitted twice from the transmitter to an identical position on the imaging target, and the signal processor performs computation on the reception signals obtained in every transmission performed twice, thereby extracting a nonlinear component included in the reception signals. In one transmission out of the transmission performed twice, the transmitter delivers the transmission signal to all of multiple electroacoustic conversion elements for driving the electroacoustic conversion elements, and in the other transmission, the transmission signal is delivered selectively only to a part of the multiple electroacoustic conversion elements for driving the electroacoustic conversion elements.

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.
