摘要： An objective is to enable calculation of a distribution of a physical property such as a density inside a measurement object, even when the distribution of the physical property value is non-uniform, within a feasible period of time without causing image deterioration due to phenomena such as refraction and multiple-reflections caused by the non-uniformity. To this end, the physical property value that makes an evaluation quantity be an extremum is outputted, where the evaluation quantity is a liner sum or a product of exponential function of: an equation residual quantity that is a residual being a difference between an operator term and an external force term of an equation of motion; a non-uniformity detection equation residual quantity that is a residual of an equation of detecting the non-uniformity of the physical property value from a matching degree of solutions of the equation of motion under two types of boundary conditions; and a conditional equation residual quantity that is a residual of a constraint condition.

摘要： An ultrasonic imaging device which narrows the width of annular areas to be established, without increasing the number of channels. The controller establishes the annular areas 421 to 42p the number of which is larger than the number of signal lines, along line intersections between wave surfaces 51 to 54 of reflective waves and a multi-dimensional surface of the probe 1. The controller selects multiple annular areas (0, 0), (0, 1), and (0, 2) with focal depths differing, for example, by an integral multiple of the ultrasonic wavelength λ, out of the multiple annular areas being established, and connects the multiple transducer elements positioned within the selected multiple annular areas with an identical signal line. Accordingly, the received signals from the selected multiple annular areas arrive at multiple time points shifted by the time corresponding to the wavelength, and the signals do not cancel one another out.

摘要： An ultrasound imaging apparatus includes a transmitter which transmits an ultrasound pulse to a subject, a receiver which receives ultrasound coming from the subject, and a signal processor to process a received signal at the receiver and generate image data. The receiver has a predetermined reception band, and the ultrasound pulse transmitted by the transmitter has one frequency band with a frequency peak. Each of an upper limit frequency and a lower limit frequency of the one frequency band is set to be values which make a low frequency harmonic component and a high frequency harmonic component produced by the ultrasound pulse be within the reception band. The signal processor generates image data by using a nonlinear component of at least one of the low frequency and high frequency harmonic component received by the receiver.

摘要： The present invention provides an ultrasonic imaging device which narrows the width of annular areas to be established, without increasing the number of channels, thereby enabling enhancement of a focused sound pressure. The controller establishes the annular areas 421 to 42p the number of which is larger than the number of signal lines, along the line intersections between the wave surfaces 51 to 54 of reflective waves and a two-dimensional surface of the probe 1. The controller selects multiple annular areas (0, 0), (0, 1), and (0, 2) with focal depths differing by an integral multiple of the ultrasonic wavelength λ, out of the multiple annular areas being established, and connects the transducer elements positioned within the selected multiple annular areas with an identical signal line. Accordingly, the received signals from the selected multiple annular areas arrive at multiple time points shifted by the time corresponding to the wavelength, and the signals do not cancel one another out. Furthermore, the annular areas the number of which is larger than the number of signal lines can be established, thereby narrowing the width of the annular areas.

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.
