摘要： There is provided an ultrasonic diagnostic apparatus capable of measuring hardness information of a subject with high time resolution and spatial resolution. The apparatus is provided with a ultrasonic probe 1 and a displacement generation unit 10 configured to displace an inside of a subject and is configured to transmit an ultrasonic beam for displacement detection to a plurality of detection positions of the subject from the ultrasonic probe 1, and to detect a shear wave velocity based on the displacement at the plurality of detection positions in a control unit 3 by using a reflection signal detected in a detection unit 20, thereby outputting hardness information of the subject. The ultrasonic beam for displacement detection is transmitted to one of the plurality of detection positions. A waveform analysis unit 26 of the control unit 3 is configured to perform a change control of analyzing a shear wave resulting from the displacement to thus transmit the ultrasonic beam for displacement detection to another position of the plurality of detection positions. Thereby, it is possible to measure the shear wave velocity with high time resolution and spatial resolution, so that it is possible to obtain the hardness information of the subject with high precision.

摘要： Disclosed is an ultrasound diagnosis device (1) for creating an ultrasound image with a high contrast-to-tissue ratio. Said device sends a transmission pulse to the subject (30), uses an ultrasound probe (20) to receive echoes reflected from an ultrasound contrast agent (32) injected into the subject (30), 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 (30), do not produce sum and difference components in the frequency sensitivity range of the ultrasonic probe (20) as the transmission pulse propagates across the subject (30).

摘要： PROBLEM TO BE SOLVED: To provide a sonar device for detecting or discriminating an object buried in a sedimentary layer on the bottom of the sea efficiently over a wide range with high resolution by transmitting a wide-band and low-frequency sound wave having a wide beam width. SOLUTION: This device is equipped with a parametric transmitter 100, a receiver 200 for receiving the sound wave transmitted from the parametric transmitter, and a synthetic aperture processing part for processing a received signal from the receiver by a synthetic aperture method. A transmission aperture part of the parametric transmitter is formed from a plurality of partial aperture parts, and an adjacent partial aperture part is driven in a reverse phase. In this device, since the synthetic aperture processing is performed by transmitting the low-frequency sound wave having a wide band and a wide beam width, detection of the buried object over a wide range area can be performed highly efficiently, and high resolution can be acquired.

摘要： PROBLEM TO BE SOLVED: To provide a signal processing device with a synthetic aperture sonar capable of accurately imaging an object embedded into a submarine deposit layer.
SOLUTION: Drawing performances, such as the luminance, contrast and position accuracy of the object, in an image after a synthetic aperture processing due to the submarine deposit layer, is improved by providing a time difference between the sound-wave propagation time of the submarine deposit layer and a sound wave propagation time without the submarine deposit layer as a correction of resampling of a sonar receiving signal or a curvature shape in the synthetic aperture processing. Furthermore, embedded objects are drawn accurately, even when there are full swings of ship body, by combining a swing correction means, such as, DPC and MEA with the means.
