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： 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 a radiation-pressure elastography technique for transmitting a ultrasound focused beam into a test object body and diagnosing the hardness thereof, it is required to consider high sensitivity and safety.In the present invention, the focused beam is transmitted to two positions as a means for displacing a tissue and exciting a shear wave. In addition, time control is performed in such a manner that a transmit beam serves as a burst-chirp signal, and ultrasound waves are transmitted and received while sweeping a transmit frequency. On this occasion, when the distance between the two focused points and the transmit frequency become integral multiple of the wavelength, two waves interfere with each other, thereby obtaining a large amplitude. Furthermore, when the transmit frequency becomes equal to a resonance frequency peculiar to the tissue, the amplitude also becomes larger. Accordingly, a small intensity of transmit waveform enhances sensitivity. In addition, transmission using the burst-chirp signal facilitates widening of a bandwidth of the transmit frequency, enabling usage of a frequency highly sensitive for a target measurement site. Optional number of focused points and arbitrary positions thereof allow a wide area to be covered.

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).
