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： 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： 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.
