    Abstract: An ultrasonographic technique capable of forming a transmission beam enabling multi-beam transmission/reception of identical transmission sensitivity. An ultrasonographic device for imaging inside of an examinee includes a transmitter for transmitting an ultrasonic pulse signal from an ultrasonic element array to the examinee, and a receiver for receiving the ultrasonic pulse reflected from the examinee. The transmitter transmits an ultrasonic pulse signal having a plurality of peaks of substantially equal transmission intensity in the azimuth direction and a trace in the depth direction of each peak as a substantially straight line, from a transmission opening of the ultrasonic element array to the examinee.

    Abstract: An ultrasound contrast agent composed of at least one kind of low-boiling water-insoluble substance (with a boiling point lower than 37° C.) and at least one kind of high-boiling water-insoluble substance (with a boiling point higher than 37° C.). The former vaporizes to absorb ultrasonic energy upon application of ultrasound, thereby causing the latter to vaporize secondarily, with the resulting bubbles producing an echo image. It is less liable to bumping and hence safe.

    Abstract: In an ultrasonic imaging device having an image synthesizing unit, correlation between images to be synthesized is computed for balancing between an improvement in contrast resolution and an improvement in spatial resolution, and an amount of displacement between the images is computed. When the amount of displacement is large, the signals after envelop detection are synthesized. When the amount of displacement is small, RF signals are synthesized. Alternatively, the mixing frequency may be variable according to the amount of displacement, and the balance between an improvement in spatial resolution and that in contract resolution is achieved according to a degree of the positional displacement.

    Abstract: This invention provides an ultrasonic imaging system that implements imaging by distinguishing sharply and definitely the echo components generated by scattering in a microbubble contrast medium, from the tissue harmonic components generated by nonlinear propagation of a transmitted pulse. This ultrasonic imaging system, constructed to transmit/receive ultrasonic pulses to/from a living body and form a contrast image of the inside of the living body by using the contrast-imaging microbubbles, repeats the transmitting/receiving operations four times in all, under the same transmitting/receiving focus conditions at different phase angles [(a)=0°, (b)=120°, (c)=−120°, (d)=180°] of the carrier of a transmitted pulse wave including a common envelope signal, sums up three time-series receive echo signals associated with (a), (b), (c), forms the contrast image, sums up two time-series receive echo signals associated with (a), (d), forms an image of the living body having a nonlinear pulse propagation property, and makes a superimposed display of the two kinds of images.

    Abstract: An ultrasonograph capable of generating a transmission beam comprising a main beam having a uniform width over a wide range in an ultrasonic wave propagation direction by one-time transmission of an ultrasonic pulse. A weighted mean value of a plurality of transmission delay time values corresponding to focal lengths of transmission pulse waves having a plurality of focal points which are set in the ultrasonic wave propagation direction is calculated for each of elements constituting a transmission aperture and used as the delay time. The curvature of a transmitted wave front is close to a short focal length in the center portion of the transmit aperture and is close to a long focal length in the peripheral portion. Thus, a transmission beam including a relatively narrow main beam with a uniform width over a wide range in the ultrasonic wave propagation direction can be generated.
