摘要： PROBLEM TO BE SOLVED: To achieve the compatibility between a dynamic focus receiving and an encoded transmitting/receiving technology by an inexpensive circuit constitution. SOLUTION: A wave-receiving aperture is divided into small apertures, and a wave-receiving beam former 36 is divided into wave-receiving subbeam-formers 36a to 36n in a manner to correspond to the small apertures. Then, a phasing- adding process is performed once, and then, a process wherein encoded signals are compressed in the time axial direction is performed at encoder/decoders 37a to 37n. In the end, output signals for a plurality of the encoder/decoders each are phase-add-processed again by a second beam former 38. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus capable of forming transmission beams having main beams of a uniform width extending to a wide range in an ultrasonic propagation direction by the once transmission of an ultrasonic pulse. SOLUTION: Concerning transmission pulse waves respectively forming wave transmission focal points which are set plurally in the ultrasonic propagation direction, the weighting average of a plurality of wave transmission delay times corresponding to respective focal distances is obtained by each element constituting a wave transmission diameter and actual wave transmission is performed with it as a delay time. As a weight in the case of obtaining the average of delay times, a wave transmission effective diameter width corresponding to each wave transmission focal distance is selected and a weight in the direction of a wave transmission diameter for realizing it is calculated. Next, this is used in the direction of the focal distance. The curvature of a wave front to be transmitted is close to the wave front of a short focal distance at the center of wave transmission diameter as a result, and close to the wave front of a long focal distance at a peripheral part, thereby the wave front of a non-spherical surface is formed. Thereby, the transmission beams having the relatively thin main beams of the uniform width extending to the wide range in the ultrasonic propagation direction can be formed by the once transmission of the ultrasonic pulse.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonographic apparatus improved with imaging speed. SOLUTION: Ultrasonic beams are encoded using an expanded Barker code to realize the ultrasonographic apparatus capable of simultaneously transmitting and receiving a plurality of ultrasonic beams.

The plurality of ultrasonic beams can be simultaneously transmitted and received without deteriorating the S/N ratio, so that the image pickup speed per image can be increased remarkably. As a result, it is possible to realize the ultrasonographic apparatus capable of performing real time imaging for an object.

摘要： PROBLEM TO BE SOLVED: To receive ultrasonic beams in plural directions simultaneously by transmitting ultrasonic beams at a time in an ultrasonic diagnostic apparatus for obtaining the ultrasonic image of a part to be examined in real time by forming ultrasonic beams at two-dimensionally arranged vibrators and scanning the part to be examined. SOLUTION: This diagnostic apparatus has a probe 10 with plural vibrators 19 arranged two-dimensionally for transmitting/receiving ultrasonic waves. The aperture for ultrasonic transmission/receiving is formed with multiple rings consisting of the two-dimensionally arranged vibration bundled concentrically, applying the delay to the gap between each ring of the multiple rings to transmit/receive ultrasonic beams, moving the aperture, so that an ultrasonic image is formed. In this case, the probe 10 has plural apertures 20a, 20b for transmitting/receiving ultrasonic waves formed in the multiple rings, and can receive beams in plural directions simultaneously by transmitting ultrasonic beams from these apertures at a time. Therefore, the frame rate of the ultrasonic image to be obtained can be improved with the improved real-time response.
