摘要： An ultrasonic probe in which two-dimensional array transducer elements are arrayed convexly both in one direction of the two-dimensional array and in the direction perpendicular to the former direction relative to the direction where an ultrasonic wave is transmitted. By switching a transducer element selecting switch circuit provided near the transducer elements, the shape of the diameter of the probe for transmitting and receiving of ultrasound and the position of the diameter are arbitrarily determined. An ultrasonic diagnostic apparatus in which a fresnel ring is formed as an diameter by a control signal to a transducer element selecting switch circuit, the number of cables for connection between the probe and the main body is decreased by bundling the transducer elements in one ring and effecting the connection, the fresnel ring is moved every ultrasonic transmission/reception cycle by the control signal to the transducer element selection switching circuit, and an object is three-dimensionally scanned with an ultrasonic beam.

摘要： An ultrasound signal processor has a receiving signal digitizing circuit, waveform conversion circuit for mixing a produced digital signal by a reference signal, a cumulation circuit for performing a cumulation processing of a series of converted signals, a delay circuit subject to the cumulation processing, and a circuit for adding delayed signals, whereby the frequency of the receiving signal is shifted to a lower frequency and thereafter subjected to a cumulation processing which perform over-sampling technique so that the accuracy of an analog to digital conversion can be improved drastically. The ultrasound signal processor further has a circuit for converting a receiving signal into a low frequency signal by analog-mixing and a circuit for passing a low frequency component of the analog-converted signal, whereby a higher frequency receiving signal can be digitized even if the digitizing circuit has a insufficient sampling rate.

摘要： A needle-like ultrasonic probe includes an inner needle received in a hollow, tubular outer needle for rotation about an axis thereof. The inner needle has a pointed distal end, and a notch is formed in an outer peripheral surface of that portion of the inner needle which is located adjacent to the distal end thereof. At least one ultrasonic transducer, as well as an acoustic lens for converging an ultrasonic wave, produced by the ultrasonic transducer, onto a point near to the outer peripheral surface of the inner needle, is provided in the notch. A filler, having an outer surface conforming to the outer peripheral surface of the inner needle, is fitted in the notch. With this construction, after the inner needle is smoothly stuck into a living tissue, even if it is rotated and axially moved, the living tissue is less affected or damaged by the inner needle.
