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： In an ultrasound signal processor, respective received signals received at received signal processing units are sampled by a sampling clock of a frequency which is sufficiently higher than a Nyquist sampling frequency of an upper limit of a frequency band width for each of the received signals received at the received signal processing units so as to be digitized. Each of the digitized received signals is multiplied by a reference signal of a predetermined frequency to produce converted received signals in which the frequency of the digital received signal waveform is shifted, and converted signals are cumulated for a time which is longer than the sampling period. Each of the cumulated signals is processed by a clock frequency lower than the sampling clock in connection with an ultrasound beam in one direction, so that after one transmission operation of ultrasound, a plurality of ultrasound received beams are formed from the received signals received at the respective transducers.

摘要： An ultrasonic flow mapping apparatus transmits and reflects waves from sampling points on a two-dimensional cross-section. The waves are detected while transmitting repeatedly ultrasonic pulses. The phase shifts of different reflected waves are calculated, and displayed in color to show a distribution of blood flow velocity. Artifact due to reflected waves from body organs, which remain even by using MTI filters, is detected from phase signals, which have not passed through the MTI filters, and the artifact is removed by lowering display brightness for a sampling point corresponding to a relevant detection output.

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.

摘要： An ultrasonic diagnostic apparatus in which the distortion of the received wave signal due to the ununiformity of the interior of an human body can be reduced accurately with a small circuit scale and an ultrasonic image of high resolution can be produced. The apparatus comprises a probe including an arrangement of elements for transmitting and receiving ultrasonic pulses to and from the interior of a subject, delay means for delaying the wave signal received from each element of the probe, and a plurality of adder means connected in series to the output of the delay means for adding the output signal of the preceding stages thereby to form an ultrasonic beam. The apparatus further comprises correlation means for calculating the correlation of two or more output signals of any of the adder means, and delay correcting means for estimating as many delay correction amounts as the input signals to the delay means from the time difference between adjacent signals generated from the correlation means thereby to correct the delay time of the received wave signal.

摘要： An ultrasonic diagnostic apparatus transmits an ultrasonic beam into an object to be examined using a multi-ring arrangement formed with transducer elements arrayed two-dimensionally in concentric rings and receives an echo so as to create a tomogram or a three-dimensional image of the object. To correct for focusing error due to the difference in length of ultrasound propagating paths, the ultrasonic diagnostic apparatus groups the transducer elements so as to form a multi-ring arrangement, transmits/receives ultrasonic beams with a delay to each ring of the multi-ring arrangement and scans the ultrasonic beam so as to create an ultrasonic image, measures delay error due to presence of a sound speed non-uniformity portion of the object and changes either the coupling of the multi-ring or the delay time based on the measurement error.
