摘要： Method and apparatus for ultrasonic blood flow velocity measurement based upon the doppler principle (doppler measurement), combined with simultaneous echo amplitude imaging by employing ultrasonic pulses (echo imaging). The method is used for investigation of living biological structures, in particular during movement, for example a heart function. The main application will be in hospitals and the like. The doppler measurement and the echo imaging is effected sequentially with so short intervals that the echo imaging is updated with a sufficiently high rate for obtaining an acceptable picture quality, with the doppler measurement occupying a substantial portion of the time. The information is presented in real time on a display screen. A control unit synchronizes the doppler measurement and the echo imaging, and there is incorporated one or more transducers in the equipment. The doppler measurement is interrupted during intervals which constitute a not unimportant portion of the time, for carrying out a complete or a partly sweeping of the ultrasonic beam over the image field. There is formed an estimate of the doppler signal and the estimate replaces the directly measured doppler signal either all the time or during portions of the time, for example during the interruption interval.

摘要： A method for correcting ultrasound data includes acquiring ultrasound data using an ultrasound probe having a plurality of transducer elements associated with a plurality of channels that include conductive pathways and communicating the ultrasound data as received ultrasound signals along the conductive pathways of the channels. The method further includes determining a crosstalk signal that is generated in one or more of the channels by at least one of communication of the received ultrasound signals along the channels or vibration of one or more of the transducer elements. In one aspect, the method also includes modifying one or more subsequently acquired ultrasound signals that are communicated along the channels based on the crosstalk signal.

摘要： A method and apparatus for acquiring multi-line acquisition ultrasound data. Ultrasound signals are transmitted into an area of interest. Echo signals are acquired and analyzed to produce a first data stream associated with a first receive beam. The first data stream is decimated by removing at least two consecutive data samples therefrom, while passing at least two consecutive data samples to form a first decimated data stream. Using this decimation pattern, a bandwidth of one-half to three-quarters of the data sampling rate after decimation may be achieved.

摘要： Method and apparatus for synthesizing a continuous estimate signal of a Gaussian signal resulting from ultrasonic Doppler measurement on a fluid flow, from existing segments of the Gaussian signal. The segment signals are first stored and there is at the same time calculated a characteristic frequency parameter for each segment. The frequency parameter is combined with the first stored segment signal for transposition thereof to a base-band at or about the zero frequency point, and this base-band signal is used to generate coefficients in a controlled filter device which on the basis of a broad-band input signal gives a synthesized filter output signal which is a substantially Gaussian signal. The filter output signal is multiplied by a weighting or window function for smoothing the transitions between successive segments. Parallel to the above signal processing there is for each segment of the initial Gaussian signal on the basis of said frequency parameter, formed a parameter at each instant which is an estimate of the frequency parameter of the initial signal between the segments, in order to thereby represent the comparatively quick variations in the location of the frequency spectrum of the initial signal. The latter estimated frequency parameter is combined with the smoothed filter output signal so that this is transposed back to the frequency range of the initial signal and thereby constitutes the synthesized continuous estimate signal. The invention primarily is intended for use with ultrasonic blood flow measurement in living biological structures. This method and apparatus may be incorporated into a complete system for investigating circulatory systems, particularly in hospitals.
