    摘要: In an ultrasound diagnosis apparatus, two reception data in two scan directions formed between ultrasound transmision and reception directions can be acquired upon simultaneous reception. The reception data are acquired by sequentially shifting the transmission direction. When the reception data in a predetermined scan direction is obtained, Doppler shift amounts are calculated upon acquisition of a predetermined number of reception data in the predetermined direction. In this case, ultrasound transmission and reception operations are so controlled as to acquire the Doppler shift amounts in each direction every predetermined time interval.

    摘要: A Doppler sensitivity measuring unit measures the Doppler sensitivity of Doppler spectrum data obtained by ultrasonic wave transmission/reception with respect to a predetermined region of an object to be examined. A spectrum shape model generating unit generates a spectrum shape model on the basis of a window function used when the above Doppler spectrum data is generated. A threshold setting unit sets a threshold range in which trace waveform data displaces by a predetermined amount in the frequency axis direction on the basis of the spectrum shape model and the Doppler sensitivity, and sets a predetermined number of thresholds at almost equal intervals in the threshold range. A trace data generating unit selects a threshold for the acquisition of desired trace waveform data by generating trace waveform data while sequentially updating the plurality of set thresholds.

    摘要: An ultrasonic blood flow imaging apparatus of this invention includes an ultrasonic probe, a transmission system, a reception system, a B mode processing system, a CFM processing system, an FFT processing system, a video system, and a control system. The CFM processing system includes a new discriminating means. The discriminating means receives power, average blood flow velocity, and variance data output from an auto-correlation circuit. The discriminating means can discriminate Doppler shift signals (blood flow signals), noise signals, and clutter signals from each other with high precision on the basis of a relationship in combination of two or more received factors, i.e., the power, average blood flow velocity, and variance data. With such discrimination processing, only necessary blood flow signals can be extracted, and hence high-precision blood flow information can be obtained.
