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.

摘要： There is provided an ultrasonic wave diagnosis instrument. The ultrasonic wave Doppler diagnosis instrument transmits an ultrasonic continuous wave in a range direction and receives a reflective wave of the ultrasonic continuous wave. The ultrasonic wave Doppler diagnosis instrument includes: a modulation unit that subjects the ultrasonic continuous wave to frequency modulation such that a phase is varied in accordance with the distance of the range direction; a demodulation unit that demodulates the reflective wave for each range of the range direction while interlocking with the frequency modulation, and generates a reception signal in the range in a separated state; and a presentation unit that presents information by using a signal of a Doppler component based on the reception signal.

摘要： A three-dimensional ultrasonic diagnostic apparatus has a cross-sectional image generating unit, a region-of-interest setting unit, a three-dimensional image generating unit and a display unit. The cross-sectional image generating unit generates a cross-sectional image corresponding to a desired cross-sectional plane by performing a two-dimensionally scan on the cross-sectional plane within a three-dimensional scannable region. The region-of-interest setting unit sets a second region of interest for a three dimensional image within a three-dimensional region based upon a first region of interest in the cross-sectional image. The three-dimensional image generating unit performs a three-dimensionally scan on the three-dimensional region including the second region of interest, sets a view point based upon the second region of interest, and generates the three dimensional image, including the second region of interest, in a line of sight from the view point. The display unit displays the three-dimensional image.

摘要： An ultrasonic probe has a plurality of modules joined at least along the elevation direction. The module has a plurality of first piezoelectric transducers having a first width with respect to the elevation direction. The module has at least one second piezoelectric transducer having a second width narrower than the first width with respect to the elevation direction. The second piezoelectric transducer is arranged at the module ends with respect to the elevation direction. The module is arranged in such a manner that the second piezoelectric transducer faces the second piezoelectric transducer of the adjacent module.
