    摘要： An ultrasound diagnostic apparatus generates Doppler waveform images whose visibility is improved appropriately in accordance with changes in measurement conditions. The ultrasound diagnostic apparatus includes a frequency-analyzing unit that generates frequency spectrum data on Doppler shift frequency components of ultrasonic waves that are received after being transmitted towards a subject and reflected in the subject, and a line data generating unit for generating line data, wherein arrays of multiple pixels are stipulated according to the corresponding frequencies and each pixel value represents the magnitude of the Doppler shift frequency component, based on the frequency spectrum data. The ultrasound diagnostic apparatus determines whether or not each pixel of line data at a previously appointed time point is a noise pixel, and the values of pixels that are determined to be noise pixels are adjusted by multiplying the pixel value with a weighting factor (w) of 0 to less than 1.

    摘要： An ultrasonic diagnostic imaging system produces audio Doppler from detected Doppler signals. The Doppler signals are detected in a band of frequencies which corresponds to the velocity of blood flow signals, and Doppler information is displayed based on the detected band of frequencies. The audio Doppler system produces Doppler audio in a frequency band which is shifted in pitch from the detected band of frequencies. The operator of the ultrasound system is provided with a user control by which the degree of pitch shifting can be controlled. The ultrasound system displays Doppler blood flow velocities referenced to a transmit Doppler frequency f0, with the audio Doppler being shifted in pitch from the frequencies corresponding to the blood flow velocities.

    摘要： According to one embodiment, there is provided an ultrasonic diagnostic apparatus which comprises data processing circuitry, a display, input interface circuitry and system control circuitry. The data processing circuitry generates at least B-mode data and Doppler spectral data. The display displays images based on the B-mode data and the Doppler spectral data that have been generated by the data processing circuitry. The input interface circuitry inputs one of an instruction to transit to a mode of the Doppler spectral data and an operation to a range gate. The system control circuitry changes a display form of the Doppler spectral data displayed on the display based on the Doppler spectral data generated in a predetermined time after the input in response to the input to the input interface circuitry.

    摘要： An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.
