摘要： In spectral Doppler imaging, a high PRF is used independent of the velocity scale. The adjustment is then of the velocity scale. By optimizing the velocity scale independent of the high PRF in an on-going or automated basis, user activation may be avoided and/or interruption to reconfigure for an altered PRF may be avoided. The acquired data may be stored, allowing for past data to be processed again when a new velocity scale or other setting is selected. The resulting spectral Doppler image may continue to display spectra over time without a gap or without premature loss of spectra due to reconfiguring.

摘要： If the boundary value of a velocity scale set in a case where the information indicating the velocity of the moving body is displayed on a liquid crystal panel is less than a threshold value, the frequency of pulses used in pulse-width control is set to 20 kHz in such a manner that noise ascribable to the pulses for pulse-width control will not be displayed on the liquid crystal panel. If the boundary value of the velocity scale is equal to or greater than the threshold value, then the frequency of pulses used in pulse-width control is set to 200 Hz in such a manner that noise ascribable to the pulses for pulse-width control will reside at a position remote from the information indicative of velocity.

摘要： During transmission, a speed of ultrasound pulses gradually reduces due to their energy loss from acoustic impedance. A thickness and a density of piezoelectric (PZT) elements and a sound speed in the PZT elements decides energy of the ultrasound pulses and their detecting depth. A speed of moving objects and an angle of the moving objects with the ultrasound pulses may change a speed of reflected ultrasound pulses and affect their time of flight (TOF) and TOF shift. A method of Coding ultrasound pulses combines advantages of a continuous wave ultrasound and a pulsed wave ultrasound. So, it can be used to obtained the TOF and the TOF shift and calculate the depth and the moving speed of the detecting objects, which also avoids a problem of an aliasing for highly moving speed of the objects.

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.
