    摘要: An ultrasonic diagnostic imaging system produces a spectral Doppler display on which a parameter such as peak or mean velocity is automatically traced. If the user is dissatisfied with the automatically drawn trace (30), the user can manipulate a cursor (88) on the display screen to grab a point (82, 86) on the trace and drag the trace to a new location relative to the spectral display or manually redraw a portion of the trace. In an illustrated embodiment the spectral Doppler trace (80) includes defined key timing points in the heart cycle which can be adjusted by the user in both the velocity and time dimensions of the display. Graphically displayed values and calculations of the display are automatically updated in response to adjustment of the trace.)

    摘要: An ultrasonic diagnostic imaging system produces a spectral Doppler display on which automated measurements may be made. The waveform is analyzed by the ultrasound system to identify the peak velocity of each cardiac cycle of the sequence, and the cardiac cycle with the highest peak velocity value. When a measurement tool is launched, the system displays the highest peak velocity cycle and makes the selected measurement on the data of that heart cycle. The system may advantageously use a peak velocity tracing algorithm in support of this feature. The technique can be used with a variety of measurement tools.
