ADJUSTABLE TRACING OF FLOW VELOCITIES IN DOPPLER VELOCITY SPECTRA
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. )
