<p>An ultrasonic diagnostic imaging system is operable to produce tissue Doppler images and data for diagnostic use. The system includes a visual or audible alert which alerts a user to the possibility of aliasing in the tissue Doppler image data and the need to reset the velocity scale of the color map. The visual alert may be a light on the display screen or control panel or contrasting colors to the colors of the color map in an area of the image where aliasing may be occurring. The visual alert may be a histogram displayed in alignment with the color bar of the tissue Doppler image. The indication by the histogram of image values at a velocity limit of the color bar indicates a need to adjust the color velocity scaling.</p> |
