7 Monitor Adjustments - Optional (As Required)

Procedure

  1. Set up the monitor contrast and brightness using the SMPTE Pattern.
    1. If you are not on the Service Desktop, click the SERVICE DESKTOP icon.
    2. Click the IMAGE QUALITY icon.
    3. Select INSTALL SMPTE IMAGE. (Approximately 3-4 minutes.)
  2. Display the SMPTE pattern. Use the browser to select Exam 1000, which contains the SMPTE pattern, and enlarge the image to full screen display.
  3. Increase the Contrast to maximum. Adjust monitor contrast until the anatomical structure (window width) appears at the expected window levels.
  4. Increase the Brightness to maximum. Adjust the monitor brightness the anatomical structure (window width) appears at the expected window levels.
  5. Decrease the Brightness, until the raster just fades into, and matches, the monitor screen background. At this point, the 5% and 95% patches should be just visible.

    If additional tweaking is required to attempt to match the monitor image to the filmed image, use only the brightness control.

    If the CRT image exhibits any tearing or smearing of the alphanumeric characters, then reduce the contrast setting slightly until the tearing/smearing is just eliminated. The optimum setting for contrast is the highest setting that does not cause tearing/smearing of the alphanumeric characters.

    You should always finish up by displaying and filming images of anatomy (typical heads and bodies), and asking the technologist to compare the CRT image to the film image.

  6. To view SMPTE on text monitor, swap the video cable.
