Analysis of Screen Defects
The visual inspection of screen defects is to determine if artifacts
observed during system inspection can be attributed to the Dome
display. Conduct the visual inspection during system acceptance, at
least annually, and when necessary to isolate artifacts.
To inspect the display screen for defects
Follow these steps to inspect the display screen for defects.
• With the displays off or in the dark state, view for scratches and
gouges. Record on the form those that are not admissible for
mammography reading.
• With displays turned on, prepare the displays for the inspection of
dots and debris. You can do this by using the Windows Desktop
popup menu.
• Place the cursor anywhere on the desktop. Right-click to open
the popup menu and select Properties. Record the existing
background selected for later reference.
• Select None for background setting and select the color Black from
the pull-down color palette. Click OK. All screens should present
Black.
