Adding a Modality and Configuring Modality Image Quality
Performing a Contrast
Test
There are three types of contrast test that can be run.
• Standard - this test prints all TFTs from within the selected TFT Set.
IMPORTANT: The Custom and Broad sample tests use the TFT Set and
Contrast Table selected by you as a starting point. They
print in the middle of a sheet with nine images. The other
eight images on the test may use image processing from
any TFT Set/Contrast Table.
• Custom - this test prints images whose image processing is close to
the starting point.
• Broad sample - this test prints images whose image processing
varies more broadly from the starting point.
IMPORTANT: A contrast test always uses the last image sent by the
modality. You must disable printing before you send the
image you want to use for the contrast test.
