Evaluating DVM Test
Patterns After you have printed one of the DVM test patterns, follow these steps to
access the print quality:
1. Place the film on a light box with the viewing conditions you typically
use.
2. Check for artifacts that could either mimic or obscure clinical
information. The absence of such artifacts indicates that image quality
is acceptable for mammography.
3. If you see an artifact, reprint the image.
a. If the same artifact appears in a consistent location, the imager may
be malfunctioning. Call an authorized service provider of Kodak
products.
b.If the artifact does not repeat in the same location, the cause is
probably a film defect. Switching to a different film cartridge,
preferably from a different film lot, should eliminate the problem.
Automatic Image Quality
Control (AIQC) The built-in densitometer is a key component in the patented Automatic
Image Quality Control (AIQC) process. The AIQC feature allows the laser
imager to automatically monitor and adjust image quality parameters to
ensure optimum image quality.
The laser imager adjusts the parameters each time the laser imager prints a
calibration film to ensure image consistency from film-to-film and lot-to-
lot. A calibration film is printed whenever:
• AIQC detects that a new film lot number has been loaded.
• You request a calibration test from the local panel.
• A calibration has not been performed on a film cartridge for 7 days.
Operating in Manual Mode Under normal conditions, AIQC is running to maintain consistent image-
quality parameters. If errors occur, such as calibration failure, you can
operate in manual mode until the error is corrected.
