Test Patterns
Two sets of test patterns are available for testing the image quality of the system,
peripheral devices, review stations, or a PACS.
• The original set of test patterns (labeled Test Patterns) includes images
intended for a variety of tests. Unlike the TG-18 test patterns, however,
these test patterns are not tied to a unified standard.
• The newest set of test patterns was created by the American Association
of Physicists in Medicine Task Group 18 (TG-18). The TG-18 test patterns
on the system were adapted for the 1024 x 768 pixel image area of the
51-cm (20-in) system monitor. For information on using these test patterns,
read IEC publication 61223-3-6 (62B/588/CD).
Transferring the Test Patterns
The test patterns are stored on a separate part of the system hard drive. You
must transfer the test patterns to a different part of the hard drive before you
can view them. The transferred test patterns remain unless you delete them.
