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 54.6-cm (21.5-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.
