AAPM TG18 Test Service

NOTE: This service is available only for Dome Ex, Dome GX4MP, and Dome Sx displays.

The AAPM TG18 Test service helps you perform various evaluations recommended by

the American Association of Physicists in Medicine, Task Group 18. To help you complete

a test suite (set of evaluations), the TG18 Test runs a wizard that describes the basic steps

you must complete for each evaluation in the test. When an evaluation requires a subjective

evaluation of a test pattern, the wizard explains the criteria for satisfactory display

performance.

You need a photometer to take luminance measurements on Dome Ex, Dome GX4MP, and

Dome Sx displays. The TG18 Test supports these photometers:

• Wellhofer LXplus

• Minolta LS-100

WARNING: Completion of a TG18 Test frequently requires preparing the display and the

environment in accordance with applicable sections of the TG18 document. The wizard used

for each evaluation provides only an outline of the basic test steps. It does not describe all

prerequisite conditions and information required to perform the evaluation. Refer to

Dome CXtra User’s Guide for details.

You can change the evaluations included in any test. During setup, identify the photometer

to use and define the evaluations you want to complete for the acceptance test, plus the

daily, monthly/quarterly, and annual tests. After running the acceptance test, use the other

tests to monitor image quality on each display.
