• For the DICOM LUM test, enter a value for Maximum allowed.
Then check the scheduled or manual selection box, or both, for test
alerts. The DICOM LUM test is classified a failure if it produces
a value greater than the maximum allowed. Enter a value ranging
from 0 (zero) to 2 (default=1.00). A value of 0 (zero) indicates
perfect conformance with the DICOM Grayscale Standard Display
Function. The DICOM LUM Test assesses the standard deviation of
JNDs (Just Noticeable Differences) per digital interval.
EXAMPLE: Maximum allowed: 1.00 Result: A test result of 0.421
passes, because it is less than 1.00.
Enter the number of measurement you want the system to take for
this test. For the front sensor, the default number of measurements is
15; the minimum,5; the maximum, 32 (All).
If you run the Front Sensor Conformance Wizard with the selection
boxes unchecked for both the DICOM LUM test and the White level
test, you are logging the data from a completed conformance test
without applying the criteria of the DICOM LUM and White Level tests
for Pass/Fail determination.
