Visually evaluate the image using the dental imaging software:
a) Smoothness of the exposed area.
b) Non-exposed area surrounds the whole image
c) High contrast resolution; the distinguishable line pair resolution should be:
• 3.1 LP/mm or better when using 0.8mm Copper filter
• 2.5 LP/mm or better when using 1.8mm Copper filter
d) Low contrast holes must be visible, four holes if using 0.8 mm filter and two
holes if using 1.8 mm filter.
NOTICE!
The line pair resolution depends also on the other factors than the
device itself, for example the imaging Software configurations. According to the
standards, the distinguishable line pair resolution must be 2.5 LP/mm or better.

If the image fails on any of the previously listed criteria, redo the QC program. If it
fails again, recalibrate the device or contact service.
