"3-D" Density Plot (density mapped as
height) shows rivet (red) and sealant (green).
See the next picture to learn how RGX® imaging can distinguish a slit in
the sealant (bright green line protruding from rivet) from a crack.

Horizontal line crosses rivet (white hexagon),
then a slit in the sealant (black). The vertical intensity profile (on the right) shows
that in spite of the density dip caused by the slit in the sealant, the total density is
greater than that of the metal thickness. The RGX® system enables the customer to
avoid false positives. The customer gains Return on Investment (ROI) by reducing
unnecessary dissassembly and repair work.

A subtle black horizontal line reveals a crack
extending from one rivet hole to another. Crack propagation such as this led to the roof
ripping open in the Aloha Airlines aircraft.
NOTE: This feature is easier to see in the original high resolution image (before
conversion to a format for the World Wide Web).

The portable system meets or exceeds the
military specification for 2% image resolution and contrast discernment. The
electronic chip package is next to the resolution standard (aluminum penetrameter) to show
scale. (The letters "AL" for "ALuminum" appear backwards in the
radiographic "negative" that shows opacity as white, and lack of density as
black.)
