Below the left wing
- Digiray's Reverse Geometry X-ray® (RGX®) tube is under the wing.
- An array of eight (8) detectors is above the wing.
- No longer is it necessary to
--have the human worker drill out each of the many
thousands of rivet holes
--stress the aircraft structure by drilling
--wait for eddy current or film inspection

Above the left wing
- An array of eight (8) detectors is above the wing.
- Digiray's Reverse Geometry X-ray® (RGX®) tube is under the wing.
- The eight detectors gather information from eight different angles simultaneously. The inspector finds critical cracks much more quickly than with eight
separate film exposures.
- The personal computer analyzes the rich data from all eight detectors using Digiray's
Motionless CT™ laminography software. The inspector can locate
and measure crack depth.
- X-ray dosage is that of conventional system. Mechanics 50-100 feet
away can work on other parts of the plane.
