3. About Imperium Founded in 1996
Sole provider of ultrasound camera technology
Patented technology
Systems in petrochemical, aerospace, medical fields

4. Why Industry Needs A New NDT Device
Lack of trained NDT personnel
Lack of confidence in thickness readings, missed corrosion
Need higher POD, faster device
Need areas where AUT can’t reach
Advances in imaging technology
A picture is worth 1000 words
Time and cost pressures – Need to do more with less

5. FirstMap Advantages Images are easier to interpret
FirstMap provides an actual image of the defect including thicknesses
Very fast
High resolution
Higher confidence than single thickness readings
Not effected by beam dispersion
Built in delay line
No extensive training required; less trained technician
Real time

Ultrasonic Architecture:
Imperium’s is a sole source provider of a patented ultrasonic-based camera. The design and how the product functions are somewhat similar to a traditional cam recorder.
In the picture above, a cam recorder has an optical architecture based a flash, a set of lenses, and film or more typical today an optical sensor which is based on a technology called Charged Coupled Device (“CCD”).
In the world of ultrasound, the camera has an acoustical flashlight, a set of acoustical lenses, and a proprietary ultrasonic CCD or sensor that captures the sound and displays the image instantaneously.

18. Storage Tank Bottoms
Compare FirstMap’s
easy to interpret readout

19. Microbiological Induced Corrosion
Black areas indicate MIC, note the veins of MIC also

20. Benefits to NDT Industry
Broad application base
Pipelines, storage tanks, pressure vessels
Find smaller amounts of corrosion faster
Does not sacrifice any current data quality
Provide better information to end customer
Better tool to provide comparisons
Use Level 2 thickness inspector to generate images, not just readings
Get to areas where current tools can’t go
Cover more area faster while capturing better data

21. Advanced Corrosion Technologies
“The probability of detection is far superior to standard thickness readings. FirstMap™ is a diagnostic tool that can instantly detect subsurface corrosion down to 1 mm pits. We are now able to quickly and easily identify problem areas that could potentially lead to much bigger issues.”
-Josh Fontenot,
Director of Technologies, ACTT
