Exam of a Pythagoras Cup

A three-dimensional radiographic exam of a modern Chinese Pythagoras cup was taken to reveal the simple structure of the cup that allows the siphoning mechanism to occur. The original Pythagoras cup was designed around 500 BC to teach its users to drink in moderation. If liquid is filled into the cup above a specific height, it all completely funnels out of a hole in the bottom of the cup and onto the drinker’s lap.

Revealing the Past: Blackbeard's Queen Anne's Revenge

Working with the N.C. Department of Cultural Resources, the Digitome non-destructive x-ray imaging system is being used by Davidson College to exam encrusted relics from Blackbeard’s infamous pirate ship, the Queen Anne’s Revenge. The relics lay lost on the ocean floor off the N.C. coast for almost 300 years.

Unveiling the Hollow Interior and Measurements of a Geode

Since geodes have closed surfaces, the only practical ways to view the inner crystals are to break them or to use a form of imaging that makes use of light outside of the visible range like x-radiography. A Digitome volumetric exam is able to detect the contour of the void within the rock and identify areas of particularly low or high thicknesses in a non-destructive manner.

Exam of an Alaska Quarter

A Digitome exam was taken of an Alaska quarter to see if the two separate faces could be isolated, and it was successful. One distinct layer of the coin scan reveals the grizzly bear springing out of a rushing river and biting his catch—a salmon. Moving down through the coin, the face of George Washington is clear, but analysis of the words reveals that the radiographic image face is actually a mirror image of the real face!

Calculating the Measurements of Objects

Digitome is capable of accurate measurement down to the order of microns given a small focal spot size and low pixel depth for a digital image plate, typical conditions for high-resolution digital radiographs. This video demonstrates how Digitome measures objects in an exam; the objects used have well-known sizes to test the software’s accuracy.

How it Works

Digitome Volumetric Technology is built on patented view reconstruction from several images (typically 8-16) acquired from a plurality of angles—a two-axis regime. Various exam configurations are possible through careful application of geometric accuracy principles. Views are reconstructed directly from the exam images and are presented near real-time for analysis.
