Motionless Laminography X-ray^™ (MLX^®) Concept

Examples

What Are Layer-by-Layer (laminographic) slices?

Ordinary (transmission) radiograph is the "shadow-graph" of features on both sides of the coin.
Using MLX®, the "Head" slice (or layer) is virtually distinct from "Tail" slice

Laminography Technology

What is Motionless CT™?

Digiray® produces its patented Motionless CT™ using

a single x-ray source
using multiple detectors
software that compares the data from each detector

Motionless CT™ allows you to view one layer at a time within the object. This special kind of laminography "peels" away the outer layers of the object, and examines what lies below the surface. By storing each layer separately, RGX® Motionless CT™ can perform computed tomography. Unlike conventional "cat-scans", RGX® Motionless CT™ requires no expensive moving parts.

A single x-ray exposure provides enough information to strip away all obstructing layers and reveal the layer of interest.

Motionless CT™ Examples

pipes and welds [see movie] (265 KB)
circuit board [see movie] (300 KB)
concrete (six inches thick) with reinforcement (133 KB)
aircraft (corrosion, cracks)
human body [see example]
multi-layer circuit boards
disk drives

Motionless CT™ vs. Conventional Computer Tomography (CT)

Motionless CT™ advantages:

While CT relies on multiple repositioning of the x-ray source relative to the object of interest, RGX^®Motionless CT employs no moving parts.
And while CT requires multiple x-ray exposures, you acquire Motionless CT images with a single exposure, dramatically decreasing radiation dosage and increasing throughput.

This technology

determines the gray value of every point in the three-dimensional space of an object
makes it is possible to reconstruct any layer
