Z Backscatter X-Ray

Z Backscatter technology captures the data from the X-rays that are scattered away from the object, back towards a near-sided detector. This primary scattering effect is known as “Compton Scattering.” The Z Backscatter image is bright white where X-rays scatter the strongest, indicating organic matter, such as explosive material and drugs. Even inorganic objects, such as metals, are given shape and form in Z Backscatter images.

We create photo-like Z Backscatter images showing organic materials by directing a sweeping beam of X-rays at the object under examination, and then measuring and plotting the intensity of scattered X-rays as a function of the beam position. This is made possible by patented “Flying Spot” technology. Flying Spot technology allows the position of the X-ray beam to be defined at every instant, so any Z Backscatter signal received is easily correlated with the precise region of the object undergoing inspection.

Z Backscatter's photo-like images are easy-to-interpret, revealing both the presence and exact position of organic components of the inspected object. This significantly enhances the ability of operators to quickly understand and interpret scan results.
