Traditional transmission X-Ray images like medical X-Rays result when X-Rays pass through an object to a detector located on the far side of the object. The resulting image is bright where most of the X-Rays pass through the object and dark where most X-Rays are absorbed.

Rapiscan® Systems 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.

THE DIFFERENCE WITH Z BACKSCATTER

Rapiscan® Systems creates 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.
