Better Than X-Rays: The Z-Backscatter Scan-Van
(click to view full)
American Science and Engineering’s Z Backscatter Van(TM) (ZBV) is a low-cost, extremely maneuverable short-range screening system built into a commercially available delivery van. The ZBV employs AS&E’s patented Z Backscatter technology, which reveals contraband that transmission X-rays miss – such as explosives (including car bombs), plastic weapons, and people – providing photo-like imaging for rapid analysis.
The Z-Backscatter Van is also capable of identifying low levels of radioactivity from both gamma rays and neutrons with optional Radioactive Threat Detection (RTD) technology. This article explains how it works, and provides an illustrative slice of coverage regarding contracts and key events from FY 2005 to the end of FY 2008. The latest set of additions wraps up DID’s coverage…

The Technology

ZBV is a short-range technology, but within that range t’s quite useful. A lot of organic material is low-density, and doesn’t show up well on traditional transmission X-ray images. For instance, organic matter like explosive materials contains low atomic number (low Z) elements such as carbon, oxygen, hydrogen, and nitrogen.
American Science and Engineering, Inc.’s (AS&E) products 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. Akin to light reflection, Z-Backscatter signals are particularly strong whenever the incident X-rays interact with explosives, plastics, and other biological items, which typically contain low Z materials. Even inorganic objects, such as metals, are given shape and form in Z-Backscatter images, making them easier to interpret than transmission images during X-ray evaluation.

The Z-Backscatter vans can scan adjacent vehicles while the system itself is moving, scanning an entire row of parked cars in a single pass-through and producing clear images. They can also be operated in stationary mode by parking the system, and producing X-ray images of vehicles as they pass by. In high-threat areas, a stationary mode van can even be operated remotely by an operator positioned 500 meters/ 0.3 miles away.
The technology’s abilities include near-photo quality views through clothes when used in airport screening systems, which caused something of a privacy uproar. Questions have also been raised re: the health risks to those scanned, which may well be ignored in situations of war or insurrection, but becomes a very live issue when proposed as an requirement for popular activities like airline travel.
In recent years, AS&E has added to their systems’ options with forwardscatter technology. Forwardscatter offers a second scatter perspective that displays dense objects in cargo, such as the shielding found around nuclear materials. An improved Z-Backscatter Van or ZBV Mil trailer in stationary scan mode, for instance, would also have Forwardscatter detectors positioned opposite the X-ray source in the trailer. The Forwardscatter image is displayed simultaneously with the Z Backscatter image, providing the operator with more information about the contents of a scanned vehicle. A vehicle that was also equipped with the radiation threat detection (RTD) option would be able to scan for organic materials, extremely dense shielding materials, and low levels of radioactivity from both gamma rays and neutrons.

The technology, along with manpower, would be the key, he added.”
