X-ray Bomb Detection Using Dual Energy X-ray Imaging
X-ray bomb detection has undergone a revolution since the development of Dual Energy X-ray imaging. Dual Energy is a digital radiology imaging algorithm that enables the capture of multiple X-ray images of an item, while differentiating between organic and inorganic materials. Compatible with airport security standards, the Orange hue in the X-ray image implies organic materials, while a Green shade indicates soft inorganic materials (such as glass). Blue is the color used for "hard" inorganic (metallic) substances. Due to the fact that explosive devices are organic, organic/inorganic detection is vital when trying to locate improvised explosive devices. As most drugs are also organic, the same principle applies to contraband.
A pioneer in the field, Vidisco was the first company to introduce X-ray bomb detection using Dual Energy capabilities in portable digital radiology systems in 2004. The Vidisco revolutionary XR-DE Plus module is an improved 2011 version of the XR-DE module that was first launched in 2008, allowing the Vidisco proprietary algorithm to differentiate between organic and inorganic substances when using a Pulsed X-ray source (Golden Engineering′s XR150/XR-200/XRS-3). The device, which snaps onto the nose of the Golden X-ray source, does not reduce standard X-ray penetration.
