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 Dual Energy capabilities in portable digital radiology systems in 2004. The Vidisco revolutionary XR-DE module was first launched in 2008, allowing the Vidisco proprietary algorithm to differentiate between organic and inorganic substances when using a Pulsed X-ray source. The device, which snaps onto the nose of the Golden X-ray source, does not reduce standard X-ray penetration.
