On September 13, 2016 , the USPTO issued U.S. Patent Number 9,442,082 to RAPISCAN SYSTEMS, INC., which was successfully prosecuted by Novel IP.

The '082 patent  is directed towards  an X-ray system for processing X-ray data to determine an identity of an object under inspection. The X-ray system includes an X-ray source for transmitting X-rays, where the X-rays have a range of energies, through the object, a detector array for detecting the transmitted X-rays, where each detector outputs a signal proportional to an amount of energy deposited at the detector by a detected X-ray, and at least one processor that reconstructs an image from the signal, where each pixel within the image represents an associated mass attenuation coefficient of the object under inspection at a specific point in space and for a specific energy level, fits each of pixel to a function to determine the mass attenuation coefficient of the object under inspection at the point in space; and uses the function to determine the identity of the object under inspection.

Independent Claim 1 describes " An X-ray system for processing X-ray data to determine an identity of an object under inspection, comprising: an X-ray source for transmitting a plurality of X-rays, wherein said X-rays have a range of energies, through the object; and a detector array for detecting said transmitted X-rays, wherein said detector array comprises a first set of detectors and a second set of detectors, wherein each of said first set of detectors comprise scintillator material and a filter configured relative to the scintillator material such that the transmitted X-rays pass through the filter before passing through the scintillator material, wherein each of said second set of detectors comprise scintillator material and do not comprise a filter, and wherein 1% to 4% of the detector array comprises the first set of detectors and wherein 99% to 96% of the detector array comprises the second set of detectors.
