|Title:||A method for organic/inorganic differentiation using an x-ray forward/backscatter personnel scanner|
|Published:||September 10, 2013|
|Abstract:||A method is proposed for performing organic/inorganic materials discrimination using an x-ray forward/backscatter scanner. The method is demonstrated using a commercially available personnel security-screening system and requires only image post processing. The method relies upon x-ray interaction physics and the exact registration of forward-and backscattered images, permitting reliable discrimination between low and high atomic number materials over a range of thicknesses. The materials information is used to colorize images and examples of the results are given below.|
