摘要
The present invention relates to a material classification method using dual energy X-rays and a calibration phantom apparatus and system for performing the method, and more particularly, to a transmission image obtained through a cylindrical or elliptical columnar calibration phantom rotating in a cargo screening machine. It relates to a method of correcting a material fractionation coefficient by generating a plurality of attenuation-based basis for the reference, a method for classifying a material using the corrected material fractionation coefficient, and a calibration phantom apparatus and system for performing the method.
