METHOD OF AND SYSTEM FOR OBTAINING LINEAR DATA FOR OBJECT SCANNED USING NON-COLLIMATED, POLY-ENERGETIC X-RAYS

摘要

According to one embodiment, a system for linearizing image data corresponding to one or more objects and output by an imaging device is provided. The system includes a processor configured for: receiving the image data from the imaging device; and producing a generally linear relationship between the image data and a thickness of the one or more objects. The generally linear relationship is produced according to the equation; $$ I=I_o{}^{-\frac{\mu }{\sqrt{l}}l}.$$ ;I is an intensity of the image data, I₀ is an intensity of energy produced by the imaging device for outputting the image data, μ is an attenuation coefficient of the one or more objects, and l is the thickness of the one or more objects.
