Abstract
An inspection system using penetrating radiation wherein pixels corresponding to transmitted radiation which has been attenuated to at least a predetermined level are displayed in a first color. Pixels which correspond to radiation which has been backscattered to a least predetermined level are displayed in a second color, and pixels which correspond to the remainder of the transmitted radiation are displayed in a third color. Additionally, the brightness of the color of each pixel is controlled in dependence on how far above or below the predetermined level the detected transmitted or scattered signal is.
