1. A portable radiography scanning system, comprising:
a radiation detector configured to generate digital radiography images based on incident radiation;
a radiation emitter configured to output the radiation;
a first sensor configured to determine a first distance between the radiation detector and the radiation emitter; and
a computing device configured to:
receive the digital radiography images from the radiation detector;
compensate one or more of the digital radiography images for variations in magnification of the digital radiography images;
determine, for one or more of the digital radiography images, a second distance between the radiation emitter and an interface between the radiation and an object being scanned to generate the digital radiography images;
determine magnification correction factors for the one or more of the digital radiography images based on the first distance and the second distance; and
generate one or more compensated radiography images based on the magnification compensation by compensating the one or more of the digital radiography images based on the magnification correction factors, the compensated radiography images being associated with physical location information.
