In an approach to X-ray inspection image display systems, a colorized X-ray inspection image is received comprising a monochrome X-ray inspection image that is colorized in accordance with an X-ray inspection system false colorization scheme. The colorized X-ray inspection image is filtered by performing pixel shading on the colorized X-ray inspection image to generate a custom colorized X-ray inspection image having a custom false colorization scheme that is different from the X-ray inspection system false colorization scheme.

The present disclosure provides a radiation inspection apparatus and a radiation inspection method. The radiation inspection apparatus includes: a radiation inspection device comprising a ray source and a detector that cooperates with the ray source to perform scanning inspection on an object to be inspected, the radiation inspection device having an inspection channel for the object to be inspected to pass through when scanning inspection is performed thereon; and traveling wheels provided at the bottom of the radiation inspection device to enable the radiation inspection apparatus to travel in an extension direction of the inspection channel, and the traveling wheels are configured to rotate 90° to enable the radiation inspection apparatus to travel in a direction perpendicular to the extension direction of the inspection channel.
