Abstract

An X-ray imaging apparatus comprising an X-ray source, a collimator, and an X-ray scatter detector. The X-rays are directed toward an object to be imaged where the collimator and detector are located between the source and object. The X-rays striking the object produce back scattered X-rays which are directed back through the collimator to the detector and an image is produced.
