Abstract

We present a novel method which provides X-ray CT users the flexibility to reconstruct an object along any of its internal flat features. This internal feature, which is generally not parallel to the object's external surface, can be either an interface between two materials or one surface of an internal layer. This method is developed based on our existing CT differential reconstruction algorithm that is achieved by modifying the popular Feldkamp-Davis-Kress cone-beam reconstruction technique. The theory of this technology is described. One case-study demonstrates that this method is independent of the surface selection of several parallel features. Another case-study shows its capability to reconstruct any individual plate along the plate's own orientation with a three-plate object.
