Abstract

Computerized axial tomography is employed with respect to large relatively dense objects such as a solid fuel rocket engine. High energy X-rays, such as a 15 MeV source is used. To develop clean images, a collimator is employed with a relatively minute acceptance angle. Acceptance angles on the order to 1°, and in a preferred embodiment 7 minutes of a degree, are used. In a preferred embodiment, the collimator may be located between the object and the detector, although in other embodiments, a pre-collimator may also be used, that is between the X-ray source and the object being illuminated.
