This invention uses the cone beam CT (Computer Tomography) principle to obtain nondestructive image of any object. For good reconstruction datasets from 2 orthogonal planes about the object are required in order to augment the signal relative to the polar artifacts of a standard Feldkamp reconstruction...http://www.google.com/patents/US7170966?utm_source=gb-gplus-sharePatent US7170966 - Practical implementation of a CT cone beam algorithm for 3-D image reconstruction as applied to nondestructive inspection of baggage, live laboratory animal and any solid materials
