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 algorithm. Here, we suggest a practical way of
implementing the 2 orthogonal planes theory by replacing the 2 gantry
rotations by 2 rotations of only one fixed gantry and one movement of the
object position, making it simple and low cost. This method is applied to
the non-intrusive inspection of baggage or imaging of mice for
pharmaceutical purposes where the object has to remain in a horizontal
plane throughout the procedure. This algorithm can also be applied to
nondestructive testing of any solid materials, for example: imperfections
in semi-conductors, electronic components, composite materials etc.
