ABSTRACT:
An industrial CT system is provided for three dimensional imaginig which includes a three dimensional cone beam of hard radiation fixed with respect to a two dimensional scintillation detector array. The object is positioned on a turntable interposed between the radition source and detector array. Data from two dimensional views are stored as the object is rotated on the turntable about a fixed axis. The data is sufficient upon completion of one revolution to construct a transparent three dimensional image of the object. A positioning encoding arrangement adjusts for variations in the object's mass density to optimize scan-compute times while enhancing image resolution.
