This patent describes a computerized tomographic industrial radiation system for constructing a three dimensional transparent image of at least a portion of an object. It includes a point source generator for generating a non-pulsed, three dimensional cone beam of emitted rays of hard radiation; collimator means associated with the point source generator for controlling the three dimensional cone beam angle and the peripheral configuration of the three dimensional cone beam; positioning means for locating the object in the path of the three dimensional cone beam such that a predetermined volumetric portion of the object is exposed to the three dimensional cone beam of hard radiation for attenuation of the radiation passing through the object; two dimensional detector means fixed with respect to the point source generator and located on the opposite side of the object from the point source generator for recording the attenuated radiation and converting the attenuated radiation through the scintillation screen into a two dimensional shadow image.
