An apparatus for performing computed tomography having a radiation source and at least one radiation detector spaced from the radiation source and which generates an output signal representative of the strength of the received radiation from the radiation source. A part support for holding a plurality of parts is positioned in between the radiation source and the detectors. The part support is rotatably mounted about an axis generally perpendicular to a vector between the radiation source and the detectors so that, upon rotation of the part support, the radiation detectors generate an output signal corresponding to the internal structure of parts supported on the part support. A computer system receives the output signals from the detectors and, under program control, generates a report of the internal structure of the parts on the part support.
