ABSTRACT:
Stereoscopic radiography apparatus includes a source of two beams of radiation, collimators so as to convert the beams into generally fan shaped beams, radiation detectors for converting the radiation passing through an object being examined into an electrical signal containing image information. The radiation detector may have at least one scintillator to convert radiation which has passed through an object into light, and at least one self-scanning array of photodiodes to convert the light into an electrical signal containing image information. Fiber optic coupling may be provided between the scintillator and the self-scanning array of photodiodes. The first image information resulting from the first beam and second image information resulting from a second beam are created substantially simultaneously. Apparatus for receiving the signal to store, process or display the image may be provided along with a visual display system. In one embodiment the two radiation beams are emitted simultaneously and in another embodiment they are emitted sequentially. A uniquely configurated fiber optic coupling member may be employed. The method of effecting such stereoscopic radiographic imaging.
