Abstract
In the stereo radiographic system, an electronic x-ray image detector is exposed, through a three dimensional object to be viewed, with x-rays successively from two points separated by a preselected angle. The respective signals generated by the x-ray image detector during the successive exposures are digitized and stored. A video display is driven to generate, on successive frames, alternating images based on respective ones of the stored signals and the eyes of a user viewing the display are alternately occluded in synchronism with the alternation of the images thereby to provide to the user a stereoscopic densitometric view of the three dimensional object.
