Abstract
Relatively large objects are viewed using relatively small area detectors by changing the configurations corresponding to the relative positioning of a source of cone beam imaging energy, the object which is to be viewed, and the area detector. A relatively large area detector is simulated by use of a high quality, high resolution, relatively small area detector. The simulated area detector allows imaging of objects which are too wide and/or too high for an actual area detector. The different configurations may be realized by moving the actual area detector relative to the source or by repositioning the object relative to the area detector. Movement for reconfiguration may be in a plane parallel to a plane in which a scan path is disposed if the object is too wide. If the object is too high, the reconfiguration movement would be perpendicular to a plane in which a scan path, usually circular, is located.
