Abstract
A source applies imaging energy that passes through an object being imaged and is then detected by a detector. A scanning trajectory causes the detector to provide measured cone beam data to a processor. The measured cone beam data is over a characteristic surface with a corresponding characteristic problem. The processor solves the characteristic problem such that missing cone beam data is determined. The measured cone beam data and the determined cone beam data together provide a complete data set for exact image reconstruction.
