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 a Cauchy data set of measured cone beam data to a processor. The processor extrapolates by use of John's equation 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.
