Abstract
The method of the present invention combines an ensemble of truncated partial cone beam projections to synthesize a complete virtual projection. The individual partial projections are obtained with CT scanners, where for each partial projection the investigated object is positioned at precise locations specified by formulas described in the present application (e.g., formulas (3), (4), (6) and (18) for linear cone beam synthetic scanner arrays or formulas (9)-(13), (20), (21) and (25)-(27) for circular cone beam synthetic scanner arrays). Prior to the actual reconstruction, the partial cone beam projections are combined to form a complete virtual projection, equivalent to a projection one would obtain by using a sufficiently large detector.
