    Abstract: A computed-tomography apparatus that includes a CT scanner including an X-ray source and a detector covering respective angle ranges in the axial and transaxial planes of the CT scanner. The CT detector includes first detector elements disposed on a first surface to capture incident X-ray photons emitted from the X-ray source, and second detector elements sparsely disposed on a second surface different from the first surface, the second surface being farther away from the scanner than the first surface, the second detector elements being smaller in number than the first detector elements. Each of the second detector elements is reachable only by X-ray photons originating in a small angle range around a line connecting the X-ray source and a center of the surface of the detector element, the small angle range being determined by the predetermined distance separating the first and second surfaces and a size of the detector element.

    Abstract: An illustrative embodiment provides a computer-implemented process for semantic verification of multidimensional data sources that receives a trusted output from a trusted multidimensional expression engine, receives an un-trusted output from an un-trusted data source and determines whether a query produces a correct semantic result, wherein the correct semantic result is within a predetermined tolerance. Responsive to a determination that the query does not produce a semantically correct result, identifies queries having semantically incorrect results to form a local subset, notifies a query planner of semantically incorrect queries and determines whether to process queries locally. Responsive to a determination to not process queries locally, creates a set of simplified multidimensional expression queries for remote execution.
