Class hierarchy related to sinogram data. Arrows indicate the parent class. Gray boxes show the new classes added to the library. The classes ProjDataInfoBlocksOnCylindrical and ProjDataInfoBlocksOnCylindricalNoArcCorr store and calculate the sinogram LOR and bin information for the block geometry. The class GeometryBlocksOnCylindrical builds a map of Cartesian coordinates of detectors according to the scanner geometry
