Multi-tube imaging system reconstruction

A tomographic apparatus includes at least two x-ray sources that rotate about and alternately emit radiation into an imaging region. The at least two x-ray sources emit radiation from a first set of angular positions during a first data acquisition cycle and from a different set of angular positions during a subsequent data acquisition cycle. At least two sets of detectors detect primary radiation emitted by a corresponding one of the at least two x-ray sources and produce data representative of the detected radiation. An interleaver interleaves the data associated with the first and the subsequent data acquisition cycles for each of the at least two x-ray sources.
