Systems and methods are provided for acquiring and reconstructing
projection data using a computed tomography (CT) system having stationary
distributed X-ray sources and detector arrays. In one embodiment, a
non-sequential activation of X-ray source locations on an annular source
is employed to acquire projection data. In another embodiment, a
distributed source is tilted relative to an axis of the scanner to
acquire the projection data. In a further embodiment, a plurality of
X-ray source locations on an annular source are activated such that the
aggregated signals correspond to two or more sets of spatially
interleaved helical scan data.
