Claim 11:
12. A stationary computed tomography (CT) system, comprising:
one or more detector arrays extending around at least a portion of an imaging volume;
a stationary distributed x-ray source unit, the x-ray source unit comprising a first plurality of emitters configured to be triggered at a first voltage and second plurality of emitters configured to be triggered at a second voltage, different than the first voltage; and
a source controller for triggering the first and second plurality of emitters at the first voltage for acquiring first projection data by the one or more detector arrays and at the second voltage for acquiring second projection data by the one or more detector arrays, the first projection data and the second projection data usable to reconstruct one or more basis material composition images or monochromatic images of an object within the imaging volume,
wherein the first plurality of emitters and the second plurality of emitters are positioned in an alternating fashion.
