Claim 0:
1. 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 plurality of emitters including a first set of emitters configured to operate at a first voltage and a second set of emitters configured to operate at a second voltage, different than the first voltage; and
a source controller for triggering the first set of emitters for acquiring first projection data by the one or more detector arrays and triggering the second set of emitters 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 set of emitters and the second set of emitters are positioned in an alternating fashion.
