Claim One:
1. A method comprising: emitting a respective imaging x-ray from each of a plurality of imaging x-ray sources disposed in a fixed relation with respect to one another in a closed curve configuration; acquiring x-ray absorption projections of an object, each of the x-ray absorption projections associated with an imaging x-ray emitted by a respective one of the plurality of imaging x-ray sources; performing digital tomosynthesis using the x-ray absorption projections to generate a cross-sectional image of the object; and delivering a therapeutic x-ray from a therapeutic radiation source to the object, wherein each of the plurality of imaging x-ray sources is disposed in a fixed relation with respect to the therapeutic radiation source, and wherein the plurality of imaging x-ray sources comprise carbon nanotube field-emission electron sources.
