Abstract
Some embodiments include a support movable with at least four degrees of freedom, a therapeutic radiation source coupled to the support, a plurality of radiation sources disposed in a fixed relationship to each other, the plurality of radiation sources movable in the fixed relationship with at least four degrees of freedom, a detector to acquire a projection image based on radiation emitted from one of the plurality of radiation sources, and a processor to perform digital tomosynthesis on the projection image acquired by the detector and a plurality of other projection images to generate a cross-sectional image representing a plane viewed from a perspective of the therapeutic radiation source.
