Abstract:
1. An imaging system comprising: a radiation source configured to project radiation from a first focal spot onto an object; a plurality of radiation detectors disposed around at least a portion of the object, wherein the plurality of radiation detectors measure received radiation along a path projected from the first focal spot to the plurality of detectors; an imaging region from which the detectors provide image information for image reconstruction; and a plurality of collimators positioned between the object and the plurality of radiation detectors, wherein at least one collimator at a first end of the plurality of collimators and at least one collimator at a second end of the plurality of collimators are aligned to a second focal spot different than the first focal spot and having a different location, wherein the collimators at the first end and the second end of the plurality of collimators are physically skewed by a fixed angle in opposite directions that is defocused from the first focal spot.
