Abstract
In one example embodiment, a method of volumetric image reconstruction of an examination region includes directing x-rays from an anode of an x-ray device towards the examination region from multiple positions relative to the examination region, including multiple focal spot positions radially shifted relative to the anode. X-rays that have passed through the examination region are detected and first multiple x-ray attenuation values are determined for each of the multiple positions. The first multiple x-ray values are based at least in part on the detected x-rays. Second multiple x-ray attenuation values associated with multiple levels are determined. The second multiple attenuation values are based at least in part on the first multiple attenuation values and the multiple positions. The method further includes generating a volumetric image reconstruction of the examination region based at least in part on the second multiple x-ray attenuation values.
