Patent ID: 7933378

Claim:
A computed tomography system, comprising: a first and a second x-ray tube, disposed at different z-axis locations at about a same angular position around an examination region, that both emit, alternatively, radiation beams, during an axial scan, that traverse an axis of rotation within the examination region; wherein the first x-ray tube emits a first radiation beam having a first outer projection that traverses a plane perpendicular to the axis of rotation, and the second x-ray tube emits a second radiation beam having a first outer projection that traverses a plane perpendicular to the axis of rotation, wherein the first outer projections define a width of a volume within which the emitted radiation beams are substantially bound; a common detector that detects radiation from the x-ray beams that traverses the volume and generates data indicative thereof; and a reconstructor that reconstructs the data to generate volumetric image data of the volume.
