Abstract: Geometries and configurations are provided for CT systems in which rotational loading is reduced, permitting higher speeds and lighter structures to be implemented in the systems. In certain embodiments a distributed and addressable rotating radiation source is provided with a rotating detector. In other embodiments a distributed and addressable stationary radiation source is provided with a rotating detector. In yet other embodiments a distributed and addressable radiation source is provided that rotates with respect to a stationary detector. The sources may be ring-like, arcuate and/or lines extending at least in the Z-direction. Sources may include a large number of distributed emitters arranged in lines, arcs and one- or two-dimensional arrays.

Abstract: The present invention is an x-ray tube anode with two targets oriented back-to-back. The targets have separate and opposing cathodes. The targets are a fixed distance apart and rotate together on the same bearing shaft. The cathodes are mounted at either end of the vacuum tube. The cathodes may operate simultaneously or independent of each other based on the CT application.
