Abstract
A computed tomography (CT) imaging system is disclosed. The CT imaging system may be used in a multi-modality imaging context or other context. In one embodiment, the CT imaging system provides for both fast rotation of the rotating X-ray source and detection components and low dose of X-rays generated by the source providing several clinical and economic benefits such as low dose and sufficient image quality and no or insignificant investment in room shielding associated with diagnostic CT dose.
