Patent ID: 8218726

Claim:
An imaging tomography apparatus comprising: a non-mobile, stationary frame having a central opening therein; a rotor mounted in said central opening of said non-mobile, stationary frame for rotation around a central axis proceeding through said opening; a plurality of power-consuming components mounted on said rotor, said plurality of components being configured to generate tomographic data and including an x-ray source and a radiation detector, said plurality of components being operable in a standby mode in which said plurality of components consume a first amount of power and in an operating mode wherein said plurality of components consume a second amount of power that is substantially higher than said first amount of power; a slip ring assembly located between said rotor and said non-mobile, stationary frame; said stationary frame comprising a power supply path configured to supply power from a power source located externally of said non-mobile stationary frame to said slip ring assembly; said slip ring assembly comprising dimensions and electrical properties that permit said slip ring assembly to supply power to said plurality of components that does not substantially exceed said first power level; and an energy storage mounted on said rotor and connected to supply power at least to said x-ray source during said operating mode.
