Abstract
Methods and apparatus for an imaging system are provided. The imaging system includes a gantry having a stationary member coupled to a rotating member. The rotating member has an opened area proximate an axis about which the rotating member rotates. An x-ray source provided on the rotating member. An x-ray detector may be disposed on the rotating member and configured to receive x-rays from the x-ray source. A rotary transformer having circumferentially disposed primary and secondary windings may form part of a contactless power transfer system that rotates the rotatable portion of the gantry at very high speeds, the primary winding being disposed on the stationary member and the secondary winding being disposed on the rotating member.
