    摘要： In accordance with one embodiment, a contactless power transfer system is provided that comprises a stationary member including a power input configured to receive power at first voltage from a power supply. The system further includes a rotating member rotatably coupled to the stationary member and a rotary transformer. The rotary transformer has primary and secondary sides, with the primary side being disposed on the stationary member. The primary side has a primary winding that receives power at the first voltage from the power input. The secondary side is disposed on the rotating member and produces power at a second voltage. The secondary side has a rotating core and separate secondary sub-windings, each of which has forward and return paths that are circumferentially disposed about the rotating core. The forward and return paths of each of the sub-windings rotate proximate to, and are disposed a substantially equal distance from, the primary winding disposed on the stationary member.

    摘要： A multichannel, contactless power transfer system includes a primary power inverter disposed on a stationary side of the system, and an auxiliary power inverter disposed on the stationary side of the system. A rotary transformer has a primary side thereof disposed on the stationary side of the system and a secondary side disposed on a rotating side of the system. The rotary transformer is configured to couple primary power from an output of the primary power inverter to a primary power voltage output on the rotating side of the system, and is further configured to couple auxiliary power from an output of the auxiliary power inverter to at least one auxiliary voltage output on the rotating side of the system.

    摘要： Methods and systems are generally described for measuring a voltage used by an imaging system to generate radiation used in imaging. In embodiments, different datasets are acquired using different degrees of attenuation of the radiation. The differently attenuated datasets are processed to derive a ratio of the differential attenuation. The attenuation ratio is processed to derive a measure of the voltage used by the imaging system to generate the radiation used to acquire the different datasets.

    摘要： The present invention, in one form, is a method for detecting reference channel blockage in a computed tomography system. The system includes an x-ray source, a detector and a reference channel. When scanning an object of interest, the x-ray source is supplied with an x-ray source current and projects an x-ray beam toward the detector and the reference channel. The detector, when impinged by the x-ray beam, generates projection data for reconstructing an image of the object of interest. The reference channel is configured to generate an actual reference channel signal when impinged by the x-ray beam. An expected reference signal is determined in accordance with the x-ray source current. The expected reference signal is then utilized to normalize the projection data.
