Abstract: An apparatus is provided for transferring data between a first device (34) and a second device (44), the second device being adapted to rotate with respect to the first device. The first device includes a first antenna assembly and a first transceiver assembly (37) for transmitting and receiving signals via the first antenna assembly. The second device includes a second antenna assembly and a second transceiver assembly (41) for transmitting and receiving signals via the second antenna assembly. The rotating antenna is mounted circumferentially about the second device such that the stationary antenna is in capacitive coupling relationship substantially through an entire revolution of the second device. The apparatus is particularly useful in a CT scanner where data is transmitted from the first device to the second device via a single channel, and data is transmitted from the second device to the first device via two time-multiplexed channels so as to provide high speed data transfer from second device to the first device at twice the rate of data transfer from the first device to the second device. The invention includes a variety of features for significantly reducing error rates, and particularly for reducing error due to cross talk between channels.

Abstract: Apparatus for energizing a large scale medical imaging system, preferably in the form of a CT scanner, so that the scanner operates off an uninterruptable power supply (40) in the event that the external power (46) falls below sufficient power to operate the system so that system operation remains uninterruptable. The system is designed to operate off a broad range and types of external power supplies (46) including those providing DC, single or three phase AC power. The system therefore can operate from a common single phase AC outlet. In addition, power factor correction (80) is provided so that the system can correct for phase differences between the voltage and current at the input line (46) created by the input impedance of the system.
