    • The present embodiments relate to active thermal control of X-ray tubes, for example X-ray tubes used in CT imaging. In one embodiment, a system for thermal control of an X-ray tube is provided. The system includes an X-ray tube having an electron beam target, a rotary bearing supporting the target in rotation, and a coolant flow passage, at least a portion of the coolant flow passage being disposed in the center of the rotary bearing, and the coolant flow passage is configured to receive a coolant. The system also includes a coolant circulating system coupled to the coolant flow passage and configured to circulate the coolant thorough the coolant flow passage, and a control circuit coupled to the coolant circulating system and the rotary bearing, the control circuit being configured to control heat flow between components of the X-ray tube by regulating extraction of heat from the X-ray tube via the coolant and by regulating a rotation rate of the rotary bearing.

    • A detector or a modulator for converting between optical and radio frequency signals comprising an optical guide (11 to 14) for propagating two optical signal components having frequencies that differ by an amount corresponding to a radio frequency and a microstrip radio signal guide (15, 16) for propagating a radio signal at the radio frequency, the microstrip radio signal guide being in travelling-wave coupling with an interaction one (14) of the optical guide comprising material in which interaction between the optical signal components and the radio signal occur. The microstrip radio signal guide element (15, 16) comprises an electrically conductive strip (15) juxtaposed with and extending along the interaction zone (14) on one side thereof and an electrically conductive ground plane (16) juxtaposed with and extending along the interaction zone (14) on an opposite side thereof. Transition radio signal guide elements (20,21) in the form of Vivaldi antennas extending transversely to the microstrip (15) connect the microstrip radio signal guide element (15,16) with a rectangular section wave-guide (18) and a matched load. Each of the transition radio signal guide elements (20, 21) comprises an opening of progressively varying width formed in the electrically conductive ground plane of the microstrip guide (16). Radio frequency signal resonators (24 to 27) extend the ends of the microstrip (15) and the small ends of the Vivaldi antennae.

    • A multiplex bus interface enables power and data to be transmitted and received on a two wire bus. Input and output devices operate with transceivers connected to the bus to communicate with each other by placing their data on the bus within specific time slots controlled by a controller, a clock module which broadcasts data to all connected transceivers. A pulsed power waveform provides power to the transceivers and data through pulse width modulation of the pulsed waveform. Data from the transceivers is transmitted during a time slot between power pulses. Data integrity is checked by the initiating input transceiver. Errors are reported at the end of a broadcast cycle. Output transceivers use the data as appropriate for the device and condition being monitored or controlled.
