An improved slip-ring has a stator and a rotor, and includes a brush having a proximal end mounted on one of the stator and rotor and having a distal end engaging the other of the stator and rotor. The brush is adapted to convey electrical signals across the interface between the stator and rotor. The improvement includes: the rotor including a support member (); and a track provided on the other of the stator and rotor, the track being arranged for sliding contact with the brush distal end; and a thermal element (or) arranged within the support member for selectively affecting the temperature of the rotor; whereby the temperature operating range of the slip-ring may be increased.

A computerized tomography (CT) system having an apparatus and method for receiving high data rate communication is disclosed herein. The apparatus includes a controlled variable attenuator for attenuating an encoded digital data signal having a wide range of power levels, a digital envelope detector for de-encoding the encoded digital data signal, a noise filtering circuit for filtering out the residual undesirable encoded signal components, and a feedback loop for maintaining a desired signal level such that the encoded digital data signal is converted to its pre-encoded state suitable for processing to generate a CT image.

RF slipring receiver for a computerized tomography system

An optical slip ring system provides for the transfer of information between a rotating frame and a stationary frame. The optical slip ring system includes a modulated light source, an optical fiber ring for receiving modulated light from the modulated light source and a signal conditioner. The modulated light source is attached to either the rotating frame or the stationary frame. The optical fiber ring is attached to the opposite frame. The optical fiber ring includes a first optical fiber and a second optical fiber. The first and second optical fibers each include a first and second end. The first end of the first optical fiber is coupled to a first terminator and the second end of the first optical fiber is coupled to a detector. The first end of the second optical fiber is coupled to a second terminator and the second end of the second optical fiber is coupled to the detector. The signal conditioner is coupled to the detector and restores data edges of the transferred information using an external clock.
