1. A CT-scanner having a gantry comprising a stator and a rotor, wherein an X-ray source and array of X-ray detectors are mounted to the rotor for determining absorption of X-rays along paths through the body of a patient imaged by the CT-scanner, the CT scanner comprising:

  • a processor that processes data comprised in signals generated by the X-ray detectors responsive to intensity of X-rays from the X-ray source incident on the detectors to generate an image of the patient;

    at least one spread spectrum transmitter that receives data comprised in the signals generated by the X-ray detectors and transmits signals encoded with the data in accordance with a spread spectrum coding; and

    at least one spread spectrum receiver that receives the encoded signals transmitted by the at least one spread spectrum transmitter and forwards the encoded data to the processor.
