1. A communication system to permit communication between a patient undergoing a diagnostic imaging procedure in a scan room and a technologist in a control room conducting the diagnostic imaging procedure, wherein the diagnostic imaging equipment includes a scanner configured to generate a diagnostic image located in the scan room and a controller configured to control operation of the scanner located in the control room, the communication system comprising;

  • an interface module operable to transfer an audio signal between the control room and the scan room, the interface module including;

    an input connection configured to receive the audio signal from the controller,a wireless communication module configured to convert the audio signal to a radio frequency (RE) modulated signal having a frequency greater than a frequency of operation of the diagnostic scanner, andan output connection configured to conduct the RF modulated signal;

    an antenna located in the scan room and electrically connected to the output connection of the interface module and configured to transmit the RF modulated signal in proximity to the scanner; and

    at least one wireless receiver configured to be positioned in proximity to the scanner and to receive the RF modulated signal.
