Method and apparatus for MRI compatible communications

摘要

An MRI compatible communication system is disclosed. An interface module manages communications between devices within and external to the MRI scan room. The interface module also translates messages between varying wireless communication standards and protocols for retransmission to other devices. The communication system is configurable to transmit and/or receive data between physiological sensors, the MRI controller, patient monitoring devices, patient entertainment devices, and other computers. The interface module is configurable to be placed either in the control room or in the scan room.

主权项

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.
