Patent ID: 8500694

Claim:
A liquid infusion system configured to facilitate wireless communication between a liquid infusion apparatus within a magnetic resonance imaging (MRI) scan room and a wireless remote external to the MRI scan room, comprising: a liquid conduit, a pump disposed to receive the liquid conduit and to transfer a liquid from a liquid source through the liquid conduit in response to activation of the pump, an actuator configured to provide mechanical movement to the pump to provide displacement of the liquid from the liquid source through the liquid conduit, a wireless transceiver configured to receive input control information from a remote control and transmit pump operation information to the remote control; a local controller configured to communicate with the actuator and the wireless transceiver to control transfer of liquid from the liquid source through the liquid conduit at a controllable volumetric rate, a communication port that provides a wireless communication link with the remote control, wherein the wireless communication link operates within a frequency range that is at least an order of magnitude higher than an operating frequency range of MRI equipment such that the wireless communication link does not interfere with operation of the MRI equipment, and wherein the local controller operates in conjunction with the remote control such that the pump is capable of operating without the remote control or if communication between the pump and the remote control is interrupted.
