1. A wireless communication system, comprising:
- a transmitter including;
a control circuit operable to prepare a data packet for transmission,a transmit circuit in communication with the control circuit and operable to convert each data packet to a radio frequency (RF) signal for transmission, andan antenna in communication with the transmit circuit and operable to transmit the RF signal; and
a receiver including;
at least one antenna operable to receive the RF signal;
at least one receive circuit, each receive circuit in communication with the at least one antenna and operable to convert the RF signal to a data packet, anda control circuit in communication with each receive circuit and operable to extract data from the data packet, wherein;
the control circuit in the transmitter prepares the data packet for transmission at a periodic interval,the transmit circuit converts the data packet to a plurality of RF signals, each RF signal having a different frequency,the transmit circuit transmits each RF signal within the periodic interval, andthe receiver receives the RF signals at each of the frequencies, converts each RF signal back to the data packet, and verifies that the data packet was transmitted successfully.

Abstract
A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter'"'"'s processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.

12. A method of wireless communication, the method comprising the steps of:
-
receiving a data signal at a control circuit in a transmitter; generating a data packet which includes at least one value of the data signal in the control circuit; converting the data packet to a plurality of RF signals, each RF signal having a different frequency; transmitting each of the RF signals within a periodic interval; receiving each of the RF signals at a receiver in communication with the transmitter; extracting the data packet from each of the RF signals in a control circuit in the receiver; and evaluating the data packets to verify that the data packet was transmitted successfully. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
