Method and apparatus for wireless monitoring of subjects within a magnetic field
First Claim
1. An apparatus for monitoring a conscious subject in a magnetic field, the apparatus comprising:
- a sensor adapted to detect a physiological parameter associated with the subject while being disposed in the magnetic field, the sensor being adapted to provide a sensed signal representative of the physiological parameter; and
a wireless transmitter responsive to the sensed signal, the wireless transmitter being adapted to wirelessly transmit a transmitted signal representative of the sensed signal while being disposed on the subject in the magnetic field, the apparatus being made substantially from non-ferromagnetic materials.

Abstract
An apparatus for monitoring a conscious subject, such as a rat or human, in a strong magnetic field, such as that generated by a magnetic resonance imaging (MRI) scanner, includes sensors and wireless transmitter. The sensors detect physiological parameters of the subject, and the transmitter sends a wireless signal representing the parameters. A system for monitoring a conscious subject in a magnetic field includes a wireless monitor, wireless interface, and computer. The wireless monitor includes the sensors, filters, microcontroller, and wireless transmitter. The wireless interface receives the signal from the wireless monitor and transmits a corresponding signal to the computer. A method of monitoring a conscious subject in a strong magnetic field includes disposing the sensor in the magnetic field, sensing a physiological parameter from the subject, providing a sensed signal representing the parameter, disposing a wireless transmitter on the subject, and transmitting a signal representing the sensed parameter.
