Abstract
An MRI imaging system provides an audible feedback signal in the gantry room triggered by a physiological sensor on the patient. The feedback signal is a sound generated by one of the MRI gradient coils. The sensor output signal may be indicative of the patient's heartbeat, or other physiological event. The application of the sequence causes the coil to emit a sound that is associated with the sensor output signal.
