1. A method for magnetic resonance imaging (MRI) using an MRI system having at least one coil, said method comprising:
- a. positioning a patient within the MRI system for MR imaging;
b. coupling a sensor to the patient and providing a sensor output signal representing a physiological event in the patient; and
c. applying at least one electrical pulse to the at least one coil triggered by said output signal of the sensor, and thereby emitting an audible sound from the at least one coil.

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.

7. A method for magnetic resonance imaging (MRI) using an MRI system having at least one coil, said method comprising:
-
a. positioning a patient within the MRI system for MR imaging;
b. coupling a sensor to the patient such that the sensor detects a recurring physiological event in the patient;
c. generating a sensor output signal when the sensor detects the physiological event in the patient;
e. applying the sensor output to generate at least one electrical pulse to the at least one coil, and f. emitting an audible sound from the at least one coil due to the application of the pulse, wherein the sound coincides with the physiological event. - View Dependent Claims (8)
