RADIO FREQUENCY COIL TUNING METHODS AND APPARATUS
First Claim
1. A method of automatically tuning a radio frequency coil for use with a magnetic resonance imaging system using a tuning circuit connected to the radio frequency coil, the method comprising:
- determining information indicative of a Larmor frequency of the magnetic resonance imaging system; and
using a controller to automatically set at least one value of the tuning circuit to cause the radio frequency coil to resonate at approximately the Larmor frequency based on the determined information.

Abstract
Some aspects comprise a tuning system configured to tune a radio frequency coil for use with a magnetic resonance imaging system comprising a tuning circuit including at least one tuning element configured to affect a frequency at which the radio frequency coil resonates, and a controller configured to set at least one value for the tuning element to cause the radio frequency coil to resonate at approximately a Larmor frequency of the magnetic resonance imaging system determined by the tuning system. Some aspects include a method of automatically tuning a radio frequency coil comprising determining information indicative of a Larmor frequency of the magnetic resonance imaging system, using a controller to automatically set at least one value of a tuning circuit to cause the radio frequency coil to resonate at approximately the Larmor frequency based on the determined information.
