Abstract
An apparatus and method for correcting magnetic resonance temperature measurements is disclosed. In one aspect, the method identifies monitoring regions of interest outside a therapeutic region of interest. Next, a pulse sequence sensitive to changes in Tand proton density is used to measure the temperature changes in these regions. Next, the PRFS is measured in these same regions. The PRFS in these regions will be caused both by the desired shift from temperature change, and the undesired shift from background magnetic field changes. Using the measured temperature changes from the T-method, the component of the PRFS due to actual temperature changes is subtracted from the PRFS method, leaving only the component caused by the unwanted magnetic field changes. This analysis is performed separately for each region. At the end of this step, one has measured the change in background magnetic field within each region.
