TECHNIQUES FOR TEMPERATURE MEASUREMENT AND CORRECTIONS IN LONG-TERM MAGNETIC RESONANCE THERMOMETRY
摘要
<p>Techniques for temperature measurement and correction in long-term MR thermometry utilize a known temperature distribution in an MR imaging area as a baseline for absolute temperature measurement. Phase shifts that arise from magnetic field drifts are detected in one or more portions of the MR imaging area, facilitating correction of temperature measurements in an area of interest.</p>
