Abstract

The non-invasive temperature measurement with MRI (magnetic resonance imaging) is investigated, and the theory and methods based on the non-invasive temperature monitoring on T1 with MRI are discussed. A corresponding theoretical temperature model by means of the experimental data is given, and a comparison of the theoretical temperature with the measured temperature by using a thermometer is made. It is shown that the non-invasive temperature monitoring on T1 with MRI can obtain the temperature of the biological tissue with better accuracy and within 5 seconds, which makes it possible for the tissue temperature changes to be monitored in real-time and non-invasively.
