| 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 biologica... |
