FAN Hua,ZOU Jianzhong,WANG Zhilong,LIU Yingjiang(Department of Biomedical Engineering,Chongqing Medical University,Chongqing Key Laboratory of Ultrasound Medical Engineering,Chongqing 400016,China)  
The selected fiber optic thermometer and MRI temperature sequence were used to synchronously monitor the temperature change of tissue-mimicking phantom during ultrasound exposure to investigate the feasibility of the MRI thermometry based on PRF theory.The result of experiments illustrates that this method can measure the temperature of target,but the accuracy and velocity of the method should need to improve further.
