摘要
对仿组织透明体模进行超声辐照使其发生温度变化,并通过光纤温度传感器和磁共振成像(MRI)测温序列对其进行同步监控研究,以探讨基于质子共振频率(PRF)理论的MRI测温方法的可行性,结果显示该方法能够测量靶区温度变化,但是其测温精度和测温速度均有待进一步提高。
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.
