Invasive thermometers with a thermo-couple or an optical fiber are widely employed in hyperthermia treatment. A non-invasive method is wanted, but we can not present one at present. Several results obtained in Japan on studies of non-invasive thermometry are as follows: Mizushina, after simultaneous measurement of microwave radiation of the three frequencies located between 1 to 4 GHz, determined in real-time temperature dependence on depth to 5 cm beneath the skin of a rabbit, Yamaura, with his 915 MHz-CT apparatus, obtained 0.4 degree C temperature resolution on the phantom made of a hot cylinder in a cool tank both filled with NaCl solution, and Amemiya et al., assuming use of an NMR apparatus, showed theoretically that temperature could be measured after about 1 minute with the error of +/- 0.5 degree C if one measures M0 parameter in focusing magnetic field mode.
带有热电偶或光纤的侵入式温度计在热疗中被广泛应用。人们需要一种非侵入性方法，但目前我们还无法提供。日本在非侵入性温度测量研究中获得的一些结果如下：水尻在同时测量位于1至4吉赫兹之间的三个频率的微波辐射后，实时确定了兔子皮肤下5厘米深度处的温度依赖性；山村使用他的915兆赫兹CT设备，在装满氯化钠溶液的冷箱中的热圆柱体模型上获得了0.4摄氏度的温度分辨率；阿部等人假设使用核磁共振设备，从理论上表明，如果在聚焦磁场模式下测量M0参数，大约1分钟后就可以测量温度，误差为正负0.5摄氏度。
