We describe a UHF rewarming system which has been used to measure warming rates, and particularly the uniformity of warming on three orthogonal axes, in a rabbit kidney phantom 36 mm in diameter. The stabilizing effect is demonstrated of using an E-field directed along the temperature gradient (or normal to any surface of dielectric discontinuity). One hot spot remains unaccounted for. The average warming rates and power dissipation are related to the volumetric heat capacity of the phantom material at -30 degrees C.
我们描述了一种超高频复温系统，该系统已用于测量直径为36毫米的兔肾模型中的复温速率，特别是在三个正交轴上的复温均匀性。展示了沿温度梯度（或垂直于介电不连续的任何表面）定向的电场的稳定作用。有一个热点仍无法解释。平均复温速率和功率耗散与-30摄氏度时模型材料的体积热容量有关。
