Control of thermal runaway and uniformity of heating in the electromagnetic rewarming of a cryopreserved kidney phantom.

Author(s) : PENFOLD J. D. J., EVANS S.

Type of article: Article

Summary

The authors introduce three stability factors which indicate whether thermal runaway can occur; they are dependent solely on the material's dielectric properties and the geometry and orientation of any irregularities. These factors provide clear guidelines to the choice of source frequency and applicator geometry that are favorable for intrinsic control of thermal runaway. Experimental results are presented for spherical phantom workpieces of 36- and 45-mm diameter, rewarmed from -90 to above 0 deg C in 30 to 150 seconds, in a 434-megahertz resonant cavity applicator.
