title: Microwave leakage during patient treatment.
abstract: In light of the BRH proposed draft standard for microwave leakage of 10 mW/cm2, microwave leakage measurements were taken under two conditions. The first used a microwave tissue equivalent phantom in which leakage cata was accumulated as a function of net forward power and aperture-to-skin distance (SSD). This is similar to the BRH setup. In the second condition, during actual microwave hyperthermia treatments data was accumulated on several patients at different anatomical sites. The results of these experiments show a marked increase of microwave leakage occurring during patient treatment than that which can be predicted from static phantom results.
