Optimization of the Monitoring Procedure for Determining the Ablation Zone in Ex-Vivo Bovine Liver

This work presents optimization studies for a novel microwave ablation zone monitoring concept based on phase-shift measurements. Several ablations are carried out on ex-vivo bovine liver with a power of 50 W and an ablation time of 10 minutes. The previous research status was that the ablation zone with the novel method could be predicted reproducibly, but with a mean deviation of 70.2% and a standard deviation of 4.1%. The results from this work show that the ablation zone can now be predicted with a mean deviation of 16.8% and a standard deviation of 5.6%.
