Abstract :
Experiments comparing radiometric infrared tissue surface temperature measurement techniques during surgical ablation procedures to contact-probe measurements demonstrated substantial correlation between the measurement modalities. Thermal monitoring during surgical ablation guides therapy and prevents tissue damage in adjacent structures. RF ablation procedures on a canine kidney were monitored concurrently with a radiometric microbolometer array and fiber-optic thermal probe. Comparative analyses at select monitoring points established a substantial correlation between the recorded temperature values.
