Aim of Study: Is to show the intrahepatic temperature development in anesthetized pig. Materials and Methods: Temperature development in the liver of anesthetized pig is measured to study the thermal effects of capacitive coupled energy transfer. The treatment was made by modulated electrohyperthermia (mEHT, trade name: oncothermia ®), controlled by a fluoroptical temperature sensing positioned by the ultrasound-guided process. Various fits of coupling were studied. Results: The intrahepatic temperature at the end of the treatment ranged 40.5–44.8°C, while the skin temperature ranged 36.8–41.8°C depending on the coupling arrangement. Conclusion: mEHT is a feasible method to deliver deep heat to the liver of an anesthetized pig.
