Abstract
Advantages of Air Cooling in Thermal Ablation

Thermal ablation is the method of destroying tumors through the application of extreme temperatures. For this experiment, heat is used and supplied by an amplifier/power generator. The heat is transported out through a catheter device and into the designated area of the tumor. Cooling the tip of the device can be used to control this heat in effort to expand the ablation size and cut down on the destruction of unwanted tissue. Thus far, water has been the primary strategy used for cooling. The practice of using an air-cooling device to improve thermal ablation has shown to be beneficial. Its effectiveness compared to water cooling and no cooling will be evaluated in this experiment. An air-cooling device has been created at 2.45 GHz. It will be tested ex vivo on pieces of meat and compared to the results of thermal ablation with water cooling and with no cooling at all. The air-cooling device is expected to show improved results compared to the other methods. This is due to air’s ability to deliver more energy to tissue as well as air requiring less space, thus allowing for a smaller needle for insertion. The goal is that these air-cooling devices will produce a much larger ablation zone while being less invasive and more time efficient than a device with water cooling or no cooling. In finding that air-cooling is a much more improved method over water cooling, doctors practicing thermal ablation will be able to target a varying amount of tumors in a safe and timely manner.
