Radio Frequency ablation is a minimally invasive approach for the treatment of cancers. It is performed by inducing alternating current through the RF electrode that causes heat. The temperature needs to be precisely controlled to cause tissue necrosis (death of cells). RF equipment is used in combination with Fiber optic point sensors, typically GaAs sensors to control the power, energy, and exposure time at the treatment area.
Tissue temperature plays a critical role as change in temperature induces tissue alterations. So, the temperature distribution at the treatment area is responsible for the shape and size of the ablated volume, and must be carefully controlled, to prevent damage to healthy surrounding structures. The local thermal monitoring is essential in all the thermal ablation procedures and can be performed through Rugged Monitoring LSENS-B sensor.
