Monitoring radiofrequency thermal ablation in liver tissue with Draw Tower Gratings
Radiofrequency thermal ablation (RFTA) is a medical procedure for post-screening treatment of lung, hepatic and kidney tumours via hyperthermia. In this application the FBG array has been mounted directly on the ablation device to measure the steep temperature gradient, providing real-time measurements at 5 points (1 FBG sensor/cm). This demonstrates the potential of embedding FBG arrays on ablation devices, in order to dynamically estimate the efficiency of the procedure and predict the ablation output.
