Fiber optic sensing for temperature control during laser ablation of cancer tissues

Laser Ablation (LA) is a minimally invasive tumor treatment, particularly valuable when conventional methods are unsuitable. LA utilizes laser energy delivered using an optical fiber, offering advantages like electromagnetic immunity and flexibility of the applicator. Challenges in achieving complete tumor destruction and minimizing collateral damage prompt the need for improved monitoring and LA control. Fiber optic sensors offer advantages over conventional methods, such as small size, electromagnetic immunity and biocompatibility. This study employs fiber Bragg grating array sensors for precise temperature monitoring and implements closed-loop temperature control based on these measurements. Preliminary findings show effective control of temperature, indicating the potential of fiber sensors use in LA as a promising technique to enhance the efficacy of cancer treatment.
