摘要： An effective and highly accurate method for measuring temperature during thermal tumor ablation to increase ablation accuracy includes installing a fiber optic temperature sensor with a linearly chirped (the variation of the refractive index has a period growing in an algebraic progression) Bragg grating with a length of 1.4-6 cm and a diameter of 80-300 μm using a catheter directly on the tumor. Through the fiber optic sensor with a length of 1.4-6 cm and a diameter of 80-300 μm is passed a light spectrum, which undergoes backscatter due to the Bragg grating, dependent on the temperature acting on the sensor. Subsequently, using the backscatter light spectrum decoding software, developed according to the fiber optic cable parameters, the temperature profile is displayed on the computer. The method has applications in medicine, in particular oncology.
