Fully Distributed Chirped FBG Sensor and Application in Laser-induced Interstitial Thermotherapy

Not Accessible

Your library or personal account may give you access

Abstract

A fully distributed chirped Fiber Bragg grating (FBG) sensor is proposed to detect dynamic change of the temperature distribution of the tissue during laser induced interstitial thermotherapy (LITT). A simulated experiment of LITT is carried out, and the temperature distribution is acquired by the modified simulated annealing evolutionary (MSAE) algorithm.
