Femtosecond-Laser-Based Inscription Technique for Post-Fiber-Bragg Grating Inscription in an Extrinsic Fabry-Perot Interferometer Pressure Sensor

Duraibabu, Dineshbabu; Lacraz, Amedee; Kalli, Kyriacos; Tosi, Daniele; Leen, Gabriel; Poeggel, Sven; Lewis, Elfed (IEEE Sensors Journal, 2016-05-15)

In this paper, a novel fiber Bragg grating inscription technique based on a femtosecond laser is presented. The grating was inscribed in close proximity to the tip of an extrinsic Fabry-Perot interferometer (EFPI)-based ...
Fiber Bragg grating sensors for spatially resolved measurements in ex-vivo pancreatic laser ablation

Tosi, Daniele; Adilzhan, Abzal; Aliakhmet, Kamilla; Saccomandi, Paola; Schena, Emiliano; Silvestri, Sergio; Duraibabu, Dinesh Babu; Poeggel, Sven; Leen, Gabriel; Lewis, Elfed (Institute of Electrical and Electronics Engineers Inc., 2016-08-04)

Laser ablation (LA) is an emerging technology for mini-invasive treatment of tumors, and operates by damaging cancer cells by means of focused light-induced selective heating. In-situ temperature monitoring, with micro-sensors, ...
Fiber Optic Sensors for Temperature Monitoring during Thermal Treatments: An Overview

Schena, Emiliano; Tosi, Daniele; Saccomandi, Paola; Lewis, Elfed; Kim, Taesung (Sensors, 2016-07-22)

During recent decades, minimally invasive thermal treatments (i.e., Radiofrequency ablation, Laser ablation, Microwave ablation, High Intensity Focused Ultrasound ablation, and Cryo-ablation) have gained widespread ...
Intra-tissue pressure measurement in ex vivo liver undergoing laser ablation with fiber-optic fabry-perot probe

Tosi, Daniele; Saccomandi, Paola; Schena, Emiliano; Duraibabu, Dinesh Babu; Poeggel, Sven; Leen, Gabriel; Lewis, Elfed (Sensors (Switzerland), 2016-04-15)

We report the first-ever intra-tissue pressure measurement performed during 1064 nm laser ablation (LA) of an ex vivo porcine liver. Pressure detection has been performed with a biocompatible, all-glass, temperature-insensitive ...
Optical Fibre Pressure Sensors in Medical Applications

Poeggel, Sven; Tosi, Daniele; Duraibabu, DineshBabu; Leen, Gabriel; McGrath, Deirdre; Lewis, Elfed (Sensors, 2015-07-15)

This article is focused on reviewing the current state-of-the-art of optical fibre pressure sensors for medical applications. Optical fibres have inherent advantages due to their small size, immunity to electromagnetic ...
