DESIGN AND ANALYSIS OF A FBER‑OPTIC SENSING SYSTEM FOR SHAPE RECONSTRUCTION OF A MINIMALLY INVASIVE SURGICAL NEEDLE

Issatayeva, Aizhan; Amantayeva, Aida; Blanc, Wilfried; Tosi, Daniele; Molardi, Carlo (Nature Research, 2021-04-21)

This paper presents the performance analysis of the system for real-time reconstruction of the shape of the rigid medical needle used for minimally invasive surgeries. The system is based on four optical fibers glued along ...
DISTRIBUTED 2D TEMPERATURE SENSING DURING NANOPARTICLES ASSISTED LASER ABLATION BY MEANS OF HIGH-SCATTERING FIBER SENSORS

Ashikbayeva, Zhannat; Aitkulov, Arman; Jelbuldina, Madina; Issatayeva, Aizhan; Beisenova, Aidana; Molardi, Carlo; Saccomandi, Paola; Blanc, Wilfried; Inglezakis, Vassilis J.; Tosi, Daniele (Nature Research, 2020-07-28)

The high demand in effective and minimally invasive cancer treatments, namely thermal ablation, leads to the demand for real-time multi-dimensional thermometry to evaluate the treatment effectiveness, which can be also ...
Distributed fiber optics 3D shape sensing by means of high scattering NP-doped fibers simultaneous spatial multiplexing

Beisenova, Aidana; Issatayeva, Aizhan; Iordachita, Iulian; Blanc, Wilfried; Molardi, Carlo; Tosi, Daniele (OSA Publishing, 2019-08)

A novel approach for fiber optics 3D shape sensing, applicable to mini-invasive bio-medical devices, is presented. The approach exploits the optical backscatter reflectometry (OBR) and an innovative setup that permits the ...
DISTRIBUTED SENSING NETWORK ENABLED BY HIGH-SCATTERING MGO-DOPED OPTICAL FIBERS FOR 3D TEMPERATURE MONITORING OF THERMAL ABLATION IN LIVER PHANTOM

Beisenova, Aidana; Issatayeva, Aizhan; Ashikbayeva, Zhannat; Jelbuldina, Madina; Aitkulov, Arman; Inglezakis, Vassilis; Blanc, Wilfried; Saccomandi, Paola; Molardi, Carlo; Tosi, Daniele (Sensors, 2021-01-27)

Thermal ablation is achieved by delivering heat directly to tissue through a minimally invasive applicator. The therapy requires a temperature control between 50–100 ◦C since the mortality of the tumor is directly connected ...

FIBER-OPTIC BASED SMART TEXTILES FOR REAL-TIME MONITORING OF BREATHING RATE

Issatayeva, Aizhan; Beisenova, Aidana; Tosi, Daniele; Molardi, Carlo (MDPI, 2020-06)

Wearable light textiles are gaining widespread interest in application for measurement and monitoring of biophysical parameters. Fiber optic sensors, in particular Bragg Grating (FBG) sensors, can be a competitive method ...
FIBER OPTIC DISTRIBUTED SENSING NETWORK FOR SHAPE SENSING-ASSISTED EPIDURAL NEEDLE GUIDANCE

Amantayeva, Aida; Adilzhanova, Nargiz; Issatayeva, Aizhan; Blanc, Wilfried; Molardi, Carlo; Tosi, Daniele (MDPI, 2021-11-11)

Epidural anesthesia is a pain management process that requires the insertion of a miniature needle through the epidural space located within lumbar vertebrae. The use of a guidance system for manual insertion can reduce ...
Multi-fiber distributed thermal profiling of minimally invasive thermal ablation with scattering-level multiplexing in MgO-doped fibers

Beisenova, Aidana; Issatayeva, Aizhan; Sovetov, Sultan; Korganbayev, Sanzhar; Jelbuldina, Madina; Ashikbayeva, Zhannat; Blanc, Wilfried; Schena, Emiliano; Sales, Salvador; Molardi, Carlo; Tosi, Daniele (OSA Publishing, 2019)

We propose a setup for multiplexed distributed optical fiber sensors capable of resolving temperature distribution in thermo-therapies, with a spatial resolution of 2.5 mm over multiple fibers interrogated simultaneously. ...
