These studies indicate that optical fiber FBG shape sensing technology has become a mature and reliable method for medical instruments. However, their sensing accuracy requires
We have described for the first time a fibre-optic ultrasound sensor-based real-time US needle tracking system with dynamic electronic focusing. With US focus tracking, the electronic focus

In this paper, the authors present a method for directly visualizing the needle tip using an integrated fiber-optic ultrasound receiver in conjunction with
In this work, we compare two different types of FBG sensors under identical conditions and application, namely, acting as the sensor for needle insertion shape reconstruction.
vivo tissue on the same experimental platform. In this work, we found that for shape-sensing in phantom tissue, the two needles performed identically with a p-value of 0.164 > 0.05, but in ex-vivo real tissue,
A fibre-optic, Fabry-Pérot interferometer hydrophone is integrated into an intraoperative needle and used to localise the needle tip within a handheld
The results demonstrate that ultrasonic needle tracking with a fibre-optic transmitter is feasible in a clinically realistic fetal surgery environment, and that it could be useful to guide minimally invasive
In this paper, we directly compare single-core fiber-based and multicore fiber-based needle shape-sensing through identically constructed, four-active area sensorized bevel-tip needles inserted into
Another promising method for MIS guidance is shape sensing of the needle based on the fiber optic sensors. Optical fiber characteristics, like biocompatibility, small size, and low mass18 make
The system is based on four optical fibers glued along the needle at 90 degrees from each other to measure distributed strain along the needle from four diferent sides.
In this paper, we directly compare single-core fiber-based and multicore fiber-based needle shape-sensing through identically constructed, four-active area sensorized bevel-tip needles
In this work, we propose and experimentally assess a shape-sensing guidance system based on four simultaneously scanned distributed optical fiber sensors based on high-scattering nanoparticle

Fibre-Optic Photoacoustic Beacon and 2D Sparse Sensor Array for 3D Tracking of Needles Abstract: Accurate knowledge of the needle tip location during percutaneous procedures such as liver and
Here, a method to track the needle tip during ultrasound image-guided procedures is presented. This method involves the use of a fiber-optic ultrasound receiver that is affixed within the
This paper shows the manufacture of a 300 µm lab-in-fiber sensor integrated in a surgical needle. It includes an air micro-cavity and a Pl-b-Pl FBG, allowing to detect a medium change and the
The device works by transmitting pulses of ultrasound from our proprietary low-cost fibre-optic trackable needle which are detected by a sparse sensor array located on the patient''s skin.
Nowadays, epidural space identification is made by using subjective and manual techniques characterized by failure rates up to 7%. In this work, we propose a fiber optic sensor
This paper presents the in vitro and ex vivo accuracy of a new, real-time, ultrasound needle tip tracking system for guidance of fetal interventions. A
