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 …

We demonstrate a novel approach to enhance the precision of surgical needle shape
tracking based on distributed strain sensing using optical frequency domain reflectometry …

We present a prototype of a flexible nitinol needle (φ 1.0 mm and length 172 mm) integrated
with an array of 12 Fiber Bragg Grating (FBG) sensors. These sensors measure the axial …

The use of optical sensors inside the needle can improve targeting precision and can bring
real-time information about the location of the needle tip if necessary, since a needle bends …

Purpose Fiber Optic RealShape (FORS) is a new technology that visualizes the full three‐
dimensional shape of medical devices, such as catheters and guidewires, using an optical …

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 …

Needle insertion procedures are commonly used for surgical interventions. In this paper, we
develop a three-dimensional (3D) closed-loop control algorithm to robotically steer flexible …

Needle insertions are common during surgical procedures. Accurately delivering the needle
at a specific location in the human body is of importance for the clinical outcome of the …

Flexible bevel-tipped needles are often used for needle insertion in minimally invasive
surgical techniques due to their ability to be steered in cluttered environments. Shape …

Robotic needle steering requires accurate spatial information about the needle tip.
Presumably, fiber Bragg gratings (FBGs) can provide this information at an appropriate …
