How Fiber Optic Sensors Measure Shape
Fiber optic shape sensing uses embedded sensors to measure the full 3D shape of a flexible surgical device along its entire length in real time. By sensing the device itself from the inside, it provides continuous awareness of how the device bends, twists, and turns as it moves. Fiber optic shape sensing has an outstanding capability to sense curvature and shape in 2D and 3D. The technology will enable cutting-edge applications in the fields of robotic and standard minimally invasive surgery – such as real-time position tracking, instrument and catheter navigation, force. In this work, we propose a novel, computationally efficient method for determining the 3D tip position of a bent multi-co...
