Method for shape sensing an optical fiber KU Leuven
A method for shape sensing an optical fiber embedded within at least a portion of an interventional device comprises the steps of obtaining, from at least one strain sensor, strain based shape sensing data of the optical fiber; Correcting the strain based shape sensing data with a strain correction term; calculating a strain based reconstructed shape of the optical fiber based on the corrected strain based shape sensing data; and mapping the strain based reconstructed shape of the optical fiber in a coordinate system, wherein the strain correction term is a predetermined strain correction ...
