Abstract
Official abstract text for this publication.
An instrument system that includes a first optical fiber, a second optical fiber and a controller is provided. The first optical fiber is operatively coupled to an elongate body that is adapted to be placed inside a patient. The second optical fiber is operatively coupled to the patient, to an actuating element adapted to actuate the elongate body, or to a portion of an imaging system adapted to identify a location of the portion relative to the elongate body. The controller is operatively coupled to the first optical fiber and the second optical fiber and is adapted to receive a first signal from the strain sensor provided on the first optical fiber, receive a second signal from the strain sensor provided on the second optical fiber; and determine a position or orientation of the elongate body based on the first signal and based on the second signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An instrument system comprising: an elongate body; an optical fiber operatively coupled to the elongate body and having a strain sensor provided on the optical fiber, the optical fiber associated with a first coordinate system; a localization sensor associated with a second coordinate system; and a controller operatively coupled to the optical fiber and the localization sensor and adapted to receive a first signal from the strain sensor and a second si…
