Abstract
A device comprising includes an insertable structure usable in a surgical theater, a fiber optic line extending through the structure, wherein a computer system is configured to determine a shape of the fiber optic line extending through the structure, and one or more electromagnetic sensors wrapped at least in part around one or more portions of the fiber optic line, wherein the computer system is configured to determine a position and orientation of the one or more electromagnetic sensors, wherein the computer system is configured to determine a shape and a position of the structure based on the determined shape of the fiber optic line extending through the structure and the determined position and orientation of the one or more electromagnetic sensors.
Claims25
A system comprising:
- a computer system comprising a processor to execute instructions;
- an insertable structure usable in a medical environment;
- a fiber optic line extending through the structure;
- and
- two or more electromagnetic sensors wrapped at least in part around one or more portions of the fiber optic line, wherein the computer system is configured to determine a position and orientation of the two or more electromagnetic sensors, wherein the two or more electromagnetic sensors comprise:
