HUB DESIGN AND METHODS FOR OPTICAL SHAPE SENSING REGISTRATION
First Claim
1. A hub for optical shape sensing instruments, comprising:
- a longitudinal body forming a cavity configured to receive two or more optical shape sensing (OSS) enabled instruments; and
one or more mechanical features disposed within the cavity or on the longitudinal body to maintain the two or more OSS enabled instruments in a fixed geometrical configuration relative to one another such that distally to the longitudinal body the two or more OSS enabled instruments have shape sensed reconstruction data registered therebetween.

Abstract
An optical shape sensing hub includes a longitudinal body (210) forming a cavity configured to receive two or more optical shape sensing (OSS) enabled instruments. One or more mechanical features (212, 214) are disposed within the cavity or on the longitudinal body to maintain the two or more OSS enabled instruments in a fixed geometrical configuration relative to one another such that distally to the longitudinal body the two or more OSS enabled instruments have shape sensed reconstruction data registered therebetween. The disclosed hub can be used in a shape sensing system to determine shapes of OSS enabled instruments. It is further disclosed a method for registering two or more OSS enabled instruments by generating a hub template of an expected shape of the hub in OSS data, searching measured OSS data to match the hub template to determine a hub position in the OSS data and finding overlap in the OSS data relative to the hub position.

16. A method for registering two or more an optical shape sensing (OSS) enabled instruments, comprising:
-
providing an optical shape sensing hub comprising a longitudinal body forming a cavity configured to receive two or more optical shape sensing (OSS) enabled instruments, and one or more mechanical features disposed within the cavity or on the longitudinal body to maintain the two or more OSS enabled instruments in a fixed geometrical configuration relative to one another such that distally to the longitudinal body the two or more OSS enabled instruments have shape sensed reconstruction data registered therebetween; generating a hub template of an expected shape of the hub in OSS data; searching measured OSS data to match the hub template to determine a hub position in the OSS data; and determining a registration between the two or more OSS enabled instruments by finding overlap in the OSS data relative to the hub position.
