Abstract

An integrated optical shape sensing system and method include an arrangement structure (132) configured to receive a fiber port or connector. A platform (130) is configured to provide a distance relationship with the arrangement structure such that the fiber port or connector is trackable to provide a location reference. The platform secures a patient in proximity to the arrangement structure. An optical shape sensing enabled interventional instrument (102) has a first optical fiber cable connectable to the fiber port or connector. An optical interrogation module (108) is configured to collect optical feedback from the instrument and has a second optical fiber cable connectable to the fiber port or connector such that a known reference position is provided for accurate shape reconstruction.

Claims

1. An integrated optical shape sensing system, comprising:

an arrangement structure (132) configured to receive one or more fiber ports or connectors;

a platform (130) configured to provide one or more distance relationships with the arrangement structure, the platform for securing at least a portion of the patient in proximity to the arrangement structure such that the one or more fiber ports or connectors are trackable to provide a location reference;

an optical shape sensing enabled interventional instrument (102) having a first optical fiber cable connectable to the one or more fiber ports or connectors; and

an optical interrogation module (108) configured to collect optical feedback from the instrument and having a second optical fiber cable connectable to the one or more fiber ports or connectors such that the one or more fiber ports or connectors provide a known reference position for accurate shape reconstruction.

2. The system as recited in claim 1, wherein the arrangement structure (206) is connected to at least one side of the platform.

3. The system as recited in claim 2, wherein the one or more fiber ports or connectors (306) are adjustable in the arrangement configuration (305).

4. The system as recited in claim 2, wherein the one or more fiber ports or connectors (205) are adjusted in accordance with at least one of a patient size and a procedure type.

5. The system as recited in claim 1, wherein the arrangement structure (610) includes a three-dimensional structure adjustably connected to the platform to permit the one or more fiber ports or connectors to be positioned over the platform.

6. The system as recited in claim 4, wherein the three-dimensional structure includes windows (612) for imaging a patient on the platform.

7. The system as recited in claim 1, wherein the platform includes a moveable pad (402) that includes the arrangement structure.

8. The system as recited in claim 1, wherein the arrangement structure (508) is wall-mounted or ceiling mounted.

9. The system as recited in claim 1, further comprising a reference arm length control module (142) configured to adjust a reference arm length of an interferometer (134) in accordance with at least one of patient size, procedure type and system configuration.

10. An integrated optical shape sensing system, comprising:

an arrangement structure (132) configured to receive one or more fiber ports or connectors such that the one or more fiber ports or connectors are trackable to provide a location reference;

a table (130) configured to receive the arrangement structure;

an optical shape sensing enabled interventional instrument (102) having a first optical fiber cable connectable to the one or more fiber ports or connectors;

an optical interrogation module (108) configured to collect optical feedback from the instrument and having a second optical fiber cable connectable to the one or more fiber ports or connectors such that the one or more fiber ports or connectors provide a known reference position for accurate shape reconstruction; and

one or more imaging devices (110) configured to image the interventional instrument using the location reference for image registration.

11. The system as recited in claim 10, wherein the arrangement structure (206) is connected to at least one side of the table.

12. The system as recited in claim 11, wherein the one or more fiber ports or connectors (306) are adjustable in the arrangement configuration (305).

13. The system as recited in claim 11, wherein the one or more fiber ports or connectors (205) are adjusted in accordance with at least one of a patient size and a procedure type.

14. The system as recited in claim 10, wherein the arrangement structure includes a three-dimensional structure (610) adjustably connected to the table to permit the one or more fiber ports or connectors to be positioned over the table.

15. The system as recited in claim 14, wherein the three-dimensional structure includes windows (612) for imaging a patient on the table.

16. The system as recited in claim 10, further comprising a reference arm length control module (142) configured to adjust a reference arm length of an interferometer (134) in accordance with at least one of patient size, procedure type and system configuration.

17. The system as recited in claim 10, wherein the one or more fiber ports or connectors include visible markers to permit registration between the imaging system and the instrument.

18. A method, comprising:

providing (702) an integrated optical shape sensing system having an arrangement structure configured to receive one or more fiber ports or connectors such that the one or more fiber ports or connectors are trackable to provide a location reference, a platform configured to provide one or more distance relationships with the arrangement structure, an optical shape sensing enabled interventional instrument having a first optical fiber cable connectable to the one or more fiber ports or connectors and an optical interrogation module configured to collect optical feedback from the instrument and having a second optical fiber cable connectable to the one or more fiber ports or connectors such that the one or more fiber ports or connectors provide a known reference position for accurate shape reconstruction;

connecting (706) the first and second optical cables to at least one of the fiber ports or connectors;

securing (710) at least a portion of the patient in proximity to the arrangement structure; and

shape sensing (712) the instrument by employing a position of the at least one of the fiber ports or connectors as a reference.

19. The method as recited in claim 18, wherein the one or more fiber ports or connectors are adjustable (704) in the arrangement configuration in accordance with at least one of a patient size and a procedure type.

20. The method as recited in claim 18, wherein the arrangement structure includes a three-dimensional structure (610) adjustably connected to the platform to permit the one or more fiber ports or connectors to be positioned over the platform and the method further comprising imaging (716) a patient on the table through a window in the three-dimensional structure.

21. The system as recited in claim 18, further comprising adjusting (714) a reference arm length of an interferometer in accordance with at least one of patient size, procedure type and system configuration.
