Abstract: A triggering device includes an optical fiber (126) configured for optical shape sensing. A supporting element (104) is configured to support a portion of the optical fiber. An interface element (106) is configured to interact with the optical fiber associated with the supporting element to cause a change in a property of the fiber. A sensing module (115) is configured to interpret an optical signal to determine changes in the property of the fiber and accordingly generate a corresponding trigger signal.

Abstract: An optical shape sensing system includes an attachment device (130) coupled at an anatomical position relative to a bone. An optical shape sensing fiber (102) is coupled to the attachment device and configured to identify a position and orientation of the attachment device. An optical shape sensing module (115) is configured to receive feedback from the optical shape sensing fiber and register the position and orientation of the attachment device relative to an anatomical map.
