Quantifying probe deflection for improved catheter identification

A system, comprising:

• a shape sensing enabled medical device having a body which includes one or more imaging devices and a plurality of optical fibers that are distributed through a length of the shape sensing enabled device, wherein there is a greater concentration of the optical fibers in portions of the shape sensing enabled device which are closer to the one or more imaging devices than in portions which are farther away from the one or more imaging devices;
• a shape sensing module, wherein the shape sensing module is configured to receive optical signals from the plurality of optical fibers while the one or more imaging devices are disposed within a structure, and wherein the shape sensing module is configured to interpret the optical signals to determine a shape of the shape sensing enabled medical device;
• a device positioning module configured to determine position information of the one or more imaging devices based upon:
• (1) spatial relationships between the plurality of optical fibers and one or more points representing the one or more imaging devices, and (2) the determined shape of the shape sensing enabled device, wherein the spatial relationships are determined prior to placing the one or more imaging devices within the structure;
• and
• a mapping module configured to register frames of reference of the plurality of optical fibers, the one or more imaging devices, and a mapping system of a target device, wherein the mapping system of the target device determines a mapped position of the target device,
• wherein the mapping module is configured to provide an adjustment of the mapped position of the target device to determine a true position of the target device, wherein the adjustment is based on the position information of the one or more imaging devices, and wherein the true position takes into account deflection and/or bending of the shape sensing enabled device.

A method, comprising:

• collecting shape sensing data from a shape sensing enabled device which includes one or more imaging devices disposed within a structure, wherein the shape sensing enabled device has a body and is coupled to a plurality of optical fibers, and wherein the plurality of optical fibers are distributed through a length of the shape sensing enabled device, with a greater concentration of optical fibers in portions of the shape sensing enabled device which are closer to the one or more imaging devices than in portions which are farther away from the one or more imaging devices;
• receiving optical signals from the plurality of optical fibers;
• interpreting the optical signals to determine a shape of the shape sensing enabled device;
• determining position information of the one or more imaging devices based upon:
• (1) spatial relationships between the plurality of optical fibers and the one or more imaging devices, and (2) the determined shape of the shape sensing enabled device;
• registering frames of reference of the plurality of optical fibers, the one or more imaging devices, and a mapping system of a target device, wherein the mapping system of the target device determines a mapped position of the target device;
• and
• providing an adjustment of the mapped position of the target device to determined a true position of the target device, wherein the adjustment is based on the position information of the one or more imaging devices, and wherein the true position takes into account deflection and/or bending of the shape sensing enabled device.
