Abstract
Described herein are systems, methods, and computer-readable media for catheter-based birefringence mapping for an ablation procedure. A system includes a catheter that includes optical fibers coupled to a computing device that includes a processer that may create a three-dimensional map that displays optical properties of a tissue using optical measurements, specifically birefringence measurements, and a mapping system.
Claims20
A method, comprising:
- receiving, by one or more processors, a three-dimensional map of an organ of an animal, wherein the three-dimensional map comprises coordinates;
- receiving, by the one or more processors, an optical measurement of a tissue in the organ and a position of the optical measurement in the organ from a catheter comprising an optical fiber;
- determining, by the one or more processors, a coordinate in the three-dimensional map that corresponds to the position of the optical measurement;
- extracting, by the one or more processors, a birefringence measurement from the optical measurement;
- generating, by the one or more processors, a visual representation of the birefringence measurement;
- and
- modifying, by the one or more processors, the three-dimensional map at the coordinate to show the visual representation of the birefringence measurement at the coordinate, the modifying creating a modified three-dimensional map.
A system comprising:
- a catheter, wherein the catheter collects an optical measurement of a portion of a tissue in an organ of an animal and a position of the optical measurement in the organ;
- a plurality of optical fibers located within the catheter;
- a position sensor located within the catheter;
- and
- a computing device coupled to the plurality of optical fibers through a connector, the computing device comprising a processor and a memory having instructions stored thereon that, when executed by the processor, cause the processor to:
- receive, by the processor, a three-dimensional map of the organ, wherein the three-dimensional map comprises coordinates;
- receive, from the optical fibers, the optical measurement collected from the catheter;
- receive, from the position sensor, a position of the optical measurement collected from the catheter;
- determine, by the processor, a coordinate in the three-dimensional map that corresponds to the position of the optical measurement;
- extract, by the processor, a birefringence measurement from the optical measurement;
- generate, by the processor, a visual representation of the birefringence measurement;
- and
- modify, by the processor, the three-dimensional map at the coordinate to show the visual representation of the birefringence measurement at the coordinate, the modifying creating a modified three-dimensional map.
A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
- receiving a three-dimensional map of an organ of an animal, wherein the three-dimensional map comprises coordinates;
- receiving an optical measurement of a tissue in the organ and a position of the optical measurement in the organ from a catheter comprising an optical fiber;
- determining a coordinate in the three-dimensional map that corresponds to the position of the optical measurement;
- extracting a birefringence measurement from the optical measurement;
- generating a visual representation of the birefringence measurement;
- and
- modifying the three-dimensional map at the coordinate to show the visual representation of the birefringence measurement at the coordinate, the modifying creating a modified three-dimensional map.
