Abstract
A method for visualizing branches of a lumen includes inserting (402) a fiber optic shape sensing device into a lumen and determining (404) changes in the lumen based upon strain induced in the fiber optic shape sensing device by flow in the lumen. Locations of branches are indicated (410) on a rendering of the lumen. An instrument is guided (414) to the locations of branches indicated on the rendering.
Claims16
A system for monitoring a blood vessel, comprising:
- a processor;
- a memory coupled to the processor;
- a fiber optic shape sensing device configured to be inserted in a blood vessel for providing shape sensing data indicating blood flow in the blood vessel;
- and
- a display,
- wherein the memory includes instructions, when executed by the processor, configure the processor to:
- map branches of the blood vessel based on changes to the blood flow,
- generate an overlay image based on the shape sensing data, the overlay image indicating a shape of the blood vessel and locations of the branches,
- determine a count of a number of sealed branches, and
- cause the display to render the overlay image over a rendering of the blood vessel to provide a guide for visualizing the branches of the blood vessel, and update the overlay image to display the count of the number of sealed branches.
