Classification: CPC A  G | IPC A  G

Claim 8:
9. A method, comprising:
producing flow images from beamformed data;
producing a tissue-flow mask from the beamformed data, wherein the tissue flow-mask consists of values from 0 to 1, indicating a probability that a given pixel of the flow image is blood flow, where a value of 1 indicates a voxel is blood flow, a value of 0 indicates the voxel is not blood flow, and a value between 0 and 1 indicates whether the voxel more likely is not blood or is blood;
mapping the flow images to create a volume;
identifying voxels of the volume belonging to a vessel based on the tissue-flow mask;
extracting a surface of a wall of the vessel to create a three-dimensional model of the vessel;
receiving a real-time optical feed of an interior of a cavity from an optical camera-based guidance system;
receiving a first tracking signal indicative of a first spatial location of a probe of the ultrasound imaging system;
receiving a second tracking signal indicative of a second spatial location of the optical camera-based guidance system; and
overlaying the optical feed with the three-dimensional model based on the first and second spatial locations; and
displaying the optical feed with the three-dimensional model overlaid thereover,
wherein the three-dimensional model is a dynamic model that visually presents pulsation of the flow.
