  • Method and system for graph based interactive detection of curve structures in 2D fluoroscopy
    Patent number: 9195905
    Abstract: A method and system for detecting a curve structure in a 2D fluoroscopic image is disclosed. A plurality of curve segments are detected in the image. A graph is generated based on the detected curve segments. A curve structure is detected in the image by determining a path between a source node and a destination node in the graph. A hyper-graph can be constructed from the graph in order to impose geometric constraints on segments of the detected the curve structure, and the curve structure can be detected by finding a shortest path in the hyper-graph.
    Type: Grant
