Abstract

The invention discloses a method, device and readable storage medium for determining a blood vessel centerline. The method includes: acquiring a blood vessel image; point and segmented line; construct an undirected graph according to the first starting point, junction point and segmented line; determine each connected component of the undirected graph; determine each subgraph in each connected component, the subgraph includes at least one vertex, when the subgraph When the graph includes multiple vertices, there are at least two connection paths between any two vertices in the subgraph; for each connected component, the subgraph including the first starting point is the root node, and the subgraph not including the first starting point is the root node. Sub-nodes and leaf nodes, using the connection lines between sub-graphs as edges, construct a spanning tree; obtain at least one specified point selected by the user for the blood vessel to be named; when the specified point does not include the second starting point, determine the root node in the spanning tree From the first path to the specified point, the second centerline of the vessel to be named is obtained.

Description

technical field [0001] The present application relates to the technical field of vessel naming, in particular to a method, device and readable storage medium for determining a vessel centerline. Background technique [0002] In the post-processing of medical head and neck artery CT images, it is necessary to determine the centerline of the head and neck vessels, and then reconstruct the corresponding curved surface or straightened image of the head and neck vessels according to the centerline of the head and neck vessels. The step of determining the vessel centerline is called vessel nomenclature. At present, blood vessel naming software is usually used to initially name blood vessels, and then the user adjusts the center line of the blood vessel point by point, and adjusts all points on the center line of the blood vessel to the center point of the trend of the blood vessel. Since there are many blood vessels in the head and neck and they are intertwined with each other, i...
