Vascular reformatting using curved planar reformation

摘要

A method for curved planar reformation of an image includes receiving a data volume including a medial axis tree of a vessel tree, determining a global rotation axis of the medial axis tree, and casting a line segment from a vessel tree root of the medial axis tree into a predefined direction perpendicular to the global rotation axis. The method includes projecting the medial axis tree onto a reference plane along the line segment. The method further includes re-sampling, from at least one medial axis point of a reference plane, the data volume using a vector perpendicular to a medial axis tangent of the reference plane, wherein the vector defines a sampling direction. The method includes rendering an image of the vessel tree along the vector.

1. A computer-implemented method for curved planar reformation of an image comprising:
receiving a data volume including a medial axis tree of a vessel tree, wherein each medial axis of the medial axis tree bifurcates an area between adjacent branches of the vessel tree; determining a global rotation axis of the medial axis tree; casting a line segment from a vessel tree root of the medial axis tree into a predefined direction perpendicular to the global rotation axis; projecting the medial axis tree onto a reference plane along the line segment; re-sampling, from at least one medial axis point of a reference plane, the data volume using a vector perpendicular to a medial axis tangent of the reference plane, wherein the vector defines a sampling direction; and rendering an image of the vessel tree along the vector.
