  • Vascular reformatting using curved planar reformation
    Patent number: 8744146
    Abstract: 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.

  • Mining temporal patterns in longitudinal event data using discrete event matrices and sparse coding
    Patent number: 8583586
    Abstract: Methods and systems for event pattern mining are shown that include representing longitudinal event data in a measurable geometric space as a temporal event matrix representation (TEMR) using spatial temporal shapes, wherein event data is organized into hierarchical categories of event type and performing temporal event pattern mining with a processor by locating visual event patterns among the spatial temporal shapes of said TEMR using a constraint sparse coding framework.
