System and method for data driven editing of rib unfolding

摘要

A method and apparatus for data driven editing of rib centerlines is disclosed. A user input location indicating an inaccuracy in a rib centerline extracted from a medical image volume is received. A local correction of the rib centerline is performed. A portion of the rib surrounding a current centerline point to be corrected is segmented based on image data of the medical image volume. A corrected centerline point for the current centerline point is generated based on the segmented portion of the rib. The centerline correction is then extended to subsequent points along the rib centerline.

1. A method for correcting a rib centerline
extracted from a medical image volume, comprising: receiving a user input location indicating an inaccuracy in a rib centerline extracted from a medical image volume; determining a centerline point to be corrected corresponding to the user input location by:
performing a local correction of the rib centerline in a vicinity of the user input location, resulting in a locally edited centerline, anddetermining a centerline point closest to the user input location on the locally edited centerline to be the centerline point to be corrected; segmenting a portion of the rib surrounding the centerline point to be corrected based on image data in the medical image volume; and generating a corrected centerline point for the centerline point to be corrected based on the segmented portion of the rib.
