    Abstract: A method for extracting a colonic centerline includes segmenting a colon from a digital image of a patient's abdomen, selecting one extreme point of the colon as a source point, calculating a first distance transform of every point in the colon that is a distance of a point to the source point, and calculating a second distance transform of every point in the colon, that is a shortest distance of a point to a wall point of the colon. A centerline path is generated through the colon using the first and second distance transforms, starting from a point with a greatest distance to the source point as determined by the first distance transform, and adding points to the centerline path by selecting points with a greatest distance to the source point that are farthest from the wall of the colon using the second distance transform.

    Abstract: A method and apparatus for guiding image reading for colon screening, includes calculating a centerline for a colon; scrolling through a succession of two dimensional (2D) cross-sectional images of a colon in respective image planes, such that a current image plane includes a respective current focus point formed by an intersection of the centerline with the current image plane. The method further includes performing a three-dimensional (3D) region growing process for growing a region of a suitable given thickness around a current seed point in a current image plane, the current seed point being at the respective current focus point in the current image plane, such that the region growing “floods” folds within a prescribed distance from the current seed point such that part of the region intersects the current image plane. Portions of the region intersecting the current image plane that meets at least one of conditions (A) and (B) are removed from consideration where: condition (A) includes the region intersecting the given current image plane containing a further connected component not containing the current seed point, and containing a further intersection of the image plane with the centerline other than the current seed point, and condition (B) includes the further connected component exhibiting a larger area than that exhibited by a connected component containing the current seed point; and marking remaining portions of the region intersecting the current image plane, not removed from consideration, as seen areas.
