Abstract:
1. A method for guiding image reading for colon screening, comprising: calculating a centerline for a colon to be screened; 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 said centerline with said current image plane; 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, said current seed point being at said respective current focus point in said current image plane, such that said region growing floods any folds within a prescribed distance from said current seed point and such that part of said region intersects said current image plane; and marking portions of said region intersecting said current image with a first mark.
