Abstract

A method for performing computer-assisted diagnosis includes receiving a plurality of two-dimensional views of an internal structure (S51), defining a search space around one or more areas of analysis within each view of the internal structure (S54), calculating a convex hull for each area of analysis within each search space of each view of the internal structure (S55), determining a set of foreground pixels that are located within the convex hull for each area of analysis within each search space within each view of the internal structure (S56), and for each area of analysis, merging the set of foreground pixels that are located within the convex hull from each view (S57).
