A Dynamic Programming Approach for Heart Segmentation in Chest Radiographs

 Chest radiographs are the most routinely acquired exams, which makes their use for diagnosis cost effective. In this paper we present a dynamic programming approach for automated heart segmentation on posterior-anterior (PA) chest radiographs. The goal of the proposed algorithm is to provide an accurate and reproducible method for heart segmentation, which can then be used to detect certain cardiac abnormalities. Our method has several advantages over previous methods, and provides superior performance to previously published results.
