Abstract

We developed a new method to compensate the rib structures in digital x-ray images. The intrinsic information of rib structures is eliminated and a higher image quality for the diagnosis of pulmonal structures is achieved. An essential task of the algorithm is the robust detection of the rib borders. In this paper we introduce three algorithms to perform this task. The first, introduced by Schreckenberg and Joswig, uses the hough transform to find rib borders, the second one uses a synergetic classifier to estimate the matching between rib edge templates and rib borders. The last one, the sinking lead algorithm, gives the best classification results by performing a matched template technique in combination with partial methods from the former two algorithms.
