Bildverarbeitungsverfahren zur Erfassung von Strukturveränderungen bei gestörtem Skelettwachstum
Summary
Not only loss of bone mass but also changes in bone structure are important parameters for the degree of bone disease. In this paper a method is proposed that provides a procedure for quantitative determination of changes in bone structure. X-radiographs of trabecular bone regions are digitized and preprocessed in an image processing system. Subsequent two-dimensional FastFourier-Transformation generates a characteristic gray-scale pattern in the two-dimensional spatial frequency plane. Radial integration for each angular direction then provides characteristic gray-scale distribution that allows quantification of the regularity of bone structure.
