We propose a new method for non-invasive measurement of structural properties of radiographic trabecular pattern for a quantitative characterization of trabecular bone architecture. The method actively searches for radiographic shadows that originate from individual trabecular elements. These shadows are used for measuring structural properties of trabecular bone. Filtering with Gabor wavelets is used to produce orientation and scale-specific channels for the extraction of trabecular structures. We give a design of the Gabor wavelet for his application. The performance of our method is visualized with radiographs form various anatomical sites showing the outlines of the detected trabecular elements superimposed on the radiograph.
