Detection of Postmenopausal Alteration of Bone Structure in Digitized X-rays

摘要

The goal of this research is to investigate the effectiveness of trabecular bone characterization in X-ray images acquired by consumer digital cameras from the radiological films by the joint use of fractal and statistic parameters. We propose the classification of patients in the pre- and post-menopausal groups, based on the trabecular structure of the calcaneum bone. The bone structure is locally characterized in clinically-significant regions of interest by the usual fractal dimension and a parametric model of the gray-level histogram. The classification yields a 8.33% miss-detection and 16.66% false alarm rate.
