Method for obtaining trabecular index using trabecular pattern and method for estimating bone mineral density using trabecular indices

摘要

A method for obtaining a trabecular index using a trabecular pattern displayed on an X-ray image and a method for estimating a bone mineral density using trabecular indices are disclosed. The method for obtaining the trabecular index analyzes trabecular pattern changes, due to decalcifications of trabeculae, displayed on the X-ray picture and quantifies the changes, thereby obtaining the trabecular index. The method for estimating the bone mineral density obtains trabecular indices and then estimates the bone mineral density corresponding to the trabecular index using a functional relation between the trabecular index and actual bone mineral density.
