    摘要： A method for calibrating a trabecular index with a sawtooth-shaped rack which corrects an error in the trabecular index due to the characteristics of an image input device or radiographic conditions of an x-ray image when a bone mineral density is measured by setting up the trabecular index with trabecular patterns of a simple x-ray image. The present invention includes a method for calibrating the trabecular index with a sawtooth-shaped rack, wherein bone mineral density is measured with the trabecular index calculated from an x-ray image and an error in the trabecular index is calibrated by a method of calibrating the trabecular index, the method includes the following steps. A first step is preparing an x-ray image by radiographing a bone and a sawtooth-shaped rack together. A second step is attaining trabecular indexes from the x-ray image of the rack and the bone. And, a third step is calibrating the trabecular index of the bone with the trabecular index of the rack.
