Abstract
Provided are: a device () and a system () for quantitatively calculating bone density by using an X-ray image of a bone pail, in particular, an alveolar bone; and an imaging assisting tool () for accurately and easily performing X-ray imaging of an alveolar bone. This bone density measurement device () comprises: an image display unit () for displaying X-ray images for an imaged bone part and a reference body on the same screen; a reference body density measurement unit () for measuring the density of the displayed X-ray image for the reference body; a bone part density measurement unit () for measuring the density of the displayed X-ray image for the bone part; and a bone density calculation unit () for calculating the hone density of the bone part by comparing the density of the X-ray image for the bone part with the density of the X-ray image for the reference body.
