Abstract
Apparatus for measuring the bone density of the extremities of a human body. The apparatus includes an x-ray source for projecting a continuous spectrum x-ray beam through a body extremity region and a calibration wedge positioned adjacent to the body extremity region to produce x-ray images of the body extremity region and the calibration wedge; an x-ray image converter for converting the x-ray images into digital image signals representative of the x-ray images of the body extremity region and of the calibration wedge; and a digital image processor for processing by means of a segmentation technique the digital image signals representative of the x-ray images of the body extremity region and the calibration wedge to automatically determine the bone density of at least a portion of the body extremity region to establish whether or not there has been a loss of bone mass.
