Objectives To improve the accuracy of diagnosis of osteoporosis and promote the clinical use of dual - energy x - ray photon absorptiometry for assessment of osteoporosis. Methods The physical meaning of BMD and other relative parameter of DXA was described. The advantages and disadvantages of current absorptiometric techniques were presented. Results Identify the provision of means for the effective treatment of excessive bone loss groups of subjects at risk of fracture were put forward. Conclusion Bone measurement techniques may be widely used in medical science.
