| Abstract: | Objective To explore the principles of the radiographic absorptiometry method in quantiative evaluation of bone mineral density.Methods The definition of osteoporosis was firstly explained in this paper,then common measurement methods of bone mineral density were introduced, and principles of radiographic absorptiometry medthod （RA） were emphatically introduced.Results RA technology didn＇t need to add any new equipment because it was based on the X-ray system. Conclusion RA medthod is one of the most accurate, convenient and quickest ways in the technical measurement of BMD currently and deserves widespread promotion. |
