Abstract：Dual-energy X-ray absorptiometry is a kind of large medical equipment which can be used to test human bone mineral
density, bone mass, z value and other physiological data. GE-Lunar DPX-MD+ Bone Densitometer in our hospital is a widely used
conventional equipment of dual-use X-ray absorptiometry. The key components and basic principles of this bone densitometer was
briefly introduced. The details which should be paid attention to during the process of using and maintenance was emphasized. The
faults phenomenon of tube failure, detector failure and motor failure were emphatically introduced. Through analysis of the rules and
regulations, the interference factors were excluded, the fault locations were identified and the machine was maintained.
