In this paper, two objective phantoms were selected to measure the reproducibility and accuracy of BMD (Bone Mineral Density)
according to the manufacturer and installation environment, and proposed a performance evaluation test item of DXA by statistical
analysis. As the aging population becomes more interested in osteoporosis, a variety of techniques are used in measurement methods.
Generally, there are DXA, QCT, and QUS methods, and the DXA method is currently the most widely used. The approval test of bone
densitometer using DXA method in Korea is carried out by applying almost the same standard as overseas. However, in Japan and
South Korea, it is recommended that the performance tests be presented. In Japan, the JIS standard is presented and the performance
test is conducted with the phantom conforming to the standard. However, since the guidelines for performance are not established in
Korea, the test is being conducted with the test standard suggested by the manufacturer / importer. This causes many problems
because the standards vary from the manufacturer.
