Dual energy X-ray absorptiometry (DXA) is a dominant technique for the\nmeasurement of bone mineral density (BMD). Quality control (QC) of DXA\nis very important for the accuracy of results and correct interpretation made\nby the physician. We have performed the quality control procedures of Lunar\nDPX Pro bone densitometer according to the manufacturerâ??s recommendations\nand current clinical guidelines at the Institute of Nuclear Medicine &\nAllied Sciences (INMAS), Khulna. The objective of this study is to maximize\nthe performance of the technologist as well as the reliability of the equipment\n(Linearity, X-ray tube output, Half value layer, Kerma-area product, Radiation\nfield size, Fan angle, Spatial resolution, Room safety). The study result\nshows that the mean BMD reading is 1.004 g/cm2 with a standard deviation of\n0.0035 and co-efficient of variation 0.34%. It also shows that the precision of\nthe technologist is good and there is no malfunctioning in the DXA bone\ndensitometer.
