Abstract
Objective: This study evaluated the bone mineral density (BMD) values of a phantom in different models of bone densitometer of a particular brand, and difference estimated. Methods: The Norland series densitometers were applied to evaluate the BMD of a lumbar phantom. The Norland XR 600 was used to scan the lumbar phantom for 15 times and calibrated, and the data used as standard. The imitations were repeated under the same condition using other series of Norland. Results: The SigmaPlot v.12.5 was used to analyze collected data. Difference between standardized phantom BMD and other imitated BMD values was analyzed using one way ANOVA. The p value of bone density, bone content and bone area were less than 0.01, 0.01 and 0.05, respectively. The average of BMD values of different modalities was analyzed by Results (%True) of measurements, and homogeneity of BMD values was indicated. Conclusion: No obvious deviation was observed under different modalities, and the results of examinations may be used in relevant research.
