The objective of this study is to compare the two instruments (these are the two major instruments currently in use) listed for the measurement of bone mineral density and soft tissue readings. This is being performed to evaluate the methods for the next NHANES data collection effort. The investigator has been asked by the National Center for Health Statistics to perform this comparison. Fifty individuals aged 20-80 will be studied at this site (an addition 50 from USCF will also be studied). Same day scans will be performed. The data analysis is clearly outlined and based on correspondence attached to the protocol, the power to detect significant differences is present. This study was successfully completed. All volunteers were entered and the data analyzed. This data is used to help the National Health Examination Survey determine whether to use hologic dual energy x-ray absorptiometry equipment to perform body composition analysis in the next NHANES Survey.

本研究的目的是比较两种仪器（这是目前使用的两种主要仪器），用于测量骨密度和软组织读数。 这是为了评估下一个NHANES数据收集工作的方法。 国家卫生统计中心要求研究者进行这项比较。 将在该研究中心研究50名20-80岁的个体（还将研究来自USCF的另外50名个体）。 将在同一天进行扫描。 明确概述了数据分析，并基于随附于方案的通信，存在检测显著差异的把握度。本研究已成功完成。 所有志愿者都被输入并分析数据。 这些数据用于帮助国家健康检查调查确定是否在下一次NHANES调查中使用全息双能X射线吸收测量设备进行身体成分分析。
