ABSTRACT
Objective To analyze the metrological verification parameters and methods for dual-energy X-ray absorptiometry (DEXA) to facilitate magnitude traceability.Methods DEXA's principle was discussed from the aspects of dual-energy X-ray absorption method and hardware structure.The method combining corresponding theory and specifications was used to describe the measurement accuracy and repeatability as well as the verification method and data processing for radiation protection performance parameters.Theoretical analysis was executed on corresponding parameters.Results Theoretical analysis was carried out on the metrological verification parameters of DEXA from the aspects of principle structure and measuring method.Conclusion It's of great significance for enhancing DEXA metrological verification to master the metrological verification parameters and methods.
