OBJECTIVE
To establish a set of evaluation system of digital radiography clinical value and provide foundation for the maturity assessment of digital radiography.
METHODS
The evaluation system of clinical value of digital radiography was established by literature survey,expert consultation,and percentage weight method.
RESULTS
The expert authority coefficients were 0.81 and 0.88,respectively.After two rounds of consultation,variation coefficients of each item ranged from 0 to 0.207,and the coefficient coordination were 0.599.The index system consisted of 5 first-level indexes and 12 second-level indexes.The weights of first-level indexes such as image quality,safety,usability,economic and social indicators share of the weight are 0.298,0.294,0.199,0.121 and 0.088 respectively.
CONCLUSIONS
A completed and scientific evaluation system was established,which provides a scientific assessment tool for clinical value of digital radiography.
