Clinical Practice of Multifunctional Direct Digital Radiography System / 实用放射学杂志

Objective To investigate multifunctional direct digital radiography system (DDR) in clinical practice, in order to improve the applied value of it.Methods EPEX DDR was performed in 1000 cases,these images were analysedby 3 senior radiologists and tried to find the best method of usually positions. Results The quality of DDR was assessed as grade A in73.00%, grade B in 22.70%, grade C in 4.30%, and no waste film.Conclusion DDR is easy to operate, fast in capturing image and can provide post-processing techniques, which will facilitate the accurate diagnosis of radiography.
