Performance of CR and DR imaging characteristics and clinical application of comparative study / 中国医学装备

ABSTRACT

Objective: To evaluate CR (Computer X-ray imaging system) and DR (digital X-ray imaging system) imaging performance, features, advantages and disadvantages, and for application-level comparative analysis instrumentation for clinical application of scientific and rational resource reference. Methods:In the city diethyl hospital radiology shot 852 CR and DR tablets were retrospectively analyzed, focusing on the performance evaluation of two components as affecting the quality characteristics and radiography, focusing compare their clinical applications. Results:CR imaging quality was 89.9%, DR was 94.8%, DR radiography quality is higher than the CR, the difference was statistically significant(x2=7.864, P0.05). Conclusion: CR and DR mutual advantages and disadvantages, CR flexible, and lower cost, but the DR over CR has a higher spatial resolution, wider dynamic range and lower X-ray radiation, and a low rate of waste film radiography speed, high work efficiency. Suggest playing two advantages for clinical applications to provide more choices.
