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, P<0.05); DR waste film was 1.4%, CR rate of waste film 9.4%, DR radiography rejection rate was significantly lower than on the CR (x2=6.541, P<0.05), the difference was statistically significant. DR at the receiver radiography kV and mA seconds on the overall value slightly lower than CR, but the difference was not statistically significant (t=0.6784, t=0.7541;P>0.05). 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.关键词
