Abstract

Objective To investigate the differences in image resolution between Computer X-ray Radiographs(CR) and Normal X-ray Radiographs.Method 200 chest CRs were compared with 200 normal chest X-ray radiographs,and the percentages of class-A,class-B,class-C radiographs and invalid radiographs were calculated respectively.Results The percentage of class-A radiographs in the CRs is 80%,while the 62% in the normal ones;the percentages of class-B,class-C and invalid radiographs in CRs are all lower than those in the normal ones.The differences are statistically significant.Conclusion The image resolution of CR is higher than that of the normal X-ray radiograph,and is more effective in clinical diagnosis.
