| Abstract:: |
| Objective To study the changes in the image quality of radiographic films and the irradiation doses to patients after quality control (QC) implementation. Methods The entrance surface doses (ESD) to patients measured with TLD and the image quality of radiographic films were evaluated on the basis of CEC image quality criteria. Results The ESD to patients were significantly reduced after QC implementation (P<0.01 or P<0.05)23% for chest PA,48% for lumbar spine AP and LAT,88% for pelvis AP.In comparison with pre QC,the post QC image quality of lumbar spine LAT was not significantly changed (P>0.05),but the post QC image quality was significantly improved in chest PA,lumbar spine AP and pelvis AP(P0.01 or P<0 05). Conclusion Significantly reduced irradiation dose with improved image quality can be obtained by QC implementation. |
