Objective To explore the application value of PDCA quality management in calcaneal weight-bearing long-axis photographic image quality management.Methods The Quality Management Team of the adopted the PDCA image quality control management model to analyze the current situation of calcaneal weight-bearing long-axis photographic examination and the factors that contributed to the image quality decline.The specific factors contributing to the degradation of the image quality were identified,and solutions were developed and implemented.Paired chi-square tests were used to compare the frequency of high-quality calcaneal weight-bearing long-axis images taken before and after PDCA management.Results The paired chi-square tests revealed statistically significant differences between the two groups(X2=9.370,P=0.002).Conclusion PDCA image quality control management could improve the image quality of calcaneal weight-bearing long-axis radiographs and provide clinicians with a more reliable imaging basis for hindfoot anatomy,force line measurement,and the diagnosis of hindfoot malalignment.
