Abstract:
Objective To evaluate the causes of DR waste film rates in different characteristic cases,and provide basis for quality control.Methods DR waste film rates of 98 503 cases from PACS were analyzed.All cases were grouped according to gender,age,X ray projection direction and projection position.The differences of DR waste film rates between the groups were compared.Results DR waste film rate in 98 503 cases was 4.89％ and factors that caused waste film were incorrect position,foreign materials,motion artifacts,machine problems and inappropriate X ray dosage.DR waste film rate was affected by gender,age,X ray projection direction,but not affected by projection position.Conclusion Analysis of DR waste film rate in different characteristic cases could provide basis for the quality control to reduce the DR waste film rate.
