objective: through the analysis of patients more film validation plan research, it is concluded that the factors affecting film dose verification, and set up my family film dose verification specification. Methods: 9 cases of film dose verification cases of low pass rate for the material, by changing the value of the leakage rate, dose rate, and verify whether before calibration, scanning time interval four factors comparison, a detailed analysis and research. Results: the factors influencing the film dose verification number are obtained. Conclusion: whether the leakage rate, dose rate, scale and scanning time interval is the important factors that affect film validation pass rate, strictly regulate the film dose verification process is the key to film dose verification.
