摘要
Abstract
Objective: To calculate the accepted radiation dose of subjects in one exposure process of digital X ray radiography (DR), and to obtain the parameters to satisfy clinical diagnosis demand by using the minimum radiation dose under without affecting image quality. Methods: According to EU directive proposal, the entrance radiation dose could be obtained by thermoluminescent detector and dose area method, and the exit dose could be derived from the feedback data of DR. The accepted dose of subjects in one exposure process of DR could be calculated based on the calculation of entrance and exit dose. Finally, the optimal dose was applied on subjects in DR and the change of image quality was observed. Results: The optimized radiation doses was able to meet the demand of clinical diagnosis, and the image quality also could meet the demand of clinical diagnosis by using optimized photographic parameters. Conclusion: Photographic images produced by the optimized DR parameters are proved through inspected image can meet the demands of clinical diagnosis, and it can avoid misdiagnosis.关键词
