영문 초록

Purpose : This thesis is, esophagography, UGI series, swallowing study using DAP meter measure in checking and fluoroscopy time, body weight, to learn about the correlation with image number, compared with earlier studies and seek the ways of reducing the radiation dose. Materials and Methods : October- December 2008 was an experiment of 212 patients. Philips has used its equipment, DAP meter adherent in front of X-ray tube calibration, and using the ion-chamber. By checking the patients weight, fluoroscopy time, image number and DAP values were measured. Results : According to the increase in esophagography fluoroscopy time as an increase in the DAP had paid attention to statistics (P<0.05). In UGI series, according to the increase in weight, fluoroscopy time, image number as an increase in the DAP had paid attention to statistics (P<0.05). In swallowing study, fluoroscopy time and DAP had paid attention to statistics (P<0.05). In all test, depending on the increase in fluoroscopy time also DAP had increased gradually. In case of our hospital, the average DAP and fluoroscopy time with advanced studies to compare at least 2.4 times, respectively, 6.5 times as high was investigating. In UGI series, fluoroscopy time at least 1.7 times, DAP 2.6 times, image number also was 2.4 time higher. Conclusion : To reduce patient dose for fluoroscopy examination, in here and now, they should evaluate patient dose and accurately analyze related factors of exposure dose. It comes to the conclusion that patient dose is reduced in good image quality by perfonning the examinations for reference of advanced studies or recommend dose recommended dose in international organizations.
