Sumario:PURPOSE: The purpose of this study is to build a system for effective dose display immediately after the gastric cancer X-ray screening. MATERIALS AND METHODS: The regression equation of effective dose and dose area product (DAP) was introduced from the data of 500 persons including DAP and effective dose calculated using program for X-ray Monte Carlo. RESULTS: The effective dose was 5.39 mSv of median, 1.18 mSv of minimum, and 38.38 mSv of maximum. The regression equation was Y=0.354+0.0003772X (Y: effective dose, mSv, X: DAP, mGy cm(2)). Using the regression equation, the effective dose can be estimated from DAP and displayed just after the individual screening. CONCLUSIONS: “Effective dose display system” was constructed to display effective dose immediately after gastric cancer X-ray screening. This system is on the way to be reformed by improving the regression equation on larger data.
