영문 초록

Purpose : To make an offer to the direction for minimizing the dose, we considered some measures and put the measure into practice. Materials and Methods : We measured the fluoroscopy dose with an SHMAIZU 3, HIDACHI 1, PHILIPS 2, and DAP meter (PD-4100L, Torex, Japan) from April 1 to September 18, 2009. We attached a DAP meter in front tube of the fluoroscopy equipment and calibrated the fluoroscopy equipment using a dose meter. We recorded the fluoroscopy time, a number of spot exposures and DAP before and after the activity of reducing the exposure dose. The results were compared with each other to suggest some effective ways of reducing the exposure dose. Results : 1. The average time of each examination was growing down except in colon study. It was distinguished to be reduced in the upper gastrointestinal series of 71.3% and small bowel series of 63.5%. 2. A number of spot exposure time was decreased in all examinations especially endoscopic retrograde cholangiopancreatography of 22.6% and voiding cystourethrography of 14.4% excluded in the upper gastrointestinal series. 3. This study indicated innovative results at reducing DAP which was the aim of this study. Conclusion : To reduce patient dose, we made a standard ourselves although there aren’t any standard DRL in Korea except in some examinations. It is a task of great significance to provide the data that would be a preliminary data for other hospitals that would need the data when they manage exposure doses. Exposure dose management is required for durability and repetitive doses so that it is the most important for a systematic management. For this we will concentrate on the maintenance and management exposure dose regular.
