영문 초록

to define the suitable tube voltage in the gastrointestinal tract examination using barium sulfate. X-ray fluoroscopic unit with undertable tube system, fluoroscopic phantom equivalent to 21.5cm abdomen (CDRH phantom, Nuclear associates, USA), image quality test tool including high contrast resolution patterns and low contrast objects, and w/v 200% BaSo4 of 1mm thickness were used for this study. The test equipments were set up in the order of test tool, fluoroscopic phantom, and barium sulfate on the tabletop, and set the field of view (FOV) of to the mode 23cm(9inch) FOV. We exposed radiation to 5kVp increments from 60 to 125 kVp with automatic exposure controler (AEC) without and with barium sulfate, and then counted the number of high contrast mesh patterns and low contrast holes on the printed images. The number of high contrast mesh patterns and low contrast holes visible should be a minimum of 5 patterns and 6 holes on the printed images. In the test without barium sulfate, the number of high contrast mesh patterns(low contrast holes) was 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(6), 5(4), 5(4), 5(4), 4(4), 4(4), 4(4), at 5 kVp intervals from 60 to 125 kVp ,respectively. In the test with barium sulfate, the number of high contrast mesh patterns (low contrast holes) was also 5(5), 5(5), 5(6), 5(6), 5(6), 5(6), 5(5), 4(5), 4(5), 4(4), 4(4), 4(4), 4(4), 4(4), respectively. We propose that the suitable tube voltage in the gastrointestinal tract examination using barium sulfate is 85 kVp before and after, because a low kVp lengthens the exposure time.
