Abstract

총 5대를 대상으로 한 진단용X선발생장치(DR)는 IEC 60601-2-54 표준규격에서 제시한 방사선출력의 재현성 시험에서 4대가 적합으로 나타났으며, 다만 1대의 X선 장치에서 C Group의 시험 설정인 진단용X선장치의 최고 관전압의 50%와 관전류 시간 곱(mAs)이 <TEX>$1{\mu}Gy$</TEX>에서 <TEX>$5{\mu}Gy$</TEX> 사이의 인가출력량의 조합으로 측정한 항목에서 부적합으로 나타났다. 이에 따라 방사선량을 정량화하기 위한 표준으로 IEC 60601-2-54 표준규격에서 제시한 방사선출력의 재현성이 진단용 X선 영상장치 성능관리에 중요한 평가 요소임을 인식해야 한다. For five diagnostic X-ray generators (DR), four units turned out to be appropriate in tests on the reproducibility of radiation output suggested in the IEC 60601-2-54 standard, but in one unit of the X-ray equipment, an item measured in a combination of 50% of the highest tube voltage of the diagnostic X-ray equipment, the test setting of Group C with authorized output doses between <TEX>$1{\mu}Gy$</TEX> and <TEX>$5{\mu}Gy$</TEX> of mAs turned out to be inappropriate. As a result, the radiation dose to the IEC 60601-2-54 standard for quantification standards proposed by the radiation output from diagnostic X-ray imaging device reproducibility of performance management should be aware that an important evaluation factor.
