Abstract

Diagnostic imaging systems play a critical role in obtaining anatomical images, which increases the frequency of inspection all over the world. However the likelihood that patients are exposed to relatively high radiation dose increases, which may lead to an increase of patient dose due to unnecessary radiation exposure unless appropriate management is accompanied. Thus the revised edition of IEC 60601-2-44 which is constancy tests for CT equipment which is designated as special medical equipment and is subject to safety management was studied. The results suggested the 3rd has been revised rationally in order to overcome the limitations in the 2nd by adopting clear and enhanced references, which implies the replacement of IEC 60601-2-44 2nd edition with IEC 60601-2-44 3rd will prevent the patients from the harm from improper medical equipment.

본 연구에서는 해부학적 영상 획득에 중추적인 역할을 담당함에 따라 전 세계적으로 검사빈도가 증가하고 있다. 하지만, 환자가 받는 방사선량이 상대적으로 높아 적절한 관리가 이루어지지 않으면 과도하거나 불필요한 방사선 피폭으로 환자선량을 증가시킬 수 있다. 이를 위해 특수의료장비로 지정하여 안전관리를 시행하고 있는 전산화 단층촬영용장치의 항구성 시험 IEC 60601-2-44의 개정판에 대하여 문헌 조사하였다. 그리고 비교 및 분석을 통하여 새로운 요구 사항에 대하여 알아보고자 하였다. 문헌 조사 결과 개정된 3판(3rd Ed)에서는 명확하고 강화된 기준값을 적용하고 있고, 2판에서(2nd Ed)의 한계점을 해결하기 위하여 합리적으로 개정되었다. 그러므로 현재 국내에서 적용하고 있는 IEC 60601-2-44 2판을 개정된 IEC 60601-2-44 3판으로 적용한다면 부적합한 의료장비로 인한 환자의 위해를 막을 수 있을 것으로 사료된다.
