Abstract

Recently, There has been a growing interests in exposure dose to the patient who take a examination using radiation. The radiological technologists should be concerned about the exposure dose to patients and make an efforts to reduce the patient dose without decreasing the image quality. In the case of foreign, the exposure dose of general X-ray examination have been managed by standard value of exposure dose using dose area product (DAP) and entrance surface dose (ESD) dosimeter. This study is to compare DAP and ESD in skull anterior posterior (AP), chest posterior anterior (PA), and abdomen AP projections of phantom by using DAP and ESD dosimeter. In the results, there were no differences between DAP and ESD dosimeter.

최근에 방사선을 이용한 검사들은 환자들이 받는 피폭선량에 대한 관심이 증대하고 있으며, 이러한 방사선을 이용한 방사선사들은 X-선 검사 시 환자에게 조사되는 피폭선량을 인지하여 영상의 질 저하 없이 환자의 피폭선량경감에 대하여 끊임없이 노력해야 한다. 외국의 경우 일반촬영검사들의 피폭선량기준치로 면적선량계와 표면입사선량계에 의하여 선량관리를 하고 있다. 이에 본 논문은 모의팬텀을 이용하여 일반촬영검사들 중 두 개부 전후방 촬영, 흉부 후전방 촬영, 복부 전후방 촬영을 중심으로 면적선량계와 반도체 선량계를 이용하여 면적선량과 표면선량을 비교 측정하였으며, 그 결과 면적선량계와 반도체선량계와의 측정차이는 없었다.
