초록

본 실험에서는 전산화단층영상장비에서 패각을 이용하여 제작한 방사선 융합차폐체의 표면 방사선 감소율과 방사선 인공물 영상을 평가하고자 하였다. 방사선 융합차폐체는 실리콘, 패각, 바륨분말을 이용하여 직경 50 mm, 두께 3.5 mm의 원형 차폐체 5종 (실리콘 차폐체, 바륨 차폐체, 실리콘과 패각 혼합 차폐체, 실리콘과 바륨 혼합 차폐체, 실리콘과 패각 그리고 바륨 혼합 차폐체)을 제작하였다. 방사선발생과 획득은 4 다중채널 전산화단층영상장비를 이용하였다. 그 결과 실리콘과 패각 혼합 차폐체가 영상의 인공물 발생 없이 5.3%의 표면 방사선 감소효과가 있었다. 향후 다양한 형태를 만들 수 있는 실리콘의 장점과 패각의 재활용으로 인한 친환경적인 소재로 방사선 융합차폐체 제작에 도움을 줄 수 있으리라 기대한다.

The purpose of this present study was to evaluate the surface radiation dose reduction and radiograph artifact images in computed tomography (CT) for the manufactured radiation shields by using sea-shells. The radiation convergence shields were made from silicons, sea-shells, barium powders, producted circle types of diameter 50 mm, thickness 3.5 mm for 5 kinds (only silicon shield, only barium shield, mixed sea-shells with silicon shield, mixed barium with silicon shield, mixed sea-shells with barium and silicon shield). Radiation generation and acquisition were used 4-channel multi-detector CT. The results of this study showed that mixed sea-shells with silicon shields could reduce the surface dose of 5.3% without radiograph artifact images. In the future, we will expect the radiation convergence shield as environmentally friendly materials by using the recycling of sea-shells with the advantages of silicon which can make various shapes.
