Abstract

The purpose of this study was to evaluate the radiolucency for the phantom output to the 3D printing technology. The 3D printing technology was applied for FDM (fused deposition modeling) method and was used the material of ABS (acrylonitrile butadiene styrene) resin. The phantom was designed in cylindrical uniformity. An image uniformity was measured by a cross-sectional images of the 3D printed phantom obtained from the CT equipment. The evaluation of radiolucency was measured exposure dose by the inserted ion-chamber from the 3D printed phantom. As a results, the average of uniformity in the cross-sectional CT image was 2.70 HU and the correlation of radiolucency between PMMA CT phantom and 3D printed ABS phantom is found to have a high correlation to 0.976. In the future, this results will be expected to be used as the basis for the phantom production of the radiation quality control by used 3D printing technology.

본 연구에서는 3차원(3-dimensional, 3D) 프린팅 기술로 출력된 팬톰에 대한 X선 투과성을 평가하고자 하였다. 3D 프린팅 방식은 용융적층조형(fused deposition modeling, FDM) 방식을 이용했으며 소재는 아크릴로나이트릴 뷰타다이엔 스타이렌(acrylonitrile butadiene styrene, ABS)을 사용하였다. 팬톰은 원통 모양으로 설계하였으며 전산화단층영상장비(computed tomography, CT)에서 획득한 단면영상으로 균일도를 측정하였다. X선 투과성 평가는 3D 출력된 팬톰 내부에 이온챔버를 삽입하여 실시하였다. 그 결과, 평균 균일도가 2.70 HU이었으며 기존 폴리메틸 메타크릴레이트(poly methyl methacrylate, PMMA) CT 팬톰과 3D 프린터로 출력된 팬톰에서 측정된 X선 투과성의 상관관계는 0.976로 높은 상관관계가 있는 것으로 나타났다. 향후 3D 프린팅 기술을 이용한 방사선정도관리 팬톰 제작에 기초자료로 활용할 수 있으리라 기대한다.
