Abstract

The purpose of this study is to evaluate the usefulness of a newly fusion model designed cloak shield to reduce the radiation exposure of the assistant during CT(computed tomography) of severely injured patient. Radiation dose was measured in the heart, both axillary and thyroid areas using newly designed cloak shield and existing shield with head phantom and human phantom under the same conditions as brain vascular CT scan. The newly designed cloak shield was measured higher for radiation shielding rate than the existing shields, 61.9 % for heart, 46.2 % for left axillary, 69.8 % for right axillary and 71.1 % for thyroid gland, respectively. a newly developed fusion model of cloak shields are useful for reducing radiation exposure. It is expected to make a significant contribution to reduction of radiation exposure.

중증외상 환자 CT(Computed Tomography)검사 시 검사 보조자의 방사선 피폭경감을 위하여 새로운 융합적 모델의 망토 차폐체를 제작하여 그 유용성을 평가하고자 한다. 실험 방법으로 뇌혈관 CT 검사와 동일한 조건에서 두부 팬텀과 인체 팬텀을 이용하여 기존 차폐체와 새롭게 개발된 망토 차폐체를 이용하여 심장, 양쪽 액와부 그리고 갑상샘 부위를 유리선량계로 피폭선량을 측정하였다. 새롭게 개발된 차폐체가 기존의 차폐체 보다 방사선 차폐율이 심장 61.9 %, 좌측액와부 46.2 %, 우측액와부 69.8 %, 그리고 갑상샘 71.1 % 로 각각 높게 측정되었다. 새롭게 개발된 망토 차폐체가 방사선 피폭을 감소시키는데 매우 유용하며 향후 새롭게 개발된 융합적 모델의 망토 차폐차가 방사선 피폭을 감소시키는데 있어 큰 기여를 할 것으로 판단된다.
