선속균일도(Beam Uniformity)를 확인하기 위하여 영상분석을 통해 히스토그램의 패턴변화와 평균 픽셀 값을 측정하였다. 필터의 두께에 따라 얻어진 원본영상을 영상분석 프로그램을 이용하여 히스토그램, 평균 픽셀 값을 시각화하고 정량화하여 선속균일도(Beam Uniformity)를 확인하였다. 본 연구는 디지털 방사선 촬영 검출기를 이용하여 필터 두께에 따른 선속균일도(Beam Uniformity) 실험방법을 제안하고자 한다. 필터의 두께 증가와 3D Surface Plot을 확인하였을 때, 평균 에너지가 감소하는 것을 확인할 수 있었으며, 표준편차 값이 감소되어 선속균일도(Beam Uniformity)가 증가된 것을 확인하였다. 따라서 본 실험에서는 영상분석을 통한 선속균일도(Beam Uniformity)를 간접적으로 확인할 수 있었다.
