디지탈 X-선 촬영시스템의 영상특성 분석

Characterization of digital radiography system

We have investigated imaging performance of digital rediography system by measured several imaging properties such as sensitivity characteristic, scatter fraction, modulation transfer function and detective quentum efficiency. The results show that digital rediography system has linear sesitivity to incident energy, excellent scatter elliminaility and high detective quentum efficiency, but poor modulatio transfer function.
