计算机射线照相系统与工业胶片在9MeV X射线照相中的性能对比

Performance of CR System and Industrial Film in 9 MeV X-ray Radiography

摘要: 采用9 MeV直线加速器X射线源,以工业胶片、VMI高性能5 100MS型CR(计算机射线照相)系统为影像介质,对钢板和固体发动机进行了射线照相,并对影像进行了对比.结果表明,灵敏度测试中CR成像系统性能介于中粒与细粒工业胶片之间,实际缺陷检测能力与中粒工业胶片相当.

Abstract: The performance of VMI 5100 MS CR system was studied.Metal plates and a solid propellant engine were radiographed by a 9MeV linear electron accelerator X-ray source.By comparing the radiographs of CR system and industrial films,conclusion was made that the resolution of CR system was between medium and fine grain films,and its performance was equivalent to medium grain film.
