摘　　要：智能x-光摄片系统(CR)是80年代开发的医用新技术。在5时×7时范围内对自制的 CR 扫描装置进行了测试,在 PC—AT 机上对扫描装置的会聚情况作了离焦和不离焦的各种模拟运算。并用二种实验方法进行了测定。实验结果和计算相附。装置的分辨率为10ep/mm,达到医学分辨率要求。CR(computed Radiography)is one of the advanced technology developed in eigh-ties.A laser scanning equipment was set up with the components used in our laboratory.Theresolution calculating of this equipment was done in size of 5 inch×7 inch by a PC-AT com-puter and the resolution measuring was also experimentized with two different methods.Theyare fit very well.The resolution of this equipment is 101 p/mm.It meets the medical require-ments.
