摘　　要：目的:为了解决程控X线机在教学和实验中存在的设备费用高、体积大等缺点,提出开发虚拟程控X线机的方案。方法:以VB和SQL数据库为平台,利用上位机ActiveX控件开发虚拟X线机操作台,完成曝光参数的设定与显示、曝光过程、器官程序摄影等功能,同时设计下位机系统完成旋转阳极启动及延时、灯丝预热和曝光过程。上位机与下位机以通讯方式完成数据和命令的传送。结果:该虚拟X线机不但功能齐全而且费用低、使用方便。结论:对于其它医学仪器的虚拟设计,该方案具有重要的参考价值。Objective： In order to solve X equipment＇s disadvantages of high cost and huge bulk during the courses of teaching and experiment, the paper offered a notion of virtual X equipment. Methods： The virtual operator was designed by using upper computer＇s ActiveX control based on VB and SQL database, and it can realize the setting and display of radiography parameters, the progresses of radiography and organic radiography. The lower computer system was designed to simulate rotating anode＇s starting and delay, warming-up and exposure. All parameters and commands were sent by means of communication between lower computer and supper computer. Results： The result of experiment shows that the virtual X equipment has advantages of complete function, lower cost and convenience. Conclusions： This scheme can be applied to other kinds of medical instruments.
