| 摘 要： | 针对直接数字化X线（DR）系统的曝光控制过程较繁琐的问题提出改造方案．通过PC机的RS-232串行口与高压发生器进行数据交换．用软件实现了DR系统中高压发生器曝光参数的控制．为DR系统提供了更加方便的操作平台。实验表明该控制方案数据传输可靠．能满足曝光需要．可取代DR产品上原有的曝光控制台。

| Abstract: | A proposal is presented to improve the original complicated control of the exposure parameters in the direct radiography system (DR). The interface circuitry of the high-voltage generator is redesigned using RS-232 serial COM port. The data and signals are transmitted between the personal computer and the high-voltage generator in the serial mode. A program package is designed to realize the control of the exposure parameters of the high-voltage generator in DR on the PC machine. Experiment results have shown that the proposed console operates steadily and it is capable of providing a more convenient operation console for the direct radiography system. |
