摘要: 介绍了X射线图像传感器要求的驱动信号源及时序关系。针对串接三片64像元的X射线图像传感器阵列的驱动要求以及实际应用中机械装置产生的外部同步信号参与X射线图像传感器驱动的情况,分别利用VHDL语言对驱动信号进行编程。设计完成后利用MAX+plusⅡ软件对其进行模拟仿真。实验结果证明了用VHDL程序设计X射线图像传感器驱动电路的可行性。Abstract: The required driving signals and the timing relationship of X-ray image sensor required were described. For the driving demand of the series connection of three 64 pixels X-ray image sensor and for the outer synchronization signal generated by mechanical device playing a part in the driving circuit in the practical applications, the programming idea of using VHDL for the required driving signal required was analyzed. The simulation experiments of the driving signals were made with software MAX+plus Ⅱ. The experimental results showed that design of the driving circuit of X-ray image sensor by VHDL was feasible.
