摘要
设计了一种基于PC/DSP (PersonalComputer/DigitalSignalProcessor)的ICT (IndustrialComputedTomography)图像重建系统 ,论述了整个系统的硬件组成和工作原理 ,介绍了系统中PCI型DSP信号处理板的设备驱动程序的主要内容 ,给出了整个系统的试验结果。结果表明 :该系统能有效缩短ICT图像重建的时间 。
To speed up ICT image reconstruction,a PC/DSP based ICT image reconstruction system was designed. The hardware buildup and working principle of the system were introduced. Main contents of the device driver for PCI DSP signal processing board were discussed. Experimental result of ICT image reconstruction with the system was brought out. The experimental result indicated that,with the PC/DSP based ICT image reconstruction system,the time needed for ICT image reconstruction can be reduced efficiently and the working efficiency of ICT inspection increased.
