| Abstract: | 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. |
