Abstract: To speed up ICT image reconstruction, a PC/ DSP-based ICT image reconstruction system was designed.T he har dware buildup and working pr inciple of the system were introduced. Main contents of the device driver forPCI DSP signal processing board were discussed. Experimental r esult of ICT image reconstruction with the systemwas brought out . The experimental result indicated t hat, with the PC/ DSP-based ICT image reconstruct ion system,t he time needed for ICT image reconstr uction can be reduced efficiently and the working efficiency of ICT inspectionincreased.

Key words: digital signal processing (DSP), industrial computed tomography (ICT), image reconstruction, non destructive testing (NDT)
