The data acquisition system is an important part of industrial computed tomography (ICT). How to guarantee the stability, reliability and communality of data acquisition system's performance has important significance in improvement of ICT whole function. This data transmittance mode within windows will be disturbed by other program's interruption to lose the requested data. So it needs to improve the original design of ICT's data acquisition system. The data transmittance mode is shifted from program inquiring to hard interruption and FIFO cache is installed in front of data channel in order to guarantee the stability, reliability of data acquisition and trans- mittance.
