    Abstract:

    The purpose of developing Teaching Experiment Instrument of CT is to demonstrate the whole process of CT scanning more intuitively, thereinto the design of data acquisition system is one of the emphases in the developing of the CT system. This paper mainly introduces the design and implement of the data acquisition system of CD - 50BG, using CPLD apparatus which have the characteristic of high integration, in the design of data acquisition system to achieve the target of minishing system bulk and improving system reliability. Aiming at the data loss of CD - 50BG during acquiring data, the data acquisition system is reformatively redesigned, the data loss in the high speed data acquisition process is reduced so that the stability of transmission has been improved by using FIFO.
