摘　　要：通过计算机模拟的方法改进了60Co集装箱检测系统的指标估算的方法,结果CI和IQI指标估算值与实测值较好地吻合。CI (Contrast Indicator), IQI( Image Quality Indicator) and SP( Steel Penetration) are the important indicators in the digital radiograph system. The estimating of them takes an important status in the system performance design. At present the estimate method is lack of the support from experiment and the result is distinct from the measurement. This paper uses the computer simulation method to estimate the indicators of the 60Co container inspection system and gets a very good result.
