摘要
对大坝CT(ComputerizedTomography)技术的原理和标准ART算法作了介绍 ,在此基础上对ART算法进行了改进探讨 ,通过ART算法改进前后数字模拟试验的对比分析 ,说明改进后的算法在精度方面有了提高 ,异常体位置更明显 ,这将更好地满足大坝CT检测中的实际精度要求 .
The principle of computerized tomography of dams and the standard algebraic reconstruction techniques(ART) are described. On this basis the improvement of ART is discussed. Through comparative analysis of digital simulation results of before and after improvement of ART, it shows that the improvement algorithm is better in accuracy.
