| 摘 要： | 本文从阵列声波ＣＴ成象问题出发，阐述了用正则化方法作ＣＴ成象处理的原理和方法，即引入正则化因子，求泛函极小和构组一族正则化近似并从中寻求最佳解，算例分析表明，正则化方法作ＣＴ成象速度反演效果好。

| 关 键 词： | 阵列声波CT成象，正则化方法，速度反演 |

| Abstract: | Principle and method to process CT imaging by use of regularized method,are described inthis paper in accordance with the problem of array sonic log This method is characterized by introducing r.egularized factors evaluating functional minimum and constructing a group of regularized approximate solutions mith the desire of seeking for optimum solutoin. The analysis of caculation examples show that the effect of velocity inversion in CT imaging is good. |
