摘　　要：电阻层析成像技术是近年来发展起来的一种截面分布式的检测技术,具有非侵入的、无辐射的、可视化的特点。在电阻层析成像技术中,图像重建是由测量到的边界电压重建出对象内部电阻率分布的过程,是最终实现ERT技术可视化测量的过程。图像重建算法,直接影响成像的效果。本文介绍了目前比较常用的图像重建算法的原理以及应用过程中的优缺点。Electrical Resistance Tomography technology is an advanced section-detection technology that is developed recently, and it has the following characteristics： non-invasion, non-radiation, visualization. In Electrical Resistance Tomography technology, image reconstruction is to get the resistivity distribution in the object using the measured marginal voltage, and it is the last step to realize the visualization of the object. Image construction arithmetic is to influence the effect of the image. This paper introduces several kinds of image reconstruction arithmetic that has been used very common, and it introduces their principles and the good and bad aspects in their application.
