摘要 电磁层析成像 (EMT)技术的逆问题至今没有完全解决 .在简单图像重建的基础上改进了 EMT的反投影算法 ,应用了可以解第一类 Fredholm 积分方程病态问题的L andweber迭代法 .通过重建结果的比较 ,L andweber迭代法是目前重建精度较高的 EMT重建算法 . Electromagnetic tomography(EMT) is a kind of process tomography technique based on inductance.The image reconstruction of EMT using the backprojection algorithm has low quality, so we use the Landweber iterative algorithm, which can deal with ill posedness of the inverse problem. The reconstructed images indicate that the Landweber iterative algorithm is a better algorithm for EMT nowadays.
