阻抗断层成像中的图像重建技术

Reconstruction Technology of Electrical Impedance Tomography

阻抗断层成像（Electricalimpedancetomography，EIT）是近年发展起来的一种新的医学影像技术，它具有成本低廉、无电离辐射、可以动态显示组织生理活动等优点，EIT图像重建一直是EIT技术中的重要研究课题。本文对EIT图像重建算法的发展作了评述。

Electrical impedance tomography(EIT) is a new medical image technology; it has the advantages of low cost, nonionizing radiation, and the capability of production images of physiological function dynamicaliy. EIT reconstruction has always been a project of importance to EIT researchers. In this paper, a review of the development of EIT reconstruction is presented.
