EFFICIENT IMAGE RECONSTRUCTION ALGORITHMFOR ELECTRICAL IMPEDANCE IMAGING

电阻抗成像技术正取得进展,并开始用于人体诊断。电阻抗成像的优点是对人体无害及其硬件远比X射线层析成像(X-CT)低廉,是一项需引起重视的科研课题。 本文提供了一种基于低频电流场灵敏度矩阵研究的迭代方法作为图像重建算法,并取得了令人满意的计算机模拟结果。

<ABSTRACT> Electrical impedance imaging techniques are obtaining improvement and beginning to work at human body clinic. Electrical impedance imaging has the advantages of reduced biological hazard and less expensive hardware. An efficient image reconstruction algorithm presented here is an iteration approach based on the research for sensitivity matrix of the low-frequency current field and the results are satisfactory.
