摘要
磁感应成像(MIT)是一种无创和非接触的针对生物组织电导率分布的功能性电阻抗成像技术。MIT有以下优点:穿透性好、快速、便捷、低成本和无创,故其在医学成像上有很好的应用前景。MIT的研究包括系统结构、传感器、正问题和重构算法几个方面。本文阐述在MIT成像原理的基础上,对其重构算法的研究现状进行综述,对主要的重构算法进行归纳总结,分析几种算法的特点和应用领域,最后指出未来的研究趋势。
Magnetic induction tomography（MIT） is a noninvasive and non-contact functional electrical impedance tomography technique for detecting the distribution of electrical conductivity in biological tissues. MIT has a good application prospect in medical imaging for its several advantages, such as good penetration, fast, convenient, low cost and noninvasive. The research of MIT includes system structure, sensor, forward problem and reconstruction algorithm. Herein the principle of MIT imaging is expounded; the research status of its reconstruction algorithm is reviewed; and the main reconstruction algorithms are summarized. Finally, the characteristics and application areas of various algorithms are analyzed, and the future research trends are envisaged.
