几种磁场方式电阻抗成像技术的新进展

摘要

本文介绍了4种磁场方式的电阻抗成像技术，分别为磁感应电阻抗成像技术、磁感应磁声成像技术、磁共振电阻抗成像技术、磁探测电阻抗成像技术，分析了每种技术的成像原理与研究进展，并指出电阻抗成像技术在临床医学方面具有广阔的应用前景。%This paper introduced the electrical impedance tomography (EIT) using four kinds of magnetic ifelds, including magnetic induction impedance tomography (MIIT), magnetoacoustic tomography with magnetic induction(MAT-MI), magnetic resonance electrical impedance tomography (MREIT) and magnetic detection electrical impedance tomography. After analyzing the imaging principle and research progress of each electrical impedance tomography, this paper pointed out that EIT using various magnetic ifelds would have a broad prospect in the ifeld of clinical medicine.
