中文摘要：

Magnetoacoustic 断层摄影术把电的阻抗断层摄影术的优点与 sonography 相结合。它能重建有高空间的分辨率和高度的生物织物的传导性图象形成对照。另外， magnetoacoustic 断层摄影术是一种新非破坏性的功能的成像技术，我们能与认识到人的疾病的早诊断。在这份报纸，通过理论分析，我们推出了声学的压力的分析公式。有当前的注射(MAT-CI ) 的 magnetoacoustic 断层摄影术上的计算机模拟和试验性的研究被做，并且一枚铜戒指为模拟和实验被用作模型。试验性的安装和方法被介绍，并且声学的信号和借助于 MAT-CI 的一个金属对象的图象被介绍。模拟和实验的结果在一个好协议。声学的来源的重建的图象能反映一件样品的传导性信息。一件样品的传导性分发能借助于 MAT-CI 被获得。结果为 MAT-CI 在一个模型上向学习的基础提供复杂传导性分发和纸巾。

英文摘要：

Magnetoacoustic tomography combines the advantages of electrical impedance tomography with sonography. It can reconstruct conductivity images of biological tissue with high spatial resolution and high contrast. In addition, magnetoacoustic tomography is a new nondestructive functional imaging technology, with which we can realize the early diagnosis of human diseases. In this paper, through theory analysis we deduced the analytical formula of acoustic pressure. Computer simulation and experimental studies on magnetoacoustic tomography with current injection （MAT-CI） were made, and a copper ring was used as the model for the simulation and experiment. Experimental setup and methods are introduced, and the acoustic signals and the image of a metal object by means of MAT-CI are presented, Results of the simulation and experiment were in a good agreement. The reconstructed image of an acoustic source can reflect the conductivity information of a sample. The conductivity distribution of a sample can be obtained by means of MAT-CI. The results provide foundations of study on a model with complex conductivity distribution and tissues for MAT-CI.
