项目摘要

Magnetic Induction Tomography (MIT) is a relatively new, non-invasive imaging technique which has applications in both industrial and clinical settings. In essence, it is capable of reconstructing the electromagnetic parameters (permittivity, permeability and conductivity) of an object from measurements made on its surface. An MIT device consists of two sets of coils placed around the boundary of the object to be imaged. The first set of coils is used for the purpose of excitation, and by passing a current through each coil in turn, a primary magnetic field is created. The second set of coils is then used for measurement. This procedure causes an eddy current when each of the primary magnetic fields interacts with a conducting body inducing secondary magnetic fields, and hence voltages, that are measured in the second set of coils.Enabling MIT to take the step from being an experimental technique, which has already received some clinical interest, to become a viable imaging technique for the detection and monitoring of conditions, such as cerebral stroke, requires a step change in the quality of the reconstruction of the electromagnetic parameters and, therefore, an improvement of the computational approach used for the solution of the inverse problem. To achieve this we propose to solve the inverse Maxwell problem with a variational algorithm. Although a proof of concept of this work exists, in order to make this algorithm effective in a clinical environment, and hence applicable to the MIT problem, an implementation using high performance computing is needed, this research proposal aims to address this issue.
磁感应断层成像(MIT)是一种相对较新的非侵入性成像技术,在工业和临床环境中都有应用。从本质上讲,它能够根据对物体表面的测量来重建物体的电磁参数(介电常数、磁导率和电导率)。MIT设备由放置在待成像物体边界周围的两组线圈组成。第一组线圈用于激励目的,并且通过使电流依次通过每个线圈,产生初级磁场。然后,第二组线圈用于测量。当每个主磁场与导电体相互作用时,该过程引起涡电流,从而感应在第二组线圈中测量的次级磁场和电压。使MIT能够从已经受到一些临床关注的实验技术迈出一步,成为用于检测和监测诸如脑卒中的状况的可行成像技术,需要在电磁参数的重建质量上的阶跃变化,并且因此需要用于求解逆问题的计算方法的改进。为了实现这一点,我们建议解决逆麦克斯韦问题的变分算法。虽然这项工作的概念证明存在,为了使该算法在临床环境中有效,因此适用于麻省理工学院的问题,需要使用高性能计算的实现,这项研究的目的是解决这个问题。
