A feasibility study on the delectability of edema using magnetic induction tomography using an analytical model

Abstract

Magnetic induction tomography (MIT) is a low frequency electromagnetic modality, which aims to reconstruct the conductivity changes from coupled field measurements taken by inductive sensors. MIT is a subject of research for medical clinical applications where several reports have shown low conductivity tissue structures can be detected. The aim of this paper is to analyze the sensitivity of a single MIT channel to the central edematous region in a simplified head model. A multilayer model was used, which comprises concentric shells representing scalp, skull, cerebral spinal fluid, gray matter and white matter. An analytical solution of the electromagnetic field problem is presented and vali..
