The Research of Parallel Magnetic Field Tomography Based on Finite Element Method

The goal of parallel magnetic field tomography technology is to find out the distribution of materials with magnetic property via the measurement to the disturbance of magnetic field, as its sensor is sensitive to the conductive and magnetic conductive materials, also it is non-invasive, noncontact and non-hazard, so it has potential application in many field such as medical agency, industrial site etc. Based on the traditional CT (computer tomography) theory, the parallel magnetic field tomography system with finite element method is simulated in this article, the reconstruction images were gained, and the result shows that parallel magnetic field tomography can get the clear peripheral contour of the magnetic conductive materials.
