Influence on Phase Detection of Magnetic Induction Tomography Using Insulated Container
摘要
Abstract
To study the influence of insulated container wall on measured phase of magnetic induction tomography(MIT).All of the containers were made of plexiglass which was insulated material.Saturated CaSO4 solution was injected into the containers.The containers were immerged into saturated CaSO4 solution in a cylindrical tank physical phantom.The phase shifts were measured before and after containers were immerged into.Two kinds of plexiglass containers were selected and two experiments were completed respectively.On the other hand, one solid plexiglass stick was immerged into saturated CaSO4 solution.The phase shifts were measured once per 1cm.The plot of phase shift with immerged depth was drawn.The ratio of the volume of two plexiglass container walls and that of the MIT phase shifts were closed.The plot of phase shift with immerged depth was approximately linear.The insulated plexiglass container wall is able to affect the measured phase data of MIT.Reducing the volume of container wall will mitigate the effect.关键词
