Three- dimensional Effects in Electrical Impedance Tomography
نویسنده
چکیده
An investigation of 3-dimesional (3D) effects on electrical impedance tomography is reported. 3D effects in measurement, simulation and analytical models are described. A 3D attenuation range (75% attenuation) from the sensing plane is suggested as one third of process vessel’s diameter. The imaging trajectory of an axially moving object is found towards the central axis of a process vessel when a 16electrode sensing ring is employed. The paper also reports the use of a guarded electrode scheme can reduce the imaging displacement but has no evident effects at the compressing the sensing space.
