Approximate 3-Dimensional Electrical Impedance Imaging

We discuss a new approach to three-dimensional electrical impedance imaging based on a reduction of the information to be demanded from a reconstruction algorithm. Images are obtained from a single measurement by suitably simplifying the geometry of the measuring chamber and by restricting the nature of the object to be imaged and the information required from the image. In particular we seek t...

Four-Dimensional Regularization for Electrical Impedance Tomography Imaging

This paper proposes 4-D EIT image reconstruction for functional EIT measurements. The approach directly accounts for 3-D interslice spatial correlations and temporal correlations between images in successive data frames. Image reconstruction is posed in terms of an augmented image x̃ and measurement vector ỹ, which concatenate the values from the d previous and future frames. Image reconstructio...

Three- dimensional Effects in Electrical Impedance Tomography

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 whe...
