Electrical Impedance Tomography (eit) Method for Saturation Determination

3D Electrical Impedance Tomography (EIT) is an alternative to the traditional CT scan technique that has been used to measure saturation distribution within a rock core. The primary motivation for investigating EIT is the applicability to high pressure, high temperature geothermal reservoir conditions, which would require a metal core holder, therefore eliminating the use of the CT scan techniq...

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...

Implementation of Radon Transformation for Electrical Impedance Tomography (EIT)

Radon Transformation is generally used to construct optical image (like CT image) from the projection data in biomedical imaging. In this paper, the concept of Radon Transformation is implemented to reconstruct Electrical Impedance Topographic Image (conductivity or resistivity distribution) of a circular subject. A parallel resistance model of a subject is proposed for Electrical Impedance Top...

An Current Source Using a Negative Impedance Converter (nic) for Electrical Impedance Tomography (eit)

The purpose of this paper is to improve the output impedance of a current source used for Electrical Impedance Tomography (EIT) by using a Negative Impedance Converter (NIC). A Monopolar Howland Current Source(MHCS) and NIC circuits were implemented and then the output impedance was measured by a Data Acquisition (DAC) board of 12 bits resolution. A resistive load was used for investigating the...
