Design of a Low-Cost Acquisition System to Reconstruct Images through Electrical Resistance Tomography
Keywords:Image analysis, Computerized Tomography, low cost acquisition system
Electrical Resistance Tomography (ERT) is a technique employed in industrial environment that reconstructs images formed by the impedance distributions inside a vessel.
The method relies on measures from a data acquisition system, responsible to inject a current inside the vessel and measures the voltage on the boundaries, and sequentially an inverse problem
solution. This paper introduces a low-cost design of an acquisition system that can obtain 30 images/s, utilizing simple methods to provide a good accessibility to researchers aimed in investigating
flow patterns of multiphase flow applications.
