Computing of the Forward and Inverse Solutions of Electrical Impedance Tomography Using a 32-bit Microcontroller System

Abstract

The forward and inverse solution of the Electrical Impedance Tomography (EIT) governing equation (Laplace's and Poisson's equation) have been analyzed and implemented in personal computers and small board computers but not in computers based on microcontrollers. In this work, both solutions, the forward and inverse problem were computed and implemented into an embedded system based on 32-bit microcontrollers with practical applications as portable tomographic systems avoiding the use of a PC and reducing the size of the tomographic systems, this means that it is not required a PC to compute the forward or inverse solution in EIT.
