[0025] Explanation of terms involved in the present invention:
[0026] Electrical Impedance Tomography (EIT) is an electromagnetic imaging technique that reconstructs the distribution or change of electrical impedance by applying a certain safe excitation current to the measured object and measuring the voltage signal on its surface.
[0027] The finite element method (Finite Element Method, FEM) is a method based on the variational principle to solve nonlinear equations by finding extreme values of functional functions. The specific method is to find out the corresponding functional and its variational problem corresponding to the boundary value problem; divide the field reasonably, and use the shape function in the subdivided unit and the discrete point on the unknown function of any point in the unit The value of the function is expanded; the extreme value of the functional is obtained, and the simultaneous algebraic equations are derived, which are called finite element...
