Hybrid Computing for Solving Inverse Problem of Electrical Impedance Tomography

抄録

This paper presents hybrid computing approach to solve inverse problem. An application in Electrical Impedance Tomography (EIT) with Newton's method is employed to introduce the new approach. With hybrid computing approach, accurate Jacobian matrix in Newton iteration can be obtained through derivative operation on explicit expressions between a particular response and a set of system parameters in EIT, which is impossible to be achieved by conventional numerical computing approach. Comparing with symbolic computing and general hybrid computing, limited variables are kept symbolic in order to decrease computing complexity. The simulation results have illustrated that the hybrid computing approach proposed in this paper is valid for solving inverse problem of Electrical Impedance Tomography.
