A Nodal Jacobian Inverse Solver for Reduced Complexity Eit Reconstructions

  title={A Nodal Jacobian Inverse Solver for Reduced Complexity Eit Reconstructions},
  author={Brad M. Graham and Andy Adler},
Electrical impedance tomography (EIT) uses surface electrodes to make measurements from which an image of the conductivity distribution within some medium is calculated. Calculation of conductivity solutions requires inverting large linear systems that have to date restricted reconstructions to 2D or coarse 3D domains. This paper presents a Nodal Jacobian Inverse Solver that scales with the number of nodes in a finite element mesh rather than with the number of elements. For the example used in… CONTINUE READING
