Induced current electrical impedance tomography (EIT) reconstructs conductivity using magnetic fields and surface voltage. While less sensitive to interior changes than injected current EIT, it offers comparable image resolution and a better-conditioned sensitivity matrix.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Computational Electromagnetics

Background:

  • Electrical Impedance Tomography (EIT) aims to map internal conductivity distributions.
  • Induced current EIT utilizes time-varying magnetic fields to induce currents for imaging.
  • Reconstructing conductivity is crucial for diagnosing various physiological conditions.

Purpose of the Study:

  • Investigate the mathematical basis of induced current EIT.
  • Analyze the two-dimensional problem for conductivity reconstruction.
  • Evaluate the performance and limitations of induced current EIT.

Main Methods:

  • Derived the partial differential equation for the scalar potential in a conductive medium.
  • Applied the finite element method (FEM) for solving the governing equation.

  • Calculated the sensitivity matrix using a 9-coil system and 16 electrodes.

    • Main Results:

    • Determined 135 independent measurements via singular value decomposition of the sensitivity matrix.
    • Observed reduced sensitivity to interior conductivity changes compared to injected current EIT.
    • Achieved image resolution comparable to injected current EIT.

    Conclusions:

    • Induced current EIT is a viable imaging modality with a well-conditioned sensitivity matrix.
    • Further coil system design is needed to optimize sensitivity to inner regions.
    • The technique shows promise for non-invasive conductivity mapping.
