This study introduces novel planar electrical impedance tomography (EIT) for medical imaging when only one patient side is accessible. It presents two reconstruction methods: one quantitative and one qualitative for anomaly detection.

Area of Science:

  • Medical Imaging
  • Electrical Impedance Tomography
  • Biomedical Engineering

Background:

  • Traditional medical imaging often requires access to multiple sides of a patient.
  • Noninvasive imaging techniques are crucial for patient comfort and safety.
  • Electrical Impedance Tomography (EIT) offers a promising noninvasive imaging modality.

Purpose of the Study:

  • To present numerical results for two reconstruction methods for a new planar EIT device.
  • To enable noninvasive medical imaging when only one side of a patient is accessible.
  • To evaluate the performance of quantitative and qualitative reconstruction methods for EIT.

Main Methods:

  • Development of a new planar electrical impedance tomography device.
  • Implementation and numerical evaluation of a linearization-type reconstruction method.

Related Experiment Videos

  • Implementation and numerical evaluation of a factorization-type reconstruction method.

    • Main Results:

    • The linearization-type method provides quantitative reconstructions.
    • The factorization method offers qualitative reconstructions for anomaly detection.
    • Both methods are evaluated for a planar EIT setup with unilateral access.

    Conclusions:

    • The new planar EIT device with unilateral access is feasible for medical imaging.
    • The developed reconstruction methods offer complementary capabilities for EIT applications.
    • Quantitative and qualitative EIT reconstructions can be achieved with the presented approaches.
