The EIDORS software simplifies electrical impedance and diffuse optical tomography research through a redesigned structure. It aims to reduce numerical errors in inverse problems by promoting code sharing and documenting potential pitfalls.

Area of Science:

  • Computational imaging
  • Biomedical engineering
  • Inverse problems

Background:

  • Electrical impedance tomography (EIT) and diffuse optical tomography (DOT) are crucial for medical imaging.
  • Open-source software facilitates research and collaboration in these complex fields.
  • Existing software structures can hinder usability and customization.

Purpose of the Study:

  • To describe the redesigned software structure of EIDORS.
  • To simplify the use and customization of EIDORS for EIT and DOT.
  • To address the challenge of numerical errors in inverse problem software.

Main Methods:

  • Redesigning the EIDORS software architecture for a uniform interface.
  • Documenting key software features and providing usage examples.
