Repository content

The repository is organized as follows.

• Folder 2D: two-dimensional ODT [1]
  • In folder code, the script main_fig7.m reproduces Figure 7 of [1].
  • The folder mat_files contains data.
• Folder 3D: three-dimensional ODT [2]
  • The script DiscretizationGreen.m reproduces Figure 3 of [2],
  • (coming soon) The script ExampleFwdModel.m provides an example on how to use the iterative Lippmann-Schwinger forward model,
  • (coming soon) The script Compute_uin.m reproduces Figure 5 of [2],
  • (coming soon) The script ODT_Reconstruction.m contains the whole reconstruction pipeline.
