Effiziente Berechnung räumlicher Diskretisierungen für 3D Elektrische Impedanztomographie

Efficient Meshing for 3D Electrical Impedance Tomography

Task Description / Aufgabenstellung

General Setting

Electrical Impedance Tomography is an imaging technique based where one induces a current into a medium and measures voltages through electrodes to reconstruct the impedance distribution in the medium in order to reconstruct the underlying material properties. At iMEK we are researching on how to advance this technology to come up with accurate results in real time. In order to develop a sophisticated system we require a discretization of the measurement cell to in order to to be able to reconstruct the conductivity inside the cell. In our experiments we found out that the computational complexity of such a discretization (which we refer to as a mesh) largely varies between different meshing tools. This work should tackle the question why the complexity varies.

Task Description / Aufgabenstellung

In this work the student is responsible to evaluate different Meshing options for EIT reconstruction. The work can be structured in the following substeps:

1. Define Evaluation Criteria: Alongside with the time to create a mesh, different criteria might be of interest to qualify what a “good” mesh for our purpose is.

2. Introduction of state of the art algorithms. What are the most common implementations and why should one (not) choose which option.

3. Evaluation of existing tools. Which tools are out there? Which algorithms do they use to mesh the domain?

4. Testing: How good do the tools work for our specific purpose?

5. Recommendation: Which tool should we use at iMEK for meshing in the context of Electrical Impedance Tomography?

General Information:

We are currently implementing a Python suite to automate evaluations for electrical Impedance Tomography. Therefore it is mandatory for the solution to integrate seamlessly with the existing software.
