Electrical Impedance Tomography Image Reconstruction

Independent Study using Variational Autoencoders

Electrical Impedance Tomography Image Reconstruction

Duration: August 2023 – January 2024
Type: Independent Study

This project explored the application of variational autoencoders (VAEs) to tackle the ill-posed inverse problem in Electrical Impedance Tomography (EIT) image reconstruction. The primary goal was to achieve a 5% improvement in image quality compared to state-of-the-art models.

Key Achievements:

  • Implemented novel VAE architectures specifically designed for EIT reconstruction
  • Developed advanced regularization techniques to handle the ill-posed nature of the problem
  • Achieved improved reconstruction quality through learned latent representations
  • Compared performance against existing reconstruction methods

Technical Details:

EIT is a medical imaging technique that reconstructs the internal conductivity distribution of an object from electrical measurements taken at its boundary. The main challenge lies in the ill-posed nature of the inverse problem, where small measurement errors can lead to significant reconstruction artifacts.

Our approach leveraged the power of variational autoencoders to learn meaningful representations of conductivity distributions, enabling more robust and accurate reconstructions even in the presence of measurement noise.

Technologies Used:

  • Python
  • TensorFlow/PyTorch
  • MATLAB
  • Advanced optimization algorithms
  • Medical imaging processing tools img: /assets/img/12.jpg —
Caption photos easily. On the left, a road goes through a tunnel. Middle, leaves artistically fall in a hipster photoshoot. Right, in another hipster photoshoot, a lumberjack grasps a handful of pine needles.
This image can also have a caption. It's like magic.

You can also put regular text between your rows of images, even citations (missing reference). Say you wanted to write a bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

You can also have artistically styled 2/3 + 1/3 images, like these.

The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

<div class="row justify-content-sm-center">
  <div class="col-sm-8 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/6.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
  <div class="col-sm-4 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/11.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
</div>
