# Electrical Impedance Tomography

This web app takes as input an image representing an electrically conductive medium. \

It solves for the voltage and current at every point of the medium, when two nodes are selected as the voltage source and the ground. \

For now, only the resistive nature of the medium is considered. (static domain simulations) 

## Usage

First, select the image you want to simulate. The image should be a black and white image, where black represents regions of high resistance and white represents regions of low resistance. \

You can use the image provided in the repository, or upload your own. \

The successively process the image (this converts the PNG to a pixel intensity matrix) \

Then, convert this pixel matrix into its electrical circuit representation. \

Finally, click solve and wait for the results. 

## Future features

-~~GPU Implementation of circuit solving~~ Already 15x speedup with fmgpu for 32x32 which now takes 1s to process, but 64x64 still takes 60s \

-Go through every ground/source node setting, animate the results \

-Use simulation results to attempt to reconstruct the original image \

-Future versions will simulate capacitive/reactive effects of the sliced medium. Time domain results will be shown
