Estimating/Calculating volume using pyEIT #108

Hi, maybe you should investigate 3D eit, where electrodes are placed in a multi-layer fasion. PyEIT had a 3D EIT reconstruction feature days ago, where it uses VTK and mayavi to illustrate the reconstruction results using a ball. These codes are removed (maybe I can find the related commits). 3D reconstruction and 2D are alike, where jac is simply computed in 3D tetrahedrons. |

Hello,
I have been exploring pyEIT and am now interested in estimating the volume of an object.
In an experiment, I slowly submerged a bottle into a basin filled with water. I observed that the reconstructed EIT image gradually changed color in the area which is taking place by the object as it was lowered. I realized that, although EIT provides a single slice reconstructed image, it actually calculates the average impedance across the entire volume. The current distribution spreads throughout the solution, influencing the overall impedance measurement.
I wonder whether pyEIT has built-in features or possible methods to estimate the volume of an object solely based on EIT data. My ultimate goal is to measure the volume of air pumped into a latex balloon submerged in water - without using any additional air sensors, relying only on pyEIT.
Could you point me to any relevant documentation or resources that might help with this?
Thank you!
