Dynamic imaging in electric capacitance <a href="https://en.wikipedia.org/wiki/tomography" class="extiw" title="w:tomography">tomography</a>.
<dl><dd>On the left, an animation showing seven cylindrical objects moving along the probe. On the right, a series of probe cross-sectional images reconstructed by the linear back projection method from consecutive capacity measurements. The color represents the relative permeability <i> ε </i> at a given point in space. Image created using Blender and Matlab software</dd></dl>
