1. A method for performing automatic analysis of cross-sections of micro-channels, the method comprising:
receiving tomography scan data;
aligning the tomography scan data;
extracting channels from a slice of the tomography scan data to create an isolated slice of the extracted channels;
determining surface voxels for the extracted channels;
determining an area defined within the surface voxels for each of the extracted channels;
determining a contribution of the surface voxels for each of the extracted channels to the cross-section of the extracted channels, wherein determining the contribution of the surface voxels to the cross-section of the extracted channels comprises weighting each surface voxel based on its gray value and summing over all surface voxels for the cross-section of the extracted channels; and
outputting cross-section information based on the contribution of the surface voxels.
