Insulin reconstruction and segmentation. From top row to bottom: the result of iterative reconstruction using the ToMoBAR package, manual segmentation using Avizo, a complete GeoDistance thresholding segmentation for all phases, RegionGrow segmentation using an input from GeoDistance to segment the crystal. One can see that the GeoDistance method provides a reasonably good segmentation for all phases. RegionGrow adds a small improvement to the existing GeoDistance segmentation for the crystal.
