Fig. 3: Missing wedge of information degrades chemical tomography.
From: Optimal 3D chemical imaging with multimodal electron tomography
a 2D tilt range illustration of missing wedge regions (pink). b Tilt range versus NRMSE plot charting how traditional chemical tomography (red line with diamonds), and chemical tomography with total variation (green line with circles) always result in greater error compared to MM-ET (blue line with squares) at a given missing wedge size. c 2D XY slices of 3D reconstructed volume for various missing wedge sizes on synthetic CoO/CuO nanocube dataset. Elongation along one direction grows as missing wedge size increases. CuO appears yellow, CoO appears red. Tilt range is labeled for each 2D slice.
