Fig. 6: The signal-to-noise ratios of elastic and inelastic modalities affect reconstruction quality.

From: Optimal 3D chemical imaging with multimodal electron tomography

Fig. 6

a Average reconstruction error across SNR of each modality (elastic or inelastic) when 11 chemical maps (Δθ = 14∘) and 141 elastic (HAADF) projections (Δθ = 1∘) are available. b Synthetic CoNiO nanotube ground truth in 3D (rendered in Tomviz, scalebar 50 nm). c Three combinations of SNR levels: low inelastic and high elastic SNR, high inelastic and low elastic SNR, high inelastic and elastic SNR. Higher SNR in both modalities improves quality; however, experimentally it is desirable to prioritize the SNR of the lower-fluence modality.
