Researchers have developed a new unsupervised deep learning method, DIP-TV, to improve 3D chemical analysis in STEM-EDX tomography. This technique addresses limitations caused by restricted tilt ranges and low-dose imaging, which typically lead to missing-wedge artifacts and degraded reconstruction quality. The enhanced multi-channel version, DIPm-TV, reconstructs multiple elemental maps simultaneously by leveraging spatial correlations, outperforming existing methods in compensating for severe angular limitations and noise.
