Resolution enhancement in micro-XRF using image restoration techniques
Journal of Analytical Atomic Spectrometry, 2022 Micro X-ray fluorescence analysis commonly (micro-XRF) has a lower spatial (lateral) resolution than other elemental mapping techniques like scanning electron microscopy. This disadvantage limits further applications of micro-XRF.
