New method improves XRF map localization in optical microscopy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for localizing X-ray fluorescence (XRF) maps within optical microscopy images, addressing the challenge of aligning data from two modalities with different contrast mechanisms and resolutions. The proposed technique formalizes XRF tile-group localization, where a single placement in the optical frame is estimated for an entire group of XRF tiles, utilizing acquisition geometry as a constraint. This approach significantly improves localization accuracy, achieving a GroupIoU of 0.931 in a controlled study compared to 0.000 for independent tile placement. Further enhancements were observed in multiscale studies, where using a coarse XRF survey scan increased mean GroupIoU from 0.694 to 0.856. AI

IMPACT This research offers improved methods for integrating data from different imaging modalities, potentially enhancing scientific analysis in fields utilizing XRF and optical microscopy.

    Acquisition Geometry-Assisted Whole-Group Localization of X-ray Fluorescence Maps in Optical Microscopy Images

    arXiv:2608.18305v1 Announce Type: new Abstract: X-ray fluorescence (XRF) microscopy maps elemental distributions, while optical microscopy can provide complementary morphological context. Localizing XRF fields of view (FOVs) in optical images is difficult because the two modaliti…
