New method improves XRF map localization in optical microscopy

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

    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…
