Fast Small‐Angle X‐Ray Scattering Tensor Tomography: An Outlook into Future Applications in Life Sciences

Small Methods, Volume 10, Issue 1, 10 January 2026.
This study reveals the future potential of SAXS tensor tomography at macromolecular X‐ray crystallography beamlines and life sciences applications. A new standard in fast data acquisition is set, allowing for up‐to 10x higher throughput. The measurements show mineralised collagen fibrils within the incus bone of the human auditory ossicle.
