  bibo_abstract:
  - <jats:p>In-situ computed tomography (CT) experiments on materials with time-dependent
    mechanical behaviour are affected by relaxationinduced motion, which can lead
    to image blur and motion-related artefacts if scans are initiated before relaxation-induced
    motion has subsided. Scan start times are therefore commonly defined based on
    force relaxation or force-gradient criteria, although these signals do not directly
    quantify image-relevant specimen motion. In this work, a radiography-based approach
    is presented to estimate relaxation-induced motion via pixel shifts from projection
    images acquired prior to CT scans. These projection-based pixel shift estimates
    of relaxation-induced motion are related to scan-specific image blur observed
    in the reconstructed volumes. Thereby, a direct link between specimen motion during
    the scan and CT image quality is established. The method is demonstrated for thermo-mechanically
    loaded specimens with pronounced temperature-dependent material behaviour, where
    relaxation-induced motion persists over extended time scales. The results show
    that projection-based pixel shift estimation provides a physically meaningful
    and experimentally accessible basis for defining scan start criteria. CT acquisition
    can be initiated based on an allowable level of relaxation-induced motion, rather
    than waiting for mechanical equilibrium to be reached. The proposed approach therefore
    offers a direct, image-related framework for scan timing in in-situ CT experiments
    on time-dependent materials.</jats:p>@eng
