Total variation minimization approach in in-line x-ray phase-contrast tomography
TL;DR: This work investigates how this system can be solved using three different algebraic reconstruction algorithms based on Total Variation minimization and demonstrates that algebraic algorithms may become an important tool in applications where the acquisition time and the delivered radiation dose must be minimized.
Journal ArticleDOI
Phase retrieval in in-line x-ray phase contrast imaging based on total variation minimization
TL;DR: The presented method was shown to deliver improved accuracy in reconstructions based on a single distance as well as multiple distance phase-contrast images corrupted by noise and hampered by errors due to nonlinear imaging effects.
Journal ArticleDOI
Integrating expert feedback on the spot in a time-efficient explorative CT scanning workflow for cultural heritage objects
Francien G. Bossema,Francien G. Bossema,Sophia Bethany Coban,Alexander Kostenko,Paul van Duin,Jan Dorscheid,Isabelle Garachon,Erma Hermens,Erma Hermens,Robert van Liere,Robert van Liere,K. Joost Batenburg +11 more
TL;DR: This paper shows how a time-efficient explorative workflow can be created for CT investigation of art objects, where the object can be inspected in 3D while still in the scanner, and based on the observations and the resulting new questions, the scanning procedure can be iteratively refined.
Journal ArticleDOI
Dating and provenancing the Woman with lantern sculpture – A contribution towards attribution of Netherlandish art
Marta Domínguez-Delmás,Marta Domínguez-Delmás,Francien G. Bossema,Francien G. Bossema,Bieke van der Mark,Alexander Kostenko,Sophia Bethany Coban,Sjoerd van Daalen,Paul van Duin,K. Joost Batenburg +9 more
TL;DR: In this paper, the Woman with lantern was found to date to 1487 C.E. and the outermost ring was estimated to have been cut after 1495 C. E., indicating a likely production in the first quarter of the 16th century.
Journal ArticleDOI
Prototyping X-ray tomographic reconstruction pipelines with FleXbox
Alexander Kostenko,Willem Jan Palenstijn,Sophia Bethany Coban,Allard A. Hendriksen,R. van Liere,Kees Joost Batenburg,Kees Joost Batenburg +6 more
TL;DR: The modular architecture of FleXbox allows to design an optimal reconstruction approach for a single CT dataset, which allows to create a computational reconstruction pipeline that can run without user interaction and enables efficient computation on large-scale 3D volumes on a single workstation.
