    • 3D orientational imaging of gallbladder stones 

      Ruiz Martínez, Alejandro (Bachelor thesis, 2024)
      X-ray Diffraction Tensor Tomography is an emerging imaging technique to study the mineralogy and orientation of crystallites at a microscale level. In the work presented in this thesis, we have tested an algorithm developed ...

    • Generative Adversarial Networks in X-ray Computed Tomography 

      Urdahl, Trygve Scheline (Master thesis, 2021)
      Computertomografi (CT) med røntgenstråler åpner opp for ikke-destruktiv bildetaking av interne strukturer i materialer. Prosessen for å ta CT-bilder består av å måle røntgenprojeksjoner av en prøve, for deretter å ...

    • Insight from electron density and energy framework analysis on the structural features of Fx-TCNQ (x= 0, 2, 4) family of molecules 

      Shukla, Rahul; Ruzié, Christian; Schweicher, Guillaume; Kennedy, Alan R; Geerts, Yves H.; Chopra, Deepak; Chattopadhyay, Basab (Journal article; Peer reviewed, 2019)
      In this study, the nature and characteristics of the intramolecular and intermolecular interactions in crystal structures of the fluoro-substituted 7,7,8,8-tetra­cyano­quinodi­methane (TCNQ) family of molecules, i.e. Fx-TCNQ ...

    • Multiscale X-ray tomography for shale microstructure and mechanical behaviour 

      Madathiparambil, Aldritt Scaria (Doctoral theses at NTNU;2024:39, Doctoral thesis, 2024)
      Studying shales and other sedimentary rock systems is important to provide a fundamental understanding of their microstructural properties, including the mechanical response and the permeability of liquids and gases. ...

    • Nanoscale imaging of shale fragments with coherent X-ray diffraction 

      Chattopadhyay, Basab; Madathiparambil, Aldritt Scaria; Mürer, Fredrik Kristoffer; Cerasi, Pierre; Chushkin, Yuriy; Zontone, Federico; Gibaud, Alain; Breiby, Dag Werner (Journal article; Peer reviewed, 2020)
      Despite the abundance of shales in the Earth’s crust and their industrial and environmental importance, their microscale physical properties are poorly understood, owing to the presence of many structurally related mineral ...

    • Orientational mapping of minerals in Pierre shale using X-ray diffraction tensor tomography 

      Mürer, Fredrik Kristoffer; Madathiparambil, Aldritt Scaria; Tekseth, Kim Robert Bjørk; Di Michiel, Marco; Cerasi, Pierre; Chattopadhyay, Basab; Breiby, Dag Werner (Peer reviewed; Journal article, 2021)
      Shales have a complex mineralogy with structural features spanning several length scales, making them notoriously difficult to fully understand. Conventional attenuation-based X-ray computed tomography (CT) measures density ...

    • Quantifying the hydroxyapatite orientation near the ossification front in a piglet femoral condyle using X-ray diffraction tensor tomography 

      Mürer, Fredrik Kristoffer; Chattopadhyay, Basab; Madathiparambil, Aldritt Scaria; Tekseth, Kim Robert Bjørk; Di Michel, Marco; Liebi, Marianne; Lilledahl, Magnus Borstad; Olstad, Kristin; Breiby, Dag Werner (Peer reviewed; Journal article, 2021)
      While a detailed knowledge of the hierarchical structure and morphology of the extracellular matrix is considered crucial for understanding the physiological and mechanical properties of bone and cartilage, the orientation ...

    • The Effects of Wide-Angle Scattering on Coherent Diffraction Imaging 

      Stene, Sigurd (Master thesis, 2023)
      De potensielle negative effektene av vidvinkel-spredning på fasegjenvinningsprosessen i koherent røntgendiffraksjonsavbildning (CDI) har blitt undersøkt ved bruk av numeriske beregninger. CDI er avbildningsmetode som kan ...
