  1. 1. Beyond Traditional Tomography: X-ray Multi-projection Imaging for Additive Manufacturing

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Maria Esther Vilar Alvarez; [2023]
    Keywords : X-ray tomography; X-ray multiprojection-imaging; deep learning; additive manufacturing; synchrotron radiation; Physics and Astronomy;

    Abstract : The main aim of this bachelor thesis is to push the limits of 3D X-ray imaging by studying the minimum number of projections required to retrieve high-quality reconstructions for additive manufacturing processes. This project first focuses on understanding how X-ray tomography works, by reconstructing additive manufacturing data already obtained (from PSI, TOMCAT beamline) using two standard reconstruction algorithms, GRIDREC and SIRT.

  3. 2. Development and Evaluation of a Tomographic Technique for Volumetric Imaging of Flames

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : David Sanned; [2018]
    Keywords : 3D-Tomography; Additive Reconstruction Technique; Space Carving; Machine Vision Cameras; Imaging of Flame Models; Technology and Engineering; Physics and Astronomy;

    Abstract : With modern day interest to continue the reduction of harmful emissions and improve the efficiency of combustion devices, the need to further improve upon accuracy and ability to describe combustive processes is of high value. Nowadays, multiple capable point (0D) and two-dimensional measurement (2D) techniques exist for flame investigation, however as combustion nearly always is a three-dimensional (3D) process some limitations do exist within many of these techniques.

  4. 3. Influence of Sample Preparation on Portable XRF-analyses of Aeolian Sediments: a Case Study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Markus L. Fiola; [2017]
    Keywords : portable XRF; loess; sediment; bärbar XRF; lössjord; sediment;

    Abstract : The geochemical composition of aeolian sediments like windblown dust particles is of major importance for the exploration of dust origin and weathering conditions. This allows for the reconstruction of dust transport pathways and thus wind directions and palaeoclimate conditions. READ MORE

  5. 4. Investigation of Algebraic Reconstruction Techniques for Tomographic Measurements on Spent Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Institutionen för strålningsvetenskap

    Author : Tobias Lundqvist; [2004]
    Keywords : ;

    Abstract : A non-destructive tomographic measurement technique for application on nuclear fuel assemblies has beendeveloped at the Uppsala University. Using this technique, the rod-by-rod distribution of selectedradioactive isotopes is determined experimentally. READ MORE
