  1. 11. Development of a CNC Milling System for Preparation of Micrometer-Sized Samples for X-ray Nanotomography

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Olivia Messler; [2021]
    Nyckelord :Nanotomography; Sample Preparation; CNC; Nanotomografi; Provpreparering; CNC;

    Sammanfattning : X-­ray nanotomography is an imaging technique used to study three­-dimensional structures at submicrometer length scale. The samples to be studied should be only 10s of micrometers in diameter, and ideally cylindrical. LÄS MER

  3. 12. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields

    Kandidat-uppsats, Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysik

    Författare :Adi Bijedic; [2021]
    Nyckelord :;

    Sammanfattning : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. LÄS MER

  4. 13. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  5. 14. Quantification of Fetal Volume in Magnetic Resonance Images Using Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Amanda Nilsson; [2021]
    Nyckelord :MRI; Deep Learning; U-Net; Semantic segmentation; Fetal body volume; fetal MRI; Segmentation; Magnetic Resonance Imaging; Mathematics and Statistics;

    Sammanfattning : Background: Fetal Magnetic Resonance Imaging is an imaging technique that visualizes the fetus during pregnancy. It is used for assessing and diagnosing disease, for monitoring high risk pregnancies, and for conducting research. LÄS MER

  7. 15. Deep-learning image reconstruction for photon-counting spectral computed tomography

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Viggo Moro; [2021]
    Nyckelord :;

    Sammanfattning : X-ray computed tomography (CT) has since its introduction in the early 1970s become one of the most important tools used for medical imaging. In CT, a large number of x-ray attenuation measurements are combined and reconstructed to form a three-dimensional image of the targeted area. LÄS MER
