  1. 1. Quality enhancement of time-resolved computed tomography scans with cycleGAN

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

    Author : Johannes Stubbe; [2023]
    Keywords : carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

    Abstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE

  3. 2. Fine-Tuning Parameters in CT

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Anton Adelöw; Tomas Nordström; [2023]
    Keywords : ;

    Abstract : Computed tomography (CT) is a medical imaging technique that usesX-rays to obtain a reconstruction of an object. The term acquisition ge-ometry refers to the arrangement of imaging sensors and the X-ray sourceas well as the procedure used for data collection. READ MORE

  4. 3. Development of application for game-like reinforcement of tomographic image interpretation skills

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Ruben Hedström; [2023]
    Keywords : gamification; medicine; computed tomography; programming;

    Abstract : Learning to identify anomalies in x-ray images is a time consuming and difficult task. Manyhours of looking at similar images to familiarize oneself with the images can feel daunting andunmotivating. This is why a game application where the user, in a challenging environment, canlearn while being adequately stimulated. READ MORE

  5. 4. Assessment of aggregate structure in porous asphalt using X-ray computed tomography

    University essay from KTH/Väg- och banteknik

    Author : Mari Haagenrud Matsson; Malex Love Valdemar Åkerblom; [2023]
    Keywords : Tomography; non-destructive testing; destructive testing; air voids content; aggregate size distribution; porous asphalt;

    Abstract : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.

  6. 5. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Falk; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE
