  1. 1. Bilddiagnostik av barn ochungdomar vid skolios : En jämförande litteraturstudie mellan konventionell röntgen, datortomografi och entrepreneurial operating system

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Ida Söderberg; Van Najm; [2023]
    Nyckelord :Computed tomography; conventional radiography; entrepreneurial operating system; image diagnostics; radiation dose; Bilddiagnostik; datortomografi; entrepreneurial operating system; konventionell röntgen; stråldos;

    Sammanfattning : Bakgrund: Konventionell röntgen, datortomografi (DT) och entrepreneurial operating system (EOS) är tre radiologiska undersökningsmetoder som kan användas för bilddiagnostik vid skolios av barn och ungdomar. Undersökningarna kan genomföras i en liggande eller stående positionering vid bedömning av ryggradens deformation. LÄS MER

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

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER

  4. 3. Fine-Tuning Parameters in CT

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

    Författare :Anton Adelöw; Tomas Nordström; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Ruben Hedström; [2023]
    Nyckelord :gamification; medicine; computed tomography; programming;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Väg- och banteknik

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

    Sammanfattning : 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.
