  1. 1. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Erika Ax; Elin Djerf; [2023]
    Nyckelord :mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder; 3D; classification; reconstruction; artefacts;

    Sammanfattning : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. LÄS MER

  3. 2. Faster Environment Modelling and Integration into Virtual Reality Simulations

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Jonas Nyman; [2021]
    Nyckelord :3D re-construction; Digital Photogrammetry; LiDAR; Remote Sensing; Point Cloud; Point cloud to mesh; Terrestrial Laser Scanning; Static Laser scan; Virtual Reality;

    Sammanfattning : The use of virtual reality in engineering tasks, such as in virtual commissioning, has increased steadily in recent years, where a robot, machine or object of interest can be simulated and visualized. Yet, for a more immerse experience, an environment for the object in question needs to be constructed. LÄS MER

  4. 3. Reverse Engineering med hjälp av 3D-skanning

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Sammanfattning : Inom området maskinteknik finns idag ett stort intresse för Reverse Engineering med hjälp av 3Dskanning. Tekniken utgår ifrån att skapa Computer-Aided-Design (CAD) modeller av reala objekt. LÄS MER

  5. 4. Terrestrial Laser Scanning for Wooden Facade-system Inspection

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Alexander Scharf; [2019]
    Nyckelord :laser scanning; facade monitoring; point cloud; wooden facade;

    Sammanfattning : The objective of this study was to evaluate the feasibility of measuring movement, deformation and displacement in wooden façade-systems by terrestrial laser scanning. An overview of different surveying techniques and methods has been created. LÄS MER

  7. 5. Developing a technique for combining light and ultrasound for deep tissue imaging

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

    Författare :Meng Li; [2018]
    Nyckelord :UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Sammanfattning : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. LÄS MER
