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

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Alexander Scharf; [2019]
    Keywords : laser scanning; facade monitoring; point cloud; wooden facade;

    Abstract : 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. READ MORE

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

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

    Author : Meng Li; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Adaptive Backprojection : Developing a simple reconstruction algorithm

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Ante Vernersson; [2018]
    Keywords : CT; Computed Tomography; Backprojection; Reconstruction; 3D; Adaptive Backprojection; Algorithm;

    Abstract : This group project aims to investigate the possibility ofconstructing a prototype micro-CT-scanner, hopefullyfurthering the advancement in the field of small CT-scanners,with the ultimate goal to provide a structure useable in anambulance, to scan and send images to the hospital, so thattreatment can commence directly upon arrival.This report deals with the matter of reconstructing the takenimages to construct a three-dimensional model of thescanned object.
