  1. 1. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling

    Master-uppsats, KTH/Fysik

    Författare :Johanna Jacobsson; [2022]
    Nyckelord :computed tomography; magnetic resonance imaging; cone beam computedtomography; cartilage; osteochondral lesions; metatarsal phalangeal joint; datortomografi; magnetisk resonanstomografi; kon-datortomografi; brosk; kondrala skador; metatarsalphalangen-leden;

    Sammanfattning : Walking without pain in the toe has a significant impact on a person’s well-being. Human mobility will be impaired in osteoarthritis of the big toe, and pain will occur during walking. By replacing the cartilage or bone injury with an individualised implant, osteochondral injuries to the knee and ankle can be treated. LÄS MER

  3. 2. Benchmarking of computational methods for Spatial Transcriptomics Data analysis

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Nima Taherpour; [2022]
    Nyckelord :Spatial Transcriptomics; Scanpy; Squidpy; Giotto; Seurat;

    Sammanfattning : Ökningen av sekvenseringsdata har skapat ett behov av att ta fram nya och flexibla analysmetoder för att kunna analysera datan. Många sekvenseringsteknologier har utvecklats genom åren, med olika syften och de är idag mer specialiserade. LÄS MER

  4. 3. Improved Spatial Resolution in Segmented Silicon Strip Detectors

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Eva Bergström; Ida Johansson; [2019]
    Nyckelord :computed tomography; photon-counting; silicon strip detector; spatial resolution; machine learning; classification; datortomografi; fotonräknande; kiselstrippdetektor; spatiell upplösning; maskininlärning; klassificering;

    Sammanfattning : Semiconductor detectors are attracting interest for use in photon-counting spectral computed tomography. In order to obtain a high spatial resolution, it is of interest to find the photon interaction position. LÄS MER

  5. 4. Noise modelling for high-throughput super-resolution microscopy

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xavier Casas Moreno; [2018]
    Nyckelord :;

    Sammanfattning : Super-resolution fluorescence microscopy is an emerging imaging fieldthat aims at breaking the di↵raction barrier of light based on state transitionin fluorescent molecules. Current challenges in the existing approachare to achieve large field of views, fast recordings and increasing the imagequality. LÄS MER

  7. 5. Development of 3D Spectrometry using Compressive Sensing

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

    Författare :Jonas Ravelid; [2018]
    Nyckelord :Compressive Sensing; 3D; Spectroscopy; Imaging; Multi-spectral; CS; TwIST; Mask; Physics and Astronomy;

    Sammanfattning : Multi-spectral imaging is a powerful approach in spectral analysis of objects with spatial details. However, such approaches are most often time consuming and experimentally complex since both spectral and spatial information in two dimensions are to be resolved. LÄS MER
