  1. 1. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Yoseph Abraham; [2023]
    Nyckelord :;

    Sammanfattning : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). LÄS MER

  3. 2. Mechanical Properties of Calcium Phosphate and Additively Manufactured Titanium Alloy for Composite Spinal Implants

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Josephine Lantz; [2021]
    Nyckelord :calcium phosphate; titanium; spinal implant; tensile testing; compression tests; 4-point-bending; finite element analysis; topology optimisation;

    Sammanfattning : One of the major health problems in western societies is back pain, with a prevalence rate of 49%–80%. In many cases, the back pain is due to degenerated discs. The gold standard to treat a severely degenerated disc is spinal fusion, where the vertebral disc is replaced with a cage structure. LÄS MER

  4. 3. Deep Learning for PET Imaging : From Denoising to Learned Primal-Dual Reconstruction

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Alessandro Guazzo; [2020]
    Nyckelord :PET Deep Learning Reconstruction Denoising;

    Sammanfattning : PET imaging is a key tool in the fight against cancer. One of the main issues of PET imaging is the high level of noise that characterizes the reconstructed image, during this project we implemented several algorithms with the aim of improving the reconstruction of PET images exploiting the power of Neural Networks.

  5. 4. Development of Registration and Fusion Methods for the Jonasson Medical Imaging Center MiniPET-microCT

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Dimitrios Gkotsoulias; [2018]
    Nyckelord :miniPET; microCT; Medical imaging; Multimodality imaging; Registration; Fusion; Elastix; Mutual Information;

    Sammanfattning : Multimodal image registration is essential when combining functional and structural imaging modalities. Among the most common combinations, numerous methods have been developed for co-registration of CT and PET, typically validated on human size scanners. LÄS MER

  7. 5. Multigrid reconstruction of micro-CT data

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Bo Gao; [2017]
    Nyckelord :;

    Sammanfattning : The group of Medical Imaging at School of Health and Technology is developing a micro-CT scanner for small animal imaging. Micro-CT refers to reconstructing CT image with resolution in scale of micrometer, and this goal is achieved by acquiring projection data with high resolution. LÄS MER
