  1. 1. Pre-planning of Individualized Ankle Implants Based on Computed Tomography - Automated Segmentation and Optimization of Acquisition Parameters

    Master-uppsats, KTH/Fysik

    Författare :Matilda Engström Messén; Elvira Moser; [2021]
    Nyckelord :osteochondral lesions of the talus; computed tomography; U-net; convolutional neural network; dice coefficient; fotled; ledbrosk; osteochondral lesion of the talus; datortomografi; U-net; convolutional neuralt nätverk; dicekoefficient;

    Sammanfattning : The structure of the ankle joint complex creates an ideal balance between mobility and stability, which enables gait. If a lesion emerges in the ankle joint complex, the anatomical structure is altered, which may disturb mobility and stability and cause intense pain. LÄS MER

  3. 2. Simulation of Detector Response : How Does the Electron Multiplication Differ Within Ionization Chambers with Various Geometries?

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Matilda Messén; Elvira Moser; [2019]
    Nyckelord :nuclear physics; simulation model; ionization chamber; electron multiplication; Python 3.7; inner radius; anode wire radius; electric field strength; multiplication peak;

    Sammanfattning : This degree project was performed in collaboration with the division of nuclear physics at the department of physics, KTH Royal Institute of Technology. A partial goal of the project was to create a simulation model, where the relationship be- tween the multiplication of electrons that occurs in an ionization chamber and the different pressures of air in the detector could be visualized.
