  1. 1. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon

    Master-uppsats, KTH/Fysik

    Författare :Rickard Brunskog; [2022]
    Nyckelord :Phase-contrast imaging; phase-contrast; CT-scanning; Computed-tomography; 1 micrometer resolution x-ray; grating-less phase-contrast imaging; Faskontraströntgen; faskontrast; CT-skanning; 1 mikrometer upplösning x-ray; gitterlös faskontrast; datortomografi;

    Sammanfattning : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. LÄS MER

  3. 2. Methods for Estimating the Magnetic Dipole Moment of Small Objects

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

    Författare :Elina Arvidsson; Rickard Brunskog; [2020]
    Nyckelord :MIST; student satellite; CubeSat; magneticdipole moment; magnetometer;

    Sammanfattning : A small satellite can be adversely affected by Earth’s magnetic field due to the resulting torque the magnetic field exerts on the satellites magnetic dipole moment. Therefore, this dipole moment needs to be estimated during the development of the satellite to make sure that the torque does not become a problem once the satellite is in orbit. LÄS MER
