  1. 11. Development of methods and software for rapid quality control in fluoroscopy

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Majid Khosamadi; [2021]
    Nyckelord :;

    Sammanfattning : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. LÄS MER

  3. 12. A Camera System for the KTH MIST Satellite

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

    Författare :Volkan Coskun; [2020]
    Nyckelord :;

    Sammanfattning : The KTH MIST satellite will include a Camera System that should capture pictures of Earth from Space. Due to low Bandwidth, the satellite can traverse several lapses around the Earth until the picture is transmitted down to Earth. The picture is processed and the raw pixels stored in an on-board DRAM. LÄS MER

  4. 13. 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. 14. Generation and characterization of intense attosecond XUV pulses

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Xiuyu Wu; [2019]
    Nyckelord :;

    Sammanfattning : Electronic dynamics in molecules and atoms takes place on the attosecond timescale. For the observation of such processes, measurement techniques with attosecond resolution are needed. LÄS MER

  7. 15. A Near-Infrared Diffraction Radiation Spectrometer for MHz Repetition Rate Electron Bunch Diagnostics at the European XFEL

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Simon Fahlström; [2019]
    Nyckelord :European XFEL; XFEL; Free-Electron Laser; FEL; bunch diagnostics; Coherent Diffraction Radiation; Spectrometer;

    Sammanfattning : We have built a spectrometer to investigate the Near-Infrared (NIR) range of this radiation, which is used for bunch diagnostics at the European X-ray Free-Electron Laser. This could give information on the development of microbunching, periodic features in the longitudinal charge profile of the bunches which have a negative impact on the operation of the facility.
