  1. 1. Design of Instrumentation & Control and Optical Table Instruments for the Divertor Flow Monitor Diagnostic at ITER

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Niklas Hermansson; [2022]
    Keywords : Coherence imaging; fusion; optics; plasma diagnostic; polarization; spectroscopy; Zeeman-Doppler imaging;

    Abstract : This master's thesis describes the process of the design and instrument selection for a future optical table, part of a plasma flow monitor diagnostic system at the international thermonuclear experimental reactor, ITER. The diagnostic system is designed to detect the presence of edge localized mode, low to high confinement mode transition of plasma, and plasma flow velocity in the divertor region of the reactor.

  3. 2. Relation between retinal morphology, visual pathway integrity and plasmatic amyloid beta 42 peptide in old and young beagles

    University essay from SLU/Dept. of Clinical Sciences

    Author : Emilia Miranda Peluso; [2020]
    Keywords : cognitive dysfunction syndrome; dog; optical coherence tomography; OCT; visual evoked potentials; VEP;

    Abstract : The spontaneously occurring behavioural syndrome referred to as canine cognitive dysfunction (CCD) is considered the canine counterpart of Alzheimer’s disease (AD). Changes in the retina such as nerve fibre layer (NFL) and ganglion cell complex (GCC) thinning have been observed in Alzheimer’s patients. READ MORE

  4. 3. In-line Phase-contrast Tomography using Betatron X-rays Produced by a Laser-Plasma Accelerator

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Kristoffer Svendsen; [2017]
    Keywords : source size; x-ray; in-line; phase-contrast; phase contrast; LWFA; laser wakefield acceleration; tomography; diffraction; diffraction simulation; laser-plasma acceleration; Physics and Astronomy;

    Abstract : X-ray phase-contrast imaging is a powerful technique that allows great resolving power for low absorbing samples, such as biological tissue. This method relies on measuring the phase shift induced by the sample instead of the absorption traditional radiography relies on. READ MORE

  5. 4. Processing of Optical Coherence Tomography Images : Filtering and Segmentation of Pathological Thyroid Tissue

    University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Medicinska fakulteten

    Author : Daniela Koller; [2016]
    Keywords : ;

    Abstract : In the human body, the main function of the healthy thyroid gland is the regulation of the metabolism and hormone production. Included in the thyroid are organized structured and uniformly shaped follicles ranging from 50-500 μm in diameter. READ MORE

  6. 5. Tissue identification for thyroid and parathyroid surgery : using optical coherence tomography and fluorescence spectroscopy

    University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Tekniska fakulteten

    Author : Pernilla Petersson; [2015]
    Keywords : ;

    Abstract : Bakgrund och Mål: Under sköldkörtel- och bisköldkörteloperationer är det viktigt att inte förstöra eller ta bort friska bisköldkörtlar för att inte påverka deras hormonproduktionen. Bisköldkörtlarna kan vara svåra att upptäcka eftersom de kan variera i storlek och placering samt att deras vävnad kan vara lik omkringliggande vävnad. READ MORE
