  1. 1. Anatomical segmentation of the human brain: comparative assessment of two automatic methods

    University essay from

    Author : Carl von Dorrien; [2023-08-22]
    Keywords : Medical physics; MAPER; FreeSurfer; FastSurfer; Automatic brain segmentation; MRI; Deep Neural Network; Brain;

    Abstract : Magnetic Resonance Imaging (MRI) is a robust and versatile imaging modality and an integral component of a lot of studies, especially when performing quantitative analysis. MRI is the preferred method of imaging the brain because of its excellent soft tissue contrast. READ MORE

  3. 2. Cytokine capture with beads in cytotoxicity assays in microwells

    University essay from KTH/Tillämpad fysik

    Author : Maxime Simon; [2023]
    Keywords : Microbead; Inteferon gamma; Natural Killer cells; microwell; binding-reaction model; Mikrokula; Interferon gamma; Naturliga Mördarceller; Mikrobrunn; modell för bindningsreaktion;

    Abstract : Cytokines are small, secreted proteins that are important for cell signalling in theimmune system. Interferon gamma (IFN-γ) is one of the most potent cytokines thatnatural killer (NK) cells of the innate immune system secrete with both antiviral,antibacterial, and antitumoral activity. READ MORE

  4. 3. Methods to study device induced aggregation of proteins

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Marie Therese von Wowern; [2023]
    Keywords : protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

    Abstract : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. READ MORE

  5. 4. Detection of local motion artifacts and image background in laser speckle contrast imaging

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Johannes Nyhlén; Märta Sund; [2023]
    Keywords : laser speckle contrast imaging; lsci; multi exposure laser speckle contrast imaging; melsci; machine learning; deep learning; statistical analysis; detection; local motion artifacts; 1D; 2D; 3D;

    Abstract : Laser speckle contrast imaging (LSCI) and its extension, multi-exposure laser speckle contrast imaging (MELSCI) are non-invasive techniques to monitor peripheral blood perfusion. One of the main drawbacks of LSCI and MELSCI in clinical use is that the techniques are sensitive to tissue movement. READ MORE

  6. 5. Improving the experimental setup for ultrasound-optical tomography imaging

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ibtisam Dahir Ahmed; [2023]
    Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE
