  2. 1. On large-scale neural simulations and applications in neuroinformatics

    Author : Simon Benjaminsson; Anders Lansner; Marc-Oliver Gewaltig; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of three parts related to the in silico study of the brain: technologies for large-scale neural simulations, neural algorithms and models and applications in large-scale data analysis in neuroinformatics. All parts rely on the use of supercomputers. READ MORE

  4. 2. Segmentation and Visualisation of Human Brain Structures

    Author : Roger Hult; Ewert Bengtsson; Lennart Thurfjell; Håkan Hall; Ingrid Agartz; Arvid Lundervold; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).

  5. 3. From Industry to Practice: Can Users Tackle Domain Tasks with Augmented Reality?

    Author : Yuchong Zhang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Qualitative and Quantitative Analysis; Human-centered Design; User Study; Industrial Process Tomography; Augmented Reality;

    Abstract : Augmented Reality (AR) is a cutting-edge interactive technology. While Virtual Reality (VR) is based on completely virtual and immersive environments, AR superimposes virtual objects onto the real world. READ MORE

  6. 4. Novel Approaches for Application of Principal Component Analysis on Dynamic PET Images for Improvement of Image Quality and Clinical Diagnosis

    Author : Pasha Razifar; Ewert Bengtsson; Mats Bergström; Harald Schneider; Habib Zaidi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Dynamic PET; Noise Correlation; PCA; Image Quality; Slice-Wise; Pixel-Wise; Masked-Volume-Wise; Pre-normalization; Bildanalys; Image analysis; Bildanalys;

    Abstract : Positron Emission Tomography, PET, can be used for dynamic studies in humans. In such studies a selected part of the body, often the whole brain, is imaged repeatedly after administration of a radiolabelled tracer. READ MORE

  7. 5. Monitoring cystic fibrosis lung disease in children - Clinical utility and associations between functional and structural methods

    Author : Marcus Svedberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cystic fibrosis; children; lung disease;

    Abstract : Background: Cystic Fibrosis (CF) is an inherited progressive disease that causes severe damage to the airways and other organs of the body. Many methods are available to track CF lung disease but longitudinal data are needed to better understand the clinical utility and associations between different methods. READ MORE
