  1. 11. Segmentation and Visualisation of Human Brain Structures

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

    Sammanfattning : 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. 14. Methods and models for 2D and 3D image analysis in microscopy, in particular for the study of muscle cells

    Författare :Patrick Karlsson Edlund; Ewert Bengtsson; Joakim Lindblad; Carolina Wählby; Fritz Albregtsen; Uppsala universitet; []
    Nyckelord :medical image analysis; image segmentation; fluorescence microscopy; cytometry; human skeletal muscle;

    Sammanfattning : Many research questions in biological research lead to numerous microscope images that need to be evaluated. Here digital image cytometry, i.e., quantitative, automated or semi-automated analysis of the images is an important rapidly growing discipline. LÄS MER

  7. 15. Image Analysis Methods and Tools for Digital Histopathology Applications Relevant to Breast Cancer Diagnosis

    Författare :Andreas Kårsnäs; Robin Strand; Carolina Wählby; Ewert Bengtsson; Anant Madabhushi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; breast cancer diagnosis; digital histopathology; immunohistochemistry; biomarker quantification; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : In 2012, more than 1.6 million new cases of breast cancer were diagnosed and about half a million women died of breast cancer. The incidence has increased in the developing world. The mortality, however, has decreased. LÄS MER
