  1. 16. Deep Regression and Segmentation for Medical Inference from Large-Scale Magnetic Resonance Imaging

    Författare :Taro Langner; Joel Kullberg; Anders Eklund; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; medical image analysis; neural networks; machine learning; semantic segmentation; deep regression; saliency analysis; uncertainty quantification; UK Biobank; Medical Informatics; Medicinsk informatik;

    Sammanfattning : Large-scale studies, such as UK Biobank, acquire medical imaging data for thousands of participants. With magnetic resonance imaging (MRI), comprehensive representations of human anatomy can be provided for non-invasive assessments of health-related conditions, body composition, organ volumes, and more.

  3. 17. 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

  4. 18. 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. 19. Level Set Segmentation and Volume Visualization of Vascular Trees

    Författare :Gunnar Läthén; Reiner Lenz; Magnus Borga; Lasse Riis Østergaard; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; level set methods; image segmentation; edge detection; visualization; volume rendering; blood vessels; angiography; vascular trees;

    Sammanfattning : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. LÄS MER
