  2. 1. Assessment of Body Composition Using Magnetic Resonance Imaging

    Author : Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
    Keywords : Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

    Abstract : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. READ MORE

  4. 2. Water–fat separation in magnetic resonance imaging and its application in studies of brown adipose tissue

    Author : Jonathan Andersson; Joel Kullberg; Håkan Ahlström; Mark Lubberink; Kerstin Lagerstrand; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brown adipose tissue; magnetic resonance imaging; water–fat signal separation; graph-cut; positron emission tomography; 18F-fludeoxyglucose; infrared thermography; machine learning; artificial neural networks; deep learning; convolutional neural networks; Radiology; Radiologi;

    Abstract : Virtually all the magnetic resonance imaging (MRI) signal of a human originates from water and fat molecules. By utilizing the property chemical shift the signal can be separated, creating water- and fat-only images. READ MORE

  5. 3. Separation of Water and Fat Signal in Magnetic Resonance Imaging : Advances in Methods Based on Chemical Shift

    Author : Johan Berglund; Joel Kullberg; Lars Johansson; Håkan Ahlström; Zhi-Pei Liang; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Magnetic resonance imaging; digital image reconstruction; chemical shift imaging; water and fat separation; Dixon method; fat suppression; quantitative MRI; whole-body MRI; fatty acid composition; fat unsaturation; triglycerides; adipose tissue; liver fat; T2* mapping; Radiology; Radiologi; Radiology; Radiologi;

    Abstract : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. READ MORE

  6. 4. Image Processing and Analysis Methods for Biomedical Applications

    Author : Eva Breznik; Robin Strand; Filip Malmberg; Joel Kullberg; Håkan Ahlström; Alejandro Frangi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple comparisons; image segmentation; image retrieval; deep learning; medical image analysis; magnetic resonance imaging; whole-body imaging; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : With new technologies and developments medical images can be acquired more quickly and at a larger scale than ever before. However, increased amount of data induces an overhead in the human labour needed for its inspection and analysis. READ MORE

  7. 5. Efficient GPU-based Image Registration : for Detailed Large-Scale Whole-body Analysis
