  1. 1. Robust Image Registration for Improved Clinical Efficiency Using Local Structure Analysis and Model-Based Processing

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Daniel Forsberg; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; deformable models; scoliosis; visualization; volume rendering; adaptive regularization; GPGPU; CUDA;

    Sammanfattning : Medical imaging plays an increasingly important role in modern healthcare. In medical imaging, it is often relevant to relate different images to each other, something which can prove challenging, since there rarely exists a pre-defined mapping between the pixels in different images.

  2. 2. MRI based radiotherapy planning and pulse sequence optimization

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jens Sjölund; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more effective radiotherapy treatments with fewer side effects. LÄS MER

  3. 3. A Global Linear Optimization Framework for Adaptive Filtering and Image Registration

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Gustaf Johansson; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global Linear Optimization; Linear Optimization; Regularization; Medical Image Registration; Structure Tensor;

    Sammanfattning : Digital medical atlases can contain anatomical information which is valuable for medical doctors in diagnosing and treating illnesses. The increased availability of such atlases has created an interest for computer algorithms which are capable of integrating such atlas information into patient specific dataprocessing. LÄS MER

  4. 4. Manifold learning and representations for image analysis and visualization

    Detta är en avhandling från Institutionen för medicinsk teknik

    Författare :Anders Brun; Linköpings universitet.; Linköpings universitet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; MEDICINE Physiology and pharmacology Physiology Medical informatics; MEDICIN Fysiologi och farmakologi Fysiologi Medicinsk informatik;

    Sammanfattning : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. LÄS MER

  5. 5. Probing intestinal permeability in man using different-sized, low-molecular-weight polyethyleneglycols and mathematical modelling

    Detta är en avhandling från Vimmerby : VTT Grafiska

    Författare :Tommy Sundqvist; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [1981]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : Selective intestinal permeability as reflected by the urinary recovery of low-molecular-weight polyethylene glycols (PEG 400) of dlfferentsizes after oral administration was characterized with a mathematical filter-function. There was relative loss of both large and small PEG molecules on their way from the intestine to the urine. LÄS MER
