  2. 1. Atlas-Based Fusion of Medical Brain Images : Methods and Applications

    Author : Roger Lundqvist; Hans Knutsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : This thesis focuses on the development of methods for fusion of information from medical brain scans. The concept of medical image fusion refers to the process of extracting and utilising information from several scans simultaneously in the analysis and diagnosis of patients. READ MORE

  4. 2. Advances in brain SPECT : methodological and human investigations

    Author : Marco Pagani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : SPECT; 99Tcm-HMPAO; Computerised Brain Atlas; rC13F; Control Subjects; Alzheimer s Disease; Frontal Lobe Dementia;

    Abstract : The aim of this work was to optimise and validate a new approach for examination of die regional cerebral blood flow (rCBF) using Single Photon Emission Computed Tomography (SPECT) for application in clinical research and patient care. It also involved the implementation of a software system for evaluation and analysis of rCBF. READ MORE

  5. 3. Principles of regional covariance in brain structure

    Author : Lars Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human brain varies between individuals in both shape and size. These variations are not unique for each brain region. This causes grey matter density between regions to covary, a phenomenon known as “structural brain covariance”. READ MORE

  6. 4. Advances in quantitative emission tomography : development and analysis of methods for validation and correction

    Author : Cathrine Jonsson; Magnus Dahlbom; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SPECT; Quantification; rCBF; Scatter correction; Phantoms; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : The nuclear medicine imaging techniques SPECT and PET are sensitive tools in mapping various physiological and biochemical processes in vivo. This work was devoted to investigations of methodological and physical properties of the SPECT technique as well as developing methods for validation and correction. READ MORE
