  1. 1. Evaluation of Regularized Image Reconstruction for Clinical Positron Emission Tomography

    Author : Elin Lindström; Mark Lubberink; Jens Sörensen; Anders Sundin; Anne Larsson Strömvall; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET CT; molecular imaging; image reconstruction; regularized reconstruction; quantification; oncology; neurology; cardiology; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. READ MORE

  2. 2. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

    Author : Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

    Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. READ MORE

  4. 4. Interactive 3D Image Analysis for Cranio-Maxillofacial Surgery Planning and Orthopedic Applications

    Author : Johan Nysjö; Ingela Nyström; Filip Malmberg; Ida-Maria Sintorn; Jayaram K. Udupa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image analysis; interactive segmentation; volume rendering; computed tomography; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Modern medical imaging devices are able to generate highly detailed three-dimensional (3D) images of the skeleton. Computerized image processing and analysis methods, combined with real-time volume visualization techniques, can greatly facilitate the interpretation of such images and are increasingly used in surgical planning to aid reconstruction of the skeleton after trauma or disease.

  5. 5. Unsupervised Segmentation of Head Tissues from Multi-Modal Magnetic Resonance Images: With Application to EEG Source Localization and Stroke Detection

    Author : Mahmood Qaiser; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stroke; EEG source localization; Image segmentation; reconstruction; magnetic resonance; brain;

    Abstract : The automated segmentation or labeling of individual tissues in magnetic resonance (MR) images of the human head is an essential first step in several biomedical applications. The resulting segmentation yields a patient-specific labeling of individual tissues that can be used to quantitatively characterize these tissues (e.g. READ MORE
