  1. 1. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Författare :Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Sammanfattning : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. LÄS MER

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

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

    Sammanfattning : 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.

  3. 3. Image analysis for volumetric characterisation of microstructure

    Författare :Maria Axelsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Digital image analysis provides methods for automatic, fast, and reproducible analysis of images. The main contribution of this thesis is new image analysis methods for volumetric characterisation of microstructure with application in the field of material science. LÄS MER

  4. 4. On Multidimensional Dynamic Fluorescence Imaging and Quantitative Image Analysis in Wide-Field Microscopy Applications to Studies of Astroglial Cells

    Författare :Siamak Khatibi; Chalmers University of Technology; []
    Nyckelord :volume estimation; astrocyte; calcium wave; intercellular signaling; volumetric image analysis; fluorescence imaging; three-dimensional 3D reconstruction; segmentation;

    Sammanfattning : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. LÄS MER

  5. 5. Investigation on the self-healing capabilties of asphaltic materials using neutron imaging

    Författare :Adrian Markari; Nicole Kringos; Anders Kaestner; Romain Balieu; Lily Poulikakos; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-healing; bituminous materials; neutron imaging; sample size effect; reconstruction; image processing; volumetric analysis; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Bitumen acts as a binding agent in asphalt mixtures where it binds the aggregates together. It is known for its potential to heal small cracks and recover its mechanical properties under the right conditions. Though this self-healing property is known, there is currently a lack of knowledge about the mechanisms that drive the process. LÄS MER
