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

    Författare :Siamak Khatibi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  3. 22. CT colonography. Technique, diagnostic accuracy and patient acceptance

    Författare :Maria H Svensson (Reutersköld); Göteborgs universitet; []
    Nyckelord :Colon; Rectum; Computed tomography; Three-dimensional imaging; Colorectal neoplasms; Colonic polyps; Colonoscopy; Acceptance testing; Incidental findings; Diagnostic accuracy;

    Sammanfattning : The aim was to evaluate diagnostic potential, technical performance, and patient acceptance of CT colonography when used for detection of colorectal polyps and cancer in symptomatic patients with a high risk of colorectal neoplasia.Methods: After bowel preparation, 111 symptomatic patients underwent CT colonography followed by conventional colonoscopy.

  4. 23. CT Colonography: implementation and technical developments

    Författare :Valeria A Fisichella; Göteborgs universitet; []
    Nyckelord :X-ray Computed Tomography; Computed Tomographic Colonography; Computer-Assisted Image Processing; Three-Dimensional Imaging; Colonoscopy; Colon; Rectum; Colorectal Neoplasms; Computer-Assisted Diagnosis; Ionizing Radiation;

    Sammanfattning : Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care.

  7. 25. Three dimensional data analysis for the separation and sizing of laboratory rock piles

    Författare :Matthew Thurley; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The size distribution of piles of blasted and crushed rock in mining is so closely related to the economics of the mine that it must be measured quickly and accurately. This thesis develops a mathematical and 3D imaging solution for determining the size distribution of laboratory rock piles based on surface measurements of the pile... LÄS MER
