  1. 1. Positron Emission Tomography with Three-Dimensional Reconstruction

    University dissertation from Radiation Physics, Lund

    Author : Kjell Erlandsson; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; quantitation; reconstruction; three-dimensional; tomography; positron; emission; 3D; PET; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In this thesis, the developments of two different low-cost scanners for positron emission tomography (PET) based on 3D acquisition, are presented. 3D reconstruction methods for these systems are also presented. READ MORE

  2. 2. Direct Fourier methods in 3D-reconstruction from cone-beam data

    University dissertation from Linköping : Linköpings universitet

    Author : Caroline Axelsson; Linköpings universitet.; Linköpings universitet.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The problem of 3D-reconstruction is encountered in both medical and industrial applications of X-ray tomography. It would seem natural to recover volume data by just repeating 2D-reconstructions slice-by-slice. READ MORE

  3. 3. Development of Techniques for 3D Imaging with Focused Ion Beams - Hydrogen Depth Profiling and Microtomography with Applications in Geology

    University dissertation from Division of Nuclear Physics Department of Physics Lund University Box 118 SE-221 00 Lund Sweden

    Author : Marie Wegdén; Lund University.; Lunds universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen analysis; Depth profiling; Ion beam analysis; Nuclear microprobe; Physics; Nuclear physics; Fysik; Fysicumarkivet A:2007:Wegdén; Kärnfysik; Tomography; 3D Imaging;

    Abstract : In nuclear microprobe experiments, high resolution maps of the measured parameter, e.g. element- or mass distribution, in a sample can be produced with a variety of ion beam analytical techniques. The principle underlying all the techniques is that ions at MeV energies are used as projectiles to cause interactions with the target material. READ MORE

  4. 4. Structural study of nano-structured materials: electron crystallography approaches

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Author : Yanhang Ma; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structural analysis; electron crystallography; 3D EDT; HRTEM imaging; defects; oorganisk kemi; Inorganic Chemistry;

    Abstract : The structural analysis serves as a bridge to link the structure of materials to their properties. Revealing the structure details allows a better understanding on the growth mechanisms and properties of materials, and a further designed synthesis of functional materials. READ MORE

  5. 5. Digital holography and image processing methods for applications in biophysics

    University dissertation from Umeå : Umeå University

    Author : Hanqing Zhang; Umeå universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital holographic microscopy; image processing; image reconstruction; bacterial adhesion; cell morphology; algorithm development; software design; quantitative measurement; microfluidics; multidisciplinary research; Signal Processing; signalbehandling; Technical Physics; teknisk fysik med inriktningen mikrosystemteknik;

    Abstract : Understanding dynamic mechanisms, morphology and behavior of bacteria are important to develop new therapeutics to cure diseases. For example, bacterial adhesion mechanisms are prerequisites for initiation of infections and for several bacterial strains this adhesion process is mediated by adhesive surface organelles, also known as fimbriae.
