  5. 33. Fast Microwave Tomography Algorithm for Breast Cancer Imaging

    Author : Samar Hosseinzadegan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breast cancer; computational cost; inverse problem; discrete dipole approximation; microwave tomography; forward solver; Jacobian matrix;

    Abstract : Microwave tomography has shown promise for breast cancer imaging. The microwaves are harmless to body tissues, which makes microwave tomography a safe adjuvant screening to mammography. READ MORE

  6. 34. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography

    Author : Magnus Gedda; Ewert Bengtsson; Stina Svensson; Carolina Wählby; Punam Saha; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; digital image analysis; 3D; fuzzy; algorithms; grey-weighted distance; region growing; electron tomography; tracing; fluorescence microscopy; Datoriserad bildanalys; Computerized Image Analysis;

    Abstract : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. READ MORE

  7. 35. Nanoscale Osseointegration : Characterization of Biomaterials and their Interfaces with Electron Tomography
