  2. 2. Detecting Inclusions in a Silicone Rubber Phantom Using Standing Lamb Waves and Multiple Frequency Footprints

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Ulf G Jonsson; Umeå universitet.; Umeå universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; Silicone rubber; Impedance; Resonance; Lamb waves; Phantom; Electronics; elektronik;

    Sammanfattning : The thesis deals with one major question: is it possible, using one piezoelectric sensor/vibrator, to detect a hard inclusion in a silicone rubber phantom? The question was approached with an open mind and the task was subdivided into three clearly identifiable parts: characterization of the piezoelectric sensor/vibrator (paper I), creating a model of the visco-elastic properties of a tissue-like material (phantom) in contact with the sensor/vibrator (paper II), and to detect the presence of a hard inclusion in the phantom (paper III). All vibrations of the sensor/vibrator and phantom was modeled using a finite element method (FEM). LÄS MER

  3. 3. Phantom of the Neighbourhood : Longitudinal Studies on Area-based Conditions and Individual Outcomes

    Detta är en avhandling från Swedish Institute for Social Research

    Författare :Lars Brännström; Stockholms universitet.; Stockholms universitet.; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neighbourhood effects; Contextual effects; Residential segregation; Sweden; SOCIAL SCIENCES Social sciences Sociology; SAMHÄLLSVETENSKAP Socialvetenskap Sociologi;

    Sammanfattning : This dissertation consists of three self-contained but interrelated empirical studies focusing on theoretical, empirical and political questions in the multidisciplinary field of neighbourhood effect research. Along with a comprehensive introductory essay, each study addresses questions concerning the potential influence of neighbourhood characteristics on individual social and economic outcomes at different life stages.

  4. 4. Experimental Evaluation of a Microwave Tomography System for Breast Cancer Detection

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Tomas Rydholm; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tomography; microwave imaging; phantom; breast cancer;

    Sammanfattning : Microwave tomography is a potential candidate for future breast-cancer screening or diagnosis. Contrary to x-rays, microwaves are non-ionizing and therefore not a health risk by their own. The examination procedure would also be more comfortable for the patient compared to conventional mammography since no compression of the breast is needed. LÄS MER

  5. 5. Ultrasonic Methods for Quantitative Carotid Plaque Characterization

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Erik Widman; KTH.; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknologi; Medical Technology; Atherosclerosis; Cardiovascular Disease; Carotid Artery; Elasticity; ex vivo; in vivo; Phantom; Plaque; Polyvinyl Alcohol; Pulse Wave Imaging; Shear Wave Elastography; Speckle Tracking; Stroke; Ultrasound;

    Sammanfattning : Cardiovascular diseases are the leading causes of death worldwide and improved diagnostic methods are needed for early intervention and to select the most suitable treatment for patients. Currently, carotid artery plaque vulnerability is typically determined by visually assessing ultrasound B-mode images, which is influenced by user-subjectivity. LÄS MER
