    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse algorithms; microwave tomography; image reconstruction; FDTD; inverse Maxwell problem; mammography;

    Abstract : Microwave tomography for non-destructive detection of internaldielectric properties has received increasing interest during the lastdecades. Several application areas are under research, includingapplications in geoscience, biomedical applications, safety andsecurity etc. READ MORE

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

    Author : Tomas Rydholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tomography; microwave imaging; phantom; breast cancer;

    Abstract : 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. READ MORE

  5. 3. 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. 4. Ultra-Wideband Time Domain Measurement Systems for Microwave Tomography

    Author : Xuezhi Zeng; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time DomainMeasurement; Ultra-Wideband; EquivalentTime Sampling; Real Time Sampling; Microwave Tomography; Measurement Error; Frequency Domain Measurement;

    Abstract : As a potential imaging modality for biomedical applications, microwave tomography has attracted a lot of interests in recent years. With microwave tomography, microwave signals are transmitted into the biological tissues and the scattered fields are recorded. READ MORE

  7. 5. A Microwave Tomography Framework for Monitoring of Pharmaceutical Processes

    Author : Livia Cerullo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensitivity Analysis; Microwave Tomography; Reconstruction Algorithm; Parameterization; Pharmaceutical Processes;

    Abstract : Industrial pharmaceutical processes may be very difficult to monitor and control. Today, an important research fields is non-invasive measurement techniques that provide information about thematerial distribution inside the process. In this thesis, a microwave tomography (MWT) framework for monitoring of pharmaceutical processes is presented. READ MORE
