Improved Breast Surface Identification for UWB Microwave Imaging

Electromagnetic ultra-wideband sensing and imaging provides perspectives for early-stage breast cancer detection. This paper deals with problems related to the accurate three-dimensional identification of the breast surface. The SEABED algorithm based on the Inverse Boundary Scattering Transform (IBST) represents a powerful basic approach for surface detection problems.

ultraMEDIS – Ultra-Wideband Sensing in Medicine

6 The project ultraMEDIS addresses the specific advantages of ultra-wideband (UWB) radio 7 sensors for medical applications: high temporal and spatial resolution, good tissue 8 penetration, low exposition by radio waves, and compatibility with existing diagnostic and 9 therapeutic equipment even for simultaneous applications. The proposed UWB sensors 10 utilize ultra-low power signals. Therefore, they are suitable for human medical applications 11 including mobile and permanent supervision of vital functions. The technique permits non12 invasive sensing with no potential risks, in contrast to catheter or X-ray techniques. A main 13 feature of ultraMEDIS is the highly synergetic technological development of UWB radar to 14 access innovative fields of applications such as UWB-navigated cardiac Magnetic Resonance 15 Imaging (MRI), heart beat monitoring, accurate modeling of electromagnetic wave 16 propagation through heterogeneous, malignant and benign biological tissue for MRI, and 17 the fast and precise identification and localization of breast cancer. 18

A Breast Surface Estimation Algorithm for UWB Microwave Imaging

Ultra-wideband sensing and imaging provides perspectives for early-stage breast cancer detection. This paper deals with problems related to the accurate three-dimensional identification of the breast surface. The applicability of the published and recently extended Boundary Scattering Transform (BST) is investigated. The so far planar scanning of the antennas is extended to a spatial scanning in order to reconstruct the whole breast region. The corresponding Boundary Scattering Transform equations for bi-static measurements are presented. The experimental study is carried out based on two female dressmaker torsos. The results demonstrate the potential of the developed approach for a shape reconstruction as a base of breast interior imaging.

Implementation of ultra-wideband sensors for biomedical applications

With the ambitious aim to exploit the specific advantages of ultra-wideband (UWB) radio sensors for medical applications the project ultraMEDIS has been designed. The project focuses on the combination of UWB radar with magnetic resonance imaging, UWB radar based breast cancer detection, identification of various physiological signatures and the development of appropriate UWB antennas to accomplish these tasks.
