Heterogeneous Breast Phantom Development for Microwave Imaging Using Regression Models

Heterogeneous Breast Phantom Development for Microwave Imaging Using Regression Models

As new algorithms for microwave imaging emerge, it is important to have standard accurate benchmarking tests. Currently, most researchers use homogeneous phantoms for testing new algorithms. These simple structures lack the heterogeneity of the dielectric properties of human tissue and are inadequate for testing these algorithms for medical imaging. To adequately test breast microwave imaging a...

Microwave Imaging Using SAR

Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...

QUANTITATIVE MICROWAVE BREAST PHANTOM IMAGING USING A PLANAR 2.45 GHz SYSTEM

Breast cancer is a global health problem, needing cheep and effective alternative diagnosis methods in order to minimize the mortality. This experimental study is performed in the context of an ongoing collaborative project towards a future planar three-dimensional microwave breast mammography system. Herein the first quantitative image of an inhomogeneous breast tumor phantom, composed by diff...

A Method for 3D Breast Cancer Imaging using Microwave Holography

This work describes a technique which has been developed for the detection and imaging of breast cancer tumours. It describes how 3D images can be reconstructed from 2D scalar intensity patterns, or holograms. An outline of the background theory in described followed by experimental results on paraffin wax breast phantoms Results demonstrate that this technique is capable of determining the loc...
