Microwave Imaging of the Breast

Microwave Breast Imaging

Contrast-enhanced microwave imaging of breast tumors

The detection of early-stage tumors in the breast by microwave imaging is challenged by both the moderate endogenous dielectric contrast between healthy and malignant glandular tissues and the spatial resolution available from illumination at microwave frequencies. The high endogenous dielectric contrast between adipose and fibroglandular tissue structures increases the difficulty of tumor dete...

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. ...

Title : Microwave tomographic imaging for breast cancer

Microwave imaging has received a great amount of interest in last few decades in view of biomedical applications such as breast tumor detection. The potential advantages of microwave imaging as an alternative to X ray Computed Tomography (CT) are: i) the non negligible contrast that exists between the dielectric properties of normal and malignant breast tissues, ii) the non-ionizing nature of m...

Active Microwave Imaging for Breast Cancer Detection

Active microwave imaging is explored as an imaging modality for early detection of breast cancer. When exposed to microwaves, breast tumor exhibits electrical properties that are significantly different from that of healthy breast tissues. The two approaches of active microwave imaging — confocal microwave technique with measured reflected signals and microwave tomographic imaging with measured...
