FREQUENCY DOMAIN SKIN ARTIFACT REMOVAL METHOD FOR ULTRA-WIDEBAND BREAST CANCER DETECTION

Frequency Domain Skin Artifact Removal Method for Ultra-Wideband Breast Cancer Detection

An Ultra Wideband Microwave Imaging System for Breast Cancer Detection

An experimental study concerning Ultra Wideband (UWB) Microwave Radar for breast cancer detection is described. A simple phantom, consisting of a cylindrical plastic container with low dielectric constant material imitating fatty tissues and a high dielectric constant object emulating tumour, is scanned with a tapered slot UWB probe antenna between 3.1 to 10.6 GHz. Different calibration schemes...

Frequency domain processing of ultra-wideband signals

The central challenge of ultra-wideband (UWB) radio is to overcome its intrinsic complexity. This paper argues for the use of high-speed sampling and a front-end FFT as the paradigm of choice for robust performance and low energy consumption in certain ultra-wideband designs. Assuming the need to approach optimal performance, it highlights the complexity advantage of frequency domain (FD) over ...

Frequency Domain Approach for CMOS Ultra-Wideband Radios

Ultra wideband (UWB) is a promising new communication scheme for short-range, high data rate applications. Processing UWB signals necessitates impractically high sampling rates for analog-to-digital converters. In this paper, we propose a new approach to address this problem.

Ultra-Wideband Pulse-Based Microwave Imaging for Breast Cancer Detection: Experimental Issues and Compensations

Recent research based on numerical modeling (Bond, 2003; Xu, 2001) that ignored hardware characteristics and simple experiments using homogenous breast phantoms (Sill, 2005; Xu, 2004) have shown the potential of ultra-wideband to detect early stage breast cancer. However, clutter interference from heterogeneous breast tissues and hardware characteristics like pulse jitter, finite dynamic range ...
