Channel-ranked beamformer for the early detection of breast cancer
(EMW Publishing, 2010-01-01)Confocal Microwave Imaging (CMI) for the early detection of breast cancer is based on several assumptions regarding the dielectric properties of normal and malignant breast tissue. One of these assumptions is that the ... -
Data independent radar beamforming algorithms for breast cancer detection
(EMW Publishing, 2010-01-01)Ultra wideband (UWB) Microwave imaging is one of the most promising emerging imaging technologies for breast cancer detection, and is based on the dielectric contrast between normal and cancerous tissues at microwave ... -
Effects of fibroglandular tissue distribution on data-independent beamforming algorithms
(EMW Publishing, 2009-01-01)The effects of the fibroglandular tissue distribution of the breast on data-independent microwave imaging algorithms are investigated in this paper. A data-independent beamformer is a beamformer whose weights do not depend ... -
Investigation of classifiers for early-stage breast cancer based on radar target signatures
(EMW Publishing, 2010-01-01)Ultra Wideband (UWB) radar has been extensively investigated as a means of detecting early-stage breast cancer. The basis for this imaging modality is the dielectric contrast between normal and cancerous breast tissue at ... -
Microwave breast imaging: experimental tumour phantoms for the evaluation of new breast cancer diagnosis systems
(IOP Publishing, 2018-01-29)In this paper, a new set of tumour phantoms for the experimental evaluation of Microwave Breast Imaging (MBI) as a method to diagnose breast cancer is presented. The phantoms were based on previously developed numerical ... -
Parameter search algorithms for microwave radar-based breast imaging: focal quality metrics as fitness functions
(MDPI AG, 2017-12-06)Inaccurate estimation of average dielectric properties can have a tangible impact on microwave radar-based breast images. Despite this, recent patient imaging studies have used a fixed estimate although this is known to ... -
Performance and robustness of a multistatic mist beamforming algorithm for breast cancer detection
(EMW Publishing, 2010-01-01)Ultra-Wideband (UWB) radar is one of the most promising emerging technologies for the early detection of breast cancer, and the development of robust beamforming algorithms for imaging has been the subject of a significant ... -
Rotating antenna microwave imaging system for breast cancer detection
(EMW Publishing, 2010-01-01)Breast imaging using Confocal Microwave Imaging (CMI) has becoming a difficult problem, primarily due to the recently-established dielectric heterogeneity of normal breast tissue. CMI for breast cancer detection was ... -
Spiking neural networks for breast cancer classification in a dielectrically heterogeneous breast
(EMW Publishing, 2011-01-01)The considerable overlap in the dielectric properties of benign and malignant tissue at microwave frequencies means that breast tumour classification using traditional UWB Radar imaging algorithms could be very problematic. ...
