This book was released on 2016-07-13 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collates past and current research on one of the most promising emerging modalities for breast cancer detection. Readers will discover how, as a standalone technology or in conjunction with another modality, microwave imaging has the potential to provide reliable, safe and comfortable breast exams at low cost. Current breast imaging modalities include X- ray, Ultrasound, Magnetic Resonance Imaging, and Positron Emission Tomography. Each of these methods suffers from limitations, including poor sensitivity or specificity, high cost, patient discomfort, and exposure to potentially harmful ionising radiation. Microwave breast imaging is based on a contrast in the dielectric properties of breast tissue that exists at microwave frequencies. The book begins by considering the anatomy and dielectric properties of the breast, contrasting historical and recent studies. Next, radar-based breast imaging algorithms are discussed, encompassing both early-stage artefact removal, and data independent and adaptive beamforming algorithms. In a similar fashion, microwave tomographic reconstruction algorithms are reviewed in the following chapter, introducing the reader to both the fundamental and more advanced algorithms. Apart from imaging, the book also reviews research efforts in extracting clinically useful information from the Radar Target Signature of breast tumours, which is used to classify tumours as either benign or malignant. Finally, the book concludes by describing the current state of the art in terms of prototype microwave breast imaging systems, with a particular emphasis on those which have progressed to the clinical evaluation stage. This work is motivated by the fact that breast cancer is one of the leading causes of death amongst women in Europe and the US, and the second most common cancer in the world today. Such an important area of research will appeal to many scholars and practitioners.p>

Available in PDF, EPUB and Kindle. Book excerpt: We overview the research trend on microwave imaging for early breast cancer detection. The technologies have two categories: ultra-wide band (UWB) radar that reconstructs the scattering power distribution in the breast and inverse scattering problem that reconstructs the dielectric properties distribution. We have developed a clinical equipment using UWB radar and carried out clinical test 4 years ago. Through the experiments, we concluded that the UWB radar was insufficient for the clinical equipment, because the UWB radar cannot discriminate cancerous tumor and other lesions. Therefore, we have been studying inverse scattering. It is a challenging task to develop an equipment using inverse scattering technologies. We have proposed a microwave mammography that has four features: (1) sensor with breast fixing by absorption, (2) small sensor with multipolarization, (3) image reconstruction program linking the commercial EM simulator, and (4) hybrid imaging method using UWB radar and inverse scattering.

This book was released on 2017 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conventional breast cancer detection methods have limitations ranging from ionizing radiations, low specificity to high cost. These limitations make way for a suitable alternative called Microwave Imaging, as a screening technique in the detection of breast cancer. The discernible differences between the benign, malignant and healthy breast tissues and the ability to overcome the harmful effects of ionizing radiations make microwave imaging, a feasible breast cancer detection technique. Earlier studies have shown the variation of electrical properties of healthy and malignant tissues as a function of frequency and hence stimulates high bandwidth requirement. A Ultrawideband, Wideband and Narrowband arrays have been designed, simulated and optimized for high (44%), medium (33%) and low (7%) bandwidths respectively, using the EM (electromagnetic software) called FEKO. These arrays are then used to illuminate the breast model (phantom) and the received backscattered signals are obtained in the near field for each case. The Microwave Imaging via Space-Time (MIST) beamforming algorithm in the frequency domain, is next applied to these near field backscattered monostatic frequency response signals for the image reconstruction of the breast model. The main purpose of this investigation is to access the impact of bandwidth and implement a novel imaging technique for use in the early detection of breast cancer. Earlier studies show the implementation of the MIST imaging algorithm on the time domain signals via a frequency domain beamformer. The performance evaluation of the imaging algorithm on the frequency response signals has been carried out in the frequency domain. The energy profile of the breast in the spatial domain is created via the frequency domain Parseval’s theorem. The beamformer weights calculated using these the MIST algorithm (not including the effect of the skin) has been calculated for Ultrawideband, Wideband and Narrowband arrays, respectively. Quality metrics such as dynamic range, radiometric resolution etc. are also evaluated for all the three types of arrays.

Available in PDF, EPUB and Kindle. Book excerpt: "Early detection of breast cancer is vital for successful treatment of the disease. The current standard screening technology is X-ray mammography; however, it exposes the breast to ionizing radiation and painful compression, with poor sensitivity in dense tissues. Microwave imaging of the breast has been proposed in recent years as a complementary modality to X-ray mammography. Based on the contrast in dielectric properties of healthy and malignant breast tissues, microwave techniques offer the potential for low-cost, non-invasive breast screening without ionizing radiation.This thesis presents a newly developed experimental system for time-domain microwave breast cancer detection using multistatic radar. The system operates by transmitting a short-duration pulse into the breast, and collecting the scattered response. The long-term goal of this research is to develop a breast monitoring system that can track healthy patients with regular breast scans, comparing past and present ones to detect a possible abnormality at an early stage. The thesis first presents successful imaging of tumors in realistic breast phantoms, after compensation of measurement noise using a cross-correlation method for signal time-alignment. Then, the system is integrated into a patient-ready interface, and two clinical trials are performed: one trial follows 13 healthy patients over an 8-month period with monthly breast scans (total of 342 breast scans), and the other tracks a single patient with daily scans over one month (total of 108 scans). These trials are the first attempt at breast monitoring, with patients, using a time-domain microwave system. Data from the trials is used to quantify the level of change seen in both collected signals and reconstructed images due to healthy tissue variations. It is found that for several of the patients, the results are highly consistent over all scan occasions; however, the results for some patients are lacking in repeatability. Through this clinical trial, several potential avenues for improvement and optimization of the system have been identified. The thesis then presents the development of three wideband, flexible antennas for a microwave breast imaging application. The antennas are designed for use over the 2 - 4 GHz range, and are optimized for direct contact with the skin. The antenna behaviour is fully characterized, with return loss below -10 dB for all flexing positions, for measurements both on phantom and on-body. One of the antennas (a rectangular patch) is selected for implementation in a novel wearable array for breast imaging. The array is embedded in a bra, and a month-long clinical trial of daily scans of one patient is conducted. The wearable array represents a significant step forward in terms of a microwave system for breast monitoring, as the antennas and radome structure are both extremely cost-effective, lightweight, and relatively compact. The trial results with the new array demonstrate improved consistency in scans over that of the original trial scenario, and offer promise for future breast monitoring systems. " --
