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>

Book excerpt: "Breast cancer, one of the primary causes of women mortality worldwide, can be effectively treated if detected at its early stage. Microwave Imaging (MWI), an emerging technique, promises to complement the currently used diagnostic modalities. It is safe, non-ionizing and potentially inexpensive, thus possessing key features to make it a good candidate for frequent and mass screenings. This thesis summarizes results of novel research done towards a prototype of a microwave device aimed at screening breast tissues. The author first presents the results of a research to combine Microwave Radar (MWR) breast imaging technique with Microwave-Induced Thermoacoustic (MWIT) imaging to improve tumor detection rate. An optimal rule for fusing information from the two modalities is developed and applied to numerically-simulated microwave and acoustic signals. The results demonstrate advantages of the hybrid method, compared to the MWR and MWIT methods used individually. Next, the thesis describes a research study to address the challenge of data acquisition in MWI. Recording microwave signals with high signal-to-noise ratio is either too expensive or suffers from numerous artifacts and measurement errors. The author presents studies aimed to improve the quality of collected time-domain data by minimizing the effect of phase uncertainties using software compensation.Finally, the thesis focuses on MWI algorithms. A comparative analysis of several existing time-domain MWI algorithms is accomplished to identify their advantages and weaknesses. This analysis yields important lessons on algorithm development in the light of the specific challenges presented by the MWI of the breast tissue. The author presents two improved MWI algorithms that address the identified drawbacks of the existing algorithms. The performance of the new algorithms is evaluated with experimentally-recorded data sets." --

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: Contrast agents and heating agents have been proposed for microwave breast tumor imaging and treatment, respectively. The dielectric properties of the tumor are altered with contrast agents or heating agents that locally accumulate in the tumor. The resulting change in dielectric properties of the tumor has the potential to enhance the sensitivity of microwave imaging of breast tumors and increase the efficiency and selectivity of microwave thermal therapy of breast tumors. This dissertation addresses several key challenges in contrast-enhanced microwave imaging and treatment of breast tumors. Carbon nanotubes (CNTs) have been shown to enhance both the relative permittivity and effective conductivity of the host medium, and are promising as theranostic (integrated therapeutic and diagnostic) agents. Thus, our properties characterization work focuses on CNT dispersions. We performed in vitro microwave dielectric properties and heating response characterization of dispersions of CNTs treated by different functionalization methods and identified a CNT formulation that is very promising as a microwave theranostic agent. Stable dispersions of CNTs with concentrations up to 20 mg/ml are obtained with this formulation, and the enhanced microwave properties of these dispersions are extraordinary compared to the control. We also conducted in vivo dielectric properties characterization of mouse tumors with intra-tumoral injections of CNT dispersions and confirmed that the presence of CNTs increases the dielectric properties of the tumor. In parallel, we developed a contrast-enhanced microwave breast tumor imaging algorithm using sparse reconstruction methods. We demonstrated that this algorithm accurately localizes small tumors in 3D numerical breast phantoms. We also demonstrated the experimental feasibility of this method using physical breast phantoms. Lastly, we studied the sensitivity of the distorted Born iterative method (DBIM) to initial guesses and developed a straightforward method for computing a reliable initial guess. DBIM is an iterative algorithm for solving the microwave inverse scattering problem and is used to initialize the sparse reconstruction algorithm developed in this research.

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 2012-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast cancer is the most common cause of non-skin malignancy in women and a leading cause of female mortality. A potentially important strategy for reducing this menace is the detection at an early stage. However, conventional mammographic detection techniques have many drawbacks and often cause harm to patients. The invention of non-invasive and non-ionizing microwave technique, to reveal the internal structure of biological objects was a break through in the field of medical diagnostics. This book deals with the development of active microwave imaging techniques for breast cancer detection. 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 imaging with measured reflected signals and microwave tomographic imaging with measured scattered signals are addressed here.
