This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the study of three-dimensional near-infrared (NIR) imaging reconstruction using ultrasound localization for breast cancer detection and diagnosis. With the 3D NIR forward model for reflection geometry built and investigated, successful reconstruction of both absorption and scattering coefficients has been obtained and evaluated using both a phantom study and initial clinic data. In this work, we first introduce a dual mesh optical reconstruction method with depth correction using a priori ultrasound information. It can significantly improve the reconstructed absorption distributions in deeper target layers. Clinical results have shown improved correlation between reconstructed total hemoglobin concentrations and the histological micorvessel density counts. Next, a combined Tikhonov regularization and dual mesh scheme based on finite element method (FEM) is proposed to solve the inter-parameter cross talk between the scattering coefficient and absorption coefficient. In this approach, the optimal regularization factor is given by the standard L-curve. Different regularization factors have been assigned to the target region and non-target region to incorporate the priori target information from the co-registered ultrasound images. Both phantom experiments and clinic examples have shown that this new approach has the ability to reconstruct the absorption and diffusion coefficients simultaneously, and the reconstructed target absorption and diffusion maps have no depth dependence effect. Finally, a simple two-layer model is generated and studied to solve a clinical issue related to the chest wall, which is a mixture of bones and muscles. For small breasts, the chest wall appears within 2–3 cm distance from the skin surface. As a result, the simple one layer model is not accurate. Furthermore, for some cases, there is also an obvious chest wall mismatch between the reference site and lesion site. To solve this clinical issue, a simplified two-layer model is generated and a fitting method is adopted to estimate the optical properties of both layers. Then a correction method is applied to correct for the chest wall mismatch between the lesion site and reference site. With this scheme, phantom targets located on top of the chest wall phantom layer can be reconstructed with good contrast and resolution.

Available in PDF, EPUB and Kindle. Book excerpt: X-ray mammography screening is the current mainstay for early breast cancer detection. It has been proven to detect breast cancer at an earlier stage and to reduce the number of women dying from the disease. However, it has a number of limitations. These current limitations in early breast cancer detection technology are driving a surge of new technological developments, from modifications of x-ray mammography such as computer programs that can indicate suspicious areas, to newer methods of detection such as magnetic resonance imaging (MRI) or biochemical tests on breast fluids. To explore the merits and drawbacks of these new breast cancer detection techniques, the Institute of Medicine of the National Academy of Sciences convened a committee of experts. During its year of operation, the committee examined the peer-reviewed literature, consulted with other experts in the field, and held two public workshops. In addition to identifying promising new technologies for early detection, the committee explored potential barriers that might prevent the development of new detection methods and their common usage. Such barriers could include lack of funding from agencies that support research and lack of investment in the commercial sector; complicated, inconsistent, or unpredictable federal regulations; inadequate insurance reimbursement; and limited access to or unacceptability of breast cancer detection technology for women and their doctors. Based on the findings of their study, the committee prepared a report entitled Mammography and Beyond: Developing Technology for Early Detection of Breast Cancer, which was published in the spring of 2001. This is a non-technical summary of that report.

Download or read book Breast Cancer Diagnosis Using Ultrasound and Diffusive Light written by and published by . This book was released on 2001 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed a novel near-infrared optical technique with ultrasound localization. During the last year, we have made significant progress on using our technique to improve breast cancer diagnosis. Initial results with a group of biopsied patients have shown that early stage invasive cancers present two-fold greater total hemoglobin concentration than fibroadenomas and benign lesions. Initial results of advanced cancers have shown good correlation between cancer angiogenesis distributions imaged by the hybrid imaging technique and histological microvessel density counts. We believe our unique has a great potential to improve current practice on breast cancer diagnosis and monitor treatment responses of advanced cancers.

Download or read book Time-Resolved and Spectroscopic Three-Dimensional Optical Breast Tomography written by and published by . This book was released on 2009 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the research project, "Time-Resolved and Spectroscopic Three-Dimensional Optical Breast Tomography," was to develop a safe and affordable breast cancer detection modality that uses noninvasive near-infrared (NIR) light for imaging and diagnosing tumors in human breast with high resolution and specificity. In order to realize that goal three different approaches were developed. These are Optical Tomography using Independent Component Analysis (OPTICA), Round Trip Matrix (RTM) approach, and Center of Intensity Time Gated Imaging (CITGI). OPTICA is the most developed of these approaches. It has been demonstrated that OPTICA can detect, obtain the threedimensional location information and cross-section images of small absorbing, scattering, and fluorescent targets in model media, and tumor(s) in realistic model breast with considerable accuracy. Further accomplishments include development of a forward model for determining the backscattered polarized light intensity distribution, and initial development of a technique to determine scattering coefficient, absorption coefficient, and anisotropy factor (g) of breast tissue specimens. Besides detection and localization of tumors in breast, these results may have potential applications in optical biopsy, and lumpectomy. The graduate student supported by the project received his Ph. D., adding another scientist to the ongoing fight against breast cancer.

Book Synopsis Ultrasound-guided Optical Techniques for Cancer Diagnosis by : Atahar Kamal Mostafa
Download or read book Ultrasound-guided Optical Techniques for Cancer Diagnosis written by Atahar Kamal Mostafa and published by . This book was released on 2019 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, breast cancer is the most common cancer among women. In the United States alone, the American cancer society has estimated there will be 271,270 new breast cancer cases in 2019, and 42,260 lives will be lost to the disease. Ultrasound (US), mammography, and magnetic resonance imaging (MRI) are regularly used for breast cancer diagnosis and therapy monitoring. However, they sometimes fail to diagnose breast cancer effectively. These shortcomings have motivated researchers to explore new modalities. One of these modalities, diffuse optical tomography (DOT), utilizes near-infrared (NIR) light to reveal the optical properties of tissue. NIR-based DOT images the contrast between a suspected lesion's location and the background tissue, caused by the higher NIR absorption of the hemoglobin which characterizes tumors. The limitation of high light scattering inside tissue is minimized by using ultrasound image to find the tumor location.This thesis focuses on developing a compact, low-cost ultrasound guided diffuse optical tomography imaging system and on improving optical image reconstruction by extracting the tumor's location and size from co-registered ultrasound images. Several electronic components have been redesigned and optimized to save space and cost and to improve the user experience. In terms of software and algorithm development, manual extraction of tumor information from ultrasound images has been replaced by using a semi-automated ultrasound image segmentation algorithm that reduces the optical image reconstruction time and operator dependency. This system and algorithm have been validated with phantom and clinical data and have demonstrated their efficacy. An ongoing clinical trial will continue to gather more patient data to improve the robustness of the imaging algorithm.Another part of this research focuses on ovarian cancer diagnosis. Ovarian cancer is the most deadly of all gynecological cancers, with a less than 50% five-year survival rate. This cancer can evolve without any noticeable symptom, which makes it difficult to diagnose in an early stage. Although ultrasound-guided photoacoustic tomography (PAT) has demonstrated potential for early detection of ovarian cancer, clinical studies have been very limited due to the lack of robust PAT systems.In this research, we have customized a commercial ultrasound system to obtain real-time co-registered PAT and US images. This system was validated with several phantom studies before use in a clinical trial. PAT and US raw data from 30 ovarian cancer patients was used to extract spectral and statistical features for training and testing classifiers for automatic diagnosis. For some challenging cases, the region of interest selection was improved by reconstructing co-registered Doppler images. This study will be continued in order to obtain quantitative tissue properties using US-guided PAT.

Book Synopsis Breast Cancer Diagnosis by : Gerald S. Johnston
Download or read book Breast Cancer Diagnosis written by Gerald S. Johnston and published by Springer. This book was released on 1975-11 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breast carcinoma is a dreaded disease. The incidence of breast cancer, which appears to be increasing, is 1 in 1500 women with an annual death rate of 4,000 from this disease in the United States (1). It is a cancer which threatens its victims with mutilation as weIl as early death. Although response to therapy has not been good, improved methods for earlier and more complete diagnosis are providing hope for better results. When a woman presents herself for routine breast examination, what diagnostic procedures are indicated? If a breast mass is present, what diagnostic and therapeutic methods are employed? When the mass proves to be malignant, what then? Should biopsy and mastectomy be a combined procedure? Should a positive biopsy be followed by a complete diagnostic work-up before definitive therapy is undertaken? While some answers may seem obvious and others less obvious, common medical practices vary considerably in response to all of these situations. No easy formula exists. Each patient must be given individual consideration and her* treatment carefully planned to incorporate all the diagnostic findings. Experience to date indicates that some diagnostic and therapeutic procedures have established efficacy while others are not very helpful and still others need more evaluation before their usefulness can be . assessed fully. Traditionally, treatment of breast cancer has been surgical. Through the years poor results from surgery, along with acquisition of knowledge of the lymphatic spread of this malignancy, prompted more and more extensive surgical procedures.
