In the past 20 years breast cancer has remained the number one cancer affecting women in Hong Kong. Mammogram remains the first line screening or diagnostic tool, and the most commonly performed procedure for breast cancer detection. Tomosynthesis, or digital breast tomosynthesis (DBT) was a new technology invented a few years ago aiming to reduce the problem of overlapping shadows in conventional mammogram. It is widely used in western countries, while there is only limited availability in Hong Kong. The objectives of this paper are to compare performance of conventional mammography with breast tomosynthesis, and see whether the new imaging modality could replace the conventional one. Methods: A literature search was performed using PubMed to locate all relevant articles that compare the diagnostic accuracy of breast tomosynthesis with mammography from 2010 up to December 2014. Systematic review of 19 studies was performed. Findings: Most studies showed that combined use of breast tomosynthesis and mammography significantly reduced recall rate, as a screening tool. Only one study compared breast tomosynthesis alone with 2D mammography as a screening tool, which also showed significant reduction in recall rate. Concerning cancer detection rate, the results appeared controversial, some studies showed increase cancer detection rate, while others showed no significant difference. Concerning diagnostic accuracy, most studies showed improvement in diagnostic accuracy, in terms of sensitivity and specificity. Conclusions: Breast tomosynethesis appears to be a promising screening tool to detect breast cancer, in terms of cancer detection rate and recall rate. In countries where there is population screening, breast tomosynthesis may be a good substitute for conventional mammography, but it is expected that more studies may be required for such use to be commonly practiced. In Hong Kong, where there is no population screening programme, there may not be urge for introducing breast tomosynthesis to be used as screening tool. However, in public hospital, where most cases are referred cases and under specialist care, use of complimentary breast tomosynthesis is still controvertial.

Book Description :

An innovative, three-dimensional x-ray imaging technique that enhances projection radiography by adding depth resolution, Tomosynthesis Imaging explores tomosynthesis, an emerging limited-angle tomographic imaging technology that is being considered for use in a range of clinical applications, and is currently being used for breast cancer screening and diagnosis. While conventional mammography has been very successful in reducing breast cancer mortality, it is not perfect. A major limitation of mammography is that the recorded image represents the superposition of complex three-dimensional structures in the breast onto a two-dimensional plane, making detection and diagnosis of breast cancer challenging. Tomosynthesis produces quasi-three-dimensional images that can significantly enhance the visualization of important diagnostic features. This book highlights the flexibility of tomosynthesis systems for new clinical applications, and provides a detailed discussion of the tomosynthesis acquisition process and the impact of physical factors. It explores such topics as acquisition parameters, system components, modeling, image reconstruction algorithms, and system evaluation. Provides in-depth coverage of system design considerations, as well as image reconstruction strategies Describes the current state of clinical applications of tomosynthesis, including imaging of the breast and chest, as well as its use in radiotherapy Illustrates the merits of tomosynthesis imaging and its potential clinical applications in imaging of the breast and chest, as well as for radiation therapy Divided into five sections, this text delves into the history and development of tomosynthesis. It introduces tomosynthesis imaging, discusses imaging system design considerations, and reviews image reconstruction algorithms that have been developed for tomosynthesis. It also describes system evaluation methodologies, emphasizes current clinical applications, and examines the future direction for tomosynthesis.

Book Description :

Breast cancer is the second most prevalent cancer, globally, with millions of new cases identified each year. Since the introduction of widespread screening for breast cancer, there has been a steady decline in breast cancer mortality. In order to reliably detect breast cancers, breast screening methods need to offer high spatial resolution, low dose, high patient throughput, and excellent low contrast detectability. Mammography has been the gold standard in breast cancer screening since it was introduced, however many new technologies have emerged recently that offer many additional benefits when compared with mammography. One such method, digital breast tomosynthesis (DBT) builds on existing equipment and techniques used in mammography by incorporating three dimensional (3D) information. Clinically available in the United States since 2011, the addition of DBT has been shown to improve both sensitivity and specificity for breast screening when compared with two dimensional (2D) mammography alone. However, due to the unique requirements of breast imaging, image reconstruction, processing, and analysis for DBT is quite challenging. In this dissertation, several research areas are explored with the overarching goal of improving DBT imaging in a clinical setting. First, a novel image reconstruction algorithm and implementation strategy are introduced for DBT. Second, a technique to assess and understand the anatomical noise in the breast with respect to these new reconstruction methods is described. Finally, a platform-agnostic post-processing technique to reduce image noise and potentially reduce dose for DBT exams is presented. The tools presented in this work have been found to improve through-plane spatial resolution, reduce anatomical clutter, and potentially enable significant dose reduction for DBT. These are all very important steps in providing effective and safe breast cancer screening in the future.

Digital Radiography has been ? rmly established in diagnostic radiology during the last decade. Because of the special requirements of high contrast and spatial resolution needed for roentgen mammography, it took some more time to develop digital m- mography as a routine radiological tool. Recent technological progress in detector and screen design as well as increased ex- rience with computer applications for image processing have now enabled Digital Mammography to become a mature modality that opens new perspectives for the diag- sis of breast diseases. The editors of this timely new volume Prof. Dr. U. Bick and Dr. F. Diekmann, both well-known international leaders in breast imaging, have for many years been very active in the frontiers of theoretical and translational clinical research, needed to bring digital mammography ? nally into the sphere of daily clinical radiology. I am very much indebted to the editors as well as to the other internationally rec- nized experts in the ? eld for their outstanding state of the art contributions to this v- ume. It is indeed an excellent handbook that covers in depth all aspects of Digital Mammography and thus further enriches our book series Medical Radiology. The highly informative text as well as the numerous well-chosen superb illustrations will enable certi? ed radiologists as well as radiologists in training to deepen their knowledge in modern breast imaging.

Book Description :

Digital breast tomosynthesis (DBT) strives to overcome the obstacles presented in conventional 2D mammography by taking multiple projections over a fixed angle and reconstructing volumetric data isolates overlying anatomy from in-plane structures and amplify the conspicuity of lesions. Temporal subtraction automates the process of comparative analysis by using two images taken sequentially and subtracting them in order to find temporal discrepancies. The purpose of this project is to determine the feasibility of using temporal subtraction on DBT phantom images to allow for easier and earlier detection of breast cancer than with either technique alone. The investigator acquired initial tomosynthesis images with the compressible and deformable breast phantom using materials to simulate the breast parenchyma. This was a first step to see if the physical breast phantom originally conceived in theory would work in practice. Unfortunately, the materials used for the breast tissues did not provide a realistic enough breast simulation. Further work must be done to find different materials to use for the physical breast phantom so that realistic images can be used for the observer study. The investigator found that a 3D computer simulated breast phantom needs to provide a realistic and accurate representation of the breast parenchyma in order to offer a compelling argument for the technique. This can be accomplished through either mathematical methods using geometrical primitives or voxelizations of real patient data. The investigator has decided to use an approach combining empirical breast CT data with subdivision surfaces (SD)and non-uniform rational b-splines (NURBS) in the future for the computer breast simulation.

Book Description :

Conventional 2D mammography was the most effective approach to detecting early stage breast cancer in the past decades of years. Tomosynthetic breast imaging is a potentially more valuable 3D technique for breast cancer detection. The limitations of current tomosynthesis systems include a longer scanning time than a conventional digital X-ray modality and a low spatial resolution due to the movement of the single X-ray source. Dr.Otto Zhou's group proposed the concept of stationary digital breast tomosynthesis (s-DBT) using a Carbon Nano-Tube (CNT) based X-ray source array. Instead of mechanically moving a single X-ray tube, s-DBT applies a stationary X-ray source array, which generates X-ray beams from different view angles by electronically activating the individual source prepositioned at the corresponding view angle, therefore eliminating the focal spot motion blurring from sources. The scanning speed is determined only by the detector readout time and the number of sources regardless of the angular coverage spans, such that the blur from patient's motion can be reduced due to the quick scan. S-DBT is potentially a promising modality to improve the early breast cancer detection by providing decent image quality with fast scan and low radiation dose. DBT system acquires a limited number of noisy 2D projections over a limited angular range and then mathematically reconstructs a 3D breast. 3D reconstruction is faced with the challenges of cone-beam and flat-panel geometry, highly incomplete sampling and huge reconstructed volume. In this research, we investigated several representative reconstruction methods such as Filtered backprojection method (FBP), Simultaneous algebraic reconstruction technique (SART) and Maximum likelihood (ML). We also compared our proposed statistical iterative reconstruction (IR) with particular prior and computational technique to these representative methods. Of all available reconstruction methods in this research, our proposed statistical IR appears particularly promising since it provides the flexibility of accurate physical noise modeling and geometric system description. In the following chapters, we present multiple key techniques of statistical IR to tomosynthesis imaging data to demonstrate significant image quality improvement over conventional techniques. These techniques include the physical modeling with a local voxel-pair based prior with the flexibility in its parameters to fine-tune image quality, the pre-computed parameter κ incorporated with the prior to remove the data dependence and to achieve a predictable resolution property, an effective ray-driven technique to compute the forward and backprojection and an over-sampled ray-driven method to perform high resolution reconstruction with a practical region of interest (ROI) technique. In addition, to solve the estimation problem with a fast computation, we also present a semi-quantitative method to optimize the relaxation parameter in a relaxed order-subsets framework and an optimization transfer based algorithm framework which potentially allows less iterations to achieve an acceptable convergence. The phantom data is acquired with the s-DBT prototype system to assess the performance of these particular techniques and compare our proposed method to those representatives. The value of IR is demonstrated in improving the detectability of low contrast and tiny micro-calcification, in reducing cross plane artifacts, in improving resolution and lowering noise in reconstructed images. In particular, noise power spectrum analysis (NPS) indicates a superior noise spectral property of our proposed statistical IR, especially in the high frequency range. With the decent noise property, statistical IR also provides a remarkable reconstruction MTF in general and in different areas within a focus plane. Although computational load remains a significant challenge for practical development, combined with the advancing computational techniques such as graphic computing, the superior image quality provided by statistical IR will be realized to benefit the diagnostics in real clinical applications.

Book Description :

Digital breast tomosynthesis (DBT) is a new technology for breast cancer screening that promises to supersede mammography to become the standard for breast imaging. DBT involves taking multiple images to synthesize a new image that represents a slice through the breast volume. The primary advantage of DBT is that it can reduce the amount of overlapping anatomy in the data, leading to improved visualization of potentially-cancerous findings. The difficulty in DBT is quantifying the advantages of the technology and determining the optimal conditions for its clinical use. This study describes a virtual trial framework for assessing and optimizing DBT technology for the specific task of detecting small, low-contrast masses in the breast. It addresses each component of the imaging chain to some degree, from the patients/phantoms to the imaging hardware to the model observers used to measure signal detectability. The main focus, however, is on quantifying tradeoffs between three key parameters that affect image quality: (1) scan angle, (2) number of projections, and (3) exposure.

This volume (5116) of Springer’s Lecture Notes in Computer Science contains the th proceedings of the 9 International Workshop on Digital Mammography (IWDM) which was held July 20 – 23, 2008 in Tucson, AZ in the USA. The IWDM meetings traditionally bring together a diverse set of researchers (physicists, mathematicians, computer scientists, engineers), clinicians (radiologists, surgeons) and representatives of industry, who are jointly committed to developing technologies to support clinicians in the early detection and subsequent patient management of breast cancer. The IWDM conference series was initiated at a 1993 meeting of the SPIE Medical Imaging Symposium in San Jose, CA, with subsequent meetings hosted every two years at sites around the world. Previous meetings were held in York, England; Chicago, IL USA; Nijmegen, Netherlands; Toronto, Canada; Bremen, Germany; Durham, NC USA and Manchester, UK. th The 9 IWDM meeting was attended by a very international group of participants, and during the two and one-half days of scientific sessions there were 70 oral presentations, 34 posters and 3 keynote addresses. The three keynote speakers discussed some of the “hot” topics in breast imaging today. Karen Lindfors spoke on “Dedicated Breast CT: Initial Clinical Experiences. ” Elizabeth Rafferty asked the question is “Breast Tomosynthesis: Ready for Prime Time?” Finally, Martin Tornai discussed “3D Multi-Modality Molecular Breast Imaging.
