This book was released on 2007 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this proposal is to fully automate and optimize the performance of a 3-D dedicated emission mammotomography system for enhanced semi-automated clinical testing. A retrospective study of 103 clinical MRI uncompressed breast scans was conducted to create surface renderings of the uncompressed breasts and analyze how to adapt existing acquisition orbits for varying breast shapes. Laser ribbon ranging sensors and associated hardware to fully automate the radius of rotation were acquired and tested. An observer based 3D contrast-detail study was performed in an effort to evaluate the limits of object detectability for the dedicated CZT-based SPECT mammotomography imaging system under various imaging conditions. Other aspects of the training program were also initiated including clinical shadowing in the mammography, nuclear medicine, and breast oncology divisions at Duke University.

This book was released on 2009 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this research is to optimize the development of a combined dual-modality single photon emission computed tomography (SPECT) and x-ray computed mammotomography (CmT) system for the earlier detection and staging of breast cancer, improving surgical biopsy guidance, and the monitoring of patient therapy response. It is believed that co-registered acquisition of emission (nuclear) and transmission (x-ray) data using both 3D imaging modalities in a common field of view may aid to accurately localize the radioactive uptake of a tumor in the emission image by using anatomical structure from the transmission image. In this second year, the radiation dose absorbed by the uncompressed breast during a regular tomographic scan using is extensively quantified using the developed tomographic system. New concept designs for the next generation 3D breast CmT system are also developed, in addition to new tomographic trajectories designed to overcome limitations in the ability of the developed CmT system to view the chest wall of the prone patient. In addition to the technical work, other aspects of the training program were also completed, including site visits to a major medical imaging company, the presentation of the research at scientific conferences, and the ongoing submission of a manuscript to a major peer reviewed journal. Finally, the doctoral thesis arising from this research was written and successfully defended by the author.
Download or read book Development and Characterization of Novel Volumetric Acquisition Orbits With an Application Specific Emission Tomograph for Improved Breast Cancer Detection written by and published by . This book was released on 2005 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this work is to develop, implement, and evaluate novel three-dimensional acquisition orbits used in conjunction with a dedicated emission mammotomography system, to be used as a potential secondary diagnostic tool. This novel nuclear medicine based molecular imaging technique utilizes camera trajectories that sample a pendant, uncompressed breast, which are evaluated with respect to various breast shapes and sizes. Phantom measurements have demonstrated that lesions near the chest wall can be visualized for both large and small sized breasts, and furthermore, that axillary imaging is possible even with minimal system tilt. The use of additional bed shielding, simulated here with a lead sheet, was also investigated. Preliminary results suggest the lead shield may hinder lesion detectability. Future work includes the addition of a patient bed, which is expected to further complicate positioning, and which may or may not include lead lining pending further studies.

Download or read book Design Implementation and Characterization of a Dedicated Breast Computed MammoTomography System for Enhanced Lesion Imaging written by and published by . This book was released on 2008 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this work was to design, implement, and characterize a novel dedicated mammotomography system for enhanced lesion detection. This novel system allows fully 3-D imaging of a pendant, uncompressed breast using novel 3-D complex orbit capabilities. A prototype system has been designed, developed, and extensively characterized with a number of figures of merit including SNR, dose efficiency, and contrast sensitivity. Results indicate the potential for sub dual-view dose uncompressed breast imaging. Observer studies have been performed to determine the lower limits of detectibility. Patient bed optimization has also been performed as well as system/bed positioning and tilt angles for optimal chest wall imaging and patient comfort. The outcome of this project is a fully functioning 3D dedicated breast imaging system ready for initial patient studies. In addition, the training provided by this grant has allowed the PI to continue on with further research and development of this system through SBIR and North Carolina state funding with the goal of commercialization.

Book excerpt: 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.

Download or read book Digital Breast Tomosynthesis written by Alberto Tagliafico and published by Springer. This book was released on 2016-05-03 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive description of the screening and clinical applications of digital breast tomosynthesis (DBT) and offers straightforward, clear guidance on use of the technique. Informative clinical cases are presented to illustrate how to take advantage of DBT in clinical practice. The importance of DBT as a diagnostic tool for both screening and diagnosis is increasing rapidly. DBT improves upon mammography by depicting breast tissue on a video clip made of cross‐sectional images reconstructed in correspondence with their mammographic planes of acquisition. DBT results in markedly reduced summation of overlapping breast tissue and offers the potential to improve mammographic breast cancer surveillance and diagnosis. This book will be an excellent practical teaching guide for beginners and a useful reference for more experienced radiologists.
