Applying computed tomography to breast cancer screening

Friday January 25, 2019
3:30 pm


 Presenter:  Professor John Boone, UC Davis
 Series:  Physics and Astronomy Colloquium
 Abstract:  John will discuss some very important NIH research he conducts applying computed tomography to breast cancer screening.

About 12.5% of women in the U.S. will be diagnosed with breast cancer during their lives. Currently, breast cancer screening is performed with mammography and tomosynthesis, but the breast imaging community is aware that better detection methods exist. A twenty-year program at UC Davis Medical Center has focused on the development of dedicated breast computed tomography (CT) systems to improve breast cancer detection and diagnosis. Four breast CT systems have been designed, fabricated in-house, and used in various clinical trials involving over 600 women. In this presentation, I will demonstrate the evolution of breast CT systems in the lab, with a technical discussion of fabrication and functionality, software integration and calibration, and image quality improvements. Breast CT images will be shown, illustrating the potential of these fully 3D images to improve breast cancer detection. A number of projects involving the analysis of these breast CT volume data sets will also be presented, showing surrogate metrics for breast imaging performance, comparisons of 2D imaging (mammography) with 3D breast CT using both computer and human observer studies, use of the CT image data for improved breast dosimetry, and use of these image data sets to further our understanding of breast glandular anatomy.
