Author:

Andrew Karellas , PhD, Maryellen L. Giger, PhD, Joseph Yuan-Chieh Lo, Emil Y. Sidky, and Steven P. Poplack

Code: RC221

Objectives:

This session includes three sections.  The first is : Physics Optimization for Clinical Translation, in which attendees will understand how radiographic technique affects dose and image quality of breast tomosynthesis. Attendees will also identify issues with breast compression for tomosynthesis versus mammography. They will learn about other physics research affecting the clinical translation of breast tomosynthesis, including scatter and noise compensation, image display, and computer-aided detection. The second section is Breast Tomosynthesis: Update on Image Acquisition and Reconstruction Techniques, which discusses the properties of Digital breast tomosynthesis (DBT) volume images which will be presented in the context of X-ray projection imaging and Computed Tomography (CT). Attendees will learn the impact of various DBT scanner configurations on the volume image will be discussed. This section highlights the role of image reconstruction in the overall data flow for DBT scanners. Attendees will learn about various algorithms for image reconstruction will be presented, and their impact on image quality will be sketched. The third section is Clinical Aspects of Breast Tomosynthesis, which discusses the likely areas of clinical application of digital breast tomosynthesis. Attendees will learn the potential advantages and limitations of digital breast tomosynthesis. They will also become familiar with clinical research/literature on digital breast tomosynthesis.
