Tomosynthesis-Improved Breast Cancer Screening and Diagnosis

Main Article Content

Andrew Smith, PhD

Abstract




Since its introduction in 2000, digital mammography has become an accepted standard of care in breast cancer screening and has paved the way for a new groundbreaking technology- breast tomosynthesis. With breast tomosynthesis, images of a breast are acquired at multiple angles during a short scan. The individual images are then reconstructed into a series of thin, high-resolution slices typically 1mm thick, which can be displayed individually or in a dynamic ciné mode. A tomosynthesis data set virtually elimi- nates detection challenges associated with overlapping structures in the breast, which is the primary drawback of conventional two dimensional (2D) mammography. Figure 1 illustrates the basic principle. As is known from standard computed tomography (CT) body imaging, three dimensional cross sectional slices often improve visibility through the reduction of superimposed structures.
