Abstract
Digital breast tomosynthesis (DBT) enables significantly higher cancer detection rates compared to full-field digital mammography (FFDM) without compromising the recall rate. However, regarding microcalcification assessment established tomosynthesis system concepts still tend to be inferior to FFDM. To further boost the clinical role of DBT in breast cancer screening and diagnosis, a system concept was developed that enables fast wide-angle DBT with the unique in-plane resolution capabilities known from FFDM. The concept comprises a novel x-ray tube concept that incorporates an adaptive focal spot position, fast flat-panel detector technology, and innovative algorithmic concepts for image reconstruction. We have built a DBT system that provides tomosynthesis image stacks and synthetic mammograms from 50° tomosynthesis scans realized in less than five seconds. In this contribution, we motivate the design of the system concept, present a physics characterization of its imaging performance, and outline the algorithmic concepts used for image processing. We conclude with illustrating the potential clinical impact by means of clinical case examples from first evaluations in Europe.
