Preliminary Clinical Experience with a Combined Automated Breast Ultrasound and Digital Breast Tomosynthesis System

摘要

We analyze the performance of a mammographically-configured, automated breast ultrasound (McABUS) scanner combined with a digital breast tomosynthesis (DBT) system. The GE Invenia ultrasound system was modified for integration with GE DBT systems. The ultrasound and DBT imaging were performed in the same mammographic compression. Our small preliminary study included thirteen cases, six of which contained invasive cancers. From analysis of these cases, current limitations and corresponding potential improvements of the system were determined. A registration analysis was performed to compare the ease of McABUS to DBT registration for this system with that of two systems designed previously. It was observed that, in comparison to data from an earlier study, the McABUS to DBT registration alignment errors for both this system and for a previously built combined system were smaller than for a previously built standalone McABUS system.
