Abstract:
In 2017, Dr. Maidment presented an early prototype of a next-generation digital breast tomosynthesis (DBT)
system being designed at the University of Pennsylvania. Today, the successor to that prototype is in clinical
trials. In this presentation, the design, validation, and preliminary clinical results of the system will be presented.
The system was designed using virtual clinical trials (VCTs) in which simulations of breast anatomy, image
acquisition, and image analysis were used to design a system that was optimized specifically to improve clinical
performance. This design was then built, and imaging performance was validated against the VCT simulation
through physics testing and physics simulations. Having passed this validation, we commenced two clinical trials.
The first is a clinical trial designed to demonstrate superiority of the system when compared to conventional
DBT systems. In the second trial, the system is being used in combination with a limited-angle breast PET
camera to produce high-resolution fused PET-DBT functional and anatomic images.
