A New Methodology

We oﬀer an eﬃcient methodology for evaluating imaging technologies and applications in silico using computational models simulating the patient, the imaging system, and the image reader.

These models comprise our three technology, research, and development (TR&D) endeavors, where we continue to provide realistic computational models of human anatomy (virtual patients), state-of-the-art CT scanners (virtual scanners), and clinically relevant image analysis (virtual readers).

The TR&Ds work synergistically to oﬀer comprehensive resources and essential training to partners through our various collaborative and service projects as well as training and dissemination eﬀorts.
