CENTER FOR VIRTUAL IMAGING TRIALS
A virtual platform for evaluating medical imaging technologies from design to use
CVIT is a National Center for Biomedical Imaging and Bioengineering supported by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) and operated at Duke University.
Truth-based CT Reconstruction Challenge
In partnership with the American Association of Physicists in Medicine (AAPM), the Center for Virtual Imaging Trials (CVIT) is offering the TrueCT reconstruction challenge.
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.
