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.
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.
Recently Shared Software
- DukeSim GUI v1.0 is a webpage-based graphical user interface (GUI) to run the DukeSim CT simulator. The GUI allows users to select phantom models, scanner models, and imaging parameters to generate simulated CT images.
- Novel hybrid Transformer-ConvNet model designed for 3D medical image registration.
Recently Shared Data
- Library of dose coefficients for organ dosimetry in tomosynthesis imaging of adults and pediatrics across diverse protocols.
- Anatomically variable chest and abdomen phantoms, each based on CT data and modeling either COPD or lung or liver abnormalities.
