Putting resources into the hands of scientists, developers, and clinicians
To encourage innovation through the broad engagement of the biomedical community, CVIT shares user-friendly, well-documented, and easily accessible resources for virtual trials in medical imaging.
These resources, continuously updated, include virtual human models, the formation of digital twins, simulations of varying pathologies, simulation of imaging processes, and modeling of human and machine reading of virtual data.
- Novel hybrid Transformer-ConvNet model designed for 3D medical image registration.
- Toolbox for mathematical observer model calculations, designed to produce image quality figures of merit from simulated image data from CVIT.
- Pipeline includes eleven unsupervised binary segmentation methods and a feature extraction module to calculate various radiomics features for an image and its binary segmentation pair.
- DukeSim v1.1 is a GPU-based CT simulator that generates CT projection images of a given voxelized computational phantom.
- Highly detailed male and female anatomies for subjects that are 50th percentile in terms of height/weight and organ volumes (thousands of defined structures including muscles and blood vessels).
- Highly detailed anatomy for the human brain, including ~100 structures and vessels. The program will generate voxelized versions of the brain at any user-defined resolution.
- CT projector that generates x-ray projections directly from surface definitions of a given phantom without using voxelization.
- Highly detailed anatomies for a laboratory mouse (MOBY) or laboratory rat (ROBY) with ~1400 defined structures.
- 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.
- Large database of chest CT scans from unique patients. Each CT volume is annotated with a matrix of 84 abnormality labels x 52 location labels.
- Anatomically realistic spatiotemporal maps of optical absorption coefficient and photoacoustically induced pressure distribution for virtual imaging studies of dynamic photoacoustic tomography of small animal models.
- Synthesized multimodal images (T1-weighted MRI, CT, and cone beam CT) as ground truth for image segmentation and registration.
- CT patient images and associated verified Monte Carlo based estimates of organ doses that may be used for benchmarking different organ dose estimation techniques against a reference standard.
- Library of anatomy files that work with the XCAT 2 program or can be used with other programs that work with 3D CAD geometries.
