RESOURCES
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.
Software
CVIT Observer Models
Toolbox for mathematical observer model calculations, designed to produce image quality figures of merit from simulated image data from CVIT.Pysarfe Radiomics Pipeline
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 v1.0
DukeSim v1.0 is a GPU-based CT simulator that generates CT projection images of a given voxelized computational phantom.XCAT Phantom Program
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).XCAT Brain Phantom
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.Surface CT Projector
CT projector that generates x-ray projections directly from surface definitions of a given phantom without using voxelization.MOBY/ROBY Phantoms
Highly detailed anatomies for a laboratory mouse (MOBY) or laboratory rat (ROBY) with ~1400 defined structures.
Data
Database for Benchmarking Organ Dose Estimates and Uncertainties in CT
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.XCAT Anatomy Files
Library of anatomy files that work with the XCAT 2 program or can be used with other programs that work with 3D CAD geometries.
