CONRAD is a state-of-the-art software platform with extensive documentation. It is based on platform-independent technologies. Special libraries offer access to hardware acceleration such as CUDA and OpenCL. There is an easy interface for parallel processing. The software package includes different simulation tools that are able to generate 4-D projection and volume data and respective vector motion fields. Well known reconstruction algorithms such as FBP, DBP, and ART are included. All algorithms in the package are referenced to a scientific source.

The software package is developed at the Radiological Sciences Laboratory, Stanford University and the Pattern Recognition Lab of the University of Erlangen-Nuremberg.

The software allows also to render various phantoms like:
