TumorSim

TumorSim is a cross-platform simulation software that generates pathological ground truth from a healthy ground truth (e.g., the BrainWeb data). The software requires an input directory that describes a healthy anatomy (anatomical probabilities, mesh, diffusion tensor image, etc). Example output simulation images are available for download for validating various image analysis algorithms such as registration and segmentation algorithms.

The simulation method is described in the following paper:
