MRISim's free simulator renders real, openly licensed anatomy. The datasets below power that tool; the paid course is separate original teaching material. Attribution and the terms each dataset is used under are listed here.

Anatomical datasets

BrainWeb Simulated Brain DatabaseResearch / educational use

McGill University Brain Imaging Centre. brainweb.bic.mni.mcgill.ca ↗

The digital brain phantom behind the free simulator's brain anatomy, remapped to tissue classes for signal simulation. Used for research and educational purposes.

Romano et al. Zenodo 10534328 ↗ (DOI 10.5281/zenodo.10534328), licensed CC BY 4.0.

A 3D isotropic T2 knee study. The free simulator's Knee region is a derived work: bone, soft-tissue and texture fields built from the annotated masks and real intensity.

SPIDER Lumbar Spine DatasetCC BY 4.0

van der Graaf et al., "SPIDER: Lumbar spine segmentation in MR images." Zenodo 10159290 ↗, licensed CC BY 4.0.

A sagittal lumbar T2 study. The free simulator's Spine region is a derived work: vertebrae, discs and spinal canal segmented, with the real T2 as texture.

TotalSegmentator MRI DatasetOpen (Zenodo)

Publicly available on Zenodo; underlying images sourced from the Imaging Data Commons.

Body regions (Abdomen, Pelvis, Torso) in the desktop simulator, built from combined organ masks and real-MRI texture. Not included in the browser build.
