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
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.
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.
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.
