This repository provides sample datasets for volume rendering. The voxelwise data is saved in the NIfTI format. All of these samples are open source. See specific folders for sources and individual licenses. This repository provides examples of the volumes that have beeen cropped and have had air removed, yielding much smaller file sizes (you can always go to the source repositories to get the full fat volumes).
- OpenSciVis provides a collection of classic volume rendering scans sampled from the Open Scientific Visualization Datasets.
- Prism includes clinical images from the PRISMDatabase showing a brain tumor and an arteriovenous malformation (AVM).
- iguana is a CT of a Dipsosaurus dorsalis from DigiMorph.
- seg3D provides a clinical MRI and CT scan from an individual with subdural grid electrodes from the Seg3DData repository.
- stroke provides brain-extracted MRI scans (T1, T2, FLAIR) of an individual with chronic stroke.
There are many terrific free tools for viewing volume data. Since they are free, consider downloading a few and using the best tool for the task at hand.
- DragonFly is not open source, but non-commercial licenses are granted free-of-charge.
- Drishti has powerful rendering abilities, though support for medical imaging formats is limited. Robert Asher provides YouTube videos describing the functions.
- InVesalius provides useful segmentation tools.
- MRIcroGL was used to generate the renderings shown here.
- Seg3D has powerful segmentation routines.
- Slicer is a flexible tool. The SlicerMorph workshops provide workshops for using this tool. Peter Falkingham provides a YouTube video showing how to import a file and prepare it for 3D printing.
- Anatomical Tracings of Lesions After Stroke provides T1 scans and lesion maps from hundreds of individuals with stroke.
- CrocBase provides DICOM images of crocodiles.
- DigiMorph provides living and extinct vertebrates and invertebrates.
- MorphoSource has around 13,000 open access biological specimens.
- The dcm2niix wiki provides many DICOM samples as well as links to other resources.
