Step through a sample CT with its organs and bones outlined and named by a research model. Or open your own CT, MRI or X-ray: it stays on this device.

Your scan can be DICOM files from a disc, a folder or a ZIP.
It's made for education and research, and it is not a medical device. Personal use and research are free, and companies buy a license.
The teal band is the sample CT's slice. Drag to turn the skeleton and tap a bone for its name.
Sample CT from TotalSegmentator (CC BY 4.0). Outlines drawn by our CT organ outliner, a research model. 3D skeleton from BodyParts3D, © The Database Center for Life Science, CC BY 4.0, with parts merged and simplified by LunarWerx.
We tested on scans the models never saw while they learned.
115
body structures scored on CT
Tested on 89 CT scans the model never saw while it learned. Each structure is in at least 10 of them.
25,596
chest X-rays used for testing
NIH's official test list. None of these X-rays were used to train the model.
4,067
children's wrist X-rays used for testing
From the GRAZPEDWRI-DX test set. We counted only X-rays with a clear label.
Scans we cover
X-ray, CT, MRI and mammogram.
Each kind opens in the viewer, and each has research models trained on public data.
-
Chest 
Wrist 
Spine X-ray
Open one picture or a whole set, then zoom in and adjust the brightness.
-
Organs 
Lungs CT
Step through every slice, with zoom and a brightness window. A 3D view shows the organs and bones as colored shapes.
Research models
-
Lower spine MRI
Spine MRI slices open the same way, with zoom and brightness. In this example, each disc and vertebra has its own color.
Research models
-
One view Mammogram
It opens like any other X-ray, with zoom and brightness.

- Who builds it
- We're LunarWerx LLC, a for-profit company. The code and the model cards are public.
- Who backs it
- The Future That Works Foundation backs it as a free way to learn about AI in medicine. The foundation's founder owns LunarWerx.
- What's next
- We plan to train bigger research models on rented computer time.
- How we keep track
- Every training run goes in the log above, with its hours and its date.
Support the research
