- Who builds it
- We're LunarWerx LLC, a for-profit company. The code and the model cards are public.
- What's next
- We plan to train bigger research models on rented computer time.
Checked on scans the models never trained on.
115
body structures outlined on CT
Checked on 89 CT scans kept out of training. Each structure is in at least 10 of them.
25,596
chest X-rays used for testing
NIH's official test list. None were used in training.
4,067
children's wrist X-rays used for testing
From the GRAZPEDWRI-DX test set. Only pictures with a clear label are counted.
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 coloured 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 colour.
Research models
-
One view Mammogram
It opens like any other X-ray, with zoom and brightness.

Support the research
Help train bigger research models.
Your support pays for rented computer time to train the research models. Today they train on one home graphics card. A data-centre GPU, the A100 80GB, rents for $1.59 an hour.

Your scan stays on your device.
Nothing is uploaded when you open a scan. Your browser reads the pictures on this device, and they're gone when you close the tab. If you ever donate a scan to the research, you see everything first, and your browser removes anything that could identify you.
