Scans we cover
X-ray, CT, MRI and mammogram.
Each kind of scan opens in the viewer, and each has open research models trained on public data.
-
Chest Wrist Spine X-ray
The viewer opens single pictures and series, with zoom and brightness.
-
Organs Lungs CT
Scroll through the slices, change the brightness window and zoom. The 3D sample shows the organs and bones as coloured shapes.
Research models
-
Lower spine MRI
Scroll through the slices of a spine MRI, with zoom and brightness. Discs and vertebrae can be coloured by name.
Research models
-
One view Mammogram
Opens the picture for zoom and brightness, like any other X-ray style picture.

One result from each research model.
Research results on public test data. They say nothing about your own scan.
