I doubt this is AI. This looks right for a micro-CT angiograph.

The blood vessels will have X-ray opaque dye injected, so they stand out on the CT. You can then set a threshold in the visualization software to filter out other tissue. The software then uses an algorithm to apply some shading to the surfaces of the unfiltered tissue to create a 3D effect.

The red colouring is a choice of the user, it just colours darker parts red and fades out to transparency.
