Wikipedia has more details about the project and the donors, and high quality photos (warning, human cadaver cryosections): https://en.wikipedia.org/wiki/Visible_Human_Project

What the OP article notes, that Wikipedia doesn't, is that Susan Potter was imaged in layers just 63 microns thick, vs 300 for the earlier female donor, and 1000 microns for the male.

The information is there, although you need to follow a link:

> Potter's body was (…) sliced into 27,000 slices in 63-μm increments, individually scanned during a period of 60 working days. Because the technology used in the Visible Human project significantly improved since its launch in 1993, much more detail will be available in Potter's scans: images from the two previous donors were based on 1,000 μm sections for the male subject and 300 μm for the female subject.

Then again, I only meant that Wikipedia has some extra data - not that it has everything from the article (it doesn’t).

Oh wow! Years ago, this program was preloaded on our laptops in medical school. I remember the donor was incarcerated and decided to donate his body. It was really quite helpful for visualizing anatomy in cross section vs what we saw in anatomy lab. It was a standalone folder app and I have regretted not backing it up elsewhere.

What's eerie to think about is that they don't actually make "slices" in a physical sense. They just grind away a bit, take a photo, grind away a bit, take another photo. At the end the body is just dust.
