NB: tome in Microtome has the same root as the T in CAT scan: computer aided tomography. Which is to say, slimly-sliced cabbage^W X-ray scans.

It's also the tome as in book, more properly one volume of a multi-volume (or multi-part) set, though it now generally simply means any large book.

Incredible, love learning language facts like this.

Etymology is disturbingly addictive.

https://en.wikipedia.org/wiki/Tomography: `The word tomography is derived from Ancient Greek τόμος tomos, "slice, section" and γράφω graphō, "to write" or, in this context as well, "to describe."`
