What do I need - physics experiment

Hi all, forgive my ignorance of anything, I'm physics major about to begin an experimental project for my thesis, need help understanding what it is I'm even asking for / What parts I would need to build.

The project: using a 3d medical imaging system with a resolution of 10microns, hoping to scan phantoms (synthetic tissue samples) under induced motion. (Ie I'm trying to create conditions similar to what would be experienced if this machine was imaging living people, who breathe and move during scans).

I need to construct/find some form of vibrational platform, that can move up and down in (ideally) micrometer increments, at less than 0.1 Hz (people breathe ~10 times a minute).

I don't have the language to even describe what I need. Can anyone translate this to something I can write in an equipment request form?

Tldr, small vibrational platform that can move up and down +/- 0.01mm once every ~6 seconds.
