That might work.  X-rays don't really care whether they're imaging a
solid, liquid, gas, or superheated plasma.  The trick would be to apply
all of the energy before the resulting superheated plasma has time to
spread out by so much as our sub-micron resolution limit.  An x-ray
pulse of one nanosecond or less ought to do it.

I've seen this discussed before.  I don't recall if it was on this list.

Good luck finding volunteers.  Personally, I'll wait for the non-
destructive backup.
