But if they died, then either because a disease destroyed their body, or because of age. If the body is destroyed or 'used', I see no way to get them back.
I think it would depend on how recently they died before being frozen, since the brain is really the only organ we can't replace.
Unless we are able sometime to implant only the brain in some kind of machine, but that's a tad futuristic
Scientists were able to transplant heads in the 50's, so I don't think its entirely futuristic, although I think it was only tried once more after that.
