Some of this is already occurring. The company I work for makes mobile imaging solutions (CT, MRI, PET) that fit in the size of a shipping container and are often transported by semi-truck. There are hospital designs that leave bays for these trucks to pull into with a door on the side to get patients in and out on detachable tables. So a small hospital system that only has the money for a single CT or MRI scanner can move it from site to site in rotation to see patients instead of siting it at a single hospital and having to send patients further from home. Doing that on a larger scale would be the next step.
