I remember when the CAT scan equipment was so expensive that it was housed in tractor-trailer rigs and would be driven from Hospital to Hospital to do scans.

Now tinkerers over on HackADay make simple CAT scan equipment at home :-)

Actually that was a response to a GOVERNMENT ‘rule’.

The government, in its infinite stupidity, dictated that the hospitals could not buy a CAT Scan if there was one within , IIRC 200 miles. This was to ‘keep costs down’ or so they claimed at the time.

It actually drove costs up.

The ‘law’ was supported by GE, then the major manufacturer of CAT Scanners at the time.

Surprise, surprise, surprise...............

The mobile units were to get around that edict by saying the hospitals were renting the machines, not buying them...................
