At the hospital where I work we have three full body General Electric MRI
machines and one Philips extremity MRI scanner. The machines themselves
don't run Windows, what they run is proprietary. SGI Workstations form the
front end here. The SGI's control the machines and do the primary
rendering. The attending radiologist views the scans as they occur and
selects the images that best indicate the presence or the absence whatever
was suspected. The physicians have three fundamental ways of viewing the
MRI scans. One is where the image is transferred to a transparency so that
it can be viewed on a typical back lit x-ray board. The other is for the
physician to view the stored images using SGI workstations set up in the
viewing library. The final method is via CD-ROM, which surprisingly in
this day and age is the least favourite method.

The machines use liquid helium for cooling the superconducting
electromagnet. Each machine also has it's own little chilled water system
for cooling the computer room for each machine. Room temperature is
critical because as the room warms up the RF amplifiers start to drift
wildly. Normally the room is at 19C, if the room temperature rises to 21C
an alarm goes off and if the room hits a stifling 24C the machine is shut
down.
