@stux @qotca also *many* results on google image search seem to be wrong. most results for "MRI without cover" that have visible part numbers are CT scanners...

@stux @qotca Ah. Should've thought a bit more about it... MRIs should not need to rotate (they don't have a reason to due to their completely different working principle as far as I know) so this most likely is a CT scanner

@qotca @jakob Luckily i have not! 😮

i should edit the toot to CT/MRI

I've had, maybe, 10.

They sure do spin. And they're loud. The techs give you headphones with your choice of music. And a warm blanket.

No. Metal. Either in, or outside, your body.

Still loud.

@qotca @stux loud yes. spinny not the one I've seen.

@qotca @stux @jakob after 20 years servicing CTs (and occasionally some MRI) y can promise you there isn’t a rotating part in an MRI. The sound you hear is just the vibration of the coils due to the magnetic field.

@qotca @stux I've seen one MRI in person doing it's thing and had multiple CT scans done.
The MRI did not spin or had any obvious clues to being spinny (like an audible spinup/spindown phase) while the CT had very obviously a rotating part inside

Jakob (Jack/Jackie) replied to DELETED

@qotca @stux there are even open MRI machines that aren't even "donut shaped"

@qotca @jakob @stux they do not spin.
Protons within hydrogen atoms spin in MR, but nothing in the MR gantry rotates. Certainly not around the Z axis.
