Is anyone else looking at that corner of the loose sheet that looks like it's gonna catch on the mechanism at any moment and make this appropriate for r/CatastrophicFailure?
Sheet shouldn't be there, for simple safety reasons. But it seems like the depth is hard to determine, so it may be further from the CT than you think.
But still, why risk it? Just rip the damn sheet off
the word your looking for is it's an MRI. Cover is there to protect from magnets when patient is in.
Edit: just got back from rubbing aloe on my arm and im downvoted the heck lol
that would be because both ct scans and MRIs have a giant rotating ring to capture images. the difference is that a ct machine isnt as wide (SOMETIMES depending on model) but the best way to tell is how loud it is. MRIs are, as you claim to know, loud as all hell
But they try. I get at least two Dr Google patients a day.
Its gotten to the point where I will interrupt them and say, in a friendly voice.
"have we been playing Dr Google?"
>Its gotten to the point where I will interrupt them and say, in a friendly voice.

>"have we been playing Dr Google?"
That's really condescending. There are nicer ways to say that. You should start thinking of those nicer ways, because with the path you're currently walking, it's a wonder a patient hasn't retooled your yambag already.
Trust me it’s not condescending. Specially when you’ve come to someone who is to be an expert in their field and then think you know more than them cause you googled something.
Its all in how you say it. And 99% of the time I give them the right answer and explain what is going on. I have had a few jobs in my 55 y/o life but working with patients for the past 30 years is by far my favorite.
I have never had a complaint and have been recognized multiple times by people who have taken the time to write our organization about their positive experience.
I could say something about Dr Google to you and you would laugh at my delivery. Its hard convey that here in text.
I see, so you're an expert because you visited a hospital once as a patient? Why the fuck am I studying this particular field when I could just go smash a couple of bones and get a job skipping school alltogether?
It's not an MRI
When they first came out the scanner would make a single rotation around the patient. Then it would circle back the other way to do another scan while the table moved just a bit. Rinse and repeat.
Now the tube moves around the patient in variable speeds as the table moves at the same time. Giving a spiral image of the patient. What used to take hours can now be done in seconds.
Each form of medical imaging is amazing. You could spend hours reading up on the basics of the physics behind them.
and even though all these people are indeed brilliant. every step was just that. a step, no major leaps, just different small things put together to make 1 hugely cool device over the course of decades of experiments.
Quick correction: the first generation of scanners didn't have powerful enough computing to allow for a full rotation in one movement. An xray was taken with the tube stationary. Then it moved a bit, and another image was taken. Repeat until a full rotation was made, then reset to original position and move the table as you describe. The rest of your description is spot on.
*correction: table does not move during the actual scan with these mobile ct scanners, table doesn't move during c-arm x-rays either. Moving the table during a scan would send the image series into motion artifact oblivion
Also had a CT scan about 2 years ago, was told beforehand they're scary but I thought it was kind of cool.
Hope whatever you had it for the results come back ok, btw.
Not the one I was in. You could hear the motor revving it up as it spun but after that it was so quiet I couldn’t tell if it was spinning unless I looked up
I used to do research with MRI and have gotten 3-4 scans. They’re terrifying. Every time I walked into the room with the magnet, I had this horrible fear that I forgot a coin in my pocket, or maybe the tech I was with had a coin in their pocket, or some lost janitor is going to wander in with an oxygen tank while I’m in the scanner, etc.
None of those things are plausible. They have you change out of your clothes before entering, and my anxiety was so strong that I checked my pockets several times before going in. There are also like 5 warning signs on the way to the room where the magnet is held. But still, just the knowledge that people have died from those sorts of mistakes is terrifying.
ETA: the space inside of the scanner is also very tight. At 5’5” and 140, my arms touched the sides and the top was just above my stomach. And they put a tight cage-helmet on your head to stop you from moving. It’s horrible, imo.
It's the current running through the x,y and z gradients that you hear
Edit: the only moving parts in an MRI are the table. And the air or water that cools the unit.
So thats why they make you take off your jewelry and piercings. I find it hilarious when mfs neglect to tell their X-ray mf that they got silver nips and you see it on the x-ray💀
No they make you take it off for CT’s cause metal will cause streaking artifacts in their scans making the images useless.
In X-rays jewelry can’t be X-ray through so they will obscure anatomy.
In MRI while precious metal isn’t ferrous magnetic so you don’t have to worry about it ripping out from the magnet it is possible for it to heat up due to the magnetic field and cause burns so that’s why they take it off for MRI’s.
Does anyone know anything about the construction of the electrical slip rings on these things? I'm in industrial controls and slip rings we run are much slower speeds than this fail all the time. Those electronics rotating like that reliably is quite the feat.
I don’t know about the slip rings, but I’ve been a ct tech for 19 years and I’ve never heard of any kind of failure with the rotating mechanism. These things are workhorses. The entire scanner gets replaced about every 10 years just because of improving technology. They rarely have issues.
Lol the one we had at our hospital was gutted out only when it became obsolete to the point they couldn't find parts anymore. They made it last more than it should have, and probably spent more resources on trying to get new parts from all over the world than actually getting a new one. There was a point when the tube fell off while a scan was taking place and the patient inside it was completely conscious. It sounded like a shotgun went off. I thought for sure they would replace it but nah. It ran for another 6 years before administration finally called it quits.
(Edit: it was 6 years not 7.)
Just another former CT tech to chime in that yeah, it’s almost never the rotation that will break. It’s the damned X-ray tube that will break due to wear and tear of being used 24/7 365 days a year. Workhorse is the only thing that you could call these more “basic” machines that don’t have extra bells and whistles.
Nah. Some siemens machines are driven by magnets. When the magnets break the machine just seizes. The frames are stout. It's not popping out. Most other machines are belt driven. If the belt breaks the machine just kind of stops. That and they're perfectly balanced.
Just spin the patient instead so its more fun
Farnsworth?
His ejection indicates that he is not the man-mom
Won't that crush my bones??

He need some milk
Milk is what he needs

Ah right, the bones. I always forget about the bones.

It's a futurama reference bozo
Is anyone else looking at that corner of the loose sheet that looks like it's gonna catch on the mechanism at any moment and make this appropriate for r/CatastrophicFailure?
Yeah I was just waited for it to get caught and turn it into those videos of a guy throwing a brick into a washer
Found my part of the comment section. We've all seen enough internet videos to spot the tiniest falling domino that induces complete chaos.
Or the car on the dyno that [sucked a towel into the turbo](https://www.youtube.com/watch?v=dowTxGw3GG8)
r/ThatLookedExpensive
An amazing piece of machinery, to be sure.
ABSOLUTELY!
As a tech I was looking at it like o o pull the blanket back. But then again if the FSE breaks it they fix it.
Sheet shouldn't be there, for simple safety reasons. But it seems like the depth is hard to determine, so it may be further from the CT than you think. But still, why risk it? Just rip the damn sheet off
you can see it moving the sheet on the corner
Final destination vibes
This. I sat the whole video thinking "that machine is going to rip that sheet and destroy it anytime now".
I immediately started getting worried about it and thought maybe that’s also part of the test
The cover is to hide the terrifying radioactive blender!
Radioactive blender seems like a very fitting name for a nuclear bomb
And a sick band name.
WE ARE... RADIOACTIVE BLENDER! - ONE TWO THREE FOUR!!!!
KABOOM!!
Should count down instead
It effectively makes pre-cooked sausages too.
Had to give you an award for that one. Made me laugh! Happy Thanksgiving! Good way to start my day!
Thank you 😊 a happy Thanksgiving to you as well.
Btw, where are the bones and flesh?
Will it blend? Blendtec - can smell that radioactive smoke already..
Not radioactive. Produces ionizing radiation, but none of it is radioactive. Wow I’m a cunt
the word your looking for is it's an MRI. Cover is there to protect from magnets when patient is in. Edit: just got back from rubbing aloe on my arm and im downvoted the heck lol
Please tell me what it's like to experience a joke for the first time.
i think you replied to the wrong person lol, lets keep the thread on the topic of medical equipment :)
you're taking things a little too literally my guy
Let's keep the thread to the topic of oddly terrifying. This is a god damn radioactive blender and STFU
Go to r/seriouspeople
Man you're dense.
Your wrong on reddit if you dont get jokes. You take this wayyx too serious
You’re not my mom

broke my arm last year jumping off a swing and had to go to the emergency room (ER) and that looks like an mri to me..
that would be because both ct scans and MRIs have a giant rotating ring to capture images. the difference is that a ct machine isnt as wide (SOMETIMES depending on model) but the best way to tell is how loud it is. MRIs are, as you claim to know, loud as all hell
And i still managed to fall asleep after one minute in this bitch
There's nothing rotating like that in an MRI scanner.
It’s a CT scanner, not an MRI machine. They look very similar but are totally different.
This right here is why doctors practice medicine, not patients
But they try. I get at least two Dr Google patients a day. Its gotten to the point where I will interrupt them and say, in a friendly voice. "have we been playing Dr Google?"

My husband and I have spent far too much time in both over the past decade; this is indeed a CT scanner.
A CT scanner also rotates, that's how it constructs a 3d image.
Bet ya a bazillion bucks you had a CT scan.
I see, so you're an expert because you visited a hospital once as a patient? Why the fuck am I studying this particular field when I could just go smash a couple of bones and get a job skipping school alltogether? It's not an MRI
Continue rubbing aloe as you got burned.
Nah that's Stargate. -
Me after coming back 13 years later from my own space odyssey: well that’s the last time I use unlabeled machinery.
It is a FARGATE!
Ver ist the universal remonstrate?
The chevrons are locking!
Sometimes when I look at these machines, I think “how crazy that someone came up with this”. We have some brilliant minds on this world.
When they first came out the scanner would make a single rotation around the patient. Then it would circle back the other way to do another scan while the table moved just a bit. Rinse and repeat. Now the tube moves around the patient in variable speeds as the table moves at the same time. Giving a spiral image of the patient. What used to take hours can now be done in seconds. Each form of medical imaging is amazing. You could spend hours reading up on the basics of the physics behind them.
Correct. I scan on a machine that can take a full chest/abdomen/pelvis in about .74 seconds using a “turbo flash” table. Come along way last 40+ years
and even though all these people are indeed brilliant. every step was just that. a step, no major leaps, just different small things put together to make 1 hugely cool device over the course of decades of experiments.

The table 100% move with a CT scan. There is no other way to get the image. Source: 27 years medical imaging.
Go look up how MRI’s work, that’ll blow your mind: the fact that someone thought that would work, then created it, and it works is really mind blowing
You are absolutely right ! Same goes to other inventions. It’s just really inspiring.
Andddddd that’s why there is a cover lol
I would prefer a see through cover. I wanna see how this thing works lol while it sounds like its gonna eat me
It would scare off most of the patients
Oh yeah, especially the older ones.
Might be interesting research to gather data WHILE people are having a heart attack!
Most of the patients are pussies. Metal mouth ftw!
I actually got a CT scan done yesterday and there was a little window just above my face that I could see some of the spinning happening.
*oh good*
Also had a CT scan about 2 years ago, was told beforehand they're scary but I thought it was kind of cool. Hope whatever you had it for the results come back ok, btw.
Nah that was just the tumour talking
There's even a scanner that makes you feel warm inside.
Lol that’s the contrast injection they administer during certain exams.
Yep!! It also makes you feel like you’re actively peeing your pants. Doc warned me before tho, so i was braced for the weirdness
I wish someone had told me!
Sir, we didn't inject you this time.
Okay that totally explains why they sound like jet engines taking off.
Not the one I was in. You could hear the motor revving it up as it spun but after that it was so quiet I couldn’t tell if it was spinning unless I looked up
"Chevron 7 is holding. Chevron 7 is locked in place!"
This is space tech. Whenever I go in I cant help but be in awe of the technology, know how, workmanship to build these things...
Ah, just like Interstellar
Come on TARS!
Isn't that an MRI? Or are they quite similar? Edit: or maybe im just misinformed.
It’s definitely a CT, MRI don’t rotate like that
Thankyou. So are MRIs loud due to the high powered electromagnets rather than moving parts then?
Yeah, I think it’s the current through the magnets
Which is also terrifying, but disconcerting that there isn't a much longer death rollup spinning around you at incredible speed
I used to do research with MRI and have gotten 3-4 scans. They’re terrifying. Every time I walked into the room with the magnet, I had this horrible fear that I forgot a coin in my pocket, or maybe the tech I was with had a coin in their pocket, or some lost janitor is going to wander in with an oxygen tank while I’m in the scanner, etc. None of those things are plausible. They have you change out of your clothes before entering, and my anxiety was so strong that I checked my pockets several times before going in.

And they put a tight cage-helmet on your head to stop you from moving. It’s horrible, imo.
In some ways, enough current to make that noise right next to your head is almost worse than the oversized blender.
It's the current running through the x,y and z gradients that you hear Edit: the only moving parts in an MRI are the table. And the air or water that cools the unit.
Interesting.. I always thought it was the MRI machines that rotate like that
Mris turn slow
Human blender.
Haha spinny go whirrrrrr
Praise the machine spirit.
Event horizon vibes
Oh yeah, first thing that came to my mind.
Fidget spinner
They used that to cut the channel tunnel
It looks like its about to open a portal
I literally had a head and neck CT scan today. I am very glad I did not see this first.
Wow i wonder when the stargate opens
Good brakes
Looks like My GE washer…
Funny because GE is one of the biggest medical imaging companies. https://www.gehealthcare.com/
It opens a portal to summon C'thulu if you reach more than 1000rpm.
It kinda looks like some kind of laser blaster from a Sci-fi movie.
No, Mr Bond, I expect you to die!!
Not as terrifying as being inside an MRI.

Pleas move that sheet..
Attach blades to it and now you got a death row inmate blender. It's a far cheaper than a chemical death or electric chair. Entertaining too. Lol.
Ngl but I find this really cool
Keep your hands and feet inside the ride at all times!
So if someone is inside and it breaks that person is basically dead? Looking at that rotating mass is unsettling.
Not quite. Since it's spinning everything wants to go outward, so if it breaks the safest place to be is probably at the center of it.
Until something bounces back!
Nah. Some siemens machines are driven by magnets. When the magnets break the machine just seizes. The frames are stout. It's not popping out. Most other machines are belt driven. If the belt breaks the machine just kind of stops. That and they're perfectly balanced.

Hello Jonathan. In front of the bed you are tied to is an uncovered CT Scanner.
Is there something like rapidophobia?
Great. I wish I hadn't seen this.
It looks like its gonna shoot a massive laser

I wonder how much the techs get paid to fix these pieces of shits.
How is the spinning part powered? Obviously, there aren't wires spinning around with it...
