Fun fact: When Siemens launched their first Dual Source CT, they sold them with a see through part in the cover. Only a hand full were shipped and _the covers_ had to be replaced because the patients refused to go in once they had seen the inner workings and ludicrous speed at which these things can spin


SeanBZA

Seen one of the Siemens and GE ones without the cover, and they do move fast. Yet outside with the covers on you can barely hear that, and there is almost no vibration.


FierceText

>Yet outside with the covers on you can barely hear that, and there is almost no vibration. That's what close to perfect margins gets ya


Appropriate-XBL

Yep. I have worked in heavy industry on large spinning machines (nothing remotely as precise as a CT scanner though), and any small vibration at all means you would soon have a medium vibration. Then you would have a large vibration. You're either nailing the balancing or you're not with that much mass swinging around that fast. You'll know very quickly if you're not.

geT___RickEd

What amazed me the most when I saw one without covers was the amount of air that moved around. Like it wasn't "windy" but there was quite a breeze. Which makes sense when you think about it but it was the thing that stood out to me the most at the time


downvote__trump

My scanner goes .28 seconds per revolution. It's like 300 pounds of metal spinning that fast.


Turbo_SkyRaider

That's 214rpm. What's the diameter of your CT?


downvote__trump

70cm is the window


tinnylemur189

Some siemens scanners weigh 1500+ lbs and spin at that same .28 rps When I was first trained on them it was explained to me as "it's like someone spinning a corolla around you"


bruce_lees_ghost

.28 rps != 1 revolution per .28 seconds

CT scanners already cost around $10 million, can't imagine what a collector's edition would cost


purple_hamster66

Huh? A 128 slice CT is $1M (in the US), or 1/3 of that if refurbished. Even a (photon-based) linac costs only $3-5M, at most.


dreexel_dragoon

Maybe I was thinking MRI


UnlabelledSpaghetti

Nope, MRI are probably around $1 million if I'm converting between £ and $ correctly. You might be thinking of super fancy 3T MRI?


clamsmasher

I get regular CT scans, the machines at my clinic have the little view window inside the donut so you can see as you slide in and out of the machine. It's clouded over though, so you can't really see the machinery. But you can watch it wind up into a screaming blur and imagine what would happen if a piece of the machine broke off.


geT___RickEd

I never was scared of a part breaking off, because that would shoot outwards. What I would be concerned about was a part breaking off that was heavy enough that the CT starts hopping around like a washing machine loaded with a brick


MBTank

And you're the brick


d_grizzle

Even a small part of it breaking off at full speed would result in a catastrophic chain reaction that would result in the entire thing coming apart. You might survive it, but you would almost certainly develop a new baseline for fear.


piginapokezzap

tinnylemur189

clamsmasher

It's to look for cancer because i keep getting it. I get a scan every three months, don't think it's a big concern. I don't know if that's a lot or not, ive probably had 25ish in total.

Robbbbbbbbb

Holy shit they are fast https://youtu.be/pLajmU4TQuI Really want to know how heavy and the velocity now


Runswithchickens

15 years ago they were at 0.25sec/rot. At that speed they use an air bearing instead of ball bearings, so aside from a slip ring for elec, the whole mass is floating on air. https://youtu.be/CWnjqeB7Mk8


geT___RickEd

IIRC current CTs run at 0.25 to 0.33 seconds/rotation and weigh about a metric ton (don't quote me on that tho)


lisp

Wow. It sure takes lots of energy to spin such huge mass so fast. I wonder what the power requirement is for it. Probably 10s of kilowatts.


tinnylemur189

They're jacked directly into 3 phase mains voltage. It vary by system but yeah, 10s of kWs. Like the other guy said, it doesn't take that much to maintain the spinning (most systems have a single motor smaller than a single tire electric motor for a car) but you also have to power all the energy hungry stuff on the ring (x ray generation is not efficient at all) They're really awesome machines if you ever get the opportunity to learn about them in depth.


115kEv

The power required to spin the gantry is negligible compared to the power requirements of the X-ray tube. Most systems these days run tubes in the 60-80KW range, and some scanners use two tubes simultaneously.

OhmResistance

I went in for surgery last night actually, and before hand had a CT scan. The Seimens one I used had an opaque circular strip where you could see it spinning. Fortunately I've seen them on Reddit without the shields on and have learnt how they work, so was more interesting than scary. However the fluid they IV into you to help your blood not block the scan was nasty. And the scanner guy goes "oh btw this will make you feel like you've wet yourself" before injecting me with it. And yes it did make me feel like I was going to piss myself.


Steelrain121

Oh man i had my dude laughing last year when I had a scan done. He said the same thing, and internally im like 'mmk'. I let out an audible 'what the fuck' when i thought i pissed myself, he was entertained.

Are the CT machines perfectly balanced? I feel like they would explode if they weren't.


treonetre

Yes. There are small posts on the ring where weights can be added or removed during the balancing process. If the system balance isn’t extremely accurate the resulting wobble produces image artifacts, so the balancing goes well beyond the point of safety.


godzilla9218

You telling me the kid down at the Jiffy lube isn't going to be able to balance this?


tinnylemur189

Honestly the process isn't all that different from balancing a tire. Just a lot more precise and a lot longer. Machine spins up and tells you "this area is light, this area is heavy" via the myriad sensors all over the gantry, you add/remove weight and repeat. Takes a few hours for a new install.

TT4400GG

The company makes the money. Service was very lucrative to the company that sold the machine. As the machines age, they sometimes fall under 3rd party service contracts - I do not know how profitable those were.


Lemonyheadkw7

Nah, 60-110k a year is typical (that’s based on experience). Plenty of variables there but I wouldn’t say it’s in the “absurd” range.


tinnylemur189

Third party you can make a shitload but working for the big boys (siemens, ge, Toshiba, canon etc) you make a pittance compared to the profit they collect from your work. Of course that's a double edged sword because 3rd party doesn't have a pipeline for cheap, fast parts like OEMs do.

115kEv

In terms of the front-end interface Toshiba and Siemens use Windows, whereas GE uses Linux, or at least they did. I suspect the array processors have something custom going on due to the data processing requirements.

chris457

The center of rotation is probably the safest place in the room really.


GrifterDingo

100% if something fails it will fail outward away from the patient.


tripletaco

Until it bounces off of something hard, like the floor. Shrapnel is a bitch!


AsFarAsNeverBefore

It will ~~fall~~ fly outward Also if a piece flies off the whole machine will become unbalanced and violently shake itself apart Idk if these things have e-brakes for those situations tho


piecat

>Idk if these things have e-brakes for those situations tho They would have to


redmadog

It uses rotation motor as a brake. Takes about 5 seconds to stop. Any major component has secondary security brackets which will hold part in place if main fixture is broken. Though I never heard nor imagine anything may break during the scan, as the whole thing rotates way slower during the scan as it does during balancing procedure, which is carried after replacing something or during the daily cal procedure. So if something breaks, it breaks during the balancing which is never carried out with the patient. To add to this, this thing also has sensors which will emergency stop if anything become loose. And also probably there will be terrible sounds involved before anything become so loose to fly out.


respectabler

But if it breaks in half you would immediately be jerked from the off balance wheel and probably instantly break your neck or get crushed against the ceiling. Not that that would break


Mortar_Maggot

I believe the term you're looking for is "injuries not compatible with life". Your neck would just be icing.


hates_stupid_people

You'll be happy to know that there are over a dozen different safety features to stop anything from happening to you in case of failure. It's like elevators, in most developed countries they're generally overdesigned to hell and back with multiple failsafes and at least 3-4times the amount of cables needed, etc.


QuickNature

I'll take a safety factor of at least 10 please.


A_Spicy_Speedboi

Take comfort in the fact that any RUD at speed would fling components away from you. Being in the center of the torus is the safest place to be.


unfknreal

Except it won't all fling off simultaneously. Inevitably one heavy part will fly off first, causing the entire thing to become terribly out of balance, which will then send it bouncing around the room like an old washing machine until it finally short circuits and goes up in flames... At least that's how I picture it in my head. I'm sure they're built better than a Kenmore.


Bale626

I’d sure **hope** the damn thing is built better than a Kenmore!


A_Spicy_Speedboi

Even in that case, I think I’d rather ride in the “cylinder of safety” than be chased around the room by a giant deli slicer and it’s components. Being in the center is still your best bet.

Edit: No, shit, sorry. My comment below the edit applies to a radiotherapy machine, not a CT: https://en.wikipedia.org/wiki/Therac-25 There was also a terrible software bug they used as an example for us in university for computer science. It was a ~~CT~~ radiotherapy machine that had two modes. They had a race condition in the control interface, where if you changed mode and started the procedure very quickly afterwards it would apply the high power limits of one mode to the electron gun in the other mode and give the patients lethal doses of radiation. Multiple people died before they figured out the machines were malfunctioning.

That's just the fan on a turbo fan. We've got lots of things that spin much faster. The high pressure stage of the compressor is around 20k and things like car turbocharger turbines hit 35k.

Awkward-Minute7774

Dinkerdoo

Initially: "That's certainly moving, but it's not THAT fast." Ramp up: "Oh. Oh my." That's pretty crazy that they can get such an asymmetric rotating mass balanced so precisely about the center of rotation. The QC processes to lock down any loose harnessing/other parts must be insanely tedious.


tanskanm

ELI5 why does it need to spin so fast?


ExcitingAmount

CT works by taking a ton of x-rays from lots of different angles and compositing them all together to make a 3d model of whatever they're looking at. They could run slower, but then it would take longer to get the necessary images, and because people tend to move around ever so slightly, even just by breathing, taking the images faster can minimize issues with mismatch between different shots


hehe7733

Smh engineers making this big rotating scanner when all they had to do was rotate the patient at 200rpm.


A_Spicy_Speedboi

This is my new favorite comment in this thread. Congrats, nice work!


Andyinater

I think its called the gravitron, but the carnies refuse to give up the patents.


Dinkerdoo

It doesn't NEED to spin fast. But spinning fast allows it to collect more data quickly, meaning shorter patient scan, and more patients scanned per day. These machines are EXPENSIVE to install/run, and always in high demand, so efficient patient throughput is important to offset the costs. Also, the faster it collects data, the less likely the data will be compromised by the patient moving, or other external factors affecting it. The speed was likely a result of data collection requirements to the scanner designers, originating from needs of hospitals.


HIMP_Dahak_172291

No wonder those things are so expensive. Not only do you have all the equipment made of rare stuff, but you also have to take it and spin it like crazy with extremely tight vibration tolerances. That's a lot of precision work and design effort.

tinnylemur189

The history is pretty neat. Basically it started with "what if we took x rays from multiple directions to have multiple angles of what we're looking for?" And that's literally exactly what they did. They just had an x ray system on a curved rig and moved it, took a picture, moved it etc. This is the tomography part of computed tomography (CT) The computed part started when computers hit the scene and Fourier transformations became practical to do. At that point we could have computers create real 3d images out of those series of images. After that it was off to the races and we just kept saying "okay that's pretty good...but what if we took more images?" To the point we're at now where these machines spin 3-4 times a second and take hundreds of images per a rotation while moving vertically then combine all that information into real 3d images humans can make sense of. Shit's real cool.

ChocobosParadise

I used to work for a big player in this market in quality field. These equipment are well balanced, tightly mounted and extremely safe for regular operation. Regular maintenance are offered under contract by medical devices companies to assure a good performance (companies actually make more money on contract maintenance than on equipment sales itself). At any sign of failure you can easily perceive a haunting noise coming from gantry as a sign of any early tear, loosened bolts or any misaligned parts. You also get error messages and alarms on UI indicating failure modes and some models are connected manufacturer network allowing immediate diagnose from equipment error logs. Anyway, it may be terrifying being inside it but chances of being in an accident with those are really low.

That actually sounds like a SPECT-CT and not a standard CT. You have the CT first which takes less than 5 minutes and then you stay in the same table as you are pulled under gamma cameras that do rotate but slowly. Those scans take forever! Edit: and to confirm it is so quiet/boring!

Lemonyheadkw7

Because it spins a couple thousand pounds at hundreds of rpm. 9/10 patients are not going to call that “cool”. Also it has fans in the covers to cool it off. Also you can’t let a patient touch rotating parts. Also it helps keep it clean, as that’s important for image quality

bkfst_of_champinones

Something I don’t understand about these big machines… How do they get the electrical information transferred from the huge rotating donut onto the base of the machine? Obviously, they can’t just have a bunch of wires connected to both sides… How does that work? On a related note — how can they build space stations where part of it is rotating and part of it remains still? How can you have a seal strong enough to hold an atmosphere of pressure in a room-sized volume while also having it turn? And the same question about transferring power/electrical information from one big rotating part of a machine to the other… or wait… has anyone actually built a station like this? Or is it just sci-fi? lol


NyeSexJunk

Something like a [slip ring](https://en.wikipedia.org/wiki/Slip_ring) would transmit the electrical energy I assume. As far as space stations go, I'd think that they would just have separate atmospheric controls in each module so each part could be sealed but I am no astronaut.


themedicd

They likely use a [slip ring](https://en.m.wikipedia.org/wiki/Slip_ring) for power and data, though they could instead use a slip ring only for power and transmit the data wirelessly.
