MRI Upgrade Timelapse - Two Weeks in 4 minutes 

Cause it is interchangable with the New one so they dont bother to use a New Core system

The core part is mostly the magnet, it should be just as effective as a new one. Plus they’d have a hell of a time removing that iron core it would weigh tons!

More upgradeable than an Apple Macbook

llary and probably cost less to upgrade too

@@Ian-pe9rj The magnet is mostly superconducting wire in a massive vacuum insulating dewar (thermos) and is a decent part of the cost. The more prosaic reason for upgrade may often be that it is too expensive to extract the magnet from the facility that may have had renovations around it that prevent it leaving the building without cutting holes in walls. It is impressive that they full support upgrades though.

I know right? It's terrifying. Claustrophobic as hell.

Never knew the coil was a piece that could be removed...

@@leemilica Bore, not coil. The coils are outside the core unit and have NOT been upgraded here. The coils are being re-used as they have the windings to provide the same 3T field as the upgraded unit.

fascinating to see but not to feel...

@@leemilica The coils are superconducting during operation, so no upgradation is required. However the core needs to be upgraded to prevent from saturation.

no

:DDD

Same man🤣😂

And I just had a nerdgasm! 😂

Very impressive. We only see a plastic machine that makes a whirl sound. It scares me a bit, to know that there's a gigantic magnet wheel spinning very very fast around my head haha. Big respect to you and the other engineers.

Now the upgrade is done with a team of 2. And ramped and calibrated by one

Sounds awesome!

Modulate the frequency and transmit

Please I want to know more about the MRI electronic. Could you please recommend me some books ? Regards Here is my email. b.guifo.athanase@gmail.com

I would never have expected to find the designer in the comments section here. That’s awesome!

more wires!

Let the bolt go.... nothing will happen.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5z33ZcDgavY.htmlm49s

PC GUY 1241 lol nice one... but I think the helium release bolt is a bit too big to miss...

Yes... Is it a bolt by the way? not a valve?

What bolt, I have noooo idea what you're talking about

if you didn't need the bolt, than you actually upgraded the design of the machine. xD

I heard of a MRI install where the hospital maintenance engineer saw the waveguides (through which cables leave the scanner room) sticking out of the Faraday Cage and, without asking anyone, took a saw to them...

stainless steel laughs at magnets.

FCOs....I can guess who you work for!🤣

They watch the tunnel's too.

What is the CAVE?

@@litarea I can't find what the acronym stood for, but it was a virtual reality system originally developed at UIC in 1991, and one also existed at the Beckman Institute at UIUC from 1995-2017. It was a smallish cube-shaped room that could hold maybe 10 people or so if they huddled close together. There were projectors on the walls and the floor, driven by a bank of SGI workstations. In the '90s, it was a mind-blowing experience, but these days it's probably been made obsolete by virtual reality headsets.

True. I once did a major upgrade and repair on a CT scanner on a tight timescale. The customer told me that when it worked it was the first time they had seen me smile! They quickly found the upgraded scanner somewhat disrupted their work routine... 'Volume' scans, where the unit scans a large area of the body in one go, used to take about 15 minutes to reconstruct; I was there when they did their first post-upgrade scan, the scan completed and they went to put the kettle on, before they reached the kettle the images were ready!

You can buy a cheap one for just a million on a Chinses amazon according to my professor technology who give courses about technology in medical imaging

Maybe look on aliexpress. Free delivery 😜

i know a cool website where you can buy used mri’s for under 250k bucks have fun with scanning yourself but you need someone who presses the start button www.dotmed.com

That would be a MRI selfie, right?

Well, you'll still need someone to tell you what is in these images :-D

There are regular quality assurance testing that being done weekly and monthly with several certainly shaped bottles filled with physio fluid called "phantoms". But after a major change like this there should be done way more extensive testing including the checking and shimming the main field itself as the new coils can couse a "disturbance in the Force" slightly differently than the old ones;)

Is it very expensive to ramp up the super conductive coil? I heard that there is very high chance the ramp up process will fail.

@@flintthuang a quench, sudden loss of the magnet field, very rarely happens anymore during ramping, the process is mostly automated nowadays. The increased cost is from the increased Helium usage during the ramp. Ramping causes the temperatures inside the magnet to increase which increases burnoff of the Helium.

Two Dewar flasks are indistinguishable, I think both are helium tanks. I think, they just kept the magnet in cold state, but refilled an inner liquid helium reservoir. If you do precooling with nitrogen, you need to evacuate leftover nitrogen completely to prevent condensation.

Whew, I was a linac specialist for 10 years...bless you🤪

Here ya go... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1ZY4F-DUXC4.html

The magnet is ramped down removing the magnetic field thus greatly reducing the helium boil off during the upgrade and eliminating the dangers of high magnetic field. While the magnetic field is down there is still a substantial amount of liquid helium within the magnet that continues to be preserved by the cold head recovery/boil off reduction system.

They're custom made for each system

this isnt a washing machine

@@ragadoodle But if it was, I bet it wouldn't have a "ferrous metals" cycle, right next to the delicates cycle. Maybe a "Create high resolution, cross sectional images of soft tissue using magnetic fields" cycle though. That would be right next to the water level setting.

The LHC is probably the most complex device ever constructed by man. Think of the requirements of building an acceleration circle a mile or more in diameter that is precise enough to line up two (or more) subatomic particles for a collision from opposite directions and then measure the directions and velocities of the newly created particles.

@@JustWasted3HoursHere you're correct! It's the most complex structure built by man. I've seen a superconducting cyclotron, it's very complex. Can't imagine how complex the LHC is.

@@Chopper153 It is quite an achievement, no doubt. And there have been very recent physics-shattering (potentially) developments with particle physics: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-O4Ko7NW2yQo.html

I ended up here because of my GP

And post op, in a CT scanner

@@des_smith7658 Hope you're healing, wishing you all the best.

@@danatmonst3594 thank you for the kind wishes I have made progress and have normal psa now

@@des_smith7658 Wow! Thats awesome news!

Thank you, I was wondering if anyone else caught that.

The magnet is mostly superconducting wire in a massive vacuum insulating dewar (thermos) and is a decent part of the cost.

The coils are being kept as they're superconducting.

Бро! Ай фил ё пейн!:)

Their home?

Same with CT machines. I never realized it was a rotating vortex to another dimension.

@@GeneralChangFromDanang 😂😂

Sergej Nadaždin it is me, but in the future... also a correction: thought not taught.

The magnet is inside the chamber, the gradient coil is used to shift the magnetic field direction rapidly to obtain "contrast" so the scanner can see the images of inner tissues

Complex indeed. When this technology first debuted in the mid eighties it was the third most complicated system designed by man. The space shuttle was number one and a nuclear submarine number two.

Not rocket science then?

Considering turbine engines are dead simple...

Unfortunately not, but I wish it was.

The world is run by bureaucrats. The engineers just design all the stuff.

And probably found all the missing 10mm sockets during the first test run.

A Tesla also happens to be a unit for measuring the power of magnetic fields.

@@brendog217 thats not what the original comenter had to say. Theres a typo in the video and it says t e L s a

As far as I know, MRI uses electromagnets which means they only magnetised when electricity flows in coils. So when the machine is not operating, there is no magnetic field and repairs with metal tools and parts should not be an issue.

@@kadirzhanl the magnetic field is always on

@@TheTerrorJumper incorrect, modern MRIs are not permanent magnets, they are electromagnets. Siemens connects a RAMP down kit to the positive and negative connections and are able to pull the amperage out of the system. Room is perfectly safe to work in while this upgrade is being done. The Ramp down also does not typically affect the helium level as the helium compressor is kept running. What this video left out was the upgrade performed in the equipment room where power cabinets are replaced. This requires 480v power to be cut to the equipment, so you lose recompression of the helium until you are far enough along to reconnect power.

@@cbrown596 In the end it looks like they filled up with helium so wouldn't that mean that the old one was quenched?

@@AXNPictures No, during the upgrade procedure power is shut down to the cold head as you are replacing everything. The MRIs pressure bypass valves are set to vent excess pressure in a 'transport' configuration. Since the helium is no longer being recompressed by the equipment it starts to shift from a liquid to a gas and expand. If you didn't allow it to vent, the pressure would build up enough that it would rupture the overpressure burst disk and cause a quench. So over the course of the upgrade you lose helium at a rate of about 3% a day, so they will typically top it off before, and after the upgrade. If you allow too much of the helium to vent (helium level gets too low) it causes the internal temperatures to raise too much and can make it difficult to refill as the helium will now flash on contact with the 'warm' MRI. They then need to use almost 3 times as much liquid nitrogen to cool the internals, to then add helium, and then siphon nitrogen out in phases. (Huge pain in the ass)

Biomedical equipment tech, community college/tech training or Military Biomedical Repair Tech for starters. Problem solving mindset, how ever long it takes, pay is not a direct reflection of skill unless you own the business model along with sales. Starting out can be as low as 20k usd-and up.

@@LifeBloodMarketing my first year (2007)with no training i made 60k because of the demand…. Im actually in this video training two technicians 😒
