MRI Upgrade Timelapse - Two Weeks in 4 minutes

A factoid-filled timelapse of upgrading a Trio whole body MRI scanner to a new MAGNETON Prisma 3 Tesla system. The installation took place at the Biomedical Imaging Center at the Beckman Institute over the course of twelve days. Here it is in 4 minutes.

[@KallePihlajasaari]

@@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.

Nothing is more daunting than day one of the upgrade . Or more rewarding than the last day and startup and Calibration.

[@Finezzato]

that's insane tech that we take for granted

[@christopherleubner6633]

The "bore" is a big ole electromagnet called the phase gradiant coil. It compensates for irregularities in the static field of the superconducting elecromagnet and emits the RF pulses that make the images on the sense coil. Also they ramped down the field coil and recharged it. The gas cylinders were nitrogen and helium. The LN2 is added first then the helium. They pretty much stripped it to the cold head and the magnet and completely rebuilt it. 😁🤓❤

[@flintthuang]

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.

[@jazcatFL]

@@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.

[@vladimirkuznetsov6233]

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.

[@timprice516]

The cylinder you lay in isn’t called the bore, this refers to the opening of the magnet. In the bore of the magnet are the gradient coil And the body coil which is the bit the patient would lay in. The bore of this 3t magnet is 90cm the size of the body coil 60cm.

Do you recover the Helium before working on an MRI like this? Surely there is a way to recover the Helium for upgrades, I can understand venting in emergencies but you'd think it would be possible to recover it under normal circumstances.

[@justintyme2764]

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.

[@Unknown_Ooh]

I've always wondered why the MRI room is always cold and now I know lol

[@avestator3763]

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;)

For this major upgrade I assume the magnetic field was reduced, hopefully while preserving much of the helium. I am curious however about minor repairs that might involve metallic parts and tools, that would be a challenge.

[@kadirzhanl]

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.

[@TheTerrorJumper]

@@kadirzhanl the magnetic field is always on

[@cbrown596]

@@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.

[@AXNPictures]

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

[@cbrown596]

@@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)
