3:25 Button box seems overly complex and expensive. Just run 5 fibers to it and connect the 5th fiber to the 1/2/3/4 variety of color fibers when the buttons are pressed. Or even simpler, run 8 fibers and have the switches literally just cut the light path as they are pressed. The steering wheel can be like an optical encoder. A grated wheel that spins as the wheel is turned. With four fibers (TX1/RX1/TX2/RX2), you can determine direction. (Like the scroll wheel in an old mouse. In fact, you can probably literally use the chip in an old mouse.)

Hope you’ve had luck with your cancer treatments, surgeries, medications. I’ve had at least 25 MRIs in 2022, now I’m spaced out to every 4 months for now. I’ve had 6 tumors in my brain, not all at the same time 1999(1), 2002(1), 2022(5) and 7 surgeries. I was super lucky to go 20 years without any issues or medications. Then out of the blue I had a seizure and that’s how we found them again. They’re grade 3 tumors same exact as I had 20 years ago 1p-19q co deletion with mgmt promoters. Same as before, I did photon radiation the first time I had it. I am taking the same chemotherapy as last time procarbazine (matulane) and a couple hours on the iv at the hospital on day 8 and 22 of my treatment. The rest of the time it’s just pills. I still have spots on the brain that light up with the dye. My neurosurgeon takes the time to go over previous MRIs vs current MRIs.

I got diagnosed with melanoma in 2004 and metastasis in 2006. Oncologist at the time gave me 20% of surviving 5 years. I'm still here, fighting. I'm on immunotherapy for the cancer. Found one metastatic brain tumor back in March (2022) on a random MRI (lousy birthday present, by the way, but they wouldn't let me return it). Tumor was killed with a Gamma Knife procedure. About a half day of additional CT & MRI, fitting for a mask to immobilize my head, and such. The actual procedure only took about 7 minutes in the machine. Now I get brain MRI and head-to-toe PET+CT scans every 3 months. Besides my oncology team, I have a friend who is a radiologist at the hospital I go to. I ask him to look over my scans; he's VERY thorough.

This was so cool! I worked at a major research institute attached to a hospital. The MRI was in a temporary building with TILE FLOORING. Well, one night the janitor, who I had a nodding relationship with, was tasked with cleaning the MRI area. The floor was scratched up. He decided to do a really good job and buff it. He went one inch over the yellow stripe on the floor, and the huge buffer machine was ripped from his hands and went into the machine. He was so frightened, he just went home. He didn't tell anybody, certain that he would immediately lose his job and probably have to pay for the damage. The next day, his boss phoned him and said please come back, nobody is mad. He kept his job, and they hospital put in an order for a new MRI machine. He was a very nice gentleman.

Another fun-fact: The RF-coil produces the stimulating RF-field. The gradient coil does not produce the RF-field. The gradient-coil produces - you guessed it - the *gradient* . This is similar to tensioning several identical guitar strings at various tensions so that each one 'plings' at a slightly higher and unique eigenfrequency.

@MrDaExo Год назад

@@marklemont3735 unfortunately MRI is Indeed very loud. There is not much more you can do as a patient than ear plugs and the headset. However, from a technical side, the noise highly depends on the type of image you are scanning. That means that the difference is not necessary the biggest between field strength but rather what kind of tissue you want to highlight in the image. There are ways to make the scanner quieter but often that requires longer exam times or may result in worse image quality, therefore it's rarely used in clinical routine except for pediatric patients.

@SeanBZA Год назад

Not many manufacturers od MRI machines, so really the only difference between them is age, and the newer ones tend to have better response, and are slightly faster, and of course a larger aperture for the patient. Making it bigger is the largest cost, it is not a linear increase in price and complexity, but exponential. $2 million is the price of a used one, less the actual cost of installing it in the nice new concrete structure you have to build for it, which also has specifications on the types of concrete gravel ( all non ferrous) along with the types of reinforcing you can use, and the layout. Then the copper shield needed to make the Faraday cage around the room, and then the doors and windows to access and see in, which need to be continuously bonded and also have shielding inside. Installing one can easily make the purchase price the cheapest part, then you need all the support equipment, and the backup generator sets to keep it running in a power cut, along with fuel for a month of generator running.

Couple of comments : At 4:51 : The "arms" around the Head coil do not contain Gradient coils, nor do they "put out" any Radio frequency. The arms actually house RF loop elements that actually pick up signal from the brain. The head coil that you have in your hand is a receive only coil and does not transmit any RF......the RF excitation pulses are transmitted by the Body Coil inside the scanner and the Head coil only "picks" up the signal from the brain, amplifies it using preamps and feeds it into the scanner for further processing via the connector you showed at 5:00

@TannerJ55 Год назад

Thanks for the clarification! We do have a TR coil that can also be used with our machine- would that coil use the included transmitting coil and the body coil as well, or is the body coil only active when the head coil is only receiving RF?

@georgeverghese1009 Год назад

@@TannerJ55 In a TR coil which is used mainly due to SAR considerations, the local TR coil transmits and receives during the whole exam.....,...the body coil is completely inactive when a TR coil is used and is in a "detuned" state.

Some MRI scanners have pneumatic headsets. The speaker is mounted in a fixed position within the scanner. When the machine is set up, the technicians use phantoms and a calibration tool to measure the shape of the field and trim it to size by placing metal sheets of varying thickness in rails running along the bore. The calibration tool software will suggest a size and slot position. Another interesting thing about the installation is the room - it’s a faraday cage. The doors have metal seals consisting of copper fingers or a tape with mesh to prevent RF leaking into the cage. Also, cables and oxygen tubes are passed through a tube in the cage rather than a simple hole; the hole would cause RF leakage. Instead, a tube approx 200-400mm long is used and welded to the cage. You can see the tubes (bottom right hand side) and copper sheeting of the cage at 15:55. It is longer than the RF wavelengs and prevents leakage. The windows also have mesh to prevent leakage. The AC supply to the lights and plugs also go through signal filters when they enter the cage.

I had to get an MRI and ended up 3D printing mine, I even made a simple tutorial on my channel you can reference if you're interested (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pcjv1BP5xDQ.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k1WIpwV-8lE.html). Glad you're feeling better and I look forward to seeing more from you!

I just remember that you needed to take time off for your concussion. SO good to see that your well enough to be making videos again! My wife had a concussion last year and it was no joke. She was out of commision for 3+ months.

I was recently in an MRI for a shoulder scan and I had some insanely epic hallucinations during the tests it was crazy. At one point it was almost like I could see the warping of the space around me.

This happened to me during a CT scan. When I walked in the room, I saw red laser beams everywhere. Beams that no one else saw. I smelled a weird chlorine smell. Once in the scan, I saw like a thingy flash and light, similar to men in black. I jumped off the table. They tried to convince me that it wasn't real. They tried to make me do it again. Same thing happened. I jumped off the table. I recently tried to do a MRI and I now have PTSD from that CT situation and the shadows when eyes are closed and the loud noises were too much for me.

Unfortunately having done quite a few MRIs, this was a really good overview. One thing I'm still curious is, what's that beating/breathing constant sound inside de MRI room?

@JackieBright Год назад

I have no experience with MRI machines, but I'm pretty sure that's the sound of the liquid helium cooling system

@KonradTheWizzard Год назад

Beating sound: The magnetic field of the machine is quite strong and at least part of it flips all the time. This extreme change of forces in the magnets causes the material to change shape and bang against its housing. If you use a power supply close to its maximum power you will hear a faint buzzing noise - same effect, only in the MRI it is much much stronger. If you hear a breathing or whirring sound it is probably part of the cooling system. Might be the helium system for the magnets or the air conditioning for other components or for the room itself.

@davewhomri Год назад

That sound is from something called a “cold head”. It re condenses helium gas back to liquid inside the magnet. As an MRI tech for 26 years now, most times I don’t even notice that sound anymore (until it stops)

7:31 had an MRi of my head 2.5 weeks ago for damage around my “hearing loss” I’ve been experiencing caused by tinnitus that started back in February and just has gotten worse. Also found out that I have a hard time hearing in the 4,000Hz range more so in right ear than left (but it’s in both ears), & b/c of the tinnitus and small amount of hearing loss; will be picking out, fitted, & getting hearing aids for myself by end of the year (will be a custom made set and will also include Bluetooth, which I think is really cool as will be able to use not just for hearing, but connect to things like: family TV that luckily has Bluetooth and will be able to turn up/down volume so I can hear w/o turning up/down for rest of family….I think that’s awesome. Should also be able to connect to my smartphone, again….awesome….etc) and hope they end up turn out, & work the way I’m hoping they will; along w/ not getting “ear fatigue” from wearing headsets/earbuds while gaming, working, etc…..but will have to see. Also glad have insurance (which only pays 10%-20% of cost, but better than nothing). So I had this headgear on in the MRi and Doc wanted contrast, but had allergic reaction last MRi and so tech said nope, not doing contrast. Which brings me to my 2nd story real quick like. When had a scan back in 2018 it was from chin down and pubic area up that they scanning. Well, I’ve had CT scans before, MRI’s before and so on so thought nothing of it. However this test, I had to squeeze the bulb for them to stop the test because what was happening to me is: I was baking from inside out! It was also exacerbated from the medication I take and for them to get the scan completed: I was in my underwear, no blankets, had 5 fans on me as were trying to cool me down. That room already kept at pretty decent temp as is, but what a feeling to have and buckets of sweat pouring off you, lol. So much fun, so I get when he says “will start to get warm’, and it’s not a pleasant experience at all.

First of all great to see you back Scotty! Second, as someone who will be starting school to be a Diagnostic Radiologist, I found this video very informative and amazing. I've never seen a video showing how a MRI machine truly works, including a brief look at the software behind it. Great video, and again, amazing to have you back!

@GuyWhoReviewsStuff Год назад
