Years ago I had a serious problem with GERD (acid reflux/heart burn) that I eventually had fixed via surgery. Prior to surgery they try various medications or behavior modifications to control the disease as an alternative to surgery and this involved several visits to a radiologist. At one appointment he said "you seem like the type that would be into science..." and after I confirmed his suspicioun he offered to show me a "live x-ray" of my digestive track while swallowing to help me better understand the mechanisms involved, but at the cost of a slightly increased x-ray exposure. He felt it was safe and worth the effort but didn't want so it without my understanding and consent. I was, of course, excited and approved and he brought up a live x-ray of my stomach and showed me exactly how swallowing worked while my body was resting in various different positions. It's actually a lot faster than you think it works be, the food launches down your throat like it was shot out of a slingshot. The "plumbing" of your upper digestive track is actually fairly simple and changes in how you lay in bed can have quite a dramatic affect of the ability of the contents of your stomach to migrate back up your throat. It was very informative and well worth the slightly increased x-ray dose in my opinion.

Cracking the joint though...that's an interesting phenomenon. It's a rapid dissolved gas release from the synovial fluid. The bones move quite fast.

In 1972, Field Emission Corporation had a high power pulsed x-ray machine that ran at 1000 frames per second. The setup used a Varian image intensifier tube and a high speed camera with rotating mirrors so the film never slowed. The demonstration showed a model airplane engine running. The actual use was to image pig brains under high G loads using a rocket sled and rapid deceleration. The data was used by the space program and military. Other products allowed stop-action x-ray images. One machine was capable of producing a 2.5 MeV pulse of 4 ns duration. There were interlocks to the room because the scattered radiation dose from one pulse was lethal. The unit was used to x-ray bomb detonations in the dessert, x-ray aircraft engines, simulate atomic blasts in small spaces, radiation harden semiconductors, and other things.

We are using DECTRIS detectors at work (synchrotron beamlines) so I was very intrigued to see one of these on your channel. Amazing video. Another thing worth mentioning is the extremely high dynamic range on single pixel level, unlike any other X-ray image sensor. With these detectors any individual pixel can collect around a million photons before it saturates while the adjacent pixels still remain sensitive to single photons, so there is no bleed over as in CCDs. At the same time you can resolve intensity variations of a million to one while CMOS sensors typically saturate at 65000 counts. That's why they are so valuable for synchrotron science where the X-ray beam is tens of thousands times brighter than from an X-ray tube. By the way, the reasony why they're not so common in imaging is because their pixels are relatively large. The Pilatus models comes at 172µm and the new Eiger models have 75µm pixel size. That's a lot bigger than 5-10µm in high resolution imaging systems (with a much worse signal-to-noise-ratio of course). And of course, they are way more expensive than traditional imaging sensors...

Aren’t modern CCDs pretty much immune to bleed as well? I thought all of the bleed you see in visible light photography is caused by diffraction and other artifacts from the lenses and aperture. This setup doesn’t have a lens and no real aperture, so no bleed. I might be wrong though :)

Yeah, TIFF is more a container for images and metadata and than a format. Not many people realize that even that container can have two byte orders and either 32 or 64 bit offsets. Then add ability to contain multiple images at different resolutions, possibly independently compressed stripes or tiles, compression can be LZW, Deflate, (less common is JPEG or basically anything) like 20 commonly found metadata records (tags) describing width, height, number of bytes per pixel, number of channels, meaning of channels, ....) and then some less common, but important for some applications. Not to mention that some programs are using these metadata creatively, so you can find SEM image with 254000dpi (example - 10000px/mm or 10px/um or 100nm/px - not even high resolution 2000px wide image shows 0,2mm). And fun starts when you try to use TIFF for storing extremely large images in tiles - any program that opens it may try to read all data, display that image and either crashes or consumes a lot of memory. Fileformat itself allows it, problem is that most programs ... ehm ... none .... could handle some extreme use cases.

👍Always love how you describe some of the mundane tech challenges, 32b tiff, image processing, etc.

They had these verticle machines where you place your feet, with shoes on, into a compartment at the bottom and you looked into a viewer at the top. You could see your toes and bones and could tell if the shoes were of proper fit. Of course, it really didn't matter if they fit or not because you died a few days later.....not really, but they were apparently dangerous as they did not stay around long.

That's exactly what I was thinking of during the video 😂 I think they were fluoroscopes? I can't remember and probably wasn't told correctly in the first place.

From what I understand is you as the customer did not get a huge dose from your limited time with it BUT the salespeople... They got the literal brunt of it.

@@MakeItWithCalvin So, this is correct, the salespeople did get the major doses of x-rays from the machines, but they did stick around for a decent length of time. They are known as Shoe-fitting Fluoroscopes, and they were invented in the late 1910s, and in the 1990s new regulations were recommended by the ICRP. Which implies that, at least in some places, they are still in use as of the 1990s.

@@rambysophistry1220 Those machines are likely a large part of why the dental xray technician physically leaves the room as you're getting your xray. Ideally those rooms are lead-lined as well, and not just drywall...

1:16 what fascinated me most about this video is this clip where we see your bones inside your finger while flicking the switch! 😮

I paused as you went along and did the steps myself and that helped a TON.

I always look forward to these!

A collaboration with the "Ant Lab" channel in this vein might be interesting. He does a lot of high speed optical footage of various interesting insect behaviors (jumping, flying, etc.), for research purposes, and I imagine he might have some thoughts about a good use of something like this for research.

Thank you for explaining the jumping beans!

Of course we found it interesting! I had wrist surgery years ago and had the three bones closest to my arm removed. I would so love to see what the heck that looks like in the x-ray!

Great stuff Ben - you are never short of fascinating surprises :)

I don't know why but I love X-Ray equipment.

I wonder if you could catch video of an arc between those switch contacts, what it would would look like?

Glad yt started bringing your vids to my homepage

Mr. Science, you're one luckiest guy in world of electronics and physics and you grow your hungry every month and suprised all of us. You are serious innovator of future Mr. Science juniors! You have make effect that never goes away, no matter if you stop everything today, BUT, PLEASE DON'T DO THAT!! Keep going and create ideas that anyone cannot even imagine. It isn't problem for you, and you enjoy everything all this. And get own counter that is in your pocket full day, and write down every day how much you get that dark power.. (: Thanks man! You're God of technics.

Literally the coolest thing I've ever seen on this channel!

Woah! I mean stationary x-rays are pretty cool, but moving x-ray images? So epic.

Wow I had no idea these "Mexican jumping beans" were a thing!! Mind is legitimately blown!

That’s insane! Keep up the great work!

I was just wondering when a new one would come out, thank you for this

Man, I'm always searching for this very thing... thanks!

As an engineer specialized in human interfaces, this camera have a huge value. Be able to watch the biomechanics of the bones and tissue paired with the mechanics of a switch, push button, know... open the door to a whole new level.

Ear-buds playing bass-heavy music? Love the real Mexican jumping beans - the ones I got in England were just a ball-bearing!

It's always great to see you post!

Dectris MVP! love that they are letting you use this!

I think many of us just stopped whatever they were doing as soon as they got the notification!
