We can X-Ray Gadgets we Review Now! - Lumafield CT Scanner

Casetify gonna take screenshots of the video to use in their new skins and cases.

fun fact: your main concern when putting electronics in there should not be the bit flips (you can easily reflash a bios or so) but with enough radiation you drastically lower the gate threshold voltage of the mosfets in the IC which may start to leak and misbehave. Which would also invalidate your performance/ temperature and lifetime testing. This is highly dependent on the node size and type of the IC. i wonder how many kRad they pick up during the 12h Test.

One of my best friends from high school (Kevin Cedrone) is the Co-Founder and Lead Researcher at Lumafield. He is/was a brilliant guy who used his intellectual gifts to achieve some amazing things. Not bad for a guy from Malton, Ontario who went to one of the worst high schools in the region (Turner Fenton - we were all trucked there for the gifted program). Haven't talked to him in ages, but I'm very proud of him.

As an orthopedic surgeon I use CT imaging basically daily. I can understand your almost child-like amazement. The first time I saw terrarecon about 20 years ago do on the fly reconstruction of CT imaging I was similarly amazed. Now I use intra-operative fluoro CT (medtronic O-arm, and Globus E3D) almost every day for 3D imaging to robotically assist screw placement for spine surgery. Fun fact: CT scanners used to take forever to get an image series done because the amount of processing power to reconstruct the images was too much for the computers of the time. With increasing slice counts on the scanners, and faster processing it now takes mere seconds to scan an entire person. An MRI, by contrast, works by inducing spin in the protons in the water of the material, and the image is taken after a certain specified amount of time after the spin is induced. That time you wait to take the image is a property of which type of MRI sequence you are trying to obtain. That time you need to wait is a property of the physics whereby the image is produced and cannot be sped up.

As someone that works in Industrial X-Ray CT - it NEVER gets old!! P.S. the carbon fibre is just a protector for the actual detector - it’s much cheaper to replace a scratched carbon fibre plate than it is the detector!

I wouldn't be surprised if this video actually moves several units for Lumafield. I'm sure there are companies out there who would love to do a 1-year trial run with this thing.

You should scan a Video 8 / Hi8 home video camera/camcorder. They have HUNDREDS of mechanical parts packed into a tiny form factor since they are essentially tiny VCR's. The engineering behind these tiny devices with so many tiny intricate moving parts has always blown my mind, would LOVE to see one scanned!

I've visited Lumafield's office in San Francisco, great team to meet and ask questions. Their solution is very innovative for what it does, especially when it doesn't need an industrial X-Ray tech on staff. I'm told they do work with aerospace and defense contractors, so I might actually meet an aerospace engineer ("Rocket scientist") there next time. I could see this used for QA checks of completed assemblies, where an incorrectly assembled part in say a Fuel Control Unit in the engine of an F-16 could cause a $30m jet to crash, and has at least once. One disappointment when I visited their office, I only met a neurosurgeon there, and no rocket scientists there.

As a CT Radiologic Technologist, I am happy by how much Linus was fascinated about a technology I use every day.

One of my clients had a CT scanner significantly larger than this. I urged them to started making social media content with it to help build brand awarenessand pivot from production to testing... They have since downsized to a fraction of their old company size and will likely be closing soon. Engineers are numb to how cool their own tech is, CTs are sick af!

I worked in an electronics failure analysis lab in college and we had a manual version of this machine, and it was already a bit old when I started working there. We would mount an object on either a plate or in a gripper and then manipulate it with joysticks in three dimensions over an x-ray projector. We could snap pictures of solder joints, BGA chips, and such for clients. It was great non destructive testing and it's really cool seeing the automated version of this in action now.

Australian here 👋 we use these in our Airports.. I was a an operator in an international airport for a while. Amazing to see how advanced ours are. What took this scanner hours takes our machines seconds.. granted ours costs an undisclosed amount of millions of dollars lol. Was a really cool job and got to see some funky things

The thumbnail and nondescript title had me thinking this video was gonna be about some horrific and unethical AR headset that uses ionizing radiation on whatever or whoever you point it at so you can see through the world around you like a CT scan

It’s so cool to see the radiation fly through the sensor of the interior camera 8:30 (the little white specks you see flashing)

Babe, wake up, it’s April and Linus is doing tax rebate purchases

This is one of the best LTT videos ever. So far beyond what any other tech show is doing, not just something you can order on Amazon but lots of obviously useful applications.

Pretty sure that "colosseum" at 13:20 is Pantheon.

13:21 This is actually the Pantheon, not the Colosseum! Fun fact: It has the largest unreinforced concrete dome in the entire world, which is especially impressive for a building from 125 AD.

These scans can produce amazing wallpapers

The application of how it’s used was super cool to see. 14:23
