Love the timelapses! I'm also surprised by the teardown's lack of ingress protection, in the medical setting those are often placed under patients that are leaking fluids and in the industrial environment those are usually used in very dusty and often wet building environments, surprised how clean this unit was inside given that, I imagine this one is non-rugged intended for clean lab use? I’m impressed you were able to even obtain the software for the sensor, most medical devices end up as e-waste because you can’t get the software or physical licence dongle. I’ll also mention just be careful with those cheap SBM-20 Geiger counters, they’re useful for finding high energy radioisotopes but they come with a lot of measurement caveats, they’re not very sensitive to < 50 keV X-rays, are prone to reading 0 when saturated and CPM to dose conversions are only accurate for their calibrated source (usually Cs-137 or Co-60). However, you’re clearly taking good safety measures with remote triggering and such.

[@AppliedScience]

This device came with an additional outer carbon fiber enclosure for use in harsher environments, but I agree: I was also expecting more waterproofing, etc. Thankfully, Amir also supplied the software/laptop. Each instance is locked to the detector MAC, as well as the computer's MAC, and will only transfer images when both MACs are identified as source and receiver! I tried a few different ways of getting around this before obtaining the whole setup, and was not able to get anything out of the panel. I had originally been port scanning it with no detectable open ports from a MAC that was not whitelisted. Originally, I had planned to make a video about trying (achieving?) a way to make it work without the proprietary software. I should probably do it, since I now have the working setup, and can sniff the traffic, which I couldn't do before, and was ready to give up trying to randomly guess the protocol. I've seen the geiger counter saturate, but it takes *a lot* of radiation :)

When was working on radiotherapy software 15 years ago I remember one such panel was $150k+. They seem much more 'affordable' now with one less zero at the end. A good catch you got there. I'm wondering how heavily the phosphorous layer is bonded and if such a panel could also be used for a very sensitive telescope

[@WhileTrueCode]

the scintillator might be bonded pretty well.. some manufacturers grow the cesium iodide crystals directly on the TFT glass in a hermetically sealed encasement. the crystal to photodiode coupling is one of the biggest determining factors for image quality (and price)

Why is it that as the price of the hardware goes up, the quality, features and usability of the software always seems to go down?

(Maybe that's it: the big-ticket hardware is built by hardware developers, not software developers and they end up Dunning-Krugering the software? They literally can't tell the difference between usable software and the BS they shovel on the customer's head?)

[@kissingfrogs]

Thank you Amir. Counting child-windows may be of interest - maybe not relevant for this task however. To cludge automate industrial apps (Siemens LCT) I have counted the number of child-windows (using VB3) spawned to determine the right time to send the next sequence of keystrokes. Time taken for a child-window to spawn varied greatly in my use case and dependant on the network of the very remote devices and detecting when a child-window spawned ensured maximum thru put rather than coding for worst case. It tuned an ~ 60min task into a 1 minute setup and run and walk away task. (Also took me about 3 weeks to get to that point)

There is no reason they can't declare it unusable for medical reasons and sell it to folks like you. This is awesome!

[@nrml76]

Very interesting to see the tear down of a device we see in use in hospitals daily. In the hospital setting, these devices are the sensor part of portable x-ray machines. For example, to take a chest x-ray of a patient who can't get out of bed, the plate is slid between the patient and mattress and the the x-ray tube part of the machine is wheeled over the bed and the image taken. Before wireless connections became common place, the radiographer would take it back to the radiology department where the image would be downloaded off the device and loaded for viewing on the imaging software used in the hospital. Some of the connectors are probably there to ensure that there is manufacturing commonality so that it can be used with minimal modification across the different models of portable x-ray machines produced. The sensor plates are very robust and take an awful lot of abuse. They get drenched in everything from blood, vomit, urine and worse. These plates are used for static images. C-arm image intensifiers are much more powerful and can do both still images and live fluoroscopic imaging. Can you get hold of one for a tear down?

[@AppliedScience]

Yeah, I'm always torn between making hour-long videos with all the details, and trying to keep things lively at 20 minutes :) In this case, after running the timelapse sequence for several hours, the software would randomly fail, and when I came back the next day, I would see the program had to be restarted in order to get it working again. At some point, I was lucky enough to catch the failure in the act -- a modal dialog would pop up and indicate "failure to transfer image". If the dialog was ignored (as it would be by the mouse control script), the software would never regain itself, and no further images would be acquired, but upon the next frame acquisition, the dialog would disappear yet the whole software stack would remain in a non-working state! I got around this by always right-click and closing the "image acquisition" part of the program, which didn't cause a problem in the normal case, but also was sufficient to acknowledge the model dialog in the failure case... They should pay me for QA testing. There were many many other bizarre quirks -- my favorite: The ad-hoc WiFi password is hardcoded and printed in the user guide. The password is 26 1's.

These DR cartridges usually go into a slot on mobile xray machines to be used for mobile/emergency xrays, predominantly chest or abdomen. also, they usually have shock detectors which record any impact and log the time/date, to be able to track back to the operator.

[@vizionthing]

I cannot imagine any of us complaining that the video is too long!

[@theofficialczex1708]

That time-lapse of the camera zoom is art.

[@A.Mere.Creator]

Time to watch this whole video and pretend to understand what he's saying. And you were right, I have not seen anything quite as amazing as this 1:50

[@nefariousyawn]

I suspect you aren't the same Amir that sent him the x-ray setup?

[@A.Mere.Creator]

@@nefariousyawn lol no but I got caught off guard when he said it

[@bucky13]

There are times where I think I'm clever, slick, reasonably intelligent.. Then I watch your videos and realize I have an entire lifetime of learning left to do.

[@Pixelarter]

Suggestion: when you do this type of stuff, show the end result (in this case the timelapses) at the end of the video again. It puts context again to everything you explained, makes watching until the end more rewarding, and brings closure to the video. If it's too much stuff, show at least the better one.

[@andrewwalsh3744]

Your dog'ed determination, array and depth of talents and intellect always leaves me transfixed; just love your applied science.

[@Pants4096]

I wonder if the root membranes actively block or take up different salts, and therefore actively took the water out of the solution leaving most of the KI behind?

[@Duffman-zn7ku]

This is why i love this fucking channel. Wanna see fluid movement through plants? Great! Here's the footy and a 20 minute, granular level, electrical engineering lecture on how xray tubes work and how the digital xray sensor captures the image.

[@efkastner]

Thank you Amir!

[@maxk5065]

timelapse is always satisfying but Xray timelapse is a new level to me. thank you for your work

[@needamuffin]

I'm curious as the why the whole thing is portable. If it was a part of a unit that came with an emitter then it would make sense, but it looks like you had to supply your own. Also, that shot of the camera was amazing. I'd be interested in seeing more mechanically complex machinery move under xray.

[@Rashombo]

I would think it is a portable sensor for use in emergency rooms where the patient cannot be moved because of their trauma.

[@123dada456]

You can buy from the same manufacturer x-ray emitters. They are even portable. Usually used to inspect pipelines.

[@zaliman]

I've seen vets at zoos use them to do in field x-rays to rule out having to put home under as and bringing to OR

[@ikocheratcr]

Modern XRay machine use this type of table as the "media" to capture. It is "portable" so doctor does not need to move patient, the emitter moves, and then this unit is placed in the "right location", and the say whisky.

[@fischX]

Maybe it's a legacy implementation for older x-ray stations? The form factor is somehow similar to film cartilages that where in use before the digital age.

[@mariodistefano2973]

There's ALWAYS A TON of things that can be learned by watching your videos... Several times in my life I've been in front of unknown devices like this one you get, but always get stuck at some point. Maybe my inexpertise, ignorance, or whatever... But I admire your capability to go on (with a bit of luck) into unknown fields. CONGRATULATIONS!

[@shreyaskul]

This is awesome Ben! The efforts you put into these videos is incredible :) Also I think the batteries must have a I2C EEPROM in them for serial ID and to stop counterfeit/incompatible batteries to be used. You could remove the EEPROM from the dead battery and just hard wire it dead-bug style on the main board. Or better way dump the data from the EEPROM and flash a new chip.

[@Jtretta]

I've seen these at the hospital I worked at a little while ago. They slot into a charger holster on a self contained x-ray station that can be rolled to the patient. Super cool to see one taken apart!

[@drew6017]

9:41 if its written in c I'd bet there is an image acquisition function somewhere. Even if it isn't there is native code somewhere which you could theoretically pattern scan for. You could then do a dll injection and from that dll call the acquisition function directly. Then its just a matter of ipc to link this to your existing setup. helpful tools for reversing: detect it easy cheat engine ida pro (or other dis.) It would be a lot of work, but it would also be pretty cool. edit: also, I love this project your great

[@evil-wombat]

Yeah there's gotta be a DLL somewhere that does the heavy lifting in an abstract way. Maybe even an ActiveX control if they went that route. But since it's network controlled and spits out raws of a fixed size, I wonder what it would take to reverse-engineer the protocol and write your own software. With any luck, it doesn't require you to remotely bootstrap the FPGA over the network, though that wouldn't surprise me. Either way, Wireshark is your friend.

[@benjaminknudson5997]

best online video publication of the year, give him the award already.

[@michaelzoller9884]

Great video! Has histogram stretching or contrast enhancement / sharpening been applied to these images? Working with CT image processing, I have learned that this can make a big difference in image quality.

[@beauxtx1959]

As a radiologist, I found this absolutely fascinating. KUDOS!

[@bongsgi95]

Hey Applied Science. I’m working on a simulation of plant growth, which involves water and sugar flow inside the plant as well as cell divisions bases on hormones - the whole shabang. It’s a tough problem especially without any real-life reference, so I was wondering if I could somehow get my hands on your video for some Python analysis. It would be truly helpful to know how water is transported throughout the plant, and I’d love to share my resulta with you!

[@KallePihlajasaari]

Good proposal. If he does not see your request it is worth spending the penny on a Patreon subscription to send him mail that is more likely to be read.

[@bongsgi95]

@@KallePihlajasaari that´s a really good idea and well worth the money. Everything he does is amazing!

[@coder0xff]

I don't know which is more interesting, the timelapse of the plants or the sensor. Both very cool.

[@LimabeanStudios]

I would just like to say this comment section is always one of the best on youtube. So much experience in so many different fields coming through.

[@ADR69]

Thanks Amir!

[@rkond]

This brings back some memories. My first job 20 years ago was developing the software for an XRF microscope. This is a kind of software I would expect for such device.

[@ShainAndrews]

I have a feeling ports are disabled by default. Has to be some sort of admin or debug console to enable them. Can you imagine being the person that damaged it? Could have been some simple bump on the corner of a table... and it's dead.

[@liamharrison3]

Guessing from the Gbit link there are some applications where it spends a lot of time docked that way.

[@WrinkleRelease]

Thank you, Amir! Ben, I love your channel. You’re the adult’s Mr. Wizard.

[@nigeljohnson9820]

Two days ago I was siting in front of a panel very similar to this one, having my kidneys X-rayed. At the time I was very curious to know a lot more about how these panels work, particularly, how the imaging was preformed, the sensors involved, and how the data was transferred from the portable panel to the computer system. The hospital computer network is such that X-ray images are available between departments, and ever other hospitals, within minutes of being taken, as well as being stored as part of a permanent record, somewhere on a cloud server. I would be interested to know a little more about the WiFi interface. How the WiFi addressing and security protocol were set-up on the panel, presumably this was via some serial interface.

[@nigeljohnson9820]

When i was x-rayed, an iodine based dye was injected into my blood stream, to make my organs visable, just like the plant. Fortunately wilting was not a side effect, unlike the poor plant.
