content: Dear X-Ray fans,I thought I would share some pictures and thoughts on some modern digital X-Ray plates that have just come into my possession.I have four large Digital X-Ray plates that are ex hospitals. They are fully digital DR plates rather than the CR plate system. That is to say, they contain a large CCD or photodiode imaging array that has a Scintillator sheet in front of it to create an image when illuminated by X-Ray radiation.It will come s no surprise that these cost a small fortune new. Mine are all suspected faulty so may never work again. This does give the opportunity to investigate the technology however. How far i go with a tear-down has yet to be decided as you will see later.These X-Ray plates are stated as being wireless and self contained. They contain wireless transceivers that link them to the host PC that contains the image display and processing software. The Canon plates are definitely standard 2.4GHz and 5Ghz Wi-Fi with AES encryption to protect patient data. The Canon units also have an IRDA communications port that enables them to be easily logged onto the PC system as individual identifiable X-Ray plates. One PC can serve several X-Ray plates at the same time in a multi X-Ray room deployment.The Samsung X-Ray plates are also wireless but I have not established whether it is Wi-Fi complaint or proprietary. I have had no time recently to research these plates.More information when I have it, but to be honest, without the PC software I am not certain knowing the communications bearer is of much use anyway.So what is wrong with these plates ?A visual inspection has revealed the most likely faults with these plates.1. The two Canon CXDI series plates have both suffered from the diligent use of wet anti-bacterial cleaning solutions after each use. This is standard anti-bug transfer protocol in Hospitals these days. Sadly the fluid has crept past the rubber bungs and case cover and caused some not too serious looking corrosion. The external (diagnostics?) socket on the CDXI-80C is badly corroded which cannot be good for the plate. The corrosion does not look terminal however.2. Samsung S4335 plates are both the victims of physical abuse. Both have obvious bending of the case. Some detector arrays are on glass and others are more flexible so such bending may or may not mean the destruction of the imaging array. Interestingly, one of the bent plates has had its battery taped back into position so presumably it still worked after the accident ? This could also have been a desperate attempt to see if teh plate survived the damage of courseThe Cannon plates are easily disassembled by removal of many screws that secure the rear plate in place. The Samsung plates are a little more challenging to disassemble and I have yet to get into one. They do not appear to share the corrosion issues of the Canon plates. possibly due to the more watertight construction that makes disassembly paths less obvious without damaging the front or rear plastic covering.None of the plates rattle when give a good shake so no shattered glass insideThe canon units are equipped with glass plate detector arrays but are rated to be stood on by the average human adult !So what to do with these plates ?1. All except the CDXI-80C are too large for use in my Faxitron MX-20 and the 35kVp maximum voltage on the micro focus tube may not be enough for these plates either. They are designed to work with a tube running around 75KVp. The plates are self contained in that they self trigger upon exposure to X-Ray energy and have their own auto exposure system to obtain the best image. The complete images are then sent to the host PC as a file for display and user manipulation. I suspect the file sent is a Dead Pixel and Non uniformity corrected ADU data set that the PC manipulates as required.2. Ripping these plates down to their component parts might be fun and interesting but I hate doing that if others can make good use of them. The canon plates look repairable. Even the Samsung plates may still function well if they do contain a flexible imaging array and can be flattened with some careful metal 'bashing'3. I am unclear whether the data emitted from these plates may be decoded and viewed without the original PC software that is very expensive. Ift might be interesting to see if one of the Canon plates can be repaired to see if communications can be established with it. there is also the diagnostic/hard wired port to explore on all of the plates. Hours of fun for someone maybe ?4. Am I going to use these plates for X-Ray ? Unlikely as I have no need of such large X-Ray images at this time. The smaller CDXI-80C looks more useful but it i still quite large.So what next I wonder ? I welcome thoughts fro m the readership but please consider my comments above. It seems sacrilege to tear down a £10K+ wireless Digital X-Ray plate for pure curiosity when someone else needs such for more serious work. It is not like I do not already know what resides inside the plates design. It is the same technology as used in many digital X-Ray plates and cameras that I have seen described in great technical detail.I hope the pictures are of some interest and maybe we can come up with some ideas on what I should do with these lovely bits of X-Ray imaging kit ?Before anyone suggests I set to an repair them.... I am not sure that I have the time or enthusiasm to do that at the moment. A recent loss in my family has robbed me of enthusiasm for very much these days.If anyone wants these plates for serious use please let me know and we may be able to do a deal. Sadly I cannot give them away for free as they owe me some pennies.Fraser

content: I missed out on a similar one on ebay quite a while ago.They would be useful for use in conjunction with a dental head, or something like my mailroom scanner - would be interesting to see if they can do better resolution.As regards getting them running, I think my approach would probably be to ignore the wifi stuff and find some internal sensor signals & interface to those.My guess is they'll have an x-ray sensor to trigger them automatically when exposed. ( photodiode+scintillator).With luck maybe they can transfer an image to internal memory before/without dealing with any protocol to an external system beforehand. If this is the case it may not be too hard to extract the data somewhere during that process .Would definitely be interested to see further inside to see what the electronics look like. I wonder if they use a standard sensor plus their own interface electronics - could be a documented interface between the two.

content: Mike,I will take the covers off of the Canon plates as they are easiest to open. There are cable contacts on all of the plates for hard wire connection but, as you say, we need to better understand the internal design.Whether you have to arm the plate over the Wifi or IRDA link is another question. The plate stores the last collected image for repeat downloads which suggests it probably has to be told to erase the stored image and arm for the next.Internal pictures soon.Fraser

content: Mike,The Canon PC software user manual is available for download. I shall take a look at its contents.In the mean time.... as you requested...... internal pictures of the larger of the two Canon plates. This plate looks to be in excellent condition and may even work ! I expected the same corrosion as found in the smaller plate but none visible. I will charge the battery and see if the plate comes up with a 'Ready' light.Now the pictures. I had to compress them to fit them into this forums restrictions. better detailed images can be uploaded at 2MP resolution.the electronics are nicely spaced out in this large plate. Much less crowded than in the smaller plate. The various parts are easily identified including the H and V mutliplexers and associated concentrator board.EnjoyFraser

content: getting them working would be the ultimate hackaday project.even if you don't need such a large imaging area now, it's nice to have it available if you ever do.i think your 35kv x-ray source will be your primary limiting factor though.at least at the hospital nearby the problems they seem to have with these mostly stems from the batteries. they are designed to take a lot of abuse from clumsy technicians.

content: I do have a nice Gendex Oralix 60 Dental X-Ray head but the is not supposed to illuminate such a large area. It has 60KVp on the tube.To be honest I am not that interested in large target X-Ray imaging. All my needs are met by the little Faxitron MX-20 120mm x 120mm digital plate.If I get one running I suspect I would just move it on to someone who has a use for such a plate. I may just move them on as 'projects' as my spare time is very limited for such a project.Fraser

content: This will probably sound stupid, but, is there some kind of X-ray shield plate between the sensor sheet and the electronics behind it?Or are the expected X-ray intensities too low to have any effect on the electronics, flash memories, etc?[ Edit: ha ha, otoh, maybe putting firmware in unshielded flash in an X-ray imaging device is a new kind of planned obsolescence? ]I hope you or someone can get them working. For one thing, you could take X-ray shots of larger bits of electronics like laptops, phones, tablets, etc.LCD screens even, which seems pretty funny considering these look like LCD screens (with blank faces.)Sorry to hear of your loss.

content: I recently tore down a large-ish digital imager, and it had a ~3mm sheet of lead directly behind the sensor. Said sensor being essentially a reversed TFT monitor, with photodiodes and read-out circuitry patterned on a sheet of glass. Which was connected to the motherboard via 60 individual FFCs...Do be careful with the sensor, though - mine had a Cesium Iodide scintillator layer which was (supposedly, anyway) doped with a couple grams of thallium. Nasty stuff. As long as you don't break the hermetic sealing foil over it, you should be fine.

content: Ow. Thalium. With a couple of PM tubes with (iirc) KI-Thalium-doped scintillator blocks around here somewhere, I'd read up on Thalium risks. I'm amazed anything with Thalium in it can be marketed at all, let alone WITHOUT extreme safety warning notices all over the device.I second the 'be careful' comment. Don't puncture the containment. Just don't.Note the scintillator material is sealed from air because it's deliquescent - absorbs moisture from the air. Also creating a Thalium transporting goo.https://www.ncbi.nlm.nih.gov/pubmed/6338655Thallium poisoning: a review.

I have spent my fair share of time in hospital and the staff are always highly amused that I am so interested in looking at the equipment surrounding me and wanting to watch it 'in action'.Some people hate the MRI machine because it is quite enclosed and 'booms' when operating....... I love it ...... listening to the different frequencies as it carries out the scans. I think I must be a bit oddAt my last MRI, just as the scan was about to start, I noticed a tube was disconnected from the acoustic communications interface. The nurses were surprised I had noticed it but fortunate that I did as that was the control room communication line to me to tell me to stop breathing during the scan.I had an endoscope inside me once and, though sedated, I still managed to ask the doctor for a printed picture of the investigation site. He kindly obliged and even described what the picture was showing. The nurses were laughing as most patients are more concerned that there is something wriggling around inside them and the last thing they want to do is see what the endoscope is seeingFraser

I gave my word early in the peace that the effort they the doctors and nursing staff went to whilst I was in trouble won't go wasted and I will now make every possible effort to stick around, you buggers will just have to suffer a bit longer.

content: Likewise Muttley, best wishes. The main thing is that you have a diagnosis, you're bound to be better under treatment and monitoring that you were, wondering around, ticking!Quote from: Fraser on May 09, 2017, 11:00:00 amNo you're not alone, me too!There's something quite 'cosetting' about being enclosed in a nice warm tube, listening to all the scan patterns, some of them are quite hypnotic (although there's one particularly deep one on mine that shakes the table). The only problem I have is the pressure of the sensor coil on the tip of my nose (big nose!), but once you get used to looking through the plastic mirror rather than going cross-eyed it's fine. They've just upped their noise protection policy at my hospital - now you get ear plugs aswell as the piped headphones.I always buy a copy of the scans on CD, nice to see the pretty pictures ahead of the consultant appointments and the individual scans show the TR, TE etc. parameters that you can relate with the sound effects.P.S. You want to try cystoscopy. Once you get past the 'cross legs and clench' urge as the three eyed snake (RGB) approaches your tender parts you get to see some very pretty high res pictures without being hampered by the sedation.. Having had both, I much prefer the cystoscopies!

content: Good luck Mutley, hope your problems can be completely fixed.Gyro: "I always buy a copy of the scans on CD, nice to see the pretty pictures ahead of the consultant appointments"Interesting that you have to buy them. Here in Oz (and Philippines) all images and videos are always given to the patient. That's been my experience anyway, except one instance where it turned out the doctor was deliberately avoiding me having the images, for reasons to do with a malpractice drama.Cystoscopies are interesting. During one (in Philippines, again related to the malpractice stuff) lying there watching the video (which I have on CD) I had fun by teasing the theater assistants. Long time ago I played around a bit with bio-feedback. Learned to consciously change my heart rate. So, in the theater I ramped it up without warning them, had a laugh at their panic, then showed them I could wind it up and down at will.Fraser, I too enjoy MRIs. I couldn't relate the different scan sounds to the various imaging modes since I have no feedback of what they are doing at any moment. But it's an interesting sound, and the confined tube doesn't bother me. Nothing as tight as some places I've been caving. After one MRI the operator asked me how I was feeling. "Very precessed." He laughed.

It's a fixed price though, so you can get every X-ray, MRI, CT etc that you've ever had on however many CDs for the same price. Of course I take the 'sucker' approach of buying the latest MRI each time, which is about half a CD's worth. I don't mind though - it's a bit of extra cash towards the hospital funds in exchange for 5 minutes work by the IT office.P.S. Quite a lot of the time the situation would be getting the scan done using NHS hospital facilties for referral to a private consultant, in which case the insurance company would pick up the bill anyway. It's only us 'health nerds' who actually pay the cost.

I often take on projects where I find out, oh this easy or there is no way in hell I'm going to figure this out. Makes for a lot of spare parts I'll never use. I'm still trying to find that in between state, but its like science articles on the internet: they are so dumbed down you learn nothing or its a 40 page dissertation with math that goes way over my head.

content: It depends. Maybe some poking the ethernet might get a response.One thought was that if these are set up to switch on and take an image (triggered by x-ray detection) without having previously talked to anything to 'arm' it, then it might be feasible to tap off the datastream from the ADCs as they read the data into internal memory.Maybe it saves files to the internal RAM of Flash that are read out with some standard protocol.There may also be some sort of test interface over telnet etc.And I bet there's a UART on the accessible connector.Wishful thinking maybe, but plausible I think.

The Canon plates use IRDA for this, Samsung may have used RFID. those vials certainly look like the RFID tags I have used in the past.from memory all of the plates were wired or Wireless in order to meet a customers needs.

All 4 red on one, 2 of 4 in the other.Just put some charge in the battery, and "Power" and "busy" light for about 10 secs (e.g. small linux boot time), then busy goes out.I would expect that if it was not in a state to start an x-ray, there would be some clear visible indication.Thinking more about it - you never want to x-ray someone more than necessary, so I can't see any reason why it would not always take and store an image if x-rays are detected - you wouldn't want to have to re-expose the patient if teh operator forgot to set up the plate.Too tired to play ATM, and probably too busy for the next few days.What was disappointing was the lack of an obvious seperate x-ray sensor that coule be used to fake triggering, tough I wouldn't be surprised if one of thise buttons does it for testing. I've not had the PCBs out yet - could be a photodiode on the underside.

content: @Mike,Damn, with those shock detectors indicating red I suppose the warranty on the imaging array is voidBut seriously, these plates endure quite a rough life so I am surprised that there are shock sensors needed. The plate should be adequately buffered to protect it. Sounds like a manufacturer keen to have a reason to refuse warranty service ! IIRC the smaller plates cost £10K and the larger ones, a lot more. Imagine breaking one that you had bought with your own hard earned money (people like VET's also use them)Many OEMs of these plates sell the end user a support contract at great annual cost. I can now see why the end users have to cough up that money as these plates are a serious investment and you do not want the OEM declining service due to 'abuse' by your staff.I hope these plates give you some enjoyment Mike. They were way too large for my needs and hacking them to operate is beyond my skill set. It would be great if you could source the PC software for the Canon plates, or even an engineering test software. Worth contacting Canon ? From what I understand, the PC just connects to the plate via Wi-Fi and whenever an X-Ray is taken, it parcels the image up and sends it automatically. If another download of the data is needed it may be requested.It may well be a FIFO system where a new exposure pushes the old one out of the memory ?By the way, I am impressed with the image coming out of the Fire FLIR camera. Love it. It has gone to a good home with meThank you for your kindness and generosity today.All the BestFraser
