Building a DIY CT/CAT scanner for 200$

Bravo my friend! I was in medical school in the 1970’s when the first CT scanner was developed by the engineering branch of EMI Limited in London, England. They were better known at the time as one of the four largest music publishing companies in the world. I believe at one time they owned the rights to the entire Beatles catalogue. I spent 41 years doing general surgery and, without a doubt, the CT scanner was the most useful of all the technologies in my medical toolbox. Originally it was only able to perform brain imaging and the scans were quite pixelated but, of course, the technology rapidly improved and eventually it was applied to all parts of the body. In the space of about a decade, “exploratory laparotomy” (opening a patient’s abdomen to find out what was causing pain, infection, obstruction, bleeding, etc.) became nearly obsolete. Currently a surgeon generally knows a lot about what he/she will find before the patient ever reaches the operating room allowing for careful preplanning of the procedure. I recall many exploratory surgeries early in my career where there were at least a half dozen possibilities going in. Surgeons had to essentially be ready for almost any eventuality. This forced a very rapid assessment, diagnosis and treatment plan while the surgery was in progress. This was exciting to say the least but also very stressful. It is rare nowadays to be in that sort of situation, though it still sometimes occurs when a patient’s condition is too unstable even to perform a brief CT scan. Excellent work young man. When I read the title of your video, I thought perhaps you misunderstood the complex nature of the reconstruction algorithm. Turns out I was the one trying to keep up with your explanations and logic. Sir Godfrey Hounsfield shared the Nobel Prize for his work in developing computed axial tomography, perhaps one day you might help invent some new technology to make the world a better place. I’m rooting for you.

@@gregorymalchuk272 they are mostly proprietary and sold with the scanner by companies like GE, Siemens, Toshiba, etc. most are about the size of a home refrigerator though I don’t know if most of that is taken up by memory modules. That’s why I was skeptical that the KZbinr could perform the spatial reconstructions using a laptop, but he proved me wrong. What’s more, this was just his initial attempt. He could refine this significantly using an old microwave oven with rotating platform as was suggested by another commenter.

[@Steelplayer59]

Absolutely incredible that this works as well as it does. After working 4 decades in control systems, I would recommend programming at least one more additional button on your remote - an E-Stop (emergency stop) button to instantly halt the x-ray and high voltage power supply, should someone (or possibly a pet) enter into the area unexpectedly. Impressive that you researched this so completely. Well done!

[@nasiriyah110]

I fix CT scanners for a living. This is pretty darn cool!! When you started out, I was trying to figure out how you were going to make all of that rotate around your “patient.” You simply rotated your “patient” itself. Well done! You need to get into this business!!

[@spr00sem00se]

Excellent. I've not watched all of it carefully so you may have addressed it. Be careful to not overheat the tube. They are normally submerged in oil and temp controlled. And buy yourself a digital dose meter. Don't mess around with xrays and cancer.

[@bilinguliar]

Your beeper code does not give enough time for LOW. It does HIGH for a second, goes to LOW and immediately back to HIGH. What you need is another pause after the LOW.

[@jhyland87]

[@ame7165]

even better is to just use PWM. the atmega's default clocks put all of the PWM frequencies in the human audible range, so you can just set PWM to 50% duty cycle, wait one second, then turn it back off. no need for a loop. example from memory: (it's been a minute since i touched an arduino so double check the syntax lol) // i believe this is one of the PWM pins, and i think it's in the low kHz range int beeperPin = 6; pinMode(beeperPin, OUTPUT); // beeper on. this is 127 of 255, so 50% duty cycle square wave. (and it's 255 because it's 8-bit, and that includes 0, so it's 256 total) analogWrite(beeperPin, 127); // let it beep for one second delay(1000); // beeper off analogWrite(beeperPin, 0);

[@Emiko1]

The piezo buzzer not staying on for the specified time is because you need to delay after setting the pin to low, otherwise the code loops then immediately sets the pin high again, not giving any time to stay off, if you want a period of 1 second high and low then you can do that but if you want a total interval as 1 second so time it takes for the buzzer to go on and off then repeat, you would delay for 500 ms after setting pin 2 high and then after setting pin 2 low delay for another 500ms. Feel free to tweak these values to achieve what you’re looking for. May i recommend HIGH for 1000ms & LOW for 500ms

7:25 It's probably been mentioned but the issue with the buzzer staying on is that it turns off at the end of the loop cycle, but then immediately starts the cycle over turning itself back on. doing something like "buzzer on, wait 500ms, buzzer off, wait 500ms" would produce something similar to what you want.

This is a great idea for making your own X-ray inspection equipment; welding, solder balls on BGA components, failure analysis, etc.. It was smart to use the remote control to keep away from the X-rays! If you don't know Matlab, it's not that bad. You can use Octave and get up to speed with Matlab for free (nearly the same). Python also has LOTS of tools, but Matlab is great for doing this vector math in real time though.

[@davidconner-shover51]

hence, why he was across the yard. BTW, I helped build a general medical scanning facility once, the Xray and CT scanner rooms were lined in lead along the sides. the MRI room was lined in copper sheeting

[@hullinstruments]

Scrap yards. That's where I find my x-ray machines and I've even found a CT and other more niche machines. With the older ones just be careful about the pcbs in the high voltage oil Buddy of mine runs a local industrial salvage yard, but they also take just general scrap from the public. Not many people allowed to look around in there but he lets me come in whenever I want. I bought a half a dozen x-ray machines over the last 4 or 5 years. Some of them old nice film types, some of them super modern Siemens digital wrap-arounds. You can find a scrap yard and make friends, you'll definitely get some X-ray and medical stuff from time to time... But here's the key... You need to find out who the clients were that brought it and talk to them. In my case it was a guy who owns a business repairing, setting up, and brokering all types of machines like that. So he gave me a heads up when he was bringing the remains of a CT to the yard. That way I could get it before it hit the ground and receive damage. you'd be amazed what kind of stuff comes in these scrap yards. The smaller family-owned yards are usually the only ones that will let you come in and buy. But a few boxes of cookies and a polite attitude... And they'll keep your number on their desk and call you when certain things come in. A lot of corporations have bought out so many of the small scrap yards and they won't even let their own employees buy from them because of the liability. So you have to find a family-owned or smaller scrap yard. I pay around $0.05 per pound which means I got those x-ray machines for between 15 and $25 according to their weight. Some of the smaller scrapyards might not have a portal scanner or monitoring system. Basically that type of system is something you would find at airports, customs, and a tractor trailer weigh in stations. It's a super-sensitive scintillating Crystal detector probe and a radiation monitor with alarm. You can pick them up on eBay from time to time for pennies on the dollar. At the very least I would get a good Ludlum m and a good sensitive scintillation probe detector. Because scrapyards can get some really spicy things from time to time and they might not even know it. I've got a collection that includes some really spicy things. One of which my scintillation probe started singing and freaking out when I was more than a half a mile away from the yard. I guess it helps to be near Chattanooga Tennessee and just right next door to oak ridge national Lab. That's not necessarily were some of the radiation sources came from, but due to the huge history of radiological events and development around here... The stuff just seems more prevalent. The spiciest thing I ever foundis something similar to what I mentioned above. It is in a 5-gallon bucket with LED flashing wrapped around it about 6 in thick on all sides. That is submerged in a 50 gallon drum of water and kept in my storm cellar away from the house and underground. So yeah spicy to say the least and I was very lucky to find something like that and prevent my buddies or anybody else at the yard getting exposure. This is happened multiple times with similar situations. Sometimes not so spicy but sometimes super hot and scary. Calling the proper authorities and people with the experience to remove stuff like that... A lot of times they will come and check it out and unless it's something weapons-grade or something truly truly dangerous they won't even confiscate it. Although they will find the yard for not having portal in area monitors. They're more interested in getting the tag number of the dude who brought it and all the pictures taken by the yard so they can track them down and see what else they might have.

[@markmalonson7531]

This is great wow. Question what about radiation cell damage from exposure to x-rays is there shielding etc?

[@mapleleaf4ever]

That was friggin' mint! Well done with a budget. I'd say you got better than $200 of image quality as that looks about as good as some airport scanners. lol

[@blacklabel6223]

Incredible! I wonder how much more accurate it would be with tiny increments like 0.4 degrees per image. How much radiation do they emit? I wonder how long before it would “damage” a person. I’m also imagining if you built a slow revolving almost circular train track, you could have the hardware rotate very slowly and work well. If you had a vertical track on a wall, a patient could stand against a wall while it moved up in 1ft increments and revolved slowly. Obviously very slow and crazy work to develop but it would make ct machines an affordable household appliance.

[@seeigecannon]

Great video. I have some code suggestions though. Note: this is not in any way intended to be a roast. First, as you are in a very agressive enviroment where you can get random bit-flips, you should add a watchdog timer to the code. This is on the hardware where if a function isn't called for too long it assumes the MCU crashed and it will reboot it where you can re-initialize all of the outputs into a safe state. Second, your code is very slow (as in one loop will take many minutes) because you have a lot of blocking code (a delay(1000) will have the execution sit there until it is finished with that line). This makes it difficult to react to any other inputs you may want to add later (like a cancel button). Instead, you should have something more like this pseudo code: #include //real code, needed for watchdog setup( wdt_enable(WDTO_2S); // Real code, Enable the watchdog with a timeout of 2 seconds ) loop( wdt_reset(); // Real code, Reset the watchdog if this isn't called before 2 seconds then the arduino will reset itself if(startButtonPushed || motionRunning){ //see if the enable button has been pushed or if the program is already running if(!motionRunning){ //check to see if motion is already running to initialize the running variables (pushing the start button again doesn't do anything) startTime=millis(); //read current time motionRunning=true; //tell the program it is running angleStep=360/destiredResolution; //save a variable so the program knows when it is done currentAngle=0; //reset this counter } } if(millis()-startTime>=1000){ //here is where it gets good. The arduino is running the main loop as fast as it can (many thousands of times per second), this checks to see if one second has passed, if it has then it will do stuff takePicture(); //call function to tell camera to take a picture moveTable(); //start table motion startTime=millis(); //record new time currentAngle=currentAngle+angleStep; //update table rotation position if(currentAngle>=360){ //check to see if a full rotation has completed, if it has, shut down the program motionRunning=false; } } if(stopButtonPushed){ //having non-blocking code allows a stop button to be constantly checked motionRunning=false; } } If you have any more questions I can help out and would even be willing to make something that actually compiles. Keep up the good work.

Hmm curious how the crazy phone image AI that they use to improve the image interferes/helps. If it’s possible to find an app that turns off some of the magic would be good to compare. During scientific things it’s best to remove as much of the magic and apply it later, especially because it can vary from shot to shot. Also if you add a counter or something that was visible in the image it would help to map the particular degrees of a shot. Probably the best move is to integrate it with a Pi or something so you can correlate the shots with the actual data on rotation.

You've got your beep in a loop so its going to happen 45 times. It seems to be 'staying on' because there is no delay between the switching off and the switching on. It goes on, waits for a second, goes off, then it changes the value of 'i' and does a check, once that check is done it instantly goes back to the 'switch on' instruction. The time it takes to switch back on is imperceptibly short. It will perceptibly stay on for 45 seconds and then turn off and continue the rest of the code.

[@gnomeprints]

Being technically competent at such a young age is great, you have serious future potential. Since you can produce X-Rays might I suggest an application other than imagery. Try to develop a receiver antenna that would convert X-Rays back into electricity similar to a solar panel converting photons into electricity. Space travel has a problem with cosmic rays penetrating the space ship and damaging the astronauts, like being under constant X-Ray bombardment, current shielding is insufficient. Astronauts during Apollo missions kept seeing flashes of light even when their eyes were closed, those were cosmic rays hitting their bodies. If you can convert X-Rays into useful electricity before they penetrate the ship that would save astronauts lives & produce power for Plasma engines. It is worth the research. X-Rays are different frequency than gamma rays but the approach should be similar. Gamma rays also come from nuclear waste, an antenna encasing nuclear waste would become a battery that last for centuries and worth a Nobel Prize.
