Have you ever wondered what’s actually going on inside the hotend of your 3D printer? It doesn’t seem like much of a mystery — the filament gets melty, it gets …read more Continue reading Looking Inside a 3D Printer Nozzle with Computed Tomography
We’ve recently got a look at how [Ken Shirriff] used an industrial CT scanner as a reverse engineering tool. The results were spectacular, with pictures that clearly showed the internal …read more Continue reading A Deeper Dive Into Reverse Engineering with a CT Scanner
The degree to which computed tomography has been a boon to medical science is hard to overstate. CT scans give doctors a look inside the body that gives far more …read more Continue reading CT Scans Help Reverse Engineer Mystery Module
It’s that time of year again — the 2022 Hackaday Prize has officially launched, and we’re excited to see what it turns out. This year’s theme is “Sustainability, Resilience, and …read more Continue reading Hackaday Links: April 3, 2022
Once you’ve built your own X-ray machine to take 2D images of the insides of stuff, there’s really only one logical next step: building your own computed tomography (CT) scanner to get 3D reconstructions instead. That’s exactly what [Fran Piernas] has done, and documented over on hackaday.io. While the original …read more
Join us on Wednesday at noon Pacific time for the X-rays and high-voltage Hack Chat!
Fran Piernas likes to push the envelope a bit with projects that others might shy away from. A quick glance at his Hackday.io profile reveals a few of the exciting projects he’s been working on recently, including a DIY X-ray machine and the high-voltage driver needed to run it. Not only that, he’s recently taken his home-brew X-ray rig to the next level – a computed tomography (CT) scanner. His YouTube channel also has some exciting stuff using potentially lethal voltages and ionizing radiation.

If you’ve ever experienced the heartbreak of finding a seed in your supposedly seedless navel orange, you’ll be glad to hear that with a little work, you can protect yourself with an optical computed tomography scanner to peer inside that slice before popping it into your mouth.
We have to admit to reading this one with a skeptical eye at first. It’s not that we doubt that a DIY CT scanner is possible; after all, we’ve seen examples at least a couple of times before. The prominent DSLR mounted to the scanning chamber betrays the use of visible light rather …read more
Health care providers and manufacturers of medical imaging devices (MIDs) need to be more vigilant when it comes to protecting their equipment, researchers from Ben-Gurion University say in a new research paper. The paper, published this month, details how researchers found that the devices are particularly vulnerable to threats that can ultimately result in harm to patients. “MIDs are increasingly connected to hospital networks, making them vulnerable to sophisticated cyber-attacks targeting the devices’ infrastructure and components, which can disrupt digital patient records, and potentially jeopardize patients’ health,” the paper’s abstract says. At particular risk are computed tomography (CT) machines because of their widespread use in acute care imaging, the researchers say. The researchers simulated cyberattacks on machines that conduct CT scans and their host computers and came away with several major risks. By gaining access to the configuration files on a CT machine’s host computer, hackers can change the way a […]
