The medical ultrasound scanner reveals its secrets and launches DOOM
Medical equipment often results in interesting teardown videos: the strict requirements imposed by certification bodies mean that you will find good quality components and a high standard of design and manufacture. But when [Buy It Fix It] bought an ultrasound machine on eBay, he wasn't interested in taking it apart: his plan was to use it to find out if his sheep were lambing, so he kept taking it apart. repair and modify it. for his new purpose.
The device in question is a Mediwatch Bardscan II, which is intended for use in scanning people's bladders. The motherboard, however, has a completely different model number, suggesting that the basic design is used for several types of ultrasound scanners. The system is powered by an AMD Geode processor that runs Windows XP Embedded stored on a CompactFlash card, so examining the internal software is easy: the scanner interface works even on a standard Windows PC.
Several files on the internal drive point to hidden functionality, with filenames like kidney.dib and liver.dib indicating that the instrument can scan more than just bladders. The reader also contains several versions of the scanning application, as well as an .ini file where many features can be enabled or disabled. By running the executable through x32dbg, [Buy It Fix It] was even able to recover the password to enable the "Advanced Settings" menu - it's "u10" in case you were wondering.
With a bit of file editing, [Buy It Fix It] managed to turn the rather basic system into a much more flexible ultrasound machine. For example, he can now adjust scan depth, replay previous scans, and take notes on all captured images. He can even perform DOOM, as he demonstrates at the end of the video - although we can imagine his sheep might not relish the sight of their owner approaching them with a box full of flamethrower demons.< /p>
Medical ultrasound machines, which have been around for a long time, may seem like complex machines, but it is possible to make a simple version with readily available components.
