Lessons Learned from the Therac-25 Radiation Therapy Software Disaster 🥲

Alright, let’s talk about the Therac-25 radiation therapy machine bug, or, as I like to call it, the glitch that turned a medical device into a death machine.

In the 1980s and 90s, the Therac-25 was all the rage in cancer treatment. It was a radiation therapy machine that could be controlled by a computer, which was a huge leap forward from the older machines that required manual adjustments. But, as we all know, with great technology comes great responsibility. And unfortunately, the engineers who designed the Therac-25 didn’t take that responsibility seriously enough.

The software bug in the Therac-25 caused patients to receive massive overdoses of radiation, resulting in at least six deaths. Now, I’m not a doctor, but I’m pretty sure that getting over 100 times the intended dose of radiation is not good for you. It’s like trying to put out a small fire with a fire hose and accidentally unleashing a flood that wipes out the entire city. Oops!

So, what lessons can we learn from this tragedy? Firstly, when it comes to safety-critical software, we need to test it as we mean it. No half-baked testing, no cutting corners. We need to be thorough and make sure that our software works as intended. Secondly, we need to have safety mechanisms in place to catch and prevent errors. It’s like having a backup plan for your backup plan.

And lastly, we need to have regulatory oversight for safety-critical systems. Because, let’s face it, some people will always cut corners if they think they can get away with it. It’s like when you’re on a diet and you sneak a cookie, and then you sneak another, and before you know it, you’re eating the whole damn box. But with regulations in place, we can make sure that people aren’t sneaking cookies or cutting corners when it comes to our health and safety.

The Therac-25 disaster was a wake-up call for the importance of safety-critical software design and regulatory oversight. We can’t afford to cut corners when it comes to our health and safety, and we need to take responsibility for the technology we create. And for the love of all that is holy, let’s make sure our medical devices don’t turn into death machines.
