Medical Device Software Safety — Lessons from Radiation Accidents

Thank you for watching this video from Medical Software Consulting. This presentation explains the infamous Therac-25 radiation therapy accidents of the 1980s—software-related incidents that shocked the world. These accidents were not merely the result of programming errors; they raised profound questions about system design, organizational culture, and the role of regulation in safeguarding patients. In this video, we review the sequence of accidents and their causes, and show how today’s international standards have incorporated these lessons. We also go a step further, analyzing the software architecture of the Therac-25 and exploring how it might look if rebuilt using modern design techniques.
