An Investigation of Therac-25 Accidents - I
نویسنده
چکیده
Computers are increasingly being introduced into safety-critical systems and, as a consequence, have been involved in accidents. Some of the most widely cited software-related accidents in safety-critical systems involved a computerized radiation therapy machine called the Therac-25. Between June 1985 and January 1987, six known accidents involved massive overdoses by the Therac-25 -with resultant deaths and serious injuries. They have been described as the worst series of radiation accidents in the 35-year history of medical accelerators.[1]

As I was reading the New York Times at the end of 2010, the headline of a news article suddenly hit me “A Pinpoint Beam Strays Invisibly, Harming Instead of Healing – A Radiation Setting Is Wrong, and Patients are Harmed” while undergoing SRS (stereotactic radiosurgery) treatment in a hospital. As American baseball player Yogi Berra once said “It’s déjà vu all over again.” When the story first ...
متن کاملA formal framework for the analysis of human-machine interactions
There are more and more automated systems and people are led to interact with them everyday. They are also increasingly complex and exhibit more and more “smart” behaviour. One direct consequence is that it becomes harder for the human operators to drive those systems safely for both the system and the user. Due to that increasing complexity, interactions between users and automated systems are...
