Therac-25 - Wikipedia
网页The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
A History of the Introduction and Shut Down of Therac-25
网页The Therac-25 case pointed to significant weak links in communication between FDA, medical device manufacturers, and their customers or users. Users were not required to report injuries to any government office, or to the manufacturers of …
Killed By A Machine: The Therac-25 - Hackaday
网页2015年10月26日 — The case of the Therac-25 has become one of the most well-known killer software bugs in history. Several universities use the case as a cautionary tale of what can go wrong, and how...
网页The Therac-25 was a linear accelerator with two modes of operation. Firstly, it could fire a beam of low-energy electrons, which do not penetrate far into the body, and are therefore well-suited at killing
网页The Therac-25 was a medical linear accelerator, a linac, developed by the AECL (Atomic Energy of Canada Limited) and CGR, a French company. It was the newest version of their previous models, the Therac-6 and Therac-20. These machines accelerated electrons that created energy beams that destroyed tumours.

Death and Denial: The Failure of the THERAC-25, A Medical …
网页The Therac-25 is a medical linear accelerator manufactured by AECL. A linear accelerator ("linac") is a particle accelerator, a device that increases the energy of electrically charged atomic particles. The charged particle are accelerated by the introduction of an electric field, producing beams of particles which are then focused by magnets.
Therac-25 - Ethics Unwrapped
网页The Therac-25 machine was a state-of-the-art linear accelerator developed by the company Atomic Energy Canada Limited (AECL) and a French company CGR to provide radiation treatment to cancer patients. The Therac-25 was the most computerized and sophisticated radiation therapy machine of its time.
