A Short History of the Gastrointestinal Capsule
摘要
The origin of work on the gastrointestinal (GI) capsule can be traced back to 1981. At that time, I was on a sabbatical leave from my work as an electro-optical engineer at Rafael, a government defense lab in Israel, and was working in the United States for a medical instrument company in Boston, Massachusetts. A gastroenterologist friend, Prof. Eitan Scapa, explained to me some of the shortcomings of the fiber bundle endoscope, especially its rigidity and its inability to view the small intestine. At that time, I had no idea as to how to solve these intriguing and interesting problems.
