Artificial Intelligence is the behavior of a machine, which, if performed by a human being, would be called intelligent. It certainly makes machines smarter and useful. Artificial Intelligence can be linked by two basic ideas. First, it involves understanding the thought process of human beings. Second, it deals with representing these processes via machines (like computers, robots). Applying Artificial Intelligence techniques in the medical field may help not only the improvement of accuracy performance but also in saving related time and cost. This paper reviews about how Artificial Intelligence might help the society in the future.
