The increase in computing power has helped in the advancement of augmented reality, visualization and simulation technology. Medical Sciences is one of the potential areas where AR and Mixed reality can be employed, especially in the field of surgery. The need for simulating emergency like situations to prepare surgeons better is one of the many reasons for using these technologies. Different devices such as HoloLens, Google Glass, Apple AR system and Google ARcore are used to produce such solutions. Not only Mixed Reality but Artificial Intelligence and Machine Learning is helping change medical practice in several ways. From diagnosing diseases to improving individual patient care, to provide safety of the highest level. This Review paper reflects how these three modules of Augmented Reality, Artificial Intelligence, and machine Learning be combined together to form a surgical training system. © 2019 IEEE.
