Abstract: Whether artificial intelligent (AI) can gradually replace human beings to diagnose and treat diseases is currently a worldwide hot topic. The mass storage, fast computation, tireless learning, and endless upgrading make AI possible to replace and surpass human beings in diagnosis first. With the development of computer image analysis, industrial automation and artificial feedback control technology, therapeutic AI robot system has become reality. This kind of therapeutic system is gradually applied to the microsurgery field which needs great precision and stability. AI robots were also applied in therapeutic interventional radiology as for the safety of human interventionists. The first case of a human intracranial aneurysm treated by an AI robot was reported by the Western Toronto Hospital of Canada in November, 2019. This paper introduces the application of AI in cerebrovascular diagnosis, especially the application of interventional surgery robot in neuro-interventional diagnosis and treatment, and discusses the application prospect of AI.
