In recent years, artificial intelligence (AI)-based medical and diagnostic assistance programs have been developed all over the world. On the other hand, AI diagnostic support technologies that can be used for adults cannot be applied directly to children or pregnant women, and it is necessary to develop AI technologies suited to the field of pediatric and perinatal medicine that can be applied to children and pregnant women. We, the National Center for Child Health and Development, promotes medical treatment (child health care) and research related to diseases that occur during the life cycle, starting from fertilization and pregnancy, through the fetal, neonatal, infant, school-age, and adolescent stages, and ending in adulthood, when the next generation is being raised. Program (SIP), "Research Project on Advanced Diagnosis and Treatment System by AI (Artificial Intelligence) Hospital," and has been conducting empirical research on medical AI technology from the perspective of pediatric and perinatal care, based on the necessity and challenges of AI technology in the medical field. This presentation will introduce the efforts of the AI Hospital Project at the National Center for Child Health and Development, and outline the present and future of the AI Hospital Project.
