The production and case presentation of imaging teaching courseware require the use of "copying photography " technology, or the direct presentation of physical materials such as black and white films and "inspection report forms", which brings great inconvenience to teaching work. With the continuous development of information technology, hospitals have established an Picture Archiving and Communication Systems (PACS) to achieve interconnection between imaging examinations and disease diagnosis and treatment work in various clinical departments. In recent years, the PACS system has been applied to imaging teaching and has achieved significant results. Therefore, this paper mainly discusses the application advantages, specific teaching paths, teaching achievements and development problems of PACS system in imaging technology information teaching, and puts forward countermeasures, in order to provide reference for research and work in related fields.
