Abstract: Objective By using CiteSpace visualization software, this paper discusses the progress of ultrasound research in acupuncture field in recent 20 years in the form of knowledge graph. Methods A systematic analysis was conducted on the literature publication volume, high-frequency keywords, core research authors, and distribution of important research institutions in this field by using computer retrieval of the CNKI database. Results Since 2003, CNKI has collected a total of 799 relevant literature. In the past decade, the number of related research publications has remained stable, and many key technical teams have been formed in this field. However, there are still few cooperative relationships between institutions, mainly concentrated in affiliated institutions or within the region. It is concluded that the application of ultrasound guidance and ultrasound examination is the hot spot in this field, and the effect mechanism and clinical application research of acupuncture and acupotomy have also been widely concerned. Conclusion Although the application of ultrasound and acupuncture research started late, with the continuous development of technology, research teams are constantly improving.More and more attention has been paid to the application of ultrasonic guidance technology in visual acupotomy methods.In the future, in order to promote exchanges and cooperation between academic teams and institutions, as well as integration between different disciplines and regions, institutions should strengthen communication and expand the depth and breadth of research fields.
