Research Progresses in Laparoscopic Augmented Reality Navigation

This paper reviews various LARN (Laparoscopic augmented reality navigation) systems currently used in different clinical fields or reported in literatures, and the LARN systems are classified and described from three different perspectives:the source of the navigation data, the registration method, and the display mode. According to the data sources, from preoperative or intraoperative phases, the LARN systems are divided into LARN based on preoperative data and LARN based on intraoperative data respectively. Focusing on the introduction of registration technology, the research status and characteristics of each typical LARN system are described. Finally, the technical difficulties of LARN in the current clinical application are summarized and the development of the LARN is prospected.
