Using the method of literature review, the published literature and data on the clinical application of remote ultrasound at home and abroad are sorted out and analyzed, and the development and application of all aspects of remote ultrasound clinical at home and abroad are preliminarily understood. After finishing, it is found that remote ultrasound has a wide range of clinical applications, which can be used not only in pre-hospital first aid, but also in hospital remote ultrasound consultation and remote monitoring. commonly used in emergency departments, obstetrics, pediatrics, cardiovascular medicine and other departments. Remote ultrasound has synchronous and asynchronous implementation modes. From a single TV monitor or telephone remote consultation, the technology used has gradually developed into a comprehensive transmission of digital, image and voice based on mobile communication devices, wired or wireless networks, etc. The high rate, low delay, large connection, and large storage of cloud computing are the hot spots in recent years, which will make the clinical application of remote ultrasound more efficient.
