The invention discloses a medical image transmission method based on a 5G network. The medical image transmission method specifically comprises the following steps: 1, hardware architecture; 2, image acquisition and packaging; 3, deblocking and reducing; 4, fault-tolerant processing. The invention relates to the technical field of medical communication. According to the medical image transmission method based on the 5G network, a 5G network hardware framework system is constructed, information transmission is performed by using the characteristics of low time delay and high rate of the 5G network, and a client message system is formed by cooperating with a client, a slice information unit, a state information monitoring unit, a fault-tolerant information unit and an identification unit. A server, a transmission data recording module, a slice image information module, a data information module and a data integration module are utilized to form a server-side heat preservation system, and after packaging-unpackaging is conducted, it is guaranteed that the transmission environment is high in speed and stable, and meanwhile medical images with the large data size can be completely and rapidly transmitted and stored to a remote safety server.
