Compared with foreign manufacturers, PACS has strong image processing ability, and most of them include three-dimensional post-processing function. Domestic manufacturers are short board and RIS flow systems. Compared with foreign manufacturers, domestic manufacturers have obvious advantages and strong localization and personalization capabilities. Foreign manufacturers basically do not provide personalized service. It is suggested that the manufacturer should be selected according to the hospital level and actual demand. Foreign mainstream manufacturers: Siemens, GE, Ruike; Domestic mainstream manufacturers: Weining, New Network, Donghua, Blue Network, England and Feida. Personally, it is not recommended to choose PACS produced by other manufacturers. After all, there is specialization in the industry, and the business focus is not here, because employees in their own industry do not recommend specific manufacturers.
