Description
Technical field
It is more particularly to a kind of based on distribution the present invention relates to computer information technology and medical image storage and distribution technology
The ophthalmology image of formula website integrates and dissemination method.
Background technology
With the fast development of Hospital Informatization, Picture Archive and communication system（PACS）At present in state
Interior all types of medical institutions' popularization and applications；The development of simultaneous science and technology, medical level improves constantly and various new medical treatment
Image documentation equipment, which continues to bring out, proposes that access device is more, data are deposited to the Picture Archive in existing hospital and communication system
Chu Geng great, higher requirement, existing medical institutions are generally all each to possess independent a Picture Archive and communication system
System, and the image data between each medical institutions is also relatively independent, only to the open system of oneself, can not realize image
Data are in multiple inter-agency mutually access.
The continuous development of China's Development of China's Urbanization in recent years and public hospital's Extensive Development are constantly lasting, more and more
Medical institutions want to the image data of physically separate each picture archive and communication system to be managed concentratedly.
Realize the tradition side by physically separate each Picture Archive and the centralized management of communication system image data
Method is the new computer hardware equipment of purchase, the network equipment, storage device, erection network and reinstalls one new doctor of implementation
Picture archive and communication system are learned, it is done so that financial cost is high, implementation cycle long serious waste of resources.
If existing hardware resource can be made full use of to set up one by software engineering existing medical image can be deposited
Shelves manage data and the unified system issued concentratedly with communication system, and more hardware device inputs can be avoided to remove hardware from
The cost and difficulty of implementation, unified RELEASE PROBLEM that is more economical, efficiently solving medical image data.
The content of the invention
Goal of the invention：Do not changing the original Picture Archive of each medical institutions and communication system operational mode and operation stream
