Description
Technical field
The present invention relates to a kind of transmission of medical image, the method for especially a kind of cross-platform multi-screen interactive of medical image.
Background technology
With the development of information technology, medical technology and Internet technology are constantly progressive, and the diversification of application terminal is deposited
In the usage scenario of various ways telecommuting.But in the remote medical consultation with specialists for carrying out medical image, Cases Discussion, differently
Domain passes through different device ends（Such as Pad, mobile phone, the ends PC）It is explained with participant's operations various to the carry out of case image
State the discovery of oneself.Current solution is realized by the Screen sharing function of video conferencing system, and a side is obtaining
After control, various operations are carried out to image, each participant side is transferred in a manner of video flowing.There are many for this mode
Defect：The terminal display resolution ratio that participant uses first is different, to ensure display effect, can only unify to arrive same resolution
Rate, to avoid because of mass loss caused by image stretch；Secondly the big resolution for mostly using 720P of video steaming transfer at present
Rate seldom uses 1080P.Even the resolution ratio of 1080P also cannot be satisfied the resolution requirement of medical image, and it is even more impossible to use specially
The greyscale display of industry；In addition, the transmitted data amount of video flowing on the internet is big, delay is more, causes operation not smooth, uses
Family experience effect is poor.
Invention content
It is cross-platform that a kind of medical image is provided the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art
The method of multi-screen interactive, simultaneous display, the processing operation realized remote medical consultation with specialists, diagnose traditional Chinese medicine image.
To achieve the goals above, the method for the cross-platform multi-screen interactive of a kind of medical image designed by the present invention, including
Following steps：
1）Establish WebSocket server-side WEB api interfaces, realization includes creating meeting room, into meeting room, acquisition room
Between list, obtain room user list, demonstration right exchange, new information receive etc.；
2）Client needs three presider, participant and keeper entrances；
3）Presider creates User ID using client, passes through this User ID and creates meeting room, server-side distributes room ID, writes from memory
Recognize and the User ID client is notified to possess presider's permission；
4）Participant creates User ID using client, enters the room chosen by this User ID, server-side notifies the user
ID clients possess participant's permission；
5）Keeper creates User ID using client, enters the room chosen by this User ID, server-side notifies the user
ID clients possess keeper's permission；
6）Presider is responsible for that the operational motion of all images of oneself client is defined as operation seat by io.js case mechanisms
Mark, and collect, handle, being integrated into message queue and being sent to server-side in real time；
7）Server-side verification, the client for receiving, being sent to participant and keeper after processing message queue again；
8）Participant is responsible for the message queue received, processing server-side is sent, and all operations are disappeared by io.js case mechanisms
Breath is pushed to the client of oneself, ensures that client can operate coordinate and relevant information, keeper with correct order restoring
It is responsible for record conference content；
9）Participant needs it is necessary to send the application as presider to server-side when demonstration, and server-side can send this application
To the client of current presider, presider demonstrates right swap fault if not receiving, if receiving server-side is notified that Shen
The client of participant please possesses presider's permission；Corresponding original presider is converted to participant, after demonstration right exchanges,
New presider continues demonstration operation on the basis of original imaging operations；
10）When demonstration terminates, presider, which sends, closes room request, and server-side can receive room ID and User ID resource
It returns, meeting room is closed.
The window width and window level adjustment of image in the message processing procedure of partial image operation：
Presider is by the current window width and window level data of the good action type of room ID, User ID, predefined and operated image
It is stored in message, message inbound message queue is sent to server-side, is sent to participant after server-side processing, participant is according to thing
The action type first defined executes corresponding operating method and is passed to window width and window level data to browsing image device.
Operation in the message processing procedure of partial image operation to DOM node：
Client is obtained in advance there are the DOM node of event and classification storage, when DOM event generates presider by room ID,
In the DOM event data deposit message that the good action type of User ID, predefined, DOM event type and needs are sent, message
Inbound message queue is sent to server-side, is sent to participant after server-side processing, participant is according to the good operation of predefined
Type and event type execute the event of corresponding DOM node and incoming DOM event data.
Browsing image device is that a Dicom medical image based on browser shows that program will be cured using Html5 technologies
Learn visual renderings in a browser, and provide it is a series of such as：Adjust the operation of the auxiliary diagnosis such as window, scaling, movement.Html5 technology energy
All kinds of operating terminal systems are enough adapted to, browsing, display and related application operation can be realized well, to realize cross-platform
Operation.In addition, the browser program can be by these Operation Definitions at an operation object, positioning operation coordinate, and will be a series of
It operates continuously coordinate and forms operation queue, by sending a series of operation queue, client receives and parses through operation queue, real
The interaction of the cross-platform multi-screen of existing medical image.Client mentioned below refers both to the browsing image device.
WebSocket agreements are a kind of new procotols based on TCP.It realizes browser and server full duplex
(full-duplex) communication-- allows server actively to send information to client.
Io.js is a platform established when being run based on Chrome JavaScript, for easily building response
Speed is fast, is easy to the network application of extension.Io.js use event-driven, Non-Blocking I/O models and be able to light weight and efficiently,
It is highly suitable for the real-time application of operation data intensity on distributed apparatus.The case mechanism of io.js is real based on V8 engines
Existing event-driven IO, it is that work is added in event queue, and then there are one one events of individual thread operation to follow
Ring extracts this work.Event loop captures uppermost entry in event queue, executes it, then captures next
Entry, until event loop terminates.
Based on WebSocket agreements, all diagnostic operations for image are obtained by io.js case mechanisms, then with
The form of message queue sends and receives to realize that diagnostic imaging operation is synchronous on different platform client browser, Ke Yiyou
Effect solves the problems, such as present on.Whole process is all that the operational motion of client is synchronizing, the data volume pole of transmission
Few, display operation is smooth；Participant can use the profession and regular display of arbitrary resolution, therefore will not lead to image
Distortion；Support demonstration is weighed to exchange and can retain whole operation path simultaneously, participant midway participates in, and can also be quickly obtained and master
The consistent dispaly state of prosecutor.
A kind of method for the cross-platform multi-screen interactive of medical image that the present invention obtains, display operation are smooth, and participant can be with
Using the profession and regular display of arbitrary resolution, therefore image distortion will not be led to；Demonstration power is supported to exchange simultaneously simultaneously
Whole operation path can be retained, participant midway participates in, and can also be quickly obtained the dispaly state consistent with presider.
Specific implementation mode
With reference to embodiment, the present invention is further described.
