The message answer notification of thread and control thread, is sent to client for result.
A kind of control of magnetic resonance imaging and image transmission program are performed the steps of to receive and be swept by what client was sent
After retouching control instruction, it is converted into simulated operation event and operation input is carried out to magnetic resonance genuine software, while screen printing obtains
It executes key frame and carries out Image Matching；The video generation catalogue of magnetic resonance genuine software is monitored, after image is opened in generation one, in real time
It is sent to client.
Compared with prior art, the invention has the following advantages that
1, versatility is high: the present invention uses simulating keyboard and mouse event mode to the method that magnetic resonance controls, it is only necessary to magnetic
A serve end program is disposed at resonance host, is converted to simulated operation event for scan control instruction will to be received
Magnetic resonance imaging control is completed, without calling different vendor's magnetic resonance control interface, any magnetic resonance manufacturer can be adapted to.
2, highly reliable: while carrying out simulated operation event, by additional screen shot and Image Matching Algorithm,
The case where verifying the correctness of this operation, can failing to avoid control process in simulated operation event, it is ensured that entire method
Reliability.
3, image transmission high efficiency: server-side monitors the image of magnetic resonance real-time reconstruction, as long as there is an image reconstruction complete
At being sent to client in real time, all rebuild without waiting for all scanning sequences and complete to be transmitted again, ensure that image passes
Defeated high efficiency.
4, the present invention can most optimally execute scan control and image transmission by the Rational to server-side, occupy
Memory is few, and program stability is high, and it is fast to execute speed.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
As shown in Figure 1, present embodiments providing a kind of control of magnetic resonance imaging and image transmission method.This method by
A serve end program is affixed one's name in magnetic resonance end, for receiving the scan instruction of client, controls magnetic resonance imaging；While listening for magnetic
Resonate image reconstruction, and image is sent to client in real time.The specific implementation steps are as follows for it:
Step s1. client obtains the customized information of magnetic resonance, reads configuration file generation scan control instruction and is sent to
Server-side.Customized information includes scan position, the scanning number of plies and scanning thickness etc..
Step s2. server-side receives scan control instruction, is converted into simulated operation event and carries out to magnetic resonance genuine software
Operation input, while screen printing obtains and executes key frame progress Image Matching.Simulated operation event include simulation mouse it is mobile,
It clicks and double-clicks and simulating keyboard carries out information input.Wherein, committed step includes history scanning sequence, verifying input ginseng
Number, waiting operation response etc..The specific steps that the execution key frame of screen printing carries out Image Matching include:
Step s21. carries out screen interception to the committed step of simulated operation event, obtains and executes key frame.
Step s22. will execute key frame and initial key frame carries out pixel matching, judge whether unanimously, if so, executing
Next simulated operation event；If it is not, then suspending current operation event and information of giving notice.Pixel matching uses existing KMP
Algorithm.
Retrying for certain number can be carried out according to setting value before suspending current operation event, retry can choose from
Successful execution action event starts before any.
Step s3. server-side while listening for magnetic resonance genuine software video generation catalogue, it is real after image is opened in generation one
When be sent to client.After completing single pass control and image transmission, carry out scanning to replicate next time sweeping for the first time
Control operation, while the only customized parameter in amendment step s1 are retouched, the scan control operating time is shortened.
Before executing step s1, need to carry out the preset generation of configuration file.Primary complete people is recorded in client
Work operates the scan operation event of magnetic resonance genuine software, and carries out screen interception acquisition to the committed step in action event
The action event of record and initial key frame are saved as configuration file in client by initial key frame.
As shown in Fig. 2, server-side uses finger daemon (Daemon) design method, monitor on the port of TCP/IP, one
When denier has client request, that is, after receiving connection, and creates a subprocess and go processing client request；Inside work subprocess
There are three thread process different operatings:
Implementing result is sent to transmission thread or control thread for receiving the command request of client by main thread；Prison
The information of video generation is sent to transmission thread by the video generation catalogue for listening magnetic resonance genuine software.
It controls thread and is converted into simulated operation event, while carrying out screen interception for receiving the control command of main thread
And Image Matching, and implementing result is sent to transmission thread.
It transmits thread and the influence of generation is sent to client for receiving the video generation information of main thread；Receive master
The message answer notification of thread and control thread, is sent to client for result.
It is illustrated in figure 3 the workflow of server-side:
After main thread receives the command request of client, the video generation of magnetic resonance genuine software is begun listening for；Client
End sends magnetic resonance imaging control instruction to main thread, and main thread is transmitted to control thread, and control thread passes through simulated operation original
Factory's software carries out magnetic resonance imaging, and by control result by transmitting thread response to client.
After magnetic resonance starts scanning, the image of generation can be listened to by main thread, and main thread leads to the message of video generation
Know and give transmission thread, transmits thread for image and be sent to client.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
