Description
Technical field
The present invention relates to remote monitor supervision areas, especially relate to a kind of medical image display side based on cloud
Method, device, equipment and storage medium.
Background technique
DICOM, that is, digital imaging and communications in medicine is the international standard of medical image and relevant information.It defines quality
It is able to satisfy the Medical Image Format that can be used for data exchange of clinical needs.
Traditional DICOM system is generally basede on client control and server-side processes are realized, client control refers to
Client uses the non-HTML such as ActiveX, Java Applet, Flash primary control processing and display image, this technology
The use difficulty and deployment complexity of user are not only increased, but also cannot all be run on the mobile apparatus substantially；And server
End processing then specifies parameter to show reconvert after image processing in webpage at JPG picture according to user on the server, by
It needs constantly to carry out data interaction with server in browser, cause response speed slow and network is relied on too high.
As the appearance and application in 2010 or so HTML5 technologies are come, occur realizing pure Web with HTML5 technology
The DICOM system of version.The core of this kind of scheme is the ability of the operation pixel for the Canvas element that HTML5 is newly provided, and uses
Javascript completes the images operation such as window width and window level adjustment in a browser.But general DICOM HTML5Viewer
It is achieved in that in the browser page of front end and directly downloads DICOM file, then directly decode acquisition figure with Javascript
As data and patient information etc., then window width and window level directly is calculated using Javascript and is shown in Canvas.
Since each inspection has many DICOM files, many systems all can be in webpage in advance one
The some or all of file download of inspection is simultaneously buffered in webpage.And tens M up to a hundred even can easily for the image of each inspection
Reach several G, so it is a very big problem that front end browser, which is directly cached, and in the transmission of mobile terminal, by
It will cause great flow greatly in data volume to occupy, increase the cost of user.

Global extracting method and Promise object in preferably Fetch API, but further include that phase can be achieved in an appearance or the following appearance
Same or identity function effect any other extracting method and optimization object model.
Referring to Fig. 6, in the present embodiment, in the above-mentioned medical image display methods based on cloud, by above-mentioned figure
As file progress designated treatment, and after the step of medical image after above-mentioned designated treatment is shown, further includes:
S6, it shows the check item aim sequence thumbnail, and caches temporarily not shown medical image in user terminal；
S7, when the medical image for receiving user shows request, recall the medical image in above-mentioned display request.
As described in above-mentioned steps S6, the check item aim sequence thumbnail is shown, and cache in user terminal and do not show temporarily
Medical image, it should be noted that when showing the thumbnail of the inspection item, generally only show in the inspection item each
The thumbnail of first medical image of sequence, and show the quantity for the medical image for actually including in each sequence, wherein on
The general name that sequence thumbnail is the thumbnail of first medical image of all sequences in an inspection item is stated, in display breviary
Being that shown medical image is synchronous when scheming and showing normal medical image, in the inspection item carries out pre-cache, wherein pre-
The priority of caching is generally medical image > same sequence medical image > associated sequence medicine that user specifies
Image > remaining sequence medical image.
As described in above-mentioned steps S7, when the medical image for receiving user shows request, above-mentioned display request is recalled
In medical image, above-mentioned steps S6 is being executed or when having executed above-mentioned steps S6, when the medical image for receiving user
When display request, corresponding medical image is called according to the information that above-mentioned display request includes, wherein one in above-mentioned display request
As include the number of display sequence and the number for needing medical image to be shown.
It in the above-mentioned medical image display methods based on cloud, is recalled above-mentioned in the present embodiment referring to Fig. 7
The step of showing the medical image in request, comprising:
S71, judge whether be cached with above-mentioned medical image in the Javascript object of front end；
If uncached in S72, above-mentioned front end Javascript object have above-mentioned medical image, judge that local HTML5 is deposited
Whether above-mentioned medical image is cached in reservoir；
If not finding above-mentioned medical image in S73, local HTML5 memory, acquisition request is sent to cloud server terminal, is obtained
Take above-mentioned medical image.
As described in above-mentioned steps S71, judge whether be cached with above-mentioned medical image in the Javascript object of front end, searches
Above-mentioned front end Javascript object whether there is the doctor of the picture number same label in the display request inputted with user
Learn image.
As described in above-mentioned steps S72, if uncached in above-mentioned front end Javascript object have above-mentioned medical image, sentence
Whether be cached with above-mentioned medical image in disconnected local HTML5 memory, if the judging result of above-mentioned steps S71 be it is no, i.e., it is above-mentioned
It is uncached in the Javascript object of front end to have the above-mentioned of the picture number same label in the display request inputted with user
Medical image then inquires in local HTML5 memory whether be cached with corresponding image；If if the judgement knot of above-mentioned steps S71
Fruit be it is yes, i.e., be cached in above-mentioned front end Javascript object with user input display request in picture number it is identical
The above-mentioned medical image of label, then call the cache image to be shown.
As described in above-mentioned steps S73, if above-mentioned medical image is not found in the HTML5 memory of local, to cloud server terminal
Send acquisition request, obtain above-mentioned medical image, if the judging result of above-mentioned steps S72 be it is no, i.e., in local HTML5 memory
In do not find above-mentioned medical image, then send the acquisition request for obtaining the medical image to cloud server terminal, and re-execute above-mentioned
Step S1-2,；If the judging result of above-mentioned steps S72 be it is yes, i.e., above-mentioned medicine figure is cached in local HTML5 memory
Picture then calls the cache image to be shown.
