Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and ExamplesThe present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, andIt is not used in the restriction present invention.
In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Embodiment one：
Fig. 1 shows the flow of the synchronous method of medical RIS system diagnostics report provided in an embodiment of the present invention, in order to justThe part related to the embodiment of the present invention is illustrate only in explanation.
The synchronous method for the medical RIS system diagnostics report that the present embodiment provides comprises the steps：
Step S101, a view is refreshed at interval at regular intervals, when finding to have newly-increased data in RIS systems, readsTake newly-increased patient code, check the store path of numbering and diagnosis report image.
Hospital often does when doing image check for patient and once checks that can all generate unique checks numbers (ApllyID), and each patient has a patient code (Patient ID), for example, can including name, sex, cell-phone number,The information such as date of birth, while in RIS systems, diagnosis report image can all have a store path.Assuming that RIS system in hospitalIn unique check that numbering is 7, it is necessary to a byte；Name up to 4 Chinese characters are, it is necessary to 8 bytes, cell-phone number 13Position is, it is necessary to which 2 bytes, probably have 16 plus the other informations such as sex and birthdate, patient code's information in additionByte, patient code's information of 60 patients are about 1K bytes, and the time caused by this patient code's information is transmitted in networkDelay is negligible.
Step S102, diagnosis report image is read according to the store path of the diagnosis report image, and stores and arrive fileIn folder.
Front server, according to store path, reads figure after patient code has been read, check numbering from RIS systemsAs file, and store into the local file by the name of store path name.
Step S103, whether there are newly-increased diagnosis report image, i.e. delta file every preset time run-down；
If delta file step S104, be present, the port completed is combined by using sockets sockets increment is literaryPart and corresponding patient code, check that numbering is synchronized to cloud server.
In order to reduce the operating pressure of front server device, front server, only need to be every without real time scan local fileEvery preset time run-down, such as 1 minute.And in step S101, due to patient code, check numbering and diagnosisReport that the data volume of the store path of image is smaller, a view can be refreshed with every 1 second, in time go out diagnosis report image readingIt is stored in local.
After preset time, when finding there is newly-increased diagnosis report image, using sockets sockets port, it will increaseAmount file and corresponding patient code, check that numbering is synchronized to cloud server.
The Cloud Server can receive the data that each hospital's front server uploads as data storage center.OftenIndividual hospital all sets a front server, and so each front server obtains the diagnosis in corresponding RIS system in hospital respectivelyView data is reported, is then uniformly uploaded to cloud server.When patient or hospital need to check diagnosis report, awardedQuan Hou, searched from each front-end server and obtain required diagnosis report image.
This method by the diagnosis report view data in medical RIS systems and for patient code, check that numbering is sameStep is to front-end server, and then Timing Synchronization to cloud server, realizes RIS system diagnostics report view data and patient and itsHis medical institutions share.

As a kind of specific processing mode, as shown in figure 3, the step S203 is specifically included：
S301, diagnosis report image is ranked up according to sequencing.
Diagnosis report report typically has multiple, it is assumed that there is m width images.
S302, for every piece image, generate w-1 point at random in width, h-1 generated at random in short transversePoint, each image split into w × h grid block of pixels.
In each image, the grid pixel block size split into is random, and unrelated, each image has w × h pixelBlock.
S303, random one block of pixels of taking-up carries out first round selection from each width image in order, then from each width figureBlock of pixels progress the second wheel selection, all pixels so after w × h wheels are chosen are taken out as random in remaining block of pixelsBlock has been chosen, obtain a memory block matrix B=Wherein m is amount of images,TzXijWhen being chosen for the i-th wheel, the X that is randomly selected from z width imagesijIndividual block of pixels, here Xij∈[1,w×h]。
Reference picture 5, from piece image to m width images, a block of pixels is randomly selected successively, is then proceeded to eachContinue to randomly select in the remaining block of pixels of image, until the block of pixels selection of all images finishes.Here m width image point is markedWei not T1、T2、…、Tm, in the first round is chosen, image T1X11Individual block of pixels is selected, image T2X12Individual block of pixelsIt is selected, image TmX1mIndividual block of pixels is selected, and selected pixels block is respectively labeled as T1X11、T2X12、、TmX1m.According toIt is secondary to analogize, then, when the i-th wheel is chosen, the X that is randomly selected from z width imagesijIndividual block of pixels, can mark and bezXij.InstituteAfter the block of pixels for having image has been chosen, obtain a memory block matrix B=ShouldMatrix is the data for reconfiguring to obtain after image is split.
S304, it is that each block of pixels stored in block matrix is multiplied by a luminance factor, obtains deformation matrixWhereinWherein functionRepresent block of pixels F average brightness value, brightness value on the basis of D, the delta file after the processing is the changeShape Matrix C.As j=m,As j=1,
Each block of pixels is multiplied by order to which further the data in block of pixels are encrypted, in this step a brightness becauseSon, block of pixels TzXijLuminance factor be αij, chosen for the i-th wheel, image TzIn the X that randomly selectsijIndividual block of pixels it is brightSpend the factor and other all images when the block of pixels selected by front-wheel is related, and also before and after being averaged selected by two sub-picturesBrightness is related, in expression formula, brightness value on the basis of D, for definite value known to acquiescence.
Key corresponding to S305, generation Current Diagnostic report image, the key include w and h, in addition to cipher key matrix
Image after splitting combined treatment needs that by key decryption reduction could be realized at front server end.ThisIn key selected w and h when including splitting in figure, also include cipher key matrix certainlyHere during cipher key matrix is often wheel selects, the numbering X of the specifically chosen block of pixels of each imageij.Of course for fast and easy meterCalculate, the key also includes luminance factor matrix
In above-mentioned cipher key matrix E, cipher key matrix can further be deformed so that cipher key matrix is safer.ThisIn 2 × 2 region segmentations are proceeded by from the upper left corner to the cipher key matrix that includes, there are 4 elements in each region, in each regionElement according to a position rotationally clockwise, if the columns of cipher key matrix is odd number, do not handle last column element,If the line number of cipher key matrix is odd number, last column element is not handled.
Step S204, whether there are newly-increased diagnosis report image, i.e. delta file every preset time run-down.
If delta file step S205, be present, the port completed is combined by using sockets sockets by after processingDelta file and key and corresponding patient code, check that numbering is synchronized to cloud server.
The present embodiment is with the difference of embodiment one, and in the present embodiment, front-end server is preserving diagnosis report figure, it is necessary to carry out fractionation combined treatment, i.e. encryption to diagnosis report image as after, and obtain key.Then again every defaultThe diagnosis report image whether time sweep increases newly, i.e. delta file, the view data after the delta file is untreated.IfDelta file be present, using sockets sockets port, by delta file and corresponding patient code, check that numbering is synchronousTo cloud server.So diagnosis report image, in the case where not obtaining key, can not reduce patient by processingDiagnosis report image, the privacy of patient is ensure that, it is aobvious to the processing of diagnosis report image encryption especially for some Very Important PersonObtain particularly important.
