[0002] Digital pathology sections are a technology that converts traditional glass pathology sections into digital images through a high-resolution scanner. Digital pathology sections are usually saved in files or folders of different formats. Digital pathology sections are generally uploaded to the web front end for medical staff to view. However, since the format of digital pathology sections is generally large and the upload time is long, there may be a possibility of accidentally closing the web page during the upload process, resulting in an inability to continue uploading, or the upload may fail due to a timeout in a weak network state, thereby affecting the efficiency of remote diagnosis and wasting a lot of time and network resources.

[0003] In addition, when uploading digital pathology sections to the web front end, it is impossible to preview the digital pathology sections during the uploading process, so there is a possibility that the digital pathology sections of other patients may be uploaded by mistake, resulting in medical accidents.

[0032] Embodiment 1

[0033] The embodiment of the present application provides a method for uploading digital pathology slices based on a web front end, by slicing the data stream and uploading it, and setting an index for each data segment, even if the upload is interrupted by a weak network, the breakpoint can be accurately resumed. Specifically, refer to Figure 1 , the method comprising:

[0034] The data unit storing the digital pathology slices is constructed as a data object and saved in a web front-end database, and at least one data stream storing the digital pathology slices is obtained based on the data object;

[0035] A unique upload identifier is set for each data stream, and the data streams are uploaded one by one in a predetermined order based on a slicing upload method. The slicing upload method is: cutting the data stream into multiple data segments, and setting an index value for each data segment, and uploading the data segments in the order of the index value from small to large;

[0036] During the slice upload process, the index value of the latest uploaded data segment at the time node and the corresponding upload identifier are recorded in real time as the resume position. When the upload is interrupted and needs to be resumed, the data segment with the index value + 1 in the resume position is used to resume the upload.

[0037] The upload results of all data streams are merged to complete the upload of digital pathology sections.

[0038] That is to say, through the digital pathology section uploading method of this scheme, if the upload is stopped due to the accidental closure of the browser or a weak network, there is no need to restart the upload when the browser is opened again for uploading. The upload can be resumed based on the latest uploaded data segment index value and the corresponding upload identifier at the real-time recording time node.

[0039] For example, when the data segment with upload identifier A and index a in the data stream is uploaded, the resume position Aa is saved in the web front-end database. At this time, if the user accidentally closes the browser, the upload can be resumed when the browser is opened again, that is, uploading from the data segment with upload identifier A and index a+1.

[0040] In some specific embodiments, the data unit may be a file or a folder. When the data unit is a file, it indicates that the digital pathology slice is saved in a single file. When the data unit is a folder, it indicates that the digital pathology slice is divided into multiple files and saved in the folder.

[0041] In this solution, a data object is constructed based on the handle of the data unit and saved in the web front-end database.

[0042] Exemplarily, the Browser-FS-Access tool is used to select a file storing digital pathology slides or a folder storing digital pathology slides, and then a data object is constructed based on the handle of the file or folder together with related information and saved in the web front-end database.

[0043] Furthermore, the web front-end database is an IndexDB database.

[0044] In some specific embodiments, the file names in the files storing digital pathology slices are all numerically sorted. For example, the slices are composed of file header information PicHead + patient information PersonInfo + additional information ExtraInfo + macroscopic image information and its image Jpeg data + thumbnail information and its image Jpeg data + each level information and its tile data. Therefore, the files of each level are named with a unified prefix + level number + file format, and files with other information are named with a unified prefix + specific English + file format, which is used as the basis for the back-end slices to be parsed into images. The level numbers in the hierarchical files are the numerical sorting.

[0045] In this solution, when the data unit is a folder, the data object consists of the folder name, a keyword for determining whether the data unit is a folder, the random number of the folder, and the file name with the last number in the folder sorted.

[0046] That is to say, when the data unit is a folder, the data stream obtained by this solution is the files in the folder. Through the constructed data object, the files in the user file system can be accessed more directly in the client, reducing network latency and bandwidth consumption, and improving the response speed and performance of the application.

[0047] For example, when the data unit is a folder, the data object consists of directoryName and uuidDirectoryName, which is unique to the folder. DirectoryName is the folder name. uuidDirectoryName includes SliceFolderDir (a keyword for determining that the data is a folder), uuid (a random number for the folder), and the last file name is the number in the folder. For example, a folder storing digital pathology slides is Figure 2 As shown, the file name last in the numerical sorting is 20240123_142654_0_Layer7.dcm, and the data object is \'sdpcX20":\"sliceFolderDir / b134a3d6-dcf-404d-9c50-5658a308384 / 20240123_142654_0_Layer7.dcm. den\"l, that is, when obtaining the data stream based on the data object, if the data stream with the file name 20240123_142654_0_Layer7.dcm is obtained, it means that the data stream in this folder has been obtained.

[0048] In this solution, when the data unit is a file, the data object consists of the name of the folder to which the file belongs, a keyword for determining that the data unit is a file, a random number of the file, and the file name.

[0049] Compared to the data unit being a folder, a file is a separate part, so when only one data stream is obtained, the data object does not need to contain the file name that is sorted numerically at the end, but can be replaced with the file name itself.

[0050] In this solution, the data stream of each file in the data unit is obtained through the handle.getFile() function.

[0051] In this solution, any data stream can be accurately located through a unique upload identifier, so when resuming the upload, the resuming position can be relocated based on the upload identifier, without having to start uploading from the beginning, saving a lot of uploading time. Specifically, the upload identifier is represented by UploadId.

[0052] In some specific embodiments, the predetermined order is the digital ordering of files corresponding to the data stream. Since the data stream is the file content in the acquired data unit, and in the storage of data pathology slices, each file will have a digital ordering. For example, the hierarchical files are named with a unified prefix + a hierarchical number + a file format, and the hierarchical number here is the digital ordering of the files.

[0053] In the step of "cutting the data stream into multiple data fragments", each data stream is cut according to a set size to obtain multiple data fragments of the same size. If the size of the remaining data is smaller than the set size, it is regarded as one data fragment.

[0054] Furthermore, in this solution, the upload identifier of the data stream and the index value of each data segment are stored in the web front-end database to ensure that the corresponding data segment can be accurately found according to the resume position when resuming the data.

[0055] Furthermore, after “cutting the data stream into multiple data segments”, each data segment is verified to ensure that data is not lost.

[0056] Exemplarily, this solution will cut the data stream with a set size of 10mb. When the size of the data stream is 95mb, the data stream will be cut into 10 data fragments, and the size of the last data fragment is 5mb. After the cutting is completed, each data fragment will be matched with the verification code uploaded by the front end to complete the verification of each data fragment. The index value of the data fragment starts from 0.

[0057] In this solution, the upload progress of each data stream is recorded and saved in the web front-end database, where upload progress = size of each data segment * (current index value index+1) / data stream size.

[0058] In some specific embodiments, an upload status is set for each data stream in a web front-end database, the upload status of a data stream that has been cut into multiple data segments is set to ready to upload, the upload status of a data stream being uploaded is set to uploading, and the upload status of a data stream whose upload has been completed is set to upload completed.

[0059] During the upload process, the user can issue instructions at any time to control the upload process. For example, when the user chooses to pause during the upload process, the upload request will be canceled, and the upload status of the data stream being uploaded will be set to paused. When the user chooses to resume the upload after pausing, the upload will be resumed based on the method mentioned above, and the upload status of the data stream with the paused upload status will be set to uploading.

[0060] For example, a data stream is cut into 50 10 MB data segments. During the slice upload process, the data segment uploaded at the time node is recorded in real time as the 11th. Then, when resuming the upload, jump to the address of the 12th data segment (10*1024*1024*11=115343360B, 10 represents the data block size, the subsequent two 1024s represent converting 10MB into bytes, 11 represents the current file block position, and 115343360B represents the position in the file) for resuming the upload.

[0061] When the user chooses to retransmit during the upload process, a unique upload identifier is set for each data stream, and the data streams are uploaded one by one in a predetermined order based on the slice upload method.

[0062] That is to say, if the user chooses to retransmit during the upload process, a unique upload identifier will be set for each data stream, so the data stream will be cut into multiple data segments again.

[0063] When the user chooses to cancel the upload during the upload process, all relevant information will be deleted according to the upload identifier of each data stream.

[0064] During the upload process, the window life cycle is monitored. When the program executes window.onbeforeunload, it is considered that the user refreshes the page. When the user refreshes the page, it is determined that the upload is interrupted and resumed.

[0065] In this solution, when the user refreshes the page, the upload status of the data stream being uploaded is set to paused, and after the upload is resumed, the upload status of the data stream with the paused upload status is set to uploading.

[0066] In some specific embodiments, when the data unit is a file, the digital pathology slide upload flow chart is as follows: Figure 3 As shown, since the data unit is a file, the uploading of the entire digital pathology section is completed when all data segments are uploaded.

[0067] In some specific embodiments, when the data unit is a folder, the digital pathology slide upload flow chart is as follows: Figure 4 As shown, when the digital sorting in the folder is completed and the last file is uploaded, all the uploaded results are merged to complete the upload of the digital pathology slides.

[0068] In some specific embodiments, since the digital pathology slice protocols of different manufacturers are inconsistent or not open, and the web front end cannot directly call the C / C++ or C# parsing class library to parse the digital pathology slice, the content of the digital pathology slice cannot be previewed during the upload process. In this solution, a preview plug-in is constructed, and the preview plug-in obtains the path address of the digital pathology slice and sends it to the back end. The back end parses the pathology slice according to the path address of the digital pathology slice to obtain preview information. After the web front end is linked to the back end, the preview information is previewed through the preview plug-in.

[0069] Specifically, since there are many formats of slices, such as .sdpc, .svs, dcm, .dcmz, .tiff, etc., and the web front-end can only preview digital pathology slices in sdpc format, in order to ensure that all formats of pathology slices can be previewed, this solution builds a preview plug-in and parses the content of the digital pathology slices through the back-end. Then, by linking the web front-end with the back-end, the web front-end can preview all formats of digital pathology slices.

[0070] Specifically, the pathological slice information is the structural data and metadata of the pathological slice, such as tile size, level information, etc., and the preview position information is the specific position and level to be previewed, including the current preview field of view position, zoom ratio and size.

[0071] Specifically, due to the inherent performance limitations of the web front-end, intensive image processing cannot be performed through web programs, so this solution uses the back-end to call local resources such as memory, CPU, and graphics card to return tile data to the front-end for preview.

[0072] In some specific embodiments, if the web front end requests preview from the back end multiple times, higher resource requirements will be placed on the back end, and the cost will also increase, so the back end caches the original data of the digital pathology slices on a local disk.

[0073] Furthermore, the original data in the local disk adopts the LFU or LRU elimination strategy to eliminate the common unused data in the past, saving disk resources. At the same time, for the commonly used data, the local background service is directly hit in the future, without requesting network resources again, saving bandwidth, CPU, memory resources, etc.

[0074] Embodiment 2

[0075] A backend uploading method for digital pathological sections based on a web front end, comprising:

[0076] When the web front end is closed and not reopened, the back end obtains the upload permission and the address and interface of the target server, and uploads the data stream using the slice upload method described in Example 1;

[0077] The backend transmits the upload progress to the web frontend in real time via websocket.

[0078] Furthermore, when uploading data streams, the web front-end will send a file resource management list to the local background service, that is, the back-end, and transfer the upload permission to the background service by encrypting the address and interface of the target server. The background service will also use the file segmentation and address jumping method of the first method to read and upload the file and record the data in the local MySQL database. At the same time, the upload progress will be transmitted back to the web front-end logged in to the account in real time through websocket to ensure that the data will not be transmitted back to other accounts. The target server is the storage location of the uploaded digital pathology sections.

[0079] Specifically, under the premise of complying with the protocol, this solution is fully compatible with different software platform automatic backgrounds, such as: internal platform reading meetings, remote diagnosis platforms, etc. or third-party platforms.

[0080] Specifically, since the backend does not know to which storage service of the remote server the web frontend will transfer the slice data when the upload starts, and how the local backend service upload notifies the remote backend service of the web page of the upload status information, this solution passes the address and interface of the target server to the backend in json text encryption. The backend obtains the data and parses the upload interface, and the strategy automatically creates a call service for automatic notification.

[0081] Specifically, when the upload is completed, the link between the backend and the target server is automatically destroyed.

[0082] In some other embodiments, the link between the backend and the target server is set to auto-start mode to ensure that the upload can be automatically performed even when the computer is restarted, thereby adding a layer of guaranteed service.

[0087] The resuming module is used to record the latest uploaded data segment index value and the corresponding upload identifier as the resuming position in real time during the slice uploading process. When the upload is interrupted and needs to be resumed, the data segment with the index value + 1 in the resuming position is started to be resumed;

[0088] The merging module is used to merge the upload results of all data streams to complete the upload of digital pathology sections.

At least one data stream storing the digital pathology slices is obtained based on the data object, wherein when the data unit is a folder, the data object consists of a folder name, a keyword for judging that the data unit is a folder, a random number of the folder, and a file name whose digital sequence is the last, and the obtained data stream is a file in the folder; A unique upload identifier is set for each data stream, and the data streams are uploaded one by one in a predetermined order based on a slicing upload method. The slicing upload method is: the data stream is cut into multiple data segments, and an index value is set for each data segment, and the data segments are uploaded in ascending order of the index value. When the user chooses to retransmit during the upload process, a unique upload identifier is set for each data stream again, and the data streams are uploaded one by one in a predetermined order based on the slicing upload method. When the user chooses to cancel the upload during the upload process, all relevant information is deleted according to the upload identifier of each data stream. When the user refreshes the page, it is determined that the upload is interrupted and the upload is resumed; During the slice upload process, the index value of the latest uploaded data segment at the time node and the corresponding upload identifier are recorded in real time as the resume position. When the upload is interrupted and needs to be resumed, the data segment with the index value + 1 in the resume position is used to resume the upload. A preview plug-in is constructed. The preview plug-in obtains the path address of the digital pathology slice and sends it to the back end. The back end parses the pathology slice according to the path address of the digital pathology slice to obtain preview information. After the web front end is linked to the back end, the preview information is previewed through the preview plug-in, wherein the preview information is the specific position and level to be previewed, including the current preview field position, zoom factor and size; The upload results of all data streams are merged to complete the upload of digital pathology sections. When the web front end is closed and not reopened, the back end obtains the upload permission and uploads the data stream. The back end transmits the upload progress to the web front end in real time through websocket. When uploading the data stream, the web front end sends a file resource management list to the back end, and transfers the upload permission to the back end in an encrypted manner by transferring the address and interface of the target server. The back end reads and uploads the file and records the data in the local MySQL database. At the same time, the upload progress is transmitted back to the web front end logged in to the same account through websocket in real time to ensure that the data will not be transmitted back to other accounts. The target server is the storage location after the digital pathology sections are uploaded.

A method for uploading digital pathological sections based on a web front end according to claim 1, characterized in that: When the data unit is a file, the data object consists of the name of the folder to which the file belongs, a keyword for determining that the data unit is a file, a random number of the file, and the file name.

3. A method for uploading digital pathological sections based on a web front end according to claim 1, characterized in that: In the step of "cutting the data stream into multiple data fragments and setting an index value for each data fragment", each data stream is cut according to the set size to obtain multiple data fragments of the same size. If the remaining data size is smaller than the set size, it is regarded as one data fragment.

4. A digital pathology slice uploading device based on a web front end, characterized in that: include: A construction module, used to construct a data unit storing digital pathology slices into a data object and save it to a web front-end database, wherein the data unit can be a file or a folder. When the data unit is a file, it means that the digital pathology slices are saved in a single file. When the data unit is a folder, it means that the digital pathology slices are divided into multiple files and saved in the folder. A file storing digital pathology slices or a folder storing digital pathology slices is selected, and then a data object is constructed based on the handle of the file or folder together with relevant information and saved in the web front-end database. At least one data stream storing digital pathology slices is obtained based on the data object. When the data unit is a folder, the data object consists of a folder name, a keyword for judging that the data unit is a folder, a random number of the folder, and a file name whose numbers are sorted in the folder, and the obtained data stream is a file in the folder; An upload module, used to set a unique upload identifier for each data stream, and upload the data streams one by one in a predetermined order based on a slicing upload method, wherein the slicing upload method is: cutting the data stream into multiple data segments, and setting an index value for each data segment, and uploading the data segments in ascending order of the index value; when the user chooses to retransmit during the upload process, a unique upload identifier is re-set for each data stream, and the data streams are uploaded one by one in a predetermined order based on the slicing upload method; when the user chooses to cancel the upload during the upload process, all relevant information is deleted according to the upload identifier of each data stream, and when the user refreshes the page, it is determined that the upload is interrupted and the upload is resumed; A resume module is used to record in real time the index value of the latest uploaded data segment and the corresponding upload identifier as the resume position during the slice upload process. When the upload is interrupted and needs to be resumed, the resumed transmission starts with the data segment with the index value + 1 in the resume position. A preview plug-in is constructed.
