Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The image storage method provided by the application can be applied to the application environment shown in fig. 1. The application environment includes a terminal 102 and a server 104; wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, an image storage method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
The storage request comprises first object data of the image to be stored.
The terminal receives a storage instruction input by a user and determines the image to be stored according to the storage instruction. And then, the terminal generates first object data and a storage request according to the image to be stored. Then, the terminal transmits a storage request to the server. Correspondingly, the server receives a storage request sent by the terminal and analyzes the first object data of the object to be stored from the storage request.
The image to be stored may be a medical image, such as a CT (Computed Tomography) image, an MR (Magnetic Resonance) image, an ultrasound image, and the like.
In step 202, a metadata record corresponding to the first object data is searched in a metadata table stored in a preset storage engine. Namely, the metadata record corresponding to the first object data is searched in a metadata table, and the metadata table is stored in a preset storage engine.
The server is preset with a storage engine, which may be but not limited to kudu, elasticsearch, hbase, and all of these storage engines have a real-time query function. The storage engine is provided with a metadata table, and the metadata table is used for storing metadata records. Wherein the metadata is data describing the object data. A metadata record is a record generated from metadata.
In an alternative embodiment, the metadata record includes at least one of a unique identifier of the object data, a storage location of the object data, a length of the object data, a timestamp of the object data, a type of the image, a user identifier corresponding to the image, a unique identifier of the image, an examination identifier corresponding to the image, and an identifier of an image sequence corresponding to the image. Wherein the image type may indicate whether the image is a CT image, an MR image, or an ultrasound image. The examination mark corresponding to the image can indicate a series of examinations for a certain disease. The metadata records are shown in the following table:
after the server acquires the first object data, the server searches the metadata table for the metadata record corresponding to the first object data. If the server finds a metadata record corresponding to the first object data in the metadata table indicating that the first object data is already stored, the first object data is no longer stored. The server may feed back to the terminal that the first object data is stored. If the server does not find the metadata record corresponding to the first object data in the metadata table, it indicates that the first object data is not stored, step 203 is executed.
In step 203, if the metadata record corresponding to the first object data is not found in the metadata table, the first object data is stored.
The storage request also includes a storage location. And if the server does not find the metadata record corresponding to the first object data in the metadata table, storing the first object data according to the storage position carried in the storage request.
In practical applications, a plurality of object storage service nodes may be provided, and the server receiving the storage request is one of the plurality of object storage server nodes. And when the first object data is stored, storing the first object data to one of the object storage service nodes according to the storage position carried in the storage request.
At step 204, a first metadata record describing the first object data is generated and inserted into the metadata table.
The server, when storing the first object data, also generates a first metadata record as shown in the above table, the metadata in the first metadata record being used to describe the first object data. After the first metadata record is generated, the first metadata record is inserted into a metadata table.
In the image storage method, a server receives a storage request, wherein the storage request comprises first object data of an image to be stored; searching a metadata record corresponding to the first object data in a preset metadata table stored by a storage engine; if the metadata record corresponding to the first object data is not found in the metadata table, storing the first object data; a first metadata record describing the first object data is generated and inserted into the metadata table. In the embodiment of the disclosure, the metadata describing the object data is stored in the storage engine with real-time query, and when the image is retrieved subsequently, the object data can be searched in real time according to the metadata, so that the retrieval speed can be improved. Furthermore, the metadata record corresponds to the object data, and maintainability is high.
In an embodiment, as shown in fig. 3, the step of searching for the metadata record corresponding to the first object data in the metadata table stored in the preset storage engine may include:
In practical application, after the terminal sends the first object data of the image to be stored to the server, the server needs to analyze the first object data first to obtain the first image information of the image to be stored.
For example, the server analyzes the first object data to obtain an image type of the image to be stored, an image sequence identifier corresponding to the image to be stored, a patient number and a patient name corresponding to the image to be stored, a unique identifier of the image to be stored, an examination identifier corresponding to the image to be stored, and the like.
After the server parses the first image information, the metadata table may be searched according to the first image information. If the metadata record corresponding to the first image information is found, indicating that the first object data is stored; and if the metadata record corresponding to the first image information is not found, representing that the first object data is not stored.
In one embodiment, since the server parses the first object data to obtain the first image information of the image to be stored, when generating the first metadata record describing the first object data, the first metadata record may be generated according to the object information of the first object data and the first image information. The object information may include a unique identifier of the object data, a storage location of the object data, a length of the object data, and a timestamp of the object data, and the first image information may include at least one of an image type, a user identifier corresponding to an image, an image unique identifier, an examination identifier corresponding to an image, and an image sequence identifier corresponding to an image.
In one embodiment, the metadata table may be further searched according to the first image information and the related information of the first object data. The embodiments of the present disclosure do not limit this.
Analyzing the first object data to obtain first image information of an image to be stored; the metadata table is searched for a metadata record corresponding to the first image information, and after the first object data is stored, a first metadata record describing the first object data is generated according to the object information of the first object data and the first image information. In the embodiment of the disclosure, because the image information and the object information are stored in the metadata table together, the object data of the medical image can be searched in real time according to the image information; in addition, index information and image information do not need to be stored, an index database and an image information database do not need to be established, and the storage, management and maintenance cost of mass image data can be effectively reduced.
In one embodiment, as shown in fig. 4, an image storage method is provided, which may include the following steps:
The storage request comprises first object data of the image to be stored.
In step 403, the metadata table is searched for a metadata record corresponding to the first video information.
And if the server does not find the metadata record corresponding to the first object data in the metadata table, which indicates that the first object data is not stored, compressing the first object data based on a compression algorithm of the dicom file to obtain the compressed first object data. Then, the server stores the compressed first object data. It can be understood that the storage space can be saved by compressing and then storing the object data.
Wherein the updating process includes at least one of updating the number of files and updating the storage space.
The server is preset with a statistical table, which is used for counting the number of files in the directory where the object data is located, the number of files in the parent directory of the directory where the object data is located, the storage space of the directory where the object data is located, and the storage space of the parent directory of the directory where the object data is located.
After the first object data is stored, the number of files in the directory where the first object data is located, the number of files in the parent directory of the directory where the first object data is located, the storage space of the directory where the first object data is located and the storage space of the parent directory of the directory where the first object data is located are counted to obtain statistical information, and the statistical table is updated according to the statistical information.
In one embodiment, the remaining storage space of the directory where the first object data is located and the remaining storage space of the parent directory of the directory where the first object data is located are calculated; and if the residual storage space is lower than the preset space threshold, generating prompt information.
In the embodiment, the server receives the storage request, and stores the first object data according to the first image information in the storage request; generating a first metadata record according to the object information of the first object data and the first image information, and inserting the first metadata record into a metadata table; and then, updating the preset statistical table. In the embodiment of the disclosure, the statistical table is adopted to count the number of the files and the storage space, so that the real-time monitoring and early warning of the residual storage space can be realized, and the storage space can be better managed.
In an embodiment, as shown in fig. 5, on the basis of the above embodiment, an embodiment of the present disclosure may further include:
The retrieval request comprises second image information of the image to be retrieved.
The terminal receives an image retrieval condition input by a user, wherein the image retrieval condition comprises second image information of an image to be retrieved. Then, the terminal generates a search request according to the image search condition and transmits the search request to the server. Correspondingly, the server receives the retrieval request sent by the terminal.
For example, the terminal acquires the image search condition including the patient name and the image type, and then generates a search request according to the patient name and the image type, and sends the search request to the server. The server may then receive the patient name and image type.
And the server searches the metadata table according to the second image information. For example, the server looks up in a metadata table based on the patient name and image type.
If the metadata record corresponding to the second video information is found in the metadata table, step 403 is executed. And if the second metadata record corresponding to the second image information is not found in the metadata table, the server feeds back to the terminal that the image to be retrieved is not found.
In step 503, if the second metadata record corresponding to the second image information is found, the corresponding second object data is obtained according to the second metadata record.
If the server finds the second metadata record corresponding to the second image information, the server indicates that the second object data corresponding to the second image information is stored, and the server acquires the second object data according to the storage position of the object data in the second metadata record.
In an alternative embodiment, obtaining the corresponding second object data according to the second metadata record may include: searching a second metadata record in a preset statistical table to obtain statistical information corresponding to the second metadata record; if the second object data are determined to be high-frequency access data according to the statistical information, acquiring the second object data from a preset cache; and if the second object data are determined to be non-high-frequency access data according to the statistical information, acquiring the second object data from a preset storage space.
The preset statistical table also stores statistical information indicating whether the object data is high-frequency access data. After the server searches the second metadata record corresponding to the second image information in the metadata table, the server searches the second metadata record in the statistical table to obtain statistical information corresponding to the second metadata record. If the statistical information indicates that the second object data is high frequency access data, the second object data is read from the pre-cache. And if the statistical information indicates that the second object data is non-high frequency access data, reading the second object data from a preset storage space.
In one embodiment, after the second object data is read from the preset storage space, the second object data is stored in the preset buffer, and the statistical information corresponding to the second object data is updated, that is, the second object data is recorded as the high-frequency access data in the statistical table.
As can be appreciated, storing the high-frequency access data in the preset cache can improve the access performance of the object data.
And step 504, feeding back the second object data.
And after acquiring the second object data, the server sends the second object data to the terminal. Correspondingly, the terminal receives the second object data sent by the server.
In the above embodiment, the server receives the retrieval request; searching a metadata record corresponding to the second image information in a metadata table; if the second metadata record corresponding to the second image information is found, acquiring corresponding second object data according to the second metadata record; feeding back the second object data. In the prior art, when a doctor accesses a medical image, a server needs to search image index information in an index database first, and then object data is obtained according to the image index information; in the embodiment of the present disclosure, the metadata table of the storage engine stores the image information, so that the corresponding second object data can be directly found according to the second image information of the image to be retrieved. It can be seen that the retrieval speed of the disclosed embodiments is faster compared to the prior art.
In an embodiment, as shown in fig. 6, on the basis of the above embodiment, an embodiment of the present disclosure may further include:
The editing request comprises third image information of an image to be edited; the edit request includes at least one of an update request and a delete request.
When a doctor edits a medical image, the terminal receives an editing operation, such as an updating operation, a deleting operation and the like, for the image to be edited. And then, the terminal generates an editing request according to the editing operation and the third image information of the image to be edited and sends the editing request to the server. Correspondingly, the server receives the editing request sent by the terminal, and analyzes the editing request to obtain third image information of the image to be edited and editing operation to be executed.
And the server searches the metadata table according to the third image information. For example, if the third image information includes the image unique identifier of the image to be edited, the metadata table is searched for the image unique identifier. If the unique image identifier is found, it is determined that the metadata record where the unique image identifier is located is the metadata record corresponding to the third image information, and then step 603 is executed. And if the image identifier is not found, feeding back the editing failure to the terminal.
After the server finds the third metadata record corresponding to the third image information in the metadata table, the server may determine the third data object to be edited according to the unique identifier of the object data stored in the third metadata record and the storage location of the object data.
And when the editing request is an updating request, the editing request can also comprise updating information, and after the server determines the third object data, the server updates the third object data according to the updating information. And the server updates a third metadata record corresponding to the third object data in the metadata table according to the updating processing.
In a case where the edit request is a delete request, the server deletes the third object data. And the server also deletes a third metadata record corresponding to the third object data in the metadata table.
If the editing process is an updating process, the server feeds back the updating success to the terminal if the updating process is successful, and the updated third object data can also be sent to the terminal.
If the editing process is a deletion process, the server feeds back the deletion success to the terminal if the deletion succeeds.
In one embodiment, as shown in fig. 7, after step 604, the method may further include:
and step 606, if the editing processing fails, performing rollback processing on the third metadata record.
In the case where the editing process is the updating process, if the updating process fails, the server feeds back the updating failure to the terminal, and restores the third metadata record in the metadata table to the third metadata record before the updating process.
In the case where the editing process is a deletion process, if the deletion process fails, the server feeds back the deletion failure to the terminal and reinserts the deleted third metadata record into the metadata table.
The server is preset with a fault-tolerant storage space. And under the condition that the updating fails and the rollback processing on the third element data record fails, the server stores the third element data record before the updating processing into the fault-tolerant storage space.
And under the condition that the deletion processing fails and the rollback processing on the third element data record fails, the server stores the deleted third element data record into the fault-tolerant storage space.
It is to be understood that after the rollback processing for the third metadata record fails, the metadata records in the metadata table no longer correspond to the actual situation of the third object data. In response to this situation, the embodiment of the present disclosure uses the fault-tolerant storage, and may determine the third object data according to the third metadata record stored in the fault-tolerant storage space when the third object data is edited next time, and implement the editing of the third object data.
In the above embodiment, an edit request is received; searching a metadata record corresponding to the third image information in a metadata table; if the third metadata record corresponding to the third image information is found, determining third object data to be edited according to the third metadata record; editing the third object data according to the editing request, and updating a metadata table according to the editing processing; and if the editing processing is successful, feeding back an editing processing result. In the prior art, when a doctor edits a medical image, a server needs to search image index information in an index library first, and then obtain object data according to the image index information, and then can edit the medical image. In the embodiment of the present disclosure, the image information is stored in the metadata table of the storage engine, so that the corresponding third object data can be directly found according to the third image information of the image to be edited, thereby editing the medical image. It can be seen that the editing speed of the disclosed embodiments is faster compared to the prior art.
It should be understood that although the various steps in the flowcharts of fig. 2-7 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-7 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
