After the patient finishes shooting, the equipment sends the image data to the PACS system, and the PACS system uniformly forwards the image data to the platform front server by automatic routing. The front-end server deploys an image cloud gateway service to receive and analyze image data, uploads the image data to an image center storage resource pool and conducts index filing. In the face of the storage problem of massive medical images, according to the specifications executed by hospitals, the initial image data after the images are collected by different inspection instruments can be in a DICOM format, and the DICOM image file can be an object stored in a grading way.

And S102, matching the relevant information of the user by using a preset mapping relation, and determining the image characteristic information corresponding to the initial image data.

In this embodiment of the present disclosure, the preset mapping relationship may be preset to determine feature information corresponding to the initial image data, and specifically, the preset mapping relationship may represent a mapping relationship between each piece of relevant information and a feature tag, determine a feature tag matched with the relevant information according to matching of the relevant information of the user in the preset mapping relationship, and use the matched feature tag as image feature information corresponding to the initial image data.

Step S103, determining a target storage format and a target storage location indicated by the image feature information based on a preset partition storage policy.

In the embodiment of the present disclosure, the preset partition storage policy may be a partition storage policy set in advance according to different image feature information, and the preset partition storage policy may include different storage format requirements and different storage addresses. Specifically, a matching storage policy may be determined from preset partition storage policies according to the image feature information, a storage format corresponding to the matching storage policy is used as a target storage format, and a corresponding storage location is used as a target storage location.

And step S104, converting the initial image data according to a target storage format to obtain a target image file, and storing the target image file to the target storage position.

In the embodiment of the present disclosure, format conversion may be performed on the initial image data according to a target storage format to obtain a target image file in the target storage format, and the target image file may be stored in a target storage location indicated by the storage policy.

In summary, the data storage method provided in the embodiments of the present invention may first obtain initial image data acquired by an inspection instrument for a user and related information of the user, match the related information of the user by using a preset mapping relationship, determine image feature information corresponding to the initial image data, determine a target storage format and a target storage location indicated by the image feature information based on a preset partition storage policy, convert the initial image data according to the target storage format to obtain a target image file, and store the target image file to the target storage location. Therefore, on one hand, the storage strategy is determined according to the characteristic information of the acquired image data, the problem that the transmission time is long due to the fact that the image file is directly stored can be avoided, waste of transmission resources can be avoided, on the other hand, different partition storage strategies can be determined according to different characteristic information, the requirement for diversified storage of the image file can be met, unified standards can be provided for various applications, the relevant data of medical images can be retrieved quickly at any time, information barriers are broken, and the transmission efficiency of the image file is improved.

Optionally, in this embodiment of the present disclosure, the operation of matching the relevant information of the user by using a preset mapping relationship and determining image feature information corresponding to the initial image data may specifically include:

In the embodiment of the present disclosure, the matched feature information may be determined in the preset mapping relationship according to the image generation time of the acquired initial image data, for example, if the image generation time is later than a first preset time, the corresponding image feature information may be determined to be primary feature information, and the partition storage policy corresponding to the primary feature information is a primary storage policy; if the image generation time is between the first preset time and the second preset time, determining that the corresponding image characteristic information is secondary characteristic information, and determining that the partition storage strategy corresponding to the secondary characteristic information is a secondary storage strategy; if the image generation time is earlier than the second preset time, it may be determined that the corresponding image feature information is the third-level feature information, and the partition storage policy corresponding to the third-level feature information is the third-level storage policy. The first preset time and the second preset time may be preset according to actual conditions.

In this embodiment of the disclosure, the feature information matched in the preset mapping relationship may be determined according to a recent access frequency of the user, for example, the recent access frequency is smaller than a preset frequency minimum value, the feature information matched by the user is determined to be primary feature information, the recent access frequency is greater than the preset frequency minimum value and smaller than a preset frequency maximum value, the feature information matched by the user is determined to be secondary feature information, the recent access frequency is greater than the preset frequency maximum value, and the feature information matched by the user is determined to be tertiary feature information, where the preset frequency maximum value and the preset frequency minimum value may be preset according to an actual situation.

Optionally, in the embodiment of the present disclosure, the operation of determining the target storage format and the target storage location indicated by the image feature information based on the preset partition storage policy may specifically include:

In the embodiment of the present disclosure, the primary storage policy may be for the situation that the requirement of a user on the convenience of viewing the image file is higher and the requirement of professional viewing of the image file is general, the preset image format indicated by the primary storage policy may be the image format such as jpg, png, and the like, and the storage location indicated by the primary storage policy may be a preset database to meet the requirement of querying the electronic films of patients and families, and accordingly, the initial image data may be directly converted into the preset image format indicated by the primary storage policy, so as to obtain the target image file in the preset image format, and store the target image file to the target storage location indicated by the primary storage policy.

if the image characteristic information corresponds to a secondary storage strategy, taking a preset compression format indicated by the secondary storage strategy as the target storage format, and taking a storage position indicated by the secondary storage strategy as the target storage position.

In the embodiment of the disclosure, the secondary storage policy may be a condition that a user generally requires convenience for viewing an image file and also needs to professionally view the image file, for example, the secondary storage policy is used for requirements of a clinician for review, remote diagnosis and consultation, a preset compression format indicated by the secondary storage policy may be a standard lossless compression dicom file, and a storage position indicated by the secondary storage policy may be a mixed cloud mode of private file storage and cloud storage, so that an image of a called patient can be conveniently stored, an image diagnosis report can be given, or image diagnosis results of other doctors can be audited, and a diagnosis report can be issued. Accordingly, the initial image data may be directly converted into a preset compression format indicated by the secondary storage policy to obtain a target image file in the preset compression format, and the target image file may be stored in a target storage location indicated by the secondary storage policy.

In the embodiment of the present disclosure, the third-level storage policy may be for a user to perform professional viewing on only an image file, for example, for requirements of clinical scientific research, teaching, and diagnosis of difficulty, the preset lossless format indicated by the third-level storage policy may be a marked or post-processed high-definition lossless dicom file, and the storage location indicated by the third-level storage policy may be a public cloud storage location. Accordingly, the initial image data may be converted into a predetermined lossless format indicated by the three-level storage policy, so as to obtain a target image file in the predetermined lossless format, and the target image file may be stored in a target storage location indicated by the three-level storage policy.

In the embodiment of the disclosure, from the two aspects of solving the problems of fast retrieval of mass medical image data storage, reducing file transmission time, reducing resource internal consumption and relieving resource internal consumption, a method for performing three-level partition storage based on different image types is provided for the defects of the existing storage management scheme. The method comprises the steps of storing data files with different enthusiasm in storage engines with different levels by taking image generation time, recent access frequency and storage equipment load as main granularity, and performing unified management and scheduling on medical image data by utilizing a three-level partition grading storage method according to the use categories of the image data use scenes to realize mass image data storage and rapid data retrieval. First, the storage engine functionality can be extended. Based on the consideration of the lateral expansion capability of the three-level partition storage management, data of different file storage services are abstracted, and distributed storage is performed at a server side. In the face of the storage problem of massive medical images, according to the specifications executed by hospitals, the reconstruction data acquired by different inspection instruments are in a DICOM format, and a DICOM image file is an object stored in a grading way. The service of the cloud platform is decoupled from the specific storage engine of the image file, the key functions of data storage management, authorization information, log report forms and the like are absorbed, and a closed loop space for image partition storage is formed. Second, a partition storage policy scheme may be preset. The three-level partition storage management method interacts with data of the image platform, schedules and manages data in the cloud storage engines of different levels at the bottom layer, and receives basic management of the storage engines at the bottom layer, the storage engines of different levels are virtualized into a series of different storage nodes in a storage pool, and the management of the storage nodes comprises some basic operations such as addition and deletion of the nodes, monitoring of the running state of the nodes, adjustment of loads and the like. And further, reading the file, marking the image data, the patient data and the examination data as image information according to the mapping relation, and sending the image information, the patient data and the examination data to a database for three-level partition storage.

In the embodiment of the disclosure, compared with the existing storage management method, the method for storing and managing medical image data in three levels of partitions provided by the disclosure can partition and intercept DICOM images based on image cloud service, provide unified standards for various applications, and can quickly retrieve related data of medical images at any time to break information barriers. The corresponding important images are sent to the patient end or the doctor end according to the use scene of the user, and the situation that other unimportant images in the electronic images are sent to the patient end or the doctor end to influence the transmission efficiency is avoided. On the one hand, a clinician can quickly read the image, and the previous diagnosis information of the patient is divided into different hospitals under the data barrier, so that the diagnosis information is incomplete, not continuous and inaccurate, the diagnosis quality is influenced, and the value of medical data cannot be effectively mined. Through the image cloud service, data collected by a PACS (or an image device) of a hospital are uploaded to the cloud, so that the centralized storage and the centralized management of images are realized, and simultaneously, source data are stored in different resource pools by means of a three-level distinguishing storage method. In the diagnosis process of a clinician, the original high-definition image library generated by storing and indexing is established by requesting to access the DICOM file through the API interface, so that the image data of a patient can be quickly and conveniently retrieved, and the image data can be checked for diagnosis and analysis and the like. On the other hand, the electronic film can be conveniently and quickly checked by a mobile phone of a patient, the cloud storage is carried out on the patient image and the diagnosis report which are collected by the front-end processor, the image data center subprocess analyzes the image and carries out lossy compression, and jpg and png pictures are generated. After a patient finishes shooting in a hospital, the patient does not need to wait for an electronic film printing report, can quickly check film pictures and diagnosis reports at a mobile phone end after receiving a prompt from the hospital, and does not need to influence transmission efficiency due to overlarge source files.

For example, fig. 2 schematically illustrates a schematic diagram of data storage provided by an embodiment of the present disclosure, as shown in fig. 2, S201, acquiring initial image data; s202, determining corresponding image characteristic information; s203, converting according to a primary storage strategy to obtain a target storage file; s204, storing the data to a storage position indicated by a primary storage strategy; s205, converting according to a secondary storage strategy to obtain a target storage file; s206, storing the data to a storage position indicated by the secondary storage strategy; s207, converting according to a three-level storage strategy to obtain a target storage file; s208, storing the data to a storage position indicated by the three-level storage strategy; and S209, calling the target image file by different scenes.

An exemplary implementation is specifically: firstly, accessing data, wherein the data comprises initial image data and related information, the initial image data can be a standard DCM file, and the related information can be basic information of a patient, report data, a key image SOP Instance UID, a PDF report FTP/HTTP download address.

After the patient finishes shooting, the equipment sends the image data to the PACS system, and the PACS system uniformly forwards the image data to the platform prepositive server by automatic routing. The front-end server deploys an image cloud gateway service to receive and analyze image data, uploads the image data to an image center storage resource pool and conducts index filing.

And thirdly, the DICOM application service, namely a Dicom application service cluster (data uploading/returning), is mainly used for image access, compression, transmission and management, and the image center main process performs archiving storage management on the original DICOM, so that the whole platform performance architecture is stable. a) The method supports standard dicom3.0 protocol to collect image images from PACS or equipment, and comprises standard dicom equipment such as CT, MR, DR, CR, MG, DSA and the like; b) Ultrasound/endoscopic images are typically stored as picture formats in PACS or devices, converted into standard dicom files (compressed standard Transfer Syntax uid1.2.840.1008.1.2.4.70, transfer Syntax uid.2.840.1008.1.2.4.50), uploaded in dicom and original picture 2 ways. c) And synchronous index data through a standard interface of an image cloud data exchange platform is supported. d) Patient information, examination order information and image report information are collected in an interface or database view mode and uploaded according to an image cloud data exchange platform standard interface mode.

And then, analyzing the DICOM file in a three-level partition mode to realize quick retrieval, processing image information by a main process of the image center after the front-end server uploads an image to an image data center, and realizing the processing, data transmission, analysis and the like of the image by using a DICOM standard open source realization library dcm4 cache. The dem4che is an open source toolkit for clinical image and object management developed based on java language, provides good support for DICOM standard and HL7 standard, follows service-oriented architecture (SOA) design, supports service modularization design, provides a plurality of functional modules, such as a WEB-based user interface, an interface of the DICOM standard, an interface of the HL7 standard, a WEB access (Web access object, WADO) interface of the DICOM object, an audit trail and node authentication record log and the like provided in IHE, intercepts and distributes DICOM image and image data, and compresses and stores source data by subprocesses to respectively store the source data into different resource pools.

And finally, image data retrieval, namely acquiring indexes from an image cloud data exchange platform, providing a standard DICOM3.0 protocol and a WADO protocol for the PACS system to retrieve, and providing different resource pool data images according to API (application program interface) response. Through the above example, especially in the file analysis embodiment, for receiving the DICOM image and the visible data of the image and performing partition processing, the DICOM image after being partitioned is fed back and sent to the sub-process image processing module, the three-level partition storage management method researched by the invention is adopted, so that the retrieval of different scene applications such as patient, doctor diagnosis, remote teaching and the like is provided, and mass storage and quick retrieval are realized.
