Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The medical image data storage method provided by the embodiment of the application can be applied to an application environment shown in fig. 1, and fig. 1 is an application environment diagram of the medical image data storage method provided by the embodiment of the application. Wherein the proxy server 102 communicates with the computer device 101 and the server 103 via a network. The server 103 is a PACS server. The proxy server 102 receives the write request of the target medical image file sent by the computer device 101, determines a target server from the servers 103 according to the target tag information and the routing rule table, and further stores the target medical image file to the target server. Wherein the computer device 101 may be, but is not limited to, various personal computers, notebook computers, tablet computers, and the like. The number of servers 103 is plural.
In one embodiment, as shown in fig. 2, fig. 2 is a flowchart of a medical image data storage method according to an embodiment of the present application, and the method is applied to the proxy server 102 in fig. 1 for illustration, and includes the following steps:
S201, receiving a writing request of a target medical image file sent by computer equipment, wherein the writing request comprises target label information of the target medical image file.
In the embodiment of the application, the target medical image file may be digital imaging and communication (DIGITAL IMAGING AND Communications IN MEDICINE, DICOM) data, which is an international standard for medical images and related information, and defines a medical image format that can be used for data exchange and satisfies clinical needs. The DICOM data may include hierarchical information corresponding to the medical image file and/or identification information of the medical institution. The hierarchy information may include a case number of the subject to which the medical image file corresponds, an examination site, a data type of the medical image file, and the like. The data types include, for example, CT data types, MR data types, US data types, and the like. CT (Computed Tomography), i.e., electron computer tomography. MR (Magnetic Resonance), magnetic resonance. US examination is an ultrasound examination in which reflection of ultrasound waves is observed by a human body, and is generally called US, and the type of data acquired by using the US examination technique is called US data type. The identification information of the medical institution may be an institution name of the medical institution, geographical location information of the institution, and the like.
The target label information may include hierarchical information corresponding to the target medical image file and/or identification information of the medical institution, etc.
In the embodiment of the application, if a certain target medical image file needs to be written into the PACS server, the computer equipment can send a writing request of the target medical image file to the proxy server, and correspondingly, the proxy server receives the writing request of the target medical image file sent by the computer equipment.
S202, determining a target server from the candidate servers according to the target tag information and a routing rule table, wherein the routing rule table comprises the tag information of the medical image file and routing rules among the candidate servers, and the routing rules are set according to the retrieval requirement of the medical image file.
In this step, the proxy server determines a target server from among the candidate servers according to the target tag information and the routing rule table. As shown in fig. 3, fig. 3 is a block diagram of a proxy server according to an embodiment of the present application. APISIX, APISIX Java/Go plug in Runner, DICOM plug-in module (DICOM Plugin module), DICOM protocol module may be deployed in the proxy server. The routing rule table can be deployed in a database of the proxy server or in other database servers. The routing rule table may be configured in the proxy server, the routing rule in the routing rule table configured in the proxy server may be read, or the routing rule may be written into the proxy server.
The APISIX is a high-performance and extensible micro-service API gateway, and provides rich flow management functions such as load balancing, dynamic upstream, gray level release, service fusing, identity authentication, observability and the like. Based on nginx (openresty) and Lua realizing functions, the idea of Kong is used for substituting a relational database (Postgres) of the bottom layer of Kong with an etcd of NoSQL type, so that compared with Kong, the performance of APISIX is greatly improved, and the performance of Apache APISIX is higher under the condition of starting various plug-ins.
And under the condition that the label information is the data type corresponding to the target medical image file, the routing rule between the label information of the medical image file and each candidate server is the corresponding relation between the data type of the medical image file and each candidate server. For example, each candidate server includes candidate server a, candidate server B, and candidate server C, where if candidate server a corresponds to a CT data type, candidate server B corresponds to an MR data type, and candidate server C corresponds to an US data type. And if the data type included in the target tag information is the MR data type, taking the candidate server B as the target server. And if the data type included in the target tag information is the US data type, taking the candidate server C as the target server.
Optionally, if the target tag information includes hierarchy information corresponding to the target medical image file and identification information of the medical institution, the target server may be determined from the candidate servers according to the hierarchy information, the identification information of the medical institution and the routing rule table.
For example, the hierarchy information includes a data type of a medical image file, the identification information of the medical institution is an institution name of the medical institution, and if the candidate server corresponding to the institution name a includes the candidate server a and the candidate server B, and the candidate server corresponding to the CT data type is the candidate server B and the candidate server C, the candidate server B is taken as a target server, that is, an intersection of the candidate server corresponding to the identification information of the medical institution and the candidate server corresponding to the hierarchy information is taken as a target server.
The medical image file retrieval requirement refers to a requirement that a doctor or other person retrieve a medical image file. For example, if a doctor wants to review all medical image files of the same patient, the routing rule may be set according to the case number of the patient, for example, the medical image files of the patient corresponding to the odd case number checked in a plurality of hospital areas are stored in the server a, and the medical image files of the patient corresponding to the even case number checked in a plurality of hospital areas are stored in the server B.
For another example, if a doctor needs to review medical image files of a patient at all hospitals in a particular city, the routing rules may be configured to store the medical image files according to the geographic location information of the hospital. For example, medical image files of all examinations of a patient in a city are stored in the server a, and medical image files of all examinations of a patient in B city are stored in the server B. If a doctor needs to review all the medical image files of the patient in a city, the required medical image files can be read from the server a.
S203, storing the target medical image file in a target server.
In connection with the above illustration, if the data type included in the target tag information is the MR data type and the candidate server B is the target server, the target medical image file is stored in the candidate server B.
According to the medical image data storage method provided by the embodiment of the application, the writing request of the target label information comprising the target medical image file sent by the computer equipment is received, the target server is determined from the candidate servers according to the target label information and the routing rule table, and the target medical image file is further stored in the target server, wherein the routing rule in the routing rule table is set according to the retrieval requirement of the medical image file. Because the embodiment of the application does not store the checked medical image file in the PACS server corresponding to the hospital, but can determine the target server according to the target label information and the routing rule table, the medical image file is stored in the target server according to the medical image file retrieval requirement, after the medical image file is stored by using the storage method, if the medical image file needs to be read, the medical image file is read from the target server, and the retrieval request is not required to be sent to other hospital areas, so that the retrieval efficiency of the medical image file is improved. For example, a doctor may review all medical image files of a patient who is examined in a plurality of hospital areas of a certain medicine, and the routing rule may be set to be set according to the case number of the patient, for example, medical image files of patients corresponding to an odd case number examined in a plurality of hospital areas are stored in the server a, and medical image files of patients corresponding to an even case number examined in a plurality of hospital areas are stored in the server B. If the doctor needs to read all medical image files of the same patient, if the case number of the patient is an odd number, all medical image files of the patient can be obtained from the server A, and the PACS servers in a plurality of hospital areas do not need to read the medical image files.
Referring to fig. 4, fig. 4 is a flowchart of a method for determining a target server according to an embodiment of the present application. The embodiment of the application relates to a possible implementation manner of determining a target server from candidate servers according to target label information and a routing rule table under the condition that the hierarchy information comprises a first identification of a target subject corresponding to a target medical image file. The routing rule in this embodiment is a rule set according to a medical image file retrieval requirement, for example, a doctor needs to retrieve all medical image files of the same patient (subject). Based on the above embodiment, the step S202 includes the following steps:
S401, performing modular operation on the total number of the candidate servers by the first identification to obtain a modular operation result.
In this step, the first identification of the subject is, for example, the case number of the subject (PATIENT ID). The case number performs modulo operation on the total number of candidate servers, for example, the case number of patient a is 1, the case number of patient B is 2, the case number of patient C is 3, the case number of patient D is 4, the case number of patient E is 5, and the total number of 3 candidate servers are candidate server a, candidate server B and candidate server C, respectively. Then, according to the modulo operation calculation formula adopted by the modulo operation of a to b, the modulo operation result obtained by the modulo operation of the case number 1 on the total number 3 is 1, the modulo operation result obtained by the modulo operation of the case number 2 on the total number 3 is 2, the modulo operation result obtained by the modulo operation of the case number 3 on the total number 3 is 0, the modulo operation result obtained by the modulo operation of the case number 4 on the total number 3 is 1, and the modulo operation result obtained by the modulo operation of the case number 5 on the total number 3 is 2.
The modular arithmetic calculation formula is r=a-c×b, wherein a represents a dividend, b represents a divisor, and c represents an integer quotient result obtained by dividing a by b.

If the correspondence between the modulo operation result included in the routing rule table and the candidate server is shown in table 1 below, taking the first identifier of the target subject as 7 as an example, after determining that the modulo operation result obtained by performing the modulo operation on the total number 3 by 7 is equal to 1 in S401, the candidate server B may be taken as the target server according to the modulo operation result and table 1.
If the first identifier of the target subject is equal to 8, the above S401 determines that the modulo operation result obtained by performing the modulo operation on the total number 3 of 8 is equal to 2, and then the candidate server C is taken as the target server.
If the first identifier of the target subject is equal to 9, and the modulo operation result obtained by performing the modulo operation on the total number 3 by 9 is equal to 0, the candidate server a is taken as the target server.

| 0 | Candidate server A |
| 1 | Candidate server B |
| 2 | Candidate server C |

determining a target server from the candidate servers according to target tag information and a routing rule table which are included in the read request, wherein the routing rule table comprises the tag information of the medical image file and routing rules among the candidate servers;
and reading the target medical image file from the target server.
In this embodiment, the method for determining the target server by the proxy server is the same as the method provided in the above embodiment, and will not be described here again.
The process of reading the target medical image file from the target server may be shown in fig. 8, and fig. 8 is a schematic diagram of a process of reading the target medical image file according to an embodiment of the present application. The 3 DICOM read applications include, for example, a read application 1 deployed at a computer device 1, a read application 2 deployed at a computer device 2, and a read application 3 deployed at a computer device 3. The reading application 1 is to read PATIENT ID the ① and ④ medical image files, the reading application 2 is to read PATIENT ID the ② medical image file, and the reading application 3 is to read PATIENT ID the ③ medical image file. If ①、②、③、④ is a storage method corresponding to the embodiment of fig. 5, that is, the medical image file corresponding to the odd number PATIENT ID is stored in PACS-S1 and the medical image file corresponding to the even number PATIENT ID is stored in PACS-S2, the proxy server obtains PATIENT ID the medical image file with the odd number from PACS-S1 and obtains PATIENT ID the medical image file with the even number from PACS-S2.
It should be noted that, the medical image file storage method in the conventional technology may cause a problem that the server is overloaded when the medical image file is read, and the medical image file reading efficiency is low. For example, if 100 patients are checked in hospital a, hospital B and hospital C, the medical image files related to the check in hospital a are stored in PACS server a corresponding to hospital a, the medical image files related to the check in hospital B are stored in PACS server B corresponding to hospital B, and the medical image files related to the check in hospital C are stored in PACS server C corresponding to hospital C. If the 100 patients arrive at the general hospital of the hospital a to see the doctor, if the doctor needs to review all the medical image files of the patient, 300 review requests are required to be sent to the PACS server A, PACS server B and the PACS server C, so that the medical image files of the 100 patients are read.
By adopting the method of the embodiment, if the case numbers of the 100 patients are all odd, the medical image files of the 100 patients are all stored in a PACS server, and then the medical image files of the 100 patients can be read only by sending 100 retrieval requests to the PACS server. Obviously, the method provided by the embodiment can reduce the number of the transmitted retrieval requests, and the more obvious the number of the transmitted retrieval requests is reduced under the condition that the number of patients is larger, so that resources required by the server for transmitting the retrieval requests can be saved.
Finally, it should be noted that, a proxy server as shown in fig. 9 may also be used, and fig. 9 is a block diagram of another proxy server according to an embodiment of the present application. The key point of APISIX is that based on Nginx, APISIX can be replaced by other means to realize the method, for example, APISIX is replaced by OpenResty or native Nginx, and a plug-in module of DICOM and a corresponding protocol can be realized by using a plug-in mechanism of the plug-in module. The OpenResty is an "enhanced packet" based on the nginnx, which not only supports HTTP/HTTPs, but also can conveniently and quickly build a dynamic gateway, and can be used as an application container to write business logic.
It should be understood that, although the steps in the flowcharts related to the above embodiments are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
