[0040] With the development of technology, medical imaging equipment is increasingly widely used clinically. How to efficiently store medical images is of crucial importance. Currently, the hospital system uses a single-machine method to store medical images. When transmitting medical images, once the instance network breaks, the files will be lost or cannot be retrieved, resulting in low file availability.

[0041] There are many distributed file storage systems, such as HDFS (Hadoop Distributed File System), GFS (Google File System), Lustre (Distributed Parallel File System), etc., which can handle stored files in their respective fields. However, they cannot well support the transmission, storage, retrieval, etc. of medical images, and cannot perform real-time queries and efficiently store a large number of small files.

[0042] In view of this, the present application proposes a distributed storage and query method for medical image data, which can effectively solve the problems of file loss and inability to retrieve caused by the existing medical image storage method, reduce the risk of file storage, and improve the stability and availability of medical image data storage.

[0043] The embodiment of the present application provides a distributed storage and query method for medical image data. The medical image data is distributedly stored through data communication between the first server and the second server. When the network communication state of the first server is in a connectable state, the first server receives the medical image data and stores it. Then, when it is determined that the network communication state of the second server is in a connectable state, the first server sends the medical image data to be stored to the second server for storage, so as to ensure that the first server and the second server synchronously store the medical image data, which can reduce the risk of file storage and improve the stability and availability of medical image data storage.

[0044] When there are multiple servers, the user sends medical image data to any server in a connectable state for storage, and this server sends the medical image data to be stored to the other connectable servers for storage, so as to ensure that the other servers synchronously store the medical image data, reduce the risk of storing files on a single machine, and improve the stability and availability of medical image data storage.

[0045] Figure 1 The flowchart of the distributed storage and query method for medical image data according to an embodiment of the present application is shown.

[0046] As Figure 1 shown, the distributed storage and query method 100 for medical image data provided by the embodiment of the present application includes steps S110 to S130. This method is executed, for example, by any one of multiple servers, for example, by the first server.

[0047] Taking multiple servers as an example, when the servers include server A and server B, the first server can be one of the multiple servers (such as server A), and the second server can be the remaining servers (such as server B). When the servers include server A, server B, and server C, the first server can be one of the multiple servers (such as server A), and the second server can be the remaining servers (such as at least one of server B and server C).

[0048] Step S110, when the network communication state of the first server is in a connectable state, receive the medical image data to be stored.

[0049] Exemplarily, the server can be installed and configured on different computers, and network connectivity and data transmission are carried out through a communication protocol. The first server is connected to the user terminal by real-time reading of connection information. The connection information can be, for example, the IP address, port, and AE_TITLE (device identifier) of the first server. The user terminal can be, for example, a medical instrument, software and hardware equipment, etc. Based on the network connectivity state, the first server can receive medical image data automatically sent by an external device or receive the medical image data to be stored manually sent by the user terminal. For example, the medical image data can be received in the common Dicom format for medical images.

[0050] Step S120, store the medical image data to be stored in the first server.

[0051] Exemplarily, the medical image data includes at least one of the structural data of the medical image file, patient information, and medical diagnosis and treatment identification information, and the received medical image data is stored in the first server.

[0052] Step S130: When it is determined that the network communication status of the second server is in a connectable state, send the medical image data to be stored to the second server for storage.

[0053] Exemplarily, establish network connectivity with the second server through the first server, that is, create communication between the two instances. When it is determined that the network communication status of the second server is in a connectable state, the first server sends the medical image data containing the above information to the second server for storage, so as to ensure that the second server can synchronously store the medical image data and improve the stability and availability of the storage of medical image data.

[0054] The embodiment of the present application provides a method for distributed storage and query of medical image data. The medical image data is distributedly stored through data communication between the first server and the second server. When the network communication status of the first server is in a connectable state, the first server receives the medical image data and stores it. Then, when it is determined that the network communication status of the second server is in a connectable state, the first server sends the medical image data to be stored to the second server for storage, so as to ensure that the first server and the second server synchronously store the medical image data. The medical image data to be stored only needs to be sent to any one of the servers, and the server automatically sends the stored data to the other servers for automatic distributed storage, effectively improving the storage efficiency, reducing the risk of file storage, and improving the stability and availability of the storage of medical image data.

[0055] In another example, each server includes multiple functional units to support the availability of the entire distributed storage function. Taking three servers as an example, to ensure the availability of the distributed function, it is required to install three servers on at least three computers respectively, receive different data information, perform corresponding distributed storage or query the stored files.

[0056] Exemplarily, storing the medical image data to be stored in the first server includes: first, parsing the medical image data to be stored to generate medical image parsing data, where the medical image parsing data includes at least one of the structure data of the medical image file, patient information, and medical diagnosis and treatment identification information; then storing the medical image parsing data in the first server.

[0057] In the technical solution of the embodiment of the present application, when the network communication status of the first server is in a connectable state, the medical image data sent by the user is parsed to extract important information and generate medical image general format data that meets the requirements of storage and query, and then the parsed data is stored, which can efficiently store and query medical image data and improve the stability and availability of the storage of medical image data.

[0058] First, an example of the basic functional units of the server is described in conjunction with Figure 2 Figure 1 shows a schematic diagram of the basic functional units of the server according to an embodiment of the present application.

[0059] Figure 2 Figure 1 shows a schematic diagram of the basic functional units of the server according to an embodiment of the present application.

[0060] Exemplarily, the server may include a heartbeat unit, a warning unit, a transmission unit, a parsing unit, a storage unit, a retrieval unit, and a configuration unit.

[0061] The heartbeat unit is used to create protocol communication between each instance (the first server and the second server), monitor the network connectivity of each instance. Once it is found that a certain instance cannot be detected by all other instances for heartbeat or respiration (that is, the instance cannot survive and the network connectivity of the server is lost), the information of this server is handed over by other instances to their own warning units.

[0062] The warning unit is used to send an alarm when receiving the information that the heartbeat of a certain instance is lost; the transmission unit is used to transmit image data in accordance with the DICOM protocol commonly used in medical images.

[0063] The parsing unit is used to parse the medical image data sent by the user received by the transmission unit and create a file index, and send the parsing information and the index information to the storage unit for processing. The parsing information may be, for example, at least one of the structural data of the medical image file, user information (patient information, such as patient name), and examination number (medical diagnosis and treatment identification information). The index information may be, for example, the examination number (medical diagnosis and treatment identification information) and the patient name.

[0064] The storage unit is used to store the information of the medical image file, the index information, and the file path.

[0065] The retrieval unit is used to extract the index according to the index information and determine the retrieval rule. For example, it can retrieve according to the patient name.

[0066] The configuration unit is used to obtain the configuration information of the server, such as the IP address, port, AE_TITLE, heartbeat monitoring time, heartbeat loss reconnection times, etc. of the instance node. By storing medical image data distributively and querying in real time through each functional unit, it is possible to efficiently store medical image data and improve the stability and availability of medical image data storage.

[0067] Exemplarily, while parsing the medical image data to be stored, an index may also be created according to the medical image data to be stored to generate index information; and the index information is stored in the first server, where the index information is stored in association with the medical image parsing data.

[0068] Specifically, the index information can be, for example, the examination number (medical diagnosis and treatment identification information) related to the stored medical image data, the patient's name (patient information), etc. The parsing unit of the first server creates an index based on the medical image data, generates index information, stores the index information in the storage unit of the first server, and then the retrieval unit extracts the index according to the index information for retrieving the medical image data.

[0069] In the technical solution of the embodiment of the present application, while parsing the received medical image data to be stored, an index is created according to the medical image data, index information is generated, and the index information is associated and stored with the medical image parsing data in the first server for the user to read and query the stored medical image data in real time, which can efficiently store the medical image data and improve the stability and availability of the medical image data storage.

[0070] Then, when it is determined that the network communication state of the second server is in a connectable state, the first server sends the medical image data to be stored to the second server for storage.

[0071] Exemplarily, first, a connectivity detection is performed on the second server. For example, the first server can create a communication instance, and the second server can create another communication instance. The connectivity detection can be, for example, directly creating a communication between the two instances through the heartbeat unit of the first server and performing a heartbeat detection, or the heartbeat unit of the first server can obtain the instance heartbeat of the second server through other remaining servers to obtain the detection result; when the detection result indicates that the network communication state of the second server is in a connectable state, that is, when the first server can directly detect the heartbeat of the second server, or when the first server can detect the heartbeat of the second server through the remaining servers, the first server establishes a data communication with the second server and sends the medical image data to be stored to the second server for storage.

[0072] In addition, the method for performing a connectivity detection on the server is not limited to the above one. It is also possible to detect the network connectivity of the server through other general network communication methods before transmitting the medical image data for fault troubleshooting. For example, a detection instruction can be sent to the second server, and based on the response received from the second server, the network communication state of the second server can be obtained, which will not be elaborated here.

[0073] The following describes how the first server establishes a data communication with the second server and performs a distributed storage of the medical image data. Refer to the following text Figure 3 and Figure 4 .

[0074] Figure 3Shows the connectivity detection schematic diagram of the embodiment of the present application.

[0075] As Figure 3 shown, Server 1, Server 2, and Server 3 are three servers. The servers can directly communicate and connect based on http (Hypertext Transfer Protocol). When the http connection between Server 1 and Server 3 is disconnected, the status (returned status) of Server 3 recorded by Server 1 at this time is 0, and the status of Server 1 recorded by Server 3 is 0; the http connections between Server 1 or Server 3 and Server 2 are not disconnected, then Server 2 records the statuses of Server 1 and Server 3 as 1; Server 1 obtains the status of Server 3 as 1 through Server 2. Based on the "or" relationship, 1||0 = 1, that is, Server 1 is connected to Server 3 or Server 2 is connected to Server 3. Therefore, correct the status of Server 3 recorded by this node and reset it to 1 (similarly for Server 3, correct the status of Server 1 to 1). Currently, a complete communication can still be established among the three servers for distributed storage.

[0076] And when the http connection between Server 2 and Server 3 is also disconnected, Server 2 records the status of Server 3 as 0, and Server 1 also records the status of Server 3 as 0. Based on the "or" relationship, 0||0 = 0. At this time, it is considered that the heartbeat of Server 3 is lost, that is, Server 3 cannot perform network connectivity.

[0077] Figure 4 Shows the medical image data storage schematic diagram of the embodiment of the present application.

[0078] As Figure 4 shown, the first server reads the connection information of each server in the configuration information in real time. Server 1, Server 2, and Server 3 are three servers, and 192.168.1.1:8080:dcm, 192.168.1.2:8081:dcm, 192.168.1.3:8082:dcm are the connection information of each server. Dicom is a file in the general format of medical image data.

[0079] The user sends medical image data to any server in a network-connected state. This server serves as the first server. For example, if Server 1 is used as the first server, the transmission unit of Server 1 directly receives the medical image data to be stored, and then sends it to the parsing unit, storage unit, and retrieval unit for processing in sequence, so that the medical image data is stored in Server 1 (the first server).

[0080] Then, obtain the configuration information of Server 2 and Server 3 (the second server) through the configuration unit of Server 1 (the first server), and perform heartbeat detection on their respective connections. If both Server 2 and Server 3 are in a network-connected state, send the medical image data to be stored to Server 2 and Server 3 for storage through the transmission unit of Server 1, so as to ensure that the medical image data is synchronously stored on Server 2 and Server 3, improve the storage efficiency, reduce the risk of file storage, and improve the stability and availability of medical image data storage.

[0081] Exemplarily, in the case where the detection result indicates that the network communication state of the second server is in a non-connected state, an alarm signal indicating that the second server cannot be connected is output.

[0082] In the technical solution of the embodiment of the present application, when the heartbeat of the second server cannot be detected by the first server, that is, when the heartbeat detection result indicates that the network communication state of the second server is in a non-connected state, the first server sends the network connection information of the second server to its own warning unit, and the warning unit of the first server outputs an alarm signal indicating that the second server cannot be connected to the user side, which can timely process the server with network anomalies, reduce the risk of file storage, and improve the stability and availability of medical image data storage.

[0083] In another example, the first server can query medical image data. First, in the case where the network communication state of the first server is in a connectable state, receive the query information; then, based on the query information, perform a retrieval based on the index information to obtain the medical image analysis data corresponding to the query information, and output the medical image analysis data.

[0084] In the technical solution of the embodiment of the present application, when the first server is in a network-connected state, it receives the query information, performs a data file retrieval through the retrieval unit, generates and outputs a file stream according to the retrieved data information (medical image analysis data), so that the output end can read and query the medical image data accordingly, improving the availability of the medical image data.

[0085] Figure 5 Shows the flowchart of the method for querying medical image data according to the embodiment of the present application.

[0086] As Figure 5 shown, the method 500 for querying medical image data provided by the embodiment of the present application includes steps S510 to S520. This method can be executed by the client. The client can send the query information to any one of multiple servers. Taking the client sending the query information to the first server as an example.

[0087] Step S510: When the network communication status of the first server is in a connectable state, send the first query information to the first server.

[0088] Exemplarily, the first query information matches the index information stored in the first server. The first query information can be, for example, the query conditions for medical image data sent via the http protocol (Hypertext Transfer Protocol), c-find protocol (query service protocol), c-get protocol (acquisition service protocol), Dicom protocol, or ftp protocol (File Transfer Protocol) based on a pre-designed C-STORE (columnar storage system) database. When the network communication status of the first server is in a connectable state, send the query information to the first server to obtain medical image data.

[0089] Step S520: Receive the medical image data output by the first server in response to the first query information.

[0090] Exemplarily, the client sends query information to the first server and receives the relevant medical image data retrieved by the first server based on the query information. For example, it can receive the medical images or medical image addresses sent by the first server using the C-SCU protocol (consumer service protocol).

[0091] In the technical solution of the embodiments of the present application, by establishing network connectivity between the client and the first server and sending the first query information, the first server satisfies the method in the above-described implementation manner, and thus receives the relevant medical image data output by the first server based on the first query information, enabling real-time query of the stored medical image data and improving the stability and availability of medical image data storage.

[0092] Exemplarily, when the network communication status of the first server is in a non-connectable state, send the second query information to the second server; then receive the medical image data output by the second server in response to the second query information.

[0093] The following specifically describes how the client queries the medical image data stored in the server. Refer to the following text. Figure 6 .

[0094] Figure 6 Shows a schematic diagram of medical image data query in the embodiments of the present application.

[0095] As Figure 6As shown, when the client API (Application Programming Interface) performs a file query, it establishes a network connection to the server device 1 (the first server). In the case where the network communication status of the first server is in a non-connectable state, it establishes a data communication with the server device 2 (the second server), sends a query message to the server device 2, and performs a data retrieval through the retrieval unit of the server device 2. If the retrieval is successful, it receives the medical image file containing the medical image or the medical image address returned by the transmission unit of the server device 2.

[0096] In the technical solution of the embodiment of the present application, in the case where the network communication status of the first server is in a non-connectable state, by sending a second query message to the second server and receiving the retrieved medical image data, it is possible to query the stored medical image data in real time, improving the stability and availability of the storage of medical image data.

[0097] Figure 7 The figure shows a schematic diagram of a distributed storage query system for medical image data according to an embodiment of the present application.

[0098] The embodiment of the present application provides a distributed storage query system 700 for medical image data. The system includes multiple servers, such as the first server 710, the second server 720, the third server 730, ……, and each server can execute the method of any of the above embodiments.
