Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Before the technical scheme of the invention is introduced, a plurality of proper nouns are introduced.
Image Archiving and Communication Systems (PACS) are Systems applied to hospital image departments, and the main task is to store various daily medical images (including images generated by equipment such as nuclear magnetism, CT, ultrasound, various X-ray machines, various infrared instruments, microscopes and the like) in a digital manner through various interfaces (analog, DICOM and network). It has important roles in transmitting data and organizing and storing data among various image devices.
A Radiology Information management System (RIS) is one of the important medical imaging Information systems in hospitals, and together with a PACS System, it forms an Information environment for medical imaging. The radiology department information system is a computer information system for managing task execution processes based on the working process of a hospital imaging department, mainly realizes computer networking control and management of the medical imaging examination working process and sharing of medical image-text information, and realizes remote medical treatment on the basis.
Digital Imaging and Communications in Medicine (DICOM) is an international standard for medical images and related information (ISO 12052). It defines a medical image format that can be used for data exchange with a quality that meets clinical needs. [
DICOM is widely used in radiomedicine, cardiovascular imaging and radiodiagnosis (X-ray, CT, nuclear magnetic resonance, ultrasound, etc.) and is increasingly used in ophthalmology, dentistry, and other medical fields. DICOM is one of the most widely deployed standards for medical information among the tens of thousands of in-use medical imaging devices. There are currently about billions of medical images that comply with the DICOM standard for clinical use.
At present, electronic systems in hospitals are generally equipped with a PACS system and a RIS system. When a patient needs to be examined (for example, a CT examination, a magnetic resonance examination, etc.) after registration, the PACS system acquires image information (for example, CT scan results, magnetic resonance examination results, etc.) of the patient based on patient information (acquired at the time of registration, for example, information such as patient name, identification number, sex, etc.) of the patient, and stores the patient information and the image information of the patient. After the patient is examined, the RIS system acquires corresponding image information from the PACS system according to the patient information of the patient, displays the image information to a doctor, and stores diagnosis information made by the doctor, the patient information and the image information after the doctor makes a diagnosis according to the image information. Therefore, the PACS system stores only patient information and image information, and the RIS system stores three kinds of information, i.e., patient information, image information, and diagnostic information. In the PACS system, data is stored in a specific format, DICOM format, and in the RIS system, data is stored in a structured data format (format that can be understood as data stored in a database).
Based on this, the embodiment of the invention provides a data transmission method, which is used for transmitting data of different formats in two systems of a hospital to a PACS system and an RIS system of the hospital, and transmitting the data to a storage server so that the storage server can store the two data, thereby eliminating data space isolation caused by that each hospital only stores respective data, and reducing the hardware cost for storing data in the hospital. Specifically, the method provided by the embodiment of the invention comprises the following steps:
an embodiment of the present invention provides a data transmission method, which is applied to a front node, where the front node is connected to a user node through a first network, the user node is provided with a first system and a second system, and the front node is further connected to a storage server through a second network, as shown in fig. 1, the method includes:
step 101: respectively acquiring first data in a first system and second data in a second system; the format of the first data is DICOM format, and the format of the second data is structured data format;
step 102: analyzing the first data to obtain third data;
step 103: respectively carrying out encryption and signature adding processing on the second data and the third data to obtain fourth data and fifth data;
step 104: and sending the fourth data and the fifth data to a storage server for storage.
In particular, the first system may be a PACS system and the second system may be a RIS system. The front-end node can be a front-end processor, the user node can be a hospital equipment end, the first network can be an internal network of a hospital, and the second network can be a configured private network for sanitation. The first network and the second network are independent networks. In practical application, the front-end processor is connected with the hospital equipment end through the internal network of the hospital, the hospital equipment end is provided with the PACS system and the RIS system, and meanwhile, the front-end processor can be connected with the storage server through the private health network.
In actual use, because the first network and the second network are mutually independent networks, in order to smoothly realize the transmission of data in the two independent networks, the front node can store the first data and the second data in the local storage position of the front node through the first network in a ground mode, then process the first data and the second data in the local storage position, and after the processing is finished, send the processed fourth data and the processed fifth data to the storage server through the second network.
Here, in order to avoid the loss of the first data and the second data during the transmission process, the first data and the second data may be backed up after the first data and the second data are saved in the local storage location, and the backed-up data may be saved.
Meanwhile, in order to realize effective management of data transmission and avoid data loss, a designated directory can be set in the local storage location, and only the first data and the second data are stored in the set designated directory.
In addition, because the front node acquires the first data from the PACS system and the second data from the RIS system, the front node can acquire the first data and the second data from the PACS system and the RIS system respectively in different modes aiming at two different systems. Specifically, in an embodiment, the first data may be obtained by receiving the first data actively pushed by the PACS system. In another embodiment, the second data in the RIS system may be actively acquired by using Java Database Connectivity (JDBC).
JDBC is an application program interface in the Java language that is used to specify how a client program accesses a database, providing methods such as querying and updating data in the database. JDBC is generally a relational database-oriented data acquisition approach.
Because the format of the first data is the DICOM format and the format of the second data is the structured data format, the first data needs to be analyzed and processed first in the data transmission process to obtain third data; after the analysis processing, the second data and the third data are respectively encrypted and signed to obtain fourth data and fifth data; and sending the fourth data and the fifth data to a storage server.
Specifically, in an embodiment, the parsing the first data to obtain third data includes:
analyzing the first data to obtain structured information;
generating third data according to the structured information; and the format of the third data is a structured data format.
Here, the structured information may be obtained in a conventional processing manner for processing DICOM data. There are many processing methods for processing DICOM data, which are common technical means and are not described herein again.
Further, the structured information may include information such as the inspection Uid, dicomid, and the like.
In addition, after the second data and the third data are obtained, the second data and the third data can be processed to obtain data with a uniform format, so that the second data and the third data can be encrypted and signed respectively in a uniform mode. Specifically, after the second data and the third data are obtained, the second data and the third data may be generated into corresponding xxx.dat data files according to a JSON format, and then the generated xxx.dat data files are encrypted and signed.
Here, the encryption and tagging processing may adopt a common encryption and tagging means, which is not described herein again.
Further, after the encryption and the signing are completed, the fourth data and the fifth data obtained after the encryption and the signing are processed can be sent in a batch sending mode.
In an embodiment, sending the fourth data and the fifth data to a storage server for storage includes:
generating batch data according to a preset rule by using the fourth data and the fifth data;
and sending the batch data to a storage server in batches for storage.
In practice, the preset rule may be set to generate the batch data in time, for example, one batch data every 5 minutes, or one batch data every 10 minutes. The preset rule may also be set to generate the batch data by the number of pieces, for example, one batch data per 1 thousand pieces, or one batch data per 3 thousand pieces.
In addition, in order to better save the data, the first data may be sent to the storage server for storage. Meanwhile, for security, the first data may be transmitted to the storage server for storage through a specific DICOM data transmission channel.
The data transmission method provided by the embodiment of the invention respectively acquires first data in a PACS system and second data in an RIS system; the format of the first data is a medical digital imaging and communication format, and the format of the second data is a structured data format; analyzing the first data to obtain third data; respectively carrying out encryption and signature adding processing on the second data and the third data to obtain fourth data and fifth data; sending the fourth data and the fifth data to a storage server for storage; and after the storage server obtains the fourth data and the fifth data, the fourth data and the fifth data are decrypted and checked, and the second data and the third data obtained after processing are stored. According to the scheme of the embodiment of the invention, the data in the two systems at the hospital end can be stored in the storage server, the data space isolation caused by only storing the data of each hospital is eliminated, meanwhile, the data at the hospital end is stored in the storage server, the data does not need to be stored at the hospital end, and the hardware cost for storing the data at the hospital end is reduced.
An embodiment of the present invention further provides another data transmission method, which is applied to a storage server, where the storage server is connected to a front node through a second network, the front node is connected to a user node through a first network, and the user node is provided with a first system and a second system, as shown in fig. 2, the method includes:
step 201: receiving fourth data and fifth data sent by the front node; the fourth data is obtained after the preposed node encrypts and signs the second data from the second system, the fifth data is obtained after the preposed node encrypts and signs the third data respectively, and the third data is obtained after the preposed node analyzes and processes the first data from the first system; the format of the first data is DICOM format, and the format of the second data is structured data format;
step 202: decrypting and checking the fourth data and the fifth data respectively to obtain second data and third data;
step 203: and storing the second data and the third data.
In particular, the first system may be a PACS system and the second system may be a RIS system. The front-end node can be a front-end processor, the user node can be a hospital equipment end, the first network can be an internal network of a hospital, and the second network can be a configured private network for sanitation. The first network and the second network are independent networks. In practical application, the front-end processor is connected with the hospital equipment end through the internal network of the hospital, the hospital equipment end is provided with the PACS system and the RIS system, and meanwhile, the front-end processor can be connected with the storage server through the private health network.
Here, the first network and the second network are two networks independent of each other.
When the storage server stores the second data and the third data, the second data and the third data can be directly stored in a local node where the storage server is located, or can be stored in a remote database.
Specifically, when the second data and the third data are stored in the remote database, the second data and the third data may be first stored in a local node where the storage server is located, and then the second data and the third data are stored in the remote database from the local node.
Message middleware may be utilized in storing the second data and the third data from the local node to the remote database. Specifically, after the second data and the third data are stored in the local node, the first component sends a push success message to the message middleware, and after finding that the push success message exists, the second component having a subscription relationship with the message middleware acquires the second data and the third data from the local node and stores the second data and the third data in the remote database. Here, the message middleware may use Kafka, ActiveMQ, RabbitMQ, RocktMQ, ZeroMQ, etc.
Storing the second data and the third data in a remote database, which can be stored in the following way:
in one embodiment, storing the second data and the third data comprises:
analyzing the second data and the third data respectively to obtain analyzed data;
and writing the analyzed data into the remote database according to the preset format of the remote database for storage.
Specifically, the second data and the third data may be analyzed by extracting a character string, so as to obtain analysis data.
Further, in order to avoid duplication of data stored in the database, the data in the remote database may be deduplicated and the processed data may be stored in the second database. Specifically, the deduplication process may be performed by way of ETL data cleansing.
Here, the remote database may be specifically a database ODS layer, and the second database may be specifically a data warehouse DW layer.
In addition, in order to further improve the data saving effect and prevent the data loss, in an embodiment, after the storing the second data and the third data, the method further includes:
performing association matching on the second data and the third data;
judging whether the second data or the third data has data which is not successfully matched, and acquiring the data which is not successfully matched;
determining difference data according to the data which is not successfully matched;
based on the difference data, a difference data acquisition request is sent to the front node to cause the front node to send the difference data.
Specifically, the second data and the third data may be subjected to correlation matching at regular time. For example, 24 points per day may be set to perform association matching on the data of the previous day. In addition, in the matching, the matching may be performed by checking the related information, for example, by checking the patient visit number.
The data transmission method provided by the embodiment of the invention respectively acquires first data in a PACS system and second data in an RIS system; the format of the first data is a medical digital imaging and communication format, and the format of the second data is a structured data format; analyzing the first data to obtain third data; respectively carrying out encryption and signature adding processing on the second data and the third data to obtain fourth data and fifth data; sending the fourth data and the fifth data to a storage server for storage; and after the storage server obtains the fourth data and the fifth data, the fourth data and the fifth data are decrypted and checked, and the second data and the third data obtained after processing are stored. According to the scheme of the embodiment of the invention, the data in the two systems at the hospital end can be stored in the storage server, the data space isolation caused by only storing the data of each hospital is eliminated, meanwhile, the data at the hospital end is stored in the storage server, the data does not need to be stored at the hospital end, and the hardware cost for storing the data at the hospital end is reduced.

In addition, the front-end processor is also provided with an RIS acquisition service and a PACS acquisition service (also called image acquisition service), wherein the image acquisition service is the most basic module for regional image retrieval, and comprises image examination report acquisition, DICOM image file acquisition and image quality control data acquisition; the convergence of image related data is realized; after the image acquisition service finishes acquisition, the object storage service (also called data storage service) realizes the storage of image data in the cloud, and archives the image file by analyzing the DICOM image file.
Specifically, referring to fig. 4, the data transmission process includes the following steps:
1) the image acquisition service receives DICOM files actively pushed by a PACS system at a hospital end and stores the DICOM files in a specified directory of the front-end processor.
2) The data transmission service scans the directory of the image stored by the front-end processor, and when finding a file, the DICOM file is moved to the temporary storage directory to prevent the file from being scanned repeatedly; and meanwhile, the file is copied and backed up, so that uploading failure is prevented.
In the process, the data transmission service analyzes the DICOM file, obtains structural information such as Uid and dicoid in the DICOM file, and generates a xxx. Dat data files are signed encrypted after being generated.
Meanwhile, the RIS collection service is connected with a database view of a hospital-side RIS system in a JDBC mode to obtain RIS report data, and xxx. Likewise, the xxx. Dat data files are signed encrypted after being generated.
Here, the encryption method may be performed by using the cryptographic algorithm SM 2.
In addition, the data files may be generated in time batches. For example 5 minutes for one batch.
Here, the time interval can be dynamically configured according to actual service requirements, and the data transmission time lag is reduced.
In particular, the xxx.dat data file may be in the format: dicom _ tag _20210309164.dat exam _20210309164. dat.
3) The data transmission service uploads the DICOM file stored on the front-end processor to an object storage (which can be understood as a storage node of an image cloud center).
In this process, the data transmission service uploads the written batch data file to the object storage, and the upload is successful in sending a push success message to a message processing tool (e.g., Kafka, etc.).
4) The data storage service subscribes to messages of a message processing tool (such as Kafka) and extracts data files from the object storage when finding successful messages, analyzes the files, and records the analyzed data into a big data platform-database ODS layer to realize data landing.
5) And the ODS layer data enters a DW layer of a big data platform-data warehouse through ETL data cleaning.
6) And the data checking correlation service checks and correlates the RIS report data and the DICOM image data according to the day at regular time, and counts the difference.
7) If the data are found to be different in missing, initiating a request for pushing the image again to the hospital end through Q/R retransmission compensation service; and the RIS pulls the report of the designated RIS again according to the designated parameters, so that a data compensation mechanism is realized.
Here, Q/R is Query/Retrieve. Query refers to a request that the opposite system transmits information requesting a certain level (parent/Study/Series/Image) to itself. Of course, the correlation query can be performed to require the other party to return the information of each level to the other party. The Retrieve means that the SCU requests the other party to send an Image to the other party according to the request level (parent/student/Series/Image) after the SCU takes information through the Query.
The architecture provided by the application embodiment realizes data storage from a hospital to a cloud end, breaks the space isolation of the traditional hospital medical image system, has practicability and is feasible through practice verification.
