Description

[0002] Based on the image reconstruction link, raw data obtained by scanning of a medical device can be processed to generate high-quality medical images. In traditional techniques, the image reconstruction link uses a pipeline mechanism for data transmission. Assuming that the image reconstruction link involves a raw data reading node, a filtering node, an interpolation node, and an image reconstruction node, the raw data reading node obtains part of the raw data from the medical device, sends the part of the raw data to the filtering node, the filtering node performs filtering processing on the part of the raw data, sends the processed data to the interpolation node, the interpolation node further performs interpolation processing on the data processed by the filtering, and sends the interpolation-processed data to the image reconstruction node, so that the image reconstruction node performs image reconstruction based on the interpolation-processed data to obtain a medical image.

[0003] In the existing data transmission process in the image reconstruction link, whether the previous node continues to execute depends on whether the subsequent node completes data processing. For example, the raw data reading node can send the newly read part of the raw data to the filtering node only after the filtering node performs filtering processing on the part of the raw data and sends the processed data to the interpolation node.

[0041] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0042] In the conventional technology, the image reconstruction link adopts a pipeline mechanism for data transmission. The pipeline mechanism submits tasks by taking a Job (task node) as a task unit, and a configuration file of the Job defines master and slave process nodes. The Job is managed (state) by the Job as a resident process through a Job queue and a message queue.

[0043] The pipeline mechanism as a whole is managed by a configuration file and code. The data processing logic of different task nodes is different. Especially under the demand of large-scale data transmission and high-performance reconstruction, the data blocking mode will cause computer memory overflow and other problems, affecting the robustness of the image reconstruction link. In addition, the pipeline mechanism needs to store the acquired raw data into the computer device 1, and the raw data reading node reads part of the stored raw data from the computer device 1. However, in the process of storing the acquired raw data into the computer device 1 and reading part of the stored raw data from the computer device 1, the computer device 1 is prone to damage, so a backup is made by storing the acquired raw data into the computer device 2. Therefore, for the redundant design considering the machine damage of the computer device in the distributed peripheral scenario, the overall system monitoring and scheduling complexity will increase sharply. In order to solve the above technical problems, the present application provides a data transmission method, device and equipment in an image reconstruction link and a storage medium.

[0044] The data transmission method in the image reconstruction link provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 The application environment includes a computer device, which can be a server, and its internal structure diagram can be as shown in Figure 1As shown in the figure. The computer device includes a processor, a memory, an input / output interface (Input / Output, referred to as I / O) and a communication interface. Among them, the processor, the memory and the input / output interface are connected through the system bus, and the communication interface is connected to the system bus through the input / output interface. Among them, the processor of the computer device is used to provide computing and control capability. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used to store the related data of data transmission. The input / output interface of the computer device is used to exchange information between the processor and external devices. The communication interface of the computer device is used to communicate with external terminals through network connection. The computer program is executed by the processor to realize a data transmission method in an image reconstruction link. The server can be realized by an independent server or a server cluster composed of multiple servers.

[0045] In an exemplary embodiment, as Figure 2 shown, a data transmission method in an image reconstruction link is provided. The method is applied to the computer device in Figure 1 for example, including the following S201 to S202. Among them:

[0046] S201, reading first data according to identification information of the first data stored in the global data space; the first data is the raw data of the scanning object written by the medical device or the data written by the previous task node of the target task node.

[0047] Among them, the identification information is a way to uniquely identify and identify the first data, which is of great significance to the management and application of the first data. Since the target task node reads the first data according to the identification information, it is not necessary to manage the first data according to the writing order of the previous task node of the target task node, that is, it is not necessary to manage the first data through the message queue, realizing the separation of time and first data space.

[0048] The target task node can read the first data from the global data space based on the identification information according to its own needs when reading data.

[0049] In this embodiment, a global data space is set in the image reconstruction link, which can be realized based on data distribution service (Data Distribution Service, DDS), as Figure 3As shown, the DDS is a data topic-centered publish-subscribe model, a data-centered intermediate protocol and API standard, and a user only cares about the data he wants.

[0050] The global data space is a local storage space created in a logical concept, i.e., the first data written into the global data space is shared data, the first data can be in the form of a topic, and the first data with identification information is written into the global data space for data transmission, so as to realize the data-centered intermediate protocol and API standard. The task node includes multiple task nodes, which can be set according to actual conditions and are scalable and adaptive to data processing.

[0051] The target task node reads the first data from the global data space according to the identification information, for example, the image reconstruction link includes task node 1, task node 2, task node 3 and task node 4, if the target task node is task node 1, the first data is raw data, and task node 1 reads the raw data from the global data space according to the identification information of the raw data; if the target task node is task node 2 / task node 3 / task node 4, the first data is the data written by the previous task node of the target task node.

[0052] Optionally, the multiple task nodes can be deployed on one computer device or multiple computer devices.

[0053] S202, processing the first data according to the task type of the target task node to obtain second data.

[0054] In this embodiment, the task type can be reading encapsulation, filtering processing, image reconstruction, etc. After obtaining the first data, the target task node processes the first data according to the task type of the target task node to obtain second data.

[0055] Since the method proposed in the present application is to write raw data into the global data space, the phenomenon of redundant design of computer devices in the distributed peripheral scene in the traditional technology, such as machine damage, is solved.

[0056] In the data transmission method in the image reconstruction link, the first data is read according to the identification information of the first data stored in the global data space, and the first data is processed according to the task type of the target task node to obtain second data; the first data is the raw data of a scanning object written by a medical device or the data written by a previous task node of the target task node. In the embodiment of the application, since the global data space is provided, the previous task node of the target task node can write the processed data into the global data space, and the target task node only needs to read the first data from the global data space according to the identification information, which is data-centered, has high throughput, and has good real-time data transmission, so that the acquisition of the raw data and the image reconstruction based on the raw data can be processed in real time in parallel, the raw data does not need to be stored on the premise of safety and reliability of the raw data, and is directly used for subsequent reading and reconstruction, thereby improving the efficiency of data transmission in the image reconstruction link.

[0057] In one embodiment, the data transmission method in the image reconstruction link further includes: writing the second data into the global data space.

[0058] In the embodiment, after obtaining the second data, the target task node can mark the second data to obtain second data with identification information, and write the second data with identification information into the global data space.

[0059] In one possible implementation, the storage space in the global data space can also be identified to obtain a plurality of sub-data spaces, and the second data can be placed in the corresponding identified sub-data space.

[0060] In the embodiment of the application, the second data is written into the global data space, which lays a foundation for the next task node of the target task node to read the second data from the global data space, and improves the efficiency of data transmission.

[0061] Figure 4 For a flowchart of the second data writing method in one embodiment, as shown in Figure 4 The embodiment of the application relates to one possible implementation of how to write the second data into the global data space, and includes the following steps:

[0062] S401, marking the second data to obtain second data with identification information.

[0063] In the embodiment, the second data can be identified by using identification methods such as digital fingerprints, data labels, metadata, data indexes, and data standards to obtain second data with identification information.

[0064] S402, writing the second data with identification information into the global data space.

[0065] In the embodiment, the target task node can directly write the second data with the identification information into the global data space, or write the second data with the identification information into the global data space based on the service quality policy of the second data with the identification information.

[0066] Further, the writing of the second data with the identification information into the global data space comprises: writing the second data with the identification information into the global data space based on the service quality policy of the second data with the identification information.

[0067] By setting the service quality policy of the second data, the writing and reading of the second data can be configured specifically. The service quality policy can comprise reliability: determining the reliability requirement of the transmission of the second data, and can select to use a reliable transmission mechanism to ensure the integrity and order of the second data, or use an unreliable transmission mechanism to allow the loss or disorder of the second data; persistence: determining whether the computer device should retain the persistent storage of the second data. If the persistence is enabled, the second data can be saved on the disk to recover the data after the computer device is restarted; lifetime: defining the valid time of the data in the image reconstruction link, and a time limit can be set, and when the second data exceeds the time limit, the second data will no longer be transmitted in the image reconstruction link.

[0068] In the embodiment, the second data is marked to obtain the second data with the identification information, and the second data with the identification information is written into the global data space based on the service quality policy of the second data with the identification information. In the embodiment, the transmission mode of the theme data can be configured according to specific requirements and system requirements by the service quality policy to meet the requirements of real-time, reliability and efficiency.

[0069] In one embodiment, the reading of the first data according to the identification information of the first data stored in the global data space comprises: reading the first data according to the identification information of the first data stored in the global data space based on the service quality policy of the first data.

[0070] In the embodiment, the service quality policy of the first data can be the same as the service quality policy of the second data, or the service quality policy of the first data can be different from the service quality policy of the second data.

[0071] In one embodiment, the reading of the first data according to the identification information of the first data stored in the global data space comprises: in the case that the target task node is a live data reading node, if an execution command sent by the host is received, the first data is read according to the identification information of the first data stored in the global data space.

[0072] In the embodiment, as Figure 5As shown, a master process (command line program) is deployed on the host, and a slave process is deployed on the slave. In the case where the target task node is a raw data reading node, upon receiving an execution command sent by the host, the first data is read from the global data space according to the identification information.

[0073] The raw data reading node processes the raw data with the identification information to obtain data 1, identifies the data 1 to obtain data 1 with the identification information, writes the data 1 with the identification information into the global data space, the preprocessing node reads the data 1 with the identification information from the global data space, processes the data 1 with the identification information to obtain data 2, identifies the data 2 to obtain data 2 with the identification information, and writes the data 2 with the identification information into the global data space. The image reconstruction node reads the data 2 with the identification information from the global data space.

[0074] Optionally, after the medical device obtains the raw data, the raw data can also be stored for backup.

[0075] In the embodiments of the present application, in the case where the target task node is a raw data reading node, if an execution command sent by the host is received, the first data is read according to the identification information of the first data stored in the global data space, and the intelligence of data transmission is improved.
