Description

Technical Field

[0001] The present application relates to the field of data processing, and in particular, to a method, system, storage medium and computer program product for managing reconstruction tasks of positron emission tomography. Background Art

[0002] Positron emission tomography (PET) is one of the most advanced molecular imaging technologies currently available. It reconstructs images by detecting coincident events corresponding to the annihilation of positrons and electrons in the object being measured.

[0003] There are generally two major steps from PET scanning to obtaining images, namely data collection and image reconstruction. The detector scans the object to be tested to collect data, and reconstructs the data according to different protocol parameters to obtain an image. Traditional PET reconstruction uses a single-task reconstruction mode. In this mode, the server receives reconstruction tasks continuously. During this process, it does not pay attention to whether the reconstruction task currently processed by the server has been completed. At this time, it is very easy to have task stacking problems, that is, a new reconstruction task arrives before the current reconstruction task is completed, which will often cause the later reconstruction task to be lost. In addition, since the reconstruction parameters are not stored during the sending process of the reconstruction task in the single-task mode, the reconstruction parameters may also be lost. These will eventually lead to reconstruction failure. Once data is lost or reconstruction fails, it will have a serious impact on patients, hospitals and equipment manufacturers. For example, patients will have to be re-tested, which increases the risk of radiation, and the reputation of hospitals and equipment manufacturers will be damaged.

[0024] As described in the previous background technology, in the image reconstruction process of positron emission computed tomography technology, there is a problem of reconstruction task failure due to unreasonable reconstruction task management. To address this problem, the present application provides a reconstruction task management method for positron emission computed tomography.

[0025] Some preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes and is not intended to limit the scope of protection of the present application.

[0026] Figure 1 FIG. 1 is a schematic flow chart of a method for managing reconstruction tasks of positron emission tomography according to an embodiment of the present application. Figure 1 As shown, the reconstruction task management method provided in the embodiment of the present application generally includes: S10: receiving and storing the reconstruction task, and forwarding the reconstruction task to the reconstruction server according to a preset rule; S20: Receive a reconstruction result obtained by the reconstruction server from processing the reconstruction task, and forward the reconstruction result to the client.

[0027] The preset rule may be set based on experience, and the preset rule is based on the premise that no reconstruction task stacking occurs.

[0028] The reconstruction task originates from the client, and the reconstruction server performs image reconstruction according to the reconstruction task to obtain the reconstruction result, wherein the reconstruction result includes information on whether the reconstruction is successful, and when the reconstruction is successful, also includes a reconstructed image. The reconstruction server may use an existing algorithm to perform image reconstruction, and the reconstruction algorithm may be any one of the prior art, which is not claimed for protection by this application, and therefore, will not be described in detail.

[0029] The reconstruction task includes: at least one of task type, object information, reconstruction protocol parameters, scan protocol parameters, examination bed information, scan sequence number and image sequence number.

[0030] The task type is one of running and terminating.

[0031] The test subject information includes at least one of age, gender, and radionuclide medication information.

[0032] The reconstruction protocol parameters include: reconstruction algorithm selection and parameters required by the algorithm.

[0033] The scanning protocol parameters include: at least one of scanning time, scanning length, scanning bed position and scanning field of view.

[0034] The radionuclide medication information includes at least one of the type of radionuclide, injection volume, residual volume, scanning time and medication time.

[0035] Figure 2 The following is a schematic flow chart of the specific steps of the reconstruction task management method for positron emission tomography provided in accordance with an embodiment of the present application. Figure 2As shown, in an example of the present application, forwarding the reconstruction task to the reconstruction server according to a preset rule includes: S11: forwarding the reconstruction tasks in sequence according to the time sequence in which the reconstruction tasks are received, and forwarding a subsequent reconstruction task only when a reconstruction result corresponding to a previous reconstruction task is received as successful.

[0036] Figure 3 FIG. 1 is a first specific example diagram of a method for managing reconstruction tasks of positron emission tomography provided in accordance with an embodiment of the present application. Figure 3 , showing that reconstruction tasks are sent to the reconstruction server in sequence, and when the reconstruction result of the previous reconstruction task (reconstruction task 1) is successful, the next reconstruction task (reconstruction task 2) is sent.

[0037] In this way, by adopting the method of forwarding one by one, the problem of reconstruction task loss caused by sending the next reconstruction task before the previous reconstruction task is completed can be avoided.

[0038] Specifically, see Figure 2 In one example of the present application, forwarding the reconstruction task to the reconstruction server according to a preset rule includes: S12: Forwarding the reconstruction tasks in sequence according to the time sequence in which the reconstruction tasks are received, and when the reconstruction result corresponding to the current reconstruction task is received as failure, re-forwarding the current reconstruction task.

[0039] Figure 4 FIG. 2 is a second specific example diagram of the electron emission tomography reconstruction task management method provided according to an embodiment of the present application. Figure 4 , showing that reconstruction tasks are sent to the reconstruction server in sequence, and when the reconstruction result of reconstruction task 1 is failure, reconstruction task 1 is sent again.

[0040] This ensures that the reconstruction of all tasks can be completed smoothly.

[0041] Specifically, in an example of the present application, the receiving and storing the reconstruction task, and forwarding the reconstruction task to the reconstruction server according to a preset rule, includes: S13: Arrange all reconstruction tasks according to the received time sequence, skip any reconstruction task according to the reconstruction instruction, and forward the reconstruction task following the skipped reconstruction task.

[0042] In some cases, a reconstruction task may be repeated or invalid. In this case, there is no need to rebuild the task again. The client will generate a reconstruction instruction to skip the reconstruction task. The reconstruction task will be skipped according to the reconstruction instruction to avoid invalid reconstruction process and reduce system load.

[0043] Figure 5 FIG. 3 is a third specific example diagram of the electron emission tomography reconstruction task management method provided according to an embodiment of the present application. Figure 5 , showing that reconstruction task 2 is skipped according to the reconstruction instruction sent by the client, and reconstruction task 3 is directly performed after reconstruction task 1 is completed.

[0044] Specifically, in an example of the present application, the receiving and storing the reconstruction task, and forwarding the reconstruction task to the reconstruction server according to a preset rule, includes: S14: Arrange all reconstruction tasks according to the received time sequence, swap the arrangement sequence of any two or more reconstruction tasks according to the reconstruction instruction, and forward the reconstruction tasks according to the swapped sequence.

[0045] In some cases, although the reconstruction tasks are sorted in the order in which they are received, there are situations where the order in which some reconstruction tasks are issued does not correspond to the order in which they are received due to signal delays or other reasons. To ensure the accuracy of the reconstructed image, reconstruction needs to be performed in the order in which the client issues the reconstruction tasks. Therefore, the order of the reconstruction tasks needs to be swapped.

[0046] Figure 6 FIG. 4 is a fourth specific example diagram of the electron emission tomography reconstruction task management method provided according to an embodiment of the present application. Figure 6 , shows the situation where reconstruction task 2 and reconstruction task 3 are swapped according to the reconstruction instruction. After reconstruction task 1 is completed, reconstruction task 3 is performed first, and then reconstruction task 2 is performed.

[0047] The reconstruction task management method for positron emission tomography provided in the present application stores the reconstruction tasks sent by the client and forwards them according to preset rules, which can solve the problems of data loss and task reconstruction failure caused by reconstruction task stacking in the prior art and ensure the smooth progress of the image reconstruction process. Furthermore, by swapping the order of reconstruction tasks and skipping certain reconstruction tasks, the management of reconstruction tasks can be further optimized, the amount of data processed by the system can be reduced, and the actual reconstruction needs can be met.

[0048] Corresponding to the above-mentioned reconstruction task management method, the present application also provides a reconstruction task management system for positron emission tomography. Figure 7 FIG. 4 is a framework diagram of a reconstruction task management system for electron emission tomography according to an embodiment of the present application. Figure 7As shown, the reconstruction task management system 100 provided by the present application generally includes: a reconstruction task receiver, a reconstruction task forwarder, a reconstruction result receiver and a reconstruction result forwarder. The reconstruction task receiver is used to receive and store the reconstruction task sent by the client 200. The reconstruction task forwarder is used to forward the reconstruction task to the reconstruction server 300 according to a preset rule. Among them, the preset rule can be set based on experience, and the preset rule is based on the premise that no reconstruction task stacking occurs. The reconstruction result receiver is used to receive the reconstruction result sent by the reconstruction server 300. The reconstruction result forwarder is used to forward the reconstruction result to the client 200. Among them, the reconstruction task comes from the client 200, and the reconstruction server 300 performs image reconstruction according to the reconstruction task to obtain the reconstruction result, and the reconstruction result includes information on whether the reconstruction is successful, and when the reconstruction is successful, it also includes the reconstructed image. The reconstruction server 300 can use an existing algorithm to reconstruct the image, and the reconstruction algorithm can be any one of the prior art, which is not claimed by the present application, and therefore, it will not be repeated.

[0049] The reconstruction task includes: at least one of task type, object information, reconstruction protocol parameters, scan protocol parameters, examination bed information, scan sequence number and image sequence number.

[0050] The task type is one of running and terminating.

[0051] The test subject information includes at least one of age, gender, and radionuclide medication information.

[0052] The reconstruction protocol parameters include: reconstruction algorithm selection and parameters required by the algorithm.

[0053] The scanning protocol parameters include: at least one of scanning time, scanning length, scanning bed position and scanning field of view.

[0054] The radionuclide medication information includes at least one of the type of radionuclide, injection volume, residual volume, scanning time, and medication time.

[0055] Specifically, in an example of the present application, the reconstruction task forwarder forwards the reconstruction tasks in sequence according to the time sequence in which the reconstruction tasks are received, and forwards the next reconstruction task only when the reconstruction result receiver receives that the reconstruction result corresponding to the previous reconstruction task is successful. In this way, the one-by-one forwarding method can avoid the problem of reconstruction task loss caused by sending the next reconstruction task before the previous reconstruction task is completed.

[0056] Specifically, in an example of the present application, the reconstruction task forwarder forwards the reconstruction tasks in sequence according to the time sequence in which the reconstruction tasks are received, and when the reconstruction result receiver receives that the reconstruction result corresponding to the current reconstruction task is a failure, it re-forwards the current reconstruction task. In this way, it can be ensured that the reconstruction of all tasks can be successfully completed.

[0057] Specifically, in an example of the present application, the reconstruction task receiver arranges all reconstruction tasks in the order of time received, and the reconstruction task forwarder skips any reconstruction task according to the reconstruction instruction sent by the client 200, and forwards the reconstruction task after the skipped reconstruction task. In some cases, there may be a situation where a reconstruction task is repeated or invalid, and in this case, there is no need to reconstruct the reconstruction task. The client 200 will generate a reconstruction instruction to instruct to skip the reconstruction task, and skip the reconstruction task according to the reconstruction instruction to avoid an invalid reconstruction process and reduce the system load.

[0058] Specifically, in an example of the present application, the reconstruction task receiver arranges all reconstruction tasks in the order of time received, and the reconstruction task forwarder swaps the order of arrangement of any two or more reconstruction tasks according to the reconstruction instruction sent by the client, and forwards the reconstruction tasks in the swapped order. In some cases, although the reconstruction tasks are sorted in the order of time received, there are cases where the order in which some reconstruction tasks are issued does not correspond to the order in which they are received due to signal delay or other reasons. In order to ensure the accuracy of the reconstructed image, it is necessary to reconstruct in the order in which the reconstruction tasks are issued by the client, and therefore, the order of the reconstruction tasks needs to be swapped.

[0059] Specifically, in one example of the present application, see Figure 7 The reconstruction task management system 100 is integrated on a computer and runs independently in the form of an application program. The application program can be arranged on the same host or on other hosts that can communicate over the network. The reconstruction task management system 100 communicates with the main program of the client 200 through an internal network and communicates with the server 300 through an external network.

[0060] Figure 8 FIG. 4 is another framework diagram of a reconstruction task management system for electron emission tomography according to an embodiment of the present application. Figure 8 As shown, in an example of the present application, the reconstruction task management system 100 is integrated in the client 200 and called in the form of a dynamic library. The dynamic library is a storage method for an application code library, which is called during program execution, dynamically linked to the memory, and separated from the main program of the client.

[0061] The reconstruction task management system 100 for positron emission computed tomography provided by the present application stores the reconstruction tasks sent by the client and forwards them according to preset rules, which can solve the problems of data loss and task reconstruction failure caused by reconstruction task stacking in the prior art. Furthermore, by changing the order of reconstruction tasks and skipping certain reconstruction tasks, the management of reconstruction tasks can be further optimized, the amount of data processed by the system can be reduced, and the actual reconstruction needs can be met.
