[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0054] The imaging method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The computer device in the application environment can be a server, a personal computer, a laptop computer, a smart phone, a tablet computer, a smart mobile phone, etc. The computer device may include a processor, a memory and a network interface connected via a system bus or wirelessly. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device may include 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 data in the imaging process. The network interface of the computer device is used to communicate with an external terminal through a network connection, and the computer program is executed by the processor to implement an imaging method.
[0055] In an exemplary embodiment, Figure 2 As shown, an imaging method is provided, which is applied to Figure 1 The computer device in the example is used to illustrate, including the following steps 201 to 202. Among them:
[0056] S201, responding to the fault prompt information on the display interface, in the case that the original data acquisition device has a fault, determining the data to be reconstructed based on the original data acquired by the original data acquisition device and the backup data acquisition device.
[0057] The original data acquisition device and the backup data acquisition device are both devices for collecting original data. The display interface can output fault prompt information in the form of text, voice, or text and voice. The embodiment of the present application does not limit the output form of the fault prompt information.
[0058] In an embodiment of the present application, the original data acquisition device may fail before the original data is acquired. In this case, a backup data acquisition device is required to acquire all the original data, and the original data acquired by the backup data acquisition device is used as the data to be reconstructed.
[0059] The original data acquisition device may also fail during the original data acquisition process, including two different situations. In one case, if the original data acquisition device and the backup data acquisition device start to collect original data of the scanned object at the same time, and the original data acquisition device fails during the acquisition process, then the original data collected by the backup data acquisition device can be directly used as the data to be reconstructed. In another case, during the data acquisition process, if the original data acquisition device first collects separately and fails during the acquisition process, then the backup data acquisition device rescans, or the backup data acquisition device continues to scan the faulty position. If the backup data acquisition device rescans, the original data collected by the backup data acquisition device is used as the data to be reconstructed; if the backup data acquisition device continues to scan, the original data collected by the original data acquisition device and the backup data acquisition device are fused, and the fused data is used as the data to be reconstructed.
[0060] The original data acquisition device may also fail after the original data acquisition is completed, which includes two different situations. In one case, the original data acquisition device collects original data alone, and the data to be reconstructed is the original data collected by the original data acquisition device. In another case, the original data acquisition device and the backup data acquisition device collect original data at the same time, and the data to be reconstructed can be the original data collected by the original data acquisition device or the original data collected by the backup data acquisition device.
[0061] S202, reconstructing the data to be reconstructed by using an original image reconstruction device or a backup image reconstruction device to obtain a reconstructed image.
[0062] In an embodiment of the present application, when the original image reconstruction device does not fail, the computer device can control the original image reconstruction device to reconstruct the data to be reconstructed based on the image reconstruction algorithm to obtain a reconstructed image. When the original image reconstruction device fails before or during reconstruction, the computer device can control the backup image reconstruction device to reconstruct the data to be reconstructed based on the image reconstruction algorithm to obtain a reconstructed image. For example, the image reconstruction algorithm can be a direct back-projection method, an iterative method, an analytical method, or a convolution back-projection method.
[0063] It should be noted that in order to avoid the impact of excessive amount of raw data on the performance and reliability of the computer device, the raw data acquisition device and the raw image reconstruction device can be set to run on different computer devices. Based on this, the backup data acquisition device and the backup image reconstruction device can be set separately on two other computer devices, or the backup data acquisition device and the raw data acquisition device can be set on the same computer device, and the backup image reconstruction device and the raw image reconstruction device can be set on the same computer device.
[0064] Taking the medical imaging device, such as the positron emission computed tomography (PET) device, as an example, it is an imaging detection technology that uses the detection of gamma photons to form images. It is mainly divided into two parts: detecting gamma photon information and reconstructing images based on gamma photon information. The detection and acquisition of gamma photon information requires the detector to collect photon information, which is then converted into a large amount of processable digital information and transmitted to the image reconstruction system. The image reconstruction device then reconstructs the image and finally generates a recognizable PET image. In order to increase the speed of PET acquisition and reconstruction imaging, the acquisition and reconstruction of PET are usually placed on a single computer device, that is, the data acquisition device and the image reconstruction device are respectively set on different computer devices.
[0065] In the above imaging method, in response to the fault prompt information on the display interface, when the original data acquisition device fails, the data to be reconstructed is determined based on the original data collected by the original data acquisition device and the backup data acquisition device; the data to be reconstructed is reconstructed by the original image reconstruction device or the backup image reconstruction device to obtain a reconstructed image. This method sets a backup data acquisition device and a backup image reconstruction device for the imaging process. When the original data acquisition device fails, the cooperation between the original data acquisition device and the backup data acquisition device can avoid the failure of the original data acquisition device to continue data acquisition. In the subsequent reconstruction process, the original image reconstruction device and the backup image reconstruction device also cooperate to reconstruct the image, avoiding the failure of the original image reconstruction device to reconstruct the image. In this way, based on the added backup data acquisition device and the backup image reconstruction device, it can be ensured that the data acquisition and image reconstruction process will not be interrupted, thereby improving the imaging reliability.
[0066] The situation where the original data acquisition device fails before or after data acquisition is completed is relatively simple. Next, two situations where the original data acquisition device fails during the data acquisition process are described in detail.
[0067] In one case, in order to avoid failure of the original data acquisition device during the data acquisition process, the original data acquisition device and the backup data acquisition device can be controlled to acquire data simultaneously. If a failure occurs during the acquisition process, the original data acquired by the backup data acquisition device can be used as the data to be reconstructed. In one embodiment, the specific process of determining the data to be reconstructed based on the original data acquired by the original data acquisition device and the backup data acquisition device includes the following contents:
[0068] When the original data acquisition device and the backup data acquisition device acquire data at the same time and the original data acquisition device fails, the original data acquired by the backup data acquisition device is used as the data to be reconstructed.
[0069] In an embodiment of the present application, a computer device can simultaneously control an original data acquisition device and a backup data acquisition device to acquire original data for the same scanning object, that is, the acquisition time, acquisition object, and acquisition data of the original data acquisition device and the backup data acquisition device are consistent. During the acquisition process, once the original data acquisition device fails, the original data acquisition device cannot continue subsequent data acquisition, and the original data acquired by the original data acquisition device before the failure position is ignored. If the backup data acquisition device continues to acquire original data after the failure position, then the data acquired by the backup data acquisition device is complete original data, and the computer device can use the complete original data acquired by the backup data acquisition device as data to be reconstructed.
[0070] In the above imaging method, when the original data acquisition device and the backup data acquisition device are acquiring data at the same time, and the original data acquisition device has a fault, the original data acquired by the backup data acquisition device is used as the data to be reconstructed. In this method, when two data acquisition devices are acquiring data at the same time, the acquired original data are basically consistent. Then, when one data acquisition device has a fault, the complete original data acquired by the other data acquisition device can be used as the data to be reconstructed, avoiding the need to switch the data acquisition device after the fault occurs, and also avoiding the process of re-acquiring the data before the fault position after the switch, thereby improving the efficiency of data acquisition.
[0071] In another case, the original data acquisition device is first controlled to perform data acquisition alone, and when a failure occurs during the acquisition process, the backup data acquisition device is used to perform data acquisition. Then, in one embodiment, the specific process of determining the data to be reconstructed based on the original data collected by the original data acquisition device and the backup data acquisition device includes the following contents:
[0072] When the original data acquisition device acquires data independently and there is a fault in the original data acquisition device, the data to be reconstructed is determined based on the original data acquired by the original data acquisition device before the fault and the original data acquired by the backup data acquisition device.
[0073] In the embodiment of the present application, since the possibility of failure of the original data acquisition device is small, then each data acquisition process collects the original data through the original data acquisition device and the backup data acquisition device, which will cause a waste of resources. Therefore, the computer device can control the original data acquisition device to collect alone first, and determine whether it fails during the collection process. If no failure occurs, the original data collected by the original data acquisition device is directly used as the data to be reconstructed. If a failure occurs, the backup data acquisition device is controlled to re-collect or continue to collect. In the case of re-collection, the data to be reconstructed is the complete original data collected by the backup data acquisition device. In the case of continued collection, the original data acquisition device collects the original data before the fault position, and the backup data acquisition device collects the original data at the fault position and after the fault position. The original data before the fault position, the original data at the fault position and after the fault position are all used as the data to be reconstructed.
[0074] In the above imaging method, when the original data acquisition device acquires data separately and there is a fault in the original data acquisition device, the data to be reconstructed is determined based on the original data acquired by the original data acquisition device before the fault and the original data acquired by the backup data acquisition device. The method is to first acquire data separately through the original data acquisition device, and after the fault occurs, switch to the backup data acquisition device to acquire the original data, so that the waste of resources caused by acquiring data simultaneously through two data acquisition devices can be avoided, and the reliability of the data acquisition process can also be guaranteed.
[0075] When the original data collection device fails and switches to the backup data collection device for collection, the backup data collection device needs to determine whether to continue collection or completely re-collect. Figure 3 As shown, the specific content of determining the data to be reconstructed based on the original data collected by the original data collection device before the failure and the original data collected by the backup data collection device is introduced, and the specific content includes the following steps:
[0076] S301, testing the original data collected by the original data collection device before the fault location to obtain a test result; the test result indicates whether there is an abnormality in the original data.
[0077] In the embodiment of the present application, when the original data acquisition device fails during the acquisition process, the original data collected before the location where the failure occurs may be inaccurate. Therefore, the computer device can detect the original data collected by the original data acquisition device before the failure location, for example, the integrity and continuity of the original data can be analyzed to determine whether the original data collected before the failure location is abnormal, and obtain the detection result.
[0078] S302, determining data to be reconstructed according to the detection result, the original data collected by the original data collection device before the fault location, and the original data collected by the backup data collection device.
[0079] In an embodiment of the present application, when the detection result indicates that the original data is abnormal, it means that the original data collected by the original data acquisition device before the fault location will affect the subsequent image reconstruction results. At this time, it is necessary to use a backup data acquisition device to collect the original data before, at and after the fault location, and use the collected original data as the data to be reconstructed.
[0080] In the above imaging method, the original data collected by the original data acquisition device before the fault position is detected to obtain a detection result; the detection result indicates whether the original data has an abnormality; the data to be reconstructed is determined based on the detection result, the original data collected by the original data acquisition device before the fault position, and the original data collected by the backup data acquisition device. This method analyzes whether the original data collected before the fault position is abnormal, thereby accurately judging whether the fault has an impact on the data acquisition process, and based on the detection result, the data to be reconstructed can be accurately obtained.
[0081] In one embodiment, Figure 4 As shown, the above-mentioned determination of the specific content of the data to be reconstructed based on the detection results, the original data collected by the original data collection device before the fault location and the original data collected by the backup data collection device includes the following steps:
[0082] S401, if the detection result shows that there is an abnormality, the original data collected by the backup data acquisition device is used as the data to be reconstructed; the original data includes the data collected by the backup data acquisition device before the fault location, the fault location and the data collected after the fault location.
[0083] In the embodiment of the present application, if it is determined that the original data collected before the fault position is abnormal, it means that the fault of the original data acquisition device has an impact on the collected original data, that is, the original data collected before the fault position will affect the subsequent image reconstruction process. In this case, the computer device can control the backup data acquisition device to re-collect the original data before the fault position, and collect the original data at the fault position and after the fault position, and use the re-collected original data before the fault position, the fault position, and the original data after the fault position as the data to be reconstructed.
[0084] S402, if the detection result shows that there is no abnormality, the original data collected by the original data collection device before the fault location and the original data collected by the backup data collection device at the fault location and after the fault location are used as data to be reconstructed.
[0085] In the embodiment of the present application, if it is determined that there is no abnormality in the original data collected before the fault position, it means that the fault of the original data acquisition device has no effect on the collected original data, that is, the original data collected before the fault position will not affect the subsequent image reconstruction. Then, the computer device can control the backup data acquisition device to collect the original data at the fault position and after the fault position, and use the original data collected by the original data acquisition device before the fault position and the original data collected by the backup data acquisition device at the fault position and after the fault position as the data to be reconstructed.
[0086] In the above imaging method, if the detection result shows that there is an abnormality, the original data collected by the backup data acquisition device is used as the data to be reconstructed; the original data includes the data collected by the backup data acquisition device before the fault position, the data collected at the fault position and after the fault position; if the detection result shows that there is no abnormality, the original data collected by the original data acquisition device before the fault position and the original data collected by the backup data acquisition device at the fault position and after the fault position are used as the data to be reconstructed. This method can accurately determine whether the fault of the original data acquisition device affects the original data collected before the fault position based on whether there is an abnormality in the original data collected before the fault position, thereby accurately determining the acquisition range of the backup data acquisition device based on the detection result to accurately determine the data to be reconstructed.
[0087] The above embodiments are all detailed introductions to the process of obtaining the data to be reconstructed. After obtaining the data to be reconstructed, a subsequent image reconstruction process is required. Figure 5 As shown, the specific contents of reconstructing the data to be reconstructed by the original image reconstruction device or the backup image reconstruction device include the following steps:
[0088] S501 , when an original image reconstruction device fails, reconstructing the data to be reconstructed by using a backup image reconstruction device.
[0089] In the embodiment of the present application, there are multiple situations in which the original image reconstruction device fails. In the first situation, the original image reconstruction device has failed before the image reconstruction. Then, the computer device directly controls the backup image reconstruction device to reconstruct the data to be reconstructed.
[0090] In the second case, the original image reconstruction device may fail during the image reconstruction process, and the original image reconstruction device and the backup image reconstruction device may be controlled to simultaneously reconstruct the data to be reconstructed. Alternatively, the original image reconstruction device may be controlled to first reconstruct the data to be reconstructed separately, and if the original image reconstruction device fails, then the backup image reconstruction device is controlled to reconstruct the data to be reconstructed.
[0091] In the third case, if the original image reconstruction device fails after the image reconstruction is completed, the backup image reconstruction device is controlled to perform image reconstruction during the next reconstruction process.
[0092] S502: When there is no failure in the original image reconstruction device, image reconstruction is performed on the data to be reconstructed by using the original image reconstruction device.
[0093] In the embodiment of the present application, if the original image reconstruction device has no fault or the probability of fault is low, the computer device can control the original image reconstruction device to reconstruct the data to be reconstructed to obtain a reconstructed image.
[0094] In the above imaging method, when the original image reconstruction device fails, the backup image reconstruction device is used to reconstruct the data to be reconstructed; when the original image reconstruction device does not fail, the original image reconstruction device is used to reconstruct the data to be reconstructed. This method analyzes whether the original image reconstruction device fails, and based on the analysis result, the backup image reconstruction device and the original image reconstruction device cooperate to ensure the reliability of the image reconstruction process and avoid the failure of the original image reconstruction device to reconstruct the image.
[0095] As a specific embodiment of the present application, the imaging process is described in detail below. In one embodiment, Figure 6 As shown, the imaging method includes two different implementations. One implementation includes the contents of steps S601, S605 and S606. Another implementation includes the contents of steps S602-S606.
[0096] S601, in response to the fault prompt information on the display interface, when the original data acquisition device and the backup data acquisition device are collecting data at the same time and the original data acquisition device is faulty, the original data collected by the backup data acquisition device is used as the data to be reconstructed;
[0097] S602, responding to the fault prompt information on the display interface, when the original data acquisition device is collecting data separately and the original data acquisition device is faulty, determining whether the original data collected by the original data acquisition device before the fault location is abnormal;
[0098] S603, if the detection result shows that there is an abnormality, the original data collected by the standby data collection device is used as the data to be reconstructed; the original data includes the data collected by the standby data collection device before the fault location, the fault location and the data collected after the fault location;
[0099] S604, if the detection result shows that there is no abnormality, the original data collected by the original data collection device before the fault location and the original data collected by the backup data collection device at the fault location and after the fault location are used as data to be reconstructed;
[0100] S605, when the original image reconstruction device fails, reconstructing the data to be reconstructed by using the backup image reconstruction device;
[0101] S606: When there is no failure in the original image reconstruction device, image reconstruction is performed on the data to be reconstructed by using the original image reconstruction device.
[0102] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
[0103] In one embodiment, an imaging system 10 is also provided. Figure 7 As shown, the imaging system 10 includes an original data acquisition device 101, a backup data acquisition device 102, an original image reconstruction device 103, a backup image reconstruction device 104 and a computer device 105;
[0104] The computer device 105 is used to respond to the fault prompt information on the display interface. When the original data acquisition device 101 fails, the computer device 105 determines the data to be reconstructed based on the original data collected by the original data acquisition device 101 and the backup data acquisition device 102; and reconstructs the data to be reconstructed through the original image reconstruction device 103 or the backup image reconstruction device 104 to obtain a reconstructed image.
[0105] In the embodiment of the present application, the original data acquisition device 101, the backup data acquisition device 102, the original image reconstruction device 103, and the backup image reconstruction device 104 in the imaging system 10 are all connected to the computer device 105, and the computer device 105 can control the operation of the original data acquisition device 101, the backup data acquisition device 102, the original image reconstruction device 103, and the backup image reconstruction device 104.
[0106] For example, the computer device 105 can control the raw data acquisition device 101 to acquire raw data according to the imaging requirements triggered by the user, and if a failure of the raw data acquisition device 101 is detected during the acquisition process, the computer device 105 controls the raw data acquisition device 101 to stop acquiring raw data, and controls the standby data acquisition device 102 to reacquire or continue acquiring to obtain data to be reconstructed.
[0107] Furthermore, the computer device 105 can also control the original image reconstruction device 103 to perform image reconstruction. If the original image reconstruction device 103 fails during the reconstruction process, the original image reconstruction device 103 is controlled to stop the image reconstruction process, and the backup image reconstruction device 104 is controlled to perform image reconstruction to obtain a reconstructed image.
[0108] The imaging system 10 includes an original data acquisition device 101, a backup data acquisition device 102, an original image reconstruction device 103, a backup image reconstruction device 104, and a computer device 105; the computer device 105 is used to determine the data to be reconstructed based on the original data acquired by the original data acquisition device 101 and the backup data acquisition device 102 when the original data acquisition device 101 fails; and reconstruct the data to be reconstructed through the original image reconstruction device 103 or the backup image reconstruction device 104 to obtain a reconstructed image. With respect to the imaging process, by arranging the backup data acquisition device 102 and the backup image reconstruction device 104 in the imaging system 10, when the original data acquisition device 101 fails, the cooperation between the original data acquisition device 101 and the backup data acquisition device 102 can avoid the failure of the original data acquisition device 101 to continue data acquisition. And in the subsequent reconstruction process, the original image reconstruction device 103 and the backup image reconstruction device 104 cooperate to perform image reconstruction to avoid the original image reconstruction device 103 failing and being unable to reconstruct the image. In this way, based on the added backup data acquisition device 102 and the backup image reconstruction device 104, it can be ensured that the data acquisition and image reconstruction process will not be interrupted, thereby improving the imaging reliability.
[0109] In one embodiment, Figure 8 As shown, the imaging system 10 further includes a detection device 106 and a switching device 107. The input ends of the original data acquisition device 101 and the backup data acquisition device 102 are connected to the detection device 106. The switching device 107 is arranged between the output ends of the original data acquisition device 101 and the backup data acquisition device 102 and the input ends of the original image reconstruction device 103 and the backup image reconstruction device 104.
[0110] The detection device 106 is used to perform detection scanning on the acquisition object to assist the original data acquisition device 101 and / or the backup data acquisition device 102 in acquiring original data;
[0111] The switching device 107 is used to send the original data acquired by the original data acquisition device 101 and / or the backup data acquisition device 102 to the original image reconstruction device 103 and / or the backup image reconstruction device 104 .
[0112] In the embodiment of the present application, the type of the detection device 106 can be determined based on the type of the medical imaging device. For example, when the medical imaging device is a computed tomography (CT) device, the detection device 106 can be a CT detector; when the medical imaging device is a magnetic resonance imaging (MRI) device, the detection device 106 can be an MRI detector; when the medical imaging device is a PET device, the detection device 106 can be a PET detector or a single-photon emission computed tomography (SPECT) device. For example, a SPECT can be a SPECT gamma camera.
[0113] In addition, the switching device 107 disposed between the two data acquisition devices and the two image reconstruction devices may be a switch and a router.
[0114] The imaging system 10 further includes a detection device 106 and a switching device 107. The input ends of the original data acquisition device 101 and the spare data acquisition device 102 are both connected to the detection device 106. The switching device 107 is arranged between the output ends of the original data acquisition device 101 and the spare data acquisition device 102 and the input ends of the original image reconstruction device 103 and the spare image reconstruction device 104. The detection device 106 is used to perform detection scanning on the acquisition object to assist the original data acquisition device 101 and / or the spare data acquisition device 102 in acquiring original data. The switching device 107 is used to send the original data acquired by the original data acquisition device 101 and / or the spare data acquisition device 102 to the original image reconstruction device 103 and / or the spare image reconstruction device 104. By arranging the detection device 106 between the detection object and the two data acquisition devices, the reliability of the acquisition of the original data can be guaranteed. At the same time, by arranging the switching device 107 between the two data acquisition devices and the two image reconstruction devices, the reliability of the interaction between the data to be reconstructed between different devices can be guaranteed, thereby ensuring the reliability of the imaging process.
