The rotating end of the scanning device is provided with a detection device and a slip ring, and the detection device is connected to the slip ring for communication. The detection device is used to obtain scanning data (also called raw data) and transmit the scanning data to the reconstruction device through the slip ring, so that the reconstruction device uses the scanning data to perform image reconstruction to generate a cross-sectional image of the inspected object.

[0003] In the related art, the scanning data acquired by the detection device must be transmitted to the reconstruction device via a slip ring, which results in the transmission rate of the scanning data being limited by the bandwidth of the slip ring, which affects the efficiency of the reconstruction device in generating cross-sectional images.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0006] The embodiment of the present disclosure provides a scanning device, which can improve the efficiency of a reconstruction device in generating cross-sectional images.

[0007] According to a first aspect of the present disclosure, a scanning device is provided, the scanning device comprising:

[0008] A rack body, wherein the rack body is provided with a communication device and a rotatable rotating end;

[0009] A detection device, fixed to the rotating end;

[0010] The distributed reconstruction device is fixed to the rotating end and is communicatively connected to the detection device and the communication device.

[0011] In some embodiments, the distributed reconstruction device includes a master reconstruction device and at least one slave reconstruction device communicatively connected to the master reconstruction device; the detection device and the communication device are both communicatively connected to the master reconstruction device.

[0012] In some embodiments, the slave reconstruction device includes multiple slave reconstruction devices, and the multiple slave reconstruction devices are connected to the master reconstruction device in parallel.

[0013] In some embodiments, the slave reconstruction device includes multiple slave reconstruction devices, and the multiple slave reconstruction devices are serially connected to the master reconstruction device.

[0014] In some embodiments, the distributed reconstruction devices are distributed along the circumference of the rotating end.

[0015] In some embodiments, at least one reconstruction device in the distributed reconstruction devices includes a processor, a memory, a graphics card, and a network interface connected via a system bus, the processor is used to provide computing and control capabilities, the memory is used to store scanning data, and the graphics card is used to process the scanning data based on instructions from the processor.

[0016] In some embodiments, the scanning device further comprises a data storage device communicatively coupled to the detection device.

[0017] In some embodiments, the distributed reconstruction device includes a master reconstruction device and a slave reconstruction device, and the data storage device is communicatively connected to the master reconstruction device.

[0018] In some embodiments, the communication device is a slip ring or a wireless communication device.

[0019] In some embodiments, the scanning device is a computed tomography device.

[0020] The scanning device provided by the embodiment of the present disclosure can achieve the following technical effects:

[0021] The scanning device provided by the embodiment of the present disclosure sets the distributed reconstruction device on the rotating end so that the distributed reconstruction device can be directly connected to the detection device for communication. In this way, the detection device does not need to send the scanning data to the detection device through the slip ring, but can directly send the scanning data to the distributed reconstruction device, which overcomes the limitation of the bandwidth of the slip ring on the transmission rate of the scanning data, which will significantly reduce the transmission time of the raw data and improve the real-time transmission of the raw data. The distributed reconstruction device can receive a large amount of scanning data more quickly, which helps to improve the efficiency of the distributed reconstruction device in generating cross-sectional images and also improves the real-time performance of the cross-sectional images.

[0022] Moreover, the data volume of the cross-sectional image is much smaller than the data volume of the corresponding scan data. Compared with the transmission of scan data, the communication device has less pressure to transmit the cross-sectional image, which reduces the bandwidth requirements of the communication device and helps to reduce the cost of the communication device. Since the data volume of the cross-sectional image is much smaller than the data volume of the corresponding scan data, the scanning device provided by the embodiment of the present disclosure can be configured with a communication device with a smaller bandwidth to meet the data transmission requirements. Therefore, the communication device in the embodiment of the present disclosure can be a slip ring with a smaller bandwidth, or it can be a wireless communication device.

[0023] Furthermore, since the data volume of the cross-sectional image is relatively small, the time required to transmit data to an external device (such as a display device) via a communication device can also be reduced, thereby increasing the running speed of the entire process and improving the real-time performance of image reconstruction.

[0048] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0050] The scanning system generally includes a scanning device and a reconstruction device. The rotating end of the scanning device is provided with a detection device and a slip ring, and the detection device is connected to the slip ring for communication. The detection device is used to obtain scanning data (also called raw data) and transmit the scanning data to the reconstruction device through the slip ring, so that the reconstruction device uses the scanning data to perform image reconstruction to generate a cross-sectional image of the inspected object.

[0051] In the related art, the scanning data acquired by the detection device must be transmitted to the reconstruction device via a slip ring, which results in the transmission rate of the scanning data being limited by the bandwidth of the slip ring, which affects the efficiency of the reconstruction device in generating cross-sectional images.

[0052] Taking a CT (Computer Tomography) scanning device as an example, a tube is also provided at the rotating end of the scanning device. During the scanning process, the rotating end surrounds the object under inspection and rotates at high speed. The tube emits X-rays and the detection device receives attenuation signal data, which is the generated data. Figure 1 FIG. 1 shows a schematic diagram of the connection of some devices of a scanning system in the related art, such as Figure 1As shown, the detection device transmits the raw data to the fixed part of the scanning device through the slip ring, and the optical fiber in the fixed part transmits the raw data to the reconstruction device. After receiving the raw data, the reconstruction device reconstructs the raw data into a cross-sectional preview image of the inspected object in real time through preprocessing, image reconstruction and image post-processing, and then sends the cross-sectional preview image to the display device for display. Among them, preprocessing includes operations such as correction and reorganization of raw data; image reconstruction is the process of performing back projection using raw data, thereby converting raw data into the initial cross-sectional preview image; image post-processing is to use filtering, convolution and other methods to perform operations such as denoising and contrast enhancement on the initial cross-sectional image to obtain the final cross-sectional preview image.

[0053] In addition, after receiving the raw data, the reconstruction device can also send the raw data to the data storage device for storage. When the scan is completed, all the raw data are saved in the data storage device of the reconstruction device. At this time, according to the command of the control device, the reconstruction device reads the saved raw data in the data storage device to perform the post-imaging task, reconstruct a more accurate cross-sectional image, and send the reconstructed cross-sectional image to the display device for display.

[0054] From the above content, it can be seen that the raw data acquired by the detection device must be transmitted to the reconstruction device through the slip ring. In order to adapt to the needs of raw data acquisition and transmission with a larger amount of data, it is necessary to use a slip ring with a larger bandwidth to transmit the raw data. However, the slip ring with a large bandwidth is expensive, which will significantly increase the cost of the scanning device. If the raw data to be transmitted is large, due to the limitation of the slip ring transmission bandwidth, the raw data usually needs to be compressed and then passed to the reconstruction device through the slip ring. In this case, after the reconstruction device receives the raw data, it needs to decompress the raw data before it can be used, which will significantly increase the transmission time of the raw data and reduce the real-time performance of the raw data transmission, thereby affecting the efficiency of the reconstruction device in generating cross-sectional images. Moreover, decompressing the raw data will also cause a waste of computing resources at the reconstruction end.

[0055] In addition, the reconstruction equipment in the related art is usually a server with a higher configuration. The server needs to be installed separately and configured with corresponding network and power supply facilities. This leads to limited application scenarios of the reconstruction equipment in the related art. For example, the reconstruction equipment in the related art cannot be used in vehicle-mounted mobile scanning devices (such as vehicle-mounted mobile CT machines).

[0056] Combination Figures 2 to 4As shown, the embodiment of the present disclosure provides a scanning device 100, which may be a computer tomography device, etc. The scanning device 100 includes a frame body 101, a detection device 105, and a distributed reconstruction device 104, wherein the frame body 101 is provided with a communication device 103 and a rotatable rotating end 102, the communication device 103 can communicate with an external device, and the number of distributed reconstruction devices 104 is multiple. The detection device 105 and the distributed reconstruction device 104 are both fixed to the rotating end 102, and it can be understood that the detection device 105 and the distributed reconstruction device 104 can rotate with the rotating end 102.

[0057] Although Figures 2 to 4 Only one reconstruction device is shown, but the Figure 6 and Figure 7 As shown, there are multiple distributed reconstruction devices 104. The distributed reconstruction devices 104 are distributed along the circumference of the rotating end 102. The spacing between adjacent distributed reconstruction devices 104 can be determined according to actual design requirements.

[0058] The distributed reconstruction device 104 is communicatively connected to the detection device 105 and the communication device 103. Therefore, the distributed reconstruction device 104 can directly receive the scan data (also called raw data) from the detection device 105, and use the scan data to perform image reconstruction to generate a cross-sectional image of the object under inspection. After the distributed reconstruction device 104 generates the cross-sectional image of the object under inspection, the cross-sectional image can be sent to an external device through the communication device 103. The external device can be at least one of the control device 300, the display device 200, and the storage device. In this embodiment, the distributed reconstruction device 104 directly obtains the scan data from the detection device 105, which can be used for real-time imaging.

[0059] In the embodiments of the present disclosure, Figure 3 As shown, the communication device 103 may be a slip ring.

[0060] In the embodiments of the present disclosure, Figure 4 As shown, the communication device 103 may be a wireless communication device.

[0061] It should be noted that the distributed reconstruction device 104 provided in the embodiment of the present disclosure is a miniaturized embedded computing device so as to be installed on the rotating end 102. It is understandable that the size of the distributed reconstruction device 104 can be determined according to the size of the rotating end 102 and each device installed on the rotating end 102. The distributed reconstruction device 104 can be an embedded computing device based on ARM, or a microprocessor based on X86, etc.

[0062] like Figure 5As shown, at least one reconstruction device in the distributed reconstruction device 104 includes a processor 1041, a memory 1042, a graphics card 1043 and a network interface 1044 connected through a system bus. The processor 1041 of the distributed reconstruction device 104 is used to provide computing and control capabilities, and the memory 1042 is used to store scan data. The memory 1042 includes a non-volatile memory 1042. The non-volatile memory 1042 stores an operating system, a computer program and a database. The reconstruction device also includes a volatile memory 1042, which can provide an environment for the operation of the operating system and the computer program in the non-volatile memory 1042, and the database is used to store scan data. The graphics card 1043 is used for image reconstruction calculation, specifically, the graphics card 1043 is used to process the scan data based on the instructions of the processor 1041. The network interface 1044 of the distributed reconstruction device 104 is used to communicate with an external terminal through a network connection. When the computer program is executed by the processor 1041, the relevant steps of image reconstruction can be implemented.

[0063] Taking the scanning device 100 as a CT machine as an example, the rotating end 102 of the scanning device 100 is also provided with a tube (not shown in the figure). During the scanning process, the rotating end 102 surrounds the object to be inspected and rotates at high speed. The tube emits X-rays and the detection device 105 receives attenuation signal data, which is the scanning data. The distributed reconstruction device 104 can directly receive the scanning data from the detection device 105, and use the scanning data to perform image reconstruction to generate a cross-sectional image of the object to be inspected.

[0064] The scanning device 100 provided in the embodiment of the present disclosure sets the distributed reconstruction device 104 on the rotating end 102, so that the distributed reconstruction device 104 can be directly connected to the detection device 105. In this way, the detection device 105 does not need to send the scanning data to the detection device 105 through the slip ring, but can directly send the scanning data to the distributed reconstruction device 104, which overcomes the limitation of the bandwidth of the slip ring on the transmission rate of the scanning data, which can significantly reduce the transmission time of the raw data and improve the real-time transmission of the raw data. The distributed reconstruction device 104 can receive a large amount of scanning data more quickly, which helps to improve the efficiency of the distributed reconstruction device 104 in generating cross-sectional images and also improves the real-time performance of the cross-sectional images.

[0065] Moreover, the data volume of the cross-sectional image is much smaller than the data volume of the corresponding scan data. Specifically, the data volume of the cross-sectional image is generally only tens of megabytes, while the data volume of the scan data corresponding to the cross-sectional image will be tens of GB (one GB equals 1024 megabytes). Compared with transmitting scan data, the communication device 103 has less pressure to transmit the cross-sectional image, which reduces the bandwidth requirements of the communication device 103 and helps to reduce the cost of the communication device 103. Since the data volume of the cross-sectional image is much smaller than the data volume of the corresponding scan data, the scanning device 100 provided in the embodiment of the present disclosure can be configured with a communication device 103 with a smaller bandwidth to meet the data transmission requirements. Therefore, the communication device 103 in the embodiment of the present disclosure can be a slip ring with a smaller bandwidth, or it can be a wireless communication device.

[0066] Furthermore, since the data volume of the cross-sectional image is relatively small, the time required to transmit data to an external device (such as the display device 200) via the communication device 103 can also be reduced, thereby increasing the running speed of the entire process and improving the real-time performance of image reconstruction.

[0067] Since the distributed reconstruction device 104 is disposed at the rotating end 102 of the scanning device 100, the distributed reconstruction device 104 can use the network and power supply facilities of the scanning device, and there is no need to configure the network and power supply facilities separately. Therefore, the distributed reconstruction device 104 can be applied to a vehicle-mounted mobile scanning device (such as a vehicle-mounted mobile CT machine).

[0068] In some embodiments, in combination Figures 2 to 4 As shown, the scanning device 100 further includes a data storage device 106, which is in communication with the distributed reconstruction device 104. In view of the working environment of the rotating end 102, the data storage device 106 should be a storage device that can withstand high centrifugal forces, such as an SSD (Solid State Disk).

[0069] In some embodiments, after receiving the scan data from the detection device 105, the distributed reconstruction device 104 can use the scan data to perform image reconstruction to generate a cross-sectional image of the object under inspection, and can send the scan data to the data storage device 106 for storage. The data storage device 106 stores all scan data after the scan is completed, and the distributed reconstruction device 104 can perform image reconstruction based on the scan data in the data storage device 106 to obtain high-quality images for clinical diagnosis.

[0070] In some embodiments, in combination Figures 2 to 4As shown, the scanning device 100 also includes a data storage device 106, which is also in communication with the detection device 105. After the detection device 105 acquires the scanning data, it can send the scanning data to the distributed reconstruction device 104, and can also send the scanning data to the data storage device 106 for storage.

[0071] Although Figures 2 to 4 Only one reconstruction device is shown, but the Figure 6 and Figure 7 As shown, there are multiple distributed reconstruction devices 104. Specifically, the embodiment of the present disclosure can set a corresponding number of distributed reconstruction devices 104 with computing power performance on the rotating end 103 according to different requirements of different scanning device types for computing performance and computing power performance of different distributed reconstruction devices 104. In addition, setting multiple distributed reconstruction devices 104 can improve reliability and help reduce subsequent maintenance costs.

[0072] Combination Figure 6 and Figure 7 As shown, the distributed reconstruction device 104 includes a master reconstruction device 104a and at least one slave reconstruction device 104b communicatively connected to the master reconstruction device. The data storage device 106 is communicatively connected to the master reconstruction device 106.

[0073] In some embodiments, the reconstruction device 104b includes multiple, combined Figure 6 As shown, the multiple distributed reconstruction devices 104 include a master reconstruction device 104a and multiple slave reconstruction devices 104b, and the multiple slave reconstruction devices 104b are serially connected to the master reconstruction device 104a. Specifically, each slave reconstruction device 104b is respectively connected to the master reconstruction device 104a in communication, and the detection device 105 and the communication device 103 are both connected to the master reconstruction device 104a in communication.

[0074] In some embodiments, the slave reconstruction device 104b includes multiple. Figure 7 As shown, the distributed reconstruction device 104 includes a master reconstruction device 104a and multiple slave reconstruction devices 104b, the multiple slave reconstruction devices 104b are serially connected to the master reconstruction device 104a, and the detection device 105 and the communication device 103 are both communicatively connected to the master reconstruction device 104a. Specifically, the master reconstruction device 104a is communicatively connected to the first slave reconstruction device 104b, the first slave reconstruction device 104b is communicatively connected to the second slave reconstruction device 104b, and so on, the last slave reconstruction device 104b is communicatively connected to the master reconstruction device 104a.

[0075] Combination Figure 8As shown, an embodiment of the present disclosure provides a scanning system, which includes a display device 200 and the scanning apparatus 100 provided in the above embodiment, and the display device 200 is communicatively connected with the communication device 103 in the scanning apparatus 100 .

[0076] In some embodiments, in combination Figure 6 and Figure 8 As shown, the number of distributed reconstruction devices 104 in the scanning device 100 can be multiple, and the distributed reconstruction devices 104 include a main reconstruction device 104a and at least one slave reconstruction device 104b, each slave reconstruction device 104b is respectively communicatively connected to the main reconstruction device 104a, the detection device 105 and the communication device 103 are both communicatively connected to the main reconstruction device 104a, and the display device 200 is communicatively connected to the communication device 103 in the scanning device 100.

[0077] In some embodiments, in combination Figure 7 and Figure 8 As shown, the number of distributed reconstruction devices 104 can be multiple, and the distributed reconstruction devices 104 include a master reconstruction device 104a and multiple slave reconstruction devices 104b. The master reconstruction device 104a and the multiple slave reconstruction devices 104b are connected in series, the detection device 105 and the communication device 103 are both connected in communication with the master reconstruction device 104a, and the display device 200 is connected in communication with the communication device 103 in the scanning device 100.

[0078] In some embodiments, in combination Figure 3 and Figure 8 As shown, the communication device 103 may be a slip ring, and the display device 200 may be communicatively connected with the communication device 103 via an optical fiber.

[0079] In some embodiments, in combination Figure 4 and Figure 8 As shown, the communication device 103 is a wireless communication device, and the display device 200 can achieve communication connection with the communication device 103 in a wireless transmission manner.

[0080] In some embodiments, Figure 8 As shown, the scanning system further includes a control device 300 , which is communicatively connected to the communication device 103 in the scanning apparatus 100 .

[0081] In some embodiments, in combination Figure 6 and Figure 8As shown, the number of distributed reconstruction devices 104 in the scanning device 100 can be multiple, and the distributed reconstruction devices 104 include a main reconstruction device 104a and at least one slave reconstruction device 104b, each slave reconstruction device 104b is respectively communicated with the main reconstruction device 104a, the detection device 105 and the communication device 103 are both communicated with the main reconstruction device 104a, and the control device 300 is communicated with the communication device 103 in the scanning device 100.

[0082] In some embodiments, in combination Figure 7 and Figure 8 As shown, the number of distributed reconstruction devices 104 can be multiple, and the distributed reconstruction devices 104 include a master reconstruction device 104a and multiple slave reconstruction devices 104b. The master reconstruction device 104a and the multiple slave reconstruction devices 104b are connected in series, the detection device 105 and the communication device 103 are both connected in communication with the master reconstruction device 104a, and the control device 300 is connected in communication with the communication device 103 in the scanning device 100.

[0083] In the embodiment of the present disclosure, Figure 3 and Figure 8 As shown, the communication device 103 may be a slip ring, and the control device 300 may be connected to the communication device 103 via an optical fiber.

[0084] In some embodiments, in combination Figure 4 and Figure 8 As shown, the communication device 103 is a wireless communication device, and the control device 300 can achieve communication connection with the communication device 103 in a wireless transmission manner.

[0085] The number of distributed reconstruction devices 104 in the scanning device 100 can be multiple, and the multiple distributed reconstruction devices 104 need to perform reconstruction tasks in a collaborative manner. The multiple distributed reconstruction devices 104 include a master reconstruction device 104a and at least one slave reconstruction device 104b. The master reconstruction device 104a can receive the scanning data sent by the detection device 105 and assign reconstruction tasks to the slave reconstruction devices 104b. The master reconstruction device 104a sends corresponding scanning data to each slave reconstruction device 104b according to the assignment of reconstruction tasks to each slave reconstruction device 104b. The slave reconstruction device 104b receives the reconstruction task and scanning data sent by the master reconstruction device 104a, performs reconstruction calculation based on the received reconstruction task and scanning data, and then returns the reconstruction calculation result to the master reconstruction device 104a. The master reconstruction device 104a generates a cross-sectional image of the object under inspection based on the reconstruction calculation results returned by all the slave reconstruction devices 104b.

[0086] In the disclosed embodiment, during the scanning process, the distributed reconstruction device 104 will reconstruct the raw data into a cross-sectional preview image of the object under inspection in real time based on the scanning data obtained in real time by the detection device 105, and send the cross-sectional preview image to the display device 200 for display.

[0087] It is understandable that during the scanning process, after the distributed reconstruction device 104 receives the scan data from the detection device 105, it can use the scan data to perform image reconstruction to generate a cross-sectional preview image of the inspected object, and can send the scan data to the data storage device 106 for storage. When the scan is completed, all the raw data are stored in the data storage device 106 of the distributed reconstruction device 104. At this time, according to the command of the control device 300, the distributed reconstruction device 104 reads the saved raw data in the data storage device 106 to perform the post-construction imaging task, reconstructs a more accurate cross-sectional image, and sends the reconstructed cross-sectional image to the display device 200 for display.

[0088] for Figure 6 The master reconstruction device 104a is connected to the slave reconstruction device 104b. The master reconstruction device 104a sends corresponding scan data to each slave reconstruction device 104b according to the allocation of reconstruction tasks of each slave reconstruction device 104b. After obtaining the reconstruction calculation result, each slave reconstruction device 104b can directly return the reconstruction calculation result to the master reconstruction device 104a. The master reconstruction device 104a generates a cross-sectional image of the object under inspection based on the reconstruction calculation results returned by all slave reconstruction devices 104b. It can be understood that during the scanning process, the scan data sent by the master reconstruction device 104a is obtained in real time by the detection device 105; when the scanning is completed, the scan data sent by the master reconstruction device 104a is read from the data storage device 106.

[0089] for Figure 7The connection relationship between the master reconstruction device 104a and the slave reconstruction device 104b is shown. The master reconstruction device 104a sends all scan data to the first slave reconstruction device 104b according to the allocation of reconstruction tasks of each slave reconstruction device 104b. After the first slave reconstruction device 104b retains the scan data it needs, it sends the remaining scan data to the second slave reconstruction device 104b. After the second slave reconstruction device 104b retains the scan data it needs, it sends the remaining scan data to the third slave reconstruction device 104b, and so on, until all slave reconstruction devices 104b obtain the scan data they need. After each slave reconstruction device 104b obtains the reconstruction calculation result, it can send the reconstruction calculation result to the next adjacent slave reconstruction device 104b; the slave reconstruction device 104b can send the reconstruction calculation result obtained by itself and the reconstruction calculation result sent by the previous adjacent slave reconstruction device 104b to the next adjacent slave reconstruction device 104b. Finally, the last slave reconstruction device 104b returns the reconstruction calculation results obtained by all slave reconstruction devices 104b to the master reconstruction device 104a. The master reconstruction device 104a generates a cross-sectional image of the object under inspection based on the reconstruction calculation results returned by all slave reconstruction devices 104b.
