[0026] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0027] In the present disclosure, unless otherwise specified, the use of the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, timing relationship, or importance relationship of these elements, and such terms are only used to distinguish one element from another element. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, based on the description of the context, they may also refer to different instances.

[0028] The terms used in the description of various examples in this disclosure are only for the purpose of describing specific examples and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element can be one or more. In addition, the term "and / or" used in this disclosure covers any one of the listed items and all possible combinations.

[0029] As mentioned above, the medical imaging system also includes components for performing various auxiliary functions, which can be referred to as auxiliary components or peripheral components. The operator can make these peripheral components perform corresponding functions by operating them separately. For example, the operator can directly operate the touch panel in the medical imaging system. However, with the development of intelligent technology of medical equipment, it is hoped that more and more peripheral components can be uniformly managed by the main control machine of the medical imaging system. In some embodiments, more and more peripheral components use ARM (Advanced RISC Machine) processors or single-board computers and have Ethernet interfaces for system communication. In view of this, the present disclosure provides a medical imaging system, a method for a medical imaging system, an electronic device, a non-transient computer-readable storage medium, and a computer program product to achieve unified management of peripheral components of the medical imaging system by the main control machine.

[0030] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0031] Figure 1 A structural block diagram of a medical imaging system 100 according to an embodiment of the present disclosure is shown.

[0032] The medical imaging system 100 includes a main control machine 110, and the main control machine 110 includes a main console 111 and a scanning and reconstruction system 112. The medical imaging system 100 also includes an Ethernet switch 120, a first peripheral component 130, and a second peripheral component 140. The first peripheral component 130 is connected to the scanning and reconstruction system 112 based on a first communication protocol; and the second peripheral component 140 is connected to at least one of the main console 111 and the scanning and reconstruction system 112 through the Ethernet switch 120 based on a second communication protocol of an application layer different from the first communication protocol. For example, the second peripheral component 140 can be connected to the main console 111, can be connected to the scanning and reconstruction system 112, or can be connected to both the main console 111 and the scanning and reconstruction system 112. In an example, the main console 111 and the scanning and reconstruction system 112 can be located in different rooms, for example, the main console 111 is located in an operating room, and the scanning and reconstruction system 112 is located in an electrical room or an equipment room. The main console 111 is mainly used to input programs and imaging parameters, intervene in and control the scanning process, etc., and may have a human-computer interaction interface for displaying the operating parameters of various peripheral components to the operator. The scanning and reconstruction system 112 is used to perform high-speed calculations based on the original data collected by the magnetic resonance system to obtain reconstructed magnetic resonance image data.

[0033] As an example, the medical imaging system may include a magnetic resonance imaging (MRI) system, a computerized tomography (CT) system, a positron emission tomography-computed tomography (PET-CT) system, or a digital subtraction angiography (DSA) system. Taking the CT system as an example, its main control machine may include a special-purpose computer, which may be used, for example, to issue instructions for controlling the emission of X-ray beams or to process the rays detected by the detector for imaging. In the example, the main control machine may be an integrated computer or may include a plurality of physically separated computers. For example, the main control machine may be separately arranged in different rooms (treatment room and equipment room). As an example, the first peripheral component or the second peripheral component may include a component for performing auxiliary functions, such as a voice intercom for a doctor to have a conversation with a patient. The first peripheral component or the second peripheral component may have different types of communication interfaces.

[0034] In this way, unified management of different types of peripheral components of the medical imaging system can be achieved through the main control computer.

[0035] According to some embodiments, the second peripheral component may include one of the following: a camera, a video camera, a touch pad, or a voice intercom.

[0036] Accordingly, the camera, video camera, touch panel or voice intercom may have an Ethernet port to communicate with at least one of the main console 111 and the scanning and reconstruction system 112 through an Ethernet switch.

[0037] According to some embodiments, the first communication protocol may include one of a USB protocol, a serial communication protocol, a CAN protocol, and a PCIe protocol. For example, the first communication protocol may be a PCIe (Peripheral Component Interconnect express) protocol, which is a high-speed serial computer expansion bus standard. Accordingly, the first peripheral component 130 may include a radiographic imaging device, and the radiographic imaging device may be connected to the scanning and reconstruction system 112 in communication based on the PCIe protocol. For example, the first communication protocol may be a CAN (Controller Area Network) protocol. Accordingly, the first peripheral component 130 may include a cooling device for cooling the medical imaging system, and the cooling device may be connected to the scanning and reconstruction system 112 in communication based on the CAN protocol.

[0038] In an example, the second communication protocol may include a remote procedure call protocol (eg, a gRPC protocol), which may, for example, use HTTP / 2 as a transport protocol.

[0039] According to some embodiments, the second communication protocol may include a Simple Network Management Protocol (SNMP). The model of the Simple Network Management Protocol (SNMP) includes a management station and a managed device, wherein the master computer may serve as a management station for sending commands to a managed device (e.g., a voice intercom). The management station may run a management program, and correspondingly, the managed device may run an agent program to communicate with the management program running in the management station. The management program and the agent program in SNMP may work in a client-server manner. The management program runs the client program of SNMP, and the agent program runs the server program of SNMP. In the example, the master computer 110 may be connected to the second peripheral component for communication based on the v3 version of SNMP.

[0040] Figure 2 A structural block diagram of either a main console or a scanning and reconstruction system of a medical imaging system according to an embodiment of the present disclosure is shown.

[0041] like Figure 2 As shown, the console 111 or the scanning and reconstruction system 112 may include:

[0042] The IP address allocation module 210 is configured to allocate an Internet Protocol IP address to the second peripheral component in response to receiving an Internet Protocol IP address request from the second peripheral component;

[0043] The reset instruction module 220 is configured to send a reset instruction to the second peripheral component based on the IP address and the second communication protocol (such as SNMP) in response to the main control machine being turned on or restarted, so that the second peripheral component performs a program restart;

[0044] The reset information receiving module 230 is configured to receive information from the second peripheral component indicating that the second peripheral component has completed program restart; and

[0045] The function operation instruction module 240 is configured to send a function operation instruction to the second peripheral component based on the IP address and the second communication protocol (such as SNMP) in response to receiving the information, so as to control the function operation of the second peripheral component.

[0046] In the example, the main control machine 110 can act as a dynamic host configuration protocol DHCP server. When receiving an Internet Protocol IP address request from the second peripheral component, the IP address allocation module 210 can automatically allocate an IP address and a subnet mask for the second peripheral component. The main control machine 110 can install the TCP / IP protocol and can set a static IP address, a subnet mask, a default gateway, etc. After the second peripheral component obtains the corresponding IP address, it can communicate with the main control machine 110 based on the IP address.

[0047] When the main control machine 110 is turned on or restarted, the reset indication module 220 sends a reset instruction to the second peripheral component based on the IP address and the second communication protocol (such as SNMP) to restart the program of the second peripheral component. In addition, the reset information receiving module 230 can receive information indicating that the second peripheral component has completed the program restart from the second peripheral component. In some scenarios, the main control machine 110 and the second peripheral component may be shut down after a long period of shutdown or an error occurs during operation. Therefore, whenever the main control machine 110 is turned on or restarted, the program of the second peripheral component is restarted, and subsequent functional operations are performed only after confirming that the second peripheral component has completed the program restart. Therefore, it is possible to effectively avoid the occurrence of errors caused by internal errors in the second peripheral component or the incoordination of the operating status of the second peripheral component and the main control machine 110. This is particularly advantageous in the process of performing medical imaging examinations. In an example, based on the SNMP probe operation, the host 110 may use a Set message to send a reset instruction to the second peripheral component; and the second peripheral component may use a trap message to directly send information indicating that the second peripheral component has completed program restart to the host 110.

[0048] In an example, the function operation instruction sent by the function operation instruction module 240 to the second peripheral component may include an instruction to set the high or low level of a general purpose input / output port (GPIO) of the second peripheral component, thereby controlling the relevant function operation of the second peripheral component.

[0049] Through the SNMP-based communication connection, the second peripheral components (especially the peripheral components with Ethernet interfaces) of the medical imaging system can be managed uniformly by the host computer. In addition, the SNMP-based communication can reduce the amount of signaling sent and received between the host computer and the second peripheral components to reduce the possibility of channel congestion, thereby reducing the communication delay between the host computer and the second peripheral components.

[0050] According to some embodiments, the second peripheral component may maintain a management information base, the management information base defines at least one managed object of the second peripheral component that can be managed by the host 110, and the host 110 maintains a peripheral device repository, the peripheral device repository includes a mapping of at least one managed object in the management information base. And the function operation instruction module 240 may be further configured to: based on the mapping relationship between the peripheral device repository and the management information base, send a function operation instruction to the second peripheral component to control a first managed object of at least one managed object of the second peripheral component to perform a function operation.

[0051] In the example, the management information base can define the state, detailed information and specific configuration of at least one managed object of the second peripheral component that can be managed by the main control machine 110. For example, the management information base can define the volume of the speaker or microphone of the voice intercom, thereby allowing the main control machine 110 to manage the speaker or microphone. Accordingly, the main control machine 110 maintains a peripheral device repository, and the peripheral device repository includes a mapping of at least one managed object in the management information base, so that the peripheral device repository can have a structure similar to the management information base. In the example, this mapping relationship can be indicated between the management information base and the peripheral device repository through an object identifier, thereby allowing the main control machine 110 to control different managed objects of the second peripheral component separately.

[0052] Figure 3 FIG. 1 shows a structural block diagram of either a main console 111 or a scanning and reconstruction system 112 of a medical imaging system according to another embodiment of the present disclosure. Figure 3 As shown, the console 111 or the scanning and reconstruction system 112 may include an IP address allocation module 310, a reset indication module 320, a reset information receiving module 330 and a function operation indication module 340. Modules 310 to 340 are respectively related to the above Figure 2 The modules 210 to 240 described are similar and will not be described again here.

[0053] In some scenarios (e.g., when upgrading the software or firmware of the second peripheral component), the version of the second peripheral component may be inconsistent with the firmware version for the second peripheral component maintained on the host computer, which may cause the host computer to be unable to correctly control the second peripheral component or cause a program error in the process of controlling the second peripheral component.

[0054] According to some embodiments, continue to refer to Figure 3 Either the main console 111 or the scanning and reconstruction system 112 may further include a firmware version checking module 350, which is configured to: obtain first version information of the current firmware of the second peripheral component from the second peripheral component before the functional operation indication module 340 sends a functional operation instruction to the second peripheral component; compare the first version information with second version information of the firmware for the second peripheral component maintained by the main control machine; and in response to determining that the first version information is different from the second version information, send the second version of firmware data to the second peripheral component, so that the second peripheral component can perform a firmware update based on the received second version of firmware data.

[0055] Therefore, before the functional operation indication module 340 sends a functional operation instruction to the second peripheral component, by checking and updating the firmware version of the second peripheral component, it can be ensured that the firmware version of the second peripheral component is consistent or synchronized with that of the main control computer, so that the main control computer can smoothly control the subsequent functional operations of the second peripheral component.

[0056] In the example, the second version of firmware data with a larger capacity can be sent to the second peripheral component based on the file transfer protocol FTP or the simple file transfer protocol TFTP. Among them, FTP is based on the transmission control protocol TCP. When performing file transfer, two parallel TCP connections, namely the control connection and the data connection, can be established between the host and the second peripheral device. The control connection remains open during the entire session, and the data transfer request is sent through the control connection, while the file is sent through the data connection. TFTP is based on the user datagram protocol UDP, so the host can transmit the second version of firmware data to multiple second peripheral components at the same time.

[0057] According to some embodiments, further reference is made to Figure 3 Either the main control machine console 111 or the scanning and reconstruction system 112 may further include an initialization module 360, which is configured to: before the functional operation instruction module 340 sends a functional operation instruction to the second peripheral component, send an initialization instruction to the second peripheral component so that the second peripheral component resets at least one operating parameter of the second peripheral component to an initial value.

[0058] In the example, the initialization instruction may instruct the second peripheral component to initialize parameters related to the component state, or may set important operating parameters to default values. For example, the second peripheral component may be a camera that is connected to the host computer 110 through a simple network management protocol SNMP, and the initialization instruction may instruct the camera to initialize its internal parameters.

[0059] According to some embodiments, continue to refer to Figure 3 Either the console 111 or the scanning and reconstruction system 112 may further include an asset management information acquisition module 370 configured to: acquire asset management information of the second peripheral component from the second peripheral component, the asset management information including at least one of the serial number of the second peripheral component and the program version running by the second peripheral component. In an example, the serial number of the second peripheral component may include at least one of the material number, serial number, or hardware version number of the second peripheral component.

[0060] Therefore, the main control machine 110 can timely obtain the asset management information of the second peripheral component, and thus record the asset management information of the second peripheral component, so as to facilitate intergenerational management, tracking and maintenance of the second peripheral component.

[0061] According to some embodiments, the medical imaging system 100 may be a magnetic resonance system, and the console 111 may include a magnetic resonance console.

[0062] Figure 4 A structural block diagram of a peripheral component 400 of a medical imaging system according to an embodiment of the present disclosure is shown.

[0063] like Figure 4 As shown, the peripheral component 400 includes:

[0064] The IP address acquisition module 410 is configured to send an Internet Protocol IP address request to the host computer;

[0065] A reset module 420, configured to, in response to receiving a reset instruction from the host control machine, restart the program and send information to the host control machine indicating that the peripheral component has completed the program restart; and

[0066] The function operation module 430 is configured to perform a function operation in response to receiving a function operation instruction from the host control machine.

[0067] After the peripheral component 400 obtains the corresponding IP address, it can communicate with the host computer based on the IP address.

[0068] In an example, the peripheral component 400 can set the high and low levels of its general purpose input / output port (GPIO) according to the received functional operation instruction, so as to perform the relevant functional operation.

[0069] Thus, through the communication connection based on SNMP, the unified management of the peripheral components of the medical imaging system (especially the peripheral components with Ethernet interface) can be realized through the main control machine. Moreover, the communication based on SNMP can reduce the amount of signaling sent and received between the main control machine and the peripheral components to reduce the possibility of channel congestion, thereby reducing the communication delay between the main control machine and the peripheral components. In addition, before the peripheral component 400 performs the functional operation, by restarting its program, it can effectively avoid the occurrence of errors caused by internal errors of the peripheral component 400 or the incoordination of the operating state of the peripheral component 400 and the main control machine. This is particularly advantageous in the process of performing medical imaging examinations. In the example, the peripheral component 400 can use trap information to directly send information indicating that the peripheral component has completed the program restart to the main control machine.

[0070] Figure 5 FIG. 5 shows a structural block diagram of a peripheral component 500 of a medical imaging system according to another embodiment of the present disclosure.

[0071] like Figure 5 As shown, the peripheral component 500 includes an IP address acquisition module 510, a reset module 520 and a function operation module 530. Modules 510 to 530 are respectively the same as those described above. Figure 4 The modules 410 to 430 described are similar and will not be described again here.

[0072] According to some embodiments, continue to refer to Figure 5 The peripheral component 500 may further include a status monitoring module 540 configured to send status change information to the host control machine based on SNMP in response to detecting a change in the status of the peripheral component 500.

[0073] In an example, when the peripheral component 500 detects an event, the threshold value of the event can be checked. The agent program running in the peripheral component 500 can report events reaching certain threshold values ​​to the management process of the host through trap information. These events exceeding the threshold values ​​can be considered to indicate that a state change has occurred in the peripheral component 500. In this way, only when a more serious event occurs can it be reported to the host.

[0074] According to some embodiments, the peripheral component may include one of the following: a camera, a camcorder, a touchpad, or a voice intercom.

[0075] The following will be combined Figure 6 The main control computer and peripheral devices of the medical imaging system according to the embodiment of the present disclosure are further described. Figure 6 A system framework diagram of a medical imaging system according to an embodiment of the present disclosure is shown.

[0076] like Figure 6 As shown, the architecture of the main control machine includes a user application 610 (e.g., an operating program of the main control machine), control software 620, a peripheral device storage library 630, and a first SNMP basic library 640. And the architecture of the peripheral components includes SNMP agent software 650, hardware 660, a second SNMP basic library 670, and a management information library 680. Among them, the first SNMP basic library 640 and the second SNMP basic library 670 both store SNMP basic library functions, and the SNMP basic library functions can come from an open source library.

[0077] Continue to refer Figure 6 The main control machine is connected to the peripheral components based on SNMP. The control software 620 includes a user end 621, a service end 622 and a hardware access module 623, wherein the user end 621 is responsible for processing the call instruction from the user application 610, and the hardware access module 623 is responsible for calling the first SNMP basic library 640 to operate the SNMP basic library function and receive the trap information from the peripheral components. Correspondingly, the SNMP agent software 650 can also call the second SNMP basic library 670.

[0078] In addition, the main control machine can send functional operation instructions to the peripheral components based on the mapping relationship between the peripheral device repository 630 and the management information library 680 to control the specific hardware 660 of the peripheral components (such as a camera, a camcorder, a touchpad or a voice intercom) to perform corresponding functional operations (such as setting the shooting parameters of the camera, the volume of the voice intercom, etc.).

[0079] According to another aspect of the present disclosure, a method for a medical imaging system is provided.

[0080] Figure 7 A flowchart of a method 700 for a medical imaging system according to an embodiment of the present disclosure is shown.

[0081] The medical imaging system includes a host computer and peripheral components that are connected to the host computer through a simple network management protocol (SNMP). The method 700 is executed by the host computer and includes:

[0082] Step S710, in response to receiving an Internet Protocol IP address request from a peripheral component, allocating an IP address to the peripheral component;

[0083] Step S720: in response to the main control machine being turned on or restarted, a reset instruction is sent to the peripheral component based on the IP address and SNMP, so that the peripheral component restarts the program;

[0084] Step S730 receives information from the peripheral component indicating that the peripheral component has completed program restart; and

[0085] Step S740 sends a function operation instruction to the peripheral component based on the IP address and SNMP in response to receiving the information to control the function operation of the peripheral component.

[0086] Thus, through the SNMP-based communication connection, the unified management of the peripheral components of the medical imaging system (especially the peripheral components with Ethernet interfaces) can be achieved through the host computer. Moreover, the SNMP-based communication can reduce the amount of signaling sent and received between the host computer and the peripheral components to reduce the possibility of channel congestion, thereby reducing the communication delay between the host computer and the peripheral components. In addition, the occurrence of errors caused by internal errors of the peripheral components or the incoordination of the operating status of the peripheral components and the host computer can be effectively avoided. This is particularly advantageous in the process of medical imaging examination.

[0087] The following will be combined Figure 8 The method for a medical imaging system according to an embodiment of the present disclosure is further described. Figure 8 A process diagram of a method for a medical imaging system according to an embodiment of the present disclosure is shown.

[0088] like Figure 8As shown, the main control machine 820 and the peripheral component 830 are connected based on SNMP communication. In step S801, the peripheral component 830 can send an Internet Protocol IP address request to the main control machine 820. In step S802, the main control machine 820 allocates an IP address to the peripheral component 830 in response to receiving the Internet Protocol IP address request from the peripheral component 830. In step S803, in response to the main control machine 820 starting or restarting, based on the IP address and SNMP, the main control machine 820 sends a reset instruction to the peripheral component 830, so that the peripheral component 830 restarts the program in step S804. In step S805, when the peripheral component 830 completes the program restart, the peripheral component 830 sends information to the main control machine 820 indicating that the peripheral component 830 has completed the program restart. In step S806, the main control machine 820 can request and obtain the first version information of the current firmware of the peripheral component 830 from the peripheral component 830. Subsequently, the main control machine 820 compares the first version information with the second version information of the firmware for the peripheral component 830 maintained by the main control machine 820 in step S807. When the main control machine 820 determines that the first version information is different from the second version information, the main control machine 820 sends the second version of the firmware data to the peripheral component 830 in step S808, so that the peripheral component 830 can perform a firmware update based on the received second version of the firmware data. After checking the firmware version of the peripheral component 830 and completing the firmware update, in step S809, the main control machine 820 sends an initialization instruction to the peripheral component 830, so that the peripheral component 830 resets at least one operating parameter of the peripheral component 830 to an initial value in step S810. In step S811, the main control machine 820 can obtain the asset management information of the peripheral component 830 from the peripheral component 830 based on the SNMP request. In addition, when the peripheral component 830 detects that its state has changed, it can send state change information to the main control machine 820 based on SNMP in step S812. In step S813 , the host control machine 820 may send a function operation instruction to the peripheral component 830 to control the peripheral component 830 to perform a function operation in step S814 .

[0089] In some examples, after the peripheral component 830 sends the first version information of the current firmware of the peripheral component 830 to the main control machine 820, the peripheral component 830 can automatically start a program for updating its firmware, and can send information to the main control machine 820 after completing the firmware update (for example, executing step S805). After that, the main control machine 820 may further perform steps similar to the steps S806 to S808 described above, that is, the main control machine 820 may request and obtain the version information of the currently updated firmware of the peripheral component 830 from the peripheral component 830, and then compare the updated version information with the second version information of the firmware for the peripheral component 830 maintained by the main control machine 820. When the main control machine 820 determines that the version information of the updated firmware is the same as the second version information, it is considered that the peripheral component 830 has successfully downloaded the firmware; when the main control machine 820 determines that the version information of the updated firmware is different from the second version information, the main control machine 820 may directly report the error indication information of the firmware download failure, or send the second version of the firmware data to the peripheral component 830 again, so that the peripheral component 830 can perform the firmware update again based on the received second version of the firmware data. In this example, the number of attempts for firmware upgrade may be limited.
