Specific Embodiments

[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0030] In modern medical imaging systems (such as MRI (Nuclear Magnetic Resonance Imaging) systems, CT (Computed Tomography) systems, etc.), it is usually necessary for the host computer and the recon computer to work together. The host computer is responsible for providing a user interface, setting scanning parameters, and displaying imaging results, etc.; the recon computer is responsible for processing a large amount of data, performing image reconstruction and processing, etc.

[0031] To improve the working efficiency and operation convenience of the system, it is usually desired that the host computer and the recon computer can achieve synchronous power-on and power-off. In related technologies, a synchronous operation method between the host computer and the recon computer is proposed. Mainly, control cards are respectively inserted into the respective PCI (Peripheral Component Interconnect) or PCIe (Peripheral Component Interconnect Express) slots of the host computer and the recon computer to monitor the power signal and reset signal of each computer, and the control cards are connected by a cable. The control card also includes a relay switch. The control card simulates pressing the power switch button of the computer manually by controlling the closing of the relay switch on it, so as to realize the power-on, power-off, and restart control of the computer.

[0032] However, the above synchronous control scheme is mainly for the synchronous control between one host computer and one recon computer, and it has the following disadvantages:

[0033] (1) Insufficient PCIe slot resources: An imaging card is usually installed inside the recon computer, and all PCIe slots may be occupied due to the installation of the imaging card in the recon computer, resulting in the inability to insert the control card for power-on / off synchronization control, making the synchronous control scheme inapplicable.

[0034] (2) Insufficient multi-device support: Facing the scenario where one host computer needs to synchronously control multiple recon computers, in the above scheme, the control cards of multiple recon computers need to be connected in series, with a high hardware connection complexity, low communication reliability, and being difficult to manage, making it difficult to meet the reliability requirements for supporting multi-device synchronous control.

[0035] (3) Communication distance limitation: When the distance between the master console computer and the image reconstruction computer is relatively long (for example, the master console computer and the image reconstruction computer are located in different computer rooms), the above synchronization control method connects the control card in the master console computer and the control card in the image reconstruction computer by means of a cable connection. The control cards communicate with simple level signals, which have deficiencies in signal transmission and reliability and cannot meet the signal transmission requirements when the distance between the master console computer and the image reconstruction computer is relatively long.

[0036] (4) Lack of flexibility and scalability: When the equipment is upgraded or expanded, the above synchronization control method does not have sufficient flexibility and cannot adapt to different system configurations.

[0037] In the related art, some solutions for computer synchronization control have also been proposed, such as the solution for synchronization control through Wake-on-LAN (WOL) technology and the solution for synchronization control through a host management controller (BMC (Baseboard Management Controller, baseboard management controller) or IPMI (Intelligent Platform Management Interface, intelligent platform management interface)). Among them, the Wake-on-LAN technology sends specific data packets to the computer through the network to achieve remote power-on and power-off. However, this method depends on the network, and its reliability is affected by the network condition, and it cannot be controlled in the case of power failure or system crash. The host management controller realizes remote power management through an independent management controller, but it requires computer hardware support, which increases the cost and cannot be applied to all systems.

[0038] In order to solve the problem that the insufficient PCIe slot resources of the image reconstruction computer greatly limit the implementation of the synchronization control solution and result in low compatibility of the synchronization control solution, it is necessary to provide a medical imaging system. The medical imaging system provided in this specification includes a master control end, an image reconstruction end, and an image reconstruction end synchronization control module. Among them, the image reconstruction end synchronization control module is communicatively connected to the master control end. The image reconstruction end is connected to the image reconstruction end synchronization control module through a peripheral interface and a switch signal line, so that the image reconstruction end synchronization control module is external to the image reconstruction end and does not need to occupy the internal PCIe slot of the image reconstruction end.

[0039] The image reconstruction end synchronization control module can obtain the status of the connected image reconstruction end through the peripheral interface. Specifically, in some implementable ways, if the image reconstruction end synchronization control module obtains the power signal and reset signal of the image reconstruction end through the peripheral interface, it can determine that the image reconstruction end is in the shutdown state or the restart state according to the power signal and reset signal; if it does not obtain the power signal and reset signal of the image reconstruction end through the peripheral interface, it can determine that the image reconstruction end is in the shutdown state.

[0040] When the states of the image building end and the master control end are not synchronized, the image building end synchronization control module can generate a power switch signal to simulate the signal generated by manually pressing the computer power button, and send it to the image building end through the switch signal line to control the image building end to adjust its state. For example, if the image building end is currently in the shutdown state, the image building end synchronization control module can control the image building end to power on through the power switch signal; if the image building end is currently in the power-on state, the image building end synchronization control module can control the image building end to power off through the power switch signal, and so on. In this way, the state of the image building end is adjusted to be consistent with the state of the master control end.

[0041] Therefore, by externalizing the image building end synchronization control module, it is avoided to occupy the PCIe slot of the image building end, and the dependence of the image building end synchronization control module on the hardware resources of the image building end is reduced; the externalized image building end synchronization control module obtains the power signal and reset signal of the image building end through the peripheral interface to solve the problem that the external control module cannot obtain signals; the power switch signal generated by the externalized image building end synchronization control module is used to simulate the signal generated by manually pressing the power switch of the image building end, and the power switch signal generated outside the image building end is transmitted through the external plug (switch signal line) to realize the on-off control of the image building end. Through the peripheral interface and the switch signal line, reliable control of the image building end by the externalized image building end synchronization control module is realized, the reliable on-off synchronization requirement between the master control end and the image building end is met, and the compatibility and scalability of the synchronization control scheme between the master control end and the image building end can be effectively improved.

[0042] In addition, in some embodiments, the master control end and the image building end synchronization control module are connected through a serial communication link. In the related art, the multi-camera control method based on the network is easily affected by the network communication state. In the case of network interruption, the master control end cannot control the states of multiple cameras. At the same time, in the multi-camera control method based on the network, the master control end can only control the cameras after establishing a network connection with multiple cameras, and the state control of the master control end and multiple cameras is not synchronized. In this application, the image building end synchronization control module identifies the state of the image building end. When the states of the master control end and the image building end are inconsistent, the image building end is controlled through the switch signal line, which can ensure the synchronous control of the master control end and the camera and is not affected by the network communication state.

[0043] The embodiments of this specification provide a medical imaging system. Refer to Figure 1a or Figure 1b As shown, the medical imaging system 100 includes a master control end 110, an image building end 120, and an image building end synchronization control module 130; the image building end 120 is connected to the image building end synchronization control module 130 through a peripheral interface and a switch signal line. The image building end synchronization control module 130 is communicatively connected to the master control end 110.

[0044] The image - building end synchronization control module 130 is used to obtain the status of the image - building end 120 through a peripheral interface. When the status of the image - building end 120 is not synchronized with the status of the main control end 110, it sends a power - switch signal to the image - building end 120 through a switch signal line to adjust the status of the image - building end 120 to be synchronized with the status of the main control end 110.

[0045] Among them, the main control end 110 can be a main control console computer, a console device, or a console terminal, which is mainly responsible for providing a user interface, setting scanning parameters, and displaying imaging results, etc.

[0046] The image - building end 120 can be an image - building computer, an image - building machine, an image - building device, or an image - building terminal, which is mainly responsible for processing a large amount of data, performing image reconstruction and processing, etc.

[0047] The status of the image - building end 120 and the status of the main control end 110 both include a power - on state, a power - off state, and a restart state.

[0048] The image - building end synchronization control module 130 has the function of controlling the status of the image - building end 120 to be consistent with the status of the main control end 110. There is a communication connection between the image - building end synchronization control module 130 and the main control end 110, and data interaction can be carried out.

[0049] The peripheral interface is a physical interface used to connect a computer or other main control device to an external device. It is a channel for providing data transmission, signal exchange, device control, power supply, etc., enabling different types of external devices to interact with the host system.

[0050] The switch signal line is a cable used to transmit control signals.

[0051] The power - switch signal is an electrical signal used to control the power state of the image - building end 120, which is generated by the image - building end synchronization control module 130.

[0052] Specifically, the medical imaging system 100 provided in this specification includes a main control end 110, an image - building end 120, and an image - building end synchronization control module 130 connected to the image - building end 120 through a peripheral interface and a switch signal line. The image - building end synchronization control module 130 is externally placed with respect to the image - building end 120. In some implementable ways, continue to refer to Figure 1a As shown, the image - building end synchronization control module 130 can be an independent module externally placed with respect to the main control end 110 and the image - building end 120; or, in some other implementable ways, continue to refer to Figure 1b As shown, the image - building end synchronization control module 130 can also be a module included in the main control end 110. Then, the communication connection between the image - building end synchronization control module 130 and the main control end 110 means that there is data transfer, message sending, or interface call between the image - building end synchronization control module 130 and the main control end 110.

[0053] The image - building end synchronization control module 130 can monitor the status of the image - building end 120 through the peripheral interface. The image - building end synchronization control module 130 can also obtain the status of the master control end 110. When the image - building end synchronization control module 130 detects that the status of the image - building end 120 is not synchronized with the status of the master control end 110, it can generate a power switch signal and send the power switch signal to the image - building end 120 through the switch signal line to adjust the status of the image - building end 120 to be synchronized with the status of the master control end 110. Among them, the status of the image - building end 120 not being synchronized with the status of the master control end 110 can include that the master control end 110 is in the shutdown state or restart state while the image - building end 120 is in the startup state, the master control end 110 is in the startup state while the image - building end 120 is in the shutdown state, etc.

[0054] Exemplarily, if the image - building end synchronization control module 130 detects that the master control end 110 is in the startup state and the image - building end 120 is in the shutdown state, the image - building end synchronization control module 130 can generate a power switch signal to simulate the signal generated by manually pressing the power button of the image - building end 120. Since the imaging device is in the shutdown state, pressing the power button will cause the image - building end 120 to start up. Therefore, at this time, the power switch signal can control the image - building end 120 to change from the shutdown state to the startup state.

[0055] If the image - building end synchronization control module 130 detects that the master control end 110 is in the shutdown state and the image - building end 120 is in the startup state, the image - building end synchronization control module 130 can generate a power switch signal to simulate the signal generated by manually pressing the power button of the image - building end 120. Since the imaging device is in the startup state, pressing the power button will cause the image - building end 120 to shut down. Therefore, at this time, the power switch signal can control the image - building end 120 to change from the startup state to the shutdown state.

[0056] If the image - building end synchronization control module 130 detects that the master control end 110 is in the restart state and the image - building end 120 is in the startup state, the image - building end synchronization control module 130 can generate a power switch signal to simulate the signal generated by manually pressing the power button of the image - building end 120 twice in a short time. Since the imaging device is in the startup state, pressing the power button for the first time will cause the image - building end 120 to shut down, and pressing the power button again in the shutdown state will cause the image - building end 120 to start up again. Therefore, at this time, the power switch signal can control the image - building end 120 to change from the startup state to the restart state.

[0057] In some embodiments, the process by which the imaging end synchronization control module 130 obtains the status of the imaging end 120 through the peripheral interface may specifically include: If the imaging end synchronization control module 130 obtains the first power signal and the first reset signal of the imaging end 120 through the peripheral interface, it is determined that the imaging end 120 is in the power-on state or the restart state; If the imaging end synchronization control module 130 does not obtain the first power signal and the first reset signal through the peripheral interface, it is determined that the imaging end 120 is in the power-off state.

[0058] The process by which the imaging end synchronization control module 130 determines the power-on state, power-off state, or restart state of the master control end 110 may specifically include: If the imaging end synchronization control module 130 obtains the second power signal and the second reset signal of the master control end 110, it determines the power-on state or the reset state of the master control end 110 according to the second power signal and the second reset signal; If the imaging end synchronization control module 130 does not obtain the second power signal and the second reset signal, it is determined that the master control end 110 is in the power-off state.

[0059] Further, if the imaging end synchronization control module 130 does not obtain the second power signal and the second reset signal and determines that the master control end 110 is in the power-off state, it may include: If the imaging end synchronization control module 130 does not obtain the second power signal and the second reset signal within the first preset time threshold, it is determined that the master control end 110 is in the power-off state. If the imaging end synchronization control module 130 does not obtain the first power signal and the first reset signal through the peripheral interface and determines that the imaging end 120 is in the power-off state, it may include: If the imaging end synchronization control module 130 does not obtain the first power signal and the first reset signal within the second preset time threshold, it is determined that the imaging end 120 is in the power-off state.

[0060] Specifically, when the master control end 110 is in the power-on state or other normal working states, the imaging end synchronization control module 130 can continuously obtain the second power signal and the second reset signal. To avoid misjudgment by the imaging end synchronization control module 130 on whether the master control end 110 is in the power-off state due to signal transmission delay, short-term interference, etc., a first preset time threshold is set. If the imaging end synchronization control module 130 does not obtain the second power signal and the second reset signal of the master control end 110 within the first preset time threshold, it is determined that the master control end 110 is in the power-off state. Similarly, a second preset time threshold is set. If the imaging end synchronization control module 130 does not obtain the first power signal and the first reset signal of the imaging end 120 within the second preset time threshold, it is determined that the imaging end 120 is in the power-off state.

[0061] Exemplarily, both the first preset time threshold and the second preset time threshold are set to 5 seconds. If the image acquisition end synchronization control module 130 fails to obtain the second power signal and the second reset signal of the master control end 110 within 5 seconds, it is determined that the master control end 110 is in the shutdown state. Similarly, if the image acquisition end synchronization control module 130 fails to obtain the first power signal and the first reset signal of the image acquisition end 120 within 5 seconds, it is determined that the image acquisition end 120 is in the shutdown state.

[0062] Exemplarily, the first preset time threshold is set to 4 seconds, and the second preset time threshold is set to 3 seconds. If the image acquisition end synchronization control module 130 fails to obtain the second power signal and the second reset signal of the master control end 110 within 4 seconds, it is determined that the master control end 110 is in the shutdown state. If the image acquisition end synchronization control module 130 fails to obtain the first power signal and the first reset signal of the image acquisition end 120 within 3 seconds, it is determined that the image acquisition end 120 is in the shutdown state.

[0063] It should be noted that the first power signal and the first reset signal can be sent to the image acquisition end synchronization control module 130 by the synchronization operation software of the image acquisition end 120 through the peripheral interface, or can be generated by the relevant hardware circuit of the image acquisition end 120 and then sent to the image acquisition end synchronization control module 130 through the peripheral interface. Similarly, the second power signal and the second reset signal can be sent to the image acquisition end synchronization control module 130 by the synchronization operation software of the master control end 110, or can be sent to the image acquisition end synchronization control module 130 by the master control end synchronization control module in the master control end 120.

[0064] The first preset time threshold and the second preset time threshold can be specifically determined according to the actual application scenario and requirements, etc., and the first preset time threshold and the second preset time threshold can be the same or different, which is not specifically limited in this specification.

[0065] In some other embodiments, the master control end 110 may include synchronization operation software, and the synchronization operation software may send the status information of the master control end 110 to the image acquisition end synchronization control module 130 through relevant instructions, so that the image acquisition end synchronization control module 130 determines the status of the master control end 110 through instruction parsing. The image acquisition end 120 may also include synchronization operation software to send the status information of the image acquisition end 120 to the image acquisition end synchronization control module 130 through the peripheral interface.

[0066] It should be noted that the method by which the above image-forming end synchronization control module 130 determines the state of the image-forming end 120 based on the first power signal and the first reset signal, and the method by which the image-forming end synchronization control module 130 determines the state of the main control end 110 based on the second power signal and the second reset signal can be determined according to specific circuit designs and system logics, and are not specifically limited in this specification. For example, if it is designed that a high-level power signal indicates power-on, a low-level power signal indicates power-off, and a high-level reset signal indicates restart, then when the image-forming end synchronization control module 130 obtains the first power signal and the first reset signal, and the first power signal is high-level and the first reset signal is low-level, it can be determined that the image-forming end 120 is in the power-on state. If the first power signal is high-level and the first reset signal is high-level, it can be determined that the image-forming end 120 is in the restart state.

[0067] If it is designed that a low-level power signal indicates power-on, a high-level power signal indicates power-off, and a high-level reset signal indicates restart, then when the first power signal is low-level and the first reset signal is low-level, it can be determined that the image-forming end 120 is in the power-on state; if the first power signal is low-level and the first reset signal is high-level, it can be determined that the image-forming end 120 is in the restart state.

[0068] If it is designed that a high-level power signal indicates power-on, a low-level power signal indicates power-off, and a low-level reset signal indicates restart, then when the first power signal is high-level and the first reset signal is high-level, it can be determined that the image-forming end 120 is in the power-on state; if the first power signal is high-level and the first reset signal is low-level, it can be determined that the image-forming end 120 is in the restart state.

[0069] If it is designed that a low-level power signal indicates power-on, a high-level power signal indicates power-off, and a low-level reset signal indicates restart, then when the first power signal is low-level and the first reset signal is high-level, it can be determined that the image-forming end 120 is in the power-on state; if the first power signal is low-level and the first reset signal is low-level, it can be determined that the image-forming end 120 is in the restart state.

[0070] In this specification, the image-forming end synchronization control module 130 can be an integrated circuit board for computer synchronization operations, such as STTR (Synchronized Turn on / Turn off card of Recon, image-forming machine synchronization power-on / off card), etc., or any one of programmable logic devices, microcontrollers, etc. for computer synchronization operations, and are not specifically limited in this specification.

[0071] The master control terminal 110 can obtain the status information of the imaging terminal 120 through the imaging terminal synchronization control module 130, and when the status of the imaging terminal 120 is not synchronized with the status of the master control terminal 110, send a control instruction to the imaging terminal synchronization control module 130 to instruct the imaging terminal synchronization control module 130 to adjust the status of the imaging terminal 120. Then, the imaging terminal synchronization control module 130 can specifically be further configured to obtain the control instruction sent by the master control terminal 110, and when the status of the imaging terminal 120 is not synchronized with the status of the master control terminal 110, send a power switch signal to the imaging terminal 120 according to the control instruction to adjust the status of the imaging terminal 120 to be synchronized with the status of the master control terminal 110.

[0072] In this specification, the imaging terminal synchronization control module 130 can be powered by a power source other than the imaging terminal 120. When the imaging terminal 120 is in the powered-on state, the imaging terminal 120 can supply power to the imaging terminal synchronization control module 130 through a peripheral interface; when the imaging terminal 120 is in the powered-off state, the imaging terminal synchronization control module 130 can be powered by other power sources. The peripheral interface can be any one of a USB (Universal Serial Bus) interface, an SPI (Serial Peripheral Interface), an IIC (Inter-Integrated Circuit) interface, etc.

[0073] In the above embodiments, by externally disposing the imaging terminal synchronization control module outside the imaging terminal, the imaging terminal synchronization control module obtains the power signal and reset signal of the imaging terminal through the peripheral interface, avoiding occupying the PCIe slot resources of the imaging terminal, and solving the problem that the externally disposed control module cannot obtain signals, enabling the imaging terminal synchronization control module to reliably monitor and control the status of the imaging terminal, and improving the feasibility of the synchronization control scheme in the medical imaging system. The externally disposed imaging terminal synchronization control module is also connected to the imaging terminal through an externally connected switch signal line to transmit the power switch signal generated by the imaging terminal synchronization control module to the imaging terminal through the switch signal line, realizing the on / off control of the imaging terminal. Among them, the power switch signal is used to simulate the signal generated by manually pressing the power switch of the imaging terminal. Through the peripheral interface and the switch signal line, the externally disposed imaging terminal synchronization control module can reliably control the imaging terminal, meet the on / off synchronization requirement between the master control terminal and the imaging terminal, and effectively improve the compatibility and scalability of the synchronization control scheme.

[0074] In some embodiments, the imaging terminal synchronization control module 130 includes a central control module and a switch module, and the central control module is configured to control the switch module to switch to a conducting state to generate a power switch signal.

[0075] Among them, the central control module is the core part of the image building end synchronization control module 130, which can have functions such as data processing, logical judgment, and control, and can detect and control the signals, states, etc. of the image building end 120.

[0076] The switch module has a conducting state and a disconnecting state, and generates a power switch signal through state switching. When the switch module is in the conducting state, it is equivalent to closing the circuit (i.e., equivalent to the switch being closed), thereby generating a power switch signal; when the switch module is in the disconnecting state, it is equivalent to opening the circuit (i.e., equivalent to the switch being open), and the power switch signal disappears.

[0077] Specifically, when the central control module in the image building end synchronization control module 130 detects that the state of the image building end 120 is not synchronized with the state of the main control end 110, it can generate a corresponding control signal according to the specific situation and send it to the switch module. Under the action of the control signal, the switch module switches from the disconnecting state to the conducting state to generate a power switch signal.

[0078] It can be understood that the central control module can also control the duration of the conducting state of the switch module.

[0079] In some embodiments, the switch module can be a relay module. When the contacts of the relay module are closed, it means that the relay module is in the conducting state, and the power switch signal is generated by the central control module controlling the closing of the contacts of the relay module.

[0080] Exemplarily, if the central control module detects that the main control end 110 is in the power-on state and the image building end 120 is in the power-off state, the central control module can control the contacts of the relay module to close for a short time to generate a power switch signal, which is used to simulate the signal generated by manually pressing the power button of the image building end 120 for a short time to control the image building end 120 to adjust from the power-off state to the power-on state.

[0081] If the central control module detects that the main control end 110 is in the power-off state and the image building end 120 is in the power-on state, the central control module can control the contacts of the relay module to close for a short time to generate a power switch signal, which is used to simulate the signal generated by manually pressing the power button of the image building end 120 for a short time to control the image building end 120 to adjust from the power-on state to the power-off state.

[0082] If the central control module detects that the master control end 110 is in a restart state and the image building end 120 is in a powered-on state, the central control module can control the contact of the relay module to close for a short time to generate a signal for simulating the signal generated by manually pressing the power button of the image building end 120 for a short time, and control the image building end 120 to adjust from the powered-on state to the powered-off state. Then, in the powered-off state, the central control module can control the contact of the relay module to close for a short time again to generate a signal for simulating the signal generated by manually pressing the power button of the image building end 120 for a short time, and control the image building end 120 to readjust from the powered-off state to the powered-on state, realizing the restart of the image building end 120. The power switch signal can include the signals generated by these two contacts closing. When the image building end synchronization control module 130 detects that the image building end 120 adjusts from the powered-on state to the powered-off state and then to the powered-on state within a short time, the image building end synchronization control module 130 can consider that the image building end 120 is in a restart state.

[0083] It should be noted that the switch module can also be any one of a transistor module, a field effect transistor module, an optocoupler device, etc., which is not specifically limited in this specification. Taking the transistor module as an example, specifically taking the bipolar transistor as an example, when a current path is formed between the collector and the emitter of the bipolar transistor, it means that the bipolar transistor is in a conducting state, and the power switch signal is generated by the central control module controlling the current conduction between the collector and the emitter of the bipolar transistor. Regarding the description of the central control module controlling the state of the field effect transistor module or the optocoupler device to switch to the conducting state, reference can be made to the description in the related art, which will not be elaborated here specifically.

[0084] The central control module can be an FPGA (Field Programmable Gate Array), or an MCU (Microcontroller Unit), or an MPU (Microprocessor Unit), etc., which is not specifically limited in this specification.

[0085] In some embodiments, the central control module is further configured to control the state of the switch module to switch to the conducting state when the synchronization between the state of the image building end 120 and the state of the master control end 110 fails, and a power switch signal is generated when the duration of the conducting state reaches a preset duration.

[0086] Among them, the image building end synchronization control module 130 adjusts the state of the image building end 120 to the powered-off state, that is, the central control module adjusts the state of the image building end 120 to the powered-off state by controlling the switch module.

[0087] Specifically, when the central control module in the imaging end synchronization control module 130 detects that the master control end 110 is in the shutdown state and the imaging end 120 is in the startup state, and it is necessary to control the imaging end 120 to shut down, the central control module controls the state of the switch module to switch to the conducting state to control the imaging end 120 to adjust to the shutdown state. In the case where the imaging end 120 fails to shut down and the central control module detects that the state of the imaging end 120 has not been successfully adjusted to the shutdown state (that is, the state synchronization between the imaging end 120 and the master control end 110 fails), the central control module can control the state of the switch module to switch to the conducting state, and the duration of the conducting state reaches a preset duration. Thereby generating a corresponding power switch signal to simulate the signal generated by manually long-pressing the power button of the imaging end 120 to control the imaging end 120 to force shutdown.

[0088] It can be understood that when the imaging end 120 is in the startup state, the imaging end synchronization control module 130 or the central control module can obtain the power signal and reset signal of the imaging end 120 at regular intervals. Thus, the imaging end synchronization control module 130 or the central control module can detect the state of the imaging end 120.

[0089] It should be noted that the preset duration can be determined according to actual application requirements, etc., and is not specifically limited in this specification.

[0090] In some embodiments, as shown in Figure 2a the master control end 110 includes a master control end synchronization control module 210, and the master control end synchronization control module 210 is connected to the imaging end synchronization control module 130 through a remote communication link.

[0091] Among them, the master control end synchronization control module 210 can obtain the power signal, reset signal, button signal, etc. of the master control end 110, and can communicate and interact with the imaging end synchronization control module 130.

[0092] Specifically, the master control end 110 includes a master control end synchronization control module 210, and the master control end synchronization control module 210 is connected to the imaging end synchronization control module 130 through a remote communication link. To ensure the accuracy of synchronization control, in the remote communication protocol used for communication between the master control end synchronization control module 210 and the imaging end synchronization control module 130, the power indication signal and reset signal status of the master control end 110 and the imaging end 120 are added.

[0093] Through the remote communication link, the master control end synchronization control module 210 and the image building end synchronization control module 130 can conduct information interaction. The master control end synchronization control module 210 can send relevant status information of the master control end 110 (including power signal, reset signal, etc.), control instructions, etc. to the image building end synchronization control module 130. The image building end synchronization control module 130 adjusts the status of the image building end 120 according to the received information to achieve synchronization with the status of the master control end 110. The image building end synchronization control module 130 can also feedback the status information of the image building end 120 to the master control end synchronization control module 210, so that the master control end 110 can understand the working condition of the image building end 120 for overall system scheduling and management. Thus, the master control end 110 and the image building end 120 can effectively cooperate and maintain status synchronization, ensuring the stable and reliable operation and function realization of the entire medical imaging system 100.

[0094] Further, the image building end synchronization control module 130 can be powered by the master control end synchronization control module 210.

[0095] In some embodiments, the remote communication link can be a serial communication link, such as a differential serial communication RS485 link, etc. The master control end synchronization control module 210 can be an integrated circuit board for computer synchronization operation inserted into the bus slot of the master control end 110 (such as a PCI / PCIe slot), such as an STTH (Synchronized Turn on / Turn off card of Host, console synchronization switch-on and switch-off card), etc., or can be any one of the programmable logic devices, microcontrollers, etc. inserted or integrated in the master control end 110 for computer synchronization operation.

[0096] In some other embodiments, the remote communication link can be a network communication link, such as an Ethernet link, that is, using an Ethernet interface to enable communication between the master control end synchronization control module 210 and the image building end synchronization control module 130 through the network. Specifically, an Ethernet interface is added to the image building end synchronization control module 130 to enable it to receive the status information and control instructions of the master control end 110 through the network. In this way, the existing network hardware can be utilized without additional communication cables. The remote communication link can also adopt any one of local area network links, etc., which will not be elaborated here specifically.

[0097] In still some other embodiments, the remote communication link can be a wireless communication link, such as any one of a Bluetooth communication link, a Wi-Fi (Wireless Fidelity) communication link, etc. Specifically, a wireless communication module can be integrated into the image building end synchronization control module 130 to receive the status information and control instructions of the master control end 110 wirelessly, which can reduce cable connections and facilitate installation.

[0098] It should be noted that in some implementable ways, the master control end synchronization control module 210 can be connected to at least one image building end synchronization control module 130 through a remote communication link.

[0099] In some cases, refer to Figure 2b As shown, the image building end synchronization control module 130 can be integrated into the master control end synchronization control module 210. Among them, the image building end synchronization control module 130 integrated into the master control end synchronization control module 210 can be called the proximal image building end synchronization control module. Further, at least one image building end synchronization control module 130 can be integrated into the master control end synchronization control module 210.

[0100] In some embodiments, the remote communication link is a differential serial communication link.

[0101] Specifically, both the master control end synchronization control module 210 in the master control end 110 and the image building end synchronization control module 130 include differential serial communication interfaces. The master control end synchronization control module 210 and the image building end synchronization control module 130 are communicatively connected through the differential serial communication interfaces to communicate in a differential serial communication manner. At the same time, in the differential serial communication protocol, the power indication signal and reset signal status of the master control end 110 and the image building end 120 are added.

[0102] In some embodiments, refer to Figure 3a As shown, a proximal image building end synchronization control module 310 is also integrated in the master control end synchronization control module 210.

[0103] Among them, the proximal image building end synchronization control module 310 can be used to control the power on and off of the proximal image building end, and the proximal image building end is the image building end closer to the master control end.

[0104] Specifically, the master control end synchronization control module 210 is also integrated with the proximal image building end synchronization control module 310. Generally, the master control end is set in the control room, and the image building end is set in the equipment room (referred to as the remote image building end). The master control end is connected to the image building end synchronization control module corresponding to the image building end in the equipment room through a remote communication link. And the master control end synchronization control module is also integrated with the proximal image building end synchronization control module, which is beneficial to expanding the number of image building ends in the control room (the image building end set in the control room is called the proximal image building end), increasing the convenience of layout, and the ability to cope with the risk of downtime of the remote image building end.

[0105] In some embodiments, the image building end synchronization control module 130 is also used to communicate with the next-level object module.

[0106] Among them, the level where the imaging end synchronization control module 130 directly communicatively connected to the master control end 110 is denoted as the current level, and the next-level object module is the subsequent object module directly communicatively connected to the imaging end synchronization control module 130 at the current level.

[0107] Exemplarily, referring to Figure 3b As shown, the master control end 110 includes a master control end synchronization control module 210. The master control end synchronization control module 210 and the imaging end synchronization control module 130 are connected through a remote communication link. The imaging end synchronization control module 130 is also communicatively connected to the next-level object module, for sending the status information, related instructions, etc. of the master control end 110, and / or the status information of the imaging end 120, etc. to the next-level object module, and for receiving the information, instructions, etc. sent by the next-level object module.

[0108] Exemplarily, referring to Figure 3c As shown, the master control end 110 includes a master control end synchronization control module 210. The proximal imaging end synchronization control module 310 is integrated in the master control end synchronization control module 210 and is connected to the proximal imaging end 320. The proximal imaging end synchronization control module 310 is also communicatively connected to the next-level object module.

[0109] Exemplarily, referring to Figure 3d As shown, the master control end 110 includes a master control end synchronization control module 210. The master control end synchronization control module 210 is connected to an imaging end synchronization control module 130 through a remote communication link. A proximal imaging end synchronization control module 310 is also integrated in the master control end synchronization control module 210. Each imaging end synchronization control module can be communicatively connected to its corresponding next-level object module respectively.

[0110] It should be noted that the next-level object module can be any one of a sensor, an actuator, a data processing unit, a storage module, a communication module or a control module of other systems or devices, a mobile terminal, a synchronization control module of other imaging ends, etc., which can be specifically determined according to the actual application scenario or requirements, etc., and is not specifically limited in this specification.

[0111] The communication connection between the imaging end synchronization control module 130 and the next-level object module can adopt any one of remote communication connection, wireless communication connection, network communication connection, circuit communication connection, etc., and is not specifically limited in this specification.

[0112] In some embodiments, the next-level object module is the next-level imaging end synchronization control module; the imaging end synchronization control module 130 and the next-level imaging end synchronization control module are connected through a remote communication link.

[0113] Among them, the imaging end 120 connected to the imaging end synchronization control module 130 at the current level is denoted as the imaging end at the current level, and the imaging end connected to the imaging end synchronization control module at the next level is denoted as the imaging end at the next level.

[0114] Exemplarily, a master end synchronization control module 210 is included in the master end 110, denoted as STTH. STTH is connected to the imaging end synchronization control module 130 (denoted as STTR_1) through a remote communication link. STTR_1 is connected to the imaging end 1, and is also connected to the imaging end synchronization control module at the next level (denoted as STTR_2) through a remote communication link. STTR_2 is connected to the imaging end 2.

[0115] Exemplarily, a master end synchronization control module 210 is included in the master end 110, denoted as STTH. The proximal imaging end synchronization control module 310 (denoted as STTR_3) is integrated in STTH. STTR_3 is connected to the imaging end 3, and is also connected to the imaging end synchronization control module at the next level (denoted as STTR_4) through a remote communication link. STTR_4 is connected to the imaging end 4.

[0116] Exemplarily, a master end synchronization control module 210 is included in the master end 110, denoted as STTH. STTH is connected to an imaging end synchronization control module 130 through a remote communication link, denoted as STTR_1, which is connected to the imaging end 1. STTR_1 is also connected to the corresponding imaging end synchronization control module at the next level (denoted as STTR_2) through a remote communication link. STTR_2 is connected to the imaging end 2.

[0117] A proximal imaging end synchronization control module 310 is also integrated in STTH, denoted as STTR_3, which is connected to the imaging end 3. STTR_3 is also connected to the corresponding imaging end synchronization control module at the next level (denoted as STTR_4) through a remote communication link. STTR_4 is connected to the imaging end 4. In this embodiment, both STTR_1 and STTR_3 are imaging end synchronization control modules at the current level.

[0118] It should be noted that the imaging end synchronization control module at the next level can also be connected to the imaging end synchronization control module at the next lower level through a remote communication link. Thus, through the cascading function of the imaging end synchronization control module, reliable cascaded communication between the master end and multiple imaging ends can be achieved, meeting the requirements of long-distance and multi-device synchronous control. Moreover, the system architecture design is flexible, easy to expand and maintain, supports adding or reducing imaging ends, realizes the modularization of the system, and effectively improves the scalability of the synchronous control scheme.

[0119] In some realizable ways, the master control end (or the master control end synchronization control module within the master control end) is connected to the image building end synchronization control module through a remote communication link. The remote communication links between the remote communication link and the image building end synchronization control modules at different levels can adopt the same communication method or different communication methods, which are not specifically limited in this specification.

[0120] In some embodiments, the number of image building ends 120 is multiple; the multiple image building ends 120 are respectively connected to the same image building end synchronization control module 130 through their respective peripheral interfaces and switch signal lines.

[0121] Specifically, in a scenario where synchronization control is required between the master control end 110 and the multiple image building ends 120, the multiple image building ends 120 can be connected to the same image building end synchronization control module 130. Specifically, for each image building end 120, it is connected to the same image building end synchronization control module 130 through its respective peripheral interface and switch signal line, so that the same image building end synchronization control module 130 can respectively monitor the signals of the multiple image building ends 120 and control the states of the multiple image building ends 120, thereby meeting the requirements of unified management and synchronization control between the master control end 110 and the multiple image building ends 120, being convenient for installation, and reducing the communication and control delay between the master control end 110 and the multiple image building ends 120.

[0122] In some embodiments, refer to Figure 4a As shown, the master control end 110 includes a master control end synchronization control module 210. The master control end synchronization control module 210 is connected to the image building end synchronization control module 130 through a remote communication link. The multiple image building ends 120 are respectively connected to the image building end synchronization control module 130 through their respective peripheral interfaces and switch signal lines.

[0123] In some other embodiments, refer to Figure 4b As shown, the master control end 110 includes a master control end synchronization control module 210. The image building end synchronization control module 130 is integrated within the master control end synchronization control module 210. The multiple image building ends 120 are respectively connected to the image building end synchronization control module 130 within the master control end synchronization control module 210 through their respective peripheral interfaces and switch signal lines.

[0124] In some embodiments, the peripheral interface is a USB interface.

[0125] Exemplarily, refer to Figure 5 As shown, the overall framework of the medical imaging system provided in this specification may include a console computer, an image building computer, and an image building machine control card STTR.

[0126] In the PCIe slot of the console computer, a console control card STTH is inserted. STTH can obtain the power signal (+12V), reset signal (RST), ground signal (GND) of the console computer through the PCIe slot, and receive the power switch button signal PWR_SW of the console computer through the power switch PWR_SW module. STTH also includes a differential serial communication interface, which is used to connect to the differential serial communication interface of the camera control card STTR_1 that controls the power on and off of multiple cameras through a network cable (30m) for differential serial communication, so as to uniformly manage and control the synchronous power on and off operations of multiple imaging computers. The network cable can include a network cable for transmitting the power signal (+12V), a positive wire and a negative wire (TX+, TX-, RX+) for transmitting data between STTR and STTH, and a network cable for transmitting the ground signal (GND).

[0127] STTR_0 is also integrated in STTH, which is used to reserve a power signal and a reset signal detection circuit and a power on and off control circuit for one camera to cope with the situation that one camera is reserved at the console end or there is only one camera. In addition, a JTAG interface is also provided in STTH, which can be used for debugging.

[0128] In the case that one camera 0 is reserved at the console end or there is only one camera 0 in the medical imaging system, STTR_0 is connected to camera 0 through a USB cable and a power on and off cable. The USB interface of STTR_0 can be connected to the USB interface of camera 0 through a USB cable (USB Cable), so that STTR_0 can obtain the power signal (+5V) and reset signal RST (through specific signal lines of USB, such as D+ / D-) of camera 0 through the USB interface, realizing the status monitoring and control of imaging computer 0. STTR_0 is also used to generate a power enable signal PWR_RE, which is used to control the contact of the relay module in STTR_0 to close, so as to generate a power switch signal (Power_on_ctrl) and send it to camera 0 through the switch signal line to control the status adjustment of camera 0. The control of the relay contact is rapid, and the simulated key operation is accurate, which can realize the stable power on and off and restart control of the imaging computer.

[0129] STTR_1 receives various signals transmitted by STTH through the network cable. STTR_1 is respectively connected to 4 cameras (camera 1, camera 2, camera 3, camera 4). For the specific description of the connection between STTR_1 and 4 cameras respectively, please refer to the above description of the connection between STTR_0 and camera 0, and the details will not be repeated here.

[0130] Each imaging computer does not need to insert a power-on / off control card internally. The PCIe slot can be reserved for the imaging card, but the power switch signal needs to be led out through a connector. That is, it is necessary to receive the power switch signal (Power_on_ctrl) generated by the connected STTR through an external switch signal line to perform corresponding power-on and power-off operations.

[0131] Further, continue to refer to Figure 5 As shown, STTR_1 can also be connected to other imaging camera control cards through a network cable for differential serial communication, enabling the STTR card to support the cascading function. Multiple STTR cards can be connected through a cable, facilitating the expansion of the synchronous control requirements of multiple imaging computers. In this way, STTH performs cascading communication with multiple STTR cards through a differential serial communication interface, supporting long-distance stable communication, thereby realizing the unified management and reliable control of multiple imaging computers over a long distance, with strong scalability. In addition, through communication protocol optimization, adding the power indication signal and reset signal status information of the master console computer and each imaging computer to the communication protocol can ensure the accuracy of synchronous control.

[0132] In the overall framework of the above medical imaging system, the STTR card adopts an external design (i.e., externally placed in the imaging computer), which can avoid occupying the PCIe slot of the imaging computer, reserve the PCIe slot resources for the imaging card, and solve the problem that the control card cannot be inserted due to insufficient PCIe slots occupied by the imaging card. At the same time, the STTR card does not need to be powered separately and can be powered through the USB interfaces of the master console control card STTH and the imaging computer. Through this power supply method optimization, the power supply design can be simplified and the system reliability can be improved. At the same time, the system has strong compatibility and can adapt to imaging computers of different models and brands, with consistent control effects.

[0133] In addition, the STTR card uses an FPGA to control the closing / opening of the relay contacts. The contacts of the relay are connected to the power switch interface of the imaging computer (regarding the contacts of the relay as an extension of the power switch. When the relay contacts are closed, it is equivalent to forming a path at the power switch interface of the imaging computer, so that the power switch circuit of the imaging computer receives a trigger signal) to simulate manual button operations, realizing reliable power-on / off and restart of the imaging computer, with precise and reliable control, and a flexible system architecture, which is easy to expand and maintain. Among them, the relay can also be replaced by any one of a transistor, a field effect transistor, an optocoupler device, etc.

[0134] Based on the overall framework of the above medical imaging system, the implementation process of synchronous control between the master console computer and the imaging computer can include:

[0135] (1) Initialization stage

[0136] A differential serial communication connection is established between STTH and STTR.

[0137] When the host computer is powered on and the recon computer is not powered on, STTH is powered through the PCIe slot, and STTR is powered through STTH; when both the host computer and the recon computer are powered on, STTH is powered through the PCIe slot, and STTR is powered through the USB interface.

[0138] (2) Synchronous startup

[0139] After the host computer starts up, STTH detects that the power signal of the host computer is in the on state.

[0140] STTH uniformly controls the relay contacts on each STTR to close for powering on all recon computers.

[0141] STTH sends query commands to each STTR through differential serial communication to obtain the power status of each recon computer.

[0142] If a certain STTR detects that the recon computer it is connected to is not turned on, then this STTR controls the relay contact to close through the FPGA, simulating pressing the power button of the recon computer to start the corresponding recon computer.

[0143] (3) Synchronous shutdown

[0144] When the host computer shuts down normally, STTH loses power, and STTR cannot receive the status signal and power signal of STTH.

[0145] When STTR determines that STTH has shut down, it controls each relay contact to close for a short time through the FPGA, simulating pressing the power button of the recon computer for a short time to normally shut down the corresponding recon computers.

[0146] If a certain recon computer cannot be shut down normally, the FPGA controls the corresponding relay contact to close for a long time, simulating pressing the power button of the recon computer for a long time to forcefully shut down this recon computer.

[0147] (4) Reboot operation

[0148] When the host computer reboots normally, STTH does not lose power, and STTR will receive the reset signal and power signal of STTH.

[0149] When STTR determines that STTH has been reset, it controls each relay contact to close for a short time through the FPGA, simulating pressing the power button of the recon computer for a short time to normally shut down the corresponding recon computers.

[0150] After each image reconstruction computer is shut down, the STTR controls each relay contact to close for a short time through the FPGA, simulating pressing the power button of the image reconstruction computer for a short time to normally turn on each image reconstruction computer, thereby realizing the restart of each image reconstruction computer.

[0151] (5) Status detection

[0152] The STTR reads the power supply and reset signal status of the corresponding image reconstruction computer through the USB interface and feeds it back to the STTH.

[0153] The console computer can monitor the operating status of each image reconstruction computer in real time and perform necessary control and management.

[0154] The embodiment of this specification also provides a synchronization control method, which is applied to the image reconstruction end synchronization control module in the medical imaging system in any of the foregoing embodiments. The synchronization control method may include the following steps.

[0155] S610. Obtain the status of the master control end and obtain the status of the image reconstruction end through the peripheral interface.

[0156] S620. If the status of the image reconstruction end is not synchronized with the status of the master control end, send the power switch signal to the image reconstruction end through the switch signal line to adjust the status of the image reconstruction end to be synchronized with the status of the master control end.

[0157] It should be noted that for the description of the synchronization control method in the above embodiments, please refer to the description of the medical imaging system in this specification, and details are not repeated here.

[0158] The embodiment of this specification also provides a synchronization control device, which is applied to the image reconstruction end synchronization control module in the medical imaging system in any of the foregoing embodiments. The synchronization control device may include: a master control end status determination module, an image reconstruction end status determination module, and an image reconstruction end status adjustment module.

[0159] The status acquisition module is used to obtain the status of the master control end and obtain the status of the image reconstruction end through the peripheral interface.

[0160] The status adjustment module is used to, if the status of the image reconstruction end is not synchronized with the status of the master control end, send the power switch signal to the image reconstruction end through the switch signal line to adjust the status of the image reconstruction end to be synchronized with the status of the master control end.

[0161] For the specific limitations of the synchronization control device, reference can be made to the limitations of the synchronization control method in the foregoing text, which will not be elaborated here. Each module in the foregoing synchronization control device can be implemented in whole or in part by software, hardware, and their combination. Each of the foregoing modules can be embedded in the processor of the computer device in hardware form or independent of it, or stored in the memory of the computer device in software form, so as to facilitate the processor to call and execute the operations corresponding to each of the foregoing modules.

[0162] An embodiment of this specification also provides a computer device, which may include a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the foregoing synchronization control method is implemented.

[0163] An embodiment of this specification also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the foregoing synchronization control method is implemented.
