Description

Technical Field

[0001] This application belongs to the field of medical technology, and in particular relates to a control method, processing method and device for an X-ray system. Background Technology

[0002] Computed tomography (CT) equipment mainly consists of several parts, including an X-ray system (high-voltage X-ray tube), a control system, a data acquisition system, and a data processing system. The high-voltage X-ray tube is the core component of the CT system. The high-voltage generator outputs high voltage, filament drive signals, and anode drive signals, which are applied to the X-ray tube to drive the anode to rotate, heating the filament to generate thermionic electrons. This high voltage is then applied between the anode and cathode of the X-ray tube, accelerating the electrons and directing them to the anode target to generate X-rays. The X-ray tube in a CT system involves high temperature, high insulation, high vacuum, and high voltage conditions. Existing CT systems have inadequate control procedures, insufficient protection for the X-ray tube, and low scanning efficiency. Summary of the Invention

[0060] This application provides a control method for an X-ray system, which can perform X-ray system-related controls according to different stages of patient scanning. The following description uses a CT system as an example of electronic equipment. Figure 1 This is a schematic diagram illustrating the implementation flow of a control method for an X-ray system provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0061] Step S101: After the patient completes registration, a preparation command is sent to the X-ray system, wherein the X-ray system performs preliminary preparation based on the preparation command and then issues first status feedback information to indicate that the preliminary preparation is complete.

[0062] In this embodiment, the X-ray system includes a high-voltage generator and an X-ray tube. Patient registration is a process of recording and identifying patient information, typically including basic patient information (such as name, age, gender, contact information, etc.), medical history, allergy history, etc. By completing registration in a Hospital Information System (HIS) or Radiology Information System (RIS), the CT system can accurately associate the patient with the upcoming X-ray examination. The preparation command is used to notify the X-ray system to begin preliminary preparations for the examination. The first status feedback information is the information fed back to the CT system by the X-ray system after completing preliminary preparations, indicating that the X-ray system has completed basic preparations such as equipment self-check and warm-up. In some embodiments, the first feedback information may also include detailed information such as equipment status, preparation status, possible warnings or error codes, etc.

[0063] In this embodiment, the CT system and the X-ray system can communicate via network communication or hardware interface. The communication connection method can include Ethernet, Wi-Fi, etc.

[0064] In this embodiment of the application, during communication, the format of the communication interaction information needs to be set according to the communication protocol. For example, the preparation command and the first status feedback information can be referred to as interaction information, which may include: a command field, a parameter field, and a data verification field. For the preparation command, the command field includes information used to characterize the preparation command.

[0065] In this embodiment, when the X-ray system receives a preparation command, it can perform operations such as initial anode activation and filament standby current loading. In some embodiments, the X-ray system also performs optional grid control and optional magnetocontrol preparations. After the X-ray system completes preparation, it sends first status feedback information indicating the completion of initial preparation to the CT system.

[0066] In some embodiments, different scanning powers may be used for different parts to be scanned, and the pre-preparation requirements for the X-ray system may also be different depending on the part, thereby enabling more intelligent control of the X-ray system.

[0067] In this embodiment, the area to be scanned can be determined based on the patient's registration information; preliminary preparation requirements can be determined based on the area to be scanned; and the preparation command can be generated based on the preliminary preparation requirements.

[0068] In this embodiment, the preliminary requirements may include: the anode rotation speed requirement and / or the filament current requirement. For example, for areas requiring high-power scanning, the anode can be pre-set at a higher rotation speed, while for low-power scanning areas, it can be pre-set at a lower rotation speed. A similar strategy can be used for the filament current.

[0069] Step S102: Upon receiving the first status feedback information from the X-ray system, a scanning parameter command is sent to the X-ray system. The X-ray system prepares based on the scanning parameters in the scanning parameter command, and after preparation is completed, it sends a second status feedback information to indicate that preparation is complete.

[0070] In this embodiment of the application, when the CT system receives the first status feedback information sent by the X-ray system, it determines that the preliminary preparation is complete. At this time, a scanning parameter command can be sent to the X-ray system.

[0071] In this embodiment, the scanning parameter command is a command generated based on scanning parameters. The scanning parameter command carries scanning parameters, which may include instructions containing specific X-ray scanning parameters, such as tube voltage (kV), tube current (mA), scanning time, scanning angle, scanning length, gantry speed, pitch, exposure time, focal spot size, and focal spot position. These parameters are determined based on factors such as the patient's body part and the purpose of the examination. The CT system packages these parameters into a single command and sends it to the X-ray system to guide the X-ray system in more precise scan preparation.

[0072] In this embodiment, the scanning parameters can be set by the doctor. In some embodiments, the scanning parameters can also be determined based on the patient's information and the area to be scanned, and a scanning parameter command can be generated based on the scanning parameters.

[0073] In this embodiment, after receiving the scanning parameter command, the X-ray system performs further preparations. Based on the initial anode state, the anode rotation speed or filament current can be further increased to prepare for subsequent processes. In this embodiment, the X-ray system can further control the X-ray tube to ensure that the anode, filament, and focus control are ready.

[0074] In this embodiment of the application, the preparation based on the scanning parameters in the scanning parameter command includes: determining the target rotational speed of the anode and the target current of the filament based on the scanning parameter command; controlling the rotational speed of the anode to increase to the target rotational speed, and controlling the current of the filament to increase to the target current.

[0075] In this embodiment, the X-ray system calculates the target rotational speed of the anode and the target current of the filament based on scanning parameters. According to the scanning parameters and the specifications of the X-ray tube, the maximum heat load that the anode can withstand within a given time can be calculated. Based on the maximum heat load and the thermal conductivity of the anode material, the anode rotational speed required to achieve thermal equilibrium can be calculated. In this embodiment, the filament current determines the filament temperature and the number of emitted electrons, thus affecting the generation of X-rays. The required X-ray dose can be calculated based on the scanning parameters and image quality requirements. Based on the required X-ray dose and the characteristics of the filament material, the filament temperature required to achieve the required X-ray dose can be calculated. Based on the filament temperature-current relationship (usually obtained through experiments or data provided by the manufacturer), the filament current required to achieve the required filament temperature can be determined.

[0076] In this embodiment, after completing all scanning preparations according to the scanning parameter commands, the X-ray system sends a second status feedback signal to indicate that preparation is complete. When the X-ray system sends the second feedback signal, it means that the X-ray system has set the scanning parameters as required, and all components such as the X-ray tube and high-voltage generator are ready for exposure operation, awaiting the trigger information to execute the exposure. The second status feedback signal is also information transmitted to the CT system via a specific communication method.

[0077] Step S103: Upon obtaining the second state feedback information and the trigger information for performing exposure, an operation command to perform exposure is issued to the X-ray system, wherein the X-ray system performs the exposure operation based on the operation command.

[0078] In this embodiment, the exposure trigger information is a signal used to start the X-ray system to perform the exposure operation. The exposure trigger information can be a signal generated by the operator clicking the "Exposure" button on the control interface, or it can be a signal generated according to a preset automated process (such as timed exposure or exposure linked with other equipment).

[0079] In this embodiment, the CT system sends an operation command to the X-ray system, instructing the X-ray system to begin exposure. Upon receiving this command, the X-ray system activates the high-voltage generator, causing the X-ray tube in the X-ray system to emit X-rays, and the detector begins acquiring data.

[0080] In this embodiment, the issuance of operation commands is not limited to software or hardware interfaces; they can be controlled through both software and hardware to ensure the effective and reliable execution of critical control instructions. During exposure, the CT system and X-ray system also maintain information exchange, transmitting relevant scanning parameters and status information.

[0081] In this embodiment, upon completion of patient registration, a preparation command is sent to the X-ray system. The X-ray system performs preliminary preparation based on the preparation command and then issues a first status feedback message indicating the completion of preliminary preparation. Upon receiving the first status feedback message from the X-ray system, a scanning parameter command is sent to the X-ray system. The X-ray system performs preparation based on the scanning parameters in the scanning parameter command and, upon completion of preparation, issues a second status feedback message indicating the completion of preparation. Upon receiving the second status feedback message and obtaining trigger information for exposure execution, an operation command for exposure execution is sent to the X-ray system. The X-ray system executes the exposure operation based on the operation command. This allows for control of the X-ray system through information interaction, enabling preparation of the X-ray system and protecting the X-ray tube. Furthermore, this control process can be automatically executed based on the interacting information, improving scanning efficiency.

[0082] Figure 2 This is a schematic diagram illustrating the implementation flow of another X-ray system control method provided in an embodiment of this application, as shown below. Figure 2 As shown, during the patient preparation phase, a preparation command is issued, and the X-ray system performs initial preparation, including initial anode preparation and filament preparation. After preparation is complete, a status feedback message is sent to the CT system. Following initial preparation, the patient is positioned. After positioning, the CT system sets and determines the scanning parameters and sends these parameters to the X-ray system via a scan parameter command. At this time, the X-ray system performs anode and filament preparation. After preparation is complete, a status feedback message can be sent to the CT system. The CT system can then determine whether to execute the exposure command and sends the exposure command to the X-ray system. The X-ray system outputs X-rays for exposure. After the scan is completed, a scan completion message is sent to the CT system. In some embodiments, multiple areas may need to be exposed, in which case bed relocation and other preparations may be performed. Upon receiving a confirmation to execute the exposure command, the exposure operation continues.

[0083] In some embodiments, prior to step S101, the method further includes:

[0084] Upon receiving a trigger operation to power on the X-ray system, a power-on command is sent to the X-ray system, wherein the X-ray system sends power-on status feedback information after power-on.

[0085] In this embodiment, the triggering operation can take the form of clicking a specific "power on" button on the CT system (such as a console computer, dedicated operation panel, etc.). This button click action will be recognized by the corresponding hardware or software system and used as a trigger signal. Alternatively, in an automated control scenario, according to preset program logic and time schedule, when certain conditions are met (such as the completion of equipment self-test, the end of relevant pre-processing, etc.), the system automatically generates and sends out a similar trigger signal, just like automatically turning on the power supply of a device after a countdown ends.

[0086] In this embodiment, an instruction can be generated and sent to the X-ray system based on the received power-on trigger operation. The main function of the power-on instruction is to notify the X-ray system that it can start powering on and initiate the initialization and power-on process of its internal components. Upon receiving the power-on trigger signal, the CT system will convert the "power-on" intent into a power-on instruction that meets the format requirements, according to the communication requirements of the X-ray system and the established instruction generation rules. The generated power-on instruction will be sent out through the corresponding communication interface. When the X-ray system receives the power-on instruction, the software system starts running and, according to the control timing, begins powering on the high-voltage X-ray tube system at a certain time, including low-voltage, auxiliary, and three-phase power. Different CT systems can adjust the three power supplies, including the timing, as needed.

[0087] In this embodiment, the CT system receives power-on status feedback information, which is then interpreted by the CT system's software. For example, based on the status code in the feedback information, the system determines whether the X-ray system has only completed initial power-on or has completed the initialization of all components, etc., in order to decide on the next step of the operation, such as whether subsequent preparation commands can be sent immediately.

[0088] Figure 3 A schematic diagram illustrating the implementation flow of a control method for an X-ray system provided in this application embodiment is shown below. Figure 3 As shown, the user can press the CT machine power-on button to power on the CT system. The CT system then sends a power-on command to the X-ray system, which in turn powers on the X-ray system and establishes a communication connection between the CT system and the X-ray system. The X-ray system then sends power-on status feedback information to the CT system, thus completing the power-on control.

[0089] In this embodiment, after the X-ray system is powered on, the CT system establishes communication with the X-ray system to obtain basic information about the X-ray system, including but not limited to status information, model, serial number, and version information. In this design, the high-voltage system and the X-ray tube are treated as a whole and interact with the system. Within the X-ray subsystem, the high-voltage system and the X-ray tube can also interact as needed, transmitting X-ray tube-related information and parameters to the high-voltage system for unified control.

[0090] In some embodiments, the method further includes:

[0091] When the X-ray system is started and / or when it has not been used for a preset period of time, a standby command is sent to the X-ray system to put the X-ray system into standby mode.

[0092] In this embodiment of the application, after the X-ray system is started, it is controlled to enter a standby state.

[0093] In this embodiment, the preset duration is a pre-defined, user-configurable time period. If the X-ray system does not receive any operation instructions or detect any activity (such as no radiation emission, no data input or output, etc.) within this period, the system will consider it to be in an unused state. The usage duration can be monitored by adding sensors or counters to the X-ray system.

[0094] In some embodiments, a user interface (such as a touchscreen, keyboard, or remote management software) may be provided to allow users to set a preset duration. Users can also configure whether to enable this standby function and specific behaviors in standby mode (such as whether to retain certain functions).

[0095] When the system detects a state of inactivity, it automatically generates and sends a standby command to the X-ray system. This command is typically an electrical signal or network data packet, used to instruct the X-ray system to enter a low-power standby mode. The standby command can be sent to the X-ray system's control unit via the internal bus or network interface.

[0096] In standby mode, some or all functions of the X-ray system are suspended or power consumption is reduced to save energy and extend equipment life. Typically, the system in standby mode can still respond to certain wake-up signals to quickly resume operation when needed. For example, in standby mode, the anode speed is reduced or turned off, the filament is turned off or switched to a lower current value, the radiator fan speed is reduced or turned off, etc. By entering standby mode, the X-ray tube is protected, reducing damage and extending its lifespan; it also reduces system power consumption from an energy-saving perspective.

[0097] In this embodiment, by placing the X-ray system in standby mode, its energy consumption can be significantly reduced, thereby saving electricity costs and reducing environmental impact. Prolonged standby also extends the lifespan of the X-ray system by reducing unnecessary wear and heat buildup.

[0098] In some embodiments, after the X-ray system has entered standby mode, the X-ray system also sends status feedback information to the CT system.

[0099] In some embodiments, the method further includes:

[0100] Upon receiving a trigger operation to power down the X-ray system, a power-down command is sent to the X-ray system, wherein the X-ray system, based on the power-down command, shuts down the anode of the X-ray system and shuts down the filament of the X-ray system.

[0101] In this embodiment, the power-down trigger operation can be an operation performed by a user through a user interface (such as a touchscreen, keyboard, button, or remote management software), or it can be a condition automatically detected by the system (such as the arrival of a preset shutdown time, power failure, etc.). Once the trigger operation is confirmed, the system generates a power-down command. This command is usually an electrical signal or network data packet containing detailed information required to perform the shutdown operation. The power-down command is sent to the control unit of the X-ray system via an internal bus, network interface, or other communication channels. The anode is a key component in the X-ray tube; it receives the electron beam from the cathode and accelerates these electrons to generate X-rays. Under the action of the power-down command, the power supply to the anode is cut off, thereby stopping the generation of X-rays. The filament is another important component in the X-ray tube; it is heated and releases electrons. Under the action of the power-down command, the power supply to the filament is also cut off, thereby stopping the release of electrons. After the state of the X-ray system meets the power-down conditions, the high-voltage generator feeds back the corresponding state, the X-ray system performs a high-voltage power-off operation, and after completing other related operations, the entire machine is powered down. When the X-ray system is completely shut down, it may send a notification to the user informing them that the X-ray system has been successfully powered off.

[0102] In some embodiments, after receiving a power-down command, it can be determined whether the state of the X-ray system meets the preconditions for power-down. If the preconditions are met, the anode and filament of the X-ray system are turned off. The thermal state information of the X-ray tube in the X-ray system can be detected to determine whether the preconditions for power-down are met. The thermal state information may include the temperature of the X-ray tube; if the temperature is below a preset temperature, the preconditions for power-down are met.

[0103] In this embodiment, the X-ray system may gradually reduce the power supply voltage to avoid damage to the equipment caused by a sudden power outage.

[0104] The method provided in this application embodiment, through reasonable triggering operations, generation and transmission of power-down commands, and the response mechanism of the X-ray system, can ensure that the X-ray system can be smoothly shut down when needed.

[0105] Figure 4 This is a schematic diagram illustrating the implementation flow of a control method for an X-ray system provided in an embodiment of this application, as shown below. Figure 4 As shown, upon receiving a power-down command, the X-ray system sends the command to the X-ray system. The X-ray system then shuts off the anode, filament, and begins cooling the lamp tube. During this process, feedback is sent to the CT system. If the CT system determines that power-down is possible based on the status, it sends a high-voltage power-off operation to the X-ray system. The CT system then performs the power-down, completing the process.

[0106] In some embodiments, the method further includes: upon receiving abnormal information reported by the X-ray system, determining the restricted functions of the X-ray system and the functions that the X-ray system can perform based on the abnormal information; and outputting the restricted functions and the functions that can be performed.

[0107] In this embodiment, the X-ray system can perform anomaly detection, monitoring the system's operational status in real time. When an anomaly is detected, these sensors trigger the generation of anomaly information. This anomaly information is reported to the CT system via an internal bus, network interface, or other communication channels. The CT system receives and parses the reported anomaly information to determine the specific type, location, and severity of the anomaly. Based on the analysis results, the system assesses the current functional status of the X-ray system. This includes determining which functions are restricted (i.e., unable to function properly due to anomalies) and which functions can still be executed normally. Based on the assessment results, the CT system lists all functions restricted due to anomalies. These functions may include X-ray emission, image acquisition, data processing, etc. Simultaneously, the system also lists all functions that can still be executed normally under the current anomaly state. These functions may include basic system monitoring, fault alarms, data backup, etc. The system outputs information about restricted and executable functions to the user. This can be achieved through a user interface (such as a touchscreen, monitor, printer, etc.) or remote management software. The output information should be clear and concise so that the user can quickly understand the current status of the X-ray system.

[0108] In this embodiment of the application, through the abnormal information processing, functional evaluation and output mechanism, timely fault information and operation guidance can be provided to users, thereby helping users to quickly restore the normal operation of the X-ray system.

[0109] In some embodiments, if a CT system or high-pressure X-ray tube-related error occurs during a scan, the X-ray system determines the error type and reports it to the CT system. This supports a design that allows the CT system to quickly recover and complete the scan according to CT system instructions. Besides avoiding increased doses to the patient due to repeated scans, this is particularly valuable for contrast-enhanced scans and CTA scans, and it also prevents contrast agent loss that necessitates rescanning and re-injection of the contrast agent.

[0110] In some embodiments, the interaction information includes: command field, parameter field, and data verification field. The interaction information may include: preparation command, various status feedback information, scan parameter command, operation command to perform exposure, power-on command, standby command, power-off command, and abnormal information.

[0111] In some embodiments, the parameter fields in the scanning parameter command include: the number of exposure groups and the corresponding number of scanning parameter groups. When there are multiple exposures, the X-ray system, upon receiving the operation command, enters the preparation state for the next exposure after completing one exposure.

[0112] Different scenarios have different requirements for the control of X-ray systems. Therefore, the design of interactive information should maintain the flexibility of the interface and be able to support the expansion of different clinical application scenarios as needed.

[0113] From the perspective of the number of exposures in a single scanning process, exposure types in clinical scenarios can be categorized into single-shot exposure, multi-shot rapid repeated exposure, and single-shot rapid parameter switching scan, etc.

[0114] Single-shot exposure: Each exposure is a continuous exposure, with exposure times ranging from seconds to hundreds of seconds; for example, positioning images, spiral scanning protocols.

[0115] Multiple-shot repeated exposure: multiple exposures at certain time intervals (sub-second to ten-second intervals); for example, ordinary tomography scans, perfusion protocol scans, etc.

[0116] Single-shot fast parameter switching scan: Quickly switch a specific scan parameter, such as kV parameter or mA parameter, during a single scan.

[0117] From the perspective of exposure type, exposure in clinical scenarios can be similarly divided into timed exposure scans and untimed exposure scans. Timed exposure scans refer to scans where the start time of exposure is fixed, and exposure is performed from a certain time until it is completed. Untimed exposure scans refer to scans where the start time of exposure is affected by external triggering conditions, and the start time of exposure is determined according to the actual situation. For example, reviewing ECG-gated scans and respiratory-gated scans requires combining gating signals to control the exposure time.

[0118] For the interface design between the CT system and the X-ray system, we categorize and summarize different application scenarios, design a unified interface type and control flow for similar types, improve control efficiency, reduce control complexity, and decouple the system control from the underlying control of the X-ray subsystem.

[0119] In the embodiments of this application, Figure 5 This is a schematic diagram of an interactive information format provided in an embodiment of this application, such as... Figure 5As shown, the interactive information includes three basic parts: command fields, parameter fields, and data validation fields. Each part can be further subdivided. For the command field, the design is based on different control commands, such as power-on commands, commands to set scan parameters before scanning, commands to enter standby mode after a certain period following the completion of a scan, and system power-off commands. For different exposure types, the command field can be designed in more detail. For example, it can be used to distinguish between rapid parameter switching scans and other scanning processes, which differ significantly. For the parameter field, considering the different exposure types mentioned above, the parameter field needs to include the number of exposure groups (Group number) and the corresponding number of scan parameter groups (Group). Figure 6 This is a schematic diagram illustrating the format of a parameter field provided in an embodiment of this application, such as... Figure 6 As shown, each group includes parameters such as expected exposure duration, kV parameters, mA parameters, focal size parameters, focal position parameters, interval between two shots, and number of repetitions. The number of repetitions here refers only to the number of repetitions for the kV / mA exposure time scan within the current group. For perfusion scans and similar clinical scenarios, there may be scenarios involving multiple consecutive multi-shot scans. Therefore, the X-ray system interface design can provide corresponding interfaces to support the application requirements of different scan parameters under different groups. For clinical scenarios requiring rapid, continuous multi-shot scans, this can save time spent on interaction between the CT and X-ray systems. Furthermore, the X-ray system can quickly enter the preparation state for the next scan after completing the previous scan based on pre-acquired parameters, achieving better control over kV, mA, and X-ray tube focal length, resulting in a better clinical experience. For single-shot rapid parameter switching scans, the definition of parameter fields is not entirely consistent with other scans; it is also necessary to transmit the duration (hundreds of microseconds) for rapidly switching between different parameters, the number of switching times, etc.

[0120] In this embodiment, for single-shot fast parameter switching scans, the definition of the parameter fields is not entirely consistent with other scans. It is also necessary to transmit the duration (hundreds of microseconds) of fast switching between different parameters, the number of switching operations, etc. For example, the command word for kVp switching can inform the high-voltage system of the planned scan parameter sequence in advance through the command word, and combined with the I / O control interface, achieve precise control of high-voltage kV switching.

[0121] The same architecture can be used to support fast DOM process design. The system sends the tube current parameters corresponding to each data acquisition to the X-ray system in advance. The X-ray system then precisely controls the output of the sink current according to the control instructions, thereby achieving faster dose modulation.

[0122] Based on the foregoing embodiments, this application provides a processing method for an X-ray system, applicable to X-ray systems. Figure 7A flowchart illustrating a processing method for an X-ray system provided in this application embodiment is shown below. Figure 7 As shown, it includes:

[0123] Step S701: After obtaining the preparation command and performing preliminary preparation based on the preparation command, a first status feedback message is issued to indicate that the preliminary preparation is completed. The preparation command is sent by the CT system when it obtains that the patient has completed registration.

[0124] In this embodiment, when the X-ray system receives a preparation command, it can perform operations such as initial anode activation and filament standby current loading. In some embodiments, the X-ray system also performs optional grid control and optional magnetocontrol preparations. After the X-ray system completes preparation, it sends first status feedback information indicating the completion of initial preparation to the CT system.

[0125] Step S702: Upon receiving the scanning parameter command, preparation is performed based on the scanning parameters in the scanning parameter command. After preparation is completed, a second state feedback message indicating the completion of preparation is issued. The scanning parameter command is sent by the CT system upon receiving the first state feedback message.

[0126] In this embodiment, the scanning parameter command is a command generated based on scanning parameters. The scanning parameter command carries scanning parameters, which may include instructions containing specific X-ray scanning parameters, such as tube voltage (kV), tube current (mA), scanning time, scanning angle, scanning length, gantry speed, pitch, exposure time, focal spot size, and focal spot position. These parameters are determined based on factors such as the patient's body part and the purpose of the examination. The CT system packages these parameters into a single command and sends it to the X-ray system to guide the X-ray system in more precise scan preparation.

[0127] In this embodiment, after receiving the scanning parameter command, the X-ray system performs further preparations. Based on the initial anode state, the anode rotation speed or filament current can be further increased to prepare for subsequent processes. In this embodiment, the X-ray system can further control the X-ray tube to ensure that the anode, filament, and focus control are ready.

[0128] Step S703: If an operation command to perform exposure is obtained, the exposure operation is performed, wherein the operation command is sent by the CT system upon obtaining the second state feedback information.

[0129] In this embodiment of the application, after receiving this command, the X-ray system will turn on the high-voltage generator, causing the X-ray tube in the X-ray system to emit X-rays, and the detector will begin to collect data.

[0130] The method provided in this application embodiment, after obtaining a preparation command and performing preliminary preparation based on the preparation command, issues a first state feedback message indicating the completion of preliminary preparation, wherein the preparation command is sent by the CT system upon obtaining information that the patient has completed registration; upon obtaining a scanning parameter command, preparation is performed based on the scanning parameters in the scanning parameter command, and upon completion of preparation, a second state feedback message indicating the completion of preparation is issued, wherein the scanning parameter command is sent by the CT system upon obtaining the first state feedback message; upon obtaining an operation command to perform exposure, an exposure operation is performed, wherein the operation command is sent by the CT system upon obtaining the second state feedback message. This method enables control of the X-ray system through information interaction to prepare the X-ray system, thereby protecting the X-ray tube. In addition, this control process can be automatically executed based on feedback information, which can improve scanning efficiency.

[0131] In some embodiments, the preparation based on the scan parameters in the scan parameter command includes:

[0132] The target rotational speed of the anode and the target current of the filament are determined based on the scanning parameter command;

[0133] The rotational speed of the anode is controlled to increase to the target rotational speed, and the current of the filament is controlled to increase to the target current.

[0134] In this embodiment, the X-ray system calculates the target rotational speed of the anode and the target current of the filament based on scanning parameters. According to the scanning parameters and the specifications of the X-ray tube, the maximum heat load that the anode can withstand within a given time can be calculated. Based on the maximum heat load and the thermal conductivity of the anode material, the anode rotational speed required to achieve thermal equilibrium can be calculated. In this embodiment, the filament current determines the filament temperature and the number of emitted electrons, thus affecting the generation of X-rays. The required X-ray dose can be calculated based on the scanning parameters and image quality requirements. Based on the required X-ray dose and the characteristics of the filament material, the filament temperature required to achieve the required X-ray dose can be calculated. Based on the filament temperature-current relationship (usually obtained through experiments or data provided by the manufacturer), the filament current required to achieve the required filament temperature can be determined.

[0135] In this embodiment, hardware components such as a motor driver are used to gradually adjust the rotational speed of the anode until the previously calculated target rotational speed is reached. Hardware components such as a power supply are used to gradually adjust the filament current until the previously calculated target current is reached.

[0136] The method provided in this application determines the target rotation speed of the anode and the target current of the filament based on the scanning parameter command; controls the rotation speed of the anode to increase to the target rotation speed, and controls the current of the filament to increase to the target current, ensuring that the X-ray tube operates with optimal parameters during the scanning process, thereby meeting the various requirements in the scanning parameter command and generating high-quality X-ray images.
