[0026] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0027] It should be noted that in the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0028] In order to clearly describe the technical solutions of the embodiments of the present disclosure, in the embodiments of the present disclosure, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0029] During radiotherapy, radiotherapy equipment can collect patient imaging information through an image control system (also known as an image guidance system), promptly detect changes in the location and morphology of the tumor, and make timely adjustments to the patient's position or treatment plan, thereby improving the accuracy and safety of radiotherapy.

[0030] The image control system is usually deployed in a radiotherapy system. Specifically, the image control system is usually deployed in a radiotherapy control system. Figure 1 A schematic diagram of the structure of a general radiotherapy control system is shown in FIG. Figure 1 As shown, the radiotherapy control system may generally include: a main controller and an image control system.

[0031] The main controller receives treatment data, decomposes and forwards it to the various control nodes, and monitors and coordinates the operation of each control node. The imaging control system is used to image the treatment area before and / or during treatment to monitor the treatment area.

[0032] The image control system (also known as the IGS system (Image Guided System)) includes: IGS electrical box, image server and image acquisition equipment. The IGS electrical box is equipped with related image control components including the IGS controller, exposure control unit (Image Control Unit, ICU) and so on.

[0033] When the radiotherapy control system acquires images through the imaging control system, the main controller typically sends image acquisition instructions via the IGS controller to the ICU in the IGS electrical box. In response to the received image acquisition instructions, the ICU controls the image acquisition equipment to capture the target image of the patient. Subsequently, the image acquisition equipment transmits the captured target image to the image server for processing (e.g., reconstruction).

[0034] according to Figure 1 As shown, in a common IGS system, the image server is usually installed outside the IGS electrical box, and the exposure control unit is installed inside the IGS electrical box. Data is usually exchanged between the two through serial communication (such as Recommended Standard 232 (RS232)) or input and output interfaces. The transmission rate is limited, and when the rack rotates, the connection reliability between the two is poor.

[0035] To address the aforementioned technical issues, the present disclosure provides an integrated image control system that integrates an image server and an exposure control unit on a single control backplane, connecting them via a motherboard bus. This motherboard bus connection improves the data transmission rate between the image server and the exposure control unit. Furthermore, integrating the image server and the exposure control unit on the same control backplane also enhances the stability of the connection between them during rack rotation. This avoids the common issues of low data transmission rates and unstable connections caused by cables between the image server and the exposure control unit.

[0036] Figure 2 A structural schematic diagram of an integrated image control system provided in an embodiment of the present disclosure, the integrated image control system includes: a control backplane, an image server and an exposure control unit integrated on the control backplane, and the image server and the exposure control unit are connected through a mainboard bus.

[0037] In some embodiments, the control backplane is a control backplane designed based on the Compact Peripheral Component Interconnect (CPCI) standard.

[0038] The CPCI-based control backplane supports redundancy (providing reserved slots and other interfaces for connecting additional functional modules), offering flexible expansion capabilities. Furthermore, the CPCI-based control backplane supports high-speed bus connections between modules, providing greater stability and meeting the demands of rapid image data transmission and processing.

[0039] The exposure control unit is used to control the image acquisition device to acquire the target image.

[0040] Optionally, the target image may be an image including tumor information of the target object, for example, may include a target area.

[0041] For example, the target object may be a phantom, a human body, an experimental subject, an animal, etc. The target region may be a tumor region (also referred to as a region to be treated) of the target object.

[0042] Image acquisition equipment may include a tube, a beam splitter, a high-voltage generator, a flat panel, and other hardware devices used for image acquisition.

[0043] Optionally, the exposure control unit can control the image acquisition device to capture the target image based on the exposure timing. Exposure timing control refers to the precise time management of the action sequence of the various components of the image acquisition device during the image acquisition process to ensure the accuracy, stability, and synchronization of image acquisition.

[0044] The image server is used to receive and process target images captured by the image acquisition device.

[0045] Specifically, after capturing the target image, the image acquisition device can transmit the captured target image to the image server via the image local area network (LAN). The image server receives the target image sent by the image acquisition device and processes the target image, such as image reconstruction.

[0046] Exemplarily, the image server processing the target image may include: the image server combining the gantry angle data of the gantry during image acquisition (also known as the image acquisition angle) to reconstruct the target image to obtain a corresponding three-dimensional (3D) image, thereby facilitating subsequent analysis of the patient's tumor shape and position based on the 3D image.

[0047] Optionally, the image server may include a central processing unit (CPU), a graphics processing unit (GPU), and a communication module.

[0048] The CPU is the core computing unit of the image server, responsible for processing instructions, executing program logic, and controlling the coordinated operation of hardware devices. The GPU is used to process received target images. The GPU and CPU can be used in parallel computing scenarios, processing large amounts of data simultaneously. The communication module is used to interact with devices at other levels, such as receiving target images from image acquisition devices and sending processed target images to devices at higher levels.

[0049] Optionally, the communication module may be a 2.5G network card or other communication module.

[0050] The image server and the exposure control unit are connected via a mainboard bus, that is, the image server and the exposure control unit communicate via the mainboard bus.

[0051] In some embodiments, the motherboard bus includes: any one of a bus based on the high-speed serial computer expansion bus (Peripheral Component Interconnect Express, PCIe) standard, a bus based on the mesh network (Mesh Network, also known as Mesh networking) communication standard, a bus based on the Universal Serial Bus (USB) external bus standard, and a bus based on the Serial Advanced Technology Attachment (SATA) interface technology standard.

[0052] The motherboard bus can provide standardized protocols, high-speed transmission, flexible expansion and cross-platform compatibility, realizing a stable connection between the image server and the exposure control unit.

[0053] For example, the PCIe standard bus has the characteristics of high transmission speed, low latency, high scalability and high reliability. The bus based on the PCIe standard as a motherboard bus can achieve flexible hardware expansion and standardized compatibility.

[0054] Mesh networking uses a distributed topology, offering wide coverage, low cost, and easy scalability. Therefore, a bus based on the Mesh networking communication standard can implement modular expansion and other functions, and can be used for network communication between image servers and exposure control units.

[0055] The bus based on the USB external bus standard can support the flexible plug-in and unplugging of the image server and exposure control unit, greatly improving the flexibility of use. The bus based on the SATA interface technology standard can achieve high-speed and stable data transmission, and has the characteristics of an error checking mechanism to ensure the accuracy of data transmission between the image server and exposure control unit.

[0056] As can be seen from the above, when performing image reconstruction, the image server typically needs to obtain the acquisition angle corresponding to each target image. In other words, the image server needs to obtain the gantry angle of the gantry where the image acquisition device was located when capturing the target image. In this case, the radiotherapy system typically also includes an angle sensor to capture the gantry angle.

[0057] In general technology, such as Figure 1 As shown, the rack angle data collected by the angle sensor in real time is transmitted to the image server via the main controller and the IGS controller. Under this control mode, due to the long transmission link of the rack angle data, when the exposure control unit triggers the rack angle data collection and image information collection at the same time, the real-time data of the rack angle has not yet been transmitted to the IGS controller, resulting in the rack angle data recorded by the IGS controller being the historical data of the rack angle rather than the real-time data of the rack angle, further resulting in the rack angle data transmitted by the IGS controller to the image server being the historical data of the rack angle rather than the actual rack angle, which will cause the rack angle collection and image collection to be out of sync, thereby resulting in a decrease in image quality.

[0058] Based on the above problems, the integrated image control system provided by the embodiment of the present disclosure can integrate the angle sensor into the exposure control unit. Figure 2As shown, the exposure control unit integrates an angle sensor. This sensor is used to detect the rack angle of the rack where the image acquisition device is located. The image server is also used to obtain the rack angle captured by the angle sensor and process the target image captured by the image acquisition device based on the rack angle.

[0059] From the above, it can be seen that by integrating the angle sensor into the exposure control unit, when the exposure control unit simultaneously triggers the rack angle data acquisition and image information acquisition, the exposure control unit can promptly obtain the rack angle acquired by the angle sensor, so as to achieve precise synchronization of the rack angle acquisition and image acquisition, thus avoiding the problem of asynchronous rack angle acquisition and image acquisition in general technology.

[0060] Alternatively, the angle sensor can be integrated into the same control backplane as the exposure control unit and connected to the exposure control unit via a bus. Integrating the angle sensor and exposure control unit onto the same control backplane can also address issues such as low rack angle data transmission efficiency in conventional technologies.

[0061] In some embodiments, as Figure 2 As shown, the exposure control unit further includes a field programmable gate array (FPGA). The exposure control unit is used to control the image acquisition device to acquire the target image based on the FPGA.

[0062] Specifically, the exposure control unit may send an exposure control signal to the image acquisition device via the FPGA, thereby controlling the image acquisition device to acquire the target image via the FPGA.

[0063] As a programmable logic device, FPGAs offer high-speed parallel processing capabilities and flexible hardware programming. They allow for customizable timing logic and interface protocols, making them suitable for control scenarios requiring high real-time performance. In the disclosed embodiments, using FPGAs to control image acquisition equipment to capture target images improves the real-time performance and efficiency of target image acquisition. Compared to some traditional serial transmission methods, this significantly increases data transmission speed and reduces latency during target image acquisition.

[0064] In some embodiments, since the angle sensor and FPGA are both integrated into the exposure control unit, the angle sensor and FPGA can be connected via a board-level bus. The angle sensor is used to send the rack angle to the image server via the FPGA.

[0065] Optionally, since the communication method between the angle sensor and the FPGA may be different from the communication method between the FPGA and the image server, after receiving the rack angle sent by the angle sensor, the FPGA can convert the rack angle into the format of the communication protocol and send the rack angle after format conversion to the image server, so that the image server can quickly and accurately parse the rack angle.

[0066] In some embodiments, the FPGA and the image acquisition device may be connected via a board-level bus.

[0067] Connecting the image acquisition device and FPGA through a board-level bus can achieve module integration, reduce wiring complexity, and save space between boards.

[0068] The board-level bus includes any one of a Controller Area Network (CAN) bus, a serial communication standard RS232 bus, and a Serial Peripheral Interface (SPI) bus.

[0069] Specifically, the CAN bus can be used to easily form a variety of topologies, such as linear topology, star topology, etc. The networking method can be flexibly selected according to factors such as the physical layout and communication requirements of the actual application scenario, which facilitates system integration and optimization.

[0070] Using a bus based on the RS232 serial standard, the communication protocol is simple and can quickly achieve communication connections between devices (or modules).

[0071] The SPI bus supports full-duplex communication, that is, data can be transmitted in both directions at the same time. Compared with some half-duplex or simplex communication buses, it can transmit more data per unit time, effectively improving communication efficiency. It is suitable for situations where large amounts of data need to be exchanged quickly (such as data interaction scenarios with peripherals such as high-speed memory chips and image sensors).

[0072] In some embodiments, the FPGA and the image acquisition device may also be connected via an input / output (I / O) interface.

[0073] Optionally, the integrated image control system may further include a power module to supply power to the image server and the exposure control unit.

[0074] The above content is a description of an integrated image control system that can be applied to a radiotherapy system. Figure 3 FIG. 1 shows a schematic diagram of the structure of a radiotherapy system provided by an embodiment of the present disclosure. Figure 3 As shown, the radiotherapy system includes: Figure 2The integrated image control system and rotating gantry are shown.

[0075] Among them, the integrated image control system is installed on the rotating frame.

[0076] It can be understood that since the integrated image control system includes an exposure control unit, an image server and an angle sensor, the integrated image control system is installed on a rotating rack. When the rack rotates, the exposure control unit, the image server and the angle sensor are in a relatively static state, thereby improving the stability of data transmission and device connection.

[0077] In some embodiments, combined Figure 1 , Figure 4 FIG. 2 shows another structural diagram of a radiotherapy system provided by an embodiment of the present disclosure. Figure 4 As shown, the radiotherapy system may include the above Figure 2 The integrated image control system and main controller are shown.

[0078] Specifically, the main controller can process the image acquisition instructions (such as parsing and packaging) in response to the received image acquisition instructions, and transmit the processed image acquisition instructions to the exposure control unit in the integrated image control system through the real-time bus, and complete the exposure timing control and rack angle acquisition through the exposure control unit.

[0079] The main controller is connected with the exposure control unit in the integrated image control system through a real-time bus.

[0080] It is understandable that the real-time bus has the characteristics of high real-time transmission, and the controller is connected to the exposure control unit in the integrated image control system through the real-time bus, which can improve the transmission rate of data (such as image acquisition instructions).

[0081] In some embodiments, the real-time bus includes any one of an Ethernet for Control Automation Technology (EtherCAT) bus, a Controller Area Network (CAN) bus, a Serial Real-Time Communication Specification (SERCOS) bus, and a Modbus bus.

[0082] For example, the EtherCAT bus utilizes distributed clock synchronization technology, enabling clock synchronization with microsecond-level accuracy or even finer errors, minimizing the impact of time errors on data transmission. Furthermore, the EtherCAT bus offers advantages such as high-speed communication and high bandwidth utilization, which can increase data transmission rates. Furthermore, the EtherCAT bus supports a variety of topologies, allowing users to select the appropriate topology based on the actual module distribution, facilitating the connection of different types of devices.

[0083] The CAN bus offers advantages such as high reliability, multi-master communication, and low cost. The SERCOS bus can increase data transmission rates and enable hardware integration. The Modbus bus offers advantages such as simplified development and ease of integration.

[0084] Optionally, the image acquisition device may include a tube and a panel. The tube may emit kilovolt (KV) X-rays or megavolt (MV) X-rays. The panel may be a KV panel or an MV panel facing the tube.

[0085] In some embodiments, with the patient positioned on the support device of the radiotherapy device, the gantry's rotation can drive the tube to irradiate the patient 360 degrees. After the imaging radiation passes through the patient, it can be projected onto a flat panel, which then captures the projection data (i.e., the target image) from the tube. The flat panel then transmits the captured target image to an image server for image processing (e.g., reconstruction).

[0086] Optionally, the image acquisition device may further include a high voltage generator (HVGen), a motion motor (such as an MV Panel motion motor, a KV Panel motion motor), a beam splitter, and other hardware.

[0087] The HV Gen provides power to image acquisition equipment that generates X-rays and other radiation. The motion motor controls the movement of the flat panel (MV Panel or KV Panel) to the appropriate position for image acquisition. The beam splitter adjusts the shape and direction of the radiation emitted by the tube.

[0088] The above content is a description of the integrated image control system and the radiotherapy system, and then the image acquisition control method based on the radiotherapy system is introduced. Before introducing the image acquisition control method provided by the embodiment of the present disclosure, the general image acquisition control method is first introduced. Figure 5 As shown, based on Figure 1The general image acquisition control methods include:

[0089] S501. The main controller sends an image acquisition instruction to the exposure control unit through the IGS controller.

[0090] S502: The exposure control unit responds to the image acquisition instruction and sends an exposure control signal and a rack angle acquisition signal to the image acquisition device and the IGS controller at the same time.

[0091] S503 , the image acquisition device acquires the target image in response to the exposure control signal; the IGS controller acquires the rack angle in response to the rack angle acquisition signal.

[0092] S504: The image acquisition device sends the target image to the image server, and the IGS controller sends the rack angle to the image server.

[0093] S505: The image server performs image processing on the target image according to the target image and the rack angle.

[0094] As can be seen from the above, since the image server is typically installed outside the IGS electrical box, and the exposure control unit is installed inside the IGS electrical box, the exposure control unit typically sends exposure control signals to the image acquisition device via serial communication or input / output interfaces. This limits the transmission rate and reduces the reliability of the connection between the two when the rack rotates. Furthermore, since the rack angle must be transmitted to the image server via the main controller and IGS controller, the transmission link for rack angle data is long, resulting in asynchrony between rack angle acquisition and image acquisition, which in turn leads to reduced image quality.

[0095] In view of the above problems, the present disclosure provides an image acquisition control method. Figure 6 As shown, the image acquisition control method can be applied to the above Figure 2 The integrated image control system shown and Figure 3 or Figure 4 The radiation therapy system shown. The method includes:

[0096] S601: The main controller sends an image acquisition instruction to the exposure control unit.

[0097] Accordingly, the exposure control unit can obtain the image acquisition instruction.

[0098] In an embodiment of the present disclosure, the image acquisition instruction may be directly transmitted from the main controller to the exposure control unit.

[0099] S602: The exposure control unit sends an exposure control signal to the image acquisition device in response to the image acquisition instruction, and controls the angle sensor to acquire the rack angle of the rack where the image acquisition device is located.

[0100] The exposure control signal sent to the image acquisition device is used to instruct the image acquisition device to acquire a target image.

[0101] S603: The image acquisition device acquires a target image in response to the exposure control signal; the exposure controller receives the rack angle acquired by the angle sensor.

[0102] The specific process of image acquisition equipment acquiring target images can be referred to Figure 2 The description of how the image acquisition device acquires the target image is omitted here.

[0103] Since the exposure control unit provided in the embodiment of the present disclosure is integrated with an angle sensor, the exposure control unit can directly obtain the rack angle data collected by the angle sensor.

[0104] S604: The image acquisition device sends the target image to the image server, and the exposure controller sends the rack angle to the image server.

[0105] Optionally, the tablet in the image acquisition device can be connected to the image server. After acquiring the target image, the tablet in the image acquisition device can send the target image to the image server via the image LAN.

[0106] Optionally, as can be seen from the above description, the exposure control unit further integrates an FPGA. The FPGA is in communication with the angle sensor, and the exposure control unit can send the rack angle to the image server via the FPGA.

[0107] S605: The image server performs image processing on the target image according to the target image and the rack angle.

[0108] Optionally, since the target image is a single image, a 3D image may be required during the image guidance process. Therefore, the above steps can be repeated to obtain multiple target images at different angles, so that the image server can perform 3D reconstruction of the target image.

[0109] The image acquisition method provided by the embodiment of the present disclosure directly sends image acquisition instructions to the exposure control unit through the main controller, omitting the setting of the IGS controller in the general technology, simplifying the image acquisition control system, and shortening the image acquisition link; at the same time, the angle sensor is integrated into the exposure control unit, improving the synchronization between image acquisition and rack angle acquisition, and ensuring image quality.

[0110] The above mainly introduces the solution of the embodiment of the present disclosure from the perspective of method. It can be understood that, in order to realize the above functions, the exposure control unit includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiment disclosed herein, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software.

[0111] The disclosed embodiments can divide the exposure control unit into functional units based on the above-described method examples.
