[0002] X-ray imaging technology is an indispensable tool in modern medical diagnosis, industrial non-destructive testing, and other fields. As the core component of an X-ray imaging system, the performance and structure of the radiation source (usually an X-ray tube) directly affect image quality, equipment reliability, and operating costs.
[0003] Currently, X-ray imaging equipment generally uses a single-tube X-ray source structure, which is difficult to meet the needs of multi-angle, dual-energy, or rapid alternating imaging. Using two independent systems results in large size, high cost, and easy mutual interference; while attempting to integrate dual-ray output within a single high-voltage system faces practical problems such as complex circuitry, insulation difficulties, poor heat dissipation, and lack of independent control, which restricts the practical development of dual-source technology.

[0014] As a further aspect of the present invention: the X-ray generating mechanism has its X-ray tubes arranged in parallel along the length or width of the housing.
[0015] As a further aspect of the present invention: the high-voltage transformer and the filament transformer in the radiation generating mechanism are arranged side by side on one or both sides of their corresponding X-ray tube.
[0016] As a further aspect of the present invention: the back pressure sampling plates of the two X-ray generating mechanisms are respectively disposed in the box body at the side wall position adjacent to the corresponding X-ray tube.
[0017] As a further aspect of the present invention, it also includes an external control system, which is connected to the control terminal of each ray generating mechanism via an adapter plate to send independent exposure control signals to each ray generating mechanism.
[0018] As a further aspect of the present invention, the external control system can only send an exposure signal to one ray generating mechanism to ensure that at least two ray generating mechanisms do not perform exposure operations simultaneously.
[0019] The present invention also discloses a control method for a dual-tube X-ray source, applied to the dual-tube integrated X-ray source device described in any of the above claims, comprising the following steps: S10: Receives imaging commands from an external control system; S20: Based on the imaging command, determine the target ray generating mechanism to be activated in the current exposure cycle; S30: Sends an exposure enable signal to the target X-ray generating mechanism and controls its high-voltage transformer and filament transformer to operate so that the corresponding X-ray tube generates X-rays; S40: During the current exposure cycle, keep the other ray generating mechanism that is not the target in a non-exposure state; S50: After the current exposure cycle ends, switch the target ray generator and repeat the above steps to achieve alternating exposure between the two ray generators.

[0023] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves a compact design for dual radiation sources by integrating two complete radiation generating mechanisms (including an X-ray tube, a high-voltage transformer, a filament transformer, and a back-pressure sampling plate) into a single oil tank structure. Compared to the traditional approach of using two independent radiation source systems, this invention reduces the number of external housings, connectors, and auxiliary structures, simplifies the overall assembly process, lowers material and manufacturing costs, and effectively saves equipment installation space.
[0024] This invention, through independent electrical connections and control interfaces, enables two X-ray tubes to be exposed alternately under the strict control of an external system, with only one tube operating at any given time. This avoids electromagnetic interference, thermal coupling, and high-voltage crosstalk problems that may occur when two X-ray sources operate simultaneously, ensuring the purity and stability of the imaging signal and providing a reliable hardware foundation for advanced applications such as dual-energy imaging and multi-angle rapid scanning.
[0025] This invention employs a multi-layered insulation design for the high-voltage components of each X-ray generating mechanism: the back pressure sampling plate is isolated from the oil tank by being entirely encapsulated in an insulating box; the X-ray tube is covered with a dedicated insulating cover; and critical electrical connections are all treated with oil-impregnated insulation. This comprehensive insulation scheme significantly improves the partial discharge voltage threshold, effectively preventing breakdown and arcing under high-voltage conditions, and enhancing the safety and reliability of the equipment during long-term operation.
[0026] This invention utilizes the insulating oil filling the tank as a heat dissipation medium, and its compact layout allows the heat generated by the two X-ray tubes and transformer to be rapidly conducted into the oil. Because the two systems are integrated into the same oil circuit environment, the cooling oil volume is relatively larger, its heat capacity is higher, and the oil circulation or convection path is more optimized. Therefore, the overall heat dissipation efficiency is superior to two independent tank systems, which helps maintain the X-ray tubes and electronic components at suitable temperatures, extending their service life.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Before describing the technical solutions of each embodiment of the present invention in detail, the terms and terms involved will be explained. In this specification, components with the same name or the same reference numerals represent similar or the same structures, and are limited to illustrative purposes.
[0030] Example 1 like Figures 1 to 4 As shown, this embodiment proposes a dual-tube integrated X-ray source tank device, including a tank body 10, at least two X-ray generating mechanisms 20, an insulating component, and a heat dissipation medium. The X-ray generating mechanisms 20 are disposed inside the tank body 10, and the insulating component is disposed inside the tank body 10 to electrically isolate the high-voltage parts of the at least two X-ray generating mechanisms from the tank body 10. The heat dissipation medium is filled inside the tank body 10. The at least two X-ray generating mechanisms can be independently controlled to achieve alternating operation. In operation, the two X-ray generating mechanisms 20 work alternately under independent commands from the control system. When one X-ray generating mechanism 20 is activated, its filament transformer 230 heats the corresponding X-ray tube 210 cathode to emit electrons, and the high-voltage transformer 220 applies high voltage to accelerate the electron beam to bombard the anode target surface, thereby generating X-rays. During this process, the insulating components, through structures such as the insulating box 40 and the insulating cover 50, ensure reliable isolation between the high-potential components and the grounded oil tank shell; the heat dissipation medium filling the oil tank can absorb and evenly dissipate the heat generated during operation. After the exposure of the X-ray generating mechanism 20 is completed, the control system switches to the other X-ray generating mechanism 20, thus achieving alternating output of the dual X-ray sources in a cyclical manner. By integrating the dual X-ray generating mechanisms 20 into a single oil tank and using a multi-layer insulation and oil-immersion heat dissipation design, while significantly saving space and cost, electrical isolation and independent controllable alternating operation of the two X-ray sources are achieved, thereby solving the problems of complex structure, mutual interference, insufficient heat dissipation, and insulation safety risks existing in traditional dual-source systems.
[0031] The oil tank body 10 includes a housing 110, a cover plate 120 disposed on the top of the housing 110, and a transition plate 130 disposed on the cover plate 120. The housing 110 provides installation space and mechanical support for the functional components of the equipment. The cover plate 120 and the housing 110 cooperate through a sealing structure to form a sealed oil cavity, preventing the leakage of insulating oil and isolating the external environment. The transition plate 130 serves as the mechanical and electrical interface between the oil tank and external equipment such as control systems, power supplies, and support frames, enabling reliable transmission of signals, power, and fixed supports.
[0032] like Figures 1 to 4 As shown, in a preferred embodiment, based on the above method, a pressure balancing component is further provided inside the housing 110. The pressure balancing component is used to balance the pressure fluctuation inside the oil tank body 10 caused by the temperature change of the heat dissipation medium. The pressure balancing component is a breathing bag 30 located inside the cover plate 120 and in the upper space of the housing 110. The heat dissipation medium is insulating oil. During operation, the insulating oil inside the tank absorbs heat from the X-ray tube 210 and the transformer, causing its temperature to rise and its volume to expand, resulting in increased internal pressure. At this time, the breathing bag 30, fixed inside the tank cover 120 and located in the upper space of the tank body 110, actively absorbs or compensates for the volume change of the oil through the contraction or expansion of its flexible bladder. This automatically regulates and balances the internal pressure of the tank, preventing excessive pressure from causing seal failure or excessive pressure from introducing external air. The insulating oil simultaneously performs the dual functions of insulation and heat dissipation, ensuring the safety of the internal high voltage and efficiently transferring heat. By combining the flexible breathing bag 30 with the insulating oil medium, a reliable and adaptive pressure regulation capability is provided for the closed tank system, thus solving the problem of internal pressure fluctuations caused by temperature cycling and facilitating an increase in the lifespan of the sealing system.
[0033] like Figures 1 to 4 As shown, in a preferred embodiment, based on the above method, the X-ray generating mechanism 20 further includes an X-ray tube 210 for generating X-rays, a high-voltage transformer 220 for providing high-voltage electrical energy to the X-ray tube 210, a filament transformer 230 for providing heating current to the cathode of the X-ray tube 210, and a back pressure sampling plate 240 for sampling electrical signals. The X-ray tube 210, the high-voltage transformer 220, the filament transformer 230, and the back pressure sampling plate 240 are all disposed inside the housing 110. The high-voltage transformer 220 and the filament transformer 230 in the X-ray generating mechanism 20 are electrically connected to the corresponding X-ray tube 210 through high-voltage cables and low-voltage cables, respectively. Each X-ray generating mechanism 20 constitutes a complete and independent X-ray generation link. During operation, the filament transformer 230 supplies power to the cathode filament of the corresponding X-ray tube 210 via a low-voltage cable, heating it and causing it to emit thermionic electrons. Simultaneously, the high-voltage transformer 220 applies a DC high voltage of tens to hundreds of kilovolts between the anode and cathode of the X-ray tube 210 via a high-voltage cable. Under the influence of the strong electric field, the electrons emitted by the cathode are accelerated and bombard the anode target surface at high speed, thereby generating X-rays. The back pressure sampling board 240 can monitor the key electrical parameters of this high-voltage circuit in real time, providing feedback signals for system control. Each X-ray generating mechanism 20 is connected by independent cables, ensuring dedicated electrical power and signal integrity. Each X-ray generating mechanism is equipped with a complete and physically independent power supply and signal sampling link, enabling the dual-X-ray tube system integrated in the same tank to achieve electrical decoupling and independent control, thereby solving the problems of energy crosstalk and signal coupling between the two sources.
[0034] like Figures 1 to 4As shown, in a preferred embodiment, based on the above method, the insulation component further includes a first insulation component corresponding to each back pressure sampling plate 240 and a second insulation component corresponding to each X-ray tube 210; the first insulation component is an insulation box 40, which is fixedly installed on the inner wall of the housing 110, and the back pressure sampling plate 240 is disposed inside the insulation box 40; the second insulation component is an insulation cover 50, which covers the outer surface of the X-ray tube 210 and isolates the body of the X-ray tube 210 from the housing 110 and the insulating oil; High-voltage components within the tank are selectively isolated using a tiered and zoned approach. The back-pressure sampling board 240, which carries the high-voltage sampling circuit, is completely encapsulated within an insulating box 40 fixed to the tank wall, achieving physical isolation between this precision circuit and the grounding tank and surrounding electric field. The high-voltage core X-ray tube 210 is fully covered by an insulating cover 50 that closely conforms to its shape, with only necessary openings at the X-ray exit and electrical contacts. This establishes a high-voltage-resistant solid insulating barrier between the metal casing of the X-ray tube 210 and the grounding tank and cooling oil. The synergistic effect of these two levels of insulation components improves the creepage distance and electrical strength between the high-voltage components and ground. This prevents partial discharge, avoids high-voltage breakdown, and ensures the system's safety under long-term high-voltage operation.
[0035] It should be noted that the X-ray tubes 210 in the X-ray generating mechanism 20 are arranged parallel to each other along the length or width of the housing 110; the high-voltage transformers 220 and filament transformers 230 in the X-ray generating mechanism 20 are arranged side by side on one or both sides of their corresponding X-ray tubes 210; the two X-ray tubes 210 are arranged parallel to each other along the major or minor axis of the tank housing 110, providing a clear and fixed exit direction and spatial orientation for the two X-ray beams. The high-voltage transformers 220 and filament transformers 230 required for each X-ray tube 210 are arranged side by side adjacent to it. This compact layout of "one supporting two" or "distributed on both sides" minimizes the length of the high-voltage and low-voltage cables connecting each transformer to the corresponding X-ray tube 210, which not only reduces energy loss and voltage drop on the line and improves power conversion efficiency, but also reduces parasitic parameter interference and layout disorder problems that may be caused by excessively long cables. The overall layout takes into account both space utilization and electrical performance optimization.
[0036] Furthermore, the back pressure sampling plates 240 of the two X-ray generating mechanisms 20 are respectively located on the side wall adjacent to the corresponding X-ray tube 210 inside the housing 110; each back pressure sampling plate 240 is independently installed on the tank side wall near its corresponding X-ray tube 210. This proximity arrangement allows the sampling signal lines used to monitor key parameters of the high-voltage circuit (such as current and voltage) to be connected to the electrical port of the corresponding X-ray tube 210 via the shortest path. The shortened distance reduces the impedance in the signal transmission path and the possibility of introducing external electromagnetic interference, thereby ensuring the fidelity and real-time performance of the sampling signal and providing more accurate and faster high-voltage feedback for the control system. At the same time, the separate placement of components also avoids mutual interference that may occur if the two high-voltage sampling circuits are too close in space.
[0037] like Figures 1 to 4 As shown, in a preferred embodiment, based on the above method, the dual-tube integrated X-ray source tank device further includes an external control system. The external control system is connected to the control terminal of each X-ray generating mechanism 20 through the adapter plate 1 to send an independent exposure control signal to each X-ray generating mechanism 20. The external control system can only send an exposure enable signal to one ray generating mechanism 20 to ensure that at least two ray generating mechanisms 20 do not perform exposure operations at the same time; The external control system, acting as the central command unit, establishes independent communication and power supply links with the control terminals of the two X-ray generating mechanisms 20 via a dedicated electrical interface extending from the oil tank adapter plate 130. Based on preset imaging protocols or real-time commands, the system generates and sends precise timing control signals. Its core control logic is strictly configured in an "interlocked" mode, meaning that at any given moment, the system sends a high-voltage enable and filament heating signal to only one X-ray generating mechanism 20, triggering it to complete one exposure; while the other X-ray generating mechanism 20 remains in standby or completely de-energized. This process can be seamlessly alternated through high-speed electronic switches or software logic, ensuring that the two units operate completely out of time.
[0038] The present invention also discloses a control method for a dual-tube X-ray source, applicable to the dual-tube integrated X-ray source device in any of the above embodiments, comprising the following steps: S10: Receives imaging commands from an external control system; S20: Based on the imaging command, determine the target ray generating mechanism to be activated in the current exposure cycle; S30: Sends an exposure enable signal to the target X-ray generating mechanism and controls its high-voltage transformer and filament transformer to operate so that the corresponding X-ray tube generates X-rays; S40: During the current exposure cycle, keep the other ray generating mechanism that is not the target in a non-exposure state; S50: After the current exposure cycle ends, switch the target ray generator and repeat the above steps to achieve alternating exposure between the two ray generators.
[0039] Example 2 like Figures 1 to 4 As shown, the dual-tube integrated X-ray source oil tank device described in this embodiment also includes an oil tank body 10 forming a sealed oil chamber. The oil tank body 10 consists of a tank 110 and a cover plate 120 connected by a sealing structure, and is filled with insulating oil as a heat dissipation and insulation medium. A breathing bag 30 for balancing internal pressure is installed on the inner side of the cover plate 120, and an adapter plate 130 integrating electrical and mechanical interfaces is provided on the outer side. These basic designs ensure the environmental stability of the device operation and the convenience of external connection, and their principle and function are consistent with the aforementioned embodiments.
[0040] This embodiment deeply optimizes the refined layout, collaborative control strategy, and integrated energy management of the two sets of X-ray generating mechanisms 20 inside the housing 110. The two X-ray generating mechanisms 20 are not simply arranged side-by-side inside the housing 110, but rather adopt a "mirror-symmetric and functionally heterogeneous" integration method. Specifically, two X-ray tubes 210 are fixed parallel inside the housing 110, but their technical specifications or target materials can be configured differently to meet different imaging needs. For example, one X-ray tube 210 can be selected with high mA and relatively low kilovolt parameters, suitable for high-contrast imaging; the other can be selected with high kilovolt and relatively low mA parameters, suitable for low-contrast or high-penetration imaging. Each X-ray tube 210, its dedicated high-voltage transformer 220, filament transformer 230, and back pressure sampling plate 240 together constitute a functional unit, connected through optimized internal wiring.
[0041] To achieve efficient collaborative operation under this differentiated configuration, this embodiment features a meticulously designed electrical layout. The two sets of high-voltage transformers 220 and filament transformers 230 are not randomly placed, but rather positioned adjacent to their corresponding X-ray tubes 210, symmetrically arranged on both sides of the central axis of the enclosure 110. The high-voltage cables and filament cables connecting them are carefully arranged and fixed in dedicated cable trays to ensure the shortest path and minimal mutual interference. More importantly, two backpressure sampling plates 240 are respectively installed on the side walls of the enclosure 110 near their corresponding high-voltage transformers 220, and directly sample via shielded signal lines. This layout not only achieves physical electrical isolation but also makes each X-ray generating unit a nearly independent "sub-module," laying the hardware foundation for independent and collaborative control.
[0042] This embodiment's insulation scheme, while inheriting the dual protection concept of using an insulating box 40 to encapsulate the back pressure sampling board 240 and using an insulating cover 50 to cover the main body of the X-ray tube 210, strengthens the insulation against the complex electric field distribution that may result from "heterogeneous collaboration." Custom-shaped solid insulating baffles or insulating sleeves are added to the critical gap areas between the high-voltage ends of the two X-ray tubes 210 and between them and the grounding box 110. These additional insulating components further increase the creepage distance, optimize the electric field uniformity, and ensure that even when the two X-ray tubes 210 alternate or rapidly switch operation with different high-voltage parameters, there is no risk of partial discharge or insulation breakdown due to increased potential difference.
[0043] The core of this device's functionality lies in an external control system with advanced cooperative logic. This system, as in the aforementioned embodiment, not only sends independent exposure control signals to the two ray-generating mechanisms 20 and strictly ensures they do not expose simultaneously, but also executes complex "cooperative imaging protocols." The control system connects to each mechanism via an adapter board 130, which integrates a programmable timing generator and energy management algorithm. In practical applications, the operator can select multiple operating modes: 1. Standard Alternating Mode: Similar to traditional dual-tube CT, the two tubes 210 alternate exposure with a fixed timing and the same parameters to improve temporal resolution or expand coverage.
[0044] 2. Energy Complementary Mode: The system controls two X-ray tubes 210 with different parameters to alternately expose in a "high-low energy" sequence. For example, in a single rotational acquisition, the high-kilovolt X-ray tube exposure is triggered first, followed immediately by the low-kilovolt X-ray tube exposure, thereby quickly acquiring projection data of the same area under different X-ray energy spectra, providing a hardware foundation for energy-spectral CT or material separation imaging.
[0045] 3. Time-sharing and zone-based mode: The exposure time and dose of the two X-ray tubes 210 are dynamically allocated according to the importance of the scanned area. For example, the X-ray tube in high-dose, high-resolution mode is used for fine scanning of the region of interest, while the X-ray tube in fast, low-dose mode is used for coverage of non-critical areas, achieving optimal allocation of dose and image quality.
[0046] During these modes, the control system, based on a preset protocol, not only precisely controls the exposure sequence but also performs closed-loop fine-tuning of the high voltage and filament current of each X-ray tube 210 through real-time feedback from the back pressure sampling plate 240, ensuring the stability and accuracy of the output X-ray energy. The cooling system operates continuously, with insulating oil evenly absorbing the heat generated by the two X-ray tubes 210 and their transformers, and dissipating it through the walls of the enclosure 110. The breathing bag 30 dynamically maintains stable internal pressure, ensuring long-term operational reliability in all collaborative working modes.
[0047] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
