Technical Field
[0001] This invention relates to the field of high-end medical equipment technology, and in particular to a radiotherapy room. Background Technology
[0002] Medical equipment installed in medical rooms includes devices that emit radiation, such as X-ray machines, CT (Computed Tomography) machines, and particle therapy equipment. For safety reasons, the entire medical room needs to be designed with radiation shielding. Traditional medical rooms typically use reinforced concrete structures and lead for shielding. However, the construction period for concrete structures is long, and the range of applicable equipment after completion is not wide enough to meet the needs of rapid construction or adjustment of modern medical rooms. Summary of the Invention
[0003] The purpose of this invention is to provide a radiotherapy room that facilitates rapid construction and dismantling while meeting the requirements for radiation protection.
[0004] The objective of this invention is achieved through the following technical solution: a radiotherapy room, comprising:
[0005] The top frame is positioned opposite the ground.
[0006] The first frame is perpendicularly spliced to the top frame;
[0007] The second frame has an entrance and exit, and is positioned opposite to the first frame. The second frame and the top frame are vertically spliced together.
[0008] The third frame is perpendicularly spliced to the top frame, the first frame, and the second frame;
[0009] The fourth frame is arranged opposite to the third frame, and the fourth frame is perpendicularly spliced to the top frame, the first frame and the second frame respectively.
[0010] A shielding door mechanism, which is connected to the inner side of the second frame, is used to open or close the entrance / exit.
[0011] The top frame, the first frame, the second frame, the third frame and the fourth frame are all provided with a shielding layer on their outer sides. The top frame is provided with an air outlet and an air inlet that penetrate the shielding layer and are far apart from each other.
[0012] A receiving space; the receiving space is formed between the top frame, the first frame, the second frame, the third frame, the fourth frame, the shielding door mechanism and the ground, and is used to provide space for the installation of medical equipment and for patient treatment or examination;
[0013] A first shielding channel, one end of which is connected to the air inlet, and the other end of which is connected to the outside.
[0014] The second shielding channel has one end connected to the air outlet and the other end connected to the outside.
[0015] Compared with existing technologies, the advantages of the above technical solution are as follows: the detachable and modular frame structure, including a top frame, a first frame, a second frame, a third frame, and a fourth frame, not only meets the needs of constructing a radiotherapy room within an existing workshop or hospital, but also facilitates the rapid construction and dismantling of the radiotherapy room within the hospital or workshop, meeting the personalized customization needs of the radiotherapy room; the shielded door mechanism provides access while meeting radiation protection requirements; the shielding layer provides radiation protection for the entire frame structure, meeting the radiation protection requirements of the radiotherapy room; and the ingenious design of the shielded passage ensures that the radiotherapy room has radiation protection effects while providing ventilation. All of the above designs collectively meet the construction and radiation protection requirements of the radiotherapy room.
[0016] In some possible implementations, the shielding layer comprises a lead plate covered by a steel plate, the lead plate having a thickness of at least 5 mm and the steel plate having a thickness of at least 1.5 mm.
[0017] The beneficial effects of this embodiment are as follows: using lead plates as lead shielding, when the lead plate thickness is greater than or equal to 5mm, can effectively block radiation rays and prevent radiation leakage in the radiotherapy room, thus protecting human health. Using steel plates as the covering for lead shielding can provide good protection for lead shielding.
[0018] In some possible implementations, the air outlet and air inlet are both located diagonally on the top frame.
[0019] The beneficial effect of this embodiment is that the diagonal distribution of the air outlet and air inlet ensures a uniform distribution of airflow organization in the radiotherapy room, thereby improving the comfort of the radiotherapy room.
[0020] In some possible implementations, the radiotherapy room further includes an intermediate shielding plate disposed opposite to the top frame, with a space formed below the intermediate shielding plate for installing a control cabinet for controlling the medical equipment.
[0021] The beneficial effects of this embodiment are: while providing installation space for the control cabinet of the medical equipment below the intermediate shielding plate, the intermediate shielding plate also prevents the control cabinet from being affected by radiation, thus ensuring the normal operation of the control cabinet.
[0022] In some possible implementations, the first face frame includes:
[0023] A first fixed frame is provided, with a shielding layer welded to its outer side. The first fixed frame is perpendicularly spliced to the top frame, the third frame, and the fourth frame, respectively.
[0024] A first movable frame is provided with a detachable wall shielding component on its outer side. The first movable frame is spliced with the first fixed frame and is perpendicularly spliced with the third and fourth side frames respectively.
[0025] In some possible implementations, the wall shielding assembly includes a plurality of sub-shielding assemblies, the sub-shielding assemblies comprising:
[0026] A connecting frame, wherein the connecting frame is detachably connected to the first movable frame;
[0027] A shielding layer is disposed on the outside of the connecting frame and is detachably connected to the connecting frame.
[0028] The beneficial effects of this embodiment are that several sub-shielding components can be detachably assembled and disassembled on the first movable frame, which facilitates the construction of a radiotherapy room and makes it easy to replace and repair the sub-shielding components.
[0029] In some possible implementations, the connecting frame includes a first vertical square tube and a second vertical square tube that are parallel to each other, and a first horizontal square tube and a second horizontal square tube that are parallel to each other. The first horizontal square tube is perpendicularly connected to one end of the first vertical square tube and one end of the second vertical square tube, respectively. The second horizontal square tube is perpendicularly connected to the other end of the first vertical square tube and the other end of the second vertical square tube, respectively. At least one sub-square tube is erected between the first vertical square tube and the second vertical square tube along the length direction of the first vertical square tube and the second vertical square tube. The sub-square tube is parallel to the first horizontal square tube and the second horizontal square tube and is located between the first horizontal square tube and the second horizontal square tube. Reinforcing ribs are provided at the connection points between the first horizontal square tube and the first vertical tube, and between the second horizontal square tube and the second vertical square tube.
[0030] The beneficial effect of this embodiment is that the connection between the first horizontal square tube and the first vertical square tube, and between the second horizontal square tube and the second vertical tube is improved by reinforcing ribs.
[0031] In some possible implementations, the containment space includes a particle accelerator installation space and a CT scanner installation space, with the air outlet located adjacent to the particle accelerator installation space and the CT scanner installation space.
[0032] In some possible implementations, the sub-square tube has a first side and a second side, and a reinforcing rib is provided at the connection between the first side of the sub-square tube and the first vertical tube and the second vertical tube. A reinforcing member is provided at the connection between the second side of the sub-square tube and the first vertical tube and the second vertical tube. A plurality of hooks are provided on the reinforcing member. At least one connecting plate is provided on the first movable frame, and the hooks can be hung on the connecting plate.
[0033] In some possible implementations, the reinforcing rib and the shielding layer are connected by screws, the screws having a tip located inside the radiotherapy room and an end located outside, the tip being connected to a lead cap.
[0034] In some possible implementations, the opening directions of the first shielding channel and the second shielding channel are different.
[0035] In some possible implementations, the radiotherapy room further includes a bottom shielding plate for dividing the containment space into a first containment space and a second containment space in a top-to-bottom direction. The CT scanner installation space is located in the first containment space, and the first and second containment spaces together form the motion space of the particle accelerator.
[0036] In some possible implementations, both the first shielding channel and the second shielding channel include at least three sequentially bent and connected sub-shielding channels, and the included angle between two adjacent sub-shielding channels cannot be 180 degrees or 360 degrees.
[0037] The beneficial effect of this embodiment is that it ensures that when the radiated photons enter the first and second shielding channels with the air, they undergo at least two turns to attenuate the radiation, thus ensuring that the ventilation system of the radiotherapy room meets the requirements for radiation protection.
[0038] In some possible implementations, at least one lead glass window is provided on the shielding layer of the top frame, and at least one lead glass window is provided on the shielding layers of both the third and fourth frames.

[0059] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.
[0060] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.
[0061] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0062] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0063] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0064] In this invention, "vertical," "horizontal," and "parallel" are defined as cases within ±10% of the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to a baseline, but in this application, vertical refers to cases within 80 to 100 degrees.
[0065] See appendix Figure 1 and 2 As shown, this embodiment provides a radiotherapy room, including a top frame 1, a first frame 2, a second frame 3, a third frame 4, a fourth frame 5, a shielding layer, a shielding door mechanism 6, a first shielding passage 7, a second shielding passage 8, and a containment space, all disposed opposite to the ground. During use, the radiotherapy room may generate radioactive materials with radiation doses, such as photons, neutrons, and protons. The containment space is formed between the top frame 1, the first frame 2, the second frame 3, the third frame 4, the fourth frame 5, the shielding door mechanism 6, and the ground, providing space for the installation of medical equipment and for patient treatment or examination. The radiotherapy room may be simply referred to as a radiotherapy room. In some embodiments, the ground may be provided as a lead shielding plate, wherein the lead shielding plate is covered with a steel plate, the thickness of the lead shielding plate is at least 5 mm, and the thickness of the steel plate is at least 1.5 mm.
[0066] The top frame 1, first frame 2, second frame 3, third frame 4, and fourth frame 5 are all equipped with shielding layers on their outer sides. A penetrating shielding layer is installed on the top frame 1, and the frames are positioned far apart from the air outlets and inlets to ensure that the air entering through the inlets is not affected by the air or radioactive materials exiting through the outlets. Furthermore, the air outlets and inlets are diagonally positioned, ensuring a uniform distribution of airflow within the radiotherapy room and thus improving comfort.
[0067] One end of the first shielding channel 7 is connected to the air inlet, and the other end is connected to the outside. One end of the second shielding channel 8 is connected to the air outlet, and the other end is connected to the outside. The first shielding channel 7 prevents radiation from spreading to the outside when the ventilation system is intake, and the second shielding channel 8 prevents radiation from spreading to the outside when the ventilation system is exhaust. The design of the ventilation system meets the radiation protection requirements of the radiology medical room during ventilation, ensuring personnel safety.
[0068] Specifically, the first shielding channel 7 and the second shielding channel 8 can be constructed using shielding layers. Preferably, the opening directions of the first shielding channel 7 and the second shielding channel 8 are different to ensure better air circulation between the inside and outside of the radiotherapy room, and the air entering the first shielding channel 7 will not be affected by the air and radiation discharged from the second shielding channel 8.
[0069] The first frame 2 is perpendicularly joined to the top frame 1. The second frame 3, with an entrance / exit, is positioned opposite the first frame 2 and perpendicularly joined to the top frame 1. The third frame 4 is perpendicularly joined to the top frame 1, the first frame 2, and the second frame 3. The fourth frame 5 is opposite to the third frame 4 and perpendicularly joined to the top frame 1, the first frame 2, and the second frame 3. A shielding door mechanism 6 connects to the inner side of the second frame 3 and is used to open or close the entrance / exit.
[0070] The detachable and modular frame structure, comprising a top frame 1, a first frame 2, a second frame 3, a third frame 4, and a fourth frame 5, not only meets the needs of constructing a radiotherapy room within an existing workshop or hospital but also facilitates rapid construction and dismantling of the radiotherapy room within the hospital or workshop, satisfying the personalized customization requirements of radiotherapy rooms. The shielded door mechanism 6 provides access while also meeting radiation protection requirements. The shielding layer provides radiation protection for the entire frame structure, fulfilling the radiation protection requirements of the radiotherapy room. The clever structural and positional design of the shielded passageways and air inlets / outlets ensures that the radiotherapy room provides both ventilation and radiation protection. These designs collectively meet the construction requirements and radiation safety requirements of the radiotherapy room.
[0071] In some specific embodiments, the radiotherapy room also includes an intermediate shielding plate 11 disposed opposite to the top frame 1 and the ground, and located between the top frame 1 and the ground. A shielding layer is provided on the outer side of the intermediate shielding plate 11, and a space for installing a control cabinet is formed below the intermediate shielding plate 11. The control cabinet is used to control medical equipment. While providing installation space for the control cabinet of the medical equipment below the intermediate shielding plate 11, the shielding layer on the outer side of the intermediate shielding plate 11 prevents the control cabinet from being affected by radiation, ensuring the normal operating performance of the control cabinet.
[0072] In some specific implementations, the shielding layer includes a lead plate covered by a steel plate. The lead plate has a thickness of at least 5 mm, and the steel plate has a thickness of at least 1.5 mm. The steel plate is in contact with the outside environment, providing overall strength for the radiology room, while the lead plate is in contact with the interior of the room, providing good radiation protection. Specifically, a lead plate thickness of 5 mm and a steel plate thickness of 1.5 mm can meet the basic protection requirements of a radiology room.
[0073] For some specific implementation methods, see the appendix. Figure 3 As shown, the first frame 2 includes a first fixed frame 20 and a first movable frame 21. A shielding layer is welded to the outside of the first fixed frame 20, and the first fixed frame 20 is perpendicularly spliced to the top frame 1, the third frame 4, and the fourth frame 5, respectively.
[0074] The outer side of the first movable frame 21 is provided with a detachable wall shielding component. The first movable frame 21 is spliced with the first fixed frame 20. The first movable frame 21 is spliced perpendicularly with the third frame 4 and the fourth frame 5 respectively. The first movable frame 21 corresponds to the particle accelerator, allowing the particle accelerator to be moved into or out of the containment space from below the first fixed frame 20, which facilitates the installation or subsequent replacement of the particle accelerator.
[0075] Furthermore, the containment space includes space for installing a particle accelerator and a CT scanner. Air outlets are located near these spaces to facilitate faster airflow and removal of radiation generated by the particle accelerator and CT scanner from the radiotherapy room. Additionally, medical equipment installed in the radiotherapy room includes particle radiotherapy equipment, such as proton therapy equipment, with the particle accelerator being a proton accelerator used to provide proton beams for tumor treatment.
[0076] Furthermore, a bottom shielding plate can be installed in the radiotherapy room to divide the containment space into a first containment space and a second containment space from top to bottom. The CT machine installation space is located in the first containment space. The first containment space and the second containment space together form the movement space of the particle accelerator, making the radiotherapy room compact and making full use of the internal space.
[0077] Specifically, the wall shielding assembly includes a plurality of sub-shielding assemblies, and each sub-shielding assembly includes a connecting framework 22 and a shielding layer. The connecting framework 22 is detachably connected to a first moving frame 21, and the shielding layer is disposed outside the connecting framework 22 and detachably connected to the connecting framework 22. Through the detachable connection between the connecting framework 22 and the first moving frame 21, and the detachable connection between the shielding layer and the connecting framework 22, while meeting the radiation protection requirement of the first surface frame 2 of the radiology medical room, the convenience of disassembly can also be achieved, facilitating rapid construction and maintenance.
[0078] In some specific implementations, referring to the attached Figure 5 as shown, the connecting framework 22 includes a first vertical square tube 220 and a second vertical square tube 221 that are parallel to each other, and a first horizontal square tube 222 and a second horizontal square tube 223 that are parallel to each other. The first horizontal square tube 222 is perpendicularly connected to one end of the first vertical square tube 220 and one end of the second vertical square tube 221 respectively, and the second horizontal square tube 223 is perpendicularly connected to the other end of the first vertical square tube 220 and the other end of the second vertical square tube 221 respectively. At least one sub square tube 224 is erected between the first vertical square tube 220 and the second vertical square tube 221 along the length direction of the first vertical square tube 220 and the second vertical square tube 221. In this embodiment, two sub square tubes 224 are provided. The sub square tubes 224 are parallel to the first horizontal square tube 222 and the second horizontal square tube 223 and located between the first horizontal square tube 222 and the second horizontal square tube 223, so that the entire connecting framework 22 presents a "grid" shape. The arrangement of the sub square tubes 224 improves the connection stability of the entire connecting framework 22.
[0079] In some specific embodiments, reinforcing ribs are provided at the joints between the first horizontal square tube 222 and the first vertical square tube 220, and between the second horizontal square tube 223 and the second vertical square tube 221. The arrangement of the reinforcing ribs is to improve the connection stability between the first horizontal square tube 222 and the first vertical square tube 220, as well as between the second horizontal square tube 223 and the second vertical square tube 221, and further ensure the stability of the overall framework.
[0080] In some specific embodiments, the sub square tube 224 has opposite first side and second side. Reinforcing ribs are provided at the joints between the first side of the sub square tube 224 and the first vertical square tube 220 as well as the second vertical square tube 221, and reinforcing members 225 are provided at the joints between the second side of the sub square tube 224 and the first vertical square tube 220 as well as the second vertical square tube 221. The reinforcing ribs and the reinforcing members 225 are used to improve the connection stability between the sub square tube 224 and the first vertical square tube 220 and the second vertical square tube 221 respectively, and further ensure the stability of the overall framework.
[0081] In some specific implementations, referring to the attached Figure 4As shown, the reinforcing member 225 is provided with several hooks 226, and the first movable frame 21 is provided with at least one connecting plate 227. The hooks 226 can be hung on the connecting plate 227. Through the connection of the hooks 226 and the connecting plate 227, the detachable splicing of the connecting frame 22 and the first movable frame 21 can be realized, which is conducive to the rapid construction and maintenance of the medical room.
[0082] In some specific implementations, the reinforcing rib and the shielding layer are connected by screws, which include a tip located inside the radiology room and an end located outside, with the tip connected to a lead cap. The screws improve the stability of the connection between the reinforcing rib and the shielding layer, and the lead caps prevent radiation from diffusing to the outside through the screws inside the radiology room.
[0083] In some specific embodiments, both the first shielding channel 7 and the second shielding channel 8 include at least three sequentially bent and connected sub-shielding channels 9, and the included angle between two adjacent sub-shielding channels 9 cannot be 180 degrees or 360 degrees. See Appendix Figure 1 and 2 As shown, the first shielding channel 7 includes four sub-shielding channels 9 that are perpendicularly connected to each other, and a fan for air intake is installed inside. The second shielding channel 8 includes four sub-shielding channels 9 that are perpendicularly connected to each other, and a fan 12 for air exhaust is installed inside.
[0084] Radiation refers to the phenomenon where a portion of the electromagnetic energy emitted by a source (such as electromagnetic waves) escapes from the source and propagates to a distance without returning. This energy diffuses outward in the form of electromagnetic waves or particles (such as alpha particles and beta particles). Radiation from a radiotherapy room can spread to the outside world and pose a threat to human health. When the ventilation system of a radiotherapy room is operating, an angle is cleverly designed at the bends and connections of multiple sub-shielded channels. This causes radiation-producing particles such as photons, neutrons, and protons to collide with the inner walls of the channels during the bends, resulting in attenuation of radiation and significantly reducing its spread to the outside through the ventilation system.
[0085] The more sub-shielding channels 9 there are, the more times that radiation-generating particles collide with the inner wall of the channel when turning, resulting in attenuation, until radiation is eliminated or radiation protection requirements are met. Specifically, the radiation protection effect is best when the included angle is 90 degrees or 270 degrees, and the number of sub-shielding channels 9 is also the least.
[0086] In some specific embodiments, at least one lead glass window 10 is provided on the shielding layer of the top frame 1, and at least one lead glass window 10 is provided on the shielding layers of the third frame 4 and the fourth frame 5. Considering the lighting requirements of radiotherapy rooms constructed within existing workshops or hospital buildings, the lead glass window 10 on the shielding layer facilitates the assembly and construction of the radiotherapy room in the workshop, while also providing good radiation protection during use in the radiotherapy room.
[0087] For some specific implementation methods, see the appendix. Figure 6 As shown, the second frame 3 includes a first side frame 31, a second side frame 32, a second fixed frame 33, and a shielding door mechanism 6. A shielding layer is welded to the outer side of the first side frame 31, and the first side frame 31 is detachably and perpendicularly connected to the top frame 1 and the fourth frame 5, respectively. A shielding layer is welded to the outer side of the second side frame 32, and the second side frame 32 is detachably and perpendicularly connected to the top frame 1 and the third frame 4, respectively.
[0088] The second fixed frame 33 has a first end and a second end opposite to each other. The first end of the second fixed frame 33 and the first side frame 31 are detachably connected. The second end of the second fixed frame 33 and the second side frame 32 are detachably connected. The second fixed frame 33 has an inlet and an outlet. A shielding layer is welded to the outside of the second fixed frame 33.
[0089] The shielding door mechanism 6 includes two movable shielding doors 60. The two movable shielding doors 60 open or close the entrance and exit by moving in opposite directions. One end of the movable shielding door 60 is connected to the inner side of the first side frame 31, and the other end of the movable shielding door 60 is connected to the inner side of the second side frame 32.
[0090] The entrance and exit are opened or closed by two movable shielding doors 60 in a doubly movable manner, which facilitates the entry and exit of doctors and patients into and out of the medical room. The shielding layer is set to meet the radiation protection requirements of the radiology medical room. The detachable connection of the above components is to facilitate the rapid construction, maintenance and disassembly of the radiology medical room.
[0091] In some implementations, see Appendix Figure 7 As shown, the movable shielding door 60 includes a lead door 601, a drive mechanism 602 (preferably a servo drive motor), a drive gear 603, a rack 604, a slide bar 605, and a pulley 606. The drive gear 603 is connected to the output end of the drive mechanism 602; the rack 604 is mounted on the lead door 601 and meshes with the drive gear 603; the slide bar 605 is connected to the inner side of the first side frame 31 or the second side frame 32; the pulley 606 is mounted on the lead door 601 and is slidably connected to the slide bar 605.
[0092] The working principle of the movable shielding door 60 is as follows: the servo drive motor drives the drive gear 603 to rotate. Due to the meshing relationship between the drive gear 603 and the rack 604, the rack 604 moves axially while the drive gear 603 remains stationary. Due to the connection between the rack 604 and the lead door 601, the lead door 601 can move axially on the slide rod 605 via the pulley 606. Thus, the two movable shielding doors 60 open or close the entrance and exit by moving in opposite directions while moving synchronously.
[0093] The opening process of the left-side movable shielding door 60 is as follows: The servo drive motor drives the drive gear 603 to rotate clockwise. Due to the meshing relationship between the drive gear 603 and the rack 604, the rack 604 moves axially in the first direction while the drive gear 603 remains stationary. Due to the connection between the rack 604 and the lead door 601, the lead door 601 can move axially in the first direction on the slide rod 605 via the pulley 606, thus realizing the opening of the left side door.
[0094] The opening process of the right-side movable shielding door 60 is as follows: A servo drive motor drives the drive gear 603 to rotate counterclockwise. Due to the meshing relationship between the drive gear 603 and the rack 604, while the drive gear 603 remains stationary, the rack 604 moves in a second axis opposite to the first axis. Because of the connection between the rack 604 and the lead door 601, the lead door 601 can move in a second axis on the slide rod 605 via the pulley 606, thus opening the door on the right side. Both mechanisms work simultaneously to achieve full opening.
[0095] The closing process of the left-side movable shielding door 60 is as follows: The servo drive motor drives the drive gear 603 to rotate counterclockwise. Due to the meshing relationship between the drive gear 603 and the rack 604, the rack 604 moves in the second axis while the drive gear 603 remains stationary. Due to the connection between the rack 604 and the lead door 601, the lead door 601 can move in the second axis on the slide rod 605 via the pulley 606, thus closing the left side door.
[0096] The closing process of the right-side movable shielding door 60 is as follows: A servo drive motor drives the drive gear 603 to rotate clockwise. Due to the meshing relationship between the drive gear 603 and the rack 604, the rack 604 moves in the first axial direction while the drive gear 603 remains stationary. Because of the connection between the rack 604 and the lead door 601, the lead door 601 can move in the first axial direction on the slide rod 605 via the pulley 606, thus opening the door on the right side. Both mechanisms work simultaneously to achieve complete closing.
[0097] In summary, the two movable shielding doors 60 can open or close the entrance / exit by moving in opposite directions, provided that they move synchronously. Alternatively, they can operate independently to achieve single-sided opening and closing.
[0098] Furthermore, in some specific implementations, to prevent radiation leakage at the joint between the walls and the floor of the radiology room, shielding lead plates with a thickness of 5mm are installed around the floor of the radiology room, close to the inner wall of the radiology room. The upper surface of the lead plate is covered with a 1.5mm steel plate to prevent the lead plate from being exposed.
[0099] Furthermore, in some specific embodiments, the third frame 4 is also provided with a lead-shielded door 13 for maintenance. When the lead-shielded door 13 is open, the radiation equipment in the radiation therapy room stops working; when the lead-shielded door 13 is closed, the radiation equipment in the radiation therapy room can work. Furthermore, in some specific embodiments, the connection gaps in the radiation therapy room during construction are made of lead plates as overlaps.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
