It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] A CT frame generally includes a fixed part, a rotating part and a bearing, and the rotating part is mounted on the fixed part through the bearing. The rotating part carries a radiation source and a detector for emitting an X-ray beam. The X-ray beam is captured by the detector after passing through the human body. The computer reconstructs the image based on the signal captured by the detector to obtain an image of a specific part of the human body. In actual applications, the fixed part, the rotating part and the bearing all occupy a large space and are heavy. However, the load-bearing and accommodation space of the transportation equipment (such as hospital elevators) used to transport the CT frame are limited, making it difficult to transport the CT frame.

[0035] In order to solve the above problems, an embodiment of the present application provides a CT gantry, by dividing a fixed part 100 into a separable first base body 110 and a second base body 120, when transporting the CT gantry, the rotating part 200 can be separated from the bearing 300, the bearing 300 is installed by the first base body 110, and the rotating part 200 is supported by the second base body 120, so that the CT gantry can be divided into two parts for transportation separately, thereby reducing the difficulty of transporting the CT gantry.

[0036] Please also read Figures 1 to 3 , the CT gantry provided by the embodiment of the present application is now described in detail. The CT gantry includes a fixed part 100, a rotating part 200 and a bearing 300; the fixed part 100 includes a first seat body 110 and a second seat body 120 that are detachably connected; the bearing 300 is installed on the first seat body 110, the rotating part 200 is detachably connected to the rotor of the bearing 300, and the second seat body 120 is used to support the rotating part 200 after being separated from the bearing 300.

[0037] The fixing portion 100 includes a first base body 110 and a second base body 120 that are detachably connected. The first base body 110 and the second base body 120 can be connected together to form the fixing portion 100 , and the first base body 110 and the second base body 120 can also be separated from each other.

[0038] The bearing 300 is mounted on the first seat body 110, specifically, the stator of the bearing 300 is mounted on the first seat body 110, and the rotating part 200 is connected to the rotor of the bearing 300. When the rotating part 200 is driven to rotate, the rotating part 200 and the rotor of the bearing 300 rotate together relative to the stator of the bearing 300 and the first seat body 110. In addition, the rotating part 200 can also be separated from the rotor of the bearing 300.

[0039] The second seat body 120 is used to support the rotating part 200 after it is separated from the bearing 300. Specifically, when the rotating part 200 is connected to the bearing 300, the rotating part 200 is supported by the bearing 300 and the first seat body 110; when the rotating part 200 is separated from the bearing 300, the second seat body 120 supports the rotating part 200. In addition, the number of the rotating parts 200 can be one or two, and the second seat body 120 is only used to support the rotating part 200 corresponding to its position and separated from the bearing 300, while the rotor that is not separated from the bearing 300 continues to be supported by the first seat body 110.

[0040] After the CT gantry is assembled, the first base body 110 and the second base body 120 are connected to each other, the bearing 300 is installed on the first base body 110, the rotating part 200 is connected to the bearing 300, and the rotating part 200 rotates on the first base body 110 through the bearing 300; when the CT gantry is transported, the rotating part 200 is separated from the bearing 300, and the rotating part 200 separated from the bearing 300 is supported by the second base body 120, while the bearing 300 and the rotating part 200 that is not separated from the bearing 300 are always supported on the first base body 110, and the first base body 110 and the second base body 120 are transported separately.

[0041] In the embodiment of the present application, the fixed part 100 is split into a first seat body 110 and a second seat body 120 that are detachably connected, the bearing 300 is installed by the first seat body 110, and the rotating part 200 separated from the bearing 300 is supported by the second seat body 120. Specifically, during transportation, the rotating part 200 can be separated from the bearing 300, and then the rotating part 200 is supported by the second seat body 120, so that the rotating part 200 and the bearing 300 can be transported separately, reducing the transportation difficulty of the CT frame and improving the transportation convenience of the CT frame. At the same time, the present application supports the separated rotating part 200 by separating the second seat body 120 from the fixed part 100, thereby avoiding the need to set up an additional support frame to carry the separated rotating part 200, reducing the transportation cost and transportation assembly process of the fixed part 100. In addition, the rotating part 200 and the bearing 300 are transported separately, which can avoid the bearing 300 being damaged by the impact of transportation during transportation of the rotating part 200.

[0042] In one embodiment, see Figures 1 to 3 The CT gantry includes a rotating part 200 and a second base body 120. After assembly, the second base body 120 is connected to the first base body 110 to form the fixed part 100, and the rotating part 200 is installed on the bearing 300; during transportation, the rotating part 200 is separated from the bearing 300, the second base body 120 supports the rotating part 200, and the second base body 120 is separated from the first base body 110.

[0043] In another embodiment of the present application, the CT gantry includes two rotating parts 200 and two second base bodies 120. After assembly, the two second base bodies 120 are connected to opposite sides of the first base body 110 to form the fixed part 100, the two rotating parts 200 are respectively connected to the bearings 300 and are arranged at intervals along the axial direction of the bearings 300, and the two second base bodies 120 are respectively arranged corresponding to the two rotating parts 200; during transportation, the two rotating parts 200 are respectively separated from the bearings 300, the two second base bodies 120 respectively support the corresponding rotating parts 200, and the two second base bodies 120 are respectively separated from the first base body 110.

[0044] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The CT frame includes two rotating parts 200, namely a first rotating part 210 and a second rotating part 220. The first rotating part 210 and the second rotating part 220 are respectively connected to the bearing 300 and are arranged at intervals along the axial direction of the bearing 300; the fixed part 100 includes a second seat body 120, and the second seat body 120 is used to support the first rotating part 210 after being separated from the bearing 300.

[0045] After assembly, the first rotating part 210 and the second rotating part 220 are connected to the bearing 300 respectively, and the second seat body 120 is arranged corresponding to the first rotating part 210; during transportation, the first rotating part 210 is separated from the bearing 300, the first rotating part 210 is supported by the second seat body 120, and the second seat body 120 is separated from the first seat body 110, and the first rotating part 210 is transported together with the second seat body 120, while the second rotating part 220 continues to be installed on the first seat body 110 through the bearing 300 and is transported together with the first seat body 110. In this embodiment, when the CT frame includes two rotating parts 200, one of the rotating parts 200 and the second seat body 120 can be separated for separate transportation, which can also reduce the difficulty of transporting the entire CT frame, and there is no need to separate both rotating parts 200, which simplifies the structure of the fixed part 100.

[0046] In the above two rotating parts 200, please refer to Figure 6 The first seat body 110 is provided with a synchronizer 600, which is connected to the rotor of the bearing 300, and the opposite ends of the synchronizer 600 are respectively connected to the two rotating parts 200. The synchronizer 600 is used to connect the two rotating parts 200, thereby ensuring the rotation consistency of the two rotating parts 200, and also improving the installation reliability of the rotating part 200 on the first seat body 110.

[0047] Optionally, see Figure 6, two bearings 300 are provided on the first seat body 110, and a mounting hole is formed on the first seat body 110. The two bearings 300 are respectively installed in the mounting holes and are spaced apart along the axial direction of the mounting holes. The synchronizer 600 is respectively connected to the rotors of the two bearings 300, and the two rotating parts 200 are respectively connected to the opposite ends of the synchronizer 600. It can be understood that in other embodiments of the present application, one bearing 300 can also be installed on the first seat body 110, the synchronizer 600 is connected to the rotor of the bearing 300, and the two rotating parts 200 are respectively connected to the opposite ends of the synchronizer 600.

[0048] In one embodiment, see Figures 1 to 3 The CT frame also includes a connecting member 400, which is used to fix the rotating part 200 on the second base body 120. The connecting member 400 and the rotating part 200 are detachably connected. When assembling the CT frame, the connecting member 400 is separated from the rotating part 200; when transporting the CT frame, the rotating part 200 is first fixed to the second base body 120 through the connecting member 400, and then the rotating part 200 is separated from the bearing 300, and finally the second base body 120 is separated from the first base body 110, so that the second base body 120, the rotating part 200 and the connecting member 400 are fixed as a whole and can be transported separately.

[0049] The connecting member 400 can be fixed on the second base body 120, and the connecting member 400 can also be detachably connected to the second base body 120. When the connecting member 400 is fixed on the second base body 120, the connecting member 400 is always arranged following the second base body 120, and during transportation, it is only necessary to connect the connecting member 400 with the rotating part 200. When the connecting member 400 is detachably connected to the second base body 120, the connecting member 400 can be arranged separately when assembling the CT frame, and then during transportation, the connecting member 400 is connected to the second base body 120 and the rotating part 200 respectively to fix the rotating part 200 on the second base body 120.

[0050] In one embodiment, the number of the connecting members 400 is at least two, and at least two connecting members 400 connect different positions of the rotating part 200 to the second base body 120. The rotating part 200 is installed by at least two connecting members 400, so that the rotating part 200 is installed on the second base body 120 stably and securely.

[0051] In a specific embodiment, see Figure 1 and Figure 3The second base body 120 includes a bottom plate 121 and two side plates 122, the two side plates 122 are connected to opposite sides of the bottom plate 121 along the first direction X, and the two connecting members 400 are respectively connected between the two side plates 122 and the rotating part 200, specifically, the connecting member 400 is connected between the top of the side plate 122 and the rotating part 200. The first direction X is perpendicular to the axial direction of the rotating part 200, and the first direction X is perpendicular to the vertical direction. The second base body 120 in this embodiment is composed of a bottom plate 121 and two side plates 122 arranged at intervals along the first direction X, so that the second base body 120 has a simple structure and occupies a small space along the axial direction of the rotating part 200; and the second base body 120 and the rotating part 200 are respectively connected by two connecting members 400 along the first direction X, so that the connecting member 400 does not occupy the space of the CT frame along the first direction X, so that the connecting member 400 and the second base body 120 do not interfere with the driving mechanism of the rotating part 200. It can be understood that in other embodiments of the present application, the second base body 120 can also include a top plate, which is connected to the two side plates 122, and a connecting member 400 is provided on the top plate, and the connecting member 400 connects the top plate and the rotating part 200. In addition, in other embodiments, the number of connecting members 400 can also be three, four or more than four, which is not limited here.

[0052] In one embodiment, see Figure 1 The connecting member 400 includes a supporting portion 430 and a first connecting portion 410 and a second connecting portion 420 connected to opposite ends of the supporting portion 430. The first connecting portion 410 is connected to the second seat body 120, and the second connecting portion 420 is connected to the rotating portion 200. Specifically, the first connecting portion 410 is attached to the top end surface of the side plate 122 and is locked and fixed on the top end surface of the side plate 122; a mounting surface is formed on the rotating portion 200, and the second connecting portion 420 is attached to the mounting surface and is locked and fixed on the mounting surface. The setting of the supporting portion 430 can support and suspend the rotating portion 200, ensuring that the rotating portion 200 can be suspended and fixed between the two side plates 122 and the bottom plate 121.

[0053] See also Figure 1 The support portion 430 is tilted from the side plate 122 toward the rotating portion 200, so that the support portion 430 can be close to the rotating portion 200, making the layout of the connecting member 400, the rotating portion 200 and the second seat body 120 more compact and reducing the occupied space.

[0054] Optionally, the support portion 430, the first connection portion 410, and the second connection portion 420 are all sheet metal parts, and the support portion 430 is locked and connected to the first connection portion 410, and the support portion 430 is locked and connected to the second connection portion 420. It can be understood that in other embodiments of the present application, the support portion 430, the first connection portion 410, and the second connection portion 420 can also be aluminum profiles, steel or other metal parts, which is not limited here.

[0055] In one embodiment, see Figure 2 A guide structure 500 is provided between the first seat body 110 and the second seat body 120, and the guide structure 500 is used to guide the first seat body 110 and the second seat body 120 to be assembled along the axial direction of the bearing 300. Among them, by setting the guide structure 500, when the first seat body 110 and the second seat body 120 are assembled, it is only necessary to push the first seat body 110 and the second seat body 120 along the guide structure 500 to position and match the first seat body 110 and the second seat body 120, thereby reducing the difficulty of assembling the first seat body 110 and the second seat body 120 and ensuring the assembly accuracy of the first seat body 110 and the second seat body 120.

[0056] In one embodiment, see Figure 2 The guide structure 500 includes a guide groove 520 formed on the first base body 110 and a guide rod 510 formed on the second base body 120, and the guide rod 510 is plugged into the guide groove 520. During assembly, the end of the guide rod 510 can be inserted into the guide groove 520, and then the second base body 120 can be pushed until the guide rod 510 is completely inserted into the guide groove 520, so as to achieve accurate positioning between the second base body 120 and the first base body 110.

[0057] Specifically, the guide rod 510 is formed on the side of the side plate 122 facing the first seat body 110, and the guide groove 520 is formed on the side of the first seat body 110 facing the second seat body 120. The guide rod 510 extends along the axial direction of the rotating part 200. During assembly, the first seat body 110 and the second seat body 120 are brought closer to each other along the axial direction of the rotating part 200 so that the guide rod 510 is inserted into the guide groove 520.

[0058] Optionally, see Figure 2 The guide structure 500 includes two guide rods 510 and two guide grooves 520. The two guide rods 510 are respectively formed on the two side plates 122, and the two guide rods 510 and the two guide grooves 520 are plugged in one-to-one correspondence.

[0059] It can be understood that in other embodiments of the present application, the guide rod 510 can also be formed on the first base body 110, and the guide groove 520 can be formed on the second base body 120. In addition, the number of guide rods 510 and guide grooves 520 can also be one, three, four or more than four, which is not limited here.

[0060] In one embodiment, a first threaded hole (not shown) is formed on the first base body 110, and a second threaded hole (not shown) is formed on the second base body 120. The locking member is respectively inserted into the first threaded hole and the second threaded hole and locked. In this embodiment, the first base body 110 and the second base body 120 are positioned by the guide structure 500, and then the first base body 110 and the second base body 120 are locked by the locking member, thereby ensuring that the structure of the fixing part 100 is firm and stable.

[0061] Optionally, the number of the first threaded holes and the second threaded holes may be multiple, the first threaded holes are distributed at intervals on the first base body 110, and the second threaded holes are distributed at intervals on the second base body 120. In addition, in other embodiments of the present application, the first base body 110 and the second base body 120 may also be connected by a snap-fit ​​connection, or by an interference fit, which is not limited here.

[0062] In one embodiment, a first mounting hole (not shown) is formed on the rotating part 200, a second mounting hole (not shown) is formed on the rotor of the bearing 300, and fasteners are respectively inserted into the first mounting hole and the second mounting hole and locked. The fasteners are used to lock the rotor of the bearing 300 and the rotating part 200, thereby ensuring the installation stability of the rotating part 200 on the bearing 300, and avoiding the problem that the rotating part 200 is separated from the bearing 300 during the rotation process, resulting in unstable rotation of the rotating part 200.

[0063] In one embodiment, see Figures 1 to 3 A bearing bracket 130 is installed on the first seat body 110, and the stator of the bearing 300 is installed on the bearing bracket 130. Among them, by setting the bearing bracket 130, the support stability of the first seat body 110 to the bearing 300 can be improved, and the bearing bracket 130 can also be disassembled and repaired when the bearing bracket 130 is damaged. It can be understood that in other embodiments of the present application, a bracket for supporting the bearing 300 can also be formed on the first seat body 110, that is, the bearing 300 is directly installed on the first seat body 110, which is not limited here.

[0064] In one embodiment, see Figure 4 , Figure 6 and Figure 7A first channel 111 is formed on the first base body 110, and a cooling device 700 is provided in the first channel 111; a second channel 123 is formed on the second base body 120, and the second channel 123 is connected to the first channel 111; an air flow device 800 is provided on the first base body 110, and an air inlet of the air flow device 800 is connected to the first channel 111, and an air outlet of the air flow device 800 is connected to the second channel 123.

[0065] Since the rotating part 200 carries a radiation source and a detector for emitting X-ray beams, as well as some other electronic structures, these electronic structures will generate a lot of heat after working for a long time. When the rotating part 200 needs to be cooled, the hot air on the periphery of the second seat body 120 can be first sent into the first channel 111 through the second channel 123 by the airflow device 800; then the hot air in the first channel 111 is cooled into cold air by the cooling device 700; finally, the cold air in the first channel 111 is sent to the periphery of the second seat body 120 through the second channel 123 by the airflow device 800. In this way, the periphery of the second seat body 120, that is, the periphery of the rotating part 200 (all electronic structures are installed on the periphery of the rotating part 200) is at a suitable ambient temperature to avoid the environment overheating causing the equipment alarm.

[0066] In addition, in this embodiment, the structural space of the first base body 110 itself is used to install the cooling device 700 and accommodate a portion of the cold air, so that the hot and cold air can be isolated, which facilitates better control of heat dissipation and does not require additional space on the CT rack to install the cooling device 700.

[0067] Optionally, the airflow device 800 is installed on the outer edge of the first base body 110, and the airflow device 800 is arranged opposite to the cooling device 700, and the airflow device 800 transmits the wind cooled by the cooling device 700 to the second channel 123. It can be understood that in other embodiments of the present application, a plurality of airflow devices 800 can also be distributed on the first base body 110, wherein a part of the airflow devices 800 transmits the hot air in the second channel 123 to the first channel 111, and the other airflow devices 800 transmit the cold air in the first channel 111 to the second channel 123.

[0068] In addition, in practical applications, the entire CT rack is covered with an outer shell, which can gather hot air around the first seat body 110 so that the airflow device 800 can transport the hot air to the first channel 111 .

[0069] In one embodiment, see Figure 6The first seat body 110 has a first end face 112, and the second seat body 120 has a second end face 124. The first end face 112 and the second end face 124 are opposite and spaced apart. A convex ring 125 extends from the periphery of the second end face 124 toward the first end face 112. The first end face 112, the second end face 124 and the convex ring 125 enclose an isolation cavity 900, and the isolation cavity 900 is connected between the first channel 111 and the second channel 123. The setting of the isolation cavity 900 can achieve the isolation of the first channel 111 and the second channel 123 during the operation of the CT frame, that is, the isolation of the cold and hot air chambers, so as to facilitate the CT frame to better control the heat dissipation.

[0070] In a second aspect, the embodiment of the present application further provides a heat dissipation method for a CT rack, which is a heat dissipation method for a CT rack including the first channel 111, the second channel 123, the airflow device 800 and the cooling device 700, comprising the following steps:

[0071] S10: The hot air from the periphery is sent into the first channel 111 through the second channel 123 by the air flow device 800;

[0072] S20: Cooling the hot air in the first channel 111 into cold air by the cooling device 700;

[0073] S30 : The cold air in the first channel 111 is transported to the periphery via the second channel 123 by the air flow device 800 .

[0074] The airflow device 800 in step S10 and the airflow device 800 in step S30 may be the same device or different airflow devices 800. In addition, the airflow device 800 may be installed on the first base 110 or the second base 120.

[0075] Optionally, the airflow device 800 may be a fan or a blower.

[0076] Optionally, a cooling medium circulates in the cooling device 700, and heat is exchanged between the cooling medium and the high-temperature airflow, so that the airflow is cooled after passing through the cooling device 700, so that the high-temperature airflow becomes a low-temperature airflow, thereby improving the cooling effect. It can be understood that in other embodiments of the present application, the cooling device 700 can also be a refrigerator, such as a semiconductor refrigerator.

[0077] In a third aspect, the embodiment of the present application further provides a CT device, including the above-mentioned CT gantry. In addition, the CT device also includes a computer system, an image display system and a storage system. Among them, the transmitter and the receiver on the rotating part 200 constitute the scanning system of the CT device, and the scanning system, the image display system and the storage system are respectively connected to the computer system for communication. The scanning system transmits the scanning results to the computer system, and the computer system performs information processing according to the scanning signal and the storage signal in the storage system, and displays the calculation results through the graphic display system.

[0078] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
