[0058] For a clearer understanding of the technical features, objects and effects of the present disclosure, specific embodiments of the present disclosure will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals indicate the same parts.

[0059] In this document, "illustrative" means "serving as an example, instance, or illustration," and should not necessarily be construed as preferred or advantageous over other examples. Any example described herein as "illustrative" is intended to be merely that, and not to be construed as a more preferred or advantageous example than other examples.

[0060] For the sake of brevity, the drawings of the various aspects will not be described in detail if it can obscure salient aspects of the various aspects. In addition, in some instances, details of certain well-known structures of magnetic resonance imaging apparatuses have been omitted in order to avoid obscuring the underlying principles of the various aspects.

[0061] In this document, "one" does not necessarily mean "only one", but can also mean "more than one". In this document, "first", "second", and the like are used only to distinguish one entity from another, and do not necessarily indicate the importance of the entities and the order of existence, and the like.

[0062] In the related art, a magnetic resonance imaging apparatus includes an apparatus main body including a body coil for emitting a radio frequency signal and a gradient coil provided outside the body coil, the body coil being a cylindrical structure, and a bed body capable of ascending and descending relative to the apparatus main body and horizontally moving, thereby delivering a subject to be detected into the body coil.

[0063] In the related art, the body coil is detached by using a dedicated support, the dedicated support being a bar-shaped structure, and the body coil is provided with a dedicated support fixing member at both ends thereof, when the body coil is to be detached, the two dedicated supports are respectively installed on the two dedicated support fixing members at both ends of the body coil, then the fastener on the body coil is removed, so that the body coil is loosened from the magnetic resonance imaging apparatus, then two persons hold the two dedicated supports respectively, and lift the body coil onto the strip-shaped guide rail on the surface of the gradient coil, and then move the body coil out of the magnetic resonance imaging apparatus along the strip-shaped guide rail. In addition, in order to facilitate the support of the detached body coil, a guide rail frame is also specially provided, which can be placed on the bed body, and the body coil can be placed on the guide rail frame after being lifted out.

[0064] However, since the body coil is usually made of glass fiber reinforced plastic, it has a large volume and weight, and is difficult to operate by manpower to lift the body coil, and installation risks exist. Moreover, a special bracket fixing member needs to be arranged on the body coil, and a strip-shaped guide rail needs to be arranged on the gradient coil, resulting in a complex structure of the body coil and the gradient coil.

[0065] To solve at least one of the above problems, the body coil dismounting tool, the transport box cooperating with the body coil dismounting tool, and the body coil dismounting tool set comprising the body coil dismounting tool and the transport box are provided, wherein the body coil dismounting tool has a body capable of penetrating the body coil and at least one support portion arranged on the body, the at least one support portion being capable of supporting the body coil inside the body coil, when the body coil is loosened from the magnetic resonance imaging device, the body coil can be supported on the support portion and can move with the support portion, so as to be moved out of the magnetic resonance imaging device, without manual carrying of the body coil, convenient dismounting and time and labor saving.

[0066] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Figure 2 The present embodiment provides a body coil dismounting tool which can be used to dismount the body coil from the magnetic resonance imaging device or install the body coil into the magnetic resonance imaging device. For the convenience of description, only the use of the body coil dismounting tool in the process of dismounting the body coil will be described below, and the use of the body coil dismounting tool in the process of installing the body coil can be used in a method opposite to the sequence of the process of dismounting the body coil, which will not be described here.

[0067] In the present embodiment, the body coil dismounting tool comprises a moving assembly 100 and a bracket assembly 200, the moving assembly 100 can be used to support the body coil 400, and the bracket assembly 200 can be used to support the moving assembly 100.

[0068] The moving assembly 100 can comprise a body 110 extending along a first direction and at least one support portion 120 arranged on the body 110. The body 110 can be a rod-shaped structure or a columnar structure extending along the first direction, which can penetrate the body coil 400, and the first direction can coincide with or be parallel to the axial direction of the body coil 400.

[0069] At least one support portion 120 can be connected to the body 110, and each support portion 120 can be in contact with the inner surface of the body coil 400, so that the support portion 120 functions to support the inner surface of the body coil 400. The structure of the support portion 120 can be various, for example, the support portion 120 can be a ring structure which is sleeved on the body 100, and the outer surface of the support portion 120 can be attached to the inner surface of the body coil 400, so as to function to support the body coil 400. For another example, the support portion 120 can be a fan structure which is arranged on the body 100, and the arc surface of the fan structure can be in contact with the inner surface of the body coil 400, so as to function to support the body coil 400.

[0070] The support assembly 200 can be connected to the body 110 to support the moving assembly 100. The structure of the support assembly 200 can also be various, for example, the support assembly 200 can have a base and two support arms which are connected to the base, and each support arm can be connected to one end of the body 110, so as to function to support the body 110. For another example, the support assembly 200 can include a support base and two hangers which are connected to the top end of the support base, and each hanger can be connected to one end of the body 110, so as to lift the body 110.

[0071] At least one support portion 120 of the moving assembly 100 can move as a whole relative to the support assembly 200 along the first direction, so as to drive the body coil 400 to move along the first direction.

[0073] Please refer to Figures 3 to 6When the body coil is disassembled, the body 110 can be first passed through the body coil 400, and the body 110 is supported on the support assembly 200, then the supporting portion 120 is supported on the inner surface of the body coil 400, then the fasteners of the body coil 400 are removed, so that the body coil 400 is loosened from the magnetic resonance imaging equipment, and due to the supporting action of the supporting portion 120, the position of the loosened body coil 400 relative to the magnetic resonance imaging equipment is basically unchanged, then the body coil or the supporting portion 120 can be pushed to move the body coil 400 together with the supporting portion 120 in the first direction, so as to move the body coil 400 out of the magnetic resonance imaging equipment, and the process does not need to lift or carry the body coil 400 manually, is quick and convenient to disassemble and assemble, saves time and effort, and has no safety hazard. In addition, due to the quick disassembly and assembly, the time of the operator exposed to the magnetic field can be reduced, and the safety of the disassembly and assembly process is improved. Compared with the disassembly manner in the related art, the body coil disassembly and assembly tool provided in the embodiment has high independence and universality, and does not need to be provided with a special support fixing piece on the body coil and a strip-shaped guide rail on the gradient coil, so that the structure of the body coil and the gradient coil is simplified.

[0074] Figure 7 For Figure 2 is a partial enlarged view. Please refer to Figure 7 In some embodiments, each of the at least one supporting portion 120 comprises at least one supporting rod 121, a first end of each supporting rod 121 is connected to the body 110, and a second end of each supporting rod 121 is used to contact the inner surface of the body coil 120. By using the supporting rod 121 to support the body coil 120, the structure of the supporting portion 120 can be simplified, and it is easy to process and manufacture.

[0075] It can be understood that if each supporting portion 120 only comprises one supporting rod 121, the body coil 400 can be movably supported on the second end of the supporting rod 121, that is, there is one supporting point between the body coil 400 and each supporting portion 120, the body coil 400 and the supporting rod 121 are movably connected, and the body coil 400 can shake relative to the supporting rod 121 under the action of an external force. If each supporting portion 120 comprises a plurality of supporting rods 121, the second ends of the plurality of supporting rods 121 can be spaced apart along the circumferential direction of the body coil 120, so as to fixedly support the body coil 400 on the supporting portion 120. In addition, when the body coil 400 and the supporting rod 121 are movably connected, the body coil 400 can be moved out of the magnetic resonance imaging equipment by pushing the supporting rod 121, and when the body coil 400 and the supporting rod 121 are fixedly connected, the body coil 400 can be directly pushed to move out of the magnetic resonance imaging equipment.

[0076] Optionally, each support part 120 can include three support rods 121, which can be equidistantly arranged along the circumferential direction of the body coil 400, so that each support part 120 can have three support points with the inner surface of the body coil 400, so that the support stability of the support part 120 is higher.

[0077] Further optionally, the second end of each of the at least one support rod 121 can be provided with an anti-skid part 125 for increasing the friction with the inner surface of the body coil 400. The structure of the anti-skid part 125 can be various, for example, the anti-skid part 125 can be made of rubber or other anti-skid materials. Alternatively, the surface of the anti-skid part 125 can be provided with a texture to increase the friction with the body coil 400.

[0078] In some embodiments, the first end of each of the at least one support rod 121 is hinged to the body 110, and each of the at least one support rod 121 forms a first angle with the body 110, and the first angle can be adjusted. That is, the first angle between each support rod 121 and the body 110 can be adjusted as needed, and the support rod 121 can also be fixed at the adjusted first angle.

[0079] It can be understood that in each support part 120, the second ends of the plurality of support rods 121 can be connected into a circle, and by adjusting the first angle between the support rod 121 and the body 110, the diameter of the circle can be adjusted accordingly, so that the support part 120 can adapt to body coils 400 of different sizes, improving the versatility of the body coil disassembling tool.

[0080] Figure 8 For Figure 1 the structure diagram of the moving assembly in the storage state. Please refer to Figure 7 and Figure 8 , the body coil disassembling tool can have a storage state and a working state, when in the working state, the second end of the support rod 121 can be supported on the inner surface of the body coil 400, and the body coil disassembling tool can be used to disassemble the body coil. When the body coil disassembling tool is in the storage state, the first angle between the support rod 121 and the body 110 can be adjusted, so that the support rod 121 can be as close as possible to the body 110 to reduce the volume of the body coil disassembling tool after storage.

[0081] Continue to refer to Figure 7 In some embodiments, each of the at least one support part 120 further includes an adjusting member 600 for adjusting the first angle, the adjusting member 600 is arranged on the body 110, and the adjusting member 600 includes a sliding sleeve 123, a locking member 122, and at least one sub-connection rod 124.

[0082] The sliding sleeve 123 is sleeved on the body 110, and the sliding sleeve 123 can be a cylindrical structure and can freely slide on the body 110.

[0083] The sub-connecting rods 124 are rod-shaped structures, the first ends of each of the sub-connecting rods 124 are hingedly connected to the sliding sleeve 123, and the second ends thereof are hingedly connected to one of the support rods 121. Optionally, the first ends of the sub-connecting rods 124 are hingedly connected to the outer surface of the sliding sleeve 123, and the second ends thereof are hingedly connected to the middle positions of the support rods 121.

[0084] The locking member 122 is used to lock the distance between the sliding sleeve 123 and the first end of the support rod 121. It can be understood that the sliding sleeve 123 can be located between the first end of the support rod 121 and the locking member 122, and the sliding sleeve 123 can abut against the locking member 122. By adjusting the position of the locking member 122 connected to the body 110, the distance between the sliding sleeve 123 and the first end of the support rod 121 can be adjusted, so as to adjust the first angle between the support rod 121 and the body 110 and fix the support rod 121 at the first angle. Moreover, by adjusting the locking member 122, the first angles between the plurality of support rods 121 and the body 110 can be simultaneously adjusted, and the adjustment is more convenient.

[0085] In some embodiments, the locking member 122 can have an internal thread, and the body 110 can be provided with an external thread. The locking member 122 is screwed to the body 110. By rotating the locking member 122, the first angle between the support rod 121 and the body 110 can be adjusted, and the support rod 121 can be fixedly connected at the first angle. The structure is simple and easy to realize.

[0086] In the above various embodiments, the first angle between the support rod 121 and the body 110 is adjustable. In other embodiments, the first end of each of the at least one support rod 121 is fixedly connected to the body 110, and each of the at least one support rod 121 forms a second angle with the body 110. The second angle between each of the support rods 121 and the body 110 is a fixed angle and is not adjustable. This structure can also realize the supporting effect on the body coil 400. Taking the example that each of the support portions 120 includes a plurality of support rods 121, when the inner diameter size of the body coil 400 to be disassembled is the same as the diameter of the circle in which the second ends of the plurality of support rods 121 are located, the second ends of each of the support rods 121 can be in contact with the inner surface of the body coil 400, so that the body coil 400 and the support portion 120 can be relatively fixed. If the inner diameter size of the body coil 400 is greater than the diameter of the circle, the second end of at least one of the plurality of support rods 121 can be in contact with the inner surface of the body coil 400, so that the body coil 400 can be movably supported on the support portion 120.

[0087] In some embodiments, the moving assembly 100 can include two support portions 120, which are oppositely arranged on the body 110 along the first direction. The two support portions 120 can be spaced apart along the first direction and can be symmetrically arranged about a plane perpendicular to the first direction, so that the body coil 400 can be supported from both ends, and the support effect is better.

[0088] Please refer to Figure 2 , as an optional implementation of the body 110, the body 110 can include a first telescopic rod 111a, a second telescopic rod 111b, and an intermediate rod 112, which can be connected between the first telescopic rod 111a and the second telescopic rod 111b. Wherein the first telescopic rod 111a and the second telescopic rod 111b respectively extend along the first direction and can move along the first direction. The length of the first telescopic rod 111a and the second telescopic rod 111b along the first direction can be changed by telescopic movement.

[0089] Optionally, one support portion 120 can be arranged between the first telescopic rod 111a and the intermediate rod 112, and one support portion 120 can be arranged between the second telescopic rod 111b and the intermediate rod 112, thereby playing a role in stabilizing the support of the body coil 400.

[0090] As shown in Figure 3 , when the body coil needs to be disassembled, the body 110 can be first passed through the body coil 400, and the body 110 is supported on the support assembly 200, and then the support portion 120 is supported on the inner surface of the body coil 400. At this time, the state of the first telescopic rod 111a and the second telescopic rod 111b can refer to Figure 1 , that is, the first telescopic rod 111a can be in a contracted state with a shorter length, and the second telescopic rod 111b can be in an elongated state with a longer length, then remove the fastener of the body coil 400, so that the body coil 400 is loosened from the magnetic resonance imaging device, and due to the supporting effect of the support portion 120, the position of the body coil 400 after being loosened relative to the magnetic resonance imaging device is basically unchanged, refer to Figures 4 to 6 , push the body coil 400, the first telescopic rod 111a is elongated, and at the same time the second telescopic rod 111b is shortened, so that the body coil 400 together with the support portion 120 moves along the first direction until the body coil 400 is moved out of the magnetic resonance imaging device.

[0091] Please refer to Figure 8 , when the first telescopic rod 111a and the second telescopic rod 111b are in the contracted state, the moving assembly 100 can be in the storage state. Therefore, the first telescopic rod 111a and the second telescopic rod 111b not only can realize the movement of the body coil 400 along the first direction, but also can reduce the storage size of the moving assembly 100, facilitating storage and transportation.

[0092] Of course, in Figures 3 to 6 In the embodiment shown, the length of the first telescopic rod 111a is increased and the length of the second telescopic rod 111b is decreased during the disassembly of the body coil 400, but in other embodiments, the positions of the first telescopic rod 111a and the second telescopic rod 111b can be reversed, i.e., the length of the first telescopic rod 111a is decreased and the length of the second telescopic rod 111b is increased during the disassembly of the body coil 400, which is not specifically limited herein.

[0093] As an optional way for the first telescopic rod 111a and the second telescopic rod 111b to achieve telescopic movement, the first telescopic rod 111a and the second telescopic rod 111b each include a plurality of first sub-rods 1111 that are sequentially sleeved from the outside to the inside along the rod diameter direction, and each first sub-rod 1111 among the plurality of first sub-rods 1111 can move relative to the first sub-rod 1111 adjacent thereto in a first direction.

[0094] Optionally, the outer surface of the first sub-rod 1111 located inside among the two adjacent first sub-rods 1111 can be provided with at least one first strip-shaped protrusion extending in the first direction, and the inner surface of the first sub-rod 1111 located outside can be provided with at least one first strip-shaped groove extending in the first direction, each first strip-shaped protrusion and each first strip-shaped groove are one-to-one matched and can slide relative to each other, thereby achieving the relative movement of the two adjacent first sub-rods 1111 in the first direction.
