Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a treatment chair, magnetic resonance imaging equipment, and a treatment system. Background Technology

[0002] Traditional magnetic resonance imaging (MRI) devices in clinical applications typically require patients to lie flat during scanning. However, this scanning method has significant limitations in certain specific diagnostic and treatment scenarios. Taking dentistry as an example, on the one hand, due to equipment cost and installation space requirements, dental clinics often cannot accommodate traditional supine MRI equipment. Patients must be transferred to a dedicated MRI scanning room for examination before returning to the clinic for treatment, a process that significantly impacts diagnostic and treatment efficiency. On the other hand, even if the clinic has the necessary installation space, traditional MRI equipment cannot adapt to the pre-existing supine position of patients during dental treatment, requiring patients to repeatedly move between the chair and the scanning device, further increasing operational complexity and time costs. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a treatment chair, magnetic resonance imaging equipment and treatment system that can be adapted to the supine treatment scenario and improve the treatment efficiency in the scenario.

[0004] To achieve the above and other related objectives, this utility model provides a treatment chair that can be used in combination with an MRI machine with an inclined examination channel. The treatment chair includes:

[0005] Base;

[0006] A tilting section, mounted on the base, is configured to rotate at least along a horizontal axis;

[0007] A translation part is installed on the tilting part, and a support part is provided on the translation part. The support part is configured to support the patient in a supine sitting position, and the patient's supine sitting angle can be changed as the tilting part rotates.

[0008] The translation part is installed on the tilting part in a manner that allows it to translate along a first direction, the first direction being perpendicular to the horizontal axis, and the first direction rotating synchronously with the tilting part.

[0009] The tilting part is configured to have a first station for performing magnetic resonance scanning on a patient and a second station for performing manual diagnosis and treatment on the patient within its rotational stroke; in response to the first station, the translation path of the translation part is aligned with the examination channel of the magnetic resonance device so that the translation part can move into or out of the examination channel of the magnetic resonance device when translating along the first direction.

[0010] In an optional embodiment of the present invention, a retaining mechanism is provided between the tilting part and the base. The retaining mechanism is configured to switch between a retaining state in which the tilting part and the base are relatively fixed, and a releasing state in which the tilting part and the base can rotate relative to each other.

[0011] In an optional embodiment of the present invention, a triggering mechanism is further included for driving the holding mechanism to switch between the holding state and the releasing state. The triggering mechanism is configured to switch the holding mechanism in the holding state to the releasing state when the triggering mechanism is subjected to an external force.

[0012] In an optional embodiment of the present invention, the holding mechanism is configured to hold the tilting portion at least at the first work position and the second work position, and the angle between the first direction and the horizontal plane when the tilting portion is located at the first work position is smaller than the angle between the first direction and the horizontal plane when the tilting portion is located at the second work position.

[0013] In an optional embodiment of this utility model, the tilting part is provided with a first electromagnetic shielding layer, and the translation part is disposed above the first electromagnetic shielding layer.

[0014] In an optional embodiment of this utility model, the tilting part is provided with a driving mechanism for driving the translation part to translate along the first direction. The driving mechanism includes an electric driving element and a transmission component. The power output end of the electric driving element is connected to the translation part through the transmission component. The electric driving element is disposed below the first electromagnetic shielding layer, and the first end of the electric driving element is disposed away from the tilting part. The first end of the tilting part is the end close to the magnetic resonance imaging device when the treatment chair and the magnetic resonance imaging device are used together.

[0015] In an optional embodiment of this utility model, a following is provided between the tilting portion and the base:

[0016] A tilt drive mechanism for driving the tilting section to rotate; or

[0017] An elastic support mechanism is configured such that its elastic force can drive the tilting portion to rotate in a manner that increases the angle between the first direction and the horizontal plane.

[0018] To achieve the above and other related objectives, this utility model also provides a magnetic resonance imaging (MRI) device for use in conjunction with the aforementioned treatment chair, comprising:

[0019] A ring-shaped main magnet, the central hole of which forms an examination channel for magnetic resonance scanning;

[0020] A frame for supporting the annular main magnet is configured to hold the annular main magnet at an angle to the horizontal plane along the axis of its inspection channel, so that the inspection channel can be aligned with the translation path of the translation section when the tilting section is located at the first station.

[0021] In an optional embodiment of the present invention, the annular main magnet is supported on the frame in such a way that the angle between the axis of the inspection channel and the horizontal plane can be adjusted.

[0022] In an optional embodiment of this utility model, it further includes:

[0023] The second electromagnetic shielding layer is electromagnetically connected to the metal shielding layer of the annular main magnet, and the second electromagnetic shielding layer seals one end of the inspection channel.

[0024] The third electromagnetic shielding layer is electromagnetically connected to the metal shielding layer of the annular main magnet. The third electromagnetic shielding layer is movably disposed relative to the annular main magnet so that the third electromagnetic shielding layer can switch between the first state and the second state.

[0025] In response to the first state, the third electromagnetic shielding layer can be electromagnetically connected to the first electromagnetic shielding layer provided on the treatment chair, and together with the first electromagnetic shielding layer, form a patient reception compartment that is connected to the other end of the examination channel.

[0026] In response to the second state, the third electromagnetic shielding layer can be separated from the first electromagnetic shielding layer on the treatment chair to open the patient reception compartment.

[0027] To achieve the above and other related objectives, this utility model also provides a diagnostic and treatment system, comprising:

[0028] The aforementioned treatment chair; and

[0029] The aforementioned magnetic resonance device;

[0030] The examination chair and the magnetic resonance imaging (MRI) device are assembled such that when the tilting part is located in the first position, the translation path of the translation part is aligned with the examination channel of the MRI device.

[0031] The technical advantages of this invention are as follows: By tilting the examination channel of the MRI equipment and combining it with an adjustable reclining angle and a diagonally movable treatment chair, patients can continuously complete treatment and scanning on the same chair without repeated movement, thus significantly simplifying the treatment process and improving efficiency. The tilted examination channel saves horizontal installation space and reduces the height requirements of the examination room. The adjustable angle of the treatment chair provides a large reclining angle for medical staff during treatment and a smaller reclining angle for the MRI equipment during scanning. Combined with diagonal movement, patients can complete the entire process from treatment to scanning without needing to move. This fundamentally solves the multiple limitations of traditional equipment in terms of space adaptation, body positioning, and process connection, significantly improving treatment efficiency and user experience.

[0038] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] When MRI equipment is used in some specialized treatments, patients need to be transferred multiple times between the scanning room and the dental clinic. For example, in dentistry, patients must first move to the MRI scanning room for imaging and then return to the dental clinic for treatment. This process is not only cumbersome but also significantly reduces overall treatment efficiency due to spatial transitions and time delays. Another solution is to deploy the MRI equipment directly within the dental clinic; however, this approach faces several challenges: First, the MRI equipment generates a strong magnetic field during operation, requiring specialized shielding structures (such as shielding walls) to prevent magnetic interference. This significantly increases construction and renovation costs, and many existing dental clinics lack sufficient space for installation. Second… Traditional MRI scanners primarily use a supine position for scanning, which is unsuitable for the seated position commonly used in dental treatment. This means that even with the equipment present, patients still need to move between the chair and the scanner, failing to fundamentally simplify the process. Furthermore, the large lateral size of MRI scanners means most clinics cannot allocate dedicated installation space for them. Some solutions allow for upright MRI scanners, which improve posture adaptability and match the positioning requirements of dental treatment. However, these also have stringent installation requirements, such as sufficient ceiling height. Conventional dental clinics are often cramped and have limited ceiling height, making it difficult to accommodate such equipment and thus limiting its practical application. The fundamental reasons for the limited widespread use of MRI scanners in dental and other specialized treatment environments can be attributed to the mismatch between the equipment's physical form and the patient's position, the space and cost pressures associated with shielding requirements, and the inherent limitations of most specialized clinics in terms of space, structure, and ceiling height. These factors collectively prevent the integration and efficiency optimization of the treatment process and the MRI scanning process.

[0041] Therefore, this utility model provides a diagnostic and treatment system, including a treatment chair and an MRI machine that can be used in combination. The examination channel of the MRI machine can be tilted. Compared with a supine MRI machine, the tilted MRI machine saves more lateral space, and the angle of the examination channel is closer to the backrest angle of the treatment chair, making it easier to adapt to the patient's position during dental treatment. Compared with a vertical MRI machine, the tilted MRI machine saves more longitudinal space, reducing the height requirement of the treatment room. The treatment chair can adjust the reclining angle to meet the needs of large reclining angles during diagnosis and treatment (the angle between the backrest and the horizontal plane is relatively large, which is convenient for medical staff to perform examinations or treatments), as well as the needs of small reclining angles during MRI scanning (in order to reduce the height requirement, the angle between the axis of the MRI machine and the horizontal plane should not be too large). In addition, the treatment chair can drive the patient to translate along the axial direction of the examination channel of the MRI machine, thereby allowing the patient to move into or out of the examination channel. This utility model enables patients to continuously complete a series of treatment processes such as diagnosis, treatment, and scanning imaging on the treatment chair, simplifying the treatment process and improving treatment efficiency.

[0042] Please see Figure 1-6 As shown, the technical solution of this utility model will be described in detail below with reference to specific embodiments:

[0043] Please see Figure 3-6 As shown, an embodiment of this utility model provides a diagnostic and treatment system, including... Figure 1 The examination chair 100 shown, and Figure 2 The magnetic resonance imaging (MRI) device 200 is shown. It should be noted that the examination chair 100 and the MRI system in this invention can be used in combination, but this does not mean they must be used together. For example, the examination chair 100 can also be used with other types of MRI devices, such as horizontally or vertically placed MRI devices. Similarly, the MRI device 200 of this invention can also be used with other types of examination chairs or tables, and the movement of these chairs or tables is not limited to those specified in this invention. When the examination chair 100 and the MRI device 200 provided by this invention are used in combination, it not only solves the problem of integrating specialized diagnosis and treatment with MRI scanning, but also allows for flexible adjustment of the alignment angle between the MRI device 200 and the examination chair 100 to adapt to different installation environments or patient positions required for different treatment procedures. Therefore, using them in combination is a more preferred solution.

[0044] Please see Figure 1As shown, the medical chair 100 provided in the embodiment of this utility model includes a base 10, a tilting part 20, and a translating part 30; the base 10 serves as the basic support for the medical chair 100 and can be installed on the ground or a platform; the tilting part 20 is installed on the base 10, and the tilting part 20 is configured to be able to rotate at least along a horizontal axis, the horizontal axis being in... Figure 1-6 The axis is perpendicular to the plane of the paper; in a specific embodiment, the tilting part 20 can rotate only along the horizontal axis, or it can be accompanied by other movements simultaneously. For example, the tilting part 20 can also move as a whole along the horizontal, vertical, or inclined direction while rotating; the translation part 30 is installed on the tilting part 20, and the translation part 30 is provided with a support part 31. The support part 31 is configured to support the patient 300 in a supine posture, and the supine angle of the patient 300 can be changed with the rotation of the tilting part 20; the translation part 30 is installed on the tilting part 20 in a manner that allows translation along a first direction X, the first direction X being perpendicular to the horizontal axis, and the first direction X rotating synchronously with the tilting part 20; Figure 4-6 As shown, the tilting part 20 is configured such that within its rotational stroke there exists a first station that aligns the translation path of the translation part 30 with the inspection channel of the magnetic resonance device 200.

[0045] Please see Figure 2 As shown, the magnetic resonance imaging (MRI) device 200 provided in this embodiment includes a ring-shaped main magnet 60 and a frame 70. The central hole of the ring-shaped main magnet 60 forms an examination channel 61 for MRI scanning. The frame 70 supports the ring-shaped main magnet 60 and is configured to hold the ring-shaped main magnet 60 at an angle between the axis of its examination channel 61 and the horizontal plane, so that the examination channel 61 is adapted to the tilt angle of the examination chair 100. It should be noted that the tilt angle of the examination chair 100 is adjustable. The adaptation of the examination channel 61 to the tilt angle of the examination chair 100 in this embodiment means that the examination channel 61 is adapted to at least one of the tilt angles of the examination chair 100.

[0046] This invention, by tilting the examination channel 61 of the MRI device 200 and combining it with an adjustable reclining angle and a diagonally movable treatment chair 100, allows the patient 300 to continuously complete treatment and scanning on the same treatment chair 100 without repeated movement, thus significantly simplifying the treatment process and improving efficiency. The tilted examination channel 61 saves lateral installation space and reduces the height requirements of the examination room. The adjustable angle of the treatment chair 100 provides a large reclining angle for convenient operation by medical staff during treatment and a smaller reclining angle for scanning to fit the MRI device 200. Combined with diagonal movement, the patient 300 can complete the entire process from treatment to scanning without relocation. This fundamentally solves the multiple limitations of traditional equipment in terms of space adaptation, body positioning, and process connection, significantly improving treatment efficiency and user experience.

[0047] Please see Figure 1 , 3 As shown in Figure 6, in an optional embodiment of this utility model, a retaining mechanism 40 is provided between the tilting part 20 and the base 10. The retaining mechanism 40 is configured to switch between a retaining state in which the tilting part 20 and the base 10 are relatively fixed, and a releasing state in which the tilting part 20 and the base 10 can rotate relative to each other. The above-mentioned function of the retaining mechanism 40 can be implemented in various ways. For example, in some embodiments, two gears coaxial with the horizontal axis can be respectively provided on the base 10 and the tilting part 20. The two gears are circumferentially fixed to the base 10 and the tilting part 20, respectively, and one of the gears can slide axially. When the two gears mesh axially, the tilting part 20 and the base 10 remain fixed; when the two gears separate axially, the tilting part 20 can rotate freely relative to the base 10. In other embodiments, the gears can also be replaced by a ratchet pawl mechanism or a pin mechanism, etc. Any mechanism that can achieve circumferential locking and releasing should be applicable to this utility model. This invention achieves reliable locking and flexible release between the tilting part 20 and the base 10 through the retaining mechanism 40, ensuring the stability and accuracy of the treatment chair 100 in both treatment and scanning states. When the mechanism is in the retaining state, it can firmly lock the tilting angle, providing a stable support platform for dental treatment and MRI scanning, ensuring the safety of surgery or operation. When it is necessary to switch between the treatment position and the scanning position, the retaining mechanism 40 switches to the release state, allowing the tilting part 20 to rotate flexibly to the preset scanning angle or treatment angle, thereby achieving rapid and accurate switching of the patient's position while ensuring stability.

[0048] Please see Figure 1 , 3As shown in Figure 6, in an optional embodiment of this utility model, a trigger mechanism 41 is further included for driving the holding mechanism 40 to switch between the holding state and the releasing state. The trigger mechanism 41 is configured to switch the holding mechanism 40 from the holding state to the releasing state when the trigger mechanism 41 is subjected to an external force. In a specific embodiment, the trigger mechanism 41 can be automatic or manual. For example, in a manual embodiment, the trigger mechanism 41 can include interactive units such as pedals, levers, or buttons. These interactive units can be connected to the holding mechanism 40 via transmission methods such as pull cables, linkages, or hydraulic pressure. When the interactive unit is subjected to an external force, the holding mechanism 40 can be driven to switch to the releasing state through these transmission methods. Similarly, in an automatic embodiment, interactive units such as pedals, levers, or buttons can also be provided, along with driving elements such as motors or electric actuators for driving the holding mechanism 40 to switch states. When the interactive unit is operated by an operator, the driving element can be controlled to move, thereby realizing the state switching of the holding mechanism 40. The triggering device 41 of this invention can realize the operation logic of normal holding and trigger release, which improves the safety and convenience of the treatment chair 100. Specifically, when the triggering device 41 is not operated, the holding mechanism 40 automatically locks, ensuring the absolute stability of the treatment chair 100 at various angles and providing reliable support for delicate dental operations and magnetic resonance scanning. When it is necessary to change the position, medical staff only need to operate the triggering mechanism 41 to quickly release the lock, so that the tilting part 20 can be flexibly adjusted to the required angle. This invention simultaneously ensures the stability of the treatment chair 100 and the flexibility of position switching, making the treatment process safer and more efficient.

[0049] Please see Figure 3 , 4 As shown, in an optional embodiment of this utility model, the holding mechanism 40 is configured to hold the tilting part 20 at least in the first position and at least in the second position within the rotational stroke of the tilting part 20; the angle between the first direction X and the horizontal plane when the tilting part 20 is in the first position is smaller than the angle between the first direction X and the horizontal plane when the tilting part 20 is in the second position. This holding mechanism 40 perfectly matches the different positioning requirements in the diagnostic and treatment process by precisely locking the tilting part 20 in the first scanning position and the second treatment position; in the second position, the larger tilt angle provides medical staff with an ideal treatment posture, facilitating operation; while in the first position, the smaller tilt angle precisely aligns with the examination channel 61 of the magnetic resonance imaging device 200, ensuring smooth scanning; this multi-position locking mechanism allows the treatment chair 100 to quickly and accurately switch between the two core scenarios of treatment and scanning, ensuring the optimal working state of each stage and achieving seamless integration of the diagnostic and treatment process.

[0050] Please see Figure 5 , 6 As shown, in an optional embodiment of this utility model, the tilting part 20 is provided with a first electromagnetic shielding layer 21, and the translation part 30 is disposed above the first electromagnetic shielding layer 21. In some embodiments, when the top plate above the tilting part 20 for supporting the translation part 30 is made of metal, the top plate can serve as the first electromagnetic shielding layer 21. In other embodiments, a special shielding material can also be used as the first electromagnetic shielding layer 21. The magnetic resonance device 200 includes a second electromagnetic shielding layer 80 and a third electromagnetic shielding layer 90. The second electromagnetic shielding layer 80 is electromagnetically connected to the inherent metal shielding layer 62 of the annular main magnet 60. The second electromagnetic shielding layer 80 closes one end of the inspection channel 61 (i.e., the higher end of the inspection channel 61). The third electromagnetic shielding layer 90 is electromagnetically connected to the metal shielding layer 62 of the annular main magnet 60. 2. Electromagnetic conduction: The third electromagnetic shielding layer 90 is movably disposed relative to the annular main magnet 60, so that the third electromagnetic shielding layer 90 can switch between a first state and a second state; in a specific embodiment, the third electromagnetic shielding layer 90 can be hinged to the annular main magnet 60, or slidably connected to the annular main magnet 60 along the radial direction of the annular main magnet 60; in response to the first state, the third electromagnetic shielding layer 90 can be electromagnetically connected to the first electromagnetic shielding layer 21 disposed on the treatment chair 100, and together with the first electromagnetic shielding layer 21, form a patient reception compartment communicating with the other end of the examination channel 61 (i.e., the lower end of the examination channel 61); in response to the second state, the third electromagnetic shielding layer 90 can be separated from the first electromagnetic shielding layer 21 on the treatment chair 100 to open the patient reception compartment. This invention, by setting interconnected shielding layers on each component, together constructs a closed patient containment chamber when the treatment chair 100 and the magnetic resonance imaging device 200 are connected. This allows the system to form a complete electromagnetic shielding environment without relying on professional shielding modifications to the clinic building structure, thereby significantly reducing the requirements for installation space and construction costs. This enables the magnetic resonance imaging device 200 to be flexibly deployed in conventional dental clinics.

[0051] Please see Figure 1 , 3As shown in Figure 6, in an optional embodiment of this invention, the tilting portion 20 is provided with a driving mechanism for driving the translation portion 30 to translate along the first direction X. The driving mechanism includes an electric driving element 22 and a transmission component 23. The power output end of the electric driving element 22 is connected to the translation portion 30 via the transmission component 23. The electric driving element 22 is disposed below the first electromagnetic shielding layer 21, and the first end of the electric driving element 22 is disposed away from the tilting portion 20. The first end of the tilting portion 20 is the end closer to the magnetic resonance imaging device 200 when the treatment chair 100 and the magnetic resonance imaging device 200 are used together. By arranging the electric driving element 22 at the end of the tilting portion 20 away from the magnetic resonance imaging device 200 and using the first electromagnetic shielding layer 21 to isolate it from the scanning area, this invention minimizes the potential interference of the main magnetic field on the electronic components, and achieves safe and reliable linkage between the treatment chair 100 and the magnetic resonance imaging device 200 while ensuring imaging quality. In a specific embodiment, the electric driving element 22 may be, for example, a motor, and the transmission component 23 may be, for example, a synchronous belt pulley mechanism.

[0052] Please see Figure 1 , 3 As shown in Figure 6, in an optional embodiment of this utility model, an elastic support mechanism 50 is provided between the tilting part 20 and the base 10. The elastic support mechanism 50 is configured such that its elastic force can drive the tilting part 20 to rotate in a way that increases the angle between the first direction X and the horizontal plane. This embodiment uses a non-powered method to adjust the tilt angle of the tilting part 20, which simplifies the equipment structure and reduces costs, while also improving the tilt angle adjustment response speed and accuracy. Specifically, the elastic force of the elastic support mechanism 50 can offset the weight of the treatment chair 100 and the patient 300 to a certain extent, preventing the tilting part 20 from tipping over without restraint. At the same time, a slight external force can be applied to the tilting part 20 to change its angle. Combined with the holding and releasing process of the holding mechanism 40, the tilting part 20 can be switched between different angles. In a specific embodiment, the elastic support mechanism 50 may be, for example, a gas strut, a spring, or other elastic support component; it should be understood that in some other alternative embodiments, an active drive element may also be provided as a tilt drive mechanism to adjust the angle of the tilt part 20 in order to achieve the most basic function of tilt part 20 angle adjustment. These active drive elements may be, for example, a motor, a hydraulic cylinder, etc.

[0053] Please see Figure 2-6As shown, in an optional embodiment of this invention, the annular main magnet 60 is supported on the frame 70 in a manner that allows adjustment of the angle between the axis of the examination channel 61 and the horizontal plane. This embodiment greatly improves the adaptability of the diagnostic and treatment system to different examination room space conditions by making the tilt angle of the examination channel 61 of the magnetic resonance equipment 200 adjustable. For examination rooms with limited ceiling height, a smaller tilt angle (a gentler channel) can be used to reduce the overall height of the equipment; for examination rooms with limited lateral space, a larger tilt angle (a steeper channel) can be used to save floor space. This flexibility allows the same system to be flexibly adapted to various building layouts without the need for expensive site modifications to accommodate the equipment, thereby significantly reducing the spatial threshold and implementation cost of deploying the magnetic resonance equipment 200 in existing dental clinics. In addition, in a further embodiment, the magnetic resonance equipment 200 or the treatment chair 100 can be configured as a vertically adjustable structure so that the patient 300 can enter the examination channel 61 at different reclining angles, thereby adapting to the positional requirements of different treatment scenarios.

[0054] In summary, this invention, by tilting the examination channel 61 of the MRI device 200 and combining it with an adjustable reclining angle and a tiltable treatment chair 100, allows the patient 300 to continuously complete treatment and scanning on the same treatment chair 100 without repeated movement, thus significantly simplifying the treatment process and improving efficiency. The tilted examination channel 61 saves lateral installation space and reduces the height requirements of the examination room. The adjustable angle function of the treatment chair 100 provides a large reclining angle for convenient operation by medical staff during treatment and can be switched to a smaller reclining angle during scanning to adapt to the MRI equipment. The device, equipped with a 200-degree tilt mechanism, allows the patient (300) to complete the entire procedure from treatment to scanning without needing to be moved. This fundamentally solves the multiple limitations of traditional equipment in terms of spatial adaptation, patient positioning, and workflow integration, significantly improving diagnostic and treatment efficiency and user experience. The device utilizes a retaining mechanism (40) to reliably lock and flexibly release the tilting section (20) and the base (10), ensuring the stability and accuracy of the treatment chair (100) in both treatment and scanning states. When the mechanism is in the retaining state, it firmly locks the tilt angle, providing a stable support platform for dental treatment and MRI scanning, ensuring the safety of the procedure. When needed... When switching between the treatment station and the scanning station, the mechanism 40 is kept in the released state, allowing the tilting part 20 to rotate flexibly to the preset scanning angle or treatment angle. This achieves rapid and precise switching of the patient's position while maintaining stability. This invention, by setting interconnected shielding layers on each component, jointly constructs a closed patient containment chamber when the treatment chair 100 and the MRI machine 200 are connected. This allows the system to form a complete electromagnetic shielding environment, eliminating the need for professional shielding modifications to the examination room structure. This significantly reduces the requirements for installation space and construction costs, making the magnetic resonance imaging (MRI) system more effective. The MRI device 200 can be flexibly deployed in conventional dental clinics. By making the tilt angle of the examination channel 61 of the MRI device 200 adjustable, this invention greatly improves the adaptability of the treatment system to different clinic space conditions. For clinics with limited ceiling height, a smaller tilt angle can be used to reduce the overall height of the device. For clinics with limited lateral space, a larger tilt angle can be used to save floor space. This flexibility allows the same system to be flexibly adapted to various building layouts without the need for expensive site modifications to accommodate the device, thereby significantly reducing the space threshold and implementation cost of deploying the MRI device 200 in existing dental clinics.
