Description

Technical Field

[0001] This utility model relates to the field of magnetic resonance imaging technology, and in particular to magnetic resonance imaging systems and cabin-type medical devices. Background Technology

[0002] Magnetic resonance imaging (MRI) is a technique that uses the magnetic resonance properties of atomic nuclei within a living organism to create images. Under the excitation of a radio frequency field, the atomic nuclei's spin deflects, generating magnetic resonance signals. These signals are then encoded under the influence of a gradient field, and signal processing reconstructs the magnetic resonance image. To ensure the imaging quality of an MRI system, shielding measures are necessary. Conventional methods involve constructing a separate shielded room to house the magnet system, along with an equipment room to install the corresponding cabinets, and an operating room for technicians to operate the MRI system. This results in a relatively large footprint for MRI systems. Utility Model Content

[0038] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a magnetic resonance imaging system provided in an embodiment of the present invention. Figure 2 This is a top view of a magnetic resonance imaging system provided in an embodiment of the present invention. The magnetic resonance imaging system provided in an embodiment of the present invention includes a magnetic resonance imaging device 100 and a cabinet assembly 200. The magnetic resonance imaging device 100 includes a magnet unit 110, a bed assembly 140, a first shield 120, and a second shield 130. The magnet unit 110 surrounds a detection cavity 111 and has a first end and a second end opposite to each other along its axial direction. The bed assembly 140 is coupled to the first end of the magnet unit. The first shield 120 is located at the first end to form a first shield cavity 121, and the second shield 130 is located at the second end to form a second shield cavity 131. Both the first shield cavity 121 and the second shield cavity 131 are connected to the detection cavity 111. The bed assembly 140 is housed within the first shield cavity 121. The cabinet assembly 200 is disposed adjacent to the magnet unit 110 and located outside the second shield cavity 131.

[0039] Specifically, the first shielding member 120 and the second shielding member 130 are located at the first and second ends of the magnet unit 110 in the axial direction, respectively, and are connected to the detection cavity 111 through the first shielding cavity 121 and the second shielding cavity 131, respectively, to cover the opening of the detection cavity 111, thereby achieving a good shielding effect. This eliminates the need for a dedicated shielding room to house the magnetic resonance imaging device 100, thus reducing the footprint of the magnetic resonance imaging device 100. Furthermore, the cabinet assembly 200 is positioned adjacent to the magnet unit 100 and outside the second shielding cavity 131, further reducing the footprint of the magnetic resonance imaging system and improving its adaptability. The fact that both the first shielding cavity 121 and the second shielding cavity 131 are connected to the detection cavity 111 facilitates maintenance and other operations on the magnet unit 110.

[0040] Furthermore, along the axial direction of the magnet unit 110, the projected outer contour of the magnet unit 110 falls within the projected outer contour of the first shielding member 120 and the second shielding member 130, thereby ensuring the shielding effect of the first shielding member 120 and the second shielding member 130.

[0041] See Figure 1 and Figure 2 In one embodiment, in a first direction perpendicular to the axis of the magnet unit 110, at least a portion of the projection of the cabinet assembly 200 overlaps with the projection of the second shield 130, thereby reducing the axial size of the magnetic resonance imaging system in the magnet unit 110 and thus reducing the footprint of the magnetic resonance imaging system. Furthermore, it prevents the projected outer contour of the magnet unit 110 in the first direction from falling within the projection of the cabinet assembly 200, thereby reducing the impact of the radio frequency field generated by the magnet unit 110 on the normal operation of the electronic and electrical equipment within the cabinet assembly 200, and reducing interference from the electronic and electrical equipment within the cabinet assembly 200 to the magnetic resonance radio frequency signals generated by the magnet unit 110, thus improving the reliability of the magnetic resonance imaging system.

[0042] See Figure 1 and Figure 2 In one embodiment, the outer wall of the cabinet assembly 200 on the axial side of the magnet unit 110 is flush with the outer wall of the second shield 130 on the side away from the magnet unit 110. This ensures that the magnetic resonance imaging system has a minimum size in the axial direction of the magnet unit 110, while also minimizing the distance between the cabinet assembly 200 and the magnet unit 110 in the axial direction or reducing the overlap area. This reduces the impact of the radio frequency field generated by the magnet unit 110 on the normal operation of the electronic and electrical equipment inside the cabinet assembly 200, and also reduces the interference of the electronic and electrical equipment inside the cabinet assembly 200 on the magnetic resonance radio frequency signal generated by the magnet unit 110, thereby improving the reliability of the magnetic resonance imaging system.

[0043] SeeFigure 1 and Figure 2 In one embodiment, in the first direction, the projection of the cabinet assembly 200 falls outside the outer contour of the projection of the magnet unit 110, thereby making the cabinet assembly 200 a certain distance from the magnet unit 110 in the axial direction. This reduces the impact of the radio frequency field generated by the magnet unit 110 on the normal operation of the electronic and electrical equipment in the cabinet assembly 200, and reduces the interference of the electronic and electrical equipment in the cabinet assembly 200 on the magnetic resonance radio frequency signal generated by the magnet unit 110, thereby improving the reliability of the magnetic resonance imaging system.

[0044] See Figure 1 and Figure 2 In one embodiment, at least a portion of the first shield 120 protrudes relative to the second shield 130 in a first direction, thereby providing sufficient space in the first shield cavity 121 within the first shield 120 to accommodate the bed assembly 140, the patient, and other components, ensuring the reliability of the magnetic resonance imaging system.

[0045] Furthermore, in the axial direction of the magnet unit 110, at least a portion of the projection of the cabinet assembly 200 overlaps with the projection of the first shield 120, thereby enabling the magnetic resonance imaging system to reduce its size in the first direction of the detection cavity 111, and thus reducing the footprint of the magnetic resonance imaging system.

[0046] In the first direction, at least a portion of the projection of the cabinet assembly 200 overlaps with the projection of the second shield 130, thereby reducing the size of the magnetic resonance imaging system in the axial direction of the magnet unit 110. In the axial direction of the magnet unit 110, at least a portion of the projection of the cabinet assembly 200 overlaps with the projection of the first shield 120, thereby reducing the size of the magnetic resonance imaging system in the first direction and thus accurately reducing the footprint of the magnetic resonance imaging system.

[0047] Furthermore, the first shielding member 120 extends to the outer edge of the second shielding member 130 on both sides of the first direction. The cabinet assembly 200 can be disposed on either side of the second shielding member 130 in the first direction, or the cabinet assembly 200 can be divided into two isolated parts, which are respectively disposed on both sides of the second shielding member 130 in the first direction.

[0048] See Figure 1 and Figure 2 In one embodiment, the outer wall of the cabinet assembly 200 in the first direction abuts against at least a portion of the outer wall of the second shield 130, thereby enabling the magnetic resonance imaging system to be minimized in size in the first direction.

[0049] Furthermore, in the axial direction of the magnet unit 110, the projected outer contour of the second shield 130 falls within or on the outer contour of the magnet unit 110, thereby further reducing the size of the magnetic resonance imaging system in the first direction. Specifically, in the axial direction of the magnet unit 110, the two outer walls of the second shield 130 on the side closest to the magnet unit 110 are aligned with the two outer walls of the magnet unit 110 in the first direction.

[0050] See Figure 1 and Figure 2 In one embodiment, the outer wall of the smallest region of the second shield 130 abuts against the cabinet assembly 200, thereby further increasing the overlap between the projection of the cabinet assembly 200 on the axial direction of the magnet unit 110 and the projection of the first shield 120, and further reducing the size of the magnetic resonance imaging system in the first direction.

[0051] Furthermore, the second shielding member 130 includes a first shielding segment and a second shielding segment arranged along the axial direction of the magnet unit 110. One end of the first shielding segment is connected to the magnet unit 110, and the other end of the first shielding segment is connected to the second shielding segment. The side of the second shielding segment near the cabinet assembly 200 is recessed relative to the magnet unit 110 in a first direction, and the cabinet assembly 200 abuts against the outer wall of the second shielding segment. Specifically, in the direction from the magnet unit 110 to the second shielding member 130, the size of the first shielding segment gradually decreases in the first direction.

[0052] See Figure 1 and Figure 3 , Figure 3 This is a top view of a magnetic resonance imaging system provided in another embodiment of the present invention. In one embodiment, the magnet unit 110 includes a main magnet 112 and a third shield 113. The detection cavity 111 is located in the main magnet 112. The two ends of the third shield 113 are respectively connected to the first shield 120 and the second shield 130. The third shield 113 is provided with a receiving cavity 114, and the main magnet 112 is housed in the receiving cavity 114.

[0053] Specifically, by housing the main magnet 112 within the receiving cavity 114 and connecting it to the first shield 120 and the second shield 130 at both ends of the third shield 113, the main magnet 112 is surrounded by a shielding shell formed by the first shield 120, the second shield 130, and the third shield 113, thereby improving the shielding effect and the reliability of the magnetic resonance imaging system. The magnet unit 110 may further include a gradient coil (not shown), wherein the gradient coil and the main magnet 112 can together form a hollow cavity extending along the axial direction, which forms the detection cavity 111.

[0054] Furthermore, the main magnet 112 abuts against the cavity wall of the receiving cavity 114, so that when the size of the main magnet 112 is fixed, the size of the third shield 113 in the first direction is minimized, thereby reducing the space occupied by the magnetic resonance imaging system in the first direction.

[0055] Furthermore, the first shielding component 120, the second shielding component 130, and the third shielding component 113 are integrally formed, thereby further improving the shielding effect.

[0056] See Figure 1 and Figure 2 In another embodiment, the magnet unit 110 includes a main magnet 112, the two ends of which are connected to the first shield 120 and the second shield 130 respectively, and the main magnet 112 itself provides shielding.

[0057] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the magnetic resonance imaging system is housed within a cabin 300, which has a space adapted to accommodate the magnetic resonance imaging device 100 and the cabinet assembly 200. Both the magnetic resonance imaging device 100 and the cabinet assembly 200 are housed within this space for decorative purposes. Preferably, the cabin 300 is a cuboid.

[0058] Furthermore, the cabin 300 has a first opening 310 corresponding to the first shielding member 120, so that a shielding door 122 for the person to be tested to enter and exit can be set in the area corresponding to the first opening 310 on the first shielding member 120, thereby facilitating the opening and closing of the shielding door 122 for the patient to enter and exit. The cabin 300 has a second opening 320 corresponding to the cabinet assembly 200 to facilitate maintenance services for the internal components of the cabinet assembly 200.

[0059] See Figure 1 and Figure 2 In one embodiment, the magnetic resonance imaging system further includes a display device 400 disposed on the outside of the magnetic resonance imaging device 100, and the display device 400 is used by a technician.

[0060] Specifically, the display device 400 is used by technicians to display patient information, scanning process, or test reports. The display device 400 is installed on the outer wall of the cabin 300, thus eliminating the need for an operating room to house the display device 400 and further reducing the footprint of the magnetic resonance imaging system.

[0061] In other embodiments, the display device 400 may also be disposed on the outer wall of the first shield 120 or the second shield 130.

[0062] SeeFigure 1 , Figure 2 and Figure 3 This application also provides a cabin-type medical device, including a cabin 300, a magnet unit 110, a bed assembly 140, a first shield 120, and a second shield 130. The magnet unit 110 is disposed within the cabin 300, forming a detection cavity 111 around it, and the magnet unit 110 has a first end and a second end opposite to each other. The bed assembly 140 is disposed within the cabin 300 and coupled to the first end of the magnet unit 110. The first shield 120 is disposed within the cabin 300, forming a first shield cavity 121 at its first end, and the first shield cavity 121 accommodates the bed assembly 140. The second shield 130 is disposed within the cabin 300, forming a second shield cavity 131 at its second end. Both the first shield cavity 121 and the second shield cavity 131 are connected to the detection cavity 111.

[0063] Specifically, in this application, the magnet unit 110, bed assembly 140, first shielding component 120, and second shielding component 130 are all housed within the cabin 300, i.e., integrated into one room. This facilitates the arrangement of various components within the cabin-type medical device and reduces external interference. Furthermore, the first shielding cavity 121 and the second shielding cavity 131 are both connected to the detection cavity 111, thereby facilitating maintenance and other operations on the magnet unit 110.

[0064] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the cabin-type medical device also includes a cabinet assembly 200, which is disposed inside the cabin 300, adjacent to the magnet unit 110 and located outside the second shielding cavity 131, thereby further reducing the footprint of the cabin-type medical device.

[0065] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the cabin 300 has a first opening 310, and a shielding door 122 is provided on the area corresponding to the first opening 310 on the first shielding member 120 so that the patient can enter the first shielding cavity 121 through the first opening 310.

[0066] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the compartment 300 has a second opening 320 corresponding to the rack assembly 200 to facilitate maintenance services for the internal components of the rack assembly 200.

[0067] See Figure 1 , Figure 2 and Figure 3In one embodiment, the cabin 300 is provided with a transparent observation window to facilitate observation of the specific situation inside the cabin 300.

[0068] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the outer wall of the cabin 300 is provided with a display device 400 to facilitate operation of components inside the cabin 300.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
