[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following will clearly and completely describe the technical solutions of the embodiments of this application in conjunction with the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application.

Thus, the objects defined with "first", "second", etc. may explicitly or implicitly include one or more of such objects. Also, similar terms such as "one" or "a" do not indicate a quantity limitation but rather indicate the existence of at least one, and "multiple" means not less than two.
[0045] Figures 1 to 6 Shows a blanket-type magnetic resonance coil device (hereinafter, sometimes simply referred to as the device) provided according to an embodiment of this application, where Figures 1 to 4 Shows the configuration of the device in a flattened state even when not in use, Figure 5 Shows the configuration of the device in a deformed state even when in use. The device includes a deformable flexible blanket 1 and a plurality of coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p supported by the flexible blanket 1. The device can perform combined magnetic resonance imaging examinations on the thyroid gland and the shoulder and neck of the subject PP, which helps in the judgment of the condition. For example, it helps to detect the spread and metastasis of thyroid lesions.
[0046] In some embodiments, each of the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p is encapsulated inside the flexible blanket 1, that is, between two opposite surfaces of the flexible blanket 1, and each of the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p has at least two connection points with the flexible blanket 1. For example, each of the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p can be connected to the flexible blanket 1 along its entire length. In this way, when a force is applied to the flexible blanket 1 and it deforms, the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p supported by the flexible blanket 1 will also deform accordingly and are not easily damaged structurally. As a result, during actual use, the device, especially each of the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p in the device, can closely adhere to the body of the subject PP, thus helping to improve the quality of magnetic resonance examination.
[0047] The device further has an outlet box 5 installed at the edge of the second part 12. The cable (not shown in the figure) is led out through the outlet opening 51 of the outlet box 5 and is coupled to each of the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p. The cable is used to transmit electrical signals between the coil units 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p and an external computing device. The main structure of the outlet box 5 can be made of plastic material.
[0048] Please also refer to Figures 1 to 4 , the flexible blanket 1 includes a first part 11 and a second part 12 that are connected to each other. The first part 11 has two first sub - parts 11R, 11L separated left and right, and these two first sub - parts 11R, 11L are used to cover the right and left sides of the subject PP's neck respectively. The second part 12 has two second sub - parts 12R, 12L separated left and right, and these two second sub - parts 12R, 12L are used to cover the shoulders of the subject PP respectively. In Figures 1 to 4In the shown flattened state, two first sub-parts 11R and 11L are respectively and separably stacked with two second sub-parts 12R and 12L. And, based on switching the first sub-parts and the second sub-parts from the stacked form with each other to the non-stacked form separated from each other, the two first sub-parts 11R and 11L respectively cover the left and right sides of the neck of the subject PP, and the two second sub-parts 12R and 12L respectively cover the shoulders of the subject PP.
[0049] In this embodiment, for the second part 12, there is a hollowed-out area between its two second sub-parts 12R and 12L, and this hollowed-out area is used to receive the neck of the subject PP in the use state. For the first part 11, its two first sub-parts 11R and 11L are connected to each other via other parts of the first part 11, and no hollowed-out area is formed between the two first sub-parts 11R and 11L (the two first sub-parts 11R and 11L and these other parts are generally in a rectangular shape as a whole), and this other part is used to cover the neck of the subject from the front side in the use state.
[0050] Please refer to again Figures 1 to 4 And in combination with Figure 5 , the part of the first part 11 between the two first sub-parts 11R and 11L is connected to the part of the second part 12 between the two second sub-parts 12R and 12L at the third connection boundary 1a. And, the third connection boundary 1a is in a substantially straight line shape extending along the left-right direction DR2 of the subject PP. Through such a design, the dimensions of the third connection boundary 1a, the first sub-parts, and the second sub-parts in the left-right direction DR2 are independent of each other. On the one hand, the length of the third connection boundary 1a connecting the first part 11 and the second part 12 in the left-right direction DR2 can be set to be appropriately small, so that the first part 11 as a whole and the second part 12 as a whole can be easily folded relative to each other around the third connection boundary 1a, and then the first part 11 can be easily close to the cheek of the subject PP, and the second part 12 can be easily close to the front chest of the subject PP. And the coil units 4j, 4k, 4l are arranged in the part of the flexible blanket 1 (more specifically, the second part 12 of the flexible blanket 1) for covering the front chest of the subject PP, which helps to optimize the quality of magnetic resonance examination. On the other hand, the dimensions of the first sub-parts 11R and 11L and the second sub-parts 12R and 12L in the left-right direction DR2 can be set to be large enough to cover the cheeks and shoulders of the subject PP on a sufficient area, further optimizing the quality of magnetic resonance examination.
[0051] Please continue to refer to Figures 1 to 4 And in combination with Figure 5, the first sub - parts 11R, 11L have first outer edges 11R1, 11L1, and the second sub - parts 12R, 12L have second outer edges 12R1, 12L1. Among them, the first outer edges 11R1, 11L1 extend in a substantially L - shape, while the second outer edges 12R1, 12L1 extend in a substantially U - shape. And when observed along the stacking direction DR1 of the first sub - parts 11R, 11L and the second sub - parts 12R, 12L, the first outer edges 11R1, 11L1 and the second outer edges 12R1, 12L1 define a closed curve. In Figure 1 it, the closed curve is substantially rectangular.
[0052] Please also combine with Figure 2 and Figure 5 , the stacking direction DR1 of the first sub - parts 11R, 11L and the second sub - parts 12R, 12L corresponds to the front - to - back direction of the subject PP.
[0053] Please refer to Figure 2 , the third connection boundary 1a terminates with the second outer edge.
[0054] Please continue to refer to Figures 1 to 4 and combine with Figure 5 , when observed along the stacking direction DR1 of the first sub - parts 11R, 11L and the second sub - parts 12R, 12L, one end of the first outer edges 11R1, 11L1 extends to the second outer edges 12R1, 12L1 but not to the ends of the second outer edges 12R1, 12L1. That is, one end of the first outer edges 11R1, 11L1 extends to a non - end position of the second outer edges 12R1, 12L1. Through such a design, at the termination parts CR, CL of the third connection boundary 1a and the second outer edges 12R1, 12L1, there are no first outer edges 11R1, 11L1 of the first sub - parts 11R, 11L. Therefore, compared with the case where one end of the first outer edges 11R1, 11L1 extends to the aforementioned termination parts CR, CL, this embodiment can avoid interference between the first sub - parts 11R, 11L and the second sub - parts 12R, 12L at the aforementioned termination parts CR, CL, and helps to eliminate possible bulges at the termination parts CR, CL in the Figures 1 to 4 shown flattened state.
[0055] Continue to refer to Figure 2, the first sub - parts 11R, 11L also have first connection boundaries 11R2, 11L2 connected to the first part 11. The first connection boundaries 11R2, 11L2 and the aforementioned first outer edges 11R1, 11L1 enclose and define the first sub - parts 11R, 11L. Similarly, the second sub - parts 12R, 12L have second connection boundaries 12R2, 12L2 connected to the second part 12. The second connection boundaries 12R2, 12L2 and the aforementioned second outer edges 12R1, 12L1 enclose and define the second sub - parts 12R, 12L. When observed along the stacking direction DR1 of the first sub - parts 11R, 11L and the second sub - parts 12R, 12L, the first connection boundaries 11R2, 11L2 and the second connection boundaries 12R2, 12L2 do not overlap.
[0056] Please also combine Figure 2 and Figure 5 , the first sub - parts 11R, 11L are configured to be able to fold and deform integrally around a part of the first connection boundaries 11R2, 11L2 (specifically, the length segments of the first connection boundaries 11R2, 11L that extend in the raising direction DR3). The second sub - parts 12R, 12L are configured to be able to fold and deform integrally around the second connection boundaries 12R2, 12L2. In this embodiment, the aforementioned part of the first connection boundaries 11R2, 11L2 extends in the height direction DR3 of the subject PP, and the second connection boundaries 12R2, 12L2 extend in the left - right direction DR2 of the subject PP. Therefore, the extending directions of the aforementioned part of the first connection boundaries 11R2, 11L2 and the second connection boundaries 12R2, 12L2 cross each other, for example, are perpendicular to each other.
[0057] In this embodiment, at least a part 4d1, 4g1 of at least one coil unit 4d, 4f is supported by the first sub - parts 11R, 11L and deforms following the deformation of the first sub - parts 11R, 11L. At least a part 4h1, 4i1 of at least another coil unit 4h, 4i is supported by the second sub - parts 12R, 12L and deforms following the deformation of the second sub - parts 12R, 12L.
[0058] Specifically, a part 4d1 of the coil unit 4d is supported by the first sub - part 11R, a part 4f1 of the coil unit 4f is supported by the first sub - part 11L, a part 4h1 of the coil unit 4h is supported by the second sub - part 12R, and a part 4i1 of the coil unit 4i is supported by the second sub - part 12L. When the first sub - part 11R deforms, a part 4d1 of the coil unit 4d follows the deformation of the first sub - part 11R. When the first sub - part 11L deforms, a part 4g1 of the coil unit 4g1 follows the deformation of the first sub - part 11L. When the second sub - part 12R deforms, a part 4h1 of the coil unit 4h follows the deformation of the second sub - part 12R. When the second sub - part 12L deforms, a part 4i1 of the coil unit 4i follows the deformation of the second sub - part 12L.
[0059] In some other embodiments, all of one or several coil units 4 are supported by the first sub - part 11R (when observed along the stacking direction DR1, all of the one or several coil units 4 fall within the interior of the first sub - part 11R), and when the first sub - part 11R deforms, the one or several coil units 4 follow its deformation.
[0060] Please refer to Figure 5 , in this embodiment, the second part 11 is also used to cover the face of the subject PP. In particular, the two first sub - parts 11R and 11L respectively cover the cheeks of the subject PP (for example, the two first sub - parts 11R and 11L respectively cover a small part of the cheeks of the subject PP, while other parts of the second part 11 cover most of the cheeks of the subject PP). In addition, the part of the second part 12 other than the second sub - parts 12R and 12L can cover the front chest of the subject PP.
[0061] The first part 11 has an opening 13 which is used for exposing the mouth and / or nose of the subject PP during the magnetic resonance examination, so as to increase the conformity between the first part 11 and the face of the subject PP, and help the subject PP breathe smoothly and improve the user experience. In Figure 1 , the opening 13 is a through - hole with a closed edge, and the coil unit 4b is arranged around the periphery of the through - hole. In some other embodiments, the opening 13 can be a notch recessed inward from the outer edge of the first part 11.
[0062] In some embodiments, the device further includes an elastically deformable headband, the shape of which is similar to a U - shaped extended headphone, and is configured to clamp and fix the flexible blanket 1 (more specifically, the first part 11 of the flexible blanket 1) on the head of the subject.
[0063] Please review Figure 1, in this embodiment, the device further includes an elastically flexible edge reinforcement structure 2, which is joined to the edge portion of the flexible blanket 1.
[0064] In some embodiments, the elastic restoring force of the edge reinforcement structure 2 biases the flexible blanket 1 towards Figures 1 to 4 the flattened state shown, or rather, through the elastic restoring force of the edge reinforcement structure 2 itself, the device, especially the flexible blanket 1 of the device, can be easily maintained in Figures 1 to 4 the flattened state shown, which helps to reduce the size and occupied space of the device in the non-use state.
[0065] As Figure 6 shown, the edge reinforcement structure 2 includes elastic ribs 21 and a fabric 22 that wraps the elastic ribs 21, and the fabric 22 is stitched and connected to the edge portion of the flexible blanket 1 via stitches 3.
[0066] Based on the above description and in combination with Figure 2 、 Figure 5 and Figure 7 , an embodiment of the present application also provides a usage method of the device, and the method includes:
[0067] S701, arranging the flexible blanket 1 on the front side of the subject PP in a manner such that the lamination direction DR1 corresponds to the front-back direction of the subject PP, wherein the first sub-parts 11R, 11L are laminated on the front side of the second sub-parts 12R, 12L.
[0068] Exemplarily, the subject PP can lie on the examination bed in a supine position, and the staff covers the flattened device in front of the subject PP (i.e., the direction towards which the face of the subject PP faces, so when the subject PP lies on the examination bed in a supine position, this front also corresponds to the upper side of the subject PP in the direction of gravity), and the first sub-parts 11R, 11L are more towards the front of the subject PP than the second sub-parts 12R, 12L.
[0069] S702, folding the first sub-parts 11R, 11L around the height direction DR3 of the subject PP to cover the neck of the subject PP, and during this process, the second sub-parts 12R, 12L are folded around the left-right direction DR2 of the examiner PP under the force applied by the first sub-parts 11R, 11L to cover the shoulders of the subject PP.
[0070] As Figure 1 and Figure 2, in this embodiment, the first outer edges 11R1, 11L1 of the first sub-parts 11R, 11L have first outer extension segments 11R1a, 11L1a that are outward in the left-right direction of the subject PP, and the second outer edges 12R1, 12L1 of the second sub-parts 12R, 12L have second outer extension segments 12R1a, 12L1a that are outward in the left-right direction of the subject PP. Moreover, in the left-right direction DR2 of the subject PP, the second outer extension segments 12R1a, 12L1a are more outward than the first outer extension segments 11R1a, 11L1a. In this way, it is possible to easily achieve the aforementioned step S702, that is, when the first sub-parts 11R, 11L are folded around the height direction DR3 of the subject PP, the second sub-parts 12R, 12L can be automatically and smoothly folded around the left-right direction DR2 of the examiner PP under the force applied by the first sub-parts 11R, 11L. As a result, the device can be easily worn on the body of the subject PP.
