Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic resonance imaging, in particular to a shoulder wearable coil. Background Art
[0002] The closer the MRI receiving coil fits the scanned part, the higher the image quality. However, in actual clinical scanning, due to the differences in the structural sizes of the scanned parts of patients, it is basically impossible to achieve the best fit for each patient.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A partial schematic diagram of a shoulder-wearable coil provided by an embodiment of the utility model when unfolded. Figure 2 A partial schematic diagram of a shoulder-wearable coil provided in one embodiment of the utility model. Figure 3 A schematic diagram of the cooperation between a shoulder-wearable coil and a detection object provided by an embodiment of the utility model. Figure 4A schematic diagram of the coordination between the flexible conductive wire and the wearable device in the shoulder wearable coil provided in one embodiment of the utility model. The shoulder wearable coil provided in one embodiment of the utility model includes a wearable device 100 and a flexible conductive wire 240. The wearable device 100 includes a first sheet 110 and two second sheets 120. The first sheet 110 and the two second sheets 120 are both provided with flexible conductive wires 240. The two second sheets 120 are respectively arranged on the left and right sides of the first sheet 110, and partially overlap with the first sheet 110. When the wearable device 100 wraps around the shoulder of the detection object, the second sheet 120 can move relative to the first sheet 110, so that the detection space of the wearable device 100 adapts to the shoulder of the detection object.
[0038] Specifically, in the present application, the first layer 110 is used to be attached to the acromion area and upper arm area of the shoulder of the detection object 300, so that the relative position of the wearable device 100 and the detection object 300 is fixed, and the two second layers 120 are respectively used to be attached to the chest area and scapular area of the shoulder of the detection object 300, and the second layer 120 is moved relative to the first layer 110 to change the area of the corresponding overlapping area 170 of the second layer 120 and the first layer 110, thereby changing the size of the chest area or scapular area of the shoulder of the detection object 300 covered by the second layer 120, and the position of the second layer 120 relative to the first layer 110, so as to adapt to the detection objects 300 of different body shapes or different shoulder thicknesses, so as to achieve the best fit with the detection object 300, and the first layer 110 and the two second layers 120 are provided with flexible conductive wires, then the first layer 110 and the second layer 120 are both receiving coils, and the flexible conductive wires can be easily deformed, so as to facilitate adaptation to the shoulders of the detection objects. During the magnetic resonance imaging process, since the wearable device 100 can better fit the shoulder of the detection object 300, the quality of the obtained image can be improved.
[0039] Among them, the detection object 300 can wear the wearable device 100 freely on the shoulder, and only needs to lie on the bed after entering the scanning room. Compared with the scanning method in the prior art, there is no need to position the coil in advance, and let the center of the patient's scanned part approach the center of the coil, thereby greatly reducing the complexity of positioning and reducing the time of positioning.
[0040] It should be noted that the two second sheets 120 are completely consistent, so that the shoulder wearable coil can adapt to the left shoulder and the right shoulder. The outer layer of the wearable component 100 is encapsulated by a flexible material such as felt, polyurethane (PU), etc., and adopts a hot pressing or sewing process, has a certain degree of flexibility, and can be bent to a certain extent.
[0041] See also Figure 1 and Figure 3In one embodiment, the wearable device 100 further includes a first strap 130, one end of the first strap 130 is connected to one of the two second layers 120, and the other end is connected to the first layer 110, and the first strap 130 is capable of expansion and contraction to change the area of the overlapping region 170 between the corresponding second layer 120 and the first layer 110.
[0042] Specifically, the first strap 130 is provided so that the second layer 120 can move relative to the first layer 110 to change the area of the overlapping region 170, and at the same time, can play a limiting role to ensure that the second layer 120 is stably attached to the chest area or scapular area of the shoulder of the detection object 300. Preferably, the first strap 130 is an elastic strap.
[0043] Furthermore, there are two first binding straps 130, and the two second sheets 120 are respectively connected to the first sheet 110 through the first binding straps 130. In other embodiments, there may be more than one first binding strap 130.
[0044] Furthermore, one end of the first binding strap 130 is connected to an edge region of the second sheet layer 120 close to the first sheet layer 110 , and the other end is connected to an edge region of the first sheet layer 110 close to the corresponding second sheet layer 120 .
[0045] In another embodiment, one end of the first strap 130 is connected to one of the two second layers 120, and the other end is connected to the other of the two second layers 120. The first strap 130 can be extended and retracted, so as to change the distance between the two second layers 120, and further change the distance between the second layer 120 and the first layer 110. The first strap 130 is connected to one end of the two second layers 120 that are close to each other, so as to ensure that a pulling force is applied to each second layer 120 toward the first layer 110, so as to ensure that the second layer 120 partially overlaps with the first layer 110, so as to improve the reliability of the shoulder wearable coil.
[0046] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the wearable device 100 further includes a second strap 140, one end of the second strap 140 is connected to one of the two second layers 120, and the other end is connected to the other of the two second layers 120, and the second strap 140 is used to be sleeved on the detection object 300 and tension the two second layers 120.
[0047] Specifically, the first strap 130 is used to tension the ends of the two second layers 120 that are close to each other, and the second strap 140 is used to tension the ends of the two second layers 120 that are away from each other, so that the two second layers 120 can be stably limited on the detection object 300 to maintain a stable fit with the chest area or scapular area of the detection object 300, further improving the reliability of the shoulder wearable coil.
[0048] Furthermore, the second strap 140 can be retracted, so that it can adapt to more detection objects 300 of different body shapes without changing the area of the overlapping area 170 between the second layer 120 and the first layer 110, thereby improving the adaptability of the shoulder wearable coil. Preferably, the second strap 140 is an elastic band. The second strap 140 can be passed from the front chest to the armpit on the non-scanning side, or it can be passed around the neck.
[0049] Furthermore, the second strap 140 is detachably connected to at least one of the two second sheets 120, so that the second strap 140 can be sleeved on the detection object 300 to improve the convenience of the detection object 300 wearing the wearable device 100. In one embodiment, the second strap 140 is bonded to at least one of the two second sheets 120. In one embodiment, the ends of the two second sheets 120 that are away from each other are both provided with Velcro 150, and the Velcro 150 is used to bond with the second strap 140.
[0050] See also Figure 1 and Figure 3 In one embodiment, the first sheet layer 110 includes a first part 111 and a second part 112, both of which are provided with flexible conductive lines. The second sheet layer 120 and the second part 112 are both connected to the first part 111. The two second sheets 120 are respectively located on both sides of the first part 111 and partially overlap with the second part 112 respectively. The second sheet layer 120 can move relative to the second part 112 to change the area of the corresponding overlapping region 170.
[0051] Specifically, the first part 111 is used to be attached to the upper arm area of the shoulder of the test subject 300, and the second part 112 is used to be attached to the acromion area of the shoulder of the test subject 300. Since the shoulder thickness of the test subjects 300 with different body shapes varies greatly, the second layer 120 is connected to the second part 112 through the first strap 130, so that the position of the second layer 120 can be adjusted more conveniently, so that the second layer 120 can fit the chest area or scapular area of the shoulder of the test subjects 300 with different shoulder thicknesses.
[0052] In other embodiments, the second sheet layer 120 may be connected to the first portion 111 through the first binding strap 130 , or the second sheet layer 120 may be connected to the first portion 111 and the second portion 112 respectively through the first binding strap 130 .
[0053] See also Figure 1 and Figure 3 In one embodiment, the first layer 110 further includes a third strap 160, two ends of which are respectively connected to the opposite ends of the first portion 111, so as to define a mounting hole with the first portion 111 for the upper arm of the detection object 300 to pass through, and the third strap 160 is retractable.
[0054] Specifically, the third strap 160 can be retracted and retracted, thereby being able to adjust the size of the mounting hole, so that the first part 111 can be stably mounted on the upper arm of the detection object 300, so that the wearable device 100 and the shoulder of the detection object 300 are relatively fixed. At the same time, it can also adapt to detection objects 300 with different arm thicknesses, thereby improving the reliability and adaptability of the shoulder wearable coil.
[0055] Further, the third strap 160 includes a first connecting strap 161 and a second connecting strap 162, and the first connecting strap 161 and the second connecting strap 162 are respectively connected to the two ends of the first part 111, and when the first connecting strap 161 and the second connecting strap 162 are connected, they can be surrounded by the first part 111 to form a mounting hole. The first connecting strap 161 and the second connecting strap 162 are detachably connected, so that the upper arm of the detection object 300 is conveniently passed through the mounting hole, thereby improving the convenience of wearing the wearable device 100. Preferably, the first connecting strap 161 and the second connecting strap 162 are bonded.
[0056] In one embodiment, one of the first connecting belt 161 and the second connecting belt 162 is an elastic belt, and the other is provided with a Velcro 150, and the bonding is achieved through the Velcro 150. In other embodiments, the third binding belt 160 can be extended and retracted by changing the position of bonding with the Velcro 150.
[0057] See also Figure 1 and Figure 3 In one embodiment, the first layer 110 is arc-shaped, specifically, the first portion 111 and the second portion 112 are both arc-shaped, so as to facilitate adaptation to the acromion area and upper arm area of the shoulder of the detection object 300, so that the first portion 111 is more closely fitted to the detected part of the detection object 300.
[0058] See also Figure 1 and Figure 2 In one embodiment, the second sheet layer 120 is in a planar shape, so as to facilitate adaptation to the chest area or shoulder area of the detection object 300, so as to better fit the detection area of the detection object 300.
[0059] See also Figure 1 and Figure 3In one embodiment, the first layer 110 has an arc-shaped notch 113 in the area between the two second layers 120 to avoid the neck of the detection object 300, so that the wearable device 100 fits the shoulders of the detection object 300 better.
[0060] Furthermore, one end of the first portion 111 close to the second sheet layer 120 is arc-shaped to fit the base of the upper arm of the detection object 300 .

That is, in the present application, the amplifier 210 is arranged on the outside of the wearable device 100, so that the wearable device 100 is thinner and lighter, so as to fit the detection object 300 more closely.
