The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

At present, a head coil or a head and neck combined coil is generally used in an existing magnetic resonance system to image the head and simultaneously display images of eyes, a nose bridge and other parts. However, the head coil and the head and neck combined coil have a large internal space, so that the coil is far away from the eyes and the nose of a human body, resulting in a low signal-to-noise ratio and a poor imaging effect. In order to obtain a clear eye image, a magnetic resonance imaging system special for human eyes exists in the prior art, but a nose abdicating notch has to be formed to avoid a raised nose bridge, so that a coil can be close to the human eyes to perform magnetic resonance imaging on the eyes. However, the magnetic resonance imaging system dedicated for the eyes of the human body cannot perform the magnetic resonance imaging on the nose of the human body while performing the magnetic resonance imaging on the eyes of the human body.

In order to solve the above problems, the present application designs a coil specially applied to the eyes and the nose of a human body, which can make the eye coil and the nose coil respectively and correspondingly close to the eyes and the nose bridge of the human body, so as to simultaneously perform magnetic resonance imaging on the eyes and the nose of the human body, and contribute to improving the imaging effect of performing magnetic resonance on the eyes and the nose.

Specifically, referring to fig. 1 to 5, an embodiment of the present application provides an eye-nose shared coil device 1, which includes an ergonomic base 10 and a radio frequency antenna 20 for fitting to an eye-nose portion of a human body. The radio frequency antenna 20 comprises an eye coil 21 and a nose coil 22 which are correspondingly arranged in the ergonomic base body 10, wherein the eye coil 21 is used for correspondingly approaching the human eyes to perform eye magnetic resonance imaging, and the nose coil 22 is used for correspondingly approaching the human nose to perform nose magnetic resonance imaging.

It should be noted that, since the ergonomic substrate 10 of the present application is adapted to the eye and nose of the human body, so that the ergonomic substrate 10 can be attached to the eye and nose of the human body, when the coil device 1 is used for magnetic resonance scanning, the ergonomic substrate 10 is attached to the eye and nose of the human body, so that the eye coil 21 and the nose coil 22 of the rf antenna 20 can be respectively and correspondingly close to the eye and the nose of the human body, so as to perform magnetic resonance imaging simultaneously, which is helpful to obtain clear eye images and nose images.

More specifically, as shown in fig. 1 to 4, the ergonomic base 10 includes an eye base 11 adapted to eyes of a human body and a nose base 12 adapted to a nose of a human body, and the eye base 11 and the nose base 12 are correspondingly arranged so that the nose base 12 is fitted to the nose of the human body when the eye base 11 is fitted to the eyes of the human body. Meanwhile, the eye coil 21 is correspondingly arranged in the eye base 11, and the nose coil 22 is correspondingly arranged in the nose base 12, so as to ensure that the eye coil 21 and the nose coil 22 can respectively approach and fit to the eyes and the nose of the human body.

Preferably, the ocular base 11 is integrally connected to the nasal base 12 to form the ergonomic base 10 having a unitary construction.

More preferably, as shown in fig. 1, the eye base 11 of the ergonomic base 10 is provided with a window 110 corresponding to an eye of a human body, for avoiding the eye, so that the eye base 11 fits the eye of the human body more closely, so as to ensure that the eye coil 21 is closer to the eye of the human body. It can be understood that, when the eye-nose shared coil device 1 is used, the window 110 of the eye base 11 can correspond to the eyes, which not only can avoid the eye-nose shared coil device 1 from exerting physical pressure on the eyes of the human body and help protect the eyes, but also can observe the surrounding environment through the window 110 and relieve the psychological stress of the user.

Most preferably, as shown in FIG. 2, nose body 12 of ergonomic base 10 bulges outward from eye body 11 for snugly covering the human nose. In other words, the nose base 12 has a covering space 120 for receiving a bridge of the nose, so that when the eye-nose shared coil apparatus 1 is used, the covering space 120 of the nose base 12 receives a bridge of the nose, so that the nose base 12 tightly covers the nose of the human body, so that the nose coil 22 can be closer to the nose of the human body.

For example, as shown in fig. 1 and 2, the eye base 11 of the ergonomic base 10 may be provided with two windows 110 to correspond to two eyes of a human body, respectively; and the covering space 120 of the nose base 12 is located between the two windows 110 to correspond to the bridge of the nose of the human body. It is understood that in other examples of the present application, the eye base 11 of the ergonomic base 10 may be provided with only one larger window to correspond to both eyes of the human body, which is not described in detail herein.

It is noted that, as shown in fig. 1 to 3, the ergonomic base 10 may be composed of an outer shell 101 and an inner liner 102 which are stacked to wrap the rf antenna 20 between the outer shell 101 and the inner liner 102. It should be understood that the outer shell layer 101 mentioned in this application refers to a base layer on the ergonomic substrate 10 away from the human body, and the inner liner layer 102 refers to a base layer on the ergonomic substrate 10 close to the human body; that is, when the eye-nose shared coil apparatus 1 is used, the inner liner layer 102 contacts the human body, but the outer shell layer 101 does not contact the human body.

Illustratively, the outer shell layer 101 and the inner liner layer 102 may be connected together by, but not limited to, heat pressing or sewing, so as to form a space for accommodating the rf antenna 20 inside the ergonomic base 10, so that the rf antenna 20 is wrapped by the ergonomic base 10, and the human body is prevented from directly contacting the rf antenna 20.

Preferably, the ergonomic base 10 is made of a flexible material such as foamed EVA, artificial leather or PU leather. In other words, the ergonomic base 10 has a certain flexibility so as to be finely adjusted according to the shape and size difference of the eyes and nose of the human body during use, so as to better fit the eyes and nose of the human body.

More preferably, outer shell 101 with inner liner 102 is prepared by the flexible material of different kinds, and the material hardness of outer shell 101 is greater than the material hardness of inner liner 102, in order to pass through outer shell 101 does when the eye nose sharing coil device 1 provides supporting strength, can also pass through inner liner 102 makes the eye nose sharing coil device 1 laminates the human body better, improves the comfort level of human use. It is understood that in other examples of the present application, the outer shell layer 101 and the inner liner layer 102 may also be made of the same flexible material.

According to the above-mentioned embodiment of the present application, the eye coil 21 in the rf antenna 20 is mainly used for contributing rf signals for eye imaging, and the nose coil 22 in the rf antenna 20 is mainly used for contributing rf signals for nose imaging. In other words, the eye coil 21 and the nose coil 22 of the rf antenna 20 are each provided with some distributed capacitance for generating resonance at a specific frequency to contribute to the rf signals for eye imaging and nose imaging, respectively.

Preferably, the eye coil 21 and the nose coil 22 in the radio frequency antenna 20 may be, but are not limited to being, implemented as closed coils each made of a conductive material provided with a distributed capacitance. Alternatively, the conductive material may be, but is not limited to, implemented as a copper substrate, a liquid metal, a coaxial line, or a conductive silver paste. It will be understood that the eye coil 21 and the nose coil 22 are relatively independent, i.e. the eye coil 21 and the nose coil 22 are not in communication with each other, each forming a closed loop.

More preferably, the rf antenna 20 has a conformal structure, that is, the structure of the rf antenna 20 matches the contour of the eye and nose of the human body, so that the rf antenna 20 can better fit the eye and nose of the human body. In other words, the radio frequency antenna 20 adopts a conformal design, so that the shape of the eye coil 21 is adapted to the human eye, so as to be close to the human eye in a fitting manner; and the nose coil 22 is shaped to fit the human nose so as to fit snugly adjacent the human nose.

Illustratively, in the first example of the present application, as shown in fig. 4 and 5, the radio frequency antenna 20 may include two eye coils 21 and one nose coil 22, wherein the two eye coils 21 are correspondingly disposed on the eye base 11 of the ergonomic base 10 from left to right for respectively corresponding to the left eye and the right eye of the human body, and the one nose coil 22 is correspondingly disposed on the nose base 12 of the ergonomic base 10 to be located below between the two eye coils 21 for corresponding to the bridge of the nose of the human body.

Preferably, both eye coils 21 extend to the nose base 12 to partially overlap within the nose base 12 to increase the coil density at the nose base 12, which helps to improve the nose signal-to-noise ratio and improve the clarity of the nose image.

More preferably, one nose coil 22 and two eye coils 21 are partially overlapped in the nose base 12, so that the coil density corresponding to the nasal root is further increased, which helps to obtain a clearer image of the nasal root.

It should be noted that, in the second example of the present application, as shown in fig. 6, the radio frequency antenna 20 may also include one eye coil 21 and one nose coil 22, wherein one eye coil 21 corresponds to both eyes of the human body, and one nose coil 22 is partially overlapped with the eye coil 21 to correspond to the bridge of the nose of the human body.

Furthermore, in the third example of the present application, as shown in fig. 7, the radio frequency antenna 20 may also include one eye coil 21 and two nose coils 22, wherein one eye coil 21 corresponds to both eyes of the human body at the same time, and two nose coils 22 are partially overlapped on the nose base 12 to correspond to the nose bridge of the human body at the same time. Optionally, the nose coil 22 is further partially overlapped with the eye coil 21 to increase the coil density at the nose base 12.

It is understood that, although the above various examples may include one or two eye coils 21 and nose coils 22 in the radio frequency antenna 20, they are only examples, and in other examples of the present application, the number of the eye coils 21 or the nose coils 22 may also exceed two, so as to correspondingly increase the coil density and further improve the magnetic resonance imaging effect.

It should be noted that, according to the above-mentioned embodiment of the present application, as shown in fig. 1 to fig. 3, the eye-nose shared coil apparatus 1 may further include an auxiliary mechanism 30, wherein the auxiliary mechanism 30 is connected to the ergonomic substrate 10 for captively holding the ergonomic substrate 10 to the eye-nose portion of the human body, so as to ensure that the ergonomic substrate 10 is stably attached to the eye-nose portion of the human body.

It can be understood that, because the ergonomic substrate 10 of the present application has a certain flexibility, when the ergonomic substrate 10 is constrained to the eye and nose of the human body by the auxiliary mechanism 30, the ergonomic substrate 10 may slightly deform to better fit the eye and nose of the human body, so that the coil is closer to the eyes and the nose of the human body.

As shown in fig. 1 to 3, the auxiliary mechanism 30 may be embodied, but not limited to, as an elastic bandage 31. Thus, when the common eye-nose coil device 1 is used for magnetic resonance scanning, the ergonomic substrate 10 can be stably bound to the nose and eye of a human body by stretching the elastic bandage 31 to fit on the head of the human body. It is understood that the auxiliary mechanism 30 can be implemented as a structure such as a suspension loop or a strap, as long as the ergonomic base 10 can be bound to the nose and eye of the human body, which will not be described in detail herein.

It is noted that the elastic bandage 31 can be connected to the ergonomic base 10 by means of, but not limited to, heat pressing or sewing. It can be understood that the eye-nose shared coil device 1 can be used alone to perform magnetic resonance imaging specifically for the eye-nose part of the human body; of course, in other examples of the present application, the eye-nose shared coil device 1 may also cooperate with a head coil or a head-neck joint coil to perform joint scanning, so as to obtain a clearer eye image and a clearer nose image while obtaining a head or head-neck image.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
