[0002] Magnetic resonance imaging (MRI) is an important clinical imaging tool. Due to the presence of a strong magnetic field, it is difficult to add electronic indication signals within the magnets of existing nuclear magnetic resonance (NMR) scanners. As a result, patients are unaware of the progress of the magnetic scan and must wait for a diagnosis to be completed while lying still inside a confined magnet. Furthermore, because the space in most existing MRI scanners is cramped and enclosed, patients quickly become tense and restless during the waiting process, which compromises image quality. SUMMARY OF THE REGISTRATION PROCESS

[0003] In view of the aforementioned shortcomings of the prior art, one objective of the present application is to provide an imaging device for a magnetic resonance imaging (MRI) device in order to mitigate the problem that it is difficult to add electronic indication signals within the magnets of existing nuclear magnetic devices, so that a patient has to wait for a diagnosis to be completed while lying inside a magnet, but the patient quickly becomes tense and restless during the waiting process due to the confined and enclosed space in most existing MRI imaging devices, thereby impairing image quality.

[0004] To achieve the above objective and other related objectives, the present application proposes an imaging device for a magnetic resonance device, wherein the magnetic resonance device comprises an examination table and a magnetic resonance chamber, and wherein the imaging device comprises the following: a picture projection device located in a first room; An optical / electrical conversion module that is connected to the image display device via an optical fiber and converts an image emitted by the image display device into electrical signals; an electrical / optical conversion module that is connected to the optical / electrical conversion module and converts the electrical signals into the image; and a projection device which is connected to the electrical / optical conversion module by means of an image transmission assembly and is used to project the image onto an upper wall of the magnetic resonance chamber, wherein the image transmission assembly comprises at least one image transmission lens group and / or an image transmission optical fiber bundle; and wherein the magnetic resonance device, the optical / electrical conversion module, the electrical / optical conversion module and the projection device are located in a second room and the first room and the second room are electromagnetically shielded from each other.

[0005] In one embodiment of the present application, the electrical / optical conversion module is an optical DLP engine.

[0006] In one embodiment of the present application, the projection device is arranged at one end of a table body of the examination table, which is near the magnetic resonance chamber.

[0007] In one embodiment of the present application, the imaging device further comprises an electromagnetic shielding box which is mounted within a base of the examination table, wherein the optical / electrical conversion module and the electrical / optical conversion module are arranged within the electromagnetic shielding box.

[0008] In one embodiment of the present application, the image transmission lens group is mounted within a base of the examination table or on a table body of the examination table.

[0009] In one embodiment of the present application, the image transmission assembly comprises an image transmission lens group and an image transmission optical fiber bundle, and two ends of the image transmission optical fiber bundle are connected to the image transmission lens group and the projection device, respectively.

[0010] In one embodiment of the present application, the projection device comprises a support and an image projection lens group, wherein the support is mounted at one end of a table body of the examination table which is near the magnetic resonance chamber, and the image projection lens group is attached to the support.

[0011] In one embodiment of the present application, the support comprises an optical fiber bundle mounting structure and an end of the image transmission optical fiber bundle, which is remote from the image transmission lens group, is attached to the optical fiber bundle mounting structure.

[0012] In one embodiment of the present application, an axis of one end of the image transmission optical fiber bundle, which is attached to the optical fiber bundle mounting structure, is collinear with an axis of the image projection lens group.

[0013] In one embodiment of the present application, the support is detachably mounted on the table body and comprises a support base and a mounting frame, wherein the support base is detachably mounted on the table body and the mounting frame is rotatably connected to the support base.

[0014] In one embodiment of the present application, a projection film is further included, wherein the projection film is arranged on the upper wall of the magnetic resonance chamber and the image is projected onto the projection film.

[0015] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device. The imaging device converts an image emitted by an image projection device into electrical signals using an optical-to-electrical conversion module. These electrical signals are then converted back into an image using an electrical-to-optical conversion module. The image is then transmitted by means of an image transmission assembly to a projection device, which projects the image into the interior of a magnetic resonance chamber for viewing by a patient undergoing the examination. This process calms the patient and ensures that the examination proceeds normally. A method of photoelectric separation is employed. A lens group and an image transmission optical fiber bundle are used to guide an image from outside the magnet to inside the magnet, thus preventing interference from electromagnetism.In addition, the image is converted into electrical signals using the optical / electrical conversion module and the electrical / optical conversion module, and then converted back into an image that is transmitted and projected onto the interior of the magnetic resonance chamber to improve the projection quality of the image, with greater benefit for viewing by the patient.

[0016] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device. In the imaging device, an image transmission lens group is arranged within an examination table, such that the image transmission lens group replaces part of an image transmission optical fiber bundle in order to simultaneously perform the function of image size reduction and image transmission, thus replacing a structure in which the entire image transmission is carried out by the image transmission optical fiber bundle. This reduces costs and prevents the movement of a table body from being affected by the optical fiber bundle, since the entire image transmission is carried out by the image transmission optical fiber bundle.

[0017] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device, wherein an upper wall of a MRI chamber is provided with a projection film, and an image is ultimately projected onto the projection film to increase the image resolution. Furthermore, if the distance between a patient's eyes and the upper wall of the MRI chamber is small, this can easily produce an uncomfortable sensation. Therefore, the present application uses the image projection lens group to perform a projection capable of achieving such an effect that the image is moved further away, thus increasing the patient's viewing comfort. The patient can view the image directly without relying on devices such as glasses or a mirror for viewing.

[0018] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device.

The drawings show only relevant components in the present application and are not drawn according to the numbers, shapes, and dimensions of components as they are actually implemented; the shapes, numbers, and proportions of the various components, when actually implemented, can be modified as desired, and the layout of the components may also be more complex.

[0022] With reference to Fig. 1 and Fig. 2. The present application provides an imaging device for a magnetic resonance imaging (MRI) device to mitigate the problem that it is difficult to add electronic indication signals within the magnets of existing nuclear magnetic devices, so that a patient has to wait for a diagnosis to be completed while lying inside a magnet, whereby the patient quickly becomes tense and restless during the waiting process due to the confined and enclosed space in most existing MRI devices, thereby impairing image quality. In the present embodiment, the imaging device is suitable for use in certain existing MRI devices 100;For example, the magnetic resonance device comprises a lifting assembly 110, an examination table 120, and a scanning mechanism 130, wherein the examination table 120 comprises a base 1021 and a table body 1022, the base 1021 being mounted on the lifting assembly 110, the table body 1022 being slidably mounted on the base 1021, and a magnetic resonance chamber 101 also being formed in the scanning mechanism 130, and during an examination, the table body 1022 slides into the magnetic resonance chamber 101 and a scan is performed. In the present embodiment, the imaging device comprises an image output device 10, an optical / electrical conversion module 20, an electrical / optical conversion module 30, an image transmission assembly 40, and a projection device 50; The image projection device 10 is located in a first room and is used for projecting images;The optical / electrical conversion module 20 is connected, for example, to the image display unit 10 by means of an optical fiber 11 and is used to convert an image emitted by the image display unit 10 into electrical signals; the electrical / optical conversion module 30 is connected to the optical / electrical conversion module 20 and is used to convert the electrical signals back into the image; and the projection device 50 is connected to the electrical / optical conversion module 30 by means of the image transmission assembly 40 in order to project the image onto an upper wall of the magnetic resonance chamber 101. Furthermore, in the present embodiment, the magnetic resonance device 100, the optical / electrical conversion module 20, the electrical / optical conversion module 30 and the projection device 50 are located in a second room, and the first room and the second room are electromagnetically shielded from each other.

[0023] With reference to Fig. 1 and Fig. 2 In the present embodiment, the image projection device 10 is used to project images and can be designed as a device, such as a computer, capable of projecting images and video; for example, the images can be a timer, breathing instructions, or a film. In the present embodiment, the image projection device 10 can be provided with a signal conversion module that converts the image into optical signals, and the optical-to-electrical conversion module 20 is connected to the signal conversion module by means of an optical fiber, so that the optical signals are converted into electrical signals. In some other embodiments, the image can also be converted into electrical signals by means of another device.In the present embodiment, the optical-to-electrical conversion module 20 is arranged, for example, within the base 1021; in particular, an electromagnetic shielding box 12 is provided in the base 1021, and the optical-to-electrical conversion module 20 is mounted within the electromagnetic shielding box 12. In the present embodiment, the electromagnetic shielding box 12 need not contain elements such as iron, cobalt, nickel, etc., and can, for example, be designed as a structure made of red copper or aluminum to achieve an electromagnetic shielding effect, thereby further preventing interference from electromagnetism.

[0024] With reference to Fig. 1 and Fig. 2 In the present embodiment, the electrical / optical conversion module 30 is mounted inside the electromagnetic shielding box 12 and is connected to the optical / electrical conversion module 20 so that the electrical signals are converted into the image; for example, the electrical / optical conversion module 30 can be designed as an optical DLP engine, wherein the optical DLP engine is used to restore the electrical signals to form the image output by the image output device 10.It must be explained that during an examination of a patient, the optical / electrical conversion module 20 and the electrical / optical conversion module 30 are both located outside the magnetic resonance chamber 101, that is, far away from the magnetic resonance chamber 101, which to some extent prevents the electromagnetism of the magnetic resonance chamber 101 from interfering with these electronic devices, thus ensuring their normal operation; in addition, both modules are located inside the electromagnetic shielding box 12 to further prevent electromagnetism from interfering with them.It must be explained that in the present application, the image is converted into electrical signals by means of the optical / electrical conversion module 20 and the electrical / optical conversion module 30 and then converted back into an image, which is transmitted and projected into the interior of the magnetic resonance chamber; compared to direct projection by a projector in a conventional structure, the present application can improve the projection quality of the image, for example by increasing the brightness of the image, with greater benefit for viewing by a patient.

[0025] With reference to Fig. 1 and Fig. 2 In the present embodiment, the projection device 50 is connected to the electrical / optical conversion module 30 by means of the image transmission assembly 40, for example, the projection device 50 is connected to the optical DLP engine by means of the image transmission assembly 40, so that the image recovered by the optical DLP engine is transmitted to the projection device 50 by means of the image transmission assembly 40 and projected onto the upper wall of the magnetic resonance chamber 101 by means of the projection device 50.

[0026] With reference to Fig. 1 and Fig. In the present embodiment, the image transmission assembly 40 comprises at least one image transmission lens group 41 and / or an image transmission optical fiber bundle 42, and the image is transmitted to the projection device 50 by means of the image transmission lens group 41 and / or the image transmission optical fiber bundle 42. For example, the image transmission assembly 40 comprises the image transmission lens group 41 and the image transmission optical fiber bundle 42; two ends of the image transmission optical fiber bundle 42 are connected to the image transmission lens group 41 and / or the projection device 50, respectively.In the image transmission process, after repeated projection and scaling via the image transmission lens group 41, a real-time image, which has a reduced size, is finally projected onto a terminal end of the image transmission optical fiber bundle 42, which is connected to the image transmission lens group 41, and by means of the image transmission optical fiber bundle 42, the image is transmitted to an end of the image transmission optical fiber bundle 42 that is far from the image transmission lens group 41, and finally the projection device 50, which is connected to the image transmission optical fiber bundle 42, projects the image onto the upper wall of the magnetic resonance chamber 101;That is, the image transmission lens group 41 replaces at least part of the image transmission optical fiber bundle 42, and the image transmission lens group 41 simultaneously performs the function of image size reduction and image transmission in order to replace a structure in which the entire image transmission is carried out by the image transmission optical fiber bundle, thus reducing the costs and preventing the movement of the table body from being affected by the optical fiber bundle, because the entire image transmission is carried out by the image transmission optical fiber bundle. It must be explained that the image transmission lens group 41 can be arranged in the base 1021 and can, of course, also be arranged on the table body 1022 in order to replace at least part of the image transmission optical fiber bundle;Naturally, the image transmission lens group 41 can be partially arranged in a gap between a lower wall of the magnetic resonance chamber 101 and the table body 1022. Of course, in some other embodiments, the image transmission assembly 40 can also be provided only with the image transmission lens group 41 or the image transmission optical fiber bundle 42 to perform image transmission.

[0027] With reference to Fig. 1 and Fig. In the present embodiment, an adjustment lens 13 is provided between the optical DLP engine and the image transmission lens group 20; the adjustment lens 13 is used to adjust the position and size of the image so that the image is projected more accurately onto the image transmission lens group 20. In some other embodiments, the adjustment lens 13 can be moved between the optical DLP engine and the image transmission lens group 20 to adapt the adjustment lens to different image transmissions.

[0028] With reference to Fig. 1 and Fig. In the present embodiment, the projection device 50 is arranged at an end of the table body 1022 that is near the magnetic resonance chamber 101; for example, the projection device 50 comprises an image projection lens group 51 and a support 52, wherein the support 52 is mounted at an end of the table body 1022 that is near the magnetic resonance chamber 101, wherein the image projection lens group 51 is fixedly mounted on the support 52, wherein an end of the image transmission optical fiber bundle 42, which is far from the image transmission lens group 41, passes through the underside of the table body 1022 and is connected to the image projection lens group 51, so that the image is transmitted to the image projection lens group 51, which projects the image into the magnetic resonance chamber 101.It must be explained that if the distance between a patient's eyes and the upper wall of the magnetic resonance chamber 101 is small, this can easily produce an unpleasant sensation, and thus the present application uses the image projection lens group 51 to perform a projection capable of achieving such an effect as to move the image further away in order to increase the patient's viewing comfort.

[0029] With reference to Fig. 1 and Fig. 2 In the present embodiment, the upper wall is provided with a projection film 1011 and the image is projected onto the projection film 1011; the projection film 1011 can, for example, be a transparent projection film; the image projection lens group 51 projects the image onto the upper wall of the interior of the magnetic resonance chamber 101 in order to increase the resolution of the image so that the patient can view the image directly without needing to use devices such as glasses or a mirror for viewing.

[0030] With reference to Fig. 1 and Fig. 2 In the present embodiment, the support 52 is detachably mounted on the table body 1022 to facilitate replacement or maintenance of the image projection lens assembly 51 as required; the support 52 is mounted at an end of the table body 1022 that is near the magnetic resonance chamber 101, and the image projection lens assembly 51 is fixedly mounted on the support 52; the support 52 can move together with the table body 1022 to avoid frequent adjustment of its position. It must be explained that, in the present application, an end of the table body 1022 that is near or far from the magnetic resonance chamber 101 refers to an end part of the table body 102 that is near / far from the magnetic resonance chamber 101 before the table body was moved into the magnetic resonance chamber 101.In the present embodiment, the support 52 comprises a support base and a mounting frame, wherein the support base is detachably connected to the table body 1022, wherein the mounting frame is rotatably connected to the support base, and wherein the image projection lens group 51 is fixedly mounted on the mounting frame to allow adjustment of an angle of the image projection lens group 51 according to requirements, thereby facilitating use by patients in different positions.

[0031] With reference to Fig. 1 and Fig.In the present embodiment, the support 52 is further provided with an optical fiber bundle mounting structure, wherein one end of the image transmission optical fiber bundle 42, which is furthest from the image transmission lens group 41, is attached to the optical fiber bundle mounting structure to ensure that one end of the image transmission optical fiber bundle 42, which is near the image projection lens group 51, always remains fixed relative to the image projection lens group 51, thus preventing image projection from being affected by movement of the table body. In the present embodiment, an axis of one end of the image transmission optical fiber bundle 42, which is attached to the optical fiber bundle mounting structure, is collinear with an axis of the image projection lens group 51 to ensure projection quality.In some other embodiments, when the image transmission lens group 41 is fixedly mounted in the base 1021, the length of the image transmission optical fiber bundle 42 is greater than the distance between one end of the table body 1022, which is provided with the image projection lens group 51 when the table body 1022 is located inside the magnetic resonance chamber 101, and the image transmission lens group 41, in order to avoid excessive pulling on the image transmission optical fiber bundle 42 and consequently damaging it when the table body moves, and furthermore an electromagnetic shielding layer is wrapped around the outside of the image transmission optical fiber bundle 42 to prevent electromagnetic interference, thereby improving the projection quality.It must be explained that in the present embodiment, the optical fiber bundle mounting structure and the mounting frame are an integral structure, so that during an angular adjustment of this structure, the image transmission optical fiber bundle 42 and the image projection lens group 51 are able to rotate synchronously, which can prevent the image transmission optical fiber bundle 42 and the image projection lens group 51 from being displaced relative to each other after an angular adjustment and impairing image projection.

[0032] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device. The imaging device converts an image emitted by an image projection device into electrical signals using an optical-to-electrical conversion module. These electrical signals are then converted back into an image using an electrical-to-optical conversion module. The image is then transmitted by means of an image transmission assembly to a projection device, which projects the image into the interior of a magnetic resonance chamber for viewing by a patient undergoing the examination. This process calms the patient and ensures that the examination proceeds normally. A method of photoelectric separation is employed. A lens group and an image transmission optical fiber bundle are used to guide an image from outside the magnet to inside the magnet, thus preventing interference from electromagnetism.In addition, the image is converted into electrical signals using the optical / electrical conversion module and the electrical / optical conversion module, and then converted back into an image that is transmitted and projected onto the interior of the magnetic resonance chamber to improve the projection quality of the image, with greater benefit for viewing by the patient.

[0033] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device. In the imaging device, an image transmission lens group is arranged within an examination table, such that the image transmission lens group replaces part of an image transmission optical fiber bundle in order to simultaneously perform the function of image size reduction and image transmission, thus replacing a structure in which the entire image transmission is carried out by the image transmission optical fiber bundle. This reduces costs and prevents the movement of a table body from being affected by the optical fiber bundle, since the entire image transmission is carried out by the image transmission optical fiber bundle.

[0034] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device, wherein an upper wall of a MRI chamber is provided with a projection film, and an image is ultimately projected onto the projection film to increase the image resolution. Furthermore, if the distance between a patient's eyes and the upper wall of the MRI chamber is small, this can easily produce an uncomfortable sensation. Therefore, the present application uses the image projection lens group to perform a projection capable of achieving such an effect that the image is moved further away, thus increasing the patient's viewing comfort. The patient can view the image directly without relying on devices such as glasses or a mirror for viewing.

[0035] The present application proposes an imaging device for a magnetic resonance imaging (MRI) device. In the imaging device, an axis of one end of an image transmission optical fiber bundle, which is attached to the optical fiber bundle mounting structure, is collinear with an axis of the image projection lens group in order to improve the projection quality; at the same time, an angle of a support is adjustable to allow use by patients in different positions.
