[0002] Magnetic resonance imaging technology is widely used in biomedical and neuroscience research due to its high resolution, non-invasiveness, and full-scale imaging. The design and development of radio frequency coils are based on the physical basis of MRI signal generation and acquisition, where the Z-axis direction is generally defined as the direction parallel to the horizontal direction of the MRI bed, the Y-axis direction is perpendicular to the Z-axis direction and parallel to the horizontal plane of the MRI bed, and the X-axis direction is perpendicular to the Z-axis and Y-axis directions.

[0003] In the existing technology, the head MRI positioning device used in the hospital imaging department is often an integrated structure, which leads to limitations in the process of collecting head MRI images of some patients. This limiting effect is not good, resulting in poor MRI image collection effect after the MRI image is collected.

[0004] After searching, it is found that a Chinese patent document discloses an optimized positioning device suitable for head nuclear magnetic resonance imaging (publication number: CN115363563B). This technical solution discloses an optimized positioning device suitable for head nuclear magnetic resonance imaging. The device fixes the surface coil and the surface coil array at the center of the nuclear magnetic resonance static magnetic field, parallel to the direction of the magnetic field, and adjusts the target cortex to be located at the center of the nuclear magnetic resonance magnetic field according to the imaging area of ​​the subject's head, and is closer to the coil, thereby obtaining the best imaging signal-to-noise ratio of the subject's head imaging area. The head fixing device includes: a coil fixing device that can be adjusted in the front and back, up and down directions according to the imaging area of ​​the subject's head, a semi-cylindrical base that can be rotated in any direction of the nuclear magnetic resonance bed, a dental tray that can be adjusted in angle, a head clamping device that can be adjusted in the front and back, up and down directions according to the size and position of the subject's head, and a nuclear magnetic resonance bed clamping device.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Example 1

[0036] See also Figure 1-Figure 4 The present invention provides a head MRI positioning device for a hospital imaging department, comprising a head MRI positioning frame 101, the inner side wall of the head MRI positioning frame 101 of the clamping slot is an arc-shaped structure, and the outer side wall of the head MRI positioning frame 101 penetrates and is fixedly connected with a plurality of mounting frames 106, both ends of the inner side of the mounting frame 106 of the clamping slot are symmetrically and fixedly connected with flexible sheets 110, and one end of the flexible sheet 110 is equidistantly and fixedly connected with a second limiting protrusion 109, the outer side wall of the second limiting protrusion 109 of the clamping slot conflicts with the outer side wall of the first limiting protrusion 108, and the first limiting protrusion 108 and the second limiting protrusion 109 are both semi-cylindrical structures, the second limiting protrusion 109 of the clamping slot is symmetrically and fixedly connected to the two ends of a movable block 107 at an equal distance, and the movable block 107 penetrates and is movably connected to the inside of the mounting frame 106, and one end of the movable block 107 of the clamping slot is provided with a connecting cavity 112.

[0037] By setting up the installation frame 106, when the movable block 107 inside the installation frame 106 moves toward the head MRI positioning frame 101, the movable block 107 changes the size of the head wrapping balloon 102, so that the head wrapping balloon 102 forms a limiting component of appropriate size, thereby limiting the head of the patient who needs to undergo MRI. At the same time, when the head MRI positioning frame 101 is separated from the pushing block 309 set inside the placement box 301, the first limiting protrusion 108 conflicts with the outer wall of the first limiting protrusion 108, so that the movable block 107 is self-limited.

[0038] One end of the movable block 107 of the snap-in groove is fixedly connected to the outer wall of one end of the connecting cavity 112, and the inner end of the connecting cavity 112 is movably connected with a guide block 114, one end of the snap-in groove guide block 114 is fixedly connected to the outer wall of the head wrapped balloon 102, and the other end of the guide block 114 is connected to the outer wall of the elastic balloon 113, the snap-in groove elastic balloon 113 is fixedly connected to the inner end of the connecting cavity 112, the head wrapped balloon 102 of the snap-in groove is an arc-shaped structure, and the inner wall of the head wrapped balloon 102 is bonded and fixedly connected with the first male Velcro 103 with a velvet structure, the outer wall of the first male Velcro 103 of the snap-in groove is bonded and fixedly connected with the first female Velcro 104 with a hook structure, and the first female Velcro 104 is fixedly connected to the rear end outer wall of the first medical disposable gasket 105.

[0039] By setting the movable block 107, the movable block 107 can be moved during use, thereby pushing the connecting cavity 112 and the guide block 114 to move relative to the center point of the head wrapping balloon 102, thereby squeezing the head wrapping balloon 102 to change the size of the head wrapping balloon 102, thereby meeting the head size of the patient undergoing MRI. At the same time, in the process of changing the size of the head wrapping balloon 102, the head needs of patients with deformities can be met. At the same time, after the head wrapping balloon 102 is adjusted, the elastic balloon 113 is set, so that when the head wrapping balloon 102 is squeezed by the head, the guide block 114 moves toward the inside of the connecting cavity 112 and squeezes the elastic balloon 113. In this way, the size of the head wrapping balloon 102 leaves room for squeezing, while ensuring the stability in the acquisition of MRI images, the comfort of the patient is further improved.

[0040] When the embodiment of the present application is used: first, the moving block 107 is pushed to move inside the mounting frame 106 by cooperating with the pushing block 309 and other components;

[0041] Secondly, when the movable block 107 inside the mounting frame 106 moves toward the head MRI positioning frame 101, the movable block 107 changes the size of the head wrapping balloon 102, so that the head wrapping balloon 102 forms a limiting component of appropriate size, and the movable block 107 is self-locked;

[0042] Afterwards, after the head wrapping balloon 102 is adjusted, the elastic balloon 113 is provided so that the head wrapping balloon 102 is squeezed by the head, and the guide block 114 moves toward the inside of the connecting cavity 112 and squeezes the elastic balloon 113, so that the size of the head wrapping balloon 102 leaves a squeezing space;

[0043] Finally, after the previous patient uses such a head MRI positioning device for the hospital imaging department, the first medical disposable gasket 105 is replaced, because the first medical disposable gasket 105 is bonded to each other by the first male Velcro 103 and the first female Velcro 104, so that the first medical disposable gasket 105 is easy to disassemble and assemble. At the same time, all materials in this embodiment are suitable for magnetic resonance imaging.

[0044] Example 2

[0045] See also Figure 4 and Figure 5 The present invention provides a head MRI positioning device for a hospital imaging department, including a head MRI positioning frame 101. During MRI detection, the head MRI positioning frame 101 is clamped inside the top ends of two first clamping grooves 202. The first clamping grooves 202 are symmetrically fixedly connected to the top end of a positioning plate 201, and both sides of the positioning plate 201 are fixedly connected with clamping plates 209 with an "L"-shaped structure, and the corresponding vertical outer walls of the clamping plates 209 are fixedly connected with interference balloons 210.

[0046] The head MRI positioning frame 101 that needs to undergo head MRI is clamped by the first clamping groove 202 provided at the top of the positioning plate 201, and is clamped to the top of the delivery end of the delivery component of the MRI device through the clamping plate 209. The pressure generated by the squeezing of the resisting balloon 210 is used to improve the stability after connection with the delivery end of the delivery component of the MRI device. The segmented design reduces the cost of later maintenance and is more convenient during subsequent maintenance and cleaning.

[0047] A groove is provided at the top of the positioning plate 201, and a back-of-head wrapping balloon 205 is buckled inside the groove, and a plurality of connecting buckles 204 are fixedly connected to the bottom end of the back-of-head wrapping balloon 205, and the bottom ends of the connecting buckles 204 are buckled inside the top of the buckle seat 203, and the buckle seats 203 are fixedly connected to the inner bottom end of the groove, and the top of the back-of-head wrapping balloon 205 is fixedly connected to a second male Velcro 206 with a suede structure, and the top of the second male Velcro 206 is bonded to the bottom of the second female Velcro 207, and the top of the second female Velcro 207 is fixedly connected to the bottom end of the second medical disposable gasket 208.

[0048] By setting up the second medical disposable gasket 208, medical cleanliness is ensured during use. At the same time, when the back of the patient's head hits the second medical disposable gasket 208, it will press the back of the head downward to wrap the balloon 205, thereby improving the patient's comfort during the MRI process. In addition, because the second medical disposable gasket 208 is fixedly connected by the second male Velcro 206 and the second female Velcro 207, the quick-release design further improves the convenience of maintenance of the device during use.

[0049] When the embodiment of the present application is used: firstly, the head MRI positioning frame 101 of the adjustable head wrapping balloon 102 is connected and fixed, and the head MRI positioning frame 101 is clamped and limited through the first clamping groove 202;

[0050] Secondly, the positioning plate 201 is clamped to the top of the delivery end of the delivery component of the nuclear magnetic resonance device through the clamping plate 209, and the stability of the delivery end of the delivery component of the nuclear magnetic resonance device after connection is improved by resisting the pressure generated by the squeezing of the balloon 210;

[0051] Afterwards, when the back of the patient's head hits the second disposable medical pad 208, the back of the head will be pressed downward to wrap the balloon 205, thereby improving the patient's comfort during the MRI process;

[0052] Finally, because the second medical disposable gasket 208 is fixedly connected by the second male Velcro 206 and the second female Velcro 207, the second medical disposable gasket 208 can be quickly replaced after the current patient uses it through the quick-release design. At the same time, all materials in this embodiment are suitable for nuclear magnetic resonance.

The head nuclear magnetic resonance positioning frame 101 is stored in a placement box 301 during daily storage and when a head wrapping balloon 102 arranged inside the head nuclear magnetic resonance positioning frame 101 is adjusted. An image processing module 311 is fixedly connected to the top of the placement box 301, and an image acquisition device 312 is fixedly connected to the top of the image processing module 311. The image acquisition device 312 is electrically connected to the image processing module 311. The image processing module 311 includes an image analysis module and a control module. The outer walls on both sides of the head nuclear magnetic resonance positioning frame 101 are symmetrically fixedly connected with hinges, and the hinges are hinged with a front cover plate 310. The front cover plate 310 is closed at the front end of the placement box 301 through the hinges.

[0055] By setting up the image processing module 311, the patient's head parameter information is collected through the image processing module 311 in cooperation with the image acquisition device 312 during use, and the size of the head wrapping balloon 102 set inside the corresponding head magnetic resonance imaging positioning frame 101 stored in the placement box 301 is adjusted.

[0056] The image analysis module is used to collect head image data through the image acquisition device 312 when the patient who needs to undergo MRI stands in the designated area, and transmit the collected head image data to the image analysis module, and analyze the patient's head size data through the image analysis module, and obtain the patient's head size data, and transmit the obtained patient's head size data to the control module;

[0057] The function of the control module is to construct the corresponding pushing block 309 set outside the head MRI positioning frame 101 to push the data according to the patient head size data transmitted by the image analysis module, and send the corresponding control instructions to the motor 308 through the pushing data to enable the motor 308 to complete the data operation.

The inner bottom end of the placement frame 302 is fixedly connected with an ultraviolet sterilization lamp 303 for ultraviolet sterilization of the head MRI positioning frame 101 and other components.

[0059] By setting up the ultraviolet sterilization lamp 303, during use, after the internal clamping of the head MRI positioning frame 101 is connected to the placement frame 302, the ultraviolet sterilization lamp 303 is started to sterilize the head MRI positioning frame 101 with ultraviolet light, and at the same time, the head MRI positioning frame 101 and other components are clamped to the inside of the placement frame 302 to complete the storage operation.

[0060] The rear inner wall of the placement frame 302 is fixedly connected with sliding cavities 304 at equal intervals, and the interior of the sliding cavities 304 is movably connected with sliding blocks 305, one end of the sliding blocks 305 is fixedly connected with a pushing block 309, one end of the pushing block 309 corresponds to one end of the connecting cavity 111 opened at one end of the corresponding movable block 107, and the interior of the sliding block 305 is fixedly connected with a connecting screw sleeve 306, the inner side wall of the connecting screw sleeve 306 is meshed with a transmission screw 307, and the transmission screw 307 is rotatably connected between the inner walls on both sides of the sliding cavity 304, and one end of the transmission screw 307 is linked to the output end of the motor 308.

[0061] By setting up the motor 308, after receiving the control instruction, the motor 308 outputs at a uniform speed, and then drives the transmission screw 307 to rotate forward through the motor 308, so that the transmission screw 307 cooperates with the connecting screw sleeve 306 to form a screw transmission structure, and then drives the sliding block 305 to slide inside the sliding cavity 304, and drives the pushing block 309 to move synchronously, so that the pushing block 309 is plugged into the inside of the connecting cavity 111, and pushes the movable block 107 to move a specified distance, thereby changing the size of the head wrapping balloon 102. However, after the size of the head wrapping balloon 102 is adjusted, the transmission screw 307 is driven by the motor 308 to rotate in the opposite direction, so that the sliding block 305 and the pushing block 309 are reset.

[0062] When the embodiment of the present application is used: first, the image acquisition device 312 acquires the head information of the patient, and then transmits the acquired head image data to the image analysis module through the image processing module 311, and analyzes the head size data of the patient through the image analysis module, and obtains the head size data of the patient, and transmits the obtained head size data of the patient to the control module;

[0063] Secondly, the control module constructs the corresponding pushing data of the pushing block 309 set outside the head MRI positioning frame 101 according to the patient head size data transmitted by the image analysis module, and sends the corresponding control instructions to the motor 308 through the pushing data, so that the motor 308 completes the data operation;

However, after the size of the head wrapping balloon 102 is adjusted, the transmission screw 307 is driven by the motor 308 to rotate in the opposite direction, so that the sliding block 305 and the pushing block 309 are reset;

[0065] Finally, after the internal clamping joint MRI positioning frame 101 of the placement frame 302 is connected, the ultraviolet sterilization lamp 303 is started to perform ultraviolet sterilization on the head MRI positioning frame 101, and thus a head MRI positioning device for the imaging department of a hospital is ready for use.
