Description

Technical Field

[0001] The present invention belongs to the technical field of imaging equipment, and in particular relates to an imaging lens adjustment device and an adjustment method. Background Art

[0002] Brain imaging irradiates the brain through corresponding imaging equipment to image the brain structure. Through this imaging process, medical personnel can understand the relationship between specific brain areas and their functions, locate brain areas affected by neurological diseases, and invent new methods to treat brain diseases. At the same time, according to the existing public document CN118614944B, it can be known that it discloses a method of controlling the rotation of a large gear ring by driving a drive motor to control the rotation of the X-ray lens and realize imaging.

[0003] Therefore, the imaging in the current equipment requires the X-ray tube and the detector to rotate around the patient at high speed to obtain multi-angle projection data, and the existing imaging equipment is driven by a high-precision servo motor or a brushless DC motor to ensure stable speed and accurate position to avoid image artifacts. However, in order to ensure the stability of imaging and avoid electromagnetic interference in the imaging process, the electromagnetic compatibility of the motor used will be optimized, and the electromagnetic compatibility optimization is to shield the motor and design a low-interference circuit to avoid electromagnetic interference to the X-ray detector and the electronic system. At the same time, most of the brain imaging equipment used uses X-rays to irradiate the brain to achieve brain imaging. In order to be able to image the brain at multiple angles, multiple sets of lenses and receivers are generally used to work together to image the brain. However, the use of multiple sets of lenses will cause interference between rays, resulting in the inability to effectively identify the imaging. A single set of lenses is used for position adjustment to achieve multi-angle imaging. However, this method requires the receiver to be controlled again for position adjustment. Since the position adjustment angle of the receiver cannot be accurately controlled to be consistent with the lens position adjustment, the imaging picture will be missing. To this end, we provide an imaging lens adjustment device and an adjustment method to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide an imaging lens adjustment device and an adjustment method. By arranging the multiple travel air nozzle ports on the two L-shaped ring plates in opposite directions, the X-ray lens can be controlled to rotate back and forth in the U-shaped ring frame, so that the position of the brain can be imaged by a single X-ray lens. At the same time, through the coordinated use of the retaining ring and the I-shaped sleeve, the retaining ring can avoid excessive pulling of the arc spring, thereby ensuring the synchronous movement of the X-ray lens and the imaging receiver, thereby ensuring accurate imaging.

The synchronous imaging component is arranged in the same direction and in a ring shape, including an imaging receiver located between two L-shaped ring plates and arranged in a ring-shaped symmetrical manner with the X-ray lens, and a block located directly below the imaging receiver. The front and rear end faces of the block are both provided with circular openings, and a metal plate is arranged inside each circular opening. The opposite end faces of the two L-shaped ring plates are both embedded with magnetic plates adsorbed to the metal plates. The linkage component includes two arc-shaped cylinders whose ends are respectively close to the same-direction surfaces of the block and the slider and are arranged along the circumference of the U-shaped ring frame. The other ends of the two arc-shaped cylinders are fixed with retaining rings, and the other sides of the retaining rings are fixed with arc springs, which are sliding components used to move the single-group lens assembly and the synchronous imaging assembly.

[0006] The present invention is further configured such that the sliding assembly includes a rotating cylinder sleeved on an axis between the X-ray lens and the slider, the imaging receiver and the block, and an annular slide rail is fixed at the positions of the rotating cylinder on the opposite end surfaces of the two L-shaped ring plates.

[0007] The present invention is further configured such that a plurality of slide plates respectively located at inner and outer sides of the annular slide rail are fixed to the peripheral side wall of the rotating cylinder, and ball blocks respectively connected to the inner and outer sides of the annular slide rail are rotatably arranged inside the ball openings opened at the end faces of the slide plates.

[0008] The present invention is further configured such that square openings are opened at the positions of the two symmetrical end faces of the slider relative to the L-shaped ring plate, and inclined wind plates are fixed inside the square openings. The two inclined wind plates are symmetrically arranged in an "eight" shape, and the lower inclined surfaces of the inclined wind plates are arranged relative to the ports of the adjacent travel air nozzles.

[0009] The present invention is further configured such that each arc spring has an inner sliding end inserted into a positioning arc rod inside the arc tube and the retaining ring, and the other end of the positioning arc rod is fixed with a locking plate bolted to the same direction as the slider and the block.

[0010] The present invention is further configured such that the locking plate is fixedly connected to the adjacent end faces of the arc-shaped cylinders, and an I-shaped sleeve sleeved on the two arc-shaped cylinders is provided between the two locking plates.

[0011] The present invention is further configured such that the front and rear end faces of the block are provided with positioning holes connected to the inside of the circular opening, two positioning plates are fixed to the peripheral side walls of the metal plate and are respectively located inside the positioning holes, the inner end faces of the circular opening are provided with mounting grooves, and the inside of the mounting grooves are fixed with electromagnets for adsorbing the metal plates.

[0012] The present invention is further configured such that a through hole is provided on the inner end surface of each positioning opening, a plurality of movable holes respectively connected to the inside of the through holes are provided inside the block, and the aperture of the movable holes is larger than the aperture of the through holes.

[0013] The present invention is further configured such that the end faces of the positioning plates are fixed with moving rods passing through the internal position of the through holes, the end faces of the moving rods opposite to the positioning plates are fixed with moving plates slidingly connected to the inner side walls of the movable holes, and the end faces of the movable plates opposite to the moving rods are fixed with pushing springs abutting against the inner end faces of the movable holes.

[0014] The present invention also provides a method for adjusting an imaging lens, which is implemented by the following steps: S1: Control the travel air nozzle on a single L-shaped ring plate to work, whereby the travel air nozzle will push the inclined air plate to slide along the wind direction of the air flow through the high-speed airflow, thereby driving the slider and the X-ray lens to slide in the U-shaped ring frame; S2: After the slider moves, the slider pushes the arc tube and the arc spring to push the block to slide inside the U-shaped ring frame, thereby controlling the slider and the block to move synchronously; S3: After the X-ray lens is adjusted to the corresponding position, the electromagnet can be controlled to be powered off, so that the electromagnet will be separated from the adsorption relationship with the metal plate, and then the metal plate will be adsorbed and connected with the magnetic suction plate, so as to locate the position of the block and the position of the slider; S4: After the X-ray lens and the imaging receiver are adjusted to the corresponding positions, the human head is controlled to translate to the inner position of the U-shaped ring frame through the translation bed, so that the rays generated by the X-ray lens will penetrate the human brain and irradiate the imaging receiver, thereby achieving brain imaging.

[0015] The present invention has the following beneficial effects: The ventilation work of the stroke air nozzle is controlled, so that the stroke air nozzle will spray high-speed airflow to the position of the slider, and thereby push the slider to move inside the U-shaped ring frame, while driving the movement of the X-ray lens, which will cause the imaging receiver and the block to follow the sliding, and when the X-ray lens and the imaging receiver are controlled to stop moving, the metal plate is controlled to be adsorbed with the magnetic plate, so that the metal plate does not continue to move, thereby limiting the block, and then the block will control the X-ray lens to stop moving through the linkage component, ensuring the synchronous movement of the X-ray lens and the imaging receiver, and realizing the imaging of the brain position through a single X-ray lens, and at the same time abandoning the motor drive method and adopting airflow drive, without the need to use multiple electrical structures, thereby reducing the electromagnetic interference to the equipment.

[0016] When the slider is performing reverse reset rotation, the slider will drive the rotating cylinder connected to it to rotate, and will cause the retaining ring at that location to be disconnected from the arc spring, and make the retaining ring at that location connect to the I-shaped sleeve, and move the I-shaped sleeve so that the I-shaped sleeve abuts against the retaining ring on another rotating cylinder. Therefore, the I-shaped sleeve will drive the arc cylinder connected to the retaining ring to follow the movement, thereby driving the block to follow the movement of the slider and avoiding excessive pulling of the retaining ring on the arc spring, thereby ensuring the synchronous movement of the X-ray lens and the imaging receiver and ensuring accurate imaging.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0033] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Fig.10 and Fig.12 , which is the first embodiment of the present invention, provides an imaging lens adjustment device, through the opposite arrangement of the ports of the multiple travel air nozzles 103 on the two L-shaped ring plates, the X-ray lens 201 can be controlled to rotate back and forth in the U-shaped ring frame 101, so that the position of the brain can be imaged by a single X-ray lens 201, and at the same time, the retaining ring 401a and the I-shaped sleeve 403 are used in conjunction to avoid excessive pulling of the arc spring 404 by the retaining ring 401a.

[0034] Specifically, the annular mounting assembly 100 includes a U-shaped ring frame 101 and two L-shaped ring plates 102 symmetrically fixed on the front and rear symmetrical side walls of the U-shaped ring frame 101; the single-group lens assembly 200 includes an X-ray lens 201 located between the two L-shaped ring plates 102 and a slider 202 located at the port of the U-shaped ring frame 101 and consistent with the upper and lower positions of the X-ray lens 201; the synchronous imaging assembly 300 includes an imaging receiver 301 located between the two L-shaped ring plates 102 and arranged annularly symmetrically with the X-ray lens 201 and a block 302 located directly below the imaging receiver 301; the linkage assembly 400 includes an arc-shaped cylinder 401 whose ends are respectively close to the same surfaces of the block 302 and the slider 202 and are arranged along the circumference of the U-shaped ring frame; and a sliding assembly 500 for moving the single-group lens assembly 200 and the synchronous imaging assembly 300; By setting and using the above structure, the single-group lens assembly 200 slides inside the U-shaped ring frame 101, and the linkage assembly 400 drives the synchronous imaging assembly 300 to follow the single-group lens assembly 200 to slide synchronously inside the U-shaped ring frame 101, thereby ensuring the synchronous sliding of the linkage assembly 400 and the single-group lens assembly 200, so that the X-ray lens 201 can accurately irradiate the imaging receiver 301 when emitting rays, so as to perform imaging processing on the human brain. At the same time, after the single-group lens assembly 200 slides along the inner side of the U-shaped ring frame 101, different positions of the human brain can be irradiated to achieve a multi-angle imaging function. When using the device, the device is installed at the inner side of the CT device. Therefore, when imaging the patient's brain, the patient's brain can be translated into the U-shaped ring frame 101 with the help of an external translation bed. The rays generated by the X-ray lens 201 pass through the brain area and irradiate the imaging receiver 301, and the imaging receiver 301 performs imaging processing on it, and the image conversion is performed through multiple imaging machines such as an external computer.

[0035] according to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , the opposite end faces of the two L-shaped ring plates 102 are provided with annular grooves 102a, and the side walls of each L-shaped ring plate 102 are fixed with multiple stroke air nozzles 103 along the circumferential side and located inside the annular grooves 102a, the port positions of each two stroke air nozzles 103 of the two L-shaped ring plates 102 that are consistent in the front and rear directions are arranged in opposite directions, and the ports of the multiple stroke air nozzles 103 on each L-shaped ring plate 102 are arranged in the same direction and in a ring shape, the front and rear end faces of the block 302 are provided with mounting grooves 302b, and a metal plate 303 is arranged inside each mounting groove 302b, the opposite end faces of the two L-shaped ring plates 102 are embedded with magnetic suction plates 105 that are attracted to the metal plates 303, the other ends of the two arc-shaped cylinders 401 are fixed with retaining rings 401a, and the other side faces of the retaining rings 401a are fixed with arc springs 404; When using the above-mentioned structure, when it is necessary to control the X-ray lens 201 to slide inside the U-shaped ring frame 101, the ventilation work of the stroke air nozzle 103 can be directly controlled, so that the stroke air nozzle 103 will spray a high-speed airflow to the position of the slider 202, and thereby push the slider 202 to move inside the U-shaped ring frame 101, while driving the movement of the X-ray lens 201, and then the imaging receiver 301 and the block 302 will follow the sliding, and when the X-ray lens 201 and the imaging receiver 301 are controlled to stop moving, the metal plate 303 is controlled to be adsorbed with the magnetic plate 105, so that the metal plate 303 does not continue to move, thereby limiting the block 302, and then the block 302 will control the X-ray lens 201 to stop moving through the linkage component 400, to ensure the synchronous movement of the X-ray lens 201 and the imaging receiver 301, so that the position of the brain can be imaged by a single X-ray lens 201; When the slider 202 is rotating in the reverse direction, the slider 202 will drive the rotating cylinder 501 connected thereto to rotate, and the connection between the retaining ring 401a and the arc spring 404 will be disconnected, and the retaining ring 401a at that location will be connected to the I-shaped sleeve 403, and the I-shaped sleeve 403 will be moved to make the I-shaped sleeve 403 abut against the retaining ring 401a on another rotating cylinder 501, so that the I-shaped sleeve 403 will drive the arc cylinder 401 connected to the retaining ring 401a to follow the movement. The block 302 can be driven to follow the movement of the slider 202, and the retaining ring 401a can be prevented from excessively pulling the arc spring 404. Meanwhile, after the synchronous adjustment process of the X-ray lens 201 and the imaging receiver 301 is completed, the arc spring 404 will be compressed by the emergency stop of the X-ray lens 201 and the imaging receiver 301. Therefore, the elasticity of the arc spring 404 can be used to push and pull the imaging receiver 301, thereby reducing the sliding impact of the imaging receiver 301.

[0036] Further, according to Figure 3 , Figure 6 It can be seen that square openings 202a are provided at the positions of the two symmetrical end surfaces of the slider 202 relative to the L-shaped ring plate 102, and inclined wind plates 202b are fixed inside the square openings 202a. The two inclined wind plates 202b are symmetrically arranged in an eight-shaped shape, and the lower inclined surfaces of the inclined wind plates 202b are arranged relative to the ports of the adjacent travel air nozzles 103. The high-speed air flow blown out by the travel air nozzles 103 will blow to the position of the inclined wind plates 202b, thereby pushing the inclined wind plates 202b to move, thereby driving the sliding work of the slider 202. At the same time, the use of the two inclined wind plates 202b is to control the intermittent use of multiple travel air nozzles 103 on the two groups of L-shaped ring plates 102. When the inclined wind plates 202b correspond to the mouth positions of the travel air nozzles 103, the clockwise or counterclockwise rotation of the inclined wind plates 202b can be controlled in turn, thereby controlling the bidirectional sliding of the slider 202.

[0037] It should be noted that the multiple travel air nozzles 103 on the two L-shaped ring plates 102 are controlled and processed respectively by controlling the switchable air source to ensure that the travel air nozzles 103 on the two L-shaped ring plates 102 control the slider 202 to slide clockwise or counterclockwise inside the U-shaped ring frame 101 for switching processing. At the same time, the X-ray lens 201 and imaging receiver 301 used are controlled and processed by the external control center to ensure the reception of data information. Example 2

[0038] See also Figure 2 , Fig. 9 and Fig.11 On the basis of Example 1, this embodiment improves the sliding efficiency of the X-ray lens 201 and the imaging receiver 301 by rotating the rotating cylinder 501 through the slide plate 501a and the ball block 502 along the direction of the annular slide rail 104.

[0039] Specifically, the sliding assembly 500 includes a rotating cylinder 501 which is mounted on an axial rod between the X-ray lens 201 and the slider 202, and between the imaging receiver 301 and the block 302. Annular slide rails 104 are fixed at the positions of the rotating cylinder 501 on the opposite end surfaces of the two L-shaped ring plates 102 corresponding to the positions of the rotating cylinder 501. A plurality of slide plates 501a which are respectively located at the inner and outer sides of the annular slide rails 104 are fixed to the peripheral side walls of the rotating cylinder 501. A ball block 502 which is respectively connected to the inner and outer sides of the annular slide rails 104 is rotatably arranged inside a ball opening 501b opened on the end surface of the slide plate 501a.

[0040] By setting and using the above structure, when the block 302 and the slider 202 slide inside the U-shaped ring frame 101, the block 302 and the slider 202 will drive the rotating cylinder 501 to rotate, and thereby drive the slider 501a to rotate along the inner and outer positions of the annular slide rail 104, and at the same time drive the ball block 502 to rotate and slide along the inner and outer recessed positions of the annular slide rail 104, so as to improve the sliding efficiency of the X-ray lens 201 and the imaging receiver 301. Since the ball block 502 abuts against the inner side wall of the annular slide rail 104, and the slider 501a is also located at the inner side wall position of the annular slide rail 104, the cooperation between the slider 501a and the annular slide rail 104 will limit the rotating cylinder 501, and thereby limit the position of the slider 202 and the block 302, to ensure that the slider 202 and the block 302 are stably located in the U-shaped ring frame 101, and the position deviation of the X-ray lens 201 and the imaging receiver 301 can be avoided. Example 3

[0041] See also Figure 2 and Figure 4 On the basis of Example 1, this embodiment drives the movement of the arc tube 401 through the slider 202, so that the arc tube 401 can slide along the end of the positioning arc rod 402, ensuring that when the arc tube 401 compresses the arc spring 404, the arc spring 404 will be limited by the positioning arc rod 402, avoiding compression bending of the arc spring 404.

[0042] Specifically, the inner sliding part of the arc spring 404 has one end inserted into the inner position of the arc tube 401 and the retaining ring 401a, and the other end of the positioning arc rod 402 is fixed with a locking plate 402a bolted to the same direction as the slider 202 and the block 302, and the locking plate 402a is fixedly connected to the end surface of the arc tube 401 adjacent thereto, and an I-shaped sleeve 403 sleeved on the two arc tubes 401 is arranged between the two locking plates 402a; By setting and using the above structure, the I-shaped sleeve 403 is sleeved on the two arc-shaped sleeves 401, so that when the arc-shaped sleeve 401 follows the movement of the slider 202, the arc-shaped sleeve 401 will slide in the internal position of the I-shaped sleeve 403. At the same time, through the use of the locking plate 402a, the arc-shaped sleeve 401 can be installed and connected with the corresponding slider 202 and the block 302 respectively. The I-shaped sleeve 403 is located between the two retaining rings 401a, so the two retaining rings 401a limit the I-shaped sleeve 403, so that the slider 202 is pushed by the arc-shaped sleeve 401. When the moving block 302 slides, the arc tube 401 will slightly compress the arc spring 404, and thereby push the block 302 to move. When the arc tube 401 moves, the arc tube 401 will slide along the positioning arc rod 402. Since the positioning arc rod 402 is inside the arc spring 404, the positioning arc rod 402 limits the arc spring 404 to avoid excessive bending of the arc spring 404. When the arc tube 401 moves according to the slider 202 or the block 302, it can also move along the positioning arc rod 402. Example 4

[0043] See also Figure 5 , Figure 7 and Figure 8 On the basis of Example 1, this embodiment operates by turning the electromagnet 304 on and off to attract or detach the metal plate 303, thereby ensuring the stable positioning and movement of the block 302.

[0044] Specifically, the front and rear end surfaces of the block 302 are each provided with a positioning hole 302c connected to the inside of the circular opening 302a, and the peripheral side wall of the metal plate 303 is fixed with two positioning plates 303a respectively located inside the positioning hole 302c. The inner end surface of the circular opening 302a is provided with a mounting groove 302b, and the inside of the mounting groove 302b is fixed with an electromagnet 304 for adsorbing the metal plate 303. The inner end surface of each positioning hole 302c is provided with a through hole 302d, and the interior of the block 302 is provided with a plurality of through holes 302d respectively connected to the through holes 302d. The movable hole 302e is connected to the inside of the hole 302d, and the aperture of the movable hole 302e is larger than the aperture of the through hole 302d. The end surface of the positioning plate 303a is fixed with a moving rod 303c passing through the inner position of the through hole 302d. The end surface of the moving rod 303c opposite to the positioning plate 303a is fixed with a movable plate 303b slidably connected with the inner side wall of the movable hole 302e. The end surface of the movable plate 303b opposite to the moving rod 303c is fixed with a pushing spring 303d abutting against the inner end surface of the movable hole 302e. By setting and using the above structure, when it is necessary to control the block 302 and the sliding block to stop rotating in time, the electromagnet 304 can be controlled to be powered off, so that the electromagnet 304 and the metal plate 303 are separated from the adsorption relationship. At this time, the pushing spring 303d will push the movable plate 303b to move in the direction of the through hole 302d, and thereby push the moving rod 303c to slide in the through hole 302d, so that the positioning plate 303a is pushed out from the inside of the positioning port 302c, and the positioning plate 303a will drive the metal plate 303 to move out of the circular port 302a, and make the metal plate 303 connect with the magnetic plate 105, so that the metal plate 303 and the moving rod 303 are connected. 3c is used in conjunction with the block 302 to limit the position of the slider 202, thereby limiting the position of the imaging receiver 301 and the X-ray lens 201, and at the same time, after the electromagnet 304 is energized, the electromagnet 304 will adsorb the metal plate 303, thereby disconnecting the metal plate 303 from the magnetic plate 105, and the metal plate 303 will move into the circular opening 302a, and the metal plate 303 will drive the positioning plate 303a to move into the positioning opening 302c, thereby driving the moving rod 303c to control the movable plate 303b to slide in the movable air, thereby compressing the pushing spring 303d; It should be noted that the electromagnet 304 used is powered by an external power supply to ensure that the electromagnet 304 is powered on for a long time, so that the electromagnet 304 can always adsorb the metal plate 303. At the same time, the adsorption force generated by the electromagnet 304 is greater than the suction force generated by the magnetic suction plate 105, so that the metal plate 303 will fall off the magnetic suction plate 105. Example 5

[0045] On the basis of Example 1, multiple X-ray lenses 201 are integrated into an independent X-ray lens 201 to ensure the adjustment space during the rotation process of the X-ray lens 201 in the U-shaped ring frame 101. If a motor-driven method is adopted, it is necessary to install a corresponding motor, and a series of transmission structures such as gears or toothed belts that match the motor will also be used. However, the motor and other series of transmission structures will occupy the internal space of the equipment and compress the rotation space of the X-ray lens 201 in the U-shaped ring frame 101.

[0046] Specifically, the following table compares and distinguishes airflow drive from common drive methods: It can be seen from the above-mentioned driving methods that the U-shaped ring frame 101 cannot use hydraulic driving and pneumatic driving methods, and the motor driving method has electromagnetic interference and compression of the rotating space of the X-ray lens 201. Since the U-shaped ring frame 101 has a narrow internal space scene, it is suitable for airflow driving. Therefore, airflow driving is used as the main driving method of the X-ray lens 201; The positioning effect proposed at the same time is achieved through the effect of electromagnetic adsorption, but this effect is achieved by controlling the power off of the electromagnet 304, and the magnetic field of the electromagnet 304 after power off is very weak, and the electromagnet 304 is installed at the tail position of the imaging receiver 301, so it will not affect the sensitive components of the imaging device, and multiple stroke air nozzles 103 are installed in the annular groove 102a, so that the stroke air nozzles 103 are evenly distributed at a certain angle and correspond to the inclined wind plate 202b, so as to ensure that the high-speed airflow ejected by the stroke air nozzle 103 can push the inclined wind plate 202b to rotate at a certain angle.

[0047] It should be noted that airflow propulsion in the present invention is not only a power source, but also a comprehensive optimization solution: through the coordinated design of high-speed response, interference-free, two-way synchronization, and lightweight structure, imaging accuracy and operational efficiency are ensured. This choice fully meets the core requirements of imaging equipment for safety, accuracy and reliability. Example 6

[0048] The present invention also provides a method for adjusting an imaging lens, which is implemented by the following steps: S1: Control the travel air nozzle 103 on the single L-shaped ring plate 102 to work, so that the travel air nozzle 103 will push the inclined air plate 202b to slide along the wind direction of the air flow through the high-speed airflow, and thereby drive the slider 202 and the X-ray lens 201 to slide in the U-shaped ring frame 101; S2: After the slider 202 moves, the slider 202 pushes the arc tube 401, and the arc spring 404 pushes the block 302 to slide inside the U-shaped ring frame 101, thereby controlling the slider 202 and the block 302 to move synchronously; S3: After the X-ray lens 201 is adjusted to the corresponding position, the electromagnet 304 can be controlled to be powered off, so that the electromagnet 304 will be separated from the adsorption relationship with the metal plate 303, and then the metal plate 303 will be adsorbed and connected with the magnetic plate 105, so as to locate the position of the block 302, locate the position of the slider 202, and control the position of the X-ray lens 201 and the imaging receiver 301 to be stable; S4: After the X-ray lens 201 and the imaging receiver 301 are adjusted to corresponding positions, the human head is controlled to translate to the inner position of the U-shaped ring frame 101 by the translation bed, so that the rays generated by the X-ray lens 201 will penetrate the human brain and irradiate the imaging receiver 301, thereby achieving brain imaging.
