Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical equipment detection, in particular to a collimator aging detection device. BACKGROUND

[0002] A collimator, also known as a "line eliminator", "light reducer" or "light restrictor", is used to control the irradiation range of X-rays in medical X-ray diagnostic equipment to reduce radiation exposure to non-examination parts of the patient and improve imaging quality. The collimator is generally installed in the window of the X-ray tube cover and is used to block unnecessary primary X-rays during X-ray examination. During long-term use of the collimator, the performance of the various components contained in the collimator may decrease due to wear and aging, which not only affects the imaging quality but also increases the radiation risk to the patient. Therefore, aging detection of the collimator is crucial for ensuring medical X-ray imaging quality, reducing radiation risk, and improving equipment reliability.

[0003] However, in actual production, manufacturers can only set the angle of the collimator relative to its own rotation axis to a specific angle (e.g. 0°, 90° or 180°) for aging detection, and the detection scenario is relatively single. In addition, due to the lack of corresponding control programs and schemes, the internal components of the collimator can only move in a default manner during the aging detection process, and the grinding method is relatively single. Therefore, under the existing conditions, it is difficult for technicians to carry out comprehensive aging detection of the collimator, and the various moving parts inside the collimator cannot be fully ground. When the collimator is put into actual application, its opening precision and motion control cannot be effectively guaranteed, which leads to the inability to effectively control the irradiation range of X-rays, thereby threatening the health of the patient. CONTENT OF THE INVENTION

[0004] The purpose of the embodiments of the present application is to provide a collimator aging detection device that can simulate various stresses and environmental conditions that the collimator may encounter in actual use, carry out comprehensive and detailed aging detection of the collimator, and thus enable the collimator to be fully tested and ground.

[0005] The present application provides a collimator aging detection device, which includes a frame, a turntable and an adapter. The frame includes a base and a support, and the support is fixedly arranged on the base.

The adapter is fixedly connected to the surface of the turntable on the first side, and a collimator mounting position is arranged on the second side opposite to the first side.

[0006] In an implementable solution, the beam limiter aging detection device further comprises a stop device, which comprises a connecting portion fixedly connected with the support and a stop portion movably connected with the connecting portion. The stop device comprises a locked state and an unlocked state. In the locked state, the stop portion is in contact with the edge of the rotating disc, so that the rotating disc cannot rotate. In the unlocked state, the stop portion is separated from the edge of the rotating disc, so that the rotating disc can rotate normally.

[0007] In an implementable solution, the beam limiter aging detection device comprises at least two adapters, which are symmetrically distributed relative to the center of the rotating disc.

[0008] In an implementable solution, the beam limiter aging detection device comprises a driver fixedly arranged on the support and rotatably connected with the rotating shaft, for driving the rotating shaft to rotate around the center line thereof.

[0009] In an implementable solution, the beam limiter aging detection device comprises a controller connected with the beam limiter. The controller is internally provided with an aging detection program and a message monitoring program.

[0010] In an implementable solution, the controller is connected with the driver. The controller is internally provided with a rotating disc driving control program.

[0011] In an implementable solution, the rotating disc is provided with an angle sensor connected with the controller.

[0012] In an implementable solution, the rotating disc is provided with scale marks at the edge, for indicating the current angle of the adapter relative to the center of the rotating disc.

[0013] In an implementable solution, the second side of the adapter is provided with a buffer layer for reducing collision.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] As Figures 1-2As shown, the application provides a beam limiter aging detection device, which comprises a frame 1, a rotating disc 2 and an adapter 3. The frame 1 comprises a base 101 and a support 102, and the support 102 is fixedly arranged on the base 101. The rotating disc 2 is rotatably connected with the support 102 through a rotating shaft 201. The rotating shaft 201 has a rotation axis parallel to the horizontal plane. The adapter 3 is fixedly connected with the surface of the rotating disc 2 at a first side, and a beam limiter mounting position is arranged at a second side opposite to the first side.

[0025] In use, the beam limiter is first fixedly mounted on the beam limiter mounting position, which can be fixed by screws or buckles, and the specific manner is not limited here. Then, the rotating disc 2 is rotated by a preset angle and stopped, so that the aging detection of the beam limiter at a specific angle can be carried out. Since the rotating disc 2 can be rotated by any angle, the aging detection of the beam limiter at any angle can be realized. In addition, the aging detection of the beam limiter can also be carried out during the rotation of the rotating disc. Therefore, the beam limiter aging detection device of the application can simulate various stresses and environmental conditions that the beam limiter may encounter in actual use, and carry out comprehensive and detailed aging detection of the beam limiter, so that the beam limiter can be fully tested and run-in, and can be directly put into actual production.

[0026] In addition, as shown in Figure 2 , the support 102 can be protruded towards the rotating disc 2 to form a limiting part 121. The limiting part 121 is located below the rotating shaft 201, and the end face of the limiting part 121 is in contact with the surface of the rotating disc 2 to limit the rotating disc 2. In use, due to the gravity of the rotating disc 2, the end of the rotating shaft 201 close to the rotating disc 2 may have a sinking trend. At this time, the limiting part 121 can provide support for the lower part of the rotating disc 2 to prevent the rotating disc 2 from moving in the vertical plane, so that the center line of the rotating shaft 201 continues to remain in the horizontal plane. Therefore, the limiting part 121 helps to ensure that the beam limiter can carry out aging detection at the correct angle. In order to ensure that the rotating disc 2 can rotate normally, certain measures can be taken to reduce or eliminate the friction between the limiting part 121 and the rotating disc 2. Preferably, a ball can be arranged on the end face of the limiting part 121, and a lubricant can be applied on the ball as necessary to further reduce the friction.

[0027] In an embodiment, as shown in Figure 2 , the beam limiter aging detection device further comprises a stop device 4. The stop device 4 comprises a connecting part 401 fixedly connected with the support 102 and a stop part 402 movably connected with the connecting part 401. The stop device 4 comprises a locked state and an unlocked state. In the locked state, the stop part 402 is in contact with the edge of the rotating disc 2, so that the rotating disc 2 cannot rotate; in the unlocked state, the stop part 402 is separated from the edge of the rotating disc 2, and the rotating disc 2 can rotate normally.

[0028] In use, the stopper 402 is operated to be out of contact with the edge of the rotating disc 2, i.e. to ensure that the stopper 4 is in the unlocked state, and then the rotating disc 2 is rotated by a preset angle. After that, the stopper 402 is operated again to be in contact with the edge of the rotating disc 2, at which time the stopper 4 enters the locked state and can prevent the rotating disc 2 from rotating accidentally. On the surface of the stopper 402 used to contact the rotating disc 2, one or more of rubber, silicone, composite materials, etc. can be used for covering, so as to increase the friction and reduce the impact. The specific material is not limited here.

[0029] In an embodiment, as shown in Figures 1-3 The aging detection device for the beam limiter includes at least two adapters 3, which are symmetrically distributed relative to the center of the rotating disc. The adapters 3 can be distributed radially along the rotating disc 2, so that the beam limiters installed on all the adapters 3 have the same rotation angle. The surface of the rotating disc 2 can be pre-provided with a plurality of adapter installation positions, so that the operator can decide the number and position of the adapters 3 according to the actual needs and conveniently disassemble and assemble. This design can realize the aging detection of multiple beam limiters at the same time, thereby greatly improving the work efficiency. In addition, the symmetric distribution helps to evenly distribute the load of the rotating disc 2 and reduce the equipment wear or failure caused by uneven load.

[0030] In an embodiment, as shown in Figure 3 The aging detection device for the beam limiter includes a driver 5. The driver 5 is fixedly arranged on the support 102 and rotatably connected with the rotating shaft 201, and is used to drive the rotating shaft 201 to rotate around the center line thereof. The driver 5 can be one of a stepping motor or a servo motor, which is not limited here. Between the driver 5 and the support 102 and the rotating disc 2, a shock absorber, a shock pad or a flexible connection, etc. can be used to reduce the transmission of mechanical vibration, so that the rotation of the rotating disc 2 is more smooth and the negative impact on the beam limiter is reduced. In addition, a filter and a stabilizer can be used in the power supply and control circuit to reduce the influence of power fluctuation on the operation of the motor. The driver should also include necessary safety measures, such as overload protection, short circuit protection and overheat protection, to prevent equipment damage or safety accidents.

[0031] In an embodiment, as shown in Figure 3As shown, the aging test equipment for the clamp limiter includes a controller 6. The controller 6 is connected to the clamp limiter via a signal connection. The controller 6 has a built-in aging test program and a message monitoring program. In use, the driver 5 rotates the turntable 2 by a certain angle, and then the controller 6 sends a signal to the clamp limiter, causing it to start operating and perform aging tests according to the preset aging test program. After a predetermined time, the controller 6 sends another signal to the clamp limiter to stop operating, thus completing the aging test process of the clamp limiter at a specific angle. During the operation of the clamp limiter, the controller 6 can obtain and analyze the message information returned by the clamp limiter in real time through the message monitoring program, thereby realizing real-time monitoring of the clamp limiter's status and promptly issuing alarms in case of accidents, allowing operators to quickly grasp the status of the clamp limiter and take appropriate measures.

[0032] In one embodiment, such as Figure 3 As shown, controller 6 is signal-connected to driver 5. Controller 6 has a built-in turntable drive control program. During operation, controller 6 sends a signal to driver 5, causing driver 5 to rotate clockwise or counterclockwise by any preset angle and then stop. Simultaneously, controller 6 can incorporate precise control algorithms, such as PID (proportional-integral-derivative) control, to accurately adjust the speed of driver 5 and ensure smooth and gradual speed changes, avoiding shocks and vibrations caused by sudden acceleration or deceleration. In particular, it should implement soft-start (gradual acceleration) and soft-stop (gradual deceleration) functions to prevent unexpected displacement of moving parts inside the limiter due to sudden speed changes, thus avoiding affecting the accuracy and reliability of the aging detection process.

[0033] In one embodiment, an angle sensor (not shown in the figure) is provided on the turntable 2, and the angle sensor is signal-connected to the controller 6. When the limiter aging detection equipment is operating, the angle sensor monitors the rotation angle of the turntable 2 in real time, converts it into an electrical signal, and transmits it to the controller 6 so that the controller 6 can obtain the rotation state of the turntable 2 and calibrate the rotation angle of the turntable 2. The angle sensor can be a Hall effect angle sensor, a photoelectric angle sensor, or a magnetoresistive angle sensor; the specific type is not limited here. Furthermore, a scale mark can be provided on the edge of the turntable 2 to indicate the current angle of the adapter 3 relative to the center of the turntable 2. The scale mark allows the operator to determine the exact position of the adapter 3 on the turntable, which is of positive significance for ensuring the safe operation of the equipment.

[0034] In an embodiment, the second side of the adapter 3 is provided with a buffer layer for reducing impact. In the process of carrying out the aging detection, the components inside the beam limiter 7 will move, so from the outside perspective, the beam limiter 7 will inevitably vibrate, and the buffer layer can effectively alleviate the direct hard contact between the beam limiter 7 and the adapter 3, thereby reducing the risk of damage caused by vibration and impact. Preferably, the buffer layer can be made of high polymer materials such as rubber, silicone or polyimide, and the specific material is not limited here.

[0035] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
