TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, specifically, relate to a kind of beam limiter and X ray machine. BACKGROUND

[0002] The beam limiter is a device used to limit the radiation range of an X-ray tube in medical X-ray diagnostic equipment. It is installed on the window of the X-ray tube assembly and used to block unnecessary primary X-rays during X-ray examination, thereby ensuring the safety of the examinee and preventing X-ray radiation from polluting the surrounding environment. However, during the use of traditional beam limiters, the display and adjustment of parameters have become a significant pain point. Specifically, during use, the operating physician will adjust the parameters of the beam limiter according to the actual situation. However, the parameters of the traditional beam limiter are only displayed on the DR (Digital Radiography) system end (the terminal or operating interface of the direct digital X-ray photography system), and the operating physician needs to switch back and forth between the beam limiter and the system to confirm the parameters. This operating method not only increases the complexity of the operation, but also may cause time waste and operation errors. Especially in emergency situations, the physician needs to quickly and accurately adjust the beam limiter parameters, and frequent switching of the operating interface may affect the efficiency and accuracy of the diagnosis. In addition, the parameter display of the traditional beam limiter is not intuitive enough, and the physician may need additional time to interpret the parameters, which further reduces the work efficiency.

Figure 3 As can be seen, in this embodiment, the information parameters displayed on the display screen 20 include: a limiter aperture size display 201, an additional filtration level display 202, and a SID display 203. Generally, the position of the operating parameter information displayed on the display screen 20 can be arbitrarily set. Specifically, in this embodiment, the limiter aperture size display 201 is located at the top of the display screen 20; the SID display 203 is located at the bottom of the display screen 20 and is centered; the additional filtration level display 202 is located below the limiter aperture size display 201 and above the SID display 203.

[0037] Generally, the functional components within the collimator body 10 include a lead sheet layer, which comprises a horizontal lead sheet layer and a vertical lead sheet layer. By adjusting the positions of the horizontal and vertical lead sheets, they cooperate to form an opening, which is the lead window. The X-ray irradiation range is further controlled by controlling the size of the lead window opening. Specifically, in this embodiment, the collimator opening size display 201 is located at the top of the display screen 20, allowing the operator to more intuitively and clearly confirm the collimator opening size. The operator can adjust the knob on the collimator body to adjust the lead window opening size, which will then be displayed on the display screen 20. This eliminates the need to switch back and forth between the collimator and the entire system to confirm parameters, greatly improving the operator's work efficiency.

[0038] Generally, the functional components in the collimator body 10 also include additional filtration, which is a filter plate or other substance added between the X-ray source and the detected person to absorb low-energy X-rays, thereby improving image quality and reducing the radiation dose received by the patient. Generally, the additional filtration can be aluminum or other materials such as copper. Specifically, in this embodiment, copper is taken as an example of the additional filtration material. By adjusting the additional filtration position, the energy spectrum of the X-ray is optimized, the problem of overexposure of soft tissue is reduced, and the contrast and clarity of the image are improved. Specifically, in this embodiment, the additional filtration position display 202 is arranged below the collimator opening size display 201, so that the operating physician can more quickly and accurately identify the additional filtration position 202, improve the accuracy of diagnosis, and further protect the safety of the detected person.

[0039] Specifically, the SID display 203 is located at the lowermost part of the display screen 20, so that the operating physician can conveniently identify the size of the SID, reduce the probability of diagnostic errors, and avoid unnecessary radiation to the detected person. The size of the SID will directly affect the size and shape of the X-ray radiation field and the quality of the image. Generally, the SID size of the X-ray collimator will be different according to different application requirements and equipment specifications. Generally, the SID size ranges from 65 cm to 200 cm. Further, the SID size ranges from 100 cm to 200 cm. Specifically, the SID display 203 of the collimator in this embodiment is fixed at 100 cm and 180 cm. However, it should be noted that the protection scope of the present application is not limited to the SID size of 100 cm and 180 cm.

[0040] The collimator provided in this embodiment can enable the operating physician to timely view the working parameter information displayed on the display screen 20 and quickly and accurately adjust the collimator, greatly simplifying the operation process and reducing the operation complexity. In addition, the addition of the display screen 20 makes the appearance of the collimator more neat.

Specifically, the collimator provided in this embodiment is based on the collimator provided in Embodiment One, and the display screen 60 is additionally provided with a control button, so that the operating physician can more quickly and accurately set the parameters. As shown in Figure 6 , it is a zoomed-in view of the display screen 60 of the collimator as shown in Figure 4 . As shown in Figure 6It can be seen that the information displayed and controlled by the display screen 60 includes: a collimator opening size display 601, an additional filtration position display 602, an additional filtration position switching button 603, a horizontal leaf adjustment button 604, a vertical leaf adjustment button 605, an indicator light button 606, a 180cm SID adjustment button 607, a 100cm SID adjustment button 608, and a commonly used opening shortcut button 609.

[0043] Specifically, the additional filtration position switching button 603 includes an additional filtration position up button and an additional filtration position down button. Specifically, the commonly used opening shortcut button 609 is provided in the embodiment, which is used to store the commonly used leaf opening size. The number of the commonly used opening shortcut button 609 can be designed according to the actual situation of the display screen 60. Specifically, in the embodiment, four commonly used opening shortcut buttons are provided. The indicator light 606 is used to provide lighting and indication, which helps the operator to better position and adjust the irradiation area of the X-ray machine. Generally, the indicator light 606 can be an LED lamp, an incandescent lamp, a fluorescent lamp, or other lamps. In the embodiment, the indicator light 606 is an LED lamp. The number of the SID adjustment button can be set according to the actual situation. Generally, the number of the SID adjustment button is greater than or equal to two. Generally, the SID adjustment button can be set as: a 65cm SID adjustment button, a 100cm SID adjustment button, and a 180cm SID adjustment button.

Specifically, the collimator opening size display 601 is located at the top of the display screen 60; the additional filtration position display 602 is located below the collimator opening size display 601; the additional filtration position up button and the additional filtration position down button are respectively arranged at both ends of the additional filtration position display 602; the indicator light button 606 is arranged directly below the additional filtration position switching button 603; the horizontal leaf adjustment button 604 and the vertical leaf adjustment button 605 are arranged at both ends of the indicator light button 606; the 180cm SID adjustment button 607 and the 100cm SID adjustment button 608 are arranged at the bottom of the display screen 60 and arranged on the left; and the commonly used opening shortcut button 609 is arranged at the bottom of the display screen 60 and arranged side by side with the 180cm SID adjustment button 607 and the 100cm SID adjustment button 608.

[0045] Generally, as shown in Figure 5 the schematic diagram of the front panel 30 of the collimator in the embodiment is displayed. As shown in Figure 5It can be seen that the front panel 30 of the collimator is provided with a transverse leaf adjustment knob 301 and a longitudinal leaf adjustment knob 302. Specifically, the transverse leaf adjustment button 604 and the longitudinal leaf adjustment button 605 are consistent with the functions of the transverse leaf adjustment knob 301 and the longitudinal leaf adjustment knob 302 on the collimator body 10. The difference is that the transverse leaf adjustment button 604 and the longitudinal leaf adjustment button 605 can allow the operator to control the opening and closing of the leaf by directly touching or clicking through the integration on the display screen 60, which can be more rapid and accurate; while the transverse leaf adjustment knob 301 and the longitudinal leaf adjustment knob 302 are a more traditional mechanical adjustment method, which requires the operator to rotate the knob to adjust the leaf position. However, in some cases, the knob adjustment is more rapid, so the collimator provided in this embodiment adopts the combination of knob adjustment and display screen adjustment to provide higher operation efficiency.

[0046] Generally, please continue to refer to Figure 2 The collimator provided in this embodiment also includes a screen adapter plate 40 and an adapter line 50. The collimator supplies power to the display screen 60 through the screen adapter plate 40, and realizes the communication connection between the collimator body 10 and the display screen 60 through the adapter line 50.

[0047] The collimator provided in this embodiment greatly improves the work efficiency and safety of the operator by adding the display screen 60. Specifically, the display screen 60 allows the operator to observe the opening size of the collimator in real time, and also allows the operator to directly control the opening size of the display on the screen, which can reduce the movement of the operator during operation, ensure the accuracy of the irradiation field, and improve the work efficiency. In addition, the transverse leaf adjustment button 604 and the longitudinal leaf adjustment button 605 are added, which cooperate with the leaf adjustment knob on the collimator body 10 to provide two different operation methods to adapt to the preferences of different operators and the needs of specific operation environment. This design improves the flexibility and convenience of operation, especially in emergency situations, the ability to quickly adjust the irradiation field is crucial for timely diagnosis and treatment. In addition, the addition of the frequently used opening convenient button 609 further improves the work efficiency of the operator. This button allows the operator to quickly select the commonly used irradiation field setting, reducing the time required for each adjustment, so that the operator can focus more on diagnosis and treatment itself rather than the operation of the equipment.

[0048] In general, the collimator of the system of this embodiment not only improves the work efficiency of the operator, but also enhances the operation experience of the operator by providing a more intuitive and faster operation interface, thereby indirectly improving the quality of medical services. At the same time, by accurately controlling the irradiation field, these improvements also help to reduce the radiation dose of the patient, improve the imaging quality, and further enhance the safety and effectiveness of the medical equipment
