Abstract
Description
Technical Field
[0001] This utility model relates to the field of detector testing technology, specifically to a detector performance testing machine. Background Technology
[0002] During routine detector production and testing, the light emitted by the X-ray tube may differ from the actual application scenario of the detector, leading to test results that do not accurately reflect the detector's performance. Because the processing and control of X-ray tube light is relatively simple, there is a lack of refined management of light quality. In such cases, excessively strong light, excessive scattered light, or other optical problems may occur, affecting the detector's test results and resulting in inaccurate test data or unclear images. For example, when the light emitted by the X-ray tube is of high intensity, especially under high voltage and high current conditions, this high-intensity light may cause the detector to be overexposed, meaning that the number of photons received by the detector's pixel units exceeds its dynamic range, making accurate measurement impossible. In some cases, the emission intensity of the X-ray tube may not meet the detector's minimum sensitivity requirements, causing the detector to fail to respond effectively, thus affecting the accuracy and reliability of the test results.
[0003] These problems reduce the accuracy and reliability of testing, limiting the development and application of detector testing technology. Therefore, there is an urgent need for an innovative solution that can optimize light quality and improve testing accuracy and efficiency. Utility Model Content

[0041] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0042] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Although the illustrations only show components related to this utility model and are not drawn according to the actual number, shape and size of the components, the shape, quantity, positional relationship and proportion of each component can be arbitrarily changed under the premise of realizing the technical solution of this utility model, and the layout of the components may also be more complex.
[0043] This embodiment provides a detector performance testing machine, with reference to... Figures 1 to 4 The detector performance testing machine in this embodiment includes a frame body 1, an X-ray tube 111, a beam 112, a base plate 7, a testing platform 71, and a turntable 2.
[0044] Reference Figures 1 to 4The frame body 1 includes a top 11 and a bottom 12 disposed opposite to each other. An X-ray tube 111 is disposed on the top 11 of the frame body 1. A beam 112 is disposed on the top 11 of the frame body 1 and located directly below the X-ray tube 111, with an emission port 1121 at its bottom. A base plate 7 is located on the bottom 12 of the frame body 1. A detection platform 71 is located on the base plate 7 and is disposed opposite to the beam 112, with the projection of the emission port 1121 located on the detection platform 71. The detection platform 71 includes at least two limiting blocks 711, respectively disposed on adjacent sides of the detection platform 71. In an optional embodiment of this example, the detection platform 71 includes two limiting blocks 711, namely a front positioning limiting block and a left positioning limiting block. The position of the limiting blocks 711 can be adjusted according to the size of the detector. In this embodiment, the limiting blocks 711 can physically constrain the detector placed on the detection platform 71, preventing the detector from shifting due to external forces, such as vibration, during the testing process. By limiting the movement range of the detector, the limiting block 711 can prevent the detector from colliding with other components of the testing platform 71, thereby protecting the detector from damage. The side of the testing platform 71 opposite the X-ray tube 111 also includes multiple spiral groove markings 712. These spiral groove markings 712 serve as clear visual markers, helping operators quickly identify the placement position of the detector and improving operational efficiency. Simultaneously, the spiral groove markings 712 can serve as alignment references, ensuring that the detector is accurately aligned to the predetermined position during placement, reducing alignment time. Optionally, the spiral groove markings 712 can be designed with standardized dimensions, making them compatible with various detector models and improving the versatility of the testing platform 71. When adding new detector models in the future, as long as the detector's size and shape match the spiral groove markings 712, the existing testing platform 71 can be used directly without large-scale modifications. In this embodiment, the setting of the limiting block 711 and the spiral groove markings 712 on the testing platform 71, through the dual effects of physical constraint and visual guidance, jointly improves the positioning accuracy, operational efficiency, testing stability, and safety of the testing process. This design is not only suitable for current testing needs, but also has good scalability and versatility, and can adapt to possible future changes and upgrades.
[0045] Reference Figures 1 to 4The turntable 2 is rotatably mounted on the side of the beam strainer 112 opposite to the base plate 7. The turntable 2 has multiple stations 21, each equipped with a beam strainer fixture 211. Each beam strainer fixture 211 has an opening 2111. By rotating the turntable 2, the opening 2111 of each beam strainer fixture 211 can be aligned with the emission port 1121 at the bottom of the beam strainer 112. The emission port 1121 is a key component of the beam strainer 112, used to emit the light beam required for testing the detector. The beam strainer fixture 211 can intercept and adjust the light emitted from the X-ray tube 111. The beam strainer fixture 211 is made of at least 4mm, 21mm, 25mm, and 40mm aluminum. During testing, different beam strainer fixtures 211 can be switched according to different needs. When the light is too strong, the beam strainer fixture 211 can absorb or block some of the light, preventing excessively strong light from directly hitting the detector, thus avoiding inaccurate measurements due to overexposure. The beam fixture 211 can control the intensity of the light according to testing requirements. By optimizing the light quality, testing errors caused by light problems can be reduced. Multiple stations 21 are set on the turntable 2, and the beam fixture 211 on each station 21 can be customized according to different testing needs. When the turntable 2 rotates, the opening 2111 on each beam fixture 211 can be aligned with the emission port 1121 at the bottom of the beam emitter 1121 through precise mechanical movement. This alignment mechanism ensures that the light beam can accurately pass through the opening 2111 of the beam fixture 211 and then illuminate the detector on the testing platform 71. Furthermore, by controlling the rotation of the turntable 2, different beam fixtures 211 can be quickly switched to adapt to different testing requirements. Preferably, the detector performance testing machine also includes a control system (not shown in the figure), which is communicatively connected to the turntable 2 to control its rotation. The control system includes a host computer control system. For example, the turntable 2 is communicatively connected to the host computer control system. When testing different types or specifications of detectors, it is only necessary to turn on the switch controlling the rotation of the turntable 2 on the host computer and adjust it through the host computer's adjustment system until the corresponding beam fixture 211 is aligned with the emission port 1121. This rapid switching capability greatly reduces test preparation time and operational complexity, improving the efficiency of the entire testing process. Furthermore, this design has strong scalability and versatility. If new testing functions need to be added in the future or to adapt to new detector models, only a corresponding beam fixture 211 needs to be designed and installed on the turntable 2. Of course, the control system can also be located inside the detector performance testing machine; this is not an undue limitation.
[0046] Specifically, refer to Figures 1 to 4The detector performance testing platform also includes an upper mounting plate 3, an X-ray tube support base 31, an X-ray tube mounting frame 311, and an X-ray tube support 3111.

The X-ray tube support 3111 is disposed between the X-ray tube mounting frame 311 and the beam 112 to connect the X-ray tube mounting frame 311 and the beam 112. In an optional embodiment of this example, the rotation of the turntable 2 is achieved by providing a synchronous pulley 33, a gear set 4, and a belt 5. Specifically, the synchronous pulley 33 is rotatably mounted on the upper mounting plate 3, and a pulley mounting seat 331 is provided between the synchronous pulley 33 and the upper mounting plate 3 to connect the synchronous pulley 33 and the upper mounting plate 3.

Turning on the switch controlling the pulley motor controls the rotation of the synchronous pulley 33. The gear set 4 includes a gear 41 and a rotating shaft 42. The rotating shaft 42 passes through the upper mounting plate 3 and is fixedly connected to the center position of the turntable 2. The gear 41 is located above the upper mounting plate 3 and is fixedly connected to the rotating shaft 42. The belt 5 is sleeved on the synchronous pulley 33 and the gear set 4 to drive the gear set 4 to rotate when the synchronous pulley 33 rotates, thereby driving the turntable 2 to rotate. Of course, the way to achieve the rotation of the turntable 2 is not limited to this, and other methods can also be used to achieve the rotation of the turntable 2.

One end of each slider 131 is connected to the auxiliary connecting plate 32, and the other end is movably fitted onto the linear rail 13. The up and down movement of the slider 131 on the linear rail allows for the up and down movement of the X-ray tube 111, the beam 112, and the turntable, thereby enabling adjustment of the SID. Specifically, in an optional embodiment of this embodiment, the detector performance testing machine further includes four auxiliary connecting plates 32, four linear rails 13, and four sliders 131. Two auxiliary connecting plates 32 are positioned along the Y-axis at one end of the upper mounting plate 3, and two other auxiliary connecting plates 32 are positioned along the Y-axis at the other end of the upper mounting plate 3. Four linear guides 13 are respectively positioned corresponding to the four auxiliary connecting plates 32. Each linear guide 13 is connected to its corresponding auxiliary connecting plate 32 via a slider 131. One end of the slider 131 is connected to the auxiliary connecting plate 32, and the other end is movably fitted onto the linear guide 13. The detector performance testing machine also includes a lifting motor 6, which is located on the top 11 of the frame body 1 and connected to the X-ray tube 111 to drive the X-ray tube 111 to move up and down.
