[0030] Currently, the performance detection of the ray generation module in a ray generation device is usually carried out after assembling it into the ray generation device and then performing a whole-machine test, and the stability of the whole machine is determined by the performance of the emitted X-rays. During the detection, if it is determined that there is a fault in the ray generation device, it is very difficult for the device manufacturer or user to directly identify the cause of the fault at this time. Technicians need to go to the site to disassemble and assemble the device and parts to conduct repeated inspections and detections one by one, which makes this process very complex and inconvenient. Therefore, it is very necessary to detect the performance of the ray generation module before assembly to improve the yield rate of the ray tube.

[0031] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0032] Figure 1 It is a structural block diagram of a detection device for a ray generation module provided by an embodiment of this application. As Figure 1 shown, the detection device for a ray generation module provided by the embodiment of this application can very conveniently detect and analyze the ray generation module before the ray generation module is assembled into a complete machine. The detection device includes a mounting position 10, a detection unit 20, a control unit 30, and a display screen 40.

[0033] In this embodiment, the detection device includes at least one mounting position 10, and the mounting position 10 is used to mount the ray generation module to be tested, that is, the detection device can realize the performance detection of multiple ray generation modules to be tested at the same time, which can improve the detection efficiency. Correspondingly, there are also multiple detection units 20, which correspond one by one to the mounting positions, and are used to detect the performance of the ray generation module to be tested on the corresponding mounting positions.

[0034] Each detection unit 20 includes an ionization chamber 201 and a collection module 202. Among them, a receiving window is opened on the ionization chamber 201, and the receiving window faces the mounting position corresponding to its own detection unit, and is used to receive the X-rays emitted by the ray generation module to be tested. The ionization chamber 201 is fixedly installed on the detection device, and contains inert gas inside. After the gas passes through the X-ray current, a weak current is generated to form an electrical signal. The collection module 202 is connected to the ionization chamber and is used to collect the electrical signal formed in the ionization chamber, realizing the conversion from optical signal to electrical signal.

[0035] In some embodiments, the collection module 202 is built into the ionization chamber 101 to ensure accurate electrical signals are collected.

[0036] Since the current signal generated after the current is generally a weak current, in some embodiments, the collection module includes a pre-amplification board and a high-speed acquisition board connected in sequence. After receiving the weak electrical signal, the weak current signal is first amplified by the pre-amplification board, and then real-time acquisition is performed by the high-speed acquisition board.

[0037] It can be understood that precisely because the pre-amplification board has the advantages of enhancing signals and reducing noise, before collecting the electrical signals, the pre-amplification board can significantly enhance the amplitude of weak signals, making the electrical signals easier to detect and identify in subsequent processing. While amplifying the electrical signals, it can also reduce the influence of noise, significantly improving the signal-to-noise ratio (SNR) of the signals, thereby improving and ensuring the accuracy and reliability of the signals. The pre-amplification board usually has a variety of configuration options, can be customized according to the needs of specific applications, can adapt to various different signal types and processing requirements, and the pre-amplification board usually adopts a highly integrated design, integrating multiple functional modules on one board, which not only improves the compactness of the system but also reduces power consumption and costs. At the same time, since the pre-amplification board is an independent module, it is also convenient to be replaced with a new or upgraded version later, making the upgrade and maintenance relatively simple and fast.

[0038] Similarly, the high-speed acquisition board can capture a large amount of data in real time, has high resolution and precise measurement capabilities, can capture tiny signal changes, and is very useful in applications that require precise measurement. It transmits the acquired data to the control unit in real time to ensure the timeliness and accuracy of the data, and can still maintain stable performance under long-term operation and high load conditions. At the same time, the high-speed acquisition board has flexible interfaces and configurability, which is convenient to select and configure according to the actual situation and is more universal.

[0039] The control unit 30 is respectively connected to the acquisition modules of each detection unit. The control unit 30 is used to receive the electrical signals collected by all the acquisition modules, perform statistical analysis on them, generate and output the detection results, and the detection results can intuitively reflect the performance parameters of the ray generation module to be measured, such as the performance parameters of X-rays.

[0040] In some embodiments, the control unit 30 further includes a connection interface connected to the ray generation module to be measured. The control unit receives the performance parameters of the ray generation module to be measured through the connection interface, such as the performance parameters of the ray tube and the high-voltage power supply in the ray generation module to be measured, and the performance parameters include tube voltage, tube current, filament current, and / or the AD value of the ray. Specifically, the connection interface of the control unit 30 can be a quick connector, which is electrically connected to the circuit board in the ray generation module to be measured through the quick connector to obtain the performance parameters of the ray tube and the high-voltage power supply. Compared with the traditional wiring method, the quick connector only needs to insert the connection wire to complete the connection, and the operation is simple and convenient. The common quick connector has a self-locking function, which can ensure the stability and reliability of the electrical connection and can also prevent the plug from accidentally falling off during use.

[0041] In some embodiments, the control unit includes a data processing module 301, which is configured to summarize, analyze, and process the received electrical signals and performance parameters to generate a detection result. In a specific embodiment, the data processing module first preprocesses the received electrical signals and / or performance parameters characterizing the performance of the ray generation module to be tested, including median filtering the electrical signals and averaging the performance parameters, etc., to obtain more accurate analysis data. Then, the analysis data is summarized, analyzed, and processed. When necessary, plotting and simulation analysis can also be performed, and compared with the preset performance parameters to obtain a detection result. For example, error (glitch) analysis is performed on the analysis data. When the error (glitch) exceeds the preset threshold, it can be determined that one or more performance parameters of the ray generation module to be tested do not conform to the characterization, and the ray generation module to be tested is considered unqualified.

[0042] The display screen 40 is connected to the control unit 30 and can display the detection result in a preset display form after obtaining the detection result transmitted by the control unit. In some embodiments, the preset display form includes a display board and / or a visualization chart.

[0043] In summary, the detection device for the ray generation module provided by the embodiments of the present application has a simple structure, can conveniently detect and analyze the ray generation module before assembling the whole machine, can simultaneously detect the performance indicators of multiple ray generation modules, has an efficient and convenient detection program, and has a high detection accuracy, improving the yield rate of the ray tube and the high-voltage power supply, and thus effectively improving the detection qualification rate of the ray generation device.

[0044] Figure 2 This is a schematic structural diagram of a detection device for a ray generation module provided by another embodiment of the present application. As Figure 2 (a) shows, in this embodiment, the detection device for the ray generation module includes 6 installation positions 10 for installing the ray generation module to be tested. At least the ray tube a and the high-voltage power supply b in the ray generation module to be tested need to be installed on each installation position. The detection unit 20 is arranged below the installation position, and the control unit 30 is located below the detection unit to receive the detection data.

[0045] As Figure 2As shown in (a), a fixing module 50 is provided at each installation position. The fixing module is used to fix the ray generating module to be tested. The fixing module can be a fixture, and it can be fixed to the detection device with screws around it. Then, the ray tube a in the ray generating module to be tested is fixed therein, which can prevent interference caused by external vibration. Since the ionization chamber is arranged below the detection unit, an opening is provided below the fixing module, and the direction of the opening is directly opposite to the receiving window on the ionization chamber 201, so as to ensure that the ionization chamber can completely receive the X-rays emitted by the ray tube a on the fixing module, that is, the lower part of the fixing module determines the emission direction of the rays generated by the ray generating module. The distance between the window below the fixing module and the receiving window on the ionization chamber 201 can be calculated according to the actual situation, such as the acquisition accuracy of the acquisition module. Generally, the fixing module is made of aluminum metal material, which can effectively block radiation and play a protective role.

[0046] As shown in Figure 2 (b), in this embodiment, the detection device of the ray generating module further includes a shielding cover 60. The fixing module and the ionization chamber are both located inside the shielding cover. After installing the ray generating module to be tested, the shielding cover 60 is covered outside the fixing module and the ionization chamber. During the detection process, a little radiation overflowing between the fixing module and the ionization chamber can be shielded, so as to improve the radiation safety of the detection device and ensure the safety of the detection personnel.

[0047] The embodiment of the present application also provides a ray generating device, which includes a ray generating module and a detection device for the ray generating module as described in any of the above embodiments. Before using the ray generating device, the ray generating module therein can be installed in the detection device for detection, which can ensure that the performance of the ray generating module is intact before use, and can also find or eliminate whether the fault is caused by the ray generating module through the detection device when the ray generating device fails.

However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can make several simple deductions, deformations or substitutions without departing from the purpose of the present application and the scope protected by the claims. All of these belong to the protection scope of the present application.
