[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] The present embodiment provides an X-ray monitoring method for a bone age meter, which can be run in a main control module of the bone age meter. The method obtains multi-channel X-ray radiation intensity data obtained by detecting an X-ray source through radiation sensors in multiple directions in the main body of the bone age meter. The radiation sensors in multiple directions surround the X-ray source to form a 360° detector network. The multi-channel X-ray radiation intensity data are fused and calculated through a fusion algorithm to obtain the overall radiation state of the X-ray source. The overall radiation state of the X-ray source is classified and safety evaluated through a trained AI radiation analysis model. According to the evaluation result of the AI ​​radiation analysis model, the user is prompted in real time about the current X-ray radiation safety state of the X-ray source, thereby realizing accurate detection of X-ray radiation of the X-ray source, discovering X-ray radiation safety hazards in real time, and improving user experience.

[0029] See also Figure 1-Figure 7 The X-ray monitoring method of the bone age meter provided in this embodiment includes the following steps:

[0030] S101, acquiring multi-path X-ray radiation intensity data obtained by radiation sensors in multiple directions in the body 1 of the bone age meter detecting an X-ray source 104, wherein the radiation sensors in multiple directions surround the X-ray source to form a 360° detector network;

[0031] S102, performing fusion calculation on the multi-channel X-ray radiation intensity data by using a fusion algorithm to obtain the overall radiation state of the X-ray source;

[0032] S103. Classify and conduct safety assessment on the overall radiation status of the X-ray source using a trained AI radiation analysis model, and prompt the user in real time about the current X-ray radiation safety status of the X-ray source based on the assessment result of the AI ​​radiation analysis model.

[0033] It should be noted that in step S101, by arranging radiation sensors in multiple directions in the fuselage to form a 360° covered detector network, the radiation leakage risk of the X-ray source can be fully monitored to make up for the blind spots that may exist in single-point detection. As the use time of the bone age meter increases, the shielding material may age or be damaged, increasing the possibility of unexpected leakage. The multi-point layout can detect local radiation exceeding the standard caused by shielding defects and provide data support for maintenance or improved design. In addition, the collection of multi-directional data can reduce the impact of measurement errors of a single detector. When there is an abnormality in a specific direction, detectors in other directions can play a comparative verification role to improve the credibility of the measurement results. In step S102, considering that X-ray radiation has directional and attenuation characteristics, the radiation intensity data in different directions can be comprehensively analyzed through the fusion algorithm to generate a more accurate overall radiation state. The fusion algorithm takes into account the correlation between spatial position and detector data, and can integrate the measurement data in each direction into a radiation field distribution map, clearly showing the spatial distribution of radiation intensity, facilitating the location of leakage hotspots, and avoiding misjudgment or missed judgment. In addition, through fast fusion calculation, real-time radiation status updates can be achieved, providing efficient input for subsequent AI analysis. In step S103, the overall radiation status of the fused X-ray source is classified (such as safe, warning, and dangerous) through the trained AI radiation analysis model, which can provide accurate radiation safety assessments and avoid false alarms or omissions that may exist in traditional methods due to simple rules. The AI ​​radiation analysis model can capture subtle anomalies in the state of radiation sources or shielding materials based on the dynamic changes of radiation data, and give assessment results in a timely manner to prevent potential risks from expanding. In addition, the safety assessment of the AI ​​radiation analysis model can provide users with clear safety prompts, for example, safety: normal use, no intervention required. For example, warning: it is recommended to shorten the operation time or check the shielding status. For example, danger: stop using immediately and contact maintenance personnel.

[0034] In some preferred embodiments, when the multi-channel X-ray radiation intensity data is fused and calculated by a fusion algorithm, it includes: normalizing the multi-channel X-ray radiation intensity data collected by radiation sensors in various directions to eliminate the influence of sensitivity differences of different sensors; allocating weights according to the spatial positions and directional characteristics of the radiation sensors in various directions, and the weights are set according to the inverse relationship between the distances between the radiation sensors and the X-ray sources; and calculating the overall radiation state of the X-ray source according to the weights and the normalized values ​​of the multi-channel X-ray radiation intensity data.

[0035] In some preferred embodiments, the value of the multi-channel X-ray radiation intensity data after normalization is assumed to be D′ i , D′ i The range of is [0,1], then the normalization algorithm is:

[0036]

[0037] Among them, D i is the original radiation intensity value of the i-th sensor, D min and D max are the minimum and maximum values ​​of all sensor data respectively.

[0038] In some preferred embodiments, let the weight be w i , the overall radiation state of the X-ray source is S, then the algorithm for calculating the overall radiation state of the X-ray source is:

[0039]

[0040] Wherein, N is the total number of radiation sensors.

[0041] It should be noted that, in the above embodiments, the normalized value D′ is obtained by normalizing the multi-channel X-ray radiation intensity data collected by the radiation sensors in each direction. i , and then assign weights w according to the spatial position and directional characteristics of the radiation sensors in each direction i , weight w i According to the inverse relationship between the radiation sensor and the X-ray source, the weight w i and the multi-channel X-ray radiation intensity data is normalized to obtain the value D′ i , calculate the overall radiation status of the X-ray source, meet the bone age detection scenario with high real-time requirements, calculate quickly, and reduce the impact of single-point abnormal data.

[0042] In some preferred embodiments, the AI ​​radiation analysis model adopts a convolutional neural network model, and the convolutional neural network model is trained to obtain the trained AI radiation analysis model; when training the convolutional neural network model, it includes: collecting radiation intensity data from multi-directional radiation sensors and marking safety status labels to obtain labeled multi-channel X-ray radiation intensity data; training the convolutional neural network model through labeled multi-channel X-ray radiation intensity data to obtain the trained AI radiation analysis model. It should be noted that sensor data from different directions contain rich spatial information, which helps CNN to extract multi-dimensional features and improve the model's ability to recognize complex radiation distributions. Especially in special cases such as radiation leakage or aging of shielding materials, multi-directional data can provide a comprehensive evaluation basis. Preferably, the safety status labels annotated on the radiation intensity data include safety labels, warning labels, and danger labels. Among them, labeled data can be used to capture pattern differences between different categories, which helps the convolutional neural network model detect tiny radiation anomalies. It should be noted that through training, the convolutional neural network model can associate multi-directional radiation intensity data with safety status categories, thereby automatically identifying implicit features in the radiation intensity distribution. The distribution of radiation intensity has complex nonlinear relationships, and the convolutional neural network model can model these nonlinear relationships through multi-layer feature extraction and nonlinear activation functions.

[0043] In some preferred embodiments, based on the evaluation result of the AI ​​radiation analysis model, the user is prompted in real time about the X-ray radiation safety status of the current X-ray source, including: when the evaluation result of the AI ​​radiation analysis model is X-ray radiation safety, the display screen of the bone age meter is controlled to display a prompt for normal use. It should be noted that in this embodiment, by providing real-time prompts for normal use, the user can intuitively understand that the current radiation status of the device is safe, avoid misoperation or unnecessary concerns caused by unclear status, and ensure the safety and efficiency of the use of the device.

[0044] In some preferred embodiments, based on the evaluation result of the AI ​​radiation analysis model, the user is prompted in real time about the X-ray radiation safety status of the current X-ray source, including: when the evaluation result of the AI ​​radiation analysis model is an X-ray radiation warning, the display screen of the bone age meter is controlled to display a prompt suggesting to shorten the operation time or check the shielding status. It should be noted that in this embodiment, when the X-ray radiation evaluation result is a warning, the user is prompted to shorten the operation time or check the shielding status, which can timely warn of potential radiation risks exceeding the standard and prevent radiation hazards caused by long-term exposure or abnormal equipment shielding. In addition, through clear operational suggestions (such as shortening the operation time or checking the shielding), users can be helped to respond quickly and appropriately, reduce equipment outages or unnecessary interventions, improve the safety and efficiency of equipment use, and reduce the possibility of risk expansion.

[0045] In some preferred embodiments, based on the evaluation result of the AI ​​radiation analysis model, the user is prompted in real time about the X-ray radiation safety status of the current X-ray source, including: when the evaluation result of the AI ​​radiation analysis model is an X-ray radiation hazard, the display screen of the bone age meter is controlled to display a prompt to stop using it immediately and contact maintenance personnel. It should be noted that in this embodiment, when the evaluation result is dangerous, by prompting the user to stop using it immediately, continuous exposure in a high-radiation environment can be effectively avoided, thereby protecting the health and safety of the user.

[0046] In some further embodiments, an X-ray detection box module 10 is arranged in the main body of the bone age meter, and the X-ray detection box module 10 includes a shielding chassis 102, a digital detector 103, an X-ray source 104, a wiring harness device 105 and a ray source bracket 106; the detection port 100 is located at the upper end of the shielding chassis 102, connected to the detection channel 101 located inside the upper end of the shielding chassis 102, the digital detector 103 is installed above the detection channel 101, and the X-ray source 104, the wiring harness device 105 and the ray source bracket 106 are all installed inside the bottom end of the shielding chassis 102; the X-ray source 104 is installed On the ray source bracket 106, the wire beam device 105 is installed at the upper end of the X-ray source 104; the radiation sensors in multiple directions are arranged on the outer side of the side wall outside the upper and lower ends of the shielding chassis 102, surrounding the X-ray source to form a 360° detector network; the digital detector 103 detects the X-rays penetrating the user's hand in the detection channel, and converts the X-rays into digital images reflecting the X-ray hand images of the user's hand. The main control module 2 is connected to the digital detector 103 for communication, and the main control module 2 obtains the digital image, performs image display processing on the digital image, so as to generate a digital image display signal for display through the display screen 4 of the bone age meter.

[0047] It should be noted that the shielded chassis 102 can be used to block X-rays from leaking outside the detection channel 101, protecting users and operators from radiation damage. Specifically, the shielded chassis 102 can be made of high-density materials (such as lead or special alloys). The digital detector 103 is located above the detection channel 101 and directly receives the X-ray signal that penetrates the hand, which can maximize the clarity and resolution of the image. Moreover, the image data structure provided by the vertical detection path is simple, which can reduce the complexity of the image processing algorithm. The digital detector 103 converts the X-rays that penetrate the hand into high-resolution digital images and transmits them to the main control module 2 for processing. In addition, the X-ray source 104 is installed inside the bottom of the shielded chassis 102 to ensure that the ray emission path is stable and accurate, and to reduce external vibration or environmental influences. The rays are emitted from the bottom and vertically pass through the detection channel 101 to the digital detector 103. The imaging path is short and refraction-free, which improves the image quality. The X-ray source 104 is covered by the bottom of the chassis, which can minimize the risk of ray leakage and accidental exposure. The wire harness device 105 is used to limit the X-ray beam shape to a specific width or shape, ensuring that the rays are concentrated on the hand area to avoid radiation waste or diffusion. The ray source bracket 106 firmly mounts the X-ray source 104 inside the bottom of the chassis to prevent the ray emission path from being offset due to vibration or changes in the use environment. The detection port 100 is located at the upper end of the shielded chassis 102, and the detection channel 101 is connected to the inside of the chassis, which is convenient for the user to directly put the hand into the channel for detection. It should be noted that although the shielded chassis 102 is designed with high-density materials, the shielding material may age, be damaged or partially weakened with the long-term use of the equipment. The radiation sensor can detect whether there are leaks in the shielded chassis to ensure that the X-ray source is effectively shielded. If there are defects or manufacturing process problems in the shielded chassis, the sensor network can be used to detect the existing defects in real time, reminding the user to maintain or stop using the equipment. It should also be noted that the X-rays are emitted from the bottom of the chassis, pass through the detection channel 101, and are received and imaged by the digital detector 103 at the top of the chassis. Placing the sensor on the outside of the side wall outside the upper and lower ends can avoid the main ray path and ensure that the quality and imaging accuracy of the X-ray image are not disturbed.

[0048] In some further embodiments, before the fusion calculation of the multi-channel X-ray radiation intensity data, the X-ray radiation intensity data of each channel in the multi-channel X-ray radiation intensity data is compared with the radiation danger threshold. When the X-ray radiation intensity data of a channel in the multi-channel X-ray radiation intensity data exceeds the radiation danger threshold, the fusion calculation of the multi-channel X-ray radiation intensity data is skipped, and the user is directly prompted that the X-ray radiation of the current X-ray source is in a dangerous state, and the user is advised to stop detecting bone age and stay away from the X-ray source. It should be noted that in the multi-channel radiation data, if the radiation intensity of a channel exceeds the danger threshold, it means that there may be serious radiation leakage in this direction. In this case, skipping the complex fusion calculation and directly prompting the dangerous state can timely remind the user to stop using and stay away from the X-ray source, and maximize the protection of the health and safety of users and operators. Once it is found that a single channel of data exceeds the danger threshold, it is faster to directly judge the dangerous state than to perform fusion calculation. Fusion calculation involves the integration of multi-directional data, weight allocation and algorithm execution, which requires additional time. In the case of clear danger, there is no need to perform fusion calculation on the data in other directions. Fusion calculation requires the combination of multi-channel sensor data to perform complex algorithm operations. Skipping fusion calculation can significantly save the system's computing resources, leaving more computing resources for the bone age meter to handle various tasks such as image generation, thereby reducing the computing burden of the bone age meter.

During detection, the user's hand extends from the radiation-proof sleeve 116 into the detection port 100 and the detection channel 101, thereby preventing X-ray leakage and protecting the user and the operating doctor. Furthermore, an expansion table for installing a printer is also provided on one side of the fuselage shell 11. The printer is installed on the surface of the expansion table 117, which can fully utilize the function of the expansion table 117. The operating doctor does not need to configure additional printing equipment. The expansion table 117 provides an independent space for printing work, and the layout is more reasonable. Furthermore, the expansion table 117 can be set as a foldable expansion table 117. When the printer is not needed, the foldable expansion table 117 is folded and stored on one side of the fuselage shell 11, thereby reducing the space occupied by the equipment and facilitating the movement of the equipment.
