Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary diagnosis device for medical images. Background Art

[0002] In today's medical field, medical imaging diagnosis has become an indispensable key link in the disease diagnosis and treatment process, covering a wide range of modalities such as X-ray, CT (computed tomography), MRI (magnetic resonance imaging), ultrasound, etc. However, the traditional medical imaging diagnosis work model has exposed many shortcomings when faced with massive imaging data, complex disease analysis, and the growing demand for diagnosis and treatment accuracy and efficiency.

[0003] On the one hand, traditional medical image observation lamps have significant limitations in the design of light coverage, and it is difficult to accurately adapt to the diverse medical image specifications and actual needs of film reading. In daily diagnosis and treatment scenarios, medical images cover a wide range, ranging from small-sized local close-up X-rays to large-format images showing the whole body skeleton or thorax. Conventional observation lamps mostly use fixed-size, single lighting area settings. When facing smaller-sized images, strong light is spread over a large area, which can easily cause light overflow, forming glare and reflective areas around, interfering with the doctor's vision, making it difficult to focus on the core details of the image. Furthermore, different imaging methods (such as X-rays, CT, MRI), examination sites (bones, lungs, abdominal organs) and lesion types (inflammation, tumors, calcification foci) have differentiated and strict requirements for the adaptability of observation light color temperature. However, traditional observation lamps often only provide a limited number of fixed color temperature options, and most of them even only maintain a single default color temperature, which is far from matching complex and changing diagnostic scenarios.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to the attached Figure 1 -Attached Figure 8 An embodiment of the present invention provides an auxiliary diagnosis device for medical images, including a support table 1, an observation table 2 is installed on the top of the support table 1, a clamping mechanism 3 is installed on the top of the observation table 2, which is used to fix the X-ray film, and evenly distributed observation lights 4 are installed on the top of the observation table 2, which are used to create a suitable X-ray film observation environment. One end of the clamping mechanism 3 is connected to a synchronization mechanism 5, which is used to synchronously change the illumination area of ​​the observation light 4. An auxiliary diagnosis system is also installed on the top of the support table 1, and the auxiliary diagnosis system is electrically connected to the observation light 4, which is used to adjust the color temperature of the observation light 4.

[0037] The clamping mechanism 3 includes a slide rail 301, which is provided on the top of the observation platform 2. A moving seat 302 is slidably connected inside the slide rail 301, and a clamping assembly 303 is installed on the top of the moving seat 302 for positioning the X-ray film.

[0038] The clamping assembly 303 includes a placing frame 304, which is fixedly connected to the top of the moving seat 302, one end of a short rod 305 is installed on one side of the inner wall of the placing frame 304, and the other end of the short rod 305 is installed with a rotating shaft 1 306, one side of the outer wall of a clamping plate 307 is installed inside the rotating shaft 1 306, and a rotating shaft 2 308 is installed on the other side of the outer wall of the clamping plate 307, and one end of a spring 309 is installed on the other side of the inner wall of the placing frame 304, and the other end of the spring 309 is connected to the rotating shaft 2 308;

[0039] One end of a rubber pad 311 is installed at the bottom of the card plate 307, and the other end of the rubber pad 311 extends to the bottom of the second rotating shaft 308;

[0040] A telescopic rod 310 is installed on the outer wall of the moving seat 302, and a plurality of moving seats 302 are connected by the telescopic rod 310;

[0041] Specifically, in the initial state, the card plate 307 is in an open position under the pulling force of the spring 309. When an X-ray film needs to be placed, the X-ray film is slowly pushed in along the direction of the placement frame 304. The placement frame 304, as the basic frame for carrying the X-ray film, provides a preliminary positioning guide for the X-ray film. Its size is adapted to the specifications of common X-ray films to ensure that the X-ray film can be placed flat. As the X-ray film touches the card plate 307, the X-ray film applies a force to the card plate 307, prompting the card plate 307 to start rotating with the rotating shaft 1 306 as the axis. At this time, the short rod 305 plays an auxiliary role in conduction and limiting, standardizing the rotation path and amplitude of the card plate 307 to prevent it from swinging excessively. The first rotating shaft 306 cooperates with the second rotating shaft 308 to enable the clamping plate 307 to open and close flexibly. When the X-ray film is fully pushed into the appropriate position in the placement frame 304, the spring 309, based on the restoring force generated by its own elastic deformation, pulls the second rotating shaft 308, driving the clamping plate 307 to clamp the X-ray film tightly. The rubber pad 311 at the bottom of the clamping plate 307 plays a key role in this process. On the one hand, the rubber pad 311 is soft and has good friction, which can not only avoid scratching and damage to the surface of the X-ray film, but also effectively protect the integrity of the X-ray film image information; it can also increase the friction between the X-ray film and the X-ray film, and strengthen the clamping stability. Even when the observation platform 2 is slightly vibrated due to operation, it can ensure that the X-ray film does not move at all. The moving seat 302 can slide smoothly in the slide rail 301, and the position can be flexibly adjusted according to the size of the X-ray film. Multiple mobile seats 302 are connected by means of a telescopic rod 310, and the telescopic rod 310 links multiple mobile seats 302. When one of the mobile seats 302 moves and adjusts, the telescopic rod 310 drives other mobile seats 302 to move synchronously, ensuring that the various locking components 303 work together, and can achieve accurate and uniform fixing effects for X-ray films of different specifications, meeting the needs of diverse clinical usage scenarios.

[0042] The synchronization mechanism 5 includes a fixed rod 501, one end of which is connected to one side of the outer wall of the movable seat 302, a sliding rheostat 503 is installed inside the observation platform 2, a sliding plate 502 is slidably connected to the outer wall of the sliding rheostat 503, the other end of the fixed rod 501 is connected to the sliding plate 502, and the terminal of the sliding rheostat 503 is electrically connected to the observation lamp 4;

[0043] Specifically, when the moving seat 302 slides on the slide rail 301, the fixed rod 501 acts as a linkage and moves synchronously with the moving seat 302. Since one end of the fixed rod 501 is rigidly connected to one side of the outer wall of the moving seat 302, and the other end is connected to the slider 502 of the sliding rheostat 503, the movement of the moving seat 302 will accurately pull the slider 502 to slide on the outer wall of the sliding rheostat 503. The sliding rheostat 503 is based on electrical principles, and the position change of the slider 502 will change the resistance value of the connected circuit. In terms of circuit connection design, the terminal of the sliding rheostat 503 is electrically connected to the observation light 4 to form a complete control loop. As the resistance value changes, the current intensity flowing through the observation light 4 is adjusted accordingly. According to Ohm's law (where I is the current intensity, U is the power supply voltage, and R is the resistance value). When the slider 502 increases the resistance, the current decreases, the brightness of the observation lamp 4 decreases, and the illumination range decreases; conversely, the resistance decreases, the current increases, the light becomes brighter, and the illumination range expands. In this way, it can cleverly match the actual placement position and size of the X-ray film, dynamically adjust the illumination area, and ensure that the key parts of the X-ray film are always covered by bright and uniform light, providing high-quality visual conditions for doctors to observe.

[0044] The support platform 1 includes a support base 101, a hydraulic rod 102 is installed at one end of the support base 101, a support plate 103 is fixedly connected to the output end of the hydraulic rod 102, a fixed plate 104 is installed at one end of the support plate 103, an electric push rod 105 is installed at the other end of the support plate 103, and a rotating shaft 3 106 is installed at one end of the fixed plate 104 and the electric push rod 105, and the rotating shaft 3 106 is connected to the observation platform 2;

[0045] Specifically, the sealed liquid in the hydraulic system of the hydraulic rod 102 is driven by the pump to adjust the pressure and flow according to the control command. When the adjustment command of the hydraulic rod 102 is started, the liquid pressure pushes the piston inside the hydraulic rod 102 to move, driving the support plate 103 to rise and fall smoothly in the vertical direction, adapting to the operation height preferences of doctors of different heights, and reducing various uncomfortable movements including bending. The electric push rod 105 is combined with the rotating shaft 3 106 to perform the angle adjustment function. After the electric push rod 105 receives the angle adjustment electrical signal, the push rod is extended and retracted to change the length, and a rotation torque is applied to the observation platform 2 by cooperating with the rotating shaft 3 106. Based on the principle of lever and the principle of rotation balance, with the rotating shaft 3 106 as the fulcrum, the extension force of the electric push rod 105 is converted into the rotation power of the observation platform 2 around the rotating shaft 3 106, so as to realize the flexible change of the tilt angle, facilitate the doctor to switch the observation angles such as the horizontal and downward view, accurately analyze the image characteristics of the X-ray film, especially for the images of special parts such as the spine and pelvis, multi-angle examination helps to capture subtle lesion information, and reduce the risk of misdiagnosis and missed diagnosis.

[0046] The auxiliary diagnosis system includes:

[0047] Algorithm trigger module: uses the camera to collect and analyze the image and feature data of the X-ray film. The feature data deviates from the set threshold to trigger the color temperature decision;

[0048] Color temperature decision module: constructs a color temperature decision model to adjust the color temperature of the observation light 4.

[0049] The algorithm trigger module includes:

[0050] A data acquisition unit is used to capture the X-ray image;

[0051] Image processing unit, which performs grayscale conversion and noise reduction preprocessing on X-ray images;

[0052] The feature extraction and analysis unit extracts the texture features of the image and uses the sliding window method to analyze the local density features of the image.

[0053] Specifically, when the X-ray film is placed on the observation light panel of the medical imaging-assisted diagnosis device and the doctor begins to read the film, the system software built into the device immediately triggers the image acquisition program. The high-resolution industrial camera (with a resolution of 5000×3000 pixels, low noise, and high dynamic range characteristics) located at the top of the device and precisely aimed at the observation light panel starts working simultaneously, continuously capturing X-ray film images at a frame rate of 25 frames per second to ensure high-sensitivity monitoring of subtle changes in the image. Each frame of image data is temporarily stored in the device's high-speed cache in a lossless compression format (such as PNG format). The cache capacity is set to accommodate 10 minutes of continuous image data collection to avoid data overflow and loss, and to ensure the continuity and integrity of data in subsequent processing links;

[0054] After reading the newly acquired image frame from the buffer, the grayscale processing flow is first entered. Based on the weighted average method, the color image (originally based on the RGB color space) is converted into a single-channel grayscale image. Through this conversion, the color information redundancy is removed and the grayscale level changes of the image are focused, which meets the needs of X-ray film diagnosis that mainly relies on grayscale contrast features. Then, a two-dimensional adaptive median filter noise reduction operation is performed on the grayscale image. The filter kernel size is dynamically adjusted according to the local image noise characteristics. A 3*3 pixel filter kernel is used in the relatively stable noise area. In the area with large noise fluctuations (judged by a predefined noise variance threshold, the threshold is set to 30, based on a large number of clinical sample statistics), it is switched to a 5*5 pixel filter kernel for more powerful noise suppression. The formula is similar, aiming to eliminate the interference such as salt and pepper noise and Gaussian noise generated during the imaging process to the greatest extent, restore clear image texture, and use the grayscale co-occurrence matrix to extract texture features at multiple scales in the preprocessed grayscale image.

[0055] The color temperature decision module includes:

[0056] The model building unit builds an intelligent color temperature decision model based on fuzzy logic. First, the fuzzy logic system is initialized and the input variable is defined as the texture features extracted and quantified as above.

[0057] Model inference unit, when the suspected lesion area triggers the model, the color temperature of the observation light is accurately adjusted;

[0058] Specifically, an intelligent color temperature decision model based on fuzzy logic is constructed. First, the fuzzy logic system is initialized, and the input variables are defined as the above-mentioned extracted and quantified texture features (normalized contrast, correlation, energy, entropy), local density features (grayscale standard deviation) and edge contour features (contour length, closed area), and the output variable is the recommended color temperature adjustment value ΔT;

[0059] When the suspected lesion area triggers the model, the input variables are fuzzified by the membership function, and Mamdani fuzzy reasoning is performed based on the fuzzy rule base. Calculate the trigger strength α of each rule i , take the minimum membership value of the input variable, integrate all the rule triggering results to get the fuzzy output set, and use the centroid method to defuzzify and find the accurate color temperature adjustment value ΔT:

[0060]

[0061] Where n is the number of trigger rules, ΔT i It is the recommended adjustment value of rule i, based on which the precise adjustment amount of the color temperature of the observation lamp is determined to achieve dynamic adaptation to the needs of lesion observation and assist doctors in efficient diagnosis.

[0062] Working principle: The present invention provides an auxiliary diagnosis device for medical images, aiming to provide doctors with a working platform that integrates stable fixation of X-ray films, light adaptation and adjustment, and intelligent auxiliary diagnosis. Each component works closely together to help doctors accurately and efficiently interpret X-ray image information. The support table 1 serves as the basic bearing structure, providing stable support for the observation table 2 and its accessories above, and giving it the ability to flexibly adjust the height and angle; the locking mechanism 3 on the observation table 2 is responsible for safely and accurately fixing the X-ray film, and the synchronization mechanism 5 cooperates with the action of the locking mechanism 3 to adjust the illumination range of the observation lamp 4 in real time, while the auxiliary diagnosis system intelligently adjusts the color temperature of the observation lamp 4 according to the image characteristics, and comprehensively optimizes the film reading environment and diagnostic support, as follows:

[0063] In the initial state, due to the tension of the spring 309, the card plate 307 is in an open state, which is convenient for the placement of the X-ray film. The placement frame 304 is designed according to the size specifications of common X-ray films, providing a regular placement space and initial positioning guide for the X-ray film. When the X-ray film is pushed along the placement frame 304 and touches the card plate 307, the X-ray film applies an external force to cause the card plate 307 to rotate around the rotation axis 1 306, and the short rod 305 limits the rotation range of the card plate 307 and regulates the path to prevent it from deflecting out of control. When the X-ray film is fully in place, the spring 309 uses the elastic restoring force to pull the card plate 307 through the rotation axis 2 308 so that it tightly clamps the X-ray film. The rubber pad 311 at the bottom of the card plate 307 is soft and has a large friction coefficient. It not only protects the X-ray film from scratches and maintains the integrity of the image, but also enhances the clamping stability and resists the slight vibration interference of the observation platform 2, ensuring that the X-ray film is fixed reliably. Size adaptation and coordinated adjustment: The moving seat 302 can slide freely in the slide rail 301, and can flexibly adjust the position according to the actual size of the X-ray film. Multiple moving seats 302 are connected by telescopic rods 310 to form a linkage system. When a moving seat 302 moves due to the need to adapt to the size of the X-ray film, the telescopic rod 310 drives other moving seats 302 to move synchronously, ensuring that each engaging component 303 operates in coordination, achieving accurate and unified fixation of X-ray films of different specifications, and adapting to a variety of clinical film reading scenarios;

[0064] The core of the synchronization mechanism 5 is to dynamically adjust the illumination area of ​​the observation lamp 4 according to the fixed position of the X-ray film. When the moving seat 302 slides on the slide rail 301, the fixed rod 501 moves synchronously with it. One end of the fixed rod 501 is connected to the moving seat 302, and the other end is connected to the slide 502 of the sliding rheostat 503. The displacement of the moving seat 302 accurately pulls the slide 502 to slide on the outer wall of the sliding rheostat 503. According to the electrical principle, the change of the position of the slide 502 causes the change of the resistance value of the connected circuit. Since the terminal of the sliding rheostat 503 is electrically connected to the observation lamp 4 to form a control circuit, according to Ohm's law (where I is the current intensity, U is the power supply voltage, and R is the resistance value). When the slider 502 increases the resistance, the current decreases, the brightness of the observation lamp 4 decreases, and the illumination range decreases; conversely, the resistance decreases, the current increases, the light becomes brighter, and the illumination range expands. In this way, it can cleverly match the actual placement position and size of the X-ray film, dynamically adjust the illumination area, ensure that the key parts of the X-ray film are always covered by bright and uniform light, and provide high-quality visual conditions for doctors to observe;

[0065] When the X-ray film is in place and the doctor starts reading it, the high-resolution industrial camera on the top of the device starts up, capturing images at 25 frames per second and 5000×3000 pixels, and storing them in a large-capacity high-speed cache area to ensure data integrity, continuity and lossless compression (such as PNG format), and sensitively monitor subtle changes in the image. After reading the image frame from the cache, it is first grayscaled, and the color image is converted to a single-channel grayscale image using the weighted average method, focusing on grayscale contrast. It is then denoised using a two-dimensional adaptive median filter, and the 3×3 or 5×5 filter kernel is switched according to the noise variance threshold to remove salt and pepper, Gaussian noise, and restore the texture. The grayscale co-occurrence matrix is ​​then used to extract texture features at multiple scales, and the local density features of the image are analyzed to lay a solid data foundation for subsequent diagnosis;

[0066] Construct an intelligent color temperature decision-making model based on fuzzy logic, initialize the fuzzy logic system, define texture features, local density features, etc. as input variables, divide the fuzzy language set (such as texture contrast set to "low, medium, high") and determine the membership function, build a huge fuzzy rule base based on a large amount of clinical experience and data, and use genetic algorithms to optimize rule weights and membership parameters to improve adaptability.

[0067] Real-time decision execution: When the image feature data exceeds the threshold to trigger the model, the input variable is fuzzified by the membership function, and the comprehensive result of the trigger strength of each rule (the minimum membership of the input variable) is taken according to the fuzzy rule base Mamdani reasoning. Then the center of gravity method is used to defuzzify and obtain the precise color temperature adjustment amount. The observation light 4 is driven to accurately switch the color temperature to adapt to the needs of lesion observation and assist doctors in efficiently identifying lesions.
