Description

Technical Field

[0001] This invention relates to the field of medical imaging technology, and specifically to a medical image processing auxiliary device and method. Background Technology

[0002] Medical imaging refers to the methods of generating images of the internal structure and function of the human body using various technologies. These images are used for disease diagnosis, treatment guidance, and efficacy evaluation. It is an indispensable tool in modern medicine, allowing doctors to "see" the internal condition of the human body and avoid unnecessary surgery or treatment.

[0003] Traditional supine chest X-ray machines require patient positioning adjustments between supine and lateral positions, making it difficult for patients to determine if the positioning is correct. Furthermore, patients with respiratory distress, pancreatitis, or thoracic vertebral fractures may experience difficulty breathing and pain while supine, preventing them from extending their trunks and causing motion artifacts in the images, thus affecting treatment and diagnosis. To address this issue, the existing Shanghai Baiteng Medical upright chest X-ray machine includes a support column with a sliding robotic arm. An examination plate and an X-ray machine are fixedly connected to both ends of the robotic arm. The height of the X-ray machine and the examination plate can be adjusted using the robotic arm to suit the patient's height. When the patient brings their chest cavity close to the examination plate, they use their shoulders and elbows to bring the chest cavity into contact with the plate. Once in contact, the X-ray machine begins scanning and imaging.

[0004] In practice, although the patient's position is determined by placing their chest cavity close to the examination board, and then X-ray imaging is performed, the patient's elbow may not be able to voluntarily place it close to the examination board when the patient moves their chest cavity close to the examination board. As a result, the patient's chest cavity and the examination board cannot fit together, leading to image artifacts.

[0005] Therefore, the present invention proposes a medical image processing auxiliary device and method to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a medical image processing auxiliary device and method that places the patient's elbow close to the examination board, thereby ensuring that the patient's chest cavity fits against the examination board and preventing image artifacts.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A medical image processing auxiliary device includes a human-computer interaction screen, a support column, and a U-shaped fixing frame. The support column is provided with a sliding assembly for controlling the vertical sliding of the U-shaped fixing frame. An X-ray machine and an examination plate are respectively fixedly connected to both ends of the U-shaped fixing frame. The X-ray machine is signal-connected to a control system. A first electrically controlled cylinder is fixedly connected to the bottom of the U-shaped fixing frame near the examination plate. The first electrically controlled cylinder is signal-connected to the control system. A connecting block is fixedly connected to the output shaft of the first electrically controlled cylinder. A U-shaped connecting rod is fixedly connected to the side wall of the connecting block away from the first electrically controlled cylinder. Both ends of the U-shaped connecting rod are fixedly connected to a fixing box, which is located on both sides of the examination plate. The inner wall of each fixing box is equipped with a first air bladder, which is connected to an air pump. The air pump is connected to the control system. A second air bladder is fixedly connected to the top of the examination plate. The second air bladder is equipped with a filling component for inflating the second air bladder. Before the patient undergoes the examination, the patient places their elbow in the fixing box. The control system controls the air pump to inflate the first air bladder to fix the patient's elbow. Then, the control system controls the first electric cylinder to move the connecting block closer to the examination plate. The connecting block drives the U-shaped connecting rod and the fixing box to move closer to the examination plate.

[0008] The technical principle of the above solution is as follows: The height of the U-shaped fixation frame is adjusted by the sliding component so that the examination plate and the patient's chest cavity are at the same level. The patient's elbows are placed in the corresponding fixation boxes. The control system controls the air pump to inflate the first airbag to fix the elbows. After fixation, the output shaft of the first electric cylinder is controlled to retract to pull the connecting block, so that the connecting block drives the U-shaped connecting rod to move away from the examination plate, thereby driving the fixation box to move closer to the examination plate. At the same time, the first electric cylinder pulls the connecting block to start the filling component to inflate the second airbag.

[0009] The above-mentioned solution has the following advantages: Compared with the existing technology, this solution simulates the action of medical staff assisting in pressing the patient's elbow by fixing the patient's elbow to both sides of the examination board and pulling it towards the side of the examination board. When the patient's elbow and shoulders are in contact with the examination board, the patient's chest cavity is in contact with the examination board. At the same time, the first electric cylinder pulls the connecting block to trigger the gas change of the filling component, so that the gas flows into the second air bladder for filling. The second air bladder supports the patient's jaw to help the patient's chest cavity fit with the examination board.

[0010] Furthermore, the sliding assembly includes a sliding groove, which is opened inside the support column. A sliding rod is slidably fitted inside the sliding groove. A second electric control cylinder is fixedly connected to the top wall of the sliding groove. The second electric control cylinder is connected to the control system signal. The sliding rod is fixedly connected to the output shaft of the second electric control cylinder. The sliding rod extends outside the sliding groove, and the end of the sliding rod away from the sliding groove is fixedly connected to a U-shaped fixing frame.

[0011] Beneficial effect: The second electric control cylinder controls the slide rod to slide in the slide groove, thereby driving the U-shaped fixing frame to slide up and down to adjust the height.

[0012] Furthermore, the filling component includes a channel that communicates with the second airbag, and a push-pull cavity that is connected to the other end of the channel. The push-pull cavity is fixedly connected to the side wall of the first electronically controlled cylinder, and the connecting block is connected to the side of the push-pull cavity side wall away from the first electronically controlled cylinder.

[0013] Beneficial effects: The push-pull chamber and the second airbag are connected by a channel. The push-pull chamber is compressed by the output shaft of the second electric cylinder and the connecting block. When the connecting block moves closer to the first electric cylinder, it compresses the gas in the push-pull chamber. The gas enters the second airbag through the channel to fill it. This makes it easier to lift the patient's jaw while pulling the patient's elbow, thereby improving the fit between the patient's chest cavity and the examination plate.

[0014] Furthermore, the control system includes: The pressure monitoring module is used to detect the pressure on the patient's elbow in order to determine the fixation status. Both the pressure monitoring module and the pressure sensor are connected to the signal. The recognition module is used to identify the placement of the affected limb and the movement distance of the fixation box; The image acquisition module is located on the side of the examination plate closest to the X-ray machine. It is used to receive the attenuated X-rays after they penetrate the human body and convert the attenuated X-rays into electrical signals for imaging. The image processing module is used to process the electrical signals after X-ray conversion, convert the electrical signals into digital signal images, and display them in real time on the human-machine interface screen for easy judgment. The data storage and communication module is used to save and transmit qualified images processed by the image processing module, so as to facilitate data retrieval and integration with the hospital information system; The control module receives the pressure signal detected by the pressure monitoring module, as well as the fixation signal and the movement distance signal after fixation identified by the identification module. It processes the pressure signal, fixation signal and distance signal to determine the fit between the patient's chest cavity and the examination board, and generates corresponding control outputs based on the processing results.

[0015] Furthermore, the identification module includes a laser ranging unit and an infrared photoelectric unit. The laser ranging unit is located on the side wall of the connecting block, and the infrared photoelectric unit is located inside the fixing box. The laser ranging unit is used to measure the distance between the connecting block and the inspection plate; The infrared photoelectric unit is used to detect whether the patient's elbow is fully inserted into the fixation box.

[0016] Beneficial effects: The infrared photoelectric unit identifies the placement of the elbow within the fixed box, and the laser ranging unit identifies the movement distance of the connecting block, thereby determining the movement distance of the fixed box.

[0017] Furthermore, the image processing module includes an image correction unit, an image adjustment unit, an image determination unit, and an image processing unit; Image correction unit is used to eliminate detector noise, calibrate pixel response, and correct geometric distortion; An image conditioning unit is used to optimize image quality, suppress noise, adjust dynamic range, and enhance edge details; The image determination unit is used to analyze image quality in real time and evaluate the illumination range, exposure dose, and motion artifacts. The image processing unit is used to generate warnings or output optimized images based on the judgment results and transmit them to the storage module.

[0018] Beneficial effect: The image processing module converts the information collected by the image acquisition module into a clear digital image and sends it to the human-computer interaction screen for preview to check whether the imaging is up to standard.

[0019] Furthermore, the data storage and communication module includes a cache unit, a storage management unit, and a database unit; The buffer unit receives DICOM format image data from the image processing module; The storage management unit categorizes and migrates data according to preset strategies; The database unit maps DICOM tags to storage paths and records device status logs and operation audits.

[0020] Beneficial effects: The output images are archived and transmitted to the hospital system through the data storage and communication module, so that doctors can see the results immediately and make a quick judgment on the patient's condition.

[0021] Furthermore, a medical image processing assistance method includes the following steps: S1: Height Adjustment: The height of the examination board can be adjusted according to the patient's height via the control module; S2: Fixing the elbow: The patient places their elbow in the fixation box. The infrared photoelectric unit identifies the position of the patient's elbow. Then, the control module controls the air pump to inflate and fix the first airbag based on the signal feedback from the infrared photoelectric unit. The fixation status is judged by the pressure monitoring module. S3: Adjusting body position: Fix the elbow in the fixed box, and the control module controls the first electric cylinder to move the fixed box closer to the inspection plate. The distance between the connecting block and the inspection plate is identified by the laser ranging unit, and then the movement distance of the fixed box is controlled. S4: Illumination Imaging: After the chest cavity is attached to the examination plate, the control module controls the X-ray machine to emit X-rays, and the image acquisition module receives the X-rays after they penetrate the human body and converts them into electrical signals. S5: Image Processing: The electrical signal converted by the image acquisition module is converted into a clear image by the image processing and preview module and displayed on the human-computer interaction screen in real time. After the preview image is confirmed to be correct, the image is transmitted to the data storage and communication module for saving and synchronization.

[0022] Furthermore, the laser ranging unit in S2 includes a laser transmitter and a laser receiver. It calculates the distance by measuring the time it takes for the laser signal to travel from emission to being reflected by the target and returning to the receiver, using the constant speed of light.

[0023] Furthermore, the infrared photoelectric unit in S2 includes several infrared sensors. When more than a set number of infrared sensors are triggered, it is determined that the elbow has been fully inserted.

[0024] Beneficial effects: The automated fixation and positioning mechanism significantly improves examination efficiency and standardization. After the patient's elbow is fixed by an airbag, it is precisely moved by the first electrically controlled cylinder, avoiding the uneven force problem of traditional manual assistance. This reduces the operator's labor intensity and ensures the standard of positioning. At the same time, the second airbag inflates synchronously with the traction action of the first electrically controlled cylinder, providing adaptive support for the jaw and making the chest fit more closely. This is especially suitable for patients who are weak, in pain, or have difficulty breathing, reducing their burden of active cooperation. The control system integrates pressure monitoring and photoelectric recognition modules, providing real-time feedback on fixation status and displacement data, providing dual protection for operational safety and preventing excessive traction or fixation failure. The image processing and communication module realizes an integrated "capture-preview-archive" process, allowing doctors to instantly judge image quality and synchronize it to the hospital system, greatly shortening the diagnostic waiting time. The overall design, through mechanical coordination and intelligent control, eliminates artifacts while taking into account patient comfort and optimized utilization of medical resources.

[0031] The following detailed description illustrates the specific implementation method: Example 1:

[0032] As attached Figure 3As shown: A medical image processing auxiliary device includes a human-computer interaction screen, a support column 1, and a U-shaped fixation frame 2. The U-shaped fixation frame 2 is mounted on the support column 1, and the human-computer interaction screen is fixedly connected to the support column 1. The preferred model of the human-computer interaction screen is Siemens SIMATIC HMI KTP700 Basic. An X-ray machine 3 and an examination plate 4 are welded to both ends of the U-shaped fixation frame 2, respectively. The X-ray machine 3 is connected to a control system. Since patients have varying heights, the support column 1 is equipped with an adjustable sliding component for the U-shaped fixation frame to adjust the height of the examination plate 4 and the X-ray machine 3 so that they are at the same level as the patient's chest cavity. (See attached image.) Figure 4 As shown, the sliding assembly includes a slide groove 12 opened in the support column 1, a slide rod 13 slidably fitted in the slide groove 12, a second electric control cylinder 14 welded to the top wall of the slide groove 12, the second electric control cylinder 14 preferably being an Aerotech LMS15, the second electric control cylinder 14 being signal connected to the control system, the slide rod 13 being welded to the output shaft of the second electric control cylinder 14, the slide rod 13 extending outside the slide groove 12, and the end of the slide rod 13 away from the slide groove 12 being welded to a U-shaped fixing frame; After adjusting the examination plate 4 to the height of the patient's chest cavity, the patient's chest cavity should be in contact with the surface of the examination plate 4. However, due to the convex curved surface of the chest cavity and the patient's lack of flexibility, the chest cavity and examination plate 4 may not be able to fit completely together, which can easily produce artifacts when taking chest X-rays, affecting the treatment judgment. Therefore, as shown in the attached... Figure 3 and attached Figure 5 As shown, a first electric control cylinder 5 is welded to the bottom of the U-shaped fixing frame near the inspection plate 4. The preferred model of the first electric control cylinder 5 is IAI RCP4. The first electric control cylinder 5 is connected to the control system signal. A connecting block 6 is welded to the output shaft of the first electric control cylinder 5. A U-shaped connecting rod 7 is welded to the side wall of the connecting block 6 away from the first electric control cylinder 5. Fixing boxes 8 are welded to both ends of the U-shaped connecting rod 7. The two fixing boxes 8 are located on both sides of the inspection plate 4. A first airbag 9 is provided on the inner wall of each fixing box 8. An air pump 10 is welded to the U-shaped fixing frame 2. The air pump 10 is connected to the first airbag 9. The preferred model of the air pump 10 is KNF NMP. 830, each of the first airbags 9 is equipped with a pressure sensor. The pressure sensor and the air pump 10 are both connected to the control system signal. The pressure monitoring module is used to detect the pressure on the patient's elbow to determine the fixation status. The top of the examination plate 4 is welded with a second airbag 11. The second airbag 11 is equipped with a filling component for inflating the second airbag 11. The filling component includes a channel 15, which is connected to the second airbag 11. The other end of the channel 15 is connected to a push-pull cavity 16. The push-pull cavity 16 is welded to the side wall of the first electric cylinder 5. The output shaft of the first electric cylinder 5 is located in the push-pull cavity 16, and the connecting block 6 is welded to the output shaft of the first electric cylinder 5. The connecting block 6 is connected to the side wall of the push-pull cavity 16 away from the first electric cylinder 5. To achieve automated elbow fixation and patient positioning adjustment, and to facilitate doctors in obtaining examination results, as shown in the attached document... Figure 1 As shown, the control system also includes an identification module, an image acquisition module, an image processing and preview module, and a data storage and communication module. The identification module includes a laser ranging unit and an infrared photoelectric unit. The laser ranging unit is located on the side wall of the connecting block 6, and the infrared photoelectric unit is located inside the fixing box 8. The laser ranging unit is used to measure the distance between the connecting block 6 and the examination plate 4, and the infrared photoelectric unit is used to detect whether the patient's elbow is completely placed inside the fixing box 8. The image acquisition module is located on the side of the examination plate 4 near the X-ray machine 3. The image acquisition module is used to receive the attenuated X-rays after they penetrate the human body and convert the attenuated X-rays into electrical signals. The image processing and preview module is used to process the electrical signals after the X-rays are converted, convert the electrical signals into digital signal images, and display them in real time on the human-machine interface screen for easy judgment. The data storage and communication module is used to save and transmit images to enable data retrieval and integration with the hospital information system.

[0033] The specific implementation process is as follows: First, according to the patient's height, a height adjustment command is sent to the control module through the human-machine interface screen. The control module starts the second electric control cylinder 14 to drive the slide rod 13 to rise and fall in the slide groove 12 of the support column 1, which drives the U-shaped fixing frame welded to the end of the slide rod 13 to move as a whole until the X-ray machine 3 and the examination plate 4 are adjusted to the horizontal position of the patient's chest cavity; then the patient stands facing the examination plate 4 and puts the chest cavity against the plate surface; The doctor then instructs the patient on positioning, guiding them to place their elbows within the fixation boxes 8 on either side. The control module adjusts the position. First, an infrared photoelectric unit inside the fixation box 8 detects that the elbow is fully inside. Then, the control module activates the air pump 10 to inflate the first airbag 9. The pressure monitoring module provides real-time feedback of elbow pressure data to the control module. Inflation stops when the pressure reaches a preset safety threshold, achieving flexible fixation. After fixing the patient's elbow, the control module controls the first electric cylinder 5, welded to the bottom of the U-shaped fixation frame, to pull the connecting block 6. This causes the U-shaped connecting rod 7 welded to the connecting block 6 to move the two fixation boxes 8 towards the examination plate 4. Simultaneously, the elbow placed within the fixation box 8 moves closer to the examination plate 4. The movement of the first electric cylinder 5, which in turn causes the patient's shoulder and chest cavity to fit against the examination plate 4, causes the connecting block 6 to move closer to the first electric cylinder 5. This causes the connecting block 6 to compress the air in the push-pull cavity 16, allowing the gas in the cavity to be forced into the second airbag 11 through the channel 15 and inflate it. The inflation of the second airbag 11 lifts the patient's jaw upwards, which automatically causes the chest cavity to push forward, making the patient's chest cavity fit more closely against the examination plate 4. At the same time, the laser ranging unit continuously measures the change in the distance between the connecting block 6 and the examination plate 4. The control module controls the stroke of the first electric cylinder 5 based on this data to ensure that the patient's chest cavity fits against the examination plate 4 while preventing the patient's elbow from twisting, and to match the degree of inflation of the second airbag 11 with the patient's body shape. After the body position is fixed, the control module controls the X-ray machine 3 to emit X-rays that penetrate the human body. The image acquisition module located on the back of the examination panel 4 receives the attenuated X-rays and converts them into electrical signals. The image processing and preview module converts the signal into digital images and displays them in real time on the human-computer interaction screen for doctors to diagnose. The data storage and communication module simultaneously archives the images and transmits them to the hospital information system. The patient's elbows are fixed in place by the fixing box 8 and moved closer to the examination plate 4, allowing the patient's chest cavity to fit against the examination plate 4. When the elbows are moved, the movement of the first electric cylinder 5, through a linkage design, inflates the second airbag 11, raising the patient's chin and thus lifting the patient's chest to fit against the examination plate 4, increasing the fit between the patient's chest cavity and the examination plate 4. At the same time, the fixing box 8 reduces the difficulty for doctors to give patients instructions on body position adjustment. Doctors only need to tell the patient to place their chin in the first airbag 9 and their elbows in the corresponding fixing boxes 8. After the patient is in the correct position, the body position adjustment is automatically performed by the control system. This not only reduces the difficulty of guidance for doctors but also the difficulty of execution for patients, improving the efficiency of diagnosis.

[0034] The medical image processing auxiliary device of Example 1 was compared with a traditional vertical chest X-ray machine. The specific experiment is as follows: Experimental Objectives: Quantify the artifact reduction effect: compare the artifact incidence rate in chest radiography between traditional upright chest X-ray machines and the new device; evaluate the positional fit efficiency: measure the fit time and fit accuracy between the patient's chest cavity and the examination plate under the two devices; verify the optimization of the operation process: analyze the simplification effect of the automation functions of the new device (such as elbow fixation and jaw support) on the operation steps.

[0035] Experimental steps: 1. Experimental Grouping Experimental group: This device, 20 cases; Control group: Traditional vertical X-ray machine (Shanghai Baiteng Medical), 20 cases; Patient demographics in the control and experimental groups: aged 18-25 years, including 5 patients with simulated dyspnea.

[0036] 2. Operating Procedures Experimental group: The control system automatically adjusts the height of the inspection plate; the infrared photoelectric unit identifies the elbow → the airbag inflates and fixes it; the first electric cylinder automatically pulls the elbow + the second airbag supports the jaw; automatic shooting → real-time preview → archiving.

[0037] Control group: The technician manually adjusted the height of the robotic arm; the technician verbally instructed the patient to apply the elbow to the plate; the patient applied the plate voluntarily, and the technician assisted with pressing; the image was manually taken and then manually transmitted to the workstation for processing.

[0038] 3. Data Collection Fit accuracy: The laser ranging unit records the gap between the chest cavity and the examination plate (unit: mm); Artifact scoring: Blindly evaluated by 3 radiologists (1–5 points, 1 = severe artifacts, 5 = no artifacts); Operation time: Record the total time (in seconds) from patient placement to completion of imaging; Comfort feedback: Patient questionnaire score (1–10, 10 = most comfortable).

[0039] Experimental data: interthoracic space (mm) 1.2±0.3 5.8±1.5 Artifact rating 4.6±0.4 2.9±0.8 Operation time (seconds) 86±12 142±25 Patient comfort 8.5±1.1 6.0±1.7 Experimental conclusion: Significantly reduced artifacts: This device, through automated elbow traction and jaw support, controls the chest cavity fit gap within 1.2mm, improving the artifact score by 58.6%, especially improving the imaging quality for frail patients; Improved operational efficiency: The fully automated process (height adjustment → fixation → imaging → archiving) shortens operation time by 39.4% and reduces the workload of technicians; Optimized patient experience: Flexible airbag fixation and mechanical traction avoid uneven manual pressure, improving patient comfort by 41.7%.

[0040] Example 2: As attached Figure 2 As shown, a medical image processing assistance method includes the following steps: S1: Height Adjustment: The height of the examination board 4 can be adjusted according to the patient's height via the control module; S2: Fixing the elbow: The patient places their elbow in the fixation box 8. The infrared photoelectric unit identifies the position of the patient's elbow. Then, the control module controls the air pump 10 to inflate and fix the first airbag 9 based on the signal feedback from the infrared photoelectric unit. The fixation status is judged by the pressure monitoring module. S3: Adjusting body position: Fix the elbow in the fixing box 8, and the control module controls the first electric cylinder 5 to move the fixing box 8 closer to the inspection plate 4. The distance between the connecting block 6 and the inspection plate 4 is identified by the laser ranging unit, and then the moving distance of the fixing box 8 is controlled. S4: Illumination Imaging: After the chest cavity is attached to the examination plate 4, the control module controls the X-ray machine 3 to emit X-rays, and the image acquisition module receives the X-rays after penetrating the human body and converts them into electrical signals. S5: Image Processing: The electrical signal converted by the image acquisition module is transformed into a clear image by the image processing and preview module, and the image is displayed on the human-machine interface screen in real time. After the preview image is confirmed to be correct, the image is transmitted to the data storage and communication module for storage and synchronization. To ensure that the infrared photoelectric unit can accurately identify the placement of the elbow, the infrared photoelectric unit in S2 includes several infrared sensors. The preferred model of the infrared sensors is Omron EE-SX671. When more than a set number of infrared sensors are triggered, it is determined that the elbow has been fully placed. To ensure that the moving distance of the fixed box 8 is appropriate and to prevent excessive moving distance from causing elbow sprains, the laser ranging unit in S2, which includes a laser emitter and a laser receiver, measures the time it takes for the laser signal to travel from emission to reflection by the target and back to the receiver, and calculates the distance using the constant speed of light.

[0041] The specific implementation process is as follows: Height adjustment ensures basic patient positioning, triggering elbow fixation; after the infrared sensor group intelligently identifies complete elbow placement, it automatically triggers air pump 10 inflation and pressure monitoring to form a closed-loop fixation, providing stable support for position adjustment; the laser emitter and receiver work together to provide real-time distance data feedback to drive the electric cylinder displacement, ensuring a precise spatial relationship between the fixation box 8 and the examination plate 4. This standardized position directly guarantees subsequent imaging quality; X-ray emission and image acquisition work collaboratively under a stable position. After X-rays penetrate the human body and form raw image data, the image correction unit performs correction through dark current to eliminate detector background noise, gain calibration to solve pixel response inconsistency problems, bad pixel repair to remove failed pixels, and geometric correction to ensure that the image is distortion-free. The corrected image is processed by an image adjustment unit that applies an adaptive noise reduction algorithm to suppress random noise while preserving texture details. The high dynamic range problem of chest X-ray is solved by dynamic range compression or adaptive histogram equalization, so that the lung field and mediastinal structure are clearly displayed at the same time. Then, edge enhancement technology is combined to finely enhance the rib edges, bronchial texture and lesion boundaries, thereby improving image clarity. The image determination unit performs real-time analysis of clear images based on preset rules. Threshold segmentation or region growing algorithms are used to identify the boundaries of the thoracic cavity and detect positioning markers. It is determined whether the projection range completely covers the lung apex to the costophrenic angle. Histogram analysis of the average gray value of the lung field is used to assess whether the exposure dose is appropriate. The blurring or double shadow in the overlapping area of ​​the ribs and spine is detected to determine respiratory motion artifacts. The exposure conditions are assessed by analyzing the visibility of lung texture behind the heart, and it is determined whether the imaging image can meet the usage standards. Finally, the image processing unit detects the image based on the judgment results obtained by the image judgment unit. If a range is missing, severe motion blur, or exposure deviates significantly from the standard, an alert box immediately pops up on the operation interface to prompt the technician and automatically generates exposure parameter adjustment suggestions. For images that meet the quality standards, the image processing unit automatically applies the final optimized parameters to output a DICOM image and transmits it to the image storage and communication module. At the same time, it transmits the image to the human-machine interface screen. The real-time feedback from the human-machine interface screen allows the operator to verify the imaging effect on-site. After confirmation, the data is archived through the data storage and communication module. Each step is progressively advanced with sensor feedback as the link, ultimately achieving a full-chain optimization effect from body positioning standardization and imaging stability to data integrity.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
