Description

Technical Field

[0001] The present invention relates to the field of information technology, and in particular to a CT inspection system and method based on a transparent touch display screen and an identification code. Background Art

[0002] There is a core technical problem in the CT examination process: how to improve the automation and intelligence level of CT examination under the premise of ensuring the quality of examination and patient safety. This problem involves multiple aspects: First, the accurate acquisition and effective use of patient information is the basis, but traditional methods are prone to errors and inefficient. Secondly, the adjustment of CT equipment parameters often relies on manual experience, which is difficult to achieve accuracy and personalization. Furthermore, the lack of real-time monitoring and timely response mechanism for patient status during the examination process increases safety hazards. In addition, the presentation of examination information is not intuitive enough, which affects the operating efficiency of medical staff. These problems are interrelated and jointly restrict the efficiency and safety of CT examinations. To solve this technical problem, innovation and breakthroughs are needed in multiple links such as patient information management, intelligent equipment control, real-time monitoring and early warning, and information visualization. At the same time, it is also necessary to consider how to organically integrate these technologies to build a coordinated and consistent intelligent CT examination system to achieve comprehensive optimization and upgrading of the examination process. This not only involves the improvement of a single technology, but also requires systematic innovative thinking to cope with the complex challenges in CT examinations. Summary of the invention

[0046] Figure 1 The figure is a schematic diagram of a CT inspection system based on a transparent touch display screen and an identification code according to the present invention.

[0047] Figure 2The present invention is a flow chart of a CT inspection method based on a transparent touch display screen and an identification code. DETAILED DESCRIPTION

[0048] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0049] like Figure 1 , in this embodiment, a CT inspection system based on a transparent touch display screen and an identification code may specifically include a wearable device, a scanning device and a transparent touch display screen;

[0050] The wearable device generates an identification code including basic patient information and scanning protocol information according to the patient examination items.

[0051] The wearable device can be a wristband with a QR code. The QR code contains the patient's basic information, such as name, age, gender, etc., as well as the scanning protocol information of this examination, such as scanning part, scanning range, scanning layer thickness, scanning time, etc. Before the patient is examined, the medical staff will generate the corresponding scanning protocol in the hospital information system according to the patient's examination items, encode the scanning protocol information into the QR code, and then print the QR code on the wristband. After the patient wears the wristband, the QR code on the wristband contains all the patient's examination information. The scanning device can be a QR code scanner, which is set at the entrance of the CT examination room. When the patient enters the examination room, the scanner will automatically scan the QR code on the patient's wristband, read the patient information and scanning protocol information contained therein, and transmit this information to the control system of the CT device. The control system automatically adjusts the scanning parameters of the CT device, such as scanning layer thickness, scanning time, etc., according to the received scanning protocol information, without the need for manual setting by the physician, thereby improving the inspection efficiency. At the same time, the control system will also automatically adjust the position of the examination bed according to the scanning part information, so that the patient's scanning part is aligned with the scanning center, realize automatic positioning, and further improve the inspection efficiency. The transparent touch display screen is arranged on the lead glass observation window of the CT room. The lead glass observation window is used to isolate the rays generated by the CT equipment and protect the staff from radiation. By setting the touch display screen on the lead glass, the doctor can observe the patient's condition through the display screen, and control the CT equipment by touching the display screen without moving back and forth between the console and the lead glass, thereby improving the operation efficiency. The touch display screen is made of transparent material and can remain transparent at ordinary times, which is convenient for the doctor to directly observe the patient; when operation is required, the display screen is adjusted to opaque through electrochromic technology to display the operation interface. Such a design saves space in the CT room and also improves the work efficiency of the doctor.

[0052] The scanning device scans the identification code on the wearable device, obtains the patient's basic information and scanning protocol information, and transmits the patient's basic information and scanning protocol information to a transparent touch display screen arranged on the lead glass window between the CT scanning room and the control room.

[0053] The scanning device can be a QR code scanner, which can quickly identify and decode the QR code logo on the wearable device. The QR code contains the patient's basic information, such as name, age, gender, etc., as well as the scanning protocol of this CT examination, such as parameters such as scanning site, scanning layer thickness, scanning time, etc. The scanner scans the QR code through infrared or visible light, converts the optical signal into a digital signal, and then restores the text information contained in the QR code through a decoding algorithm. After the scanner obtains the patient information and scanning protocol, it will transmit these data to the transparent touch display between the CT room and the control room through a wired or wireless network. The transparent touch display uses transparent conductive film technology, which can perform touch interactive operations while ensuring the clarity of the display screen. The display screen is embedded in the lead glass window, and the doctor can directly observe the status of the patient in the CT room through the display screen, without going back and forth between different display devices, which improves work efficiency. The patient's basic information will be clearly displayed on the interface of the transparent touch screen, including the patient's photo, name, age, gender, medical record number, etc., which is convenient for the doctor to check and confirm. At the same time, the various parameters of the scanning protocol will also be listed and displayed, such as scanning mode, tube voltage / current, collimation width, scanning time, reconstruction algorithm, etc. Doctors can view and make fine adjustments when necessary. There will also be a "Start Scan" button on the interface. After the doctor confirms that the parameters are correct, he can directly start the scanning program through the touch screen, simplifying the cumbersome operation steps. This design of integrating patient information and scanning solutions on the QR code of the wearable device, combined with the use of the transparent touch screen in the CT room, can significantly improve the automation and intelligence level of CT examinations. The traditional method of manually entering information and manually setting parameters is prone to errors and inefficient. The use of QR codes to automatically collect and transmit data can reduce human errors and ensure that the information is accurate. At the same time, the transparent touch screen integrates display and control functions, opens up the information flow, and optimizes the doctor's operating experience and workflow.

[0054] The transparent touch screen displays basic patient information, scanning protocol information and a confirmation operation button. If a confirmation operation is recognized, the movement parameters of the CT device are set according to the basic patient information and the scanning protocol information, and the CT device is controlled to automatically position and scan the patient.

[0055] The transparent touch display screen can display the patient's basic information, such as name, age, gender, medical record number, etc., so that the doctor can quickly check the patient's identity. At the same time, the transparent touch display screen will also display the scanning protocol information of this CT examination, such as parameters such as scanning site, scanning range, scanning layer thickness, scanning time, etc. The doctor can adjust and optimize the scanning protocol through touch operation to meet the needs of different patients and different examinations. After confirming that the patient information and scanning protocol are correct, the transparent touch display screen will pop up a confirmation operation button. After the doctor clicks the confirmation button, the CT control system will automatically calculate the optimal CT equipment movement parameters based on the patient's height and weight and other basic information, combined with the parameters set by the scanning protocol, including the height of the scanning bed, the movement speed of the scanning bed, the rotation speed of the X-ray tube, and the exposure time. The automatic setting of these movement parameters can enable the patient to maintain the most comfortable position during the scanning process and minimize the artifacts caused by position changes. At the same time, the optimized scanning parameters can also minimize the radiation dose received by the patient while ensuring image quality. After completing the parameter setting, the CT control system will control the CT device to automatically position the patient. First, the scanning bed will automatically move to the height that best suits the patient's height, and slowly send the patient to the center of the scanning tube. At the same time, the laser positioning system will project a cross line to facilitate the physician to determine whether the patient is in the center of the scan. The CT device is also equipped with a high-precision three-dimensional surface scanning system that can track the patient's body contour in real time, and fine-tune the patient's position according to the anatomical characteristics of the scanned area to make it completely parallel to the scanned plane. This automatic positioning method can standardize the scanning operation process, improve inspection efficiency, and avoid errors caused by manual positioning. When the patient is positioned, the CT control system will automatically start the scanning program according to the scanning protocol. During the scanning process, the system will monitor the tube current, voltage and other parameters in real time, and dynamically adjust the exposure dose according to the patient's body shape and the absorption difference of the scanned area to obtain the best image quality. At the same time, the system will also monitor and compensate for the patient's physiological movements (such as breathing, heartbeat, etc.) in real time, and minimize motion artifacts by adjusting the data acquisition time window. The entire scanning process is highly automated. Physicians only need to observe the patient's status through a transparent touch screen without manually adjusting parameters, which greatly reduces the difficulty of operation and the risk of errors. After the scan is completed, the CT device will automatically remove the patient from the scanning tube and reset the scanning bed. At the same time, the scanned image will be automatically transmitted to the image post-processing workstation for image reconstruction and post-processing. The physician can view the reconstruction progress and image quality in real time through the transparent touch screen and adjust the reconstruction algorithm and parameters as needed. This real-time interactive image processing method can help physicians quickly obtain high-quality diagnostic images and shorten patient waiting time.

[0056] Furthermore, the transparent touch display screen is also used for:

[0057] Acquire the display area size and resolution of the transparent touch display screen, and determine the information layout scheme of the patient's basic information and scanning protocol information based on the display area size and resolution;

[0058] Adopting the human-computer interaction design principle, a confirmation operation button is set in the touch operation area, and the touch operation area is preset according to the operation habits of medical staff;

[0059] The patient's basic information, scanning protocol information and confirmation operation button are displayed based on the information layout scheme, the human-computer interaction design principles and the transparent display technology. The transparent display technology is used to superimpose the patient's basic information, scanning protocol information and confirmation operation button on the surface of a transparent touch display screen without affecting the medical staff's line of sight.

[0060] In order to determine the best layout of the patient's basic information and scanning protocol information on the transparent touch display screen, the system first needs to obtain the display area size and resolution of the transparent touch display screen. For example, if the display area of ​​the transparent touch display screen is 21.5 inches and the resolution is 1920x1080, the system can design the best information layout based on these parameters. Specifically, the system can divide the display area into different functional areas, such as the patient's basic information area, the scanning protocol information area, and the touch operation area. The size and position of each functional area need to be carefully designed according to the size and resolution of the display screen to ensure the clarity and readability of the information. At the same time, the layout plan also needs to take into account the usage habits and workflow of medical staff to make it more convenient and efficient to operate. For example, the patient's basic information area can be placed in the upper left corner of the display screen, the scanning protocol information area can be placed in the upper right corner, and the touch operation area can be placed below. This layout method conforms to people's reading habits and is also convenient for medical staff to quickly find the required information. When designing the touch operation area of ​​the transparent touch display screen, it is necessary to fully consider the human-computer interaction design principles to improve the operating efficiency and accuracy of medical staff. According to the operation habits of medical staff, some commonly used operation buttons such as "Confirm", "Cancel", "Pause" and so on can be preset in the touch operation area. The size, position and color of these buttons need to be carefully designed to ensure that medical staff can complete the operation quickly and accurately. For example, the "Confirm" button can be set to green and located in the center of the touch operation area. Its size should be large enough to facilitate medical staff to click. At the same time, the spacing between buttons also needs to be reasonably set to avoid misoperation. In addition, the touch operation area can also dynamically adjust the layout and function of buttons according to different operation scenarios to meet the actual needs of medical staff. For example, during the scanning process, the "Pause" button can be placed in a more eye-catching position so that medical staff can quickly pause the scan when needed. In order to clearly display the patient's basic information, scanning protocol information and confirmation operation buttons on the transparent touch display without affecting the medical staff's line of sight, transparent display technology is required. Transparent display technology can superimpose image information on the surface of the transparent touch display, making it look like it is suspended in mid-air without blocking the medical staff's line of sight. At the same time, transparent display technology can also automatically adjust the brightness and contrast of the display according to changes in ambient light to ensure that image information can be clearly seen in any situation. In practical applications, transparent touch screens can use different transparency settings according to different display contents. For example, for basic patient information and scanning protocol information, the transparency can be set higher to make it more eye-catching and easy to read; while for confirmation operation buttons, the transparency can be set lower to avoid interfering with the vision of medical staff.At the same time, the transparent touch screen can also use a variety of visual elements such as color, font, animation, etc. to attract the attention of medical staff and improve their enthusiasm and accuracy in operation. For example, in the patient basic information area, bright colors and larger fonts can be used to highlight important information; in the scanning protocol information area, icons, animations, etc. can be used to intuitively display the scanning process; on the confirmation operation button, some eye-catching prompt text or symbols can be added to guide medical staff to operate.

[0061] Furthermore, the transparent touch display screen is also used for:

[0062] If a confirmation operation is recognized, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso contour;

[0063] Determine an optimal scanning position according to the patient's trunk contour and basic information of the patient, and use the optimal scanning position as the target position of the CT device;

[0064] Acquire a CT device movement parameter according to the scanning protocol information, set the CT device movement parameter based on a target position of the CT device, and control the CT device to automatically move to the target position based on the set CT device movement parameter to complete the automatic positioning process of the patient;

[0065] The scanning parameters are determined according to the scanning protocol information, and the scanning parameters are sent to the CT device, and the CT device is controlled to scan the patient according to the scanning parameters, thereby completing the automatic scanning process of the patient.

[0066] If the confirmation operation is recognized, the patient image is segmented by an image segmentation algorithm to obtain the patient's trunk contour. Image segmentation refers to the technology and process of dividing an image into several specific regions with unique properties and extracting targets of interest. For patient images in CT scans, a segmentation algorithm based on the region growing method can be used. The algorithm uses the grayscale, texture and other characteristics of the patient's trunk area as the growth criterion. Starting from the selected seed point, the pixels in the neighborhood that meet the growth criterion are gradually merged into the seed area until there are no more pixels that meet the conditions to be included, and finally the segmentation of the entire trunk area is completed to obtain a clear trunk contour. The optimal scanning position is determined according to the patient's trunk contour and the patient's basic information, and the optimal scanning position is used as the target position of the CT device. The optimal scanning position of the patient needs to comprehensively consider the patient's basic information such as height and weight and the trunk contour characteristics. For example, for chest CT scans, the patient's lungs need to be placed in the optimal position of the scanning beam. The three-dimensional spatial coordinates of the lung area can be obtained by analyzing the patient's trunk contour data, and then combined with the patient's height and weight information, the displacement required to move the CT scanning bed is calculated, so that the patient's lungs are moved to the optimal scanning position. This position is the target scanning position of the CT device. The CT device movement parameters are obtained according to the scanning protocol information, the CT device movement parameters are set based on the target position of the CT device, and the CT device is controlled to automatically move to the target position based on the set CT device movement parameters to complete the patient's automatic positioning process. The scanning protocol information contains various technical parameters of the CT device, such as scanning mode, tube voltage, tube current, scanning layer thickness, etc. It should also include the movement parameters of the CT device, such as moving speed, acceleration, etc. According to the target position of the CT device determined in the previous step, the distance and direction that the CT device needs to move can be calculated. Then, based on the movement parameters of the CT device, the moving motor of the CT scanning bed is controlled to move at a specific speed and acceleration until the CT scanning bed moves to the target position and stops, that is, the patient's automatic positioning process is completed. The entire positioning process does not require manual intervention, which improves work efficiency. The scanning parameters are determined according to the scanning protocol information, and the scanning parameters are sent to the CT device, and the CT device is controlled to scan the patient according to the scanning parameters to complete the patient's automatic scanning process. The scanning protocol information contains a series of scanning parameters, such as scanning mode, tube voltage, tube current, scanning layer thickness, pitch, scanning time, etc. The appropriate combination of scanning parameters can be selected according to the patient's specific examination needs, such as conventional CT, high-resolution CT or low-dose CT. After the scanning parameters are determined, they are sent to the control system of the CT equipment. The CT control system automatically adjusts the working state of the X-ray tube according to the received parameters, and controls the CT scanning bed to perform spiral scanning or axial scanning at a specific speed, and synchronously collects image data.The entire scanning process is carried out automatically. After the scan is completed, the CT device automatically stops and transmits the collected image data to the image workstation for subsequent image reconstruction processing to obtain the final CT image, completing the patient's automatic scanning process.

[0067] Furthermore, the wearable device is also used to obtain patient posture data and heart rate data during the CT scanning process, and transmit the patient posture data and heart rate data to the transparent touch display screen;

[0068] The transparent touch display screen is also used to determine whether the patient's posture change value exceeds a preset change threshold and whether the heart rate exceeds a preset heart rate range based on the received patient posture data and heart rate data. If the patient's posture change value exceeds the preset change threshold or the heart rate exceeds the preset heart rate range, an abnormal part image is generated through the transparent touch display screen.

[0069] The wearable device obtains the patient's posture and heart rate data and transmits them to the transparent touch display. This process can be achieved by building a posture sensor and a heart rate sensor into the wearable device. The posture sensor can be an accelerometer, a gyroscope, etc., which can determine the change of posture by detecting the angle change of various parts of the patient's body. The heart rate sensor can measure the patient's heart rate by photoplethysmography and other methods. The wearable device collects the patient's posture and heart rate data in real time and transmits the data to the transparent touch display through a wireless communication module (such as Bluetooth, WiFi, etc.). After the transparent touch display receives the patient's posture and heart rate data, it needs to make judgments and processes them. First, the posture change threshold and the normal heart rate range must be set. The posture change threshold can be set according to the requirements of the CT scan for the stability of the patient's posture, for example, it is stipulated that the angle change of the patient's head, trunk and limbs cannot exceed 5 degrees. The normal heart rate range can be set according to factors such as the patient's age and gender. The normal heart rate of an adult is generally 60-100 beats / minute. The control system of the transparent touch display compares the patient's real-time posture data with the initial posture data, calculates the posture change value, and determines whether it exceeds the preset threshold. At the same time, it determines whether the patient's heart rate is within the normal range. If the patient's posture change value exceeds the preset threshold or the heart rate exceeds the normal range, the transparent touch display will generate an abnormal part image. For example, if a large change in the patient's head posture is detected, a 3D model image of the head can be displayed on the screen, and the head area can be highlighted in red to prompt the doctor to pay attention. If the patient's heart rate is too fast or too slow, an electrocardiogram can be displayed on the screen to mark the abnormal heart rate interval. Abnormal part images can help doctors quickly locate problems, adjust scanning plans in time, or intervene in patients. At the same time, the transparent touch display can also issue sound and light alarms to remind doctors and patients to pay attention. The patient's posture and heart rate are monitored in real time by wearable devices, combined with the intelligent judgment and abnormal prompt functions of the transparent touch display, the safety and effectiveness of the CT scanning process can be guaranteed. On the one hand, image artifacts and repeated scans caused by changes in patient posture can be avoided; on the other hand, accidents caused by abnormal heart rate can be prevented. This real-time monitoring and intelligent prompt function is particularly important for special patient groups such as the elderly and children, and helps reduce the occurrence of medical errors such as missed diagnosis and misdiagnosis. At the same time, through the visualization of abnormal parts, doctors can more intuitively understand the patient's condition and improve the efficiency of diagnosis and decision-making. In short, the combination of wearable devices and transparent touch screens can improve the intelligence level of CT scanning and ensure the quality and safety of medical care.

[0070] Furthermore, the transparent touch display screen is also used for:

[0071] The continuously collected patient posture data are compared to calculate the posture change value. If the posture change value exceeds the preset change threshold, it is determined that the patient's current posture does not meet the requirements of CT scanning, and prompt information is displayed on the transparent touch screen to guide the patient to adjust the posture;

[0072] Parsing the received patient heart rate data to obtain a heart rate value sequence, calculating the patient's heart rate average value and fluctuation range through the heart rate value sequence, determining whether the heart rate average value falls within a preset heart rate normal range, and determining whether the heart rate fluctuation range exceeds a preset heart rate fluctuation threshold;

[0073] If the heart rate average value does not fall within the preset normal heart rate range or the heart rate fluctuation exceeds the preset heart rate fluctuation threshold, the patient's heart rate is determined to be abnormal, and an abnormal heart rate warning message is displayed to remind medical staff to pay attention to the patient's condition;

[0074] The body part where the abnormality occurs is determined based on the posture data of the patient that does not meet the CT scanning requirements and the heart rate data of the patient with abnormal heart rate, and an abnormal part image is generated based on the body part where the abnormality occurs.

[0075] The transparent touch screen can monitor the patient's posture changes in real time, collect the patient's posture data through sensors, and compare it with the preset standard posture data. Specifically, the infrared depth camera can be used to collect the patient's three-dimensional posture information, extract the coordinates of the key points of the skeleton, calculate the angles of each joint, and obtain a data vector describing the patient's current posture. The vector is calculated by Euclidean distance with the preset standard posture vector to obtain a posture change value. If the value exceeds the preset threshold (such as 10°), it is determined that the patient's current posture does not meet the requirements. At this time, a human body model will be displayed on the transparent touch screen, and the parts with improper postures will be marked in red, and corresponding voice prompts will be given, such as "Please keep your head from turning", "Please lie flat and keep your legs together", etc., to guide the patient to adjust to the correct scanning posture in time. At the same time, the transparent touch screen can also display the patient's heart rate status in real time. By connecting a wireless ECG sensor, the patient's ECG signal is collected at a certain frequency (such as once per second) and transmitted to the control system for processing. The system performs denoising and filtering on the original ECG signal, extracts the R wave peak, calculates the time interval RR between adjacent R waves, and then obtains the instant heart rate according to the formula HR=60 / RR. Arrange the heart rate values ​​of the last minute in chronological order to form a heart rate value sequence. The average value of the sequence is calculated as the patient's average heart rate. Then calculate the difference between the maximum and minimum values ​​in the sequence as the heart rate fluctuation range. The system presets the range of normal adult heart rate, such as 60-100 beats / minute. If the patient's average heart rate exceeds this range, or the fluctuation range exceeds a certain threshold (such as 30 beats / minute), it is determined to be an abnormal heart rate. When an abnormal heart rate is detected, a red warning box will pop up on the transparent touch screen, displaying the patient's real-time electrocardiogram and heart rate values, and an alarm will sound to remind medical staff to come and check. At the same time, the cause of the abnormal heart rate will be analyzed. If it is found that it is caused by a change in body position, the body parts that may affect the heart rate will be marked on the screen, prompting to adjust the body position. If the body position factor is excluded, medical advice will be displayed, such as "Please pay close attention and terminate the examination if necessary". In addition, the system can also associate the patient's posture data with the heart rate data for analysis to determine the body part where the abnormality occurs. For example, if it is found that the patient's heart rate suddenly rises and the posture of the left leg deviates from the standard value, it is speculated that the abnormal heart rate may be caused by discomfort in the left leg. At this time, a human body image is displayed on the transparent screen, and the left leg is marked in red to prompt the doctor to pay special attention. If the abnormal posture and heart rate continue for a period of time without relief, the CT scan image of the left leg is superimposed on the human body image to intuitively show the anatomical structure of the abnormal part, providing more clues for the doctor to determine the cause of the disease. In the above way, the transparent touch display screen can realize the whole process of intelligent monitoring of the patient's status, and timely warn once an abnormality is found, and give intuitive visual prompts to ensure the safety of the patient. At the same time, it also provides more abundant information for medical staff to make diagnostic decisions, which helps to improve the efficiency and accuracy of CT examinations.This human-computer interaction mode breaks the barriers of information transmission in traditional CT rooms, realizes seamless connection and real-time interaction between patients, equipment, and doctors, and represents a new model of diagnosis and treatment that is more intelligent and humane.

[0076] In addition, refer to Figure 2 The present invention further provides a CT inspection method based on a transparent touch display screen and an identification code, the method is applied to the CT inspection system based on a transparent touch display screen and an identification code as described above, the method comprising:

[0077] S101, generating an identification code including basic patient information and scanning protocol information according to the patient examination items, and storing the identification code in a wearable device;

[0078] S102, scanning the identification code on the wearable device by means of a scanning device to obtain basic information of the patient and scanning protocol information, and transmitting the basic information of the patient and scanning protocol information to a transparent touch display screen disposed on a lead glass window between the CT scanning room and the control room;

[0079] S103, displaying the patient's basic information, scanning protocol information and confirmation operation button through the transparent touch screen; if the confirmation operation is recognized, setting the movement parameters of the CT device according to the patient's basic information and scanning protocol information, and controlling the CT device to automatically position and scan the patient.

[0080] An identification code containing basic patient information and scanning protocol information is generated according to the patient's examination items, and the identification code is stored in the wearable device. For example, when a patient needs to undergo a head CT plain scan examination, a QR code or barcode can be generated based on the patient's ID number, name, age, gender and other basic information, as well as scanning parameters of the head plain scan such as tube voltage 120kV, tube current 200mA, scanning layer thickness 5mm, scanning range above the orbital ear line to below the external occipital protuberance. The identification code can be encrypted using an encryption algorithm such as AES or RSA to ensure the security of the patient's information. The generated identification code can be stored in a wearable device such as a wristband or card worn by the patient, which is convenient for the patient to carry and for the CT room staff to read. The identification code on the wearable device is scanned by a scanning device to obtain the patient's basic information and scanning protocol information, and the patient's basic information and scanning protocol information are transmitted to a transparent touch display screen set on the lead glass window between the CT scanning room and the control room. When the patient enters the CT room, the CT room staff can use a dedicated scanning device such as a scanner gun to scan and identify the identification code on the patient's wearable device. The scanning device parses the identification code through a decoding algorithm to obtain the patient's basic information and the scanning protocol information of this examination. In order to ensure scanning efficiency and accuracy, the scanning device can use a high-speed and high-precision scanning module, such as a CCD or CMOS sensor. The acquired patient information and scanning protocol can be transmitted to the transparent touch screen at the lead glass window between the CT room and the control room through a wired network or wireless WiFi for the physician to check and confirm. The transmission process should use an encrypted communication protocol, such as SSL / TLS, to prevent information leakage. The patient's basic information, scanning protocol information and confirmation operation button are displayed on the transparent touch screen. If the confirmation operation is recognized, the CT device movement parameters are set according to the patient's basic information and scanning protocol information, and the CT device is controlled to automatically position and scan the patient. After receiving the patient information and scanning protocol, the transparent touch screen clearly displays key information such as the patient's name, ID, age, examination items, body position, scanning range, tube voltage, tube current, etc. in the form of a list or card in a prominent position on the screen, and a "Confirm to Start Examination" button is displayed at the bottom of the screen. The doctor on duty can clearly see the patient lying properly through the lead glass, and check the patient information and scanning plan on the transparent screen. After confirming that they are correct, click the "Confirm to start the examination" button. The transparent touch screen uses infrared touch technology, supports multi-touch, and has precise positioning. It can be easily operated even if the doctor is wearing gloves. When the transparent screen detects the doctor's confirmation operation, it sends the patient information and scanning protocol parameters to the CT device. The CT device automatically adjusts the height and position of the bed board according to the received parameters, and moves the scanning part such as the head to the scanning center; at the same time, the tube parameters and collimator are set, and the scanning is carried out strictly in accordance with the scanning protocol such as layer thickness 5mm and tube voltage 120kV. The CT device can use a servo motor to accurately control the movement of the bed board to ensure that the patient is positioned accurately.The entire positioning and scanning process is carried out automatically without the need for manual operation by the physician, thus avoiding the errors and inefficiencies of manual operation and improving the standardization and intelligence of the examination.

[0081] Furthermore, the display of basic patient information, scanning protocol information and confirmation operation buttons through the transparent touch screen includes:

[0082] Acquire the display area size and resolution of the transparent touch display screen, and determine the information layout scheme of the patient's basic information and scanning protocol information based on the display area size and resolution;

[0083] Adopting the human-computer interaction design principle, a confirmation operation button is set in the touch operation area, and the touch operation area is preset according to the operation habits of medical staff;

[0084] The patient's basic information, scanning protocol information and confirmation operation button are displayed based on the information layout scheme, the human-computer interaction design principles and the transparent display technology. The transparent display technology is used to superimpose the patient's basic information, scanning protocol information and confirmation operation button on the surface of a transparent touch display screen without affecting the medical staff's line of sight.

[0085] Obtaining the display area size and resolution of the transparent touch display is the basis for designing the information layout. Assume that the size of the transparent touch display is 60 inches and the resolution is 3840×2160 pixels (4K resolution). First, according to the size and resolution of the display area, the screen can be divided into multiple functional areas. For example, the upper part of the screen can be used to display the patient's basic information, such as name, age, gender, examination items, etc., the middle part is used to display the scanning protocol information, such as layer thickness, layer spacing, scanning time, etc., and the bottom is reserved for the touch operation area to place the "confirm" button. In the specific layout, the upper patient basic information area can occupy 20% of the screen, the middle scanning protocol information area occupies 50%, and the bottom touch operation area occupies 30%. Such a layout can ensure the clear display of information and facilitate the operation of medical staff. When setting the confirmation operation button of the touch operation area using the human-computer interaction design principle, the operating habits and visual focus of medical staff should be considered. According to the principle of ergonomics, the confirmation button should be set at the bottom center of the screen, with a size of 100×100 pixels and a striking green color, so that medical staff can quickly find and operate it while observing the patient. In addition, there should be enough blank space around the button to avoid accidental touch. In order to further optimize the operation experience, the button can also be designed with slight vibration feedback to ensure that medical staff can get clear tactile feedback when operating. Based on the information layout scheme and human-computer interaction design principles, transparent display technology is used to superimpose the patient's basic information, scanning protocol information and confirmation operation buttons on the surface of the transparent touch display screen. Transparent display technology is realized through optical coating and LED backlight technology, which can clearly display information without affecting the medical staff's line of sight. For example, when medical staff observe the patient through the transparent screen, the patient's basic information and scanning protocol information displayed on the screen will be superimposed on the patient in a semi-transparent manner, which will not affect the observation and provide necessary information support. The confirmation button is highlighted to ensure that it is still eye-catching in complex environments. In specific implementation, the display effect of the transparent touch display screen can be optimized by adjusting the transparency and contrast. Assume that the transparency is set to 70% and the contrast is set to 80%, which can ensure the visibility of information and ensure that medical staff can clearly observe the patient's condition. In addition, the brightness of the screen can be automatically adjusted according to the ambient light to ensure the best display effect under different lighting conditions. Through the above design, the transparent touch display not only saves space, but also improves the convenience and safety of operation. For example, in an emergency, medical staff do not need to turn around to operate the console, but can complete all operations directly on the transparent screen, which greatly shortens the response time. At the same time, due to the reasonable layout of information and the ergonomic design of the operation buttons, medical staff are not prone to misoperation during operation, which improves the accuracy and efficiency of scanning.In addition, the transparent touch display can also integrate other auxiliary functions, such as real-time heart rate monitoring, respiratory rate display, etc., to further enrich the information acquisition channels for medical staff. For example, during the scanning process, the upper right corner of the screen can display the patient's heart rate and respiratory rate in real time, helping medical staff to grasp the patient's physiological state in a timely manner and ensure the safety of the scanning process. In summary, through reasonable information layout, human-computer interaction design principles and the application of transparent display technology, the transparent touch display plays an important role in the CT scanning process, which not only optimizes the operation process, but also improves the scanning efficiency and safety, providing strong support for the construction and development of modern hospitals.

[0086] Furthermore, if the confirmation operation is recognized, the movement parameters of the CT device are set according to the basic information of the patient and the scanning protocol information, and the CT device is controlled to automatically position and scan the patient, including:

[0087] If a confirmation operation is recognized, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso contour;

[0088] Determine an optimal scanning position according to the patient's trunk contour and basic information of the patient, and use the optimal scanning position as the target position of the CT device;

[0089] Acquire a CT device movement parameter according to the scanning protocol information, set the CT device movement parameter based on a target position of the CT device, and control the CT device to automatically move to the target position based on the set CT device movement parameter to complete the automatic positioning process of the patient;

[0090] The scanning parameters are determined according to the scanning protocol information, and the scanning parameters are sent to the CT device, and the CT device is controlled to scan the patient according to the scanning parameters, thereby completing the automatic scanning process of the patient.

[0091] After the patient enters the CT room, the QR code on the scanning protocol bracelet worn by the patient is scanned by a QR code scanning device to obtain the patient's basic information and scanning protocol information. When the physician confirms that the patient is ready through the touch-sensitive transparent screen, the system will recognize the confirmation operation and start the automatic positioning and scanning process. First, the system uses the image segmentation algorithm in computer vision technology to segment the patient image collected by the CT device. Common image segmentation algorithms include threshold segmentation, region growing, watershed, etc. Through image segmentation, the patient's torso contour can be extracted from the image. The torso contour can be represented as a series of coordinate points that outline the outer boundary of the patient's body. Next, the system comprehensively considers the patient's torso contour information and basic information such as height and weight to calculate the best position for this scan. The best scanning position refers to the position where the CT scanning bed can be moved to the target part for the most comprehensive and clear imaging. This position is usually located in the center of the target part and avoids tissues such as bones and gas that affect the imaging quality. The system sets the calculated best scanning position as the target position of the CT device. According to the acquired scanning protocol information, the system can determine the movement parameters required by the CT device, such as the movement direction, movement distance, and movement speed. Based on the target position, the system sets the movement parameters of the CT device and controls the automatic movement of the CT device until the scanning bed reaches the target position. This process realizes the automatic positioning of the patient, without the need for the physician to manually adjust the patient's position, which improves the accuracy and efficiency of the positioning. After completing the automatic positioning, the system determines the various parameters required for this scan according to the scanning protocol information, such as scanning range, tube voltage, tube current, layer thickness, pitch, etc. These parameters directly affect the imaging quality and radiation dose of the scan. The system sends the optimized scanning parameters to the CT device, controls it to scan according to the parameter settings, and obtains the tomographic image of the patient's target part. The entire scanning process is carried out automatically, and the physician only needs to monitor the scanning progress and image quality in real time through the touch-sensitive transparent screen. In short, the automated CT scanning process based on the scanning protocol bracelet and the touch-sensitive transparent screen makes full use of computer vision, artificial intelligence and other technologies to realize the full process automation control from patient positioning to image acquisition. Compared with the traditional manual operation method, this solution has the following advantages: First, automatic positioning avoids the tedious steps of manually adjusting the body position, improving the inspection efficiency; second, the parameter setting is automatically optimized by the system according to the scanning protocol, reducing human errors and ensuring the consistency of image quality; third, the doctor can realize visual monitoring of the scanning process through the touch-sensitive transparent screen, and the operation is more intuitive and convenient. These advantages not only improve the intelligent level of CT examination, but also bring patients a better and more efficient medical service experience.

[0092] Furthermore, after controlling the CT device to automatically position and scan the patient, the method further includes:

[0093] During the CT scanning process, the patient's posture data and heart rate data are obtained through the wearable device, and the patient's posture data and heart rate data are transmitted to the transparent touch display screen;

[0094] The patient posture data and heart rate data received by the transparent touch display screen are used to determine whether the patient posture change value exceeds the preset change threshold and whether the heart rate exceeds the preset heart rate range. If the patient posture change value exceeds the preset change threshold or the heart rate exceeds the preset heart rate range, an abnormal part image is generated through the transparent touch display screen.

[0095] During the CT scan, the patient's posture data and heart rate data are obtained in real time through a wearable device worn on the patient. The wearable device can be a smart bracelet, smart watch, etc., with a built-in accelerometer, gyroscope, heart rate sensor, etc., which can collect the patient's posture and heart rate information in real time. The acquired data is transmitted to the transparent touch screen in the CT room in real time through a wireless communication module (such as Bluetooth, WiFi, etc.). A special software program runs on the transparent touch screen, which can receive and process the data from the wearable device. The software program will analyze the received patient posture data and calculate the change value of the patient's posture, that is, the degree of deviation of the patient's current posture from the posture at the beginning of the scan. If the calculated posture change value exceeds the preset threshold (such as 5 degrees), it is considered that the patient's posture has changed significantly, which may affect the quality of the scanned image. At the same time, the software program will also determine whether the patient's heart rate exceeds the normal range (such as the normal range of adult heart rate is 60-100 times / minute). When it is determined that the patient's posture change value exceeds the threshold or the heart rate is abnormal, the software program will automatically process and analyze the currently acquired CT image, identify the parts of the image that may have artifacts or contamination, and display the image of the abnormal part in real time on the transparent touch screen to prompt the doctor that there may be problems with the scan. The abnormal part image can be superimposed on the original CT image to mark the abnormal area, or the segmented abnormal part image can be displayed separately and marked with a striking color (such as red). Through the above method, the patient's posture and physiological state can be monitored in real time during the CT scan, and the doctor can be reminded in time once an abnormality is found. This can avoid scanning failure or image quality degradation caused by changes in patient posture or abnormal heart rate, improve the success rate and efficiency of CT scanning, and reduce the patient's radiation dose and discomfort. This method takes advantage of wearable devices and transparent touch screens, organically combines them with CT equipment, and realizes the intelligence and visualization of the scanning process.

[0096] Further, the patient posture data and heart rate data received through the transparent touch display screen determine whether the patient posture change value exceeds a preset change threshold, and whether the heart rate exceeds a preset heart rate range. If the patient posture change value exceeds the preset change threshold or the heart rate exceeds the preset heart rate range, an abnormal part image is generated through the transparent touch display screen, including:

[0097] The patient posture data collected continuously by the transparent touch screen is compared to calculate the posture change value. If the posture change value exceeds the preset change threshold, it is determined that the patient's current posture does not meet the requirements of CT scanning, and prompt information is displayed on the transparent touch screen to guide the patient to adjust the posture;

[0098] Parsing the patient's heart rate data received by the transparent touch display screen to obtain a heart rate value sequence, calculating the patient's heart rate average value and fluctuation range through the heart rate value sequence, judging whether the heart rate average value falls within a preset heart rate normal range, and judging whether the heart rate fluctuation range exceeds a preset heart rate fluctuation threshold;

[0099] If the heart rate average value does not fall within the preset normal heart rate range or the heart rate fluctuation exceeds the preset heart rate fluctuation threshold, the patient's heart rate is determined to be abnormal, and an abnormal heart rate warning message is displayed on the transparent touch screen to remind medical staff to pay attention to the patient's condition;

[0100] The body part where the abnormality occurs is determined based on the posture data of the patient that does not meet the CT scanning requirements and the heart rate data of the patient with abnormal heart rate, and an image of the abnormal part is generated through a transparent touch display based on the body part where the abnormality occurs.

[0101] During the CT scan, the patient's posture and heart rate are important factors affecting the quality and safety of the scan. In order to monitor the patient's posture and heart rate changes in real time, the patient's posture data and heart rate data can be collected through a transparent touch screen, and real-time analysis and judgment can be performed. First, the transparent touch screen can continuously collect the patient's posture data, such as the position and angle information of body parts such as the head, trunk, and limbs. By comparing and analyzing the continuously collected posture data, the change value of the patient's posture, that is, the amplitude of the posture change, can be calculated. A preset posture change threshold is set, such as 5 degrees. If the calculated posture change value exceeds 5 degrees, it is determined that the patient's current posture has deviated from the standard posture originally set and no longer meets the requirements of CT scanning. At this time, the transparent touch screen can display corresponding prompt information, such as "Please keep your body still and do not move", etc., to guide the patient to adjust the posture in time and restore it to the correct scanning posture. Secondly, the transparent touch screen can also receive the patient's heart rate data in real time. By connecting to the electrocardiogram monitor, the continuous value of the patient's heart rate can be obtained. By parsing the collected heart rate data, a sequence of heart rate values ​​can be obtained. By calculating the heart rate numerical sequence, the average value and fluctuation range of the patient's heart rate can be obtained. Generally, the normal heart rate of an adult is 60-100 beats / minute, and this range can be set as the preset normal heart rate range. At the same time, a threshold value for heart rate fluctuation is set, such as 20 beats / minute. If the calculated heart rate average value does not fall within the range of 60-100 beats / minute, or the heart rate fluctuation range exceeds 20 beats / minute, it is determined that the patient's heart rate is abnormal. In the case of abnormal heart rate, the transparent touch screen can display abnormal heart rate warning information, such as a red prompt of "The patient's heart rate is too fast, please pay attention", reminding the medical staff in the CT room to pay close attention to the patient's condition and terminate the scan if necessary. Finally, when it is monitored that the patient's posture does not meet the requirements or the heart rate is abnormal, it is necessary to determine the specific body part where the abnormality occurs so as to take targeted countermeasures. According to the posture data, it can be analyzed whether the patient's head, trunk or limbs have moved significantly. For example, by analyzing the change in the head position coordinates, if the change exceeds 10cm, it can be determined that the head movement is abnormal. Based on the heart rate data, the time point when the abnormal heart rate occurs can be determined. Combined with the posture data at that time point, the correlation between the abnormal heart rate and body movement can be inferred. For example, when the abnormal heart rate occurs, the posture data shows that the abdomen moves, which may be caused by breathing. The heart rate change. Based on the above analysis, the transparent touch screen can generate corresponding abnormal part images, such as marking the abnormally moving head in red on the human model image, and marking the abdominal position related to the abnormal heart rate in yellow, intuitively prompting medical staff to take corresponding measures, such as fixing the head and requiring breath holding.The transparent touch screen collects the patient's posture and heart rate data in real time, and performs intelligent analysis and judgment. It can promptly detect abnormal changes in the patient's posture and heart rate during the CT scan, and intuitively prompt medical staff by generating images of abnormal parts, thereby effectively ensuring the quality of CT images and the safety of patients, and improving the efficiency and level of CT examinations.

The CT inspection method based on the transparent touch display screen and the identification code according to claim 6, characterized in that: If the confirmation operation is recognized, the movement parameters of the CT device are set according to the basic information of the patient and the scanning protocol information, and the CT device is controlled to automatically position and scan the patient, including: If a confirmation operation is recognized, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso contour; Determine an optimal scanning position according to the patient's trunk contour and basic information of the patient, and use the optimal scanning position as the target position of the CT device; Acquire a CT device movement parameter according to the scanning protocol information, set the CT device movement parameter based on a target position of the CT device, and control the CT device to automatically move to the target position based on the set CT device movement parameter to complete the automatic positioning process of the patient; The scanning parameters are determined according to the scanning protocol information, and the scanning parameters are sent to the CT device, and the CT device is controlled to scan the patient according to the scanning parameters, thereby completing the automatic scanning process of the patient.

9. The CT inspection method based on the transparent touch display screen and the identification code according to claim 6, characterized in that: After controlling the CT device to automatically position and scan the patient, the method further includes: During the CT scanning process, the patient's posture data and heart rate data are obtained through the wearable device, and the patient's posture data and heart rate data are transmitted to the transparent touch display screen; The patient posture data and heart rate data received by the transparent touch display screen are used to determine whether the patient posture change value exceeds the preset change threshold and whether the heart rate exceeds the preset heart rate range. If the patient posture change value exceeds the preset change threshold or the heart rate exceeds the preset heart rate range, an abnormal part image is generated through the transparent touch display screen.

10. The CT inspection method based on the transparent touch display screen and the identification code according to claim 9, characterized in that: The patient posture data and heart rate data received by the transparent touch display screen determine whether the patient posture change value exceeds a preset change threshold value, and whether the heart rate exceeds a preset heart rate range. If the patient posture change value exceeds the preset change threshold value or the heart rate exceeds the preset heart rate range, an abnormal part image is generated by the transparent touch display screen, including: The patient posture data collected continuously by the transparent touch screen is compared to calculate the posture change value. If the posture change value exceeds the preset change threshold, it is determined that the patient's current posture does not meet the requirements of CT scanning, and prompt information is displayed on the transparent touch screen to guide the patient to adjust the posture; Parsing the patient's heart rate data received by the transparent touch display screen to obtain a heart rate value sequence, calculating the patient's heart rate average value and fluctuation range through the heart rate value sequence, judging whether the heart rate average value falls within a preset heart rate normal range, and judging whether the heart rate fluctuation range exceeds a preset heart rate fluctuation threshold; If the heart rate average value does not fall within the preset normal heart rate range or the heart rate fluctuation exceeds the preset heart rate fluctuation threshold, the patient's heart rate is determined to be abnormal, and an abnormal heart rate warning message is displayed on the transparent touch screen to remind medical staff to pay attention to the patient's condition; The body part where the abnormality occurs is determined based on the posture data of the patient that does not meet the CT scanning requirements and the heart rate data of the patient with abnormal heart rate, and an image of the abnormal part is generated through a transparent touch display based on the body part where the abnormality occurs.
