[0002] A core technical challenge in CT scans is how to improve automation and intelligence while ensuring examination quality and patient safety. This issue involves multiple aspects: First, accurate acquisition and effective utilization of patient information are fundamental, but traditional methods are prone to errors and inefficient. Second, adjustments to CT equipment parameters often rely on human experience, making precision and personalization difficult. Third, the lack of real-time monitoring and timely response mechanisms for patient status increases safety risks. Furthermore, the presentation of examination information is not intuitive enough, affecting the operational efficiency of medical staff. These interconnected problems collectively constrain the efficiency and safety of CT scans. Solving this technical challenge requires innovation and breakthroughs in multiple areas, including patient information management, intelligent equipment control, real-time monitoring and early warning, and information visualization. Simultaneously, it's crucial to consider how to organically integrate these technologies to build a coordinated and consistent intelligent CT scan system, achieving comprehensive optimization and upgrading of the examination process. This involves not only improvements to individual technologies but also systemic innovative thinking to address the complex challenges of CT scans. Summary of the Invention
[0003] This invention provides a CT examination system based on a transparent touch screen and identification codes, the system comprising a wearable device, a scanning device, and a transparent touch screen;
[0004] The wearable device generates an identification code containing basic patient information and scanning protocol information based on the patient's examination items;
[0005] The scanning device scans the identification code on the wearable device to obtain the patient's basic information and scanning protocol information, and transmits the patient's basic information and scanning protocol information to the transparent touch screen on the lead glass window between the CT scanning room and the control room.
[0006] The transparent touch screen displays the patient's basic information, scanning protocol information, and a confirmation button.

[0016] Furthermore, the wearable device is also used to acquire patient posture data and heart rate data during CT scans, and transmit the patient posture data and heart rate data to a transparent touch display screen;
[0017] 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 image of the abnormal part is generated through the transparent touch display screen.
[0018] Furthermore, the transparent touch display screen is also used for:
[0019] The system compares continuously collected patient posture data and calculates posture change values. If the posture change value exceeds a preset change threshold, it determines that the patient's current posture does not meet the requirements of CT scan. The system then displays prompt information on a transparent touch screen to guide the patient to adjust their posture.
[0020] The received patient heart rate data is parsed to obtain a heart rate value sequence. The patient's average heart rate and fluctuation range are calculated from the heart rate value sequence. It is determined whether the average heart rate falls within the preset normal heart rate range and whether the heart rate fluctuation range exceeds the preset heart rate fluctuation threshold.
[0021] If the average heart rate 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 a heart rate abnormality warning message is displayed to remind medical staff to pay attention to the patient's condition.
[0022] Based on the patient's posture data that does not meet the requirements for CT scan and the heart rate data of patients with abnormal heart rate, the body parts where the abnormality occurs are identified, and images of the abnormal body parts are generated based on the abnormal body parts.
[0023] Furthermore, to achieve the above objectives, the present invention also provides a CT examination method based on a transparent touch display screen and identification codes, the method being applied to the CT examination system based on a transparent touch display screen and identification codes as described above, the method comprising:
[0024] Based on the patient's examination items, an identification code containing the patient's basic information and scanning protocol information is generated and stored in the wearable device;
[0025] The patient's basic information and scanning protocol information are obtained by scanning the identification code on the wearable device, and then transmitted to the transparent touch screen on the lead glass window between the CT scanning room and the control room.
[0026] The transparent touch screen displays the patient's basic information, scanning protocol information, and confirmation operation button. If a confirmation operation is detected, the CT equipment's movement parameters are set according to the patient's basic information and scanning protocol information, and the CT equipment is controlled to automatically position and scan the patient.
[0027] Furthermore, the method of displaying basic patient information, scanning protocol information, and confirmation operation buttons via a transparent touchscreen display includes:
[0028] The size and resolution of the display area of the transparent touch screen are obtained, and the information layout scheme of the patient's basic information and scanning protocol information is determined based on the size and resolution of the display area.

[0030] Based on the aforementioned information layout scheme, the aforementioned human-computer interaction design principles, and the transparent display technology, the patient's basic information, scanning protocol information, and confirmation operation button are displayed. The transparent display technology is used to overlay the patient's basic information, scanning protocol information, and confirmation operation button onto the surface of a transparent touch screen without affecting the medical staff's line of sight.
[0031] Furthermore, if a confirmation operation is detected, the CT equipment movement parameters are set according to the patient's basic information and scanning protocol information to control the CT equipment to automatically position and scan the patient, including:
[0032] If a confirmation operation is detected, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso outline;
[0033] The optimal scanning position is determined based on the patient's torso contour and basic patient information, and the optimal scanning position is used as the target position of the CT equipment.
[0034] The CT equipment movement parameters are obtained according to the scanning protocol information. The CT equipment movement parameters are set based on the target position of the CT equipment. The CT equipment is controlled to automatically move to the target position based on the set CT equipment movement parameters to complete the automatic patient positioning process.
[0035] The scanning parameters are determined based on the scanning protocol information and sent to the CT equipment. The CT equipment is then controlled to scan the patient according to the scanning parameters, thus completing the automatic scanning process for the patient.
[0036] Furthermore, after the CT equipment automatically positions and scans the patient, it also includes:
[0037] During a CT scan, patient posture and heart rate data are acquired through a wearable device and then transmitted to a transparent touchscreen display.
[0038] The system uses patient posture and heart rate data received through a transparent touchscreen to determine whether the patient's posture changes exceed a preset threshold or the heart rate exceeds a preset range. If the patient's posture changes exceed the preset threshold or the heart rate exceeds the preset range, an image of the abnormal area is generated through the transparent touchscreen.
[0039] Furthermore, the process of determining whether the patient's posture change value exceeds a preset threshold and whether the heart rate exceeds a preset heart rate range based on the patient posture data and heart rate data received through the transparent touch display screen, and generating an image of the abnormal area through the transparent touch display screen if the patient's posture change value exceeds the preset threshold or the heart rate exceeds the preset heart rate range, includes:
[0040] The patient's posture data is continuously collected by the transparent touch screen and 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 scan. The transparent touch screen displays a prompt message to guide the patient to adjust their posture.
[0041] The patient's heart rate data received by the transparent touch screen is parsed to obtain a heart rate value sequence. The average heart rate and fluctuation range of the patient are calculated through the heart rate value sequence. It is determined whether the average heart rate falls within the preset normal heart rate range and whether the heart rate fluctuation range exceeds the preset heart rate fluctuation threshold.
[0042] If the average heart rate 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 a heart rate abnormality warning message is displayed on the transparent touch screen to remind medical staff to pay attention to the patient's condition.
[0043] Based on the patient's posture data that does not meet the requirements for CT scan and the patient's heart rate data that is abnormal, the body part where the abnormality occurs is determined, and an image of the abnormal body part is generated on a transparent touch screen.

[0046] Figure 1 This is a schematic diagram of a CT examination system based on a transparent touch screen and identification code according to the present invention.
[0047] Figure 2This is a flowchart of a CT examination method based on a transparent touch screen and identification code according to the present invention. Detailed Implementation
[0048] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] like Figure 1 This embodiment of a CT examination system based on a transparent touch screen and identification code may specifically include a wearable device, a scanning device, and a transparent touch screen;
[0050] The wearable device generates an identification code containing basic patient information and scanning protocol information based on the patient's 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, and gender, as well as the scanning protocol information for the examination, such as the scan area, scan range, slice thickness, and scan time. Before the examination, medical staff will generate a corresponding scanning protocol in the hospital information system based on 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, installed at the entrance of the CT examination room. When the patient enters the examination room, the scanner automatically scans the QR code on the patient's wristband, reads the patient information and scanning protocol information contained therein, and transmits this information to the CT equipment's control system. Based on the received scanning protocol information, the control system automatically adjusts the CT equipment's scanning parameters, such as slice thickness and scan time, without requiring manual settings by the physician, thus improving examination efficiency. Simultaneously, the control system will also automatically adjust the position of the examination bed based on the scan area information, aligning the patient's scan area with the scan center, achieving automatic positioning and further improving examination efficiency. The transparent touchscreen display is mounted on the lead glass observation window of the CT room. The lead glass window isolates the radiation emitted by the CT equipment, protecting staff from radiation. By mounting the touchscreen on the lead glass, physicians can observe the patient's condition through the display and simultaneously control the CT equipment via touch, eliminating the need to move back and forth between the control panel and the lead glass, thus improving operational efficiency. The touchscreen display is made of transparent material, remaining transparent under normal conditions for direct patient observation; when operation is required, electrochromic technology adjusts the display to opaque, showing the operating interface. This design saves space in the CT room and improves physician productivity.
[0052] The scanning device scans the identification code on the wearable device to obtain the patient's basic information and scanning protocol information, and then transmits the patient's basic information and scanning protocol information to a transparent touch screen on the lead glass window between the CT scanning room and the control room.
[0053] The scanning device can be a QR code scanner, capable of quickly recognizing and decoding QR code identifiers on wearable devices. The QR code contains basic patient information, such as name, age, and gender, as well as the scanning protocol for this CT scan, including parameters such as the scan area, slice thickness, and scan time. The scanner scans the QR code using infrared or visible light, converting the optical signal into a digital signal, and then uses a decoding algorithm to reconstruct the text information contained in the QR code. After acquiring the patient information and scanning protocol, the scanner transmits this data to a transparent touchscreen display between the CT room and the control room via wired or wireless network. The transparent touchscreen display uses transparent conductive film technology, ensuring both image clarity and touch interaction. Embedded within a leaded glass window, the display allows doctors to directly observe the patient's condition within the CT room without having to move between different display devices, improving work efficiency. The patient's basic information, including the patient's photo, name, age, gender, and medical record number, is clearly displayed on the transparent touchscreen interface, facilitating verification by the doctor. Simultaneously, various parameters of the scanning protocol are displayed, such as scanning mode, tube voltage / current, collimation width, scanning time, and reconstruction algorithm, allowing doctors to review and fine-tune as needed. A "Start Scan" button is also present on the interface. After confirming that all parameters are correct, doctors can directly start the scanning program via the touchscreen, simplifying cumbersome operation steps. This design, which integrates patient information and scanning plans onto a wearable device's QR code, combined with the use of a transparent touchscreen in the CT room, significantly improves the automation and intelligence of CT examinations. Traditional methods of manually entering information and setting parameters are prone to errors and inefficient. Using QR codes for automatic data collection and transmission reduces human error and ensures information accuracy. Furthermore, the transparent touchscreen integrates display and control functions, streamlining information flow and optimizing the doctor's operating experience and workflow.
[0054] The transparent touch screen displays the patient's basic information, scanning protocol information, and a confirmation button. If a confirmation operation is detected, the CT equipment's movement parameters are set according to the patient's basic information and scanning protocol information, and the CT equipment is controlled to automatically position and scan the patient.
[0055] The transparent touchscreen display shows basic patient information such as name, age, gender, and medical record number, facilitating quick patient identification by physicians. Simultaneously, it displays the scanning protocol information for the current CT scan, including parameters such as scan site, scan range, slice thickness, and scan time. Physicians can adjust and optimize the scanning protocol via touch to meet the needs of different patients and examinations. After confirming the patient information and scanning protocol are correct, a confirmation button pops up on the transparent touchscreen. Upon clicking the confirmation button, the CT control system automatically calculates the optimal CT equipment movement parameters based on the patient's height, weight, and other basic information, combined with the parameters set in the scanning protocol. These parameters include the height of the scanning bed, the speed of the scanning bed, the rotation speed of the X-ray tube, and the exposure time. This automatic setting of movement parameters ensures the patient maintains the most comfortable position during the scan and minimizes artifacts caused by positional changes. Furthermore, the optimized scanning parameters minimize the radiation dose received by the patient while maintaining image quality. After parameter settings are completed, the CT control system automatically positions the patient within the CT equipment. First, the scanning bed automatically moves to the height most suitable for the patient's height and gently guides the patient into the center of the X-ray tube. Simultaneously, the laser positioning system projects a crosshair, helping the physician determine if the patient is centered on the scan. The CT scanner is also equipped with a high-precision three-dimensional surface scanning system that tracks the patient's body contour in real time and fine-tunes the patient's position based on the anatomical features of the scanned area, ensuring it is perfectly parallel to the scanning plane. This automated positioning standardizes the scanning procedure, improves examination efficiency, and avoids errors caused by manual positioning. Once the patient is positioned, the CT control system automatically starts the scanning program according to the scanning protocol. During the scan, the system monitors parameters such as X-ray tube current and voltage in real time and dynamically adjusts the exposure dose based on the patient's body size and absorption differences of the scanned area to obtain optimal image quality. Simultaneously, the system monitors and compensates for the patient's physiological movements (such as breathing and heartbeat) in real time, minimizing motion artifacts by adjusting the data acquisition time window. The entire scanning process is highly automated; the physician only needs to observe the patient's status through a transparent touchscreen, eliminating the need for manual parameter adjustments and significantly reducing operational difficulty and the risk of error. After the scan is complete, the CT scanner automatically removes the patient from the scanning tube and resets the scanning bed. Simultaneously, the scanned images are automatically transferred to the image post-processing workstation for image reconstruction and post-processing. Physicians can view the reconstruction progress and image quality in real time via a transparent touchscreen and adjust the reconstruction algorithm and parameters as needed. This real-time interactive image processing method helps physicians quickly obtain high-quality diagnostic images and reduces patient waiting time.
[0056] Furthermore, the transparent touch display screen is also used for:
[0057] The size and resolution of the display area of the transparent touch screen are obtained, and the information layout scheme of the patient's basic information and scanning protocol information is determined based on the size and resolution of the display area.
[0058] Adopting human-computer interaction design principles, a confirmation button is set in the touch operation area, which is preset according to the operating habits of medical staff;
[0059] Based on the aforementioned information layout scheme, the aforementioned human-computer interaction design principles, and the transparent display technology, the patient's basic information, scanning protocol information, and confirmation operation button are displayed. The transparent display technology is used to overlay the patient's basic information, scanning protocol information, and confirmation operation button onto the surface of a transparent touch screen without affecting the medical staff's line of sight.
[0060] To determine the optimal layout of patient basic information and scanning protocol information on the transparent touchscreen display, the system first needs to obtain the display area size and resolution of the transparent touchscreen display. For example, if the display area of the transparent touchscreen display is 21.5 inches and the resolution is 1920x1080, the system can design the optimal information layout based on these parameters. Specifically, the system can divide the display area into different functional areas, such as a patient basic information area, a scanning protocol information area, and a 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 to ensure the clarity and readability of the information. At the same time, the layout scheme also needs to take into account the usage habits and workflows of medical staff, making their operation more convenient and efficient. For example, the patient basic information area can be placed in the upper left corner of the display, the scanning protocol information area in the upper right corner, and the touch operation area at the bottom. This layout conforms to people's reading habits and makes it easier for medical staff to quickly find the information they need. When designing the touch operation area of the transparent touchscreen display, human-computer interaction design principles need to be fully considered to improve the operating efficiency and accuracy of medical staff. Based on the operating habits of medical staff, some commonly used operation buttons, such as "Confirm," "Cancel," and "Pause," 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 operations quickly and accurately. For example, the "Confirm" button can be green, located in the center of the touch operation area, and its size should be large enough for easy clicking. At the same time, the spacing between buttons also needs to be reasonably set to avoid accidental operation. Furthermore, the layout and function of the buttons in the touch operation area can be dynamically adjusted according to different operating scenarios to adapt to the actual needs of medical staff. For example, during scanning, the "Pause" button can be placed in a more prominent position so that medical staff can quickly pause the scan when needed. To clearly display patient basic information, scanning protocol information, and confirmation operation buttons on the transparent touch display screen without obstructing the medical staff's view, transparent display technology is required. Transparent display technology can overlay image information onto the surface of the transparent touch display screen, making it appear as if it is floating in mid-air, without obstructing the medical staff's view. Meanwhile, transparent display technology can automatically adjust the brightness and contrast of the screen according to changes in ambient light to ensure that image information remains clearly visible under all conditions. In practical applications, transparent touch displays can use different transparency settings depending on the content being displayed. 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 buttons, the transparency can be set lower to avoid interfering with the vision of medical staff.Meanwhile, transparent touchscreen displays can also utilize various visual elements such as color, font, and animation to attract the attention of medical staff and improve their enthusiasm and accuracy in operation. For example, in the patient's basic information area, bright colors and larger font sizes can be used to highlight important information; in the scanning protocol information area, icons and animations can be used to intuitively demonstrate the scanning process; and eye-catching prompts or symbols can be added to the confirmation button to guide medical staff in their operations.
[0061] Furthermore, the transparent touch display screen is also used for:
[0062] If a confirmation operation is detected, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso outline;
[0063] The optimal scanning position is determined based on the patient's torso contour and basic patient information, and the optimal scanning position is used as the target position of the CT equipment.
[0064] The CT equipment movement parameters are obtained according to the scanning protocol information. The CT equipment movement parameters are set based on the target position of the CT equipment. The CT equipment is controlled to automatically move to the target position based on the set CT equipment movement parameters to complete the automatic patient positioning process.
[0065] The scanning parameters are determined based on the scanning protocol information and sent to the CT equipment. The CT equipment is then controlled to scan the patient according to the scanning parameters, thus completing the automatic scanning process for the patient.
[0066] If a confirmation operation is detected, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso contour. Image segmentation refers to the technique and process of dividing an image into several specific regions with unique properties and extracting the target of interest. For patient images in CT scans, a region growing-based segmentation algorithm can be used. This algorithm uses the grayscale, texture, and other features of the patient's torso region as growth criteria. Starting from a selected seed point, it gradually merges pixels in the neighborhood that meet the growth criteria into the seed region until no more pixels that meet the conditions can be included, thus completing the segmentation of the entire torso region and obtaining a clear torso contour. The optimal scanning position is determined based on the patient's torso contour and basic patient information, and this optimal scanning position is used as the target position for the CT equipment. The optimal scanning position for the patient needs to comprehensively consider the patient's height, weight, and other basic information, as well as the torso contour features. For example, for a chest CT scan, the patient's lungs need to be placed in the optimal position of the scanning beam. By analyzing the patient's torso contour data, the three-dimensional spatial coordinates of the lung region can be obtained. Combined with the patient's height and weight information, the displacement that the CT scanning table needs to move can be calculated, thereby moving the patient's lungs to the optimal scanning position. This location is the target scanning position for the CT scanner. The CT scanner's movement parameters are obtained based on the scanning protocol information. These parameters are then set based on the target position, and the CT scanner is automatically moved to the target position, completing the automatic patient positioning process. The scanning protocol information includes various technical parameters of the CT scanner, such as scanning mode, tube voltage, tube current, and slice thickness. It should also include movement parameters, such as movement speed and acceleration. Based on the target position determined in the previous step, the distance and direction the CT scanner needs to move can be calculated. Then, based on the movement parameters, the CT scanner's moving motor is controlled to move at a specific speed and acceleration until the CT scanner reaches the target position and stops, thus completing the automatic patient positioning process. The entire positioning process requires no manual intervention, improving work efficiency. Alternatively, the scanning parameters are determined based on the scanning protocol information and sent to the CT scanner. The CT scanner is then controlled to scan the patient according to these parameters, completing the automatic patient scanning process. The scanning protocol information includes a series of scanning parameters, such as scanning mode, tube voltage, tube current, slice thickness, pitch, and scanning time. The appropriate combination of scanning parameters can be selected based on the patient's specific examination needs, such as conventional CT, high-resolution CT, or low-dose CT. Once the scanning parameters are determined, they are sent to the CT equipment's control system. The CT control system automatically adjusts the X-ray tube's operating status based on the received parameters, while simultaneously controlling the CT scanning table to perform helical or axial scanning at a specific speed, and concurrently acquiring image data.The entire scanning process is automated. Once the scan is complete, the CT equipment automatically stops and transmits the acquired image data to the image workstation for subsequent image reconstruction processing to obtain the final CT image, thus completing the automated scanning process for the patient.
[0067] Furthermore, the wearable device is also used to acquire patient posture data and heart rate data during CT scanning, and transmit the patient posture data and heart rate data to a 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 image of the abnormal part is generated through the transparent touch display screen.
[0069] Wearable devices acquire patient posture and heart rate data and transmit it to a transparent touchscreen display. This process can be achieved by embedding posture and heart rate sensors within the wearable device. Posture sensors, such as accelerometers and gyroscopes, detect changes in the angles of different parts of the patient's body to determine posture changes. Heart rate sensors measure the patient's heart rate using methods such as photoplethysmography. The wearable device collects the patient's posture and heart rate data in real time and transmits the data to the transparent touchscreen display via a wireless communication module (such as Bluetooth or WiFi). Upon receiving the patient's posture and heart rate data, the transparent touchscreen display needs to process and evaluate the data. First, a posture change threshold and a normal heart rate range must be set. The posture change threshold can be set based on the requirements for patient posture stability in CT scans; for example, the angle changes of the patient's head, torso, and limbs should not exceed 5 degrees. The normal heart rate range can be set based on factors such as the patient's age and gender; generally, a normal heart rate for adults is 60-100 beats per minute. The control system of the transparent touchscreen 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. Simultaneously, it determines whether the patient's heart rate is within the normal range. If the patient's posture changes exceed a preset threshold or the heart rate exceeds the normal range, the transparent touchscreen display will generate images of the abnormal areas. For example, if a significant change in the patient's head posture is detected, a 3D model image of the head can be displayed on the screen, with the head area highlighted in red to alert the doctor. If the patient's heart rate is too fast or too slow, an electrocardiogram can be displayed on the screen, marking the abnormal heart rate intervals. Images of abnormal areas can help doctors quickly locate problems and adjust the scanning plan or intervene in the patient in a timely manner. The transparent touchscreen display can also issue audible and visual alarms to alert both the doctor and the patient. By monitoring the patient's posture and heart rate in real time through wearable devices, combined with the intelligent judgment and abnormality alert functions of the transparent touchscreen display, the safety and effectiveness of the CT scan process can be ensured. On the one hand, it can avoid image artifacts and duplicate scans caused by changes in patient posture; on the other hand, it can prevent unexpected situations caused by abnormal heart rates. This real-time monitoring and intelligent alert function is particularly important for special patient groups such as the elderly and children, helping to reduce medical errors such as missed diagnoses and misdiagnoses. Meanwhile, through visualized images of abnormal areas, doctors can gain a more intuitive understanding of the patient's condition, improving the efficiency of diagnosis and decision-making. In short, the combined application of wearable devices and transparent touchscreen displays can enhance the intelligence level of CT scans and ensure medical quality and safety.
[0070] Furthermore, the transparent touch display screen is also used for:
[0071] The system compares continuously collected patient posture data and calculates posture change values. If the posture change value exceeds a preset change threshold, it determines that the patient's current posture does not meet the requirements of CT scan. The system then displays prompt information on a transparent touch screen to guide the patient to adjust their posture.
[0072] The received patient heart rate data is parsed to obtain a heart rate value sequence. The patient's average heart rate and fluctuation range are calculated from the heart rate value sequence. It is determined whether the average heart rate falls within the preset normal heart rate range and whether the heart rate fluctuation range exceeds the preset heart rate fluctuation threshold.
[0073] If the average heart rate 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 a heart rate abnormality warning message is displayed to remind medical staff to pay attention to the patient's condition.
[0074] Based on the patient's posture data that does not meet the requirements for CT scan and the heart rate data of patients with abnormal heart rate, the body parts where the abnormality occurs are identified, and images of the abnormal body parts are generated based on the abnormal body parts.
[0075] The transparent touchscreen display can monitor changes in patient posture in real time. It collects patient posture data through sensors and compares it with preset standard posture data. Specifically, it uses an infrared depth camera to collect the patient's three-dimensional posture information, extracts the coordinates of key skeletal points, calculates the angles of each joint, and obtains a data vector describing the patient's current posture. This vector is then compared to the preset standard posture vector using Euclidean distance calculation to obtain a posture change value. If this value exceeds a preset threshold (e.g., 10°), the patient's current posture is deemed incorrect. At this point, a human body model is displayed on the transparent touchscreen, highlighting the incorrect posture in red, and providing corresponding voice prompts, such as "Please keep your head still" and "Please lie flat with your legs together," guiding the patient to adjust to the correct scanning posture. Simultaneously, the transparent touchscreen can also display the patient's heart rate status in real time. By connecting a wireless ECG sensor, it collects the patient's ECG signal at a certain frequency (e.g., once per second) and transmits it to the control system for processing. The system performs noise filtering on the raw ECG signal, extracts the R-wave peak value, calculates the time interval RR between adjacent R waves, and then obtains the real-time heart rate using the formula HR = 60 / RR. The system arranges the heart rate values of the most recent minute in chronological order to form a heart rate sequence. The average of this sequence is calculated as the patient's average heart rate. The difference between the maximum and minimum values in the sequence is then calculated as the heart rate fluctuation range. The system presets a normal adult heart rate range, such as 60-100 beats per minute. If the patient's average heart rate exceeds this range, or the fluctuation range exceeds a certain threshold (e.g., 30 beats per minute), it is considered an abnormal heart rate. When an abnormal heart rate is detected, a red warning box pops up on the transparent touchscreen, displaying the patient's real-time electrocardiogram and heart rate values, and an alarm sounds to alert medical staff. The system also analyzes the cause of the abnormal heart rate. If it is found to be caused by changes in body position, the body parts that may affect the heart rate are marked on the screen, prompting the patient to adjust their position. If body position is ruled out, medical advice is displayed, such as "Please monitor closely and terminate the examination if necessary." Furthermore, the system can correlate and analyze the patient's posture data and heart rate data to determine the body part where the abnormality occurs. For example, if a patient's heart rate suddenly spikes while their left leg posture deviates from the standard range, it's suspected that discomfort in the left leg is causing the abnormal heart rate. In this case, a human image is displayed on the transparent screen, highlighting the left leg in red to alert the doctor. If the posture and heart rate abnormalities persist for a period, a CT scan image of the left leg is overlaid on the human image, visually demonstrating the anatomical structure of the abnormal area and providing the doctor with more clues to determine the cause. Through this method, the transparent touchscreen display can achieve intelligent monitoring of the patient's condition throughout the entire process, providing timely warnings and intuitive visual cues to ensure patient safety. It also provides medical staff with richer information for diagnostic decisions, helping to improve the efficiency and accuracy of CT scans.This human-computer interaction method breaks down the barriers to information transmission in traditional CT rooms, achieving seamless connection and real-time interaction between patients, equipment, and doctors, representing a more intelligent and humanized new model of diagnosis and treatment.
[0076] In addition, refer to Figure 2 The present invention also provides a CT examination method based on a transparent touch screen and identification code, the method being applied to the CT examination system based on a transparent touch screen and identification code as described above, the method comprising:
[0077] S101. Generate an identification code containing basic patient information and scanning protocol information based on the patient's examination items, and store the identification code in the wearable device;
[0078] S102. Scan the identification code on the wearable device with the scanning device to obtain the patient's basic information and scanning protocol information, and transmit the patient's basic information and scanning protocol information to the transparent touch screen on the lead glass window between the CT scanning room and the control room.
[0079] S103. 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 equipment movement parameters are set according to the patient's basic information and scanning protocol information, and the CT equipment is controlled to automatically position and scan the patient.
[0080] An identification code containing basic patient information and scanning protocol information is generated based on the patient's examination items and stored in a wearable device. For example, when a patient needs a head CT scan, 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 the head scan parameters such as tube voltage 120kV, tube current 200mA, scan slice thickness 5mm, and scan range from above the orbitoauricular line to below the external occipital protuberance. This identification code can be encrypted using algorithms such as AES or RSA to ensure the security of patient information. The generated identification code can be stored in a wearable device such as a wristband or card worn by the patient for easy carrying by the patient and reading by CT room staff. 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 then transmitted to a transparent touch screen on a lead-glass window between the CT scanning room and the control room. When the patient enters the CT room, CT room staff can use a dedicated scanning device such as a barcode scanner to scan and identify the identification code on the patient's wearable device. The scanning device decodes the identification code using a decoding algorithm to obtain the patient's basic information and the scanning protocol for this examination. To ensure scanning efficiency and accuracy, the scanning device can employ a high-speed, high-precision scanning module, such as a CCD or CMOS sensor. The acquired patient information and scanning protocol can be transmitted via wired network or wireless WiFi to a transparent touchscreen display at the lead glass window between the CT room and the control room for physician verification and confirmation. Encrypted communication protocols, such as SSL / TLS, should be used during transmission to prevent information leakage. The transparent touchscreen display shows the patient's basic information, scanning protocol information, and a confirmation button. If a confirmation operation is detected, the CT equipment's movement parameters are set according to the patient's basic information and scanning protocol information, controlling the CT equipment to automatically position and scan the patient. After receiving the patient information and scanning protocol, the transparent touchscreen display clearly displays key information such as patient name, ID, age, examination items, position, scanning range, tube voltage, and tube current in a prominent position on the screen, while simultaneously displaying a "Confirm to Start Examination" button at the bottom of the screen. The on-duty physician can clearly see the patient's properly positioned state through the lead glass, and simultaneously verify the patient information and scanning protocol on the transparent screen. After confirming that everything is correct, they click the "Confirm to Start Examination" button. The transparent touchscreen uses infrared touch technology, supports multi-touch, and offers precise positioning, allowing for easy operation even for physicians wearing gloves. Once the transparent screen detects the physician's confirmation, it sends the patient information and scanning protocol parameters to the CT equipment. Based on the received parameters, the CT equipment automatically adjusts the height and position of the CT bed, moving the scanning area, such as the head, to the scanning center; simultaneously, it sets the X-ray tube parameters and collimator, strictly adhering to the scanning protocol, such as a slice thickness of 5mm and a tube voltage of 120kV. The CT equipment can use a servo motor to precisely control the bed's movement, ensuring accurate patient positioning.The entire positioning and scanning process is automated, eliminating the need for manual operation by physicians. This avoids errors and inefficiencies associated with manual operation and improves the standardization and intelligence of the examination.
[0081] Furthermore, the method of displaying basic patient information, scanning protocol information, and confirmation operation buttons via a transparent touchscreen display includes:
[0082] The size and resolution of the display area of the transparent touch screen are obtained, and the information layout scheme of the patient's basic information and scanning protocol information is determined based on the size and resolution of the display area.
[0083] Adopting human-computer interaction design principles, a confirmation button is set in the touch operation area, which is preset according to the operating habits of medical staff;
[0084] Based on the aforementioned information layout scheme, the aforementioned human-computer interaction design principles, and the transparent display technology, the patient's basic information, scanning protocol information, and confirmation operation button are displayed. The transparent display technology is used to overlay the patient's basic information, scanning protocol information, and confirmation operation button onto the surface of a transparent touch screen without affecting the medical staff's line of sight.
[0085] Obtaining the display area size and resolution of the transparent touchscreen display is fundamental to designing the information layout. Assuming the transparent touchscreen display is 60 inches in size with a resolution of 3840×2160 pixels (4K resolution), the screen can first be divided into multiple functional areas based on the size and resolution of the display area. For example, the upper part of the screen can be used to display basic patient information, such as name, age, gender, and examination items; the middle part can display scanning protocol information, such as slice thickness, interslice spacing, and scan time; and the bottom can be reserved as a touch operation area with a "confirm" button. In a specific layout, the upper patient information area can occupy 20% of the screen, the middle scanning protocol information area 50%, and the bottom touch operation area 30%. This layout ensures clear information display while facilitating operation by medical staff. When setting the confirmation button in the touch operation area using human-computer interaction design principles, the operating habits and visual focus of medical staff must be considered. Based on ergonomic principles, the confirmation button should be positioned at the bottom center of the screen, measuring 100×100 pixels, and painted a striking green to facilitate quick location and operation by medical staff while observing the patient. Sufficient blank space should be left around the button to prevent accidental touches. To further optimize the user experience, the button can also be designed with slight vibration feedback to ensure clear tactile feedback for medical staff. Based on information layout schemes and human-computer interaction design principles, transparent display technology is used to overlay basic patient information, scanning protocol information, and the confirmation button onto the surface of the transparent touchscreen display. Transparent display technology, achieved through optical coating and LED backlighting, clearly displays information without obstructing the medical staff's view. For example, when medical staff observe a patient through the transparent screen, the patient's basic information and scanning protocol information will be superimposed on the patient in a semi-transparent manner, providing necessary information support without hindering observation. The confirmation button is highlighted to ensure visibility even in complex environments. In practice, the display effect of the transparent touchscreen display can be optimized by adjusting transparency and contrast. Assuming transparency is set to 70% and contrast to 80%, this design ensures both information visibility and allows medical staff to clearly observe the patient's condition. Furthermore, the screen brightness automatically adjusts according to ambient light, ensuring optimal display performance under varying lighting conditions. This design not only saves space but also improves operational convenience and safety. For example, in emergencies, medical staff can complete all operations directly on the transparent screen without turning around to operate the control panel, significantly reducing response time. Simultaneously, the rational information layout and ergonomically designed operation buttons reduce the likelihood of errors during operation, improving scanning accuracy and efficiency.Furthermore, transparent touchscreen displays can integrate other auxiliary functions, such as real-time heart rate monitoring and respiratory rate display, further enriching the information access channels for medical staff. For example, during the scan, the upper right corner of the screen can display the patient's heart rate and respiratory rate in real time, helping medical staff to promptly grasp the patient's physiological state 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, transparent touchscreen displays play a vital role in the CT scanning process, not only optimizing the operation process but also improving scanning efficiency and safety, providing strong support for the construction and development of modern hospitals.
[0086] Furthermore, if a confirmation operation is detected, the CT equipment movement parameters are set according to the patient's basic information and scanning protocol information to control the CT equipment to automatically position and scan the patient, including:
[0087] If a confirmation operation is detected, the patient image is segmented using an image segmentation algorithm to obtain the patient's torso outline;
[0088] The optimal scanning position is determined based on the patient's torso contour and basic patient information, and the optimal scanning position is used as the target position of the CT equipment.
[0089] The CT equipment movement parameters are obtained according to the scanning protocol information. The CT equipment movement parameters are set based on the target position of the CT equipment. The CT equipment is controlled to automatically move to the target position based on the set CT equipment movement parameters to complete the automatic patient positioning process.
[0090] The scanning parameters are determined based on the scanning protocol information and sent to the CT equipment. The CT equipment is then controlled to scan the patient according to the scanning parameters, thus completing the automatic scanning process for the patient.
[0091] After the patient enters the CT room, a QR code on the patient's scanning protocol wristband is scanned using a QR code scanning device to obtain the patient's basic information and scanning protocol information. Once the physician confirms the patient is ready via a touch-sensitive transparent screen, the system recognizes the confirmation and begins the automatic positioning and scanning process. First, the system uses image segmentation algorithms from computer vision technology to segment the patient image acquired by the CT equipment. Common image segmentation algorithms include thresholding, region growing, and watershed segmentation. 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 patient's outer boundary. Next, the system comprehensively considers the patient's torso contour information and basic information, such as height and weight, to calculate the optimal position for this scan. The optimal scanning position refers to the position where the CT scanning table can obtain the most comprehensive and clear imaging of the target area. This position is usually located in the center of the target area and avoids tissues such as bones and gases that may affect image quality. The system sets the calculated optimal scanning position as the target position of the CT equipment. Based on the acquired scanning protocol information, the system can determine the necessary movement parameters for the CT scanner, such as direction, distance, and speed. Using the target position as a reference, the system sets the CT scanner's movement parameters and controls its automatic movement until the scanning bed reaches the target position. This process achieves automatic patient positioning, eliminating the need for manual adjustment by the physician and improving positioning accuracy and efficiency. After automatic positioning, the system determines the required parameters for the scan based on the scanning protocol information, such as scanning range, tube voltage, tube current, slice thickness, and pitch. These parameters directly affect the image quality and radiation dose. The system sends the optimized scanning parameters to the CT scanner, controlling it to scan according to the parameter settings to obtain tomographic images of the patient's target area. The entire scanning process is automated; the physician only needs to monitor the scan progress and image quality in real time via a touch-sensitive transparent screen. In summary, the automated CT scanning process based on the scanning protocol wristband and touch-sensitive transparent screen fully utilizes technologies such as computer vision and artificial intelligence to achieve fully automated control from patient positioning to image acquisition. Compared to traditional manual operation, this solution offers the following advantages: First, automatic positioning eliminates the tedious steps of manually adjusting patient position, improving examination efficiency. Second, parameter settings are automatically optimized by the system according to the scanning protocol, reducing human error and ensuring consistent image quality. Third, physicians can visually monitor the scanning process through a touch-sensitive transparent screen, making operation more intuitive and convenient. These advantages not only enhance the intelligence level of CT examinations but also provide patients with a higher quality and more efficient medical service experience.
[0092] Furthermore, after the CT device automatically positions and scans the patient, it also includes:
[0093] During a CT scan, patient posture and heart rate data are acquired through a wearable device and then transmitted to a transparent touchscreen display.
[0094] The system uses patient posture and heart rate data received through a transparent touchscreen to determine whether the patient's posture changes exceed a preset threshold or the heart rate exceeds a preset range. If the patient's posture changes exceed the preset threshold or the heart rate exceeds the preset range, an image of the abnormal area is generated through the transparent touchscreen.
[0095] During a CT scan, wearable devices worn by the patient acquire real-time posture and heart rate data. These devices, such as smart bracelets or smartwatches, are equipped with built-in accelerometers, gyroscopes, and heart rate sensors to collect patient posture and heart rate information. The acquired data is transmitted in real-time to a transparent touchscreen display in the CT room via wireless communication modules (such as Bluetooth or WiFi). The transparent touchscreen display runs specialized software that receives and processes the data from the wearable device. The software analyzes the received patient posture data, calculating the change in posture—the degree of deviation of the patient's current posture from the posture at the start of the scan. If the calculated change in posture exceeds a preset threshold (e.g., 5 degrees), it is considered a significant change in posture that may affect the quality of the scanned images. Simultaneously, the software also determines whether the patient's heart rate exceeds the normal range (e.g., the normal range for an adult heart rate is 60-100 beats per minute). When the software detects that a patient's posture change exceeds a threshold or that their heart rate is abnormal, it automatically processes and analyzes the acquired CT images, identifying areas where artifacts or contamination may exist. The abnormal areas are then displayed in real-time on a transparent touchscreen, alerting the doctor to potential scan problems. The abnormal area image can be overlaid on the original CT image, or it can be displayed separately as a segmented image, marked with a prominent color (e.g., red). This method allows for real-time monitoring of the patient's posture and physiological state during the CT scan, promptly alerting the doctor to any abnormalities. This avoids scan failures or image quality degradation caused by changes in patient position or abnormal heart rate, improving the success rate and efficiency of CT scans while reducing radiation dose and patient discomfort. This method leverages the advantages of wearable devices and transparent touchscreens, organically combining them with CT equipment to achieve intelligent and visualized scanning.
[0096] Further, the process involves determining whether the patient's posture change exceeds a preset threshold and whether the heart rate exceeds a preset range based on the patient posture data and heart rate data received via the transparent touchscreen display. If the patient's posture change exceeds the preset threshold or the heart rate exceeds the preset range, an image of the abnormal area is generated via the transparent touchscreen display, including:
[0097] The patient's posture data is continuously collected by the transparent touch screen and 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 scan. The transparent touch screen displays a prompt message to guide the patient to adjust their posture.
[0098] The patient's heart rate data received by the transparent touch screen is parsed to obtain a heart rate value sequence. The average heart rate and fluctuation range of the patient are calculated through the heart rate value sequence. It is determined whether the average heart rate falls within the preset normal heart rate range and whether the heart rate fluctuation range exceeds the preset heart rate fluctuation threshold.
[0099] If the average heart rate 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 a heart rate abnormality warning message is displayed on the transparent touch screen to remind medical staff to pay attention to the patient's condition.
[0100] Based on the patient's posture data that does not meet the requirements for CT scan and the patient's heart rate data that is abnormal, the body part where the abnormality occurs is determined, and an image of the abnormal body part is generated on a transparent touch screen.
[0101] During a CT scan, the patient's posture and heart rate are crucial factors affecting scan quality and safety. To monitor changes in patient posture and heart rate in real time, a transparent touchscreen display can be used to collect and analyze this data. First, the transparent touchscreen continuously collects patient posture data, such as the position and angle of the head, torso, and limbs. By comparing and analyzing the continuously collected posture data, the magnitude of the posture change can be calculated. A preset posture change threshold, such as 5 degrees, is set. If the calculated posture change exceeds 5 degrees, the patient's current posture is considered to have deviated from the initially set standard posture and no longer meets the requirements for a CT scan. In this case, the transparent touchscreen display can show appropriate prompts, such as "Please remain still and do not move," guiding the patient to adjust their posture and return to the correct scanning position. Second, the transparent touchscreen can also receive the patient's heart rate data in real time. By connecting to an electrocardiogram (ECG) monitor, continuous heart rate values can be obtained. Parsing the collected heart rate data yields a sequence of heart rate values. By calculating this heart rate sequence, the average heart rate and its fluctuation range can be obtained. Generally, a normal adult heart rate is 60-100 beats per minute, and this range can be set as the preset normal heart rate range. Simultaneously, a threshold for heart rate fluctuation can be set, such as 20 beats per minute. If the calculated average heart rate does not fall within the 60-100 beats per minute range, or if the heart rate fluctuation range exceeds 20 beats per minute, the patient's heart rate is considered abnormal. For abnormal heart rate situations, the transparent touchscreen display can show warning messages, such as a red "Patient's heart rate is too fast, please pay attention" prompt, reminding medical staff in the CT room to closely monitor the patient's condition and, if necessary, terminate the scan. Finally, when abnormal patient posture or heart rate is detected, it is necessary to determine the specific body part where the abnormality occurs in order to take targeted measures. Posture data can be analyzed to determine whether the patient's head, torso, or limbs are moving significantly. For example, by analyzing changes in head position coordinates, if the change exceeds 10 cm, it can be determined as abnormal head movement. Based on heart rate data, the timing of the heart rate abnormality can be determined. Combined with postural data at that time, the correlation between the abnormality and body movement can be inferred. For example, if postural data shows abdominal movement when a heart rate abnormality occurs, it may be due to respiratory movements causing the heart rate change. Based on this analysis, the transparent touchscreen display can generate images of the corresponding abnormal areas. For instance, on a human model image, the abnormally moving head can be marked in red, and the abdominal area related to the heart rate abnormality can be marked in yellow, visually prompting medical staff to take appropriate measures, such as stabilizing the head or instructing them to hold their breath.By collecting patients' posture and heart rate data in real time through a transparent touch screen and performing intelligent analysis and judgment, abnormal changes in patients' posture and heart rate can be detected in a timely manner during CT scans. The abnormal areas can be visually alerted to medical staff by generating images, thereby effectively ensuring the quality of CT images and the safety of patients, and improving the efficiency and level of CT examinations.
