Description

Technical Field

[0001] The present invention relates to the technical field of medical image scanning, and in particular to a real-time multi-dimensional information interaction system in a medical multi-dimensional information intelligent monitoring interaction system during an image scanning and inspection process. Background Art

[0002] The current medical image scanning process still has some limitations and shortcomings. During the scanning process, the operator's instructions can only be conveyed to the patient through voice broadcast. For patients with various hearing impairments, regional language and cultural differences, and the elderly and frail, the asymmetric communication information often makes it difficult to complete the corresponding scan or even causes the examination to fail.

[0003] Due to the particularity of medical examinations, even with an accompanying person, it is necessary to communicate and explain things to the patient multiple times. In addition, some medical examinations (such as PET-CT and CT scans) have ionizing radiation damage in the room, which makes it inconvenient for the accompanying person to stay with the patient.

[0004] Furthermore, it's difficult for patients to communicate with the operator in real time during the scan. If they experience any discomfort, such as an allergic reaction to the contrast agent, they can't provide prompt and accurate feedback to the operator. Prompt identification and proactive treatment of allergic reactions and discomfort are crucial for emergency response. Lack of timely communication between doctors and patients can lead to missed opportunities to address allergic reactions and sudden discomfort, further exacerbating the situation.

[0005] Furthermore, during the scanning process, the patient is often required to keep the scanned area still to ensure stable image quality. However, the current scanning process cannot detect whether the patient's scanned area remains still during the scanning process. The only way to determine whether the patient's scanned area has moved is to observe the scanned image after the imaging is completed. If there is movement and it affects the diagnosis, the scan must be repeated. This not only reduces workflow efficiency but also increases the patient's exposure to additional radiation. Summary of the Invention

[0006] The purpose of the technical solution of the present invention is to improve the efficiency of the scanning workflow, reduce the additional loss of patients exposed to radiation, and promptly detect sudden adverse reactions of patients to ensure life safety.

[0007] To achieve the above-mentioned purpose, the present invention provides a real-time multi-dimensional information interaction system for medical scans, which includes both subjective information interaction methods and objective physiological multi-dimensional information interaction schemes for patients. It includes a basic information detection module, a multi-dimensional instruction information transmission module, an information feedback and intelligent decision-making assistance module, and an information recording and integration module:

[0008] The basic information detection module obtains the patient's basic information, detects the patient's physiological information based on the patient's basic information and records it, and organizes and analyzes it in combination with the patient's basic information as known medical data;

[0009] The multi-dimensional instruction information transmission module retrieves the patient's basic information and the patient's physiological basic information from the basic information detection module, and generates instruction voice, body demonstration movements and colored flashing eye-catching text according to the patient's basic information and the patient's physiological basic information to issue instructions;

[0010] The physiological information detection module obtains the patient's physiological information generated when the patient executes the instructions;

[0011] The information feedback and intelligent decision-making support module obtains the patient's physiological information from the physiological information detection module and the patient's basic information, patient physiological basic information and instructions from the multi-dimensional instruction information transmission module, matches the patient's physiological information and the patient's physiological basic information according to the information after the instruction is executed, and if they match, transmits the corresponding information to the information recording and integration module for recording;

[0012] If it does not match, the information feedback and intelligent decision-making assistance module will transmit the non-matching to the multi-dimensional instruction information transmission module for instruction adjustment until the information feedback and intelligent decision-making assistance module match.

[0013] Preferably, the basic information of the patient includes gender, age, weight and the part to be examined, and the physiological information of the patient is detected and recorded according to the part to be examined.

[0014] Preferably, the patient's basic physiological information includes respiration, heart rate and body structure.

[0015] Preferably, the physiological information detection module includes a millimeter wave radar and an electrocardiogram module placed at the tail side of the scanning bed to obtain the patient's physiological information.

[0016] Preferably, when the instruction is that the patient should hold his breath, the millimeter-wave radar detects the chest or abdominal wall and records it as the patient's physiological information and transmits it to the information feedback and intelligent decision-making support module. If the patient's physiological information is inconsistent with the information corresponding to the patient's basic physiological information when holding his breath, the inconsistency will be transmitted to the multi-dimensional instruction information transmission module, and the multi-dimensional instruction information transmission module generates adjusted instructions based on the patient's physiological information.

[0017] Preferably, when the information feedback and intelligent decision-making assistance module determines that the degree of inconsistency between the patient's physiological information and the information corresponding to the patient's basic physiological information when holding breath exceeds a preset threshold, the information feedback and intelligent decision-making assistance module will transmit a prompt exceeding the preset threshold to the multi-dimensional instruction information transmission module to prompt the operating physician.

[0018] Preferably, the information feedback and intelligent auxiliary decision-making module predicts and evaluates the generation of artifacts based on the motion amplitude.

[0019] Preferably, the multi-dimensional instruction information transmission module obtains real-time sensory feedback information from the patient and promptly alerts the operating physician of the patient's current physiological sensation.

[0020] The present invention proposes a real-time, multi-dimensional information interaction system for medical scanning. This system enables real-time, multi-dimensional information exchange between patients and operators during the scanning process. It uses simple, clear body movement demonstrations and colorful, flashing text to guide patients throughout the scanning process. This system allows patients with hearing impairments, those with diverse cultural differences, and those who are elderly and frail to complete the entire scan independently. Furthermore, if a patient experiences physical discomfort or a contrast agent allergy during the scan, they can notify the operator via the scanner's display, resolving the issue of patients being unable to express their concerns or expressing them inaccurately. Furthermore, a camera and radar detector within the scanner's display monitor the patient's scan area in real time during the scan. If any movement or incompatibility is detected, the system prompts the patient to remain still. After the scan is complete, the system generates a curve based on the patient's movement during the scan. It also automatically records and saves the interaction information between the operator and patient during the scan, providing examples and reference for subsequent scans. This allows for personalized scanning information solutions for each patient, offering unique advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.

[0028] An embodiment of the present invention provides a real-time multi-dimensional information interaction system for medical scans, comprising:

[0029] Basic Information Detection Module: This module obtains basic patient information, including gender, age, weight, and the area to be examined. Based on the area to be examined, the module detects and records the patient's physiological information, which is then organized and analyzed in conjunction with the patient's basic information. This information, including basic physiological information such as respiration, heart rate, and body structure, serves as the basis for individualized comparisons required for subsequent examinations. Given the significant differences in physiological characteristics between individuals, the module first receives the patient's basic information.

[0030] Multi-dimensional instruction information transmission module: retrieves the patient's basic information and the patient's physiological basic information from the basic information detection module, and generates instruction voice, body demonstration movements and colored flashing eye-catching text according to the patient's basic information and the patient's physiological basic information to issue instructions.

[0031] For example, when the patient is required to hold their breath, a voice prompt sounds, and a corresponding body movement demonstration and text prompting the patient to hold their breath appear on the left side of the scanner's display. When breath holding is complete and breathing is allowed freely, a voice prompt sounds, and a free breathing movement demonstration and text prompting the patient to relax and breathe freely appear on the left side of the scanner's display. When the patient is required to remain still to ensure imaging stability, a voice prompt sounds, and a remaining movement demonstration and text prompting the patient to remain still appear on the left side of the scanner's display. The integrated visual and auditory multi-information interaction facilitates the understanding of instructions during scanning examinations for patients from different cultural backgrounds and the elderly and frail.

[0032] Physiological Information Detection Module: This module, comprised of a millimeter-wave radar and electrocardiographic (ECG) module located at the end of the scanning table, accurately detects the patient's movements and acquires physiological information through electrocardiographic (ECG) induction. During the CT or MR scan, the patient's movements are detected by the Physiological Information Detection Module and compared with previously acquired baseline physiological information.

[0033] If the detected patient physiological information does not match the information obtained after the patient's basic physiological information is executed according to the instructions, it will be transmitted to the information feedback and intelligent decision-making support module for analysis. For example, when the patient is prompted to hold his breath, if the patient does not cooperate or cooperates poorly, the radar wave detects movement of the chest or abdominal wall, and the information will be immediately presented to the operator interface and transmitted to the decision-making support module. When a significant change is detected in the patient's physiological information and the basic information previously recorded, the information will be transmitted to the information feedback and intelligent decision-making support module for evaluation and feedback to the operating physician.

[0034] Information Feedback and Intelligent Decision-Making Module (Comparison with Basic Information, Analysis and Processing of Abnormal Information): After obtaining the patient's physiological information, it is paired and analyzed with the patient's basic physiological information after the instruction is executed. If the instruction is a static state, the physiological information detection module will match the physiological information such as movement and heart rate with the patient's basic physiological information. If the instruction is breath-hold or continuous breathing, the detection information and the corresponding physiological information are matched and analyzed.

[0035] If the matched information doesn't match, it's transmitted to the Multi-Dimensional Instruction Information Transmission Module, generating a notification indicating poor coordination. The Information Feedback and Intelligent Decision-Making Module compares the magnitude of the motion to predict and assess the amount of artifacts. It also indicates the time and plane of motion, allowing the precise location and magnitude of artifacts or image artifacts. This eliminates the need for doctors to visually assess patient coordination and the location of poor images after all images have been calculated and displayed.

[0036] If a patient requires a long examination, movement or poor coordination during the exam may not be easily detected by the doctor. Waiting until the entire examination is complete to assess image quality and determine if it is substandard will waste time and reduce the patient's tolerance. This is more reliable and timely than the operator's subjective decision to wait for the examination to end and then conduct a comparison check later. This significantly reduces the chance of exam failure and improves work efficiency.

[0037] Furthermore, when a patient experiences an allergic reaction to an injected test drug, the operating physician cannot immediately detect physiological changes in the patient because radiological examinations are performed in closed examination rooms. The examination is often stopped and intervention is initiated only after the patient experiences severe discomfort. When using a real-time multi-dimensional information interaction system, patients can manually select alarms and voice alarms using an interactive screen placed on the side of their head. When an allergic reaction occurs, breathing, abnormal body movements, and sudden changes in heart rate are often the first important vital signs to show significant changes compared to basic physiological information. The real-time multi-dimensional information interaction system will immediately issue an alarm after comparing basic information. Alternatively, when a critically ill patient experiences a sudden change in condition and is unable to choose an alarm due to their condition, the multi-dimensional intelligent information feedback system can automatically transmit physiological information changes to the operating physician's screen and issue a buzzer alarm.

[0038] Information Recording and Integration Module: After completing information monitoring and decision-making support, the examination data will be recorded in the patient's examination file for future reference. The operator's evaluation of the scan results and any notes will also be recorded and integrated with the scan parameters to complete the patient's scan information library.

[0039] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a use process of a medical scan real-time multi-dimensional information interaction system as follows:

[0040] After the patient is positioned on the scanning machine, the display screen folded on the scanning machine is unfolded and placed above the patient's head. After the patient is positioned, the information interaction device of the real-time multi-dimensional information interaction system provided by the above embodiment of the present invention is unfolded.

[0041] After the scan begins, the operator can adjust the multi-dimensional information received by the patient during the scanning process of the real-time multi-dimensional information interaction system according to the scanning requirements. When the instruction voice sounds, the left side of the scanning machine display screen in the real-time multi-dimensional information interaction system will display corresponding body demonstration movements and colored flashing eye-catching text to provide multi-dimensional prompts to the patient.

[0042] When the patient needs to hold his breath, the instruction voice sounds, and a breath-holding body movement demonstration and text prompts the patient to hold his breath will appear on the left side of the scanning machine display screen; when the breath holding is completed and he can breathe freely, the instruction voice sounds, and a free breathing movement demonstration and text prompts the patient to relax and breathe freely will appear on the left side of the scanning machine display screen; when the patient needs to remain still to ensure the stability of the imaging, the instruction voice sounds, and a still movement demonstration and text prompts the patient to remain still will appear on the left side of the scanning machine display screen, that is, the real-time multi-dimensional information interaction system guides the patient to complete the cooperative movements and precautions during the scanning.

[0043] On the right side of the scanning machine display screen is the patient operation interface, which has options for patients to operate. If the patient feels uncomfortable or has other demands during the scanning process, they can click on the screen, and a corresponding reminder will appear on the operation screen of the operating room to receive patient information during the scanning process.

[0044] During scanning, the camera in the display screen will capture the image of the patient's scanning part and feed it back in real time on the operating screen in the operation room. At the same time, corresponding monitoring will be carried out. When abnormal shaking of the scanning part of the patient is detected during scanning, a movement demonstration and text prompting the patient to keep still will appear on the display screen of the scanning machine. A prompt will also appear on the operating screen in the operation room to remind the operator of the time and amplitude of the patient's shaking, so as to monitor changes in the scanning part during the patient's scanning process.

[0045] After the scan is completed, the interactive system automatically records and saves the interaction between the operator and the patient during the scanning process, and generates a change curve based on the movement amplitude of the patient's scanned area during the scanning to automatically record and save the interaction process and perform personalized information recording.

[0046] Taking a 62-year-old patient with liver mass undergoing magnetic resonance imaging as an example, a medical scanning real-time multi-dimensional information interaction system provided by an embodiment of the present invention is used. Figure 4 A in the figure indicates that the patient cannot effectively understand the breath-hold voice prompt. The information feedback and intelligent decision-making support module prompts that the image quality at the liver portal level is poor, affecting the diagnosis result. Figure 4 B in the figure indicates that the operator demonstrates the movements during scanning, which the patient can understand and effectively hold his breath, thus significantly improving the image quality.

[0047] Figure 5 A in the figure indicates that the patient cannot cooperate effectively due to poor hearing, and the cardiac magnetic resonance T2WI scan image has large artifacts, which affects the examination results. Figure 5 B in the figure shows the operator demonstrating the movements during the scan. The patient cooperated well, the artifacts disappeared, and the lesions were clearly displayed.

[0048] Physiological information detection module performs breathing detection such as Figure 6 As shown, breathing segments 1, 2, and 4 are stable stages, and breathing segment 3 is an unstable stage.

[0049] Compared with the existing method of unilaterally guiding patients to complete medical imaging scans through voice broadcasts by operators, the advantages of the embodiments of the present invention are as follows:

[0050] 1. The real-time multi-dimensional information interaction system for medical scanning provided by the embodiment of the present invention can realize real-time multi-dimensional information interaction between operators and patients during the scanning process, thereby avoiding the failure to timely detect drug allergies of patients due to communication barriers during the scanning process, and the failure of operators to understand other patients' demands in real time, and effectively avoiding the omission of patients' demands.

[0051] 2. When facing patients with hearing impairments, multi-regional language and cultural differences, and the elderly and frail, who are unable to complete the corresponding instructions during the scanning process according to the voice broadcast, this interactive system can guide patients to complete the required actions during the scanning process through simple and clear action demonstrations and colorful flashing eye-catching text. The operator's action requirements for the scan can be more intuitively known to the patient.

[0052] 3. The real-time multi-dimensional information interaction system for medical scanning provided by the embodiments of the present invention can monitor the patient's scanned area and physiological information in real time during the scanning process. When abnormal shaking of the scanned area is detected, the operator can be reminded accordingly on the operation screen in the operation room. The system can also provide multi-dimensional prompts to the patient. Compared with the current practice of only discovering poor image quality due to patient shaking after the image is generated, this system reduces the need for repeated scans, improves the efficiency of scanning examinations, and reduces the occurrence of poor images and the possibility of patients being exposed to more radiation.

[0053] 4. The embodiment of the present invention provides a medical scanning real-time multi-dimensional information interaction system with its main terminal located at the patient's head. Regardless of whether the examination bed is stationary or scanning, the real-time multi-dimensional information interaction is not affected, and the system has a wide range of applications.

[0054] 5. The real-time multi-dimensional information interaction system for medical scanning provided by an embodiment of the present invention can generate a change curve based on the movement amplitude of the patient's scanned part during the scanning process, record and save the interaction information between the operator and the patient during each scanning process, and provide a sample reference for subsequent re-scanning of the patient, making the scanning process more targeted and personalized. The scanning plan can improve the accuracy and safety of the scan.
