[0002] With the development of computer technology, magnetic resonance imaging (MRI) equipment is also becoming increasingly intelligent.

[0003] In related technologies, operators need to be trained before using magnetic resonance imaging (MRI) equipment to gain a basic understanding of its operation. During the MRI scan, operators consult the user manual to set the equipment parameters to ensure the scan proceeds smoothly.

[0004] However, the parameter setting process of magnetic resonance equipment is quite complex, and it is difficult to improve the quality of magnetic resonance images by relying solely on the operator's existing knowledge.

[0069] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0070] Before providing a detailed introduction to the technical solution of this application, let me first briefly introduce the background technology of this application.

[0071] When operators set the parameters of an MRI machine without proper training, the resulting medical images will inevitably be of poor quality.

[0072] In related technologies, operators need to be trained before using MRI equipment to gain a basic understanding of its operation. Specifically, for novice operators, trainers will spend 2-3 hours training on the safe operation and relevant regulations of the MRI equipment. Then, 1-2 days will be dedicated to introductory training, followed by 3 days of scanning training. Introductory training includes hardware and software training, while scanning training covers positioning specifications and protocol customization. For experienced operators, the training focuses on explaining parameter settings for different scanning difficulties and answering questions encountered during actual operation. For highly skilled operators, the training primarily provides more refined parameter adjustment methods and techniques for complex scanning tasks. For upgrades involving new applications within the MRI equipment, trainers will spend 1 day training on the upgrade content (e.g., trial methods, positioning specifications, and protocol customization), followed by 1 day guiding operators through the trial and answering their questions.

[0073] During a magnetic resonance imaging (MRI) scan, operators consult the user manual to set the parameters of the MRI equipment to ensure the scan proceeds smoothly.

[0074] However, due to the sheer volume of training content for MRI equipment (e.g., the 3T model), it's impossible to cover everything within a limited timeframe. This leads to various problems encountered by operators during actual operation of the equipment. Face-to-face training requires specific times and locations, meaning trainers and operators need to be available at the same time and place, making time coordination difficult. The quality of the training process can be affected by the trainer's experience, skills, and teaching methods. In some cases, trainers cannot meet the needs of all operators, resulting in unsatisfactory training outcomes. Furthermore, each training session is designed for multiple operators, making it impossible to personalize training based on each operator's individual needs. This may lead to the training knowledge not matching actual work requirements. During face-to-face training, the learning progress of different operators may vary due to individual abilities, prior knowledge, and learning habits. Some operators may struggle to keep up, while others may feel the training is too slow. Most importantly, face-to-face training is typically conducted in a short period, and operators quickly forget the training content afterward.

[0075] After training, trainers need to provide additional consultations to operators during their non-training hours, which adds to the workload for both trainers and operators. Furthermore, operators cannot receive timely professional guidance for problems encountered during actual operation. Additionally, differences in skill levels among different operators can lead to inconsistencies in the quality of medical image scans.

[0076] Assuming that MRI equipment is set to a fully automated scanning process, operators' skills will gradually deteriorate over time due to prolonged inactivity. Furthermore, the lack of real-time monitoring and anomaly alerts during automated scanning cannot guarantee the safety and accuracy of the process.

[0077] To address the aforementioned problems, this application provides a magnetic resonance imaging (MRI) scanning method, an MRI equipment control method, and a medical device. By utilizing the scanning specification database within the MRI equipment's accompanying scanning system, the scanning process can be accurately guided, thereby improving the quality of medical images. Simultaneously, it avoids the need for interaction between trainers and operators. During the scanning process, interaction between the MRI equipment and the operator allows for practical operational guidance, making it easier for operators to grasp the training content. Of course, the technical solutions provided in this application are not limited to solving only the above-mentioned problems and also possess other technical effects, which can be specifically described in the following embodiments. The technical solutions of this application will now be described in detail.

[0078] The scanning method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown includes a magnetic resonance imaging (MRI) device 10, which includes a companion scanning system 101. The MRI device 10 is used to scan the object and obtain scanned images. The companion scanning system 101 is used to output scanning prompt messages to the operator in a timely manner before and during the scanning process.

[0079] In one exemplary embodiment, such as Figure 2 As shown, a magnetic resonance scanning method is provided, which can be applied to... Figure 1 Taking a magnetic resonance imaging (MRI) device as an example, the explanation includes the following steps 101 to 103. Wherein:

[0080] S101, Obtain the scanning requirements information of the object to be scanned and the current step of the magnetic resonance scan.

[0081] The scanning requirements information indicates the needs for scanning the object. These requirements can include the MRI equipment, the scanning area, and the type of scan. The scanning area can be the head, chest, or abdomen, and the scan type can be a plain head MRI, brain functional imaging, cerebral arterial imaging, cerebral venous imaging, or brain perfusion imaging, etc.

[0082] In this embodiment, the MRI machine can receive an electronic examination report of the scanned object sent by the examination report system. This electronic examination report is provided by the doctor based on the scanned object's physiological characteristics and past medical history. The report is then parsed to determine the scanned object's scanning requirements. Alternatively, the operator can select content from a paper examination report provided by the doctor on the MRI machine's interface to generate the scanned object's scanning requirements. Furthermore, the MRI machine can also analyze the scanned object's physiological characteristics and past medical history to determine its scanning requirements. This embodiment does not limit the method of obtaining the scanned object's scanning requirements.

[0083] The magnetic resonance imaging (MRI) scan process includes pre-scan preparation and the actual scan. Therefore, the current step in the MRI scan described above can be either the current scan preparation step or the current scan step. For example, the current scan preparation step could include steps such as pre-scan protocol selection, protocol parameter adjustment, positioning, or field of view selection. The current scan step refers to some steps in the actual scan process.

[0084] Computer equipment can determine the current step of an MRI scan by monitoring video information collected from the operating space where the MRI machine is located. Alternatively, the computer can also determine the current step of the MRI scan in response to prompts entered by the operator. For example, the operator can input the current step of the MRI scan via voice or text.

[0085] S102, based on the scanning specification database of the magnetic resonance equipment, the current step, and the scanning requirement information, determine the operation guidance information that matches the current step; the scanning specification database stores the scanning operation knowledge of the magnetic resonance equipment under various scanning types; the operation guidance information includes operation information and the corresponding operation principle.

[0086] The scanning specifications database includes operational knowledge for MRI equipment across various scanning types. Specifically, this knowledge includes positioning guidelines, key points for positioning, methods for verifying positioning accuracy, key points for images with different contrast ratios, scanning procedure guidance, and process descriptions. Positioning guidelines provide standard positioning instructions for different body parts, along with image-assisted explanations, including visual examples of ideal positioning and annotations of the current standard positioning items' orientations in macroscopic cross-sectional views. Key points for positioning address crucial positioning points and common pitfalls for different scanned body parts, including evaluation criteria and techniques for positioning accuracy. Methods for verifying positioning accuracy describe how to confirm the accuracy of the scanned object and MRI equipment's positioning, combining technical checks and visual assessments. Key points for images with different contrast ratios detail the diagnostic characteristics and uses of images with different contrasts and resolutions, providing typical cases and images illustrating diagnostic priorities in specific situations. Simultaneously, the database displays the macroscopic cross-sectional view of the current scanned image on the human body during the scanning process, facilitating a visual understanding of the current scanned position. The scanning procedure guide and process descriptions cover all stages of the scanning process, including the configuration of the MRI equipment, selection of scanning parameters, image acquisition and image post-processing, providing standardized guidelines and best practices for the operation process.

[0087] Scan operation knowledge for any scan type includes operation information and the corresponding operation principle. Operation information refers to the relevant information that the user needs to perform in the current step. The corresponding operation principle refers to the reason why the user performs the relevant operation. For example, the operation information matching the current step is to adjust the patient's position to a lateral decubitus position. The corresponding operation principle could be to understand the size and shape of the patient's region of interest on the side by using the lateral decubitus position.

[0088] In this embodiment, after obtaining the scanning requirements information and current step of the scanned object, the magnetic resonance imaging (MRI) device can retrieve scanning operation knowledge matching the current step from the scanning specification database using data retrieval. Based on this scanning operation knowledge, it generates operation guidance information matching the scanning requirements information. Alternatively, the MRI device can also obtain the similarity between multiple scanning operation knowledge pieces and the scanning requirements information in the scanning specification database, and select the scanning operation knowledge with the highest similarity as candidate scanning operation knowledge. From the candidate scanning operation knowledge, it selects the scanning operation knowledge matching the current step, and based on this scanning operation knowledge, it generates operation guidance information matching the current step.

[0089] S103, Generate a scanning prompt message based on the operation guidance information.

[0090] In this embodiment, the scan prompt messages can be provided in a format easily understood by the operator, such as image, video, audio, or text. The scan prompt messages are used to guide the operator to adjust the parameters of the MRI equipment and the pose of the scanned object accordingly. These prompt messages include those during the scan and those after the scan. For example, pre-scan prompts may include coil and / or patient positioning information, protocol parameter adjustment information, etc.; during the scan, prompts may include process reminders, instructions on when to pause the scan for medication administration, or monitoring information, such as whether the patient's positioning needs readjustment. Post-scan prompts include image optimization information, etc.

[0091] In this embodiment, the magnetic resonance imaging (MRI) device can use operation guidance information as a scanning prompt message, or select a portion of the information from the operation guidance information as a scanning prompt message, and display the resulting scanning prompt message to the operator or the object being scanned. For example, if the scanning prompt message is parameter information of the MRI device, the prompt message is displayed to the operator. If the scanning prompt message is pose information of the object being scanned, the prompt message is displayed to the object being scanned.

[0092] In the aforementioned magnetic resonance imaging (MRI) scanning method, the scanning requirements information of the scanned object and the current step of the MRI scan are obtained. Based on the MRI equipment's scanning specification database, the current step, and the scanning requirements information, operation guidance information matching the current step is determined. The scanning specification database stores scanning operation knowledge of the MRI equipment under various scanning types. The operation guidance information includes operation information and the corresponding operation principle. Scan prompt messages are generated based on the operation guidance information. This method provides an MRI equipment with a scanning specification database storing scanning operation knowledge of the MRI equipment under various scanning types. Thus, whether in the pre-scan preparation stage or during the scan, the operation guidance information matching the current step can be accurately retrieved from this scanning specification database based on the scanned object's scanning requirements information and the current step. This operation guidance information includes operation information and the corresponding operation principle. Therefore, the real-time scan prompt messages generated based on this operation guidance information allow operators to make timely and accurate adjustments and learn the adjustment principles. By training operators during actual scanning processes, the accuracy of the scanning process is improved, thereby enhancing the quality of medical images.

[0093] In one embodiment, such as Figure 3 As shown, the specific content of the operation guidance information that matches the current step based on the scanning specification database of the magnetic resonance imaging equipment and the scanning requirement information is described above. This specific content includes:

[0094] S201, confirm that the user has enabled the scan prompt function.

[0095] In this embodiment, the scan prompt function can be activated by the user pressing a corresponding button, or by the user pressing a key on the display screen, or by the user clicking with the mouse. Regardless of the method, once the computer device receives the scan prompt function, it can determine that the user has activated the scan prompt function.

[0096] S202, Based on the scanning requirements information and the current step, match the operation guidance information corresponding to the current step from the scanning specification database.

[0097] In this embodiment, the current step can be either the current scan preparation step or the current scan step. Regardless of whether it's the current scan preparation step or the current scan step, the computer device can search for scan knowledge matching the scan requirement information from the scan specification database based on the scan requirement information. Then, it can filter the scan knowledge matching the scan requirement information to select the operation guidance information corresponding to the current step.

[0098] In the aforementioned magnetic resonance imaging (MRI) scanning method, it is determined that the user has enabled the scan prompt function. Based on the scan requirement information and the current scan step, the method matches the operation guidance information corresponding to the current step from the scan specification database. By using the scan requirement information and the current scan step, this method can gradually narrow down the search range of the scan specification database, accurately find the operation guidance information corresponding to the current step from the scan specification database, thereby achieving real-time guidance during the MRI scanning process.

[0099] Assuming the operation guidance information includes pre-scan guidance information and scanning process guidance information, then, for the preparation process before a magnetic resonance imaging (MRI) scan, the operation guidance information includes pre-scan guidance information, and the current step includes the current scan preparation step. In one embodiment, such as... Figure 4 As shown, the specific content of matching the operation guidance information corresponding to the current step from the scanning specification database based on the scanning requirement information and the current scanning step is described below. This specific content includes the following steps:

[0100] S301, based on scanning requirement information, obtain the target scanning area and target scanning type of the object being scanned.

[0101] In this embodiment of the application, the scanning requirement information of the scanned object carries the scanning location and scanning type. The magnetic resonance device can analyze the scanning requirement information of the scanned object to obtain the target scanning location and target scanning type of the scanned object.

[0102] S302, based on the target scanning area, target scanning type, and current scanning preparation steps, search the scanning specification database for pre-scan guidance information that matches the current scanning preparation steps.

[0103] In this embodiment, the scanning specification database stores pre-scan guidance information and scanning process guidance information for multiple scanning sites. For the pre-scan guidance information for multiple scanning sites, the scanning preparation knowledge for each scanning site includes scanning preparation knowledge for various scanning types. Based on this, the magnetic resonance imaging (MRI) device can obtain the similarity between the target scanning site and multiple scanning sites in the scanning specification database, and use the scanning preparation knowledge corresponding to the scanning site with the highest similarity as the scanning preparation knowledge corresponding to the target scanning site.

[0104] Furthermore, since a scan site includes multiple scan types, the magnetic resonance imaging device can calculate the similarity between each scan type under the target scan site and the target scan type, and use the scan preparation knowledge of the scan type with the highest similarity as the scan preparation knowledge corresponding to the target scan type.

[0105] In addition, the MRI equipment can select the guidance information corresponding to the current scan preparation step from the scan operation knowledge that matches the target scan type, based on the current scan preparation step.

[0106] For example, the pre-scan guidance information corresponding to the current scan preparation step follows a workflow, including patient information and examination requirement verification guidance, scan protocol guidance, patient positioning and coil setup guidance, or pre-examination status guidance, etc., to guide the user from information verification to examination status according to the above workflow. Specifically, the patient information and examination requirement verification guidance refers to the MRI equipment automatically analyzing the patient's medical history and examination records to suggest priority scan protocols for suspected diseases (e.g., cerebral infarction suggests magnetic resonance angiography (MRA), liver suggests dynamic contrast-enhanced scanning, etc.). It also provides explanations of the principles behind the priority scan protocols (e.g., the reasons for choosing contrast agent A, the reasons for choosing a specific scan sequence, etc.). The scan protocol guidance information recommends the best scan protocol based on the target scan site (e.g., head, abdomen, etc.), the patient's condition (e.g., breath-holding ability, resting cooperation level), and clinical needs, providing visual justifications and medical support materials. For example, for patients with difficulty holding their breath, it automatically recommends a free breathing sequence and explains its applicability. Furthermore, after the operator selects a scanning protocol, the MRI machine determines whether the protocol meets the current requirements and provides optimization suggestions. Patient positioning and coil setup guidance information provides standard positioning steps, accompanied by 3D animations or images, to ensure accurate positioning of the scanned object. For example, when the region of interest is the head, it guides the scanned object's neck elevation angle and body center alignment. It also monitors the coil connection status in real time, prompting for correct placement and adjustment methods to avoid poor signal quality. Pre-examination status guidance information includes equipment status guidance information and scanned object cooperation guidance information. Equipment status guidance information automatically detects the MRI machine's status (e.g., magnet cooling, gradient coil performance) and alerts users to potential issues affecting the scan. Scanned object cooperation guidance information involves the MRI machine confirming, through voice or screen interaction, that the scanned object understands breath-holding commands or other cooperation requirements.

[0107] In the aforementioned magnetic resonance imaging (MRI) scanning method, the target scanning area and target scanning type are obtained based on scanning requirement information. Then, according to the target scanning area, target scanning type, and current scanning preparation step, pre-scan guidance information matching the current scanning preparation step is searched from the scanning specification database. This method can analyze scanning requirement information to accurately obtain the target scanning area and target scanning type. Therefore, it can progressively filter through the scanning specification database based on the target scanning area, target scanning type, and current scanning step, specifically searching for pre-scan guidance information matching the current scanning step. This allows for accurate real-time guidance during the pre-scan preparation stage based on this pre-scan guidance information.

[0108] Regarding the magnetic resonance scanning process, in one embodiment, such as Figure 5 As shown, the specific content of matching the operation guidance information corresponding to the current step from the scanning specification database based on the scanning requirement information and the current scanning step is described below. This specific content includes:

[0109] S401, Obtain monitoring information of the scanned object and scanning status information of the magnetic resonance equipment under the current scanning step.

[0110] Monitoring information refers to physiological indicators of the subject during the scanning process using an MRI scanner. For example, monitoring information could include the subject's heart rate and respiratory rate. Scanning status information refers to the actual parameters of the MRI scanner during the scanning process; for example, actual parameters could include radiofrequency energy and temperature.

[0111] In this embodiment, during the scanning process using a magnetic resonance imaging (MRI) device, the MRI device can simultaneously acquire images of the scanned object using its own imaging equipment and analyze the monitoring information of the scanned object based on these images. Simultaneously, the current operating parameters of the MRI device during the scanning process are stored in a memory, which can be used as the scanning status information of the MRI device.

[0112] S402, based on monitoring information and scanning status information, retrieve guidance information for the scanning process that matches the current scanning step from the scanning specification database.

[0113] In this embodiment, after obtaining the monitoring information of the scanned object and the scanning status information of the magnetic resonance imaging (MRI) device under the current scanning step, the MRI device can search for scanning knowledge that matches the monitoring information from the scanning specification database to obtain candidate scanning knowledge. Then, it selects the scanning knowledge that matches the scanning status information from the candidate scanning knowledge and uses this scanning knowledge as guidance information for the scanning process matching the current scanning step.

[0114] For example, the guidance information during the scanning process corresponding to the current scanning step follows a workflow, including real-time parameter monitoring and optimization, key operation reminders, macroscopic cross-sectional views and positioning feedback, abnormal state detection and response, and scanning progress and image quality analysis, to guide the user to operate according to the scanning process. Real-time parameter monitoring and optimization includes scan quality prompts and motion parameter adjustment suggestions. Scan quality prompts monitor parameters during the MRI scan, analyze the quality of the monitored data (e.g., signal-to-noise ratio, motion artifacts), and remind users of adjustment strategies. For example, when patient movement is detected, prompts may suggest repositioning or selecting a motion correction sequence. Motion parameter adjustment suggestions provide timely suggestions for adjusting motion parameters based on the scan situation (e.g., optimizing the scanning field of view, slice thickness, etc.). Key operation reminders include injection dosage and time management and breath-hold status monitoring. Injection dosage and time management, when contrast agents are used, prompts the optimal injection timing and scan delay time to ensure imaging results. For example, in contrast-enhanced scanning, prompts may indicate a 30-second delay after injection before starting the scan, while also indicating the optimal acquisition window. Breath-hold status monitoring monitors the patient's breath-hold status in real time, prompting the user to stop the scan or restart breath-hold training in a timely manner. Macroscopic section view and positioning feedback include section position visualization and positioning item verification. Section position visualization displays the 3D macroscopic position of the current slice within the patient's body during scanning, helping users intuitively understand the current imaging area. Positioning item verification performs real-time verification of important positioning items (such as the AC-PC line in head scans) and provides error correction suggestions. Abnormal state detection and response include patient status monitoring and device anomaly feedback. Patient status monitoring integrates physiological indicators such as heart rate and respiratory rate to provide real-time alerts for abnormal conditions (e.g., patient anxiety leading to unstable breathing). Device anomaly feedback reports in real-time when device anomalies are detected (such as radiofrequency power leakage or overheating) and suggests interrupting or adjusting the scanning protocol. Scan progress and image quality analysis include real-time scan progress display and quick image preview and evaluation. Real-time scan progress display shows the scan progress through an intuitive interface, including remaining time and the current step. Quick image preview and evaluation automatically generates a preliminary image quality analysis report after each acquisition step, indicating whether re-scanning is necessary.

[0115] In the aforementioned magnetic resonance imaging (MRI) scanning method, monitoring information of the scanned object and scanning status information of the MRI equipment are acquired at the current scanning step. Based on the monitoring information and scanning status information, guidance information for the scanning process matching the current scanning step is retrieved from the scanning specification database. During MRI scanning, this method, through the monitoring information of the scanned object and the scanning status information of the MRI equipment at the current scanning step, can selectively filter from the scanning specification database from two dimensions to accurately determine the guidance information matching the monitoring information and scanning status information, thereby accurately obtaining the guidance information for the scanning process matching the current scanning step.

[0116] Assuming the guidance information for the scanning process includes parameter adjustment information and state adjustment information, in one embodiment, such as Figure 6 As shown, the specific content of the guidance information for finding the scanning process that matches the current scanning step from the scanning specification database includes:

[0117] S501, retrieve the target parameters and target status that match the current scanning step from the scanning specification database.

[0118] In this embodiment, each scanning stage corresponds to the target parameters of the magnetic resonance imaging (MRI) device and the target state of the scanned object. The MRI device can search for the parameters and states corresponding to the identification information of the scanning stage from the scanning specification database, and use the parameters as the target parameters matching the current scanning step, and use the states as the target states matching the scanning stage.

[0119] S502, based on the current scanning parameters and target parameters, generates parameter adjustment information; and based on the current state and target state, generates state adjustment information.

[0120] Among them, the current scanning parameters can be the actual parameters of the magnetic resonance device during the scanning process of the scanned object, and the current state refers to the actual state of the scanned object during the scanning process.

[0121] In this embodiment, the magnetic resonance imaging (MRI) device can calculate the parameter difference between the current scanning parameters and the target parameters, and use this parameter difference as parameter adjustment information. It can also acquire the state difference between the current state and the target state of the scanned object, and use this state difference as state adjustment information. For example, the parameter adjustment information may be scanning field of view adjustment information or slice thickness adjustment information. The state adjustment information may be pose adjustment information, respiration adjustment information, etc.

[0122] It should be noted that during each scanning phase, the MRI machine can analyze the quality of the scanned object's data in real time (e.g., signal-to-noise ratio, motion artifacts, etc.) and provide adjustment suggestions. It can also provide adjustment recommendations based on the scanned object's data. For example, when movement of the scanned object is detected, the adjustment information could be repositioning or selecting a motion correction sequence.

[0123] In addition, MRI equipment can display the 3D macroscopic position of the current slice within the patient's body during scanning, helping operators to intuitively understand the current imaging area. It also performs real-time verification of important positioning items (such as the AC-PC lines in head scans) and provides error correction suggestions.

[0124] During the scan, the MRI machine can also visually display the scan progress on the screen, including the remaining scan time and the current scan step.

[0125] In the aforementioned magnetic resonance imaging (MRI) scanning method, target parameters and target states matching the current scanning step are obtained from a scanning specification database; parameter adjustment information is generated based on the current scanning parameters and target parameters; and state adjustment information is generated based on the current state and target state. This method accurately determines the scanning object and the target to be adjusted for the MRI equipment by searching the scanning specification database for the target parameters and target states corresponding to the current scanning step. It then accurately generates parameter adjustment information based on the current scanning parameters and target parameters, and accurately generates state adjustment information based on the current state and target state.

[0126] If the guidance information for the scanning process also includes abnormal guidance information, then the following example will describe the specific content of the guidance information for the scanning process that matches the current scanning step from the scanning specification database. Figure 7 As shown, the specific content includes:

[0127] S601, detect whether there are any abnormalities in the monitoring information of the scanned object and / or the scanning status information of the magnetic resonance equipment.

[0128] The monitoring information can include integrated physiological indicators of the scanned object, such as heart rate and respiratory rate. The scanning status information can include parameters such as device radio frequency leakage and temperature.

[0129] In this embodiment, the magnetic resonance imaging (MRI) device can detect the integrity of the scanned data during the scanning phase. If the scanned data is complete, it is considered to be free of abnormalities; if the scanned data is incomplete, it is considered to be abnormal. Alternatively, the MRI device can compare the scanned data with ideal data to determine if the difference between the two is too large. If the difference is too large, it is determined that the scanned data is abnormal; if the difference is small, it is determined that the scanned data is not abnormal.

[0130] In addition, the computer equipment can compare the scanning status information of the magnetic resonance imaging (MRI) device in the current scanning step with preset scanning status information to determine the information error between the two. If the information error is greater than or equal to the preset error, it is determined that the scanning status information of the MRI scan is abnormal; if the information error is less than the preset error, it is determined that the scanning status information of the MRI scan is not abnormal.

[0131] S602, if an anomaly is found, generate an anomaly guidance message for the scanning process.

[0132] In this embodiment, when an anomaly is detected in either the monitoring information of the scanned object or the scanning status information of the MRI machine, the cause of the anomaly is analyzed based on the knowledge stored in the scanning specification database. Corresponding emergency measures are then obtained and used as guidance information for the scanning process. The cause of the anomaly can be either related to the scanned object or the MRI machine. For example, the cause of the anomaly could be anxiety leading to unstable breathing, while the cause of the MRI machine could be radio frequency leakage or excessive temperature.

[0133] If the cause of the abnormality is related to the MRI equipment, the guidance information could be to stop the scan or adjust the MRI scan protocol. If the cause of the abnormality is related to the patient being scanned, the guidance information could be to instruct the patient to adjust their breathing.

[0134] In the aforementioned magnetic resonance imaging (MRI) scanning method, the system detects whether there are any abnormalities in the monitoring information of the scanned object and / or the scanning status information of the MRI equipment. If an abnormality is found, abnormal guidance information for the scanning process is generated. This method, by performing real-time analysis of the monitoring information of the scanned object and / or the scanning status information of the MRI equipment, can promptly detect abnormal situations during the scanning process, thereby enabling timely acquisition of the abnormal guidance information generated by the abnormal situation to ensure the safety of the scanning process.

[0135] After the scanning process is completed, the magnetic resonance imaging (MRI) device can also reconstruct the scan data using image reconstruction algorithms to obtain an MRI scan image. Furthermore, the quality of this MRI scan image can be assessed, and operational guidance information can be determined based on the assessment results. In one embodiment, such as... Figure 8 As shown, the method also includes:

[0136] S701 performs a quality assessment on the magnetic resonance imaging image obtained after the scan is completed, and obtains the quality assessment result.

[0137] In this embodiment of the application, the scanning specification database may store image quality evaluation criteria. The magnetic resonance device can use the image quality evaluation criteria in the scanning specification database to evaluate the quality of the magnetic resonance scan image obtained after scanning, obtain a quality score for the magnetic resonance scan image, and use the scan image quality score as the quality evaluation result.

[0138] S702, if the quality assessment results do not meet the preset conditions, determine the operation guidance information to match the next magnetic resonance scan.

[0139] In this embodiment, the magnetic resonance imaging (MRI) device can compare the quality score of the MRI scan image with a preset score threshold. If the scan image quality score is greater than or equal to the preset score threshold, it indicates that the quality assessment result meets the preset conditions. If the scan image quality score is less than the preset score threshold, it indicates that the quality assessment result does not meet the preset conditions.

[0140] If the preset conditions are not met, it is necessary to determine whether a second MRI scan is required, and what guidance information is needed during the second MRI scan.

[0141] In the aforementioned magnetic resonance imaging (MRI) scanning method, the quality of the MRI scan image obtained after the scan is completed is evaluated to obtain a quality evaluation result. If the quality evaluation result does not meet preset conditions, operation guidance information matching the next MRI scan is determined. This method, by evaluating the quality of the MRI scan image and providing operation guidance information for the next MRI scan process when the quality evaluation result does not meet preset conditions, accurately guides the next MRI scan process, thereby improving the quality of the MRI scan image obtained in the next MRI scan.

[0142] Magnetic resonance imaging (MRI) equipment can also provide reminders for critical operational procedures. For example, when contrast agents are used, the system prompts for the optimal injection timing and scan delay time to ensure imaging quality. For instance, during contrast-enhanced scans, it prompts a 30-second delay after injection before starting the scan, while also indicating the optimal acquisition window. Furthermore, it monitors the breath-holding state of the scanned subject in real time during critical operations, prompting the technician to stop the scan or restart breath-holding training. Based on this, the following example will illustrate the specific content of the scan prompt messages generated based on the operation guidance information. Figure 9 As shown, the specific content includes:

[0143] S801, based on the identity information of the scanned object, determine whether the current scanning step of the magnetic resonance scan is a step to be prompted.

[0144] The identity information can be unique, identifying information such as the scanned individual's ID number, name, and fingerprints. The pending steps are the crucial preparatory steps before the MRI scan and the key scanning steps during the MRI scan process.

[0145] In this embodiment, the computer device can determine the identity information of the scanned object based on the examination order issued by the doctor. Then, based on the identity information of the scanned object, it determines whether the current scanning step is a critical step. If it is a critical step, the current scanning step of the MRI scan is determined to be a step awaiting prompt; if it is not a critical step, the current scanning step of the MRI scan is determined not to be a step awaiting prompt.

[0146] S802, if the current scanning step is a step to be prompted, then generate a scanning prompt message that matches the step to be prompted based on the operation guidance information.

[0147] In this embodiment, when it is determined that the current scanning step is a step to be prompted, the computer device can use the operation guidance information corresponding to the current scanning step as the scanning prompt information. Alternatively, the computer device can extract key information from the operation guidance information corresponding to the current scanning step and use this key information as a scanning prompt message that matches the step to be prompted.

[0148] In the aforementioned magnetic resonance imaging (MRI) scanning method, the system determines whether the current scanning step is a step requiring prompting based on the identity information of the scanned object. If the current scanning step is a step requiring prompting, a scanning prompt message matching the step is generated based on the operation guidance information. This method uses the identity information of the scanned object to determine whether the current scanning step requires prompting, thereby accurately determining the scanning prompt message matching the current scanning step based on the determination result.

[0149] As a specific embodiment of this application, the magnetic resonance scanning process will now be described in detail. In one embodiment, such as Figure 10 As shown, the magnetic resonance scanning method includes:

[0150] S901, Obtain the scanning requirements information of the scanned object and the current step of the magnetic resonance scan;

[0151] S902, confirm that the user has enabled the scan prompt function;

[0152] S903, based on scanning requirement information, obtains the target scanning part and target scanning type of the scanning object;

[0153] S904, based on the target scanning location, target scanning type, and current scanning preparation steps, search the scanning specification database for pre-scan guidance information that matches the current scanning preparation steps;

[0154] S905, Obtain monitoring information of the scanned object and scanning status information of the magnetic resonance equipment under the current scanning step;

[0155] S906, based on monitoring information and scanning status information, retrieves guidance information for the scanning process that matches the current scanning step from the scanning specification database;

[0156] S907, perform quality assessment on the magnetic resonance scan image obtained after the scan is completed, and obtain the quality assessment result;

[0157] S908, if the quality assessment results do not meet the preset conditions, determine the operation guidance information to match the next magnetic resonance scan;

[0158] S909, Based on the identity information of the scanned object, determine whether the current scanning step of the magnetic resonance scan is a step to be prompted;

[0159] S910, if the current scanning step is a step to be prompted, then generate a scanning prompt message that matches the step to be prompted based on the operation guidance information;

[0160] Figure 11The flowchart illustrates the scanning method, which includes: S1001: Obtaining the patient's (i.e., the scanned object's) examination data source; S1002: Based on the patient's examination data source, determining whether the scanned object is in a critical stage of the examination (i.e., the step to be prompted). If yes, proceed to S1004; if no, proceed to S1005; S1003: Obtaining the system's (i.e., the MRI equipment's) configuration data source; S1004: Based on the system's configuration data source, determining whether the system is performing automatic scanning. If yes, proceed to S1006; if no, proceed to S1005; S1005: Not prompting key information and precautions for the current stage; S1006: Determining whether accompanying scanning is configured. If yes, proceed to S1007; if no, proceed to S1005; S1007: Prompting key information and precautions for the current stage.

[0161] This method provides a companion scanning system to an MRI scanner. During each scanning step, the MRI provides real-time explanations and feedback to the operator, outlining the purpose and principles of the current step. The companion scanning system is designed with educational functions in mind, providing relevant medical knowledge, scanning technology theory, and case studies during the scanning process. For example, the selection of a specific scanning location can be explained, along with its impact on image quality. Simultaneously, real-time feedback and explanation encourage operator participation in the decision-making process, such as allowing manual adjustments to scanning parameters at key points. This design not only improves scanning transparency but also helps maintain and enhance operator professional skills. Furthermore, it can propose optimal scanning strategies based on the specific circumstances of the scanned object and historical data, while explaining the underlying logic and data basis.

[0162] In one embodiment, a magnetic resonance device control method is also provided, such as... Figure 12 As shown, the method includes:

[0163] S1101, Receive automatic scanning command, obtain scanning requirement information of the scanned object and the current step of magnetic resonance scanning;

[0164] S1102, Based on the scanning requirement information, determine whether the current step is a step to be prompted.

[0165] S1103, If it is a step to be prompted, after confirming that the scan prompt function is enabled, the operation guidance information matching the current step is determined according to the scan specification database of the magnetic resonance equipment, the current step, and the scan requirement information; the scan specification database stores the scan operation knowledge of the magnetic resonance equipment under various scan types; the operation guidance information includes operation information and the corresponding operation principle;

[0166] S1104, Generate a scan prompt message based on the operation guidance information and the current step;

[0167] S1105, receives input commands from the user based on feedback messages;

[0168] S1106 controls the operation of the magnetic resonance equipment according to the input command.

[0169] In this embodiment, the automatic scanning command can be a scan command triggered by the user on the MRI machine, or an automatic scanning command sent by the user to the MRI machine through a terminal device. After receiving the automatic scanning command, the computer device can analyze it to determine the scanning requirements of the object being scanned and the current step. It then determines whether the current step is a step requiring prompting, i.e., whether the current step is a critical step. If the current step is determined to be a critical step, after enabling the scan prompt function, it searches the scan specification database for operation guidance information matching the current step, and generates a scan prompt message based on the operation guidance information and the current step. The scan prompt message corresponding to the current step is then displayed to the user on the MRI machine's display screen.

[0170] Based on this, users can determine whether the parameters of the MRI machine need adjustment based on the scan prompts. If adjustment is required, the MRI machine will operate according to the input command fed back from the prompts. In other words, users can participate in the parameter adjustment process during the MRI scan.

[0171] In the aforementioned magnetic resonance imaging (MRI) scanning method, an automatic scanning command is received, and the scanning requirements information of the scanned object and the current step of the MRI scan are obtained. Based on the scanning requirements information, it is determined whether the current step is a step awaiting prompts. If it is a step awaiting prompts, after confirming that the scanning prompt function is enabled, operation guidance information matching the current step is determined based on the MRI equipment's scanning specification database, the current step, and the scanning requirements information. The scanning specification database stores scanning operation knowledge of the MRI equipment under various scanning types. The operation guidance information includes operation information and the corresponding operation principle. A scanning prompt message is generated based on the operation guidance information and the current step. Input commands from the user based on the prompt message are received. The MRI equipment is controlled to operate according to the input commands. This method, upon receiving an automatic scanning command, can obtain the scanning requirements information of the scanned object and the current step of the MRI scan. Furthermore, the MRI equipment provides a scanning specification database storing scanning operation knowledge of the MRI equipment under various scanning types. Thus, whether in the pre-scan preparation stage or during the scan, the operation guidance information matching the current step can be accurately retrieved from the scanning specification database based on the scanning requirements information of the scanned object and the current step. This operation guidance information includes operation information and the corresponding operation principle. Therefore, based on the real-time scanning prompts generated by this operation guidance information, operators can make timely and accurate adjustments and learn the principles of these adjustments. By training operators during actual scanning processes, the accuracy of the scanning process is improved, thereby enhancing the quality of medical images.

[0172] In one embodiment, during the parameter adjustment process of an MRI scan, the system can save and record the user's parameter preferences, questions raised during interaction, and the style of the generated MRI images in the scan specification database. The system can also record the historical scan requirements and data of the scanned object. When the user logs into the system again or the scanned object undergoes a second scan, the system will automatically match the user's parameter setting habits based on their Identity Document (ID), identify the scanned object, retrieve historical scan data, and propose the optimal scan strategy, thereby providing personalized automatic scanning and message prompts.
