Description

Technical Field

[0001] This application relates to the field of medical imaging technology, specifically to a scanning control method for a medical imaging system, a scanning control device for a medical imaging system, and a medical imaging system. Background Technology

[0002] In the field of modern medicine, medical imaging equipment is undoubtedly the doctor's X-ray vision. It can penetrate human tissues and organs, providing crucial image information for disease diagnosis. The emergence and development of these devices have greatly improved the accuracy and efficiency of medical diagnosis, becoming indispensable tools in modern medical diagnosis. To obtain accurate scan results for patients, hospitals typically have specialized radiology technicians operate the medical equipment; the technician's proficiency and experience largely determine the scan results. Hospitals receive a large number of patients daily, posing a significant challenge to radiology departments: First, medical scanning is a complex process, with a lengthy and time-consuming workflow. In traditional medical scanning, technicians spend considerable time on positioning and setup, a cumbersome and energy-consuming process. Second, operators of varying skill levels and experience may produce inaccurate scan data, sometimes requiring repeated scans, leading to inefficiency. Medical scanning requires a high degree of professional skill and precise operation; even minor deviations can affect the scan results.

[0003] In addition to the factors mentioned above, the scanning protocols corresponding to clinical cases are diverse. Traditional medical imaging equipment's professional software or operating systems are almost entirely pre-set by manufacturers according to standard procedures, leaving users with virtually no room for independent adjustment: from the overall interface architecture to the layout of every minute operation button; from the default window names to the shortcut key settings for various functions. Operators face a large number of patients with different conditions every day, and the key to accurate scanning lies in quickly selecting the optimal scanning protocol suitable for the patient from a complex array of protocol packages. However, existing operating interfaces require operators to spend a significant amount of time painstakingly searching for the target protocol package within a monotonous system interface, greatly reducing overall work efficiency. On the other hand, due to the fixed and cumbersome operating procedures, operators under high-intensity work pressure are prone to selecting the wrong protocol due to fatigue or lack of concentration, not only wasting medical resources but also potentially delaying patient diagnosis, resulting in a high rate of human error. With the increasing frequency of multitasking demands, the existing window management model is becoming increasingly apparent: the window names in the operating interface are uniform and lack distinctiveness, making them difficult to quickly identify; the window arrangement order is fixed and cannot be adjusted according to usage frequency; and the shortcut key settings are few and fixed, not conforming to the actual usage habits of operators.

[0004] In summary, the current user interface of medical imaging equipment suffers from limitations in efficiency and user experience due to the developer's pre-defined settings. It lacks actual user autonomy and fails to meet the personalized needs of different operators.

[0005] Therefore, there is an urgent need for a medical imaging system that can support personalized settings in order to improve the operational efficiency and user experience of medical imaging systems. Summary of the Invention

[0006] To address the technical problem that the user interface and operation process of medical imaging systems are uniformly preset without considering the individual operating habits of operators, this application provides a scanning control method, a scanning control device, and a medical imaging system that support personalized settings by operators.

[0007] According to a first aspect of this application, a scanning control method for a medical imaging system is proposed. The medical imaging system includes a scanner and an interactive device, the interactive device having an interactive interface. The method includes: generating a user-defined instruction in response to a user's custom naming operation on the interactive interface; acquiring a scanning workflow matching the user-defined instruction; displaying a manager of the scanning workflow on the interactive interface, the manager including multiple window areas, at least one window area displaying a custom name; adjusting the sorting or position of the at least one window area to generate a target workflow to achieve personalized settings; and controlling the scanner to execute the target workflow to complete the imaging operation on the object to be detected.

[0008] Optionally, adjusting the sorting or position of at least one window area to generate the target workflow includes: in response to a user using a shortcut key to operate the interactive device, adjusting the position or order of at least one window area to generate the target workflow; or, in response to a user issuing a voice command to the interactive device, adjusting the position or order of at least one window area to generate the target workflow; or, in response to a user dragging at least one window area on the interactive interface to change the position or order of the window areas to generate the target workflow.

[0009] Optionally, the scanning workflow includes multiple subtasks, and the method further includes, before generating the target workflow, obtaining user habit information and determining the acquisition path or execution order of the subtasks based on the habit information.

[0010] Optionally, the method also includes: displaying a window area or target workflow with a custom name and sharing it with other users.

[0011] Optionally, user-defined instructions include at least one of the following: workflow name, manager theme for scanning workflows, and manager style for scanning workflows.

[0012] According to a second aspect of this application, a scanning control device for a medical imaging system is provided, comprising: a database storage unit for storing multiple scanning protocols; an interaction unit for supporting user-inputted custom naming operations and generating user-defined instructions; a personalization unit for determining a matching scanning workflow in the database storage unit based on the user-defined instructions, the scanning workflow comprising a sequential combination of multiple scanning protocols; a manager for controlling the interaction unit to display the scanning workflow, the manager comprising multiple window areas; for adjusting the sorting or position of at least one window area to generate a target workflow; and for controlling the scanner of the medical imaging system to execute the target workflow.

[0013] Optionally, the scanning workflow includes multiple subtasks. Correspondingly, the device also includes an optimization unit for acquiring user habit information and determining the acquisition path or execution order of the subtasks based on the habit information.

[0014] According to a third aspect of this application, a medical imaging system is provided, comprising: a scanner for performing medical imaging scans; an interactive device having an interactive interface; and a processor having executable instructions stored in a non-transitory memory of the medical imaging system, the executable instructions causing the processor to perform the following operations when executed: generating user-defined instructions in response to a user's custom naming operation on the interactive interface; acquiring a scan workflow matching the user-defined instructions; controlling the interactive interface to display a manager of the scan workflow, the manager including multiple window areas, and at least one window area displaying a custom name; adjusting the sorting or position of the at least one window area to generate a target workflow to achieve personalized settings; and controlling the scanner to execute the target workflow to complete the imaging operation on the object to be detected.

[0015] The beneficial effects of this application are as follows: By allowing users to customize naming operations on the interactive interface, user-defined instructions are generated, and a scanning workflow matching these instructions is obtained. Users can easily customize the interface window according to their own needs, operating habits, and understanding of different tasks. A scanning workflow manager is displayed on the interactive interface, comprising multiple window areas, at least one of which displays a custom name. The user-renamed operation interface window is more intuitive to identify, reducing errors. Adjusting the sorting or position of at least one window area generates a target workflow to achieve personalized settings, fully considering user operating preferences in different scenarios and supporting customized interface interaction methods. The scanner is controlled to execute the target workflow to complete the imaging operation of the object being detected, achieving efficient and accurate medical imaging scanning and improving the user experience. This application overcomes the shortcomings of traditional work systems where the interface and operation process are uniformly preset, neglecting the personalized operating habits of operators, and solves the problem of operators spending a lot of time searching for target protocol packets in the system interface, resulting in low work efficiency.

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] The design philosophy of existing medical imaging systems mostly focuses on versatility and stability, but rarely considers the personalized needs of users. The professional software or operating systems of common medical imaging systems are almost all pre-set by manufacturers according to standard procedures: a unified overall architecture of the user interface, a unified layout of operation buttons, unified default names for windows, and unified function shortcuts, leaving users with almost no room for independent customization. Especially for magnetic resonance imaging systems, the protocol manager, as the core operation window, usually uses a uniform and unremarkable name. In a sea of ​​windows with similar names, operators feel like they are searching for a needle in a haystack, requiring complete concentration and meticulous examination each time, easily leading to visual fatigue and wasted time. The arrangement of operation windows in an enterprise is also fixed. No matter how frequently an operator uses certain protocol packets, their initial position in the taskbar or task switcher cannot be changed. This causes frequently used windows to be buried behind numerous infrequently used windows, forcing operators to repeatedly scroll the mouse wheel or press the switch key multiple times to find the target, making the operation cumbersome and overwhelming. Furthermore, manufacturers offer very few pre-defined shortcut combinations, and these are based on their own assessment of the importance of functions, without considering the frequency and preferences of users in actual work. Even if users find certain operations frequently performed and urgently need convenient shortcuts, they are often forced to follow a fixed shortcut pattern that is not suitable for them, complicating simple operations and significantly reducing work efficiency. This kind of work system design, lacking flexibility and human-centered consideration, has become a heavy shackle hindering the development of various industries in today's era of pursuing efficiency, precision, and personalization, and urgently needs to be broken.

[0027] This application constructs a user-centric, real-time, multi-dimensional customizable workflow system with a simple and smooth operation process, bringing great convenience to users. The workflow starts with custom window naming, allowing users to name key windows according to their preferences. The medical imaging system immediately uses an intelligent window association algorithm to accurately bind the name to the corresponding window. At the same time, with the help of real-time multi-area holographic synchronous display and update technology, the new name appears in all visible areas, allowing technicians or doctors to find frequently used windows at a glance. Furthermore, users specify the priority of frequently used windows, and the system's intelligent priority dynamic optimization algorithm adjusts the window order in real time based on operation data, ensuring that frequently used windows are always in the most conspicuous and easily accessible positions for quick switching. Entering the operation interaction customization stage, in addition to conventional shortcut key settings, it also integrates cutting-edge interaction technologies such as gestures, voice, and eye tracking. The system deeply learns user habits, anticipates operations in advance, and achieves near-zero latency interaction.

[0028] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] This application proposes a scanning control method for a medical imaging system, which can operate on the medical imaging scanning system to perform medical imaging scans on patients. Figure 1 As shown, the medical imaging system includes a scanner 102, an interactive device 104, a processor 106, and a non-transient computer-readable storage medium 108. The medical imaging scanning system can perform scans and acquire single-modal images such as X-ray images, computed tomography (CT) images, magnetic resonance imaging (MR) images, positron emission tomography (PET) images, and single-photon emission computed tomography (SPECT) images, and can also acquire mixed images of at least two of the aforementioned modalities. The scanner 102 and the interactive device 104 can be connected to the processor 106 via a network. Alternatively, the scanner 102 and the interactive device 104 can be directly connected to the processor 106.

[0030] Scanner 102 is used to perform scanning on a target object or to perform medical imaging scans. Corresponding to the acquisition of MR images by a medical imaging scanning system, scanner 102 is an MR scanning device composed of a superconducting magnet, gradient coils, and radio frequency coils. Corresponding to the acquisition of CT images by a medical imaging scanning system, scanner 102 is a CT scanning device composed of a gantry and an X-ray tube and detector mounted on the gantry, both of which can rotate around the gantry. Furthermore, the CT scanning device may include one set of X-ray tubes and CT detectors, or two sets of X-ray tubes and detectors. The type of CT detector can be a gas detector, a scintillation detector, a rare-earth ceramic detector, or a gemstone detector, etc. Corresponding to the acquisition of PET images by a medical imaging scanning system, scanner 102 is a PET scanner composed of a gantry and a PET detector mounted on the gantry. The type of PET detector can be a photomultiplier tube (PMT), a silicon photomultiplier tube (SiPM), or a digital photon counter (DPC), etc.

[0031] Interactive device 104 is configured to receive user input, which can be voice, text, scan upload, touch, or mouse clicks. User input can be used to define one or more combinations of workflow name, scan workflow manager theme, and scan workflow manager style. Interactive device 104 may include mobile devices, tablets, laptops, or combinations thereof. Optionally, interactive device 104 may include input devices, output devices, etc. Optionally, interactive device 104 may be part of scanner 102. Interactive device 104 has an interface display function. Optionally, the interactive interface of interactive device 104 can display the scan workflow manager. The upper part of the interactive interface can display a patient management button, a patient registration icon, patient tags, a workspace, a system status bar, a navigation bar, and a system toolbar. Through the interactive interface, functions such as patient registration, patient management, examination, image browsing, and film printing can be realized. If interactive device 104 is selected to have dual screens, different applications can be loaded and displayed on different screens.

[0032] For example, clicking the patient management button will take you to the patient management interface. This interface can be divided into sections such as a data management area, an examination list area, a sequence information area, a sequence list / report area, a navigation bar, and an image preview area. Specifically: the data management area not only provides data source switching, data keyword search, and date filtering functions, but also offers data archiving, importing, protecting, splitting, merging, modifying, and deleting operations; the examination list area displays all examinations that meet the search criteria; the sequence information area displays relevant information for the selected sequence; the sequence list / report area displays the sequences and reports from the selected examination; the navigation bar serves as the application entry point, loading the selected data into the corresponding application; and the image preview area displays a list of images and thumbnails of the selected sequence.

[0033] The examination interface can be accessed from the patient management interface. This interface includes sections such as a graphical positioning window, an examination list area, a parameter card area, a scan monitoring window, a time progress display area, and a physiological signal display area. The graphical positioning window displays reference images of different sections for image browsing and slice localization. The examination list area displays loaded protocols. Buttons in the parameter card area allow switching between parameter cards and protocol selection areas. The scan monitoring window displays the reconstructed scan images in real time, controls the scan progress, and displays safety monitoring information.

[0034] After the user performs a custom naming operation on the interactive interface of the interactive device 104, the processor 106 generates user-defined instructions. The processor 106 acquires a scanning workflow that matches the user-defined instructions, and the scanning workflow is the sequential execution order of multiple subtasks. The processor 106 controls the interactive interface to display the scanning workflow manager. The window area of ​​the interactive interface can correspond to a subtask. The window area of ​​the interactive interface can be the data management area, examination list area and sequence information area, sequence list area / report area, navigation bar and image preview area of ​​the aforementioned patient management interface, or the graphical positioning window, examination list area, parameter card area, scan monitoring window, time progress display area and physiological signal display area of ​​the examination interface. The window area of ​​the interactive interface can display custom names. After the user adjusts the sorting or position of the window area, the processor 106 generates the target workflow to realize personalized settings. The processor 106 controls the scanner 102 to execute the target workflow to complete the imaging operation on the object to be detected.

[0035] Optionally, the scanning workflow may include the order in which different scanning parameters are adjusted to achieve a target scanning function. Scanning parameters can be one or more combinations of parameters such as field of view (FOV), number of slices, readout resolution, phase resolution, oversampling, slice thickness, spacing, bandwidth, echo time (TE), repetition time (TR), echo train length, flip angle (FA), number of excitations (NEX), number of repetitions, invert time (TI), b-value, T1ρ preparation duration, T2 preparation duration, velocity encoding (VENC) value, acceleration factor, saturation band, fat suppression pulse parameters, and reconstruction-related parameters. For example, during the technician's parameter adjustment process, a method based on a large language model can be used: after the first scanning parameter is adjusted, the technician is reminded in real time of the next one or more scanning parameters that need adjustment to achieve the best imaging effect.

[0036] Let's take an MR imaging system as an example from a medical imaging system. Figure 2The main magnet 201 is configured to generate a main magnetic field. The main magnet 201 can also be configured or used to control the uniformity of the generated main magnetic field. A gradient coil 202 can be located inside the main magnet 201. The gradient coil 202 can generate a field called a gradient field. The gradient coil 202 can include an X coil, a Y coil, and / or a Z coil. For example, the Z coil can be designed according to a circular coil configuration, while the X and Y coils can be designed according to a saddle-shaped coil configuration. The three sets of coils can be configured or used to generate three different magnetic fields for position encoding. The gradient coil 202 can be configured or used to allow spatial encoding of the MR signal for image construction. The gradient coil 202 can be connected to one or more of an X gradient amplifier 204, a Y gradient amplifier 205, or a Z gradient amplifier 206. One or more of the three amplifiers can be connected to a waveform generator 216. The waveform generator 216 can be configured or used to generate gradient waveforms applied to the X gradient amplifier 204, the Y gradient amplifier 204, and / or the Z gradient amplifier 204. The amplifiers can be configured or used to amplify the waveforms. The amplified waveform can be applied to one of the coils in gradient coil 202 to generate gradient fields along the X, Y, and Z axes, respectively. Gradient coil 202 can be used in a closed-aperture MRI scanner. The gradient power amplifier energizes all three sets of coils in gradient coil 202, thereby generating gradient fields in three directions.

[0037] Radio Frequency (RF) coil 203 can be configured or used to generate an RF field, which is used to generate MR signals for image construction. RF coil 203 may include a transmitting coil and a receiving coil. RF coil 203 can be connected to RF electronics 209, which can be configured or used as one or more integrated circuits functioning as waveform transmitters and / or waveform receivers. RF electronics 209 can be connected to RF amplifier 207 and analog-to-digital converter (ADC) 208. Waveform generator 216 can generate RF signals. The RF signals can first be amplified by RF amplifier 207, processed by RF electronics 209, and applied to RF coil 203 to generate an RF field. Waveform generator 216 can generate a series of RF waveforms periodically or irregularly. For example, waveform generator 216 can generate a single excitation RF pulse with a deflection angle of 90° and multiple refocusing RF pulses with a deflection angle of 180°. Note that the excitation RF pulse can have a deflection angle other than 90°, for example, any deflection angle ranging from 0° to 180°.

[0038] The console 214 may include an input device, a control panel, etc. The input device may be a keyboard, touchscreen, mouse, remote controller, etc., or any combination thereof. The image display 212 is connected to the console 214 and has an interactive interface. The image display 212 has a graphical user interface / interactive interface, displaying interactive elements such as text input boxes, drop-down menus, and buttons, allowing users to perform custom naming operations. Users can perform custom naming operations on the interactive interface. The console 214 generates user-defined instructions based on these operations and obtains a scanning workflow matching the user-defined instructions. The scanning workflow may include multiple different stages or tasks, each performed in its own window area. Users can adjust the order or position of one or more window areas according to their usage habits or specific needs. For example, users can move frequently used function window areas to more easily accessible locations or adjust the display order of the window areas to suit their operating habits. In this way, the medical imaging system generates a target workflow optimized for a specific user.

[0039] A scanning workflow may include the order in which different scanning parameters are adjusted to achieve a target scanning function. Scanning parameters may be one or more of the following combinations: field of view, number of slices, readout resolution, phase resolution, oversampling, slice thickness, interslice spacing, bandwidth, echo time, repetition time, echo train length, flip angle, number of excitations, number of repetitions, inversion time, b-value, T1ρ preparation duration, T2 preparation duration, velocity encoding value, acceleration factor, saturation band, fat suppression pulse parameters, reconstruction-related parameters, etc.

[0040] During the execution of the target workflow, waveform generator 216 can generate drive signals for gradient coil 202 and drive signals for the transmitting coil of RF coil 203. The receiving coil of RF coil 203 can receive the magnetic resonance signal generated by the detected object. The magnetic resonance signal is then sent to RF electronics 209 and transmitted to ADC 208 for digitization. The magnetic resonance signal can be demodulated and filtered in electronics 209. Subsequently, the magnetic resonance signal can be processed by image processor 211 to generate one or more images.

[0041] CPU 213 can be configured or used to control the generation of waveforms in waveform generator 216 and the generation of images in image processor 211. CPU 213 can be a central processing unit, application-specific integrated circuit, application-specific instruction set processor, graphics processor, physical processor, microcontroller unit, digital signal processor, field-programmable gate array, ARM, etc., or any combination thereof.

[0042] Data storage 215 can be configured or used to store received MR signals. When an MRI scan is completed, all data of the scanned object (e.g., tissue, body, or specific part) is obtained. A Fourier transform of the data can be performed by, but is not limited to, CPU 213, image processor 211, etc., or any combination thereof. After the transform is completed, one or more desired images can be generated. The images can be stored in data storage 215. The images can be further transmitted to image display 212 for display. A shim controller 210 can be used to control the homogeneity of the main magnetic field and the main magnetic field generated by the shim coil 201.

[0043] This application proposes a scanning control method for a medical imaging system, such as... Figure 3 As shown, the method includes the following steps:

[0044] Step S301: In response to the user's custom naming operation on the interactive interface, a user-defined instruction is generated. Users can perform custom naming operations through input boxes or menu options on the interactive interface of the interactive device 104. Users can be various types of clients, such as clinicians, medical device R&D engineers, researchers from research institutions, or radiology technicians. For example, users can name a "code writing" task "My Code Task" or a "document review" task "Report Review" using text. This custom naming method is not only intuitive but also helps users quickly identify task content, reducing the possibility of misoperation. Alternatively, users can send tasks to the interactive interface of the interactive device 104 via voice, and the interactive device 104 will automatically complete the task input, improving operational convenience. For another example, a radiology technician can specify a descriptive name, such as "Emergency Chest Scan" or "Pediatric Low-Dose Head Scan," to facilitate the identification and management of different user tasks.

[0045] Step S303: Obtain the scanning workflow matching the user-defined command. The medical imaging system retrieves a matching scanning workflow from a pre-set scanning workflow database based on the information contained in the user-defined command. The matching process can be based on keyword matching, semantic analysis, or user history operation records. For example, when the user enters the custom name "routine chest scan," the medical imaging system will search for workflow templates related to chest scans and further filter out standard chest scan workflows based on the qualifier "routine."

[0046] The scanning workflow manager's theme can be selected or customized by the user. For example, users can set the visual theme to dark mode, high contrast mode, or minimalist mode to suit different usage environments and personal visual preferences. The layout style of the scanning workflow manager can be selected by the user, such as grid layout, list layout, or flowchart layout, to optimize information display and workflow. The icons of the scanning workflow manager can be customized, such as set to polygons, lines, icons + text, text buttons, icon buttons, etc. Through these customization options, users can create highly personalized scanning workflows, improving operational efficiency and user experience.

[0047] Step S305: The scanning workflow manager is displayed on the interactive interface. This manager includes multiple window areas, at least one of which displays a custom name. The scanning workflow manager visually presents the various components and execution order of the scanning workflow. The multiple window areas in the manager can correspond to different stages or tasks in the scanning workflow, such as patient information entry, scanning parameter settings, image reconstruction, and post-processing. The medical imaging system will display the user-entered custom name in at least one window area, allowing the user to intuitively identify the currently operating scanning workflow.

[0048] The scanning workflow also includes implementing the adjustment sequence of different scanning parameters within a target scanning function. After the first scanning parameter is adjusted, the technician is reminded in real time of the next one or more scanning parameters that need adjustment to achieve the best imaging effect. For example, for the TI_FSE protocol, technicians often adjust the number of slices to cover the lesion area, but this adjustment often leads to an excessive increase in TR. The technician wants to improve T1 contrast but ends up with T2 contrast instead. The scanning workflow could be: after the user adjusts the number of slices, a pop-up window in the interactive interface reminds the user to increase the number of segments, thereby ensuring that TR remains as constant as possible. For example, the scanning workflow could be: when the FSE protocol enables IR function to implement FLAIR function, if the number of segments is set to 1, the user is reminded to change it to 2 or higher, otherwise it will affect the FLAIR pressure effect. Another example is: when the user drags the protocol from one area to scan other areas, the user is reminded to change the transmission mode to the corresponding area. Or, the scanning workflow could be: when the user reduces the readout resolution of DWI, the user is reminded that the TE value can be shortened to obtain better image quality. For example, a scanning workflow could be such that when the echo mode of a QUICK 3D WFI sequence is changed from single excitation to multiple excitations, the user is alerted to reduce bandwidth for better performance.

[0049] The adjustment order of different scanning parameters can be implemented using a large language model-based method. In this embodiment, the large language model adopts a Transformer network architecture. Its training method includes: acquiring a large number of factory-issued scanning protocols and numerous installation site scanning protocols; listing the scanning parameters of multiple scanning protocols in the order of the entire sequence, specifically grouping scanning parameters with similar functions together as much as possible to make the attention mechanism work more effectively; masking scanning parameters that are not in the current sequence or whose functions are not enabled in the current sequence; and then labeling the masked categorized scanning parameters, i.e., labeling the next one or more scanning parameters in the categorized scanning parameter adjustment process, for Transformer training and fine-tuning, ultimately enabling Transformer to complete the recommended adjustment order of scanning parameters.

[0050] The following is an example of a scanning protocol according to an embodiment of this application. The scanning parameters of this scanning protocol are divided into various types, such as basic information, geometric parameters, contrast parameters, magnetization preparation parameters, and reconstruction parameters.

[0051]

[0052] Existing MRI scanning protocols typically include dozens of adjustable scanning parameters, and the application scenarios for these parameters may vary depending on the body part or population. For clinical technicians, memorizing the use of numerous sequences, scenarios, and scanning parameters presents a significant challenge. In practice, this often leads to a lack of complete understanding of the function or overall functionality during parameter adjustment, resulting in an inefficient or incorrect protocol. The embodiments of this application can provide real-time reminders to technicians during parameter adjustment to indicate the next or subsequent parameter values ​​that need adjustment, thereby achieving optimal imaging results.

[0053] Step S307 involves adjusting the sorting or position of at least one window area to generate a target workflow for personalized settings. Users can adjust the sorting or position of the window areas according to their usage habits or specific needs. For example, users can move frequently used function windows to more easily accessible locations or adjust the display order of the window areas to suit their operating habits. In this way, the medical imaging system generates a target workflow optimized for a specific user.

[0054] The medical imaging system supports multi-subtask execution. When a scanning workflow involves multiple subtasks, users can prioritize each subtask based on its urgency or importance. The medical imaging system will adjust the display order of subtasks in the task list or execution interface according to the set priorities, ensuring that high-priority subtasks are processed quickly by the user. Users can choose to switch or execute subtasks using shortcut keys, mouse gestures, or voice commands, among other methods. This variety of execution methods not only enhances operational flexibility but also meets the operational needs of different users in different scenarios. For example, users can select specific shortcut key combinations to switch tasks on the interactive interface of the interactive device 104.

[0055] In one implementation, adjusting the order or position of window areas to generate a target workflow can be achieved as follows: in response to a user using keyboard shortcuts to operate the interactive device, the position or order of at least one window area is adjusted, generating the target workflow. The medical imaging system can preset a series of keyboard shortcut combinations for quickly adjusting the position or order of window areas. For example, a user can use "Ctrl + arrow keys" to move a selected window area, or use "Alt + number keys" to adjust the display order of the window areas. This method is particularly suitable for professional users familiar with system operation and can improve work efficiency.

[0056] In another implementation, in response to a user issuing a voice command to the interactive device, the position or order of at least one window area is adjusted to generate the target workflow. The medical imaging system integrates voice recognition functionality, enabling it to recognize and execute user voice commands. For example, a user can adjust the window areas using voice commands such as "[move the parameter setting window to the left]" or "[switch the order of the image reconstruction and post-processing windows]". This approach allows users to adjust the workflow even when they cannot directly operate the interactive interface (e.g., when their hands are engaged in other tasks).

[0057] In another implementation, the target workflow is generated in response to a user dragging at least one window area on the interactive interface to change the position or order of the window areas. This is an intuitive operation method, allowing users to directly drag window areas to the desired position using a mouse or touch operation. The medical imaging system displays the dragging effect in real time and updates the window area arrangement after user confirmation. This method is simple to operate and suitable for all types of users.

[0058] The medical imaging system also supports intelligent optimization. It collects user operating habits through the interactive device 104, automatically analyzes these habits, and adjusts the execution priority and order of tasks. For example, if the system detects that the user is frequently switching between coding and document review tasks, it will automatically increase the priority of these two tasks and optimize the execution path to ensure the user can complete multitasking in the most efficient way.

[0059] Medical imaging systems can acquire user habit information through various means, including but not limited to: analyzing user history records to identify commonly used operating patterns and preferences; soliciting user feedback on usage habits and preferences through questionnaires or settings interfaces; and automatically learning and inferring user habits based on user behavior using machine learning algorithms. This habit information may include preferred window layouts, commonly used scanning parameters, and operating sequences.

[0060] Based on user habits, the acquisition path or execution order of subtasks can be determined. Medical imaging systems intelligently adjust the acquisition path or execution order of each subtask in the scanning workflow based on the acquired user habit information. For example, when the medical imaging system detects that a user typically sets scanning parameters before entering patient information, it will adjust the default order of subtasks accordingly; when the medical imaging system detects that a user frequently uses certain parameter combinations, it will prioritize displaying those parameter setting options. This user habit-based optimization can improve operational efficiency and reduce unnecessary operational steps.

[0061] Step S309: Control the scanner to execute the target workflow to complete the imaging operation on the object to be detected. The medical imaging system converts the user-customized target workflow into a sequence of instructions that the scanner can execute, and controls the scanner to perform the scanning operation according to these instructions. During the scanning process, the medical imaging system automatically adjusts various settings of the scanner, such as scanning range, slice thickness, tube voltage, and tube current, according to the parameters and procedures defined in the target workflow, to ensure that the scanning results meet the expected requirements.

[0062] User-defined named window areas or target workflows can be shared with other users. For example, users can share their customized workflows with other users within the same healthcare institution or upload them to a cloud platform for wider user access. When shared, the medical imaging system retains the user's custom naming and window arrangement to ensure other users can understand and correctly use the workflow. This sharing mechanism helps promote efficient workflows and facilitates collaboration and experience sharing within healthcare teams.

[0063] The scanning control method of the medical imaging system in this application grants users the authority to customize their workflows, allowing them to deeply optimize the system based on their expertise and daily operating habits. It provides a custom window naming function, enabling users to assign personalized names to key windows. The system's intelligent association engine responds quickly and accurately binds the names to the windows corresponding to the scanning workflow manager. Simultaneously, it provides a real-time multi-area synchronous display and update mechanism, instantly updating the window names in all visible areas such as the taskbar, window switching interface, and system tray. No matter where the operator views the system, they can easily locate their frequently used windows, greatly reducing window search time and making the operation process smoother and more efficient. It also provides a window priority setting function, allowing users to prioritize frequently used windows. When a window is set to be displayed first, the system's built-in intelligent priority algorithm immediately activates, dynamically adjusting the order of all windows to ensure that this window is always prominently displayed on the front. Whether switching between windows by clicking the taskbar or using shortcut keys, users can quickly get to the core of their work, further improving work efficiency. In addition, to fully meet the diverse operating habits of users, the system supports customization from regular shortcut keys to complex multi-key combinations and even cutting-edge interaction methods such as gesture recognition. The advanced interaction recognition system uses deep learning to predict user habits and achieves near-zero latency interaction, significantly reducing the error rate. This comprehensively creates a convenient, efficient, and personalized workflow for users, greatly improving their work comfort and sense of control.

[0064] In one embodiment, taking a medical device R&D engineer or a researcher in a research institution as an example, this type of user is similar to a software developer, frequently switching between tasks such as coding, documentation, and code testing in their daily work. The scanning control method of a medical imaging system, such as... Figure 4 As shown, it includes the following steps:

[0065] Step S401: In response to the user's custom naming operation on the interactive interface, a user-defined instruction is generated. In this embodiment, the user names the "code writing" task as "My Code Task" and the "documentation writing" task as "Project Documentation" through text input on the interactive interface, and sets both tasks to high priority.

[0066] Step S403: Obtain the test workflow that matches the user-defined instruction. The medical imaging system retrieves the matching workflow from a preset workflow database based on the information contained in the user-defined instruction. The matching process can be based on keyword matching, semantic analysis, or user history operation records. In this embodiment, the workflow manager theme can be selected or customized by the user. For example, the user can set the visual theme of the test workflow manager to dark mode, high contrast mode, or minimalist mode to adapt to different usage environments and personal visual preferences. The layout style of the test workflow manager can be selected by the user as a grid layout, list layout, or flowchart layout to optimize information display and operation flow. The icons of the test workflow manager can be customized, such as set to polygons, lines, icons + text, text buttons, icon buttons, etc. Through these customization options, users can create highly personalized test workflows, improving operational efficiency and user experience.

[0067] Step S405: The test workflow manager is displayed on the interactive interface. This manager includes multiple window areas, at least one of which displays a custom name. The test workflow manager visually presents the various components and execution order of the scanning workflow. The multiple window areas in the manager can correspond to different stages or tasks in the scanning workflow, such as scanning parameter settings, code testing, post-processing, etc. The medical imaging system will display the user-entered custom name in at least one window area, allowing the user to intuitively identify the currently operating test workflow.

[0068] Step S407: Adjust the sorting or position of at least one window area to generate the target test workflow to achieve personalized settings.

[0069] In this embodiment, the medical imaging system can collect the user's operating habits through the interactive device 104. The medical imaging system automatically analyzes the collected operating habits and automatically adjusts the execution priority and order of tasks. If the medical imaging system detects that the user is frequently switching between code writing and document review tasks, it will automatically increase the priority of these two tasks and optimize the execution path to ensure that the user can complete multitasking operations in the most efficient way.

[0070] Based on user habits, the acquisition path or execution order of subtasks can be determined. Medical imaging systems intelligently adjust the acquisition path or execution order of each subtask in the scanning workflow based on the acquired user habit information. For example, when the medical imaging system detects that a user typically sets scanning parameters before entering patient information, it will adjust the default order of subtasks accordingly; when the medical imaging system detects that a user frequently uses certain parameter combinations, it will prioritize displaying those parameter setting options. This user habit-based optimization can improve operational efficiency and reduce unnecessary operational steps.

[0071] Step S409: Control the scanner to execute the target test workflow to acquire imaging results, and obtain code test results based on the imaging results. In this embodiment, if the imaging results meet the requirements, the code test result is passed. If the imaging results do not meet the requirements, the code test result is failed. The user then performs code modification, document modification, and code testing tasks again.

[0072] In one embodiment, the user is a radiology technician. The user's daily work revolves around performing accurate scans for patients, a key step of which is opening the protocol manager and selecting the appropriate protocol from numerous options to ensure the accuracy and validity of the scan results. Figure 5 As shown, the scanning control method of the medical imaging system includes:

[0073] In step S501, after the technician performs a custom naming operation on the interactive interface, the processor generates a user-defined instruction. In this embodiment, when the technician decides to customize the name of the interface window, the technician can enter the user's name as the new name through a custom naming entry specifically provided by the medical imaging system. At this time, the medical imaging system accurately associates the user's name with the corresponding protocol manager window and updates it synchronously in real time in various display areas such as the taskbar and window switching interface of the protocol manager window. Thus, the protocol manager window is marked with a unique and intuitive identifier.

[0074] In step S503, the technician adjusts the window area sorting to generate the first target workflow, setting the display position and order of the window areas. The technician understands that quickly locating frequently used protocol managers is crucial in busy daily scanning work. The technician can easily set the protocol manager named after the user as the first priority in the system's priority settings interface. This ensures that this window is prominently displayed at the forefront, whether viewed in the taskbar or when switching windows, greatly saving search time. Figure 6 The diagram shown illustrates the interactive interface display result according to an embodiment of this application. Multiple window areas are stacked simultaneously on the interactive interface. The user sets the priority of the first window area to high, and the user sets the priority of the second window area to low. Thus, the first window area is stacked on top of the second window area, meaning it is prioritized for display on the protocol manager's interface.

[0075] In step S505, the user associates the shortcut key operation with the switching of the interactive interface display to set the method when switching between different window areas.

[0076] like Figure 7The diagram illustrates the interactive interface switching according to an embodiment of this application. When switching between different window areas, the technician prefers efficient shortcut key operations. In the shortcut key customization module, the user sets the operation to switch to the high-priority window area in the first target workflow as pressing the "tab" key. Whenever it is necessary to call the protocol package carefully edited by the technician, simply pressing the "tab" key instantly receives the instruction, accurately recognizes this shortcut key operation, and quickly switches the interface to the high-priority window area named the first target workflow. The entire process is smooth and natural, allowing technicians to complete key operations in an extremely convenient and quick way during their daily high-intensity MRI scan work, greatly improving work efficiency and reducing the risk of errors that may be caused by cumbersome operations.

[0077] This application also provides a scanning control device for a medical imaging system, such as... Figure 8 As shown, the device includes a database storage unit 802, an interaction unit 804, and a personalization unit 806.

[0078] Database storage unit 802, the functions of which can be described above Figure 1 The processor 106 in the unit is used to store multiple scanning protocols. This unit contains a structured database for storing various types of scanning protocols. These scanning protocols can be organized according to different classification methods, such as by examination site (head, chest, abdomen, etc.), examination purpose (routine examination, contrast-enhanced examination, functional imaging, etc.), or specific population (adults, children, the elderly, etc.). Each scanning protocol contains detailed scanning parameter settings, such as scan range, slice thickness, tube voltage, tube current, reconstruction algorithm, etc. The database storage unit also supports version management of scanning protocols, recording information such as the protocol's creation time, modification history, and usage frequency.

[0079] Interaction unit 804, the functions of which can be described above Figure 1 The interactive device 104 supports user-input custom naming operations and generates user-defined instructions. The interactive unit 804 provides a graphical user interface, including text input boxes, drop-down menus, buttons, and other interactive elements, allowing users to perform custom naming operations. Users can create personalized names for the scanning workflow through the interactive unit 804, such as "Dr. Zhang's routine chest scan plan." The interactive unit 804 receives user input and converts it into user-defined instructions recognizable by the medical imaging system. These instructions include the user-input custom name and related configuration information. The interactive unit 804 also provides real-time feedback, such as input validation and auto-completion functions, improving the accuracy and efficiency of user input. Alternatively, users can send tasks to the interactive interface of the interactive device 104 via voice, allowing the interactive device 104 to automatically complete the task input, enhancing operational convenience.

[0080] Personalization unit 806, whose functions can also be described above. Figure 1 The processor 106 in the system performs tasks to determine the matching scan workflow in the database storage unit based on user-defined instructions. This scan workflow contains a sequential combination of multiple scan protocols. The personalization unit 806 implements an intelligent matching algorithm, analyzes key information in the user-defined instructions, and retrieves relevant scan protocols from the database. The matching process considers various factors, including text similarity, semantic relevance, and user historical preferences. After finding matching scan protocols, the personalization unit 806 combines these protocols into a complete scan workflow in a logical order. For example, for the user-defined instruction of "chest enhancement scan," the personalization unit combines the plain scan protocol and the enhancement scan protocol to form a complete chest enhancement examination workflow.

[0081] The personalization unit 806 also controls the interaction unit 804 to display the scanning workflow manager, which includes multiple window areas. The manager visually displays the structure and content of the scanning workflow, with each window area corresponding to a functional module or step within the workflow. The layout and design of the window areas consider human-computer interaction principles, ensuring clear and readable information and simple, intuitive operation. The manager supports multiple view modes, such as list view, flowchart view, or timeline view, and users can switch between different view modes as needed. For example, users can set the visual theme of the scanning workflow manager to dark mode, high-contrast mode, or minimalist mode to adapt to different usage environments and personal visual preferences. The layout style of the scanning workflow manager can be selected by the user as a grid layout, list layout, or flowchart layout to optimize information display and operational flow. The icons of the scanning workflow manager can be customized, such as set to polygons, lines, icons + text, text buttons, icon buttons, etc. Through these customization options, users can create highly personalized scanning workflows, improving operational efficiency and user experience.

[0082] The personalization unit 806 is also used to adjust the sorting or position of at least one window area to generate a target workflow. The personalization unit provides window area management functionality, allowing for adjustments to the sorting or position of window areas. Adjustments can be made in various ways, such as drag-and-drop operations, keyboard shortcuts, or context menu options. The personalization unit records the user's adjustments and updates the manager's display in real time. After the adjustments are complete, the personalization unit generates a new target workflow that retains the core functionality of the original scanning protocol while reflecting the user's personalized arrangement preferences.

[0083] The personalization unit 806 also controls the scanner of the medical imaging system to execute the target workflow. The personalization unit 806 translates the target workflow into a sequence of commands executable by the scanner and sends these commands to the scanner via the medical imaging system interface. During scan execution, the personalization unit 806 monitors the scan progress and status to ensure the scan proceeds smoothly according to the predetermined workflow. If any abnormalities occur during the scan, the personalization unit generates an alarm and provides corresponding handling suggestions. After the scan is completed, the personalization unit 806 collects the scan results and performance data for subsequent workflow optimization.

[0084] In this embodiment, the scanning workflow includes multiple subtasks. Correspondingly, the scanning control device of the medical imaging system also includes an optimization unit 808. The optimization unit 808 is used to acquire user habit information and determine the acquisition path or execution order of subtasks based on the habit information. The optimization unit 808 implements user behavior analysis functions, identifying user usage habits and preference patterns by recording and analyzing the user's operation history. The analysis content includes, but is not limited to: commonly used operation sequences, frequently accessed functional modules, and preferred parameter settings. The optimization unit can also directly acquire the user's explicitly expressed habit preferences through user feedback questionnaires or settings interfaces.

[0085] Based on acquired habit information, the optimization unit 808 uses intelligent algorithms to determine the optimal acquisition path or execution order of subtasks. For example, if analysis reveals that users typically view historical patient images before setting new scan parameters, the optimization unit will adjust the default order of subtasks accordingly. If users frequently need to access certain specific parameter settings, the optimization unit will optimize the access paths for these settings, reducing the number of operation steps. The optimization unit's adjustments are dynamic and continuously updated as user habits change, ensuring that the medical imaging system always maintains the most suitable operating flow for the current user.
