[0057] In related technologies, CBCT electronic image reporting systems have limited functionality. Artificial intelligence models use two-dimensional images (e.g., panoramic or lateral views) to identify and analyze lesions to generate corresponding medical image reports. Furthermore, the image reports are limited in content, lacking high-resolution images of lesion sites or suspected lesion sites. Doctors often struggle to verify the accuracy of lesion images in the reports, frequently requiring manual modification or reconstruction, which is tedious, time-consuming, and labor-intensive. Additionally, DICOM front-end processors and cloud services are required for image interpretation. Moreover, the artificial intelligence models used for lesion identification and classification cannot self-iterate or self-learn, making the process of updating these models cumbersome and time-consuming. Therefore, this disclosure provides an image report generation method, apparatus, device, storage medium, and system.

[0058] This disclosure is applicable to various medical scenarios, such as oral and maxillofacial surgery.

[0059] The following text combines Figures 1 to 8 The specific embodiments of this disclosure will be described in detail.

[0060] Figure 1 A flowchart illustrating an image report generation method in some embodiments of this disclosure is shown. See also Figure 1 As shown, the image report generation method S10 of this disclosure may include:

[0061] Step S12: Obtain the three-dimensional volume data, reconstructed geometric parameters, and two-dimensional projection data of the first object from CBCT;

[0062] The first target is the object being imaged by CBCT. For example, it can be, but is not limited to, parts of the human body that require medical imaging, such as the oral cavity, skull, ears, nose and throat, and teeth.

[0063] CBCT performs a circular digital radiograph around the first object to obtain two-dimensional projection data of the first object. The CBCT host then performs three-dimensional reconstruction on the two-dimensional projection data obtained after multiple (e.g., 180-360) digital radiographs around the first object based on the reconstruction geometry parameters to obtain three-dimensional volume data. This three-dimensional volume data is then rendered to form a visualized three-dimensional image of the first object. In step S12, the CBCT host can directly or indirectly (e.g., via cloud service adapter 1400) transmit the unrendered three-dimensional volume data, the obtained two-dimensional projection data, and the corresponding reconstruction geometry parameters to the cloud server.

[0064] Here, the two-dimensional projection data from CBCT may include, but is not limited to, 360° two-dimensional projection data of the first object. The two-dimensional projection data may be, but is not limited to, raw image data format (RAW data format). The three-dimensional volume data may be, but is not limited to, Digital Imaging and Communications in Medicine (DICOM) data or other medical image format data.

[0065] Reconstructed geometric parameters are the relevant geometric parameters of the CBCT scanning track. They can describe the geometric relationship between the source, detector, rotation axis, and imaging area in CBCT. The CBCT host can perform three-dimensional reconstruction based on the reconstructed geometric parameters.

[0066] Figure 2 The spatial geometric relationships expressed by the reconstructed geometric parameters are illustrated. For some implementations, see [link to implementation details]. Figure 2 As shown, the reconstructed geometric parameters may include, but are not limited to, the distance between the source and the detector (SID), the distance between the source and the rotation axis (SAD), the detector horizontal offset (uOffset), the detector vertical offset (vOffset), the source horizontal offset (ySrcOffset), and the source vertical offset (zSrcOffset). Figure 2 The rectangular coordinate system xyz in CBCT is the world coordinate system, and the pixel coordinate system uv is the pixel coordinate system of CBCT.

[0067] In some implementations, the CBCT host can upload the three-dimensional volume data, reconstructed geometric parameters, and two-dimensional projection data of the first object to the cloud server through lossless compression, data anonymization, and other methods. This can protect user privacy without causing data distortion, while reducing data transmission bandwidth requirements, improving data utilization, and lowering hardware costs.

[0068] Step S14: Based on the three-dimensional volume data, reconstructed geometric parameters and two-dimensional projection data of the first object, perform region of interest identification and classification to obtain the region of interest information of the first object;

[0069] The region of interest (ROI) is the area corresponding to the automatically identified lesion or suspected lesion. In some implementations, ROI information may include, but is not limited to, the location of the ROI (e.g., the location of the center point of the ROI in a predetermined world coordinate system, which may be a world coordinate system with a preset point of the human body such as the head or face as its origin), dimensions (e.g., the length, width, and height parameters of the ROI in the predetermined world coordinate system), normal vector, name (e.g., the corresponding lesion name), and attributes (e.g., lesion category and lesion description). Here, the normal vector may indicate the cross-section corresponding to the ROI.

[0070] In some implementations, regions of interest (ROIs) can be identified and classified using artificial intelligence (AI) models. For example, an AI model may include a sequentially connected convolutional neural network (CNN) and a multi-label classification network, where the CNN is used to identify the ROI and the multi-label classification network is used to classify it. However, AI models can also be implemented using other types of machine learning models, not limited to CNNs.

[0071] Figure 3 The diagram illustrates the process of region of interest (ROI) identification and classification using an artificial intelligence model. The reconstructed geometric parameters, 2D projection data, and 3D volume data of a first object are processed by a convolutional neural network to obtain multiple visual features of the first object. Each visual feature may include the location, size, and normal vector of a ROI (e.g., a lesion or suspected lesion site on the first object). A multi-label classification network classifies the visual features of the first object obtained by the convolutional neural network, i.e., classifies the ROIs, generating label information for each ROI. This label information may include the ROI's identifier (e.g., lesion name, lesion number, etc.) and attributes (e.g., lesion category, lesion description, etc.).

[0072] In practical applications, artificial intelligence models can be trained using manually labeled samples, or they can be trained using previously obtained confirmed image reports and corresponding raw data (i.e., 3D volume data, 2D projection data, and reconstructed geometric parameters). For example, see... Figure 3 As shown, the AI ​​model can be iteratively updated using confirmed image reports to continuously improve its accuracy in application, thereby enhancing the accuracy of lesion area identification and classification.

[0073] See below Figure 4 As an example, in some implementations, the image report generation method of this disclosure may further include:

[0074] Step S13: Based on the confirmed image report of the first object, the 3D volume data, the reconstructed geometric parameters, and the 2D projection data, update the parameters of the artificial intelligence model to improve its accuracy. This enables the artificial intelligence model to learn and iterate automatically, continuously enhancing its stability and accuracy while achieving automatic image report generation.

[0075] In one implementation, step S13 may include:

[0076] Step a1: Use the confirmation image report of the first object, three-dimensional volume data, reconstructed geometric parameters and two-dimensional projection data to form a new sample for the artificial intelligence model, and update the sample library of the artificial intelligence model with the new sample;

[0077] Step a2: Retrain the artificial intelligence model using the updated sample library to update the parameters of the artificial intelligence model, thereby improving the accuracy of the artificial intelligence model in identifying and classifying lesions.

[0078] Here, methods such as few-shot learning or similar approaches can be used to retrain the AI ​​model based on the updated sample library. This not only updates the parameters of the AI ​​model and continuously improves its accuracy, but also reduces computational complexity and data volume, thereby lowering hardware costs.

[0079] Step S16: Based on the region of interest information, reconstructed geometric parameters and two-dimensional projection data of the first object, perform local section reconstruction to obtain the first report image of the first object;

[0080] In some implementations, the local section reconstruction process may include: reconstructing a two-dimensional section image of the required slice backup based on the location (e.g., center point location), size, normal vector, and two-dimensional projection data of the region of interest (i.e., the lesion area or suspected lesion area) of the first object, thereby obtaining the first report image of the first object. Since a local two-dimensional image is reconstructed instead of a three-dimensional image, the resource consumption during reconstruction can be greatly reduced. Furthermore, due to the lower resource consumption, the goal of quickly and efficiently reconstructing a high-definition image of a local region can be achieved.

[0081] In some implementations, the FDK filter backprojection algorithm can be used to perform local section reconstruction. That is, the FDK filter backprojection algorithm can be used to reconstruct a two-dimensional image using the reconstructed geometric parameters and local section projection data to obtain the first report image of the first object.

[0082] In some implementations, the report illustrations obtained through local section reconstruction (i.e., the first and second report illustrations herein) have a higher resolution than the slice images obtained directly from three-dimensional volume data.

[0083] Typically, a visualized 3D image is first obtained by rendering 3D volume data, and then 2D slices are obtained by directly slicing the 3D image in a certain direction or position. The resulting 2D slices have the same resolution as the 3D image. However, because the reconstruction and rendering of 3D volume data is resource-intensive and related equipment resources are limited, 3D images often have low resolution, resulting in low resolution 2D slices. Such 2D slices often affect the doctor's diagnosis due to insufficient clarity. In this disclosure, however, through local section reconstruction, high-definition section imaging of unclear lesions or suspected lesions can be achieved, improving the resolution of the section images of lesions. This makes the section images of lesions or suspected lesions have a higher resolution than 3D images. Using such section images as illustrations in imaging reports can effectively improve the clarity of lesion-related images in the reports, not only facilitating the diagnosis of lesions for doctors (i.e., the first user below) but also allowing patients (i.e., the second user below) to more clearly and intuitively view the relevant details of the lesions. Experiments have shown that local section reconstruction can improve the resolution of lesion or suspected lesion images in imaging reports from 0.25mm to 0.125mm or 0.06mm.

[0084] Step S18: Generate a confirmation image report for the first object. The confirmation image report for the first object includes a first report illustration to be displayed to the first user, so that the first user can review the confirmation image report for the first object.

[0085] In some implementations, the following text Figure 8 Taking the image report generation system shown as an example, after the cloud server generates the image report to be confirmed for the first subject, it pushes the image report to be confirmed for the first subject to the doctor (i.e., the first user) through the image report review unit. The doctor can access the image report review unit using electronic devices such as computers and mobile terminals through tools such as applications or browsers. The image report to be confirmed for the first subject is displayed to the doctor through the interface of the browser or application. In this way, the doctor can review and revise the image report in real time.

[0086] In some implementations, the generation and display of the image report to be confirmed can also be achieved using the same electronic device. This disclosure does not impose any limitations on this.

[0087] In some implementations, the region of interest information may also include information such as the category (i.e., lesion category) and attributes (e.g., lesion description, lesion name, etc.) of the region of interest. See also Figure 4As shown, the image report generation method of this disclosure may further include: step S15, generating a first text description based on the category and attributes of the region of interest, and adding the first text description to the image report to be confirmed for the first object. Thus, the automatically generated image report to be confirmed can contain both report images and corresponding text descriptions (e.g., diagnostic descriptions of lesions or suspected lesions), providing rich content without requiring manual input by the doctor, further simplifying the doctor's operation.

[0088] In some implementations, the image report review unit can be implemented as a first Web Service deployed on a cloud server. The image report review unit can provide a first webpage to a first terminal. The image report to be confirmed is displayed on the first webpage, which can only be viewed by the first user with image report review permissions. The first user can access the first webpage through a browser using the first terminal, and after logging in and authenticating, can review and revise the image report through the first webpage.

[0089] In some embodiments, the image report generation method of this disclosure may further include: providing a multiplanar reconstruction (MPR) interface, which can be used by a first user and / or a second user to display a visualized 3D image and / or a multiplanar slice image of the corresponding visualized 3D image.

[0090] In some implementations, the image report review unit may have a multiplanar reconstruction (MPR) interface, which can be used to display visualized 3D images, axial section images, sagittal section images, and coronal section images of the first object. The first user can also access a first webpage via a browser using a first terminal, and after logging in and authenticating, view the first webpage. The user can then access the MPR interface by clicking the MPR interface button on the first webpage or by other means to perform a diagnosis by viewing the visualized 3D images, axial section images, sagittal section images, and coronal section images of the first object. The user can also revise the accompanying images in the image report through selection operations on the MPR interface.

[0091] Here, axial, sagittal, and coronal slice images can be obtained directly from the visualized 3D image. This method of obtaining axial, sagittal, and coronal slice images directly from the 3D image reduces equipment wear and performance requirements, and meets the needs of doctors for real-time drag-and-drop viewing without lag.

[0092] Step S11: In response to the confirmation operation of the first user, a confirmation message corresponding to the pending image report of the first object is generated. The pending image report of the first object is marked as the confirmed image report of the first object, and then displayed to the second user. Thus, doctors can automatically generate confirmed image reports by clicking a button, further simplifying the doctor's operation. At the same time, while ensuring the accuracy and reliability of the image report content, the confirmed image report can be pushed online to the patient, effectively simplifying the doctor-patient communication process and improving its efficiency.

[0093] In some implementations, the report images in the confirming image report and / or the image report to be confirmed may record information such as lesion location, size, and normal vector. That is, the first report image in the confirming image report and / or the image report to be confirmed records the corresponding region of interest information, and / or the second report image in the confirming image report and / or the image report to be confirmed records the corresponding selected region information. In this way, patients or doctors can jump to the display interface of the report image by clicking on the report image in the confirming image report, which facilitates doctors to quickly review the image report and patients to quickly view their condition.

[0094] See Figure 4 As shown, the image report generation method S40, in addition to steps S12 to S13 mentioned above, may also include the following steps:

[0095] Step S42: Render a visualized 3D image of the first object using the 3D volume data of the first object, and display the visualized 3D image of the first object to the first user, so that the first user can review the image report to be confirmed of the first object in conjunction with the visualized 3D image of the first object.

[0096] Since 3D reconstruction is resource-intensive, and CBCT already has 3D volume data (i.e., DICOM data) for 3D reconstruction, this disclosure directly uses the DICOM data uploaded by CBCT to render a visualized 3D image of the first object. This eliminates the need to repeatedly perform 3D reconstruction on the entire first object, thereby reducing resource consumption, improving data utilization, and increasing execution efficiency.

[0097] This allows doctors to quickly locate lesions by referring to visualized 3D images, and to perform operations such as modification and confirmation on the images to be confirmed. This not only further improves diagnostic efficiency and simplifies doctors' operations, but also improves diagnostic accuracy.

[0098] It should be noted that the execution order of step S42 and the preceding steps S14 to S13 is not limited. That is, step S42 can be executed simultaneously with, before or after the preceding steps S14 to S13.

[0099] See Figure 4 As shown, the image report generation method S40 may further include the following steps:

[0100] Step S44: Based on the selected area information of the first object, the reconstructed geometric parameters and the two-dimensional projection data, perform local section reconstruction to obtain the second report map of the first object. The selected area information of the first object is generated in response to the map modification operation and / or map reconstruction operation of the first user.

[0101] Specifically, the doctor (i.e., the first user) can select the section to be reconstructed and a local area of ​​that section on the MPR interface. The selected area information of the first object can be obtained by detecting the doctor's selection operation on the MPR interface. For example, the first terminal can obtain the selected area information of the first object by detecting the doctor's selection operation on the MPR interface and transmit it to the cloud server through the image report review unit.

[0102] In some implementations, the selected region information may include, but is not limited to, the selected location, region size, and normal vector. Here, the selected location may be the position of a point or region center point selected by the doctor in the MPR interface in a predetermined world coordinate system (e.g., a world coordinate system with a preset point in the human body such as the head or face as the origin). The region size may include the length, width, height, and other parameters set by the doctor in the MPR interface or the length, width, height, and other parameters configured by default. The normal vector is the normal vector of the cross-section where the point selected by the doctor in the MPR interface is located.

[0103] Step S46: Adjust the image report to be confirmed for the first object according to the image in the second report, so that the image report to be confirmed for the first object includes the image in the second report;

[0104] The pending image report for the first object may include, but is not limited to:

[0105] 1) Replace the first report image selected by the first user in the image report to be confirmed for the first object with the second report image to correct the error in the first report image;

[0106] 2) Add the second report image to the first subject's unconfirmed image report to make the first subject's unconfirmed image report more comprehensive and clear, so that the lesion can be clearly shown through the second report image and the first report image.

[0107] Therefore, when physicians review and revise imaging reports, if some images are unclear or inaccurate in location, affecting the diagnosis, or if images of certain lesions are omitted from the imaging report, local cross-sectional reconstruction can be performed on one or more areas through steps S44 to S46 to obtain local cross-sectional images with higher resolution and clarity. These images can then be used to replace or add to the imaging report to be confirmed if there may be errors, thereby outputting a higher quality imaging report.

[0108] Figure 5 The diagram illustrates the MPR (Mastering Performance Reconstruction) interface before doctor review. Doctors can access and log in to the first webpage via a browser. Through the MPR interface on this webpage, they can view visualized 3D images, axial section images, sagittal section images, and coronal section images of the teeth. If the doctor finds the lesion area unclear in the image report, they can select a suitable lesion area using the crosshair in the upper left corner of the MPR interface. After the doctor's selection, the cloud server automatically performs local section reconstruction of the selected lesion area. After the doctor's review and revision, the image report image more accurately reflects the lesion, and the MPR interface also more clearly displays the cross-section of the lesion. Figure 6 The MPR interface after doctor review is shown, compared to... Figure 5 , Figure 6 The MPR interface allows for a more accurate and clear display of the tooth's condition via cross-sections. Therefore, doctors can not only view visualized 3D images, axial section images, sagittal section images, and coronal section images of the primary object within the MPR interface, but also modify report illustrations using simple operations such as manipulating the crosshairs to reselect the lesion area or section.

[0109] See Figure 4 As shown, the image report generation method S40 may further include the following steps:

[0110] Step S48: Adjust the image report to be confirmed of the first object according to the second text description of the first object, so that the image report to be confirmed of the first object contains the second text description; wherein, the second text description of the first object is generated in response to the text editing operation of the first user.

[0111] Specifically, the doctor (i.e., the first user) can enter or edit text descriptions of the images in the image report review interface. A second text description of the first object can be obtained by detecting the doctor's text editing operations on the image report review interface. For example, the first terminal can obtain the second text description of the first object by detecting the doctor's text editing operations on the image report review interface and transmit it to the cloud server through the image report review unit.

[0112] In some implementations, the second textual description may include, but is not limited to, information such as the diagnosis of the lesion and the type of lesion.

[0113] In some implementations, adjusting the image report to be confirmed for the first object based on the second textual description of the first object may include, but is not limited to:

[0114] 1) Replace the first text description selected by the first user in the image report to be confirmed of the first object with the second text description to correct the error in the first text description;

[0115] 2) Add the second text description to the image report to be confirmed for the first object to make the image report to be confirmed for the first object more comprehensive and clear, and to make it easier to explain the condition of the lesion more clearly through the second text description and the first text description.

[0116] Therefore, when physicians review and revise imaging reports, if the text descriptions of some images are unclear or inaccurate, or if the text descriptions of some images are missing from the imaging report, the text descriptions in the imaging report can be modified through step S48, thereby outputting a higher quality imaging report.

[0117] See Figure 4 As shown, the image report generation method S40 may further include the following steps:

[0118] Step S41: In response to the second user's viewing operation, display a confirmation image report and / or a visualized 3D image of the first object to the second user.

[0119] In some implementations, the following text Figure 8 Taking the image report generation system shown as an example, after the cloud server generates a confirmation image report for the first object, it provides the confirmation image report for the first object to the patient (i.e., the second user) through the image report distribution unit. The patient can access the image report distribution unit using electronic devices such as computers and mobile terminals through tools such as applications or browsers. The patient performs a viewing operation in the interface of the application or browser, and the application or browser sends a request to the image distribution system of the cloud server. The image distribution system of the cloud server can then push the confirmation image report for the first object to the interface of the browser or application, and the patient can view the confirmation image report for the first object on the interface of the browser or application. Thus, it is convenient and fast for patients to view image reports in real time on various electronic devices. In addition, the viewing and display of confirmation image reports can also be achieved through other methods, which are not limited in this disclosure.

[0120] In some implementations, the image report distribution unit can be implemented as a second web service deployed on a cloud server. The image report distribution unit can provide a second webpage to a second terminal, confirming that the image report is displayed to a first user with viewing permissions through the second webpage. For example, the second user can access the second webpage using a browser or application on the second terminal. After logging in and authenticating, the user can view the second webpage, which supports operations such as film printing and image report browsing. The second terminal can be, but is not limited to, portable electronic devices, mobile devices, or other types of terminals.

[0121] In some implementations, the image report distribution unit may also have an MPR interface, which is used to display visualized 3D images, axial section images, sagittal section images, and coronal section images of the first object. After logging into the second webpage using a second terminal, the second user can jump to the MPR interface by clicking the MPR interface button on the second webpage or by other means to view the visualized 3D images, axial section images, sagittal section images, and coronal section images of the first object.

[0122] Currently, DICOM data format remains the standard medical imaging data format. However, this format is complex, requiring specialized software for parsing and viewing, making it less universally applicable to patients. Furthermore, most cloud service systems primarily function as backups of hospital data and physician services, and only support DICOM, making it cumbersome for ordinary patients to browse and view medical imaging reports. In this disclosure, the generation of imaging reports and the rendering of visualized 3D images are decoupled from the viewing process. This allows various mobile devices to view imaging reports and related images through applications or browsers. The visualized 3D images are rendered on the server side, allowing even mobile devices with limited GPU performance or portable electronic devices (e.g., laptops) to smoothly preview lesion-related images. Additionally, with the high transmission speed and low latency of 5G technology, the browsing experience on mobile devices will be indistinguishable from that on fixed electronic devices. Therefore, this disclosure, by providing imaging reports and visualized 3D images to patients through an imaging report distribution unit, greatly facilitates patients' access to medical imaging reports.

It not only allows AI neural networks to achieve self-learning and self-iteration on this system, but also decouples the display method of medical images from hardware and software, and adds functions that can better display image results and data. This greatly facilitates patients and improves doctors' work efficiency, freeing doctors from the heavy workload of writing and reviewing medical image reports, and enabling patients to intuitively and clearly understand their lesions and conditions.
