The completion may represent the completion of the scan of all sections of the stomach of the subject.

Wherein the scan direction represents the orientation of the ultrasound probe relative to the stomach. For example, with the mid-sagittal plane of the stomach as the reference frame, the direction perpendicular to the mid-sagittal plane is a scanning direction, referred to as the transverse direction; the direction parallel to the median sagittal plane is another scan direction, called the longitudinal direction. Of course, other scan directions may be defined according to other scan needs.

All sections required by ultrasonic scanning of the stomach of the detected person can be determined by a doctor according to the health condition of the detected person, namely, the doctor determines the section required to be scanned according to the actual health condition of the detected person when performing actual ultrasonic scanning of the stomach of the detected person; the determination of the sections required for the ultrasonic scanning of the stomach can also be carried out according to the expert consensus in the field, for example, the number of the standard sections required for the ultrasonic scanning of the stomach is generally 12-16. Of course, all of the sections required for the ultrasound scan of the stomach of the subject may be determined by other means, and this is not a limitation of the present embodiment.

It should be noted that, the present application is not limited to the execution sequence between the steps 203 and 204, and the step 203 may be executed first and then the step 204 may be executed; step 204 may be performed first, and then step 203 may be performed; steps 203 and 204 may also be performed simultaneously.

An embodiment of the present application will be described in further detail below on the basis of the foregoing embodiment shown in fig. 2. Referring to fig. 3, another embodiment of the method for prompting ultrasonic scanning of stomach according to the present application includes:

301. Obtaining stomach ultrasonic image data of a detected person;

In this embodiment, based on the structure and components of the ultrasound imaging apparatus shown in fig. 1, the processor 118 in the ultrasound imaging apparatus 100 may process the ultrasound echo signals to obtain stomach ultrasound image data of the subject. The gastric ultrasound image data may be either image data for displaying a two-dimensional gastric ultrasound image or three-dimensional volume data for displaying a three-dimensional gastric ultrasound image. The two-dimensional gastric ultrasound image data may be obtained by the processor 118 generating a frame of two-dimensional ultrasound image data from the echo data of each scan plane. The three-dimensional stomach image data is obtained by integrating the three-dimensional spatial relationship of the stomach ultrasonic echo signals obtained by scanning the ultrasonic probe 110 in a series of scanning planes by the processor 118, so as to realize the scanning of stomach tissues in the three-dimensional space and the reconstruction of the three-dimensional ultrasonic data. Finally, after partial or all image processing steps such as denoising, smoothing and enhancing, ultrasonic data of the stomach of the detected person, namely three-dimensional stomach ultrasonic image data, are obtained. For example, three-dimensional stomach ultrasonic image data can be acquired by a volume probe, can be reconstructed by a convex array or linear array probe with magnetic navigation equipment based on a three-dimensional ultrasonic reconstruction technology, or can be scanned by an area array probe.

302. Identifying a current scanning section according to the characteristics of the stomach ultrasonic image data, and determining a target scanning section to be scanned next to the current scanning section according to a preset scanning sequence;

In this embodiment, the types of the sections to be scanned may be divided according to the names of the respective portions of the stomach. As shown in FIG. 4, the stomach parts can be divided into cardiac, fundus, angle, body, pylorus and duodenum and antrum, and the scan planes obtained by the doctor performing ultrasonic filling examination on the stomach are the above parts of the stomach, namely the scan planes of the stomach comprise one or more of cardiac, fundus, body, angle, pylorus and duodenum and antrum planes. Therefore, the scanning section can be identified, the specific part of the scanning section corresponding to the stomach is identified, the section type of the scanning section is determined, and the section type can be determined according to the part corresponding to the scanning section. For example, a scan of the fundus is of the type; the type of the section of the stomach angle is the section of the stomach angle. Each section may also include one section or multiple sections corresponding to different scanning angles or different scanning positions, for example, a section of a stomach body may be understood as one or more scanning sections obtained by performing ultrasonic scanning on the stomach body.

The ultrasound images of the sections of different stomach sites are significantly different, and fig. 5 and 6 are respectively the ultrasound image of the cardiac section and the ultrasound image of the gastric angular section of the same patient, as shown in fig. 5 and 6, the ultrasound image of the cardiac section generally includes liver parenchyma, and the ultrasound image of the gastric angular section generally has a folded curved 10-layer structure. Therefore, a model or algorithm can be constructed based on the differential characteristics among different sections, and the detection of the corresponding part of the stomach ultrasonic image and the judgment of the section type can be realized by using the model or algorithm.

Specifically, the section type of the currently scanned section is identified according to the characteristics of the stomach ultrasonic image data, and the method comprises the following various modes:

One way of the method can be that the stomach ultrasonic image data is input into a stomach section identification model which is trained in advance, the stomach section identification model extracts the characteristics of the stomach ultrasonic image data and identifies the stomach section corresponding to the stomach ultrasonic image data according to the characteristics, and the section type of the current scanning section output by the stomach section identification model is obtained. The stomach section identification model can be a deep learning model obtained by training a plurality of groups of stomach ultrasonic images based on a deep learning algorithm, wherein the deep learning model comprises but is not limited to AlexNet, resnet, VGG neural network models. In the model training process, a plurality of groups of training samples are input into a deep learning model, each group of training samples comprises a stomach ultrasonic image and corresponding pre-labeled label information thereof, the label information represents the section type of a scanning section corresponding to the stomach ultrasonic image, the deep learning model predicts the section type corresponding to the stomach ultrasonic image according to each group of input training samples, and model parameters are updated according to errors between a prediction result and actually labeled label information. Therefore, through the training process, the deep learning model can be continuously and iteratively updated, so that the prediction result output by the model gradually approaches to the actually marked label information, and finally the classification model with the ability of identifying the section type of the stomach ultrasonic image is obtained.

The other mode can be that based on a feature extraction algorithm, the image features of the stomach ultrasonic image data are extracted, the image features are input into a pre-trained machine learning model, and the machine learning model predicts the stomach section corresponding to the stomach ultrasonic image data according to the image features to obtain the section type of the current scanning section output by the machine learning model. The image features include, but are not limited to, image gray features, texture features, shape features of the stomach cavity or wall, etc., the image features are input SVM, kmean, KNN into a machine learning model, etc., and the machine learning model is used to predict the section type to obtain the section type identification result of the stomach ultrasound image.

The method for identifying the section type of the current scanning section can also be used for extracting the image characteristics of the stomach ultrasonic image data based on a characteristic extraction algorithm, and determining the section type of the scanning part corresponding to the preset characteristic threshold as the section type of the current scanning section when the characteristic value of the image characteristics reaches the preset characteristic threshold. The division can be performed based on image features according to a preset threshold, wherein the threshold can be the overall direction, roundness, radial length, area and the like of the stomach wall, and when the feature value of any feature reaches the feature threshold of the feature, the position corresponding to the stomach ultrasonic image data can be determined to be the position corresponding to the feature threshold, namely the section type corresponding to the stomach ultrasonic image data is the section of the position. For example, it may be determined whether the feature value of the roundness-like feature of the gastric ultrasound image reaches the feature threshold of the roundness-like feature of the gastric antrum, and if so, it is determined that the portion corresponding to the ultrasound image is the gastric antrum, that is, the type of the section corresponding to the ultrasound image is the gastric antrum section.

Therefore, the method and the device can identify the section type of the scanning section corresponding to the stomach ultrasonic image data according to the algorithm or the model, can quickly obtain the identification result of the section type, and improve the data processing progress, thereby quickly responding to the image display requirement of the subsequent step.

In this embodiment, the preset scanning sequence may be a scanning sequence set by the user, or may be a scanning sequence commonly known by medical professionals in the field, or may be a scanning sequence formed by the ultrasound imaging device according to a history record of performing the ultrasound scanning of the stomach by the user. The method for acquiring the preset scanning sequence is not limited in this embodiment.

303. Determining a scanning direction corresponding to the target scanning section;

In this embodiment, each scanning section is preset with a corresponding scanning direction and a scanning position, so that the scanning direction corresponding to the target scanning section can be determined, so as to instruct the user to operate the ultrasonic probe based on the corresponding scanning direction to perform the scanning of the target scanning section.

304. Determining the degree of completion of the section that has been scanned relative to all sections required for ultrasound scanning of the stomach;

Whether the section is scanned or not can be judged according to preset rules. For example, the preset rule may be that the ultrasound probe stays in the current scan plane for a preset time, which may be 3 to 5 seconds, or other times, such as 3 seconds for the ultrasound probe to stay in the corner region of the stomach, the scan of the corner section is determined to be complete. The preset rule may also be that if it is detected that the user performs the save operation on the ultrasound image corresponding to the current scanning section, it is determined that the user completes the scanning of the current scanning section. And then, updating the scanning progress, namely updating the completion degree, in real time according to the completed scanning section.

In this embodiment, the completion degree may be calculated in a plurality of ways, and one of the calculation ways may be to determine a ratio of the scanned section among all sections required for performing the ultrasonic scanning on the stomach of the subject, and use the ratio as the completion degree of the ultrasonic scanning. For example, the expert in the field has agreed that the number of all sections required for performing an ultrasonic scan on the stomach is 16, and the 16 sections are scanned sequentially in order, and if the first 8 sections are currently scanned, the ratio of the scanned sections is 50%, that is, the degree of completion is 50%.

The other calculation mode of the completion degree may be that the user can preset the weight of the scanning section of each part according to the importance of different parts of the stomach to the stomach examination of the patient, for example, the gastric angle section and the large curved section of the stomach body part are also the gastric angle section and the large curved section, and since the gastric angle is the frequent part of the stomach diseases, the weight of the gastric angle section can be set to be 10% of the total weight (100%), and the morbidity of the large curved side of the stomach body is less, so the weight of the large curved section is set to be less than 5%. Thus, after the preset weight of each section required for ultrasonic scanning of the stomach is set, the sum of the preset weights of the sections which are scanned can be calculated, and the sum is used as the completion degree of ultrasonic scanning. For example, when the sum reaches 100%, it indicates that the ultrasound scan of all sections of the stomach has been completed.

For example, as shown in fig. 7, the weight corresponding to the scan plane of each portion of the stomach may be set, for example, the weight of the cardiac plane is set to 10% of the total weight (100%), the weight of the fundus plane is set to 20% of the total weight (100%), the weight of the gastric plane is set to 40% of the total weight (100%), and so on. The sum of the weights of all the sections is 100%, i.e., when the section scanning of all the sections shown in fig. 7 is completed, the degree of completion is 100% of the sum of the weights of all the sections.

Of course, instead of representing the degree of completion in terms of a percentage, the degree of completion may also be represented in terms of a score. For example, the expert in the field has agreed that the number of all sections required to perform an ultrasound scan on the stomach is 16, and if the first 8 sections are currently being scanned, the degree of completion may be indicated as 8/16, and the progress of the ultrasound scan may also be indicated. The method of determining the completion of the ultrasound scanning is not limited in this embodiment.

It should be noted that, the present application is not limited to the execution sequence between the steps 303 and 304, and the step 303 may be executed first and then the step 304 may be executed; step 304 may be performed first, and then step 303 may be performed; steps 303 and 304 may also be performed simultaneously.

305. Displaying a stomach model, displaying the name of the current scanning section and the corresponding position of the current scanning section in the stomach model, displaying the name of the target scanning section and the corresponding position and scanning direction of the target scanning section in the stomach model, and displaying the completion degree;

in this embodiment, the stomach model is generated based on the anatomical structure of the human stomach, so that each part in the stomach model may correspond to a part in the anatomical structure of the human stomach, for example, the cardiac part shown in the stomach model in fig. 4 corresponds to the cardiac part in the anatomical structure of the human stomach, and the fundus part shown in the stomach model corresponds to the fundus part … … in the anatomical structure of the human stomach, so that the scan section obtained by the doctor actually performing the ultrasound scan on each part of the stomach may be displayed on the corresponding part in the stomach model, so that the doctor can confirm the current part of the ultrasound scan.

The method comprises the step of displaying the corresponding position of the current scanning section corresponding to the stomach ultrasonic image data in the stomach model, wherein the mode can be that the corresponding position of the current scanning section in the stomach model displays the current scanning section in a section with a preset shape. By displaying the section on the stomach model to represent the corresponding position of the current scanning section in the stomach model, the section is more vivid and specific in a graphical display mode, and a user can intuitively see the scanned position of the current scanning section through the stomach model.

Of course, instead of displaying the current scan slice with a slice of a preset shape, the position of the current scan slice in the stomach model may be represented in other ways, such as pointing with an arrow to the corresponding position of the current scan slice in the stomach model, or prompting with text the corresponding position of the current scan slice in the stomach model. The display mode of the corresponding position of the current scanning section in the stomach model is not limited in the embodiment.

In this embodiment, the part of the stomach model where the scanning is completed and the part where the scanning is not completed may be displayed differently, that is, the part corresponding to the section of the stomach model where the scanning is completed is displayed in the first display mode, the part corresponding to the section of the stomach model where the scanning is not completed is displayed in the second display mode, and the completion is displayed in the stomach model where the part is displayed in the first display mode. Wherein the first display mode is different from the second display mode.

The part displayed in the stomach model in the first display mode and the part displayed in the second display mode can be different in any display effect, for example, can be different in color, can be different in the size of the displayed area, can be different in the word pattern displayed when the part which is not scanned and the part which is scanned are marked by words, and the like.

When the stomach model displays the next target scanning section to be scanned, a corresponding directivity mark can be displayed, the direction indicated by the directivity mark represents the scanning direction of the target scanning section, and the position of the directivity mark represents the corresponding position of the target scanning section in the stomach model.

For example, as shown in fig. 8, in the stomach model, the ground color of the part that has been scanned is shown as a gray shade, while the ground color of the part that has not been scanned is shown as the original ground color of the stomach model, it can be seen from the figure that the cardiac part and the fundus part of the stomach model are shown as gray shades, indicating that the part has been scanned, and the degree of completion of the ultrasonic scan is 30% with respect to all the sections required for the ultrasonic scan of the stomach.

Meanwhile, the current scanning section is identified as a stomach body transverse cutting, and then in a stomach model, the current scanning section is displayed on a stomach body part by a rectangular section, and a user can know that the current scanning section is the stomach body section and the scanning direction is the transverse cutting direction by observing the stomach model.

And displaying an arrow below the current scanning section shown in the stomach model, wherein the arrow indicates the position and the method of the next section of the current scanning section, the method comprises the scanning direction, a user can know that the arrow is positioned at the stomach body part by observing the arrow, the next target scanning section to be scanned is the stomach body section, the scanning direction is the longitudinal cutting direction, and the next section to be scanned can be determined to be the stomach body longitudinal cutting section. Wherein the scan direction represents the orientation of the ultrasound probe relative to the stomach. For example, with the mid-sagittal plane of the stomach as the reference frame, the direction perpendicular to the mid-sagittal plane is a scanning direction, referred to as the transverse direction; the direction parallel to the median sagittal plane is another scan direction, called the longitudinal direction. Of course, other scan directions may be defined according to other scan needs.

Similarly, in the stomach model shown in fig. 9, the cardiac, fundus and somatic stomach portions of the stomach model were observed to show gray shading, indicating that the portions were all completely scanned, and that the completion of the section scanning was 70% with respect to all sections required for the stomach ultrasound scanning. Meanwhile, when the current scanning section is identified as the stomach angle section, a rectangular section is displayed at the stomach angle part of the stomach model, and the current scanning section is indicated as the section of the stomach angle. And displaying an arrow below the current scanning section shown in the stomach model, wherein the arrow indicates that the position where the next section of the stomach angular section should be scanned is the antrum of the stomach, the scanning method is transverse scanning, and a user can know the section to be scanned next and the specific scanning mode by observing the mark in the stomach model.

Fig. 8 and 9 show the scan site and scan direction indicated by arrows that can be highlighted to alert the physician to the next scan slice. In addition, besides the arrow, other marks can be used to represent the corresponding position of the next target scanning section to be scanned in the stomach model and the scanning direction thereof, for example, marks representing the orientation of the space section by a transparent surface, a guide line, a track line and the like can be equivalent to the arrow.

Of course, although the drawing shows the scanning section as a rectangular section, the scanning section may be shown as a section of another shape, for example, a sector section or a circular section. In addition, a virtual ultrasonic probe model can be displayed in the stomach model, and the position and the orientation of the ultrasonic probe model are displayed so as to show the scanning position and the scanning direction of the current scanning section. The manner in which the current scan slice is shown in the embodiment of the present application is not limited, as long as the spatial slice orientation of the slice can be shown, and the method is not limited herein.

306. When the ultrasonic scanning of the stomach is detected to be finished, if an unclean section exists in the preset scanning sequence, a prompt message is sent to prompt a user to miss the scanning of the unclean section;

In this embodiment, when there are non-scanned sections in the preset scanning sequence of all sections required for the ultrasonic stomach scanning, a prompt message may be sent to prompt the user to miss the scanning of the non-scanned sections. The prompting information may be alarm voice, popup window content displayed by a display or other types of prompting information, and the prompting mode is not limited.

The method comprises the steps of detecting that the ultrasonic scanning of the stomach is finished, wherein the method can be used for detecting that a user finishes the scanning of the last section in the preset scanning sequence, namely determining that the ultrasonic scanning of the stomach is finished; it is also possible to detect that the user turns off the ultrasound probe, i.e. the user is considered to have ended the stomach ultrasound scanning.

The method for prompting the missing scanning is executed when the stomach ultrasonic scanning is finished, and in the execution process of the stomach ultrasonic scanning, if a user skips the scanning of a certain section in the preset scanning sequence, the user can be prompted to perform the missing scanning in real time. Specifically, when the next scanning section of the current scanning section executed by the user is detected to be inconsistent with the target scanning section determined according to the preset scanning sequence, a prompt message may also be sent to prompt the user that the scanned section is inconsistent with the target scanning section determined according to the preset scanning sequence.

For example, if the preset scan sequence is cardiac, fundus, corpus, antrum, pylorus and duodenum, and the current scan plane is the undercut plane of the stomach, then the user directly scans the antrum, it is determined that the user missed the scan of the corpus, and a prompt message may be sent to prompt the user to missed the scan. The user may stop the scanning of the antrum region and return to perform the scanning of the gastric body region, or may return to perform the scanning of the gastric body region after the completion of the scanning of the antrum region.

Therefore, by prompting missing scanning, the user can know the part which is not scanned, and assist the user to perform missing and leakage repairing on the ultrasonic scanning operation, so that missing scanning is avoided.
