[0073] The present application will be further described in detail below with reference to the accompanying drawings.

[0074]

First Embodiment

[0075] In order to improve the generation efficiency of an ultrasound examination report and improve the overall efficiency of an ultrasound examination, a method for assisting in generating a structured report in a medical examination is specifically disclosed. Referring to Figure 1 , the method comprises the following steps:

[0076] S10: generating an operation guide step in response to a category examination instruction;

[0077] The mentioned response category examination instruction can be a category examination instruction input by the doctor for the examination site required by the patient. The category examination can be an examination on a certain part of the cardiovascular blood vessels, such as an examination on the carotid artery. The mentioned generation of the operation guide step can be understood as generating the guide step of the corresponding category examination according to the category examination instruction input by the doctor, so as to assist the doctor in selecting the corresponding examination item for the examination site of the blood vessels, so as to avoid missed diagnosis of the examination item, and facilitate the flexible selection of the examination item by the doctor, and increase the work efficiency of the doctor.

[0078] S20: performing examination on the first static site image to obtain first examination data;

[0079] The first static site image is a static image collected from the input first initial examination site image according to the operation guide step; the first static site image includes a blood vessel site; the first examination data includes plaque suspected information, and also includes pipe diameter information or blood flow information of the blood vessel site;

[0080] Specifically, for example, the first initial examination site image is a real-time collected image of the common carotid artery blood vessel site. The blood vessel site can be a starting segment of the common carotid artery, a middle segment of the common carotid artery, and a distal segment of the common carotid artery. The starting segment of the common carotid artery is located at the proximal end. The middle segment of the common carotid artery can be understood as a segment located between the starting segment of the common carotid artery and the distal segment of the common carotid artery, and the appearance of the segment is spherical. The distal segment of the common carotid artery is located at the distal end. The pipe diameter information can include identification information of a blood vessel pipe diameter measurement value and identification information of a blood vessel wall stenosis region. The identification information of the blood vessel pipe diameter measurement value can be understood as information of a pipe diameter size measured based on the determination of a target measurement point in the pipe diameter. The identification information of the blood vessel wall stenosis region can be understood as that there is a bump in the inner wall of the blood vessel pipe diameter. The bump can be a plaque, which forms a stenosis region with the blood vessel pipe diameter. The stenosis region is identified by a target detection method or a convolution network to obtain information such as blood flow velocity and region size of the stenosis region. The blood flow information can include blood flow velocity, blood vessel resistance index, and blood flow peak time in the blood vessel. It is stated herein that the information collection of the blood vessel examination site is not limited in the present application, and can be designed according to actual needs.

[0081] Referring to Figure 2 In the embodiment, step S20 specifically includes:

[0082] S21: judging an image mode to which the first static site image belongs based on the first static site image; wherein the image mode to which the first static site image belongs is one of a two-dimensional gray scale mode, a color mode, or a Doppler mode;

[0083] Referring to Figures 3A-3C , the image mode includes Figure 3Aa two-dimensional gray mode, Figure 3B a color mode and Figure 3B a Doppler mode. The color mode image is superimposed with a color blood flow coverage area shown as A in the figure compared to the two-dimensional gray mode image. The Doppler mode adds a spectrum image shown as B in the figure compared to the color mode.

[0084] S22: matching an examination item corresponding to the image mode of the first static site image based on the image mode of the first static site image;

[0085] For example, when the image mode of the first static site image is a two-dimensional gray mode, a detection item for examining a blood vessel diameter is matched. When the image mode of the first static site image is a color mode, an examination item for examining a blood flow coverage area is matched. When the image mode of the first static site image is a Doppler mode, an examination item for examining a blood flow coverage area and a blood flow hemodynamic characteristic is matched.

[0086] S23: performing examination processing on the first static site image according to the examination item to obtain first examination data.

[0087] S30: performing plaque analysis on a second static site image in combination with the first examination data to obtain second examination data;

[0088] The second static site image is a static image collected from an input second initial examination site image according to an operation instruction step. The second static site image includes a blood vessel site. The image mode of at least one of the first static site image and the second static site image is a color mode or a Doppler mode. The second examination data includes plaque result information and also includes vessel diameter information or blood flow information of the blood vessel site.

[0089] Referring to Figure 4 , the step S30 specifically includes:

[0090] S31: judging an image mode of the second static site image based on the second static site image;

[0091] For example, the image mode of the second static site image can be judged by recognizing text information in the image through OCR (optical character recognition) and recognizing image features based on convolution network Fast-CNN, yolo, etc. It is to be noted that the embodiment is not limited in this regard and any method achieving the same effect can be used.

[0092] S32: if the image mode of the second static site image is a color mode or a Doppler mode, comparing a similarity of the blood vessel site in the first static site image and the second static site image.

[0093] Wherein, by recognizing the similarity of the first static site image and the second static site image, it can be determined whether they are the same blood vessel site.

[0094] S33: If the similarity meets the preset similarity, it is determined that the first static site image and the second static site image are images of the same blood vessel site.

[0095] Wherein, the preset similarity can be 80%, for example, when the similarity of the first static site image and the second static site image exceeds 80%, it can be concluded that they are the same blood vessel site, for example, the same starting segment of the common carotid artery. In addition, the presence or absence of a blood vessel site plaque can be further determined based on the similarity of the two.

[0096] S34: Based on the first examination data, the coverage area of the color blood flow in the second static site image is determined for the plaque suspected information, and the second examination data is obtained.

[0097] Referring to Figure 5 In another embodiment, step S30 specifically includes:

[0098] S301: Based on the second static site image, the image mode is determined.

[0099] S302: If the image mode is a two-dimensional gray scale mode, the plaque suspected information and the blood vessel diameter information are identified based on the second static site image.

[0100] S303: Compare the similarity of the blood vessel site in the first static site image and the second static site image.

[0101] S304: If the similarity meets the preset similarity, it is determined that the first static site image and the second static site image are images of the same blood vessel site.

[0102] S305: In combination with the color blood flow coverage area in the first static site image, the plaque suspected information is analyzed to obtain the plaque result information.

[0103] Wherein, it is explained that the first static site image is in color mode or Doppler mode, so as to provide a color blood flow coverage area of the blood vessel site, and then analyze and judge the situation of the plaque suspected information, for example, if it is judged that there is no plaque, the next operation step is instructed to be executed; if it is judged that there is a suspected plaque area, it is further judged whether the blood flow covers the edge of the plaque, if not, the blood vessel site boundary is updated in the image according to the blood flow situation, and then the best measurement point of the plaque long diameter, short diameter and tube diameter is updated, that is, the size of the plaque is updated, so as to adjust the plaque lesion confidence to 100%; in addition, the type of the plaque is judged and updated based on the gray scale gradient, which can be specifically based on the gray scale gradient to judge the bright area and dark area of the plaque, based on the combination of the bright area and the dark area to obtain the boundary contour of the plaque, and based on the boundary contour of the plaque to determine the type of the plaque; if the plaque edge dark area is covered by blood flow, the type of the plaque is updated to ulcer plaque.

[0104] In addition, if the first static site image is in Doppler mode, it is also necessary to identify whether there is a blood flow spectrum image in the image, and identify the blood flow hemodynamic characteristics and image characteristics presented by the spectrum image, the blood flow hemodynamic characteristics including the blood flow peak value, the blood flow end value, the peak time of the spectrum graph, and the PI pulsation index and the RI resistance index calculated according to the blood flow peak value and the end value, the blood flow spectrum characteristics including single-peak type, notch and other spectrum characteristics, and these information is updated in the first static site image. Of course, if there is no effective spectrum data, no update is performed.

[0105] Of course, it is explained that when the first static site image and the second static site image are both in two-dimensional gray mode, the color blood flow coverage area can be obtained based on the second initial examination site image or the image is reacquired, so as to realize the analysis of the plaque suspected information.

[0106] S306: Based on the plaque result information and the information of the blood vessel diameter, the second examination report is obtained.

[0107] S40: Based on the first examination data and the second examination data, an examination report is generated, wherein the examination report includes the information of the blood vessel diameter, the blood flow information in the blood vessel and the plaque result information.

[0108] In another embodiment, before step S20, it further includes:

[0109] Based on the operation instruction step, the first initial examination site image is obtained in response to the acquisition instruction of the examination site image in the operation instruction step;

[0110] Wherein, the first initial examination site image can be input by the doctor according to the instruction step, or be called from the pre-stored data in the database.

[0111] performing image screening processing on the first initial examination site image to obtain a first static site image.

[0112] The step S20 specifically comprises:

[0113] collecting a static site image based on the first initial examination site image;

[0114] The collecting of the static site image can be random collection based on the first initial examination site image.

[0115] taking a picture snapshot of images of the static site image in the first initial examination site image at a preset time before and after the static site image to obtain a plurality of static snapshot images;

[0116] The preset time is, for example, 300 ms. For example, a picture snapshot is taken of images of the static site image in the first initial examination site image at 300 ms before and after the randomly collected static site image to obtain a plurality of static snapshot images.

[0117] performing definition analysis processing on the plurality of static snapshot images to select a first static site image;

[0118] The definition analysis processing can be understood as a comparison and judgment of pixel points and resolution of the pictures, and the best picture is selected as the first static site image to ensure the accuracy of subsequent picture feature recognition.

[0119] In another implementation, before the step S30, the method further comprises:

[0120] based on the operation instruction step, in response to the collection instruction of the examination site image in the operation instruction step, obtaining a second initial examination site image;

[0121] The second initial examination site image can be real-time detection and input by a doctor according to the instruction step, or be called from pre-stored data in a database. Of course, in the embodiment, the second initial examination site image and the first initial examination site image can also be the same image.

[0122] performing image screening processing on the second initial examination site image to obtain a second static site image.

[0123] The step S30 specifically comprises:

[0124] collecting a static site image based on the second initial examination site image;

[0125] The mentioned static part image can be a static image randomly collected based on the second initial examination part image.

[0126] Based on the static part image, picture snapshots are taken of images before and after the static part image in the second initial examination part image by a preset time to obtain a plurality of static snapshot images.

[0127] The preset time is, for example, 300 ms. For example, based on the randomly collected static part image, picture snapshots are taken of images before and after the static part image in the second initial examination part image by 300 ms to obtain a plurality of static snapshot images.

[0128] The plurality of static snapshot images are subjected to definition analysis processing to select a second static part image.

[0129] The definition analysis processing can be understood as a comparison and judgment of pixel points and resolution of the pictures to select the best picture as the second static part image to ensure the accuracy of subsequent picture feature recognition.

[0130] To better understand the present embodiment, the following will be described in combination with Figure 6 The specific implementation of the present embodiment will be described by way of example.
